NU 272 Practice Exam (HESI) | Questions, Answers and Rationales A male client with chronic atrial fibrillation and a slow ventricular response is scheduled for surgical placement of a permanent pace... maker. The client asks the nurse how this device will help him. How should the nurse explain the action of a synchronous pacemaker? An electrical stimulus is discharged when no ventricular response is sensed. The artificial cardiac pacemaker is an electronic device used to pace the heart when the normal conduction pathway is damaged or diseased, such as a symptomatic dysrhythmias like atrial fibrillation with a slow ventricular response. Pacing modes that are synchronous (impulse generated on demand or as needed according to the patient's intrinsic rhythm) send an electrical signal from the pacemaker to the wall of the myocardium stimulating it to contract when no ventricular depolarization is sensed. The nurse is caring for a client with end stage liver disease who is being assessed for the presence of asterixis. To assess the client for asterixis, what position should the nurse ask the client to demonstrate? Extend the arm, dorsiflex the wrist, and extend the fingers. Asterixis (flapping tremor, liver flap) is a hand-flapping tremor that is often seen frequently in hepatic encephalopathy. The tremor is induced by extending the arm and dorsiflexing the wrist causing rapid, non-rhythmic extension and flexion of the wrist while attempting to hold position. The nurse is giving discharge instructions to a client with chronic prostatitis. What instruction should the nurse provide the client to reduce the risk of spreading the infection to other areas of the client's urinary tract? Have intercourse or masturbate at least twice a week. The prostate is not easily penetrated by antibiotics and can serve as a reservoir for microorganisms, which can infect other areas of the genitourinary tract. Draining the prostate regularly through intercourse or masturbation decreases the number of microorganisms present and reduces the risk for further infection from stored contaminated seminal fluids. Which action should the nurse implement on the scheduled day of surgery for a client with type 1 diabetes mellitus (DM)? Obtain a prescription for an adjusted dose of insulin. Stressors, such as surgery, increase serum glucose levels. A client with type 1 DM who is NPO for scheduled surgery should receive a prescribed adjusted dose of insulin. A client with osteoarthritis receives a prescription for Naproxen (Naprosyn). Which potential side effect should the nurse provide to the client about this medication? Gastrointestinal disturbance. Prostaglandin synthesis inhibitors such as naproxen can have gastrointestinal side effects such as nausea and gastric burning. It is recommended that this drug be taken with food to avoid gastrointestinal upset. The nurse is caring for a male client who had an inguinal herniorrhaphy 3 hours ago. The nurse determines the client's lower abdomen is distended and assesses dullness to percussion. What is the priority nursing action? Determine the time the client last voided. Swelling at the surgical site in the immediate postoperative period can impact the bladder and prostate area causing the client to experience difficulty voiding due to pressure on the urethra. To provide additional data supporting bladder distention, the last time the client voided should be determined next. When teaching a client with breast cancer about the prescribed radiation therapy for treatment, what information is important to include? Dry, itchy skin changes may occur. Side effects from radiation to the breast most often include temporary skin changes such as: dryness, tenderness, redness, swelling, and pruritis. Which finding should the nurse identify as an indication of carbon monoxide poisoning in a client who experienced a burn injury during a house fire? Cherry red color to the mucous membranes. The saturation of hemoglobin molecules with carbon monoxide molecules, instead of oxygen molecules and the subsequent vasodilation induced cherry red color of the mucous membranes is an indication of carbon monoxide poisoning. What assessment finding should the nurse identify that indicates a client with an acute asthma exacerbation is beginning to improve after treatment? Wheezing becomes louder. In an acute asthma attack, air flow may be so significantly restricted that breath sounds and wheezing is diminished. If the client is successfully responding to bronchodilators and respiratory treatments, wheezing should become louder as the air flow increases in the airways. As the airways open and mucous is mobilized in response to treatment, the cough should become more productive. The nurse is caring for a client with human immunodeficiency virus (HIV) infection who develops Mycobacterium avium complex (MAC). What is the most significant desired outcome for this client? Return to pre-illness weight. MAC is an opportunistic infection that presents as a tuberculosis-like pulmonary process. MAC is a major contributing factor to the development of wasting syndrome, so the most significant desired outcome is the client's return to a pre-illness weight using oral, enteral, or parenteral supplementation as needed. The nurse obtains a client's history that includes right mastectomy and radiation therapy for cancer of the breast 10 years ago. Which current health problem should the nurse consider is a consequence of the radiation therapy? Pathologic fracture of two ribs on the right chest. The ribs lie in the radiation pathway and lose density over time, becoming thin and brittle, so the occurence of two right-sided ribs with pathological fractures resulting without evidence of trauma is related to radiation damage. A client is admitted to the emergency department after being lost for four days while hiking in a national forest. Upon review of the laboratory results, the nurse determines the client's serum level for thyroid-stimulating hormone (TSH) is elevated. Which additional assessment should the nurse make? Exposure to cold environmental temperatures. TSH influences the amount of thyroxine secretion which increases the rate of metabolism to maintain body temperature near normal. Prolonged exposure to cold environmental temperatures stimulates the hypothalamus to secrete thyrotropin-releasing hormone, which increases anterior pituitary serum release of TSH. An older female client is admitted with atrophic vaginitis and perineal cutaneous candidiasis. What is the priority nursing diagnosis for this client? Impaired comfort. In menopausal women, the vaginal mucous membrane responds to low estrogen levels causing the vaginal walls to become thinner, drier, and susceptible to infection which leads to atrophic vaginitis. Perineal cutaneous candidiasis contributes to other manifestations of vaginal infections, such as vaginal irritation, burning, pruritus, increased leukorrhea, bleeding, and dyspareunia, which supports the primary nursing diagnosis, "Impaired comfort". The nurse is caring for a client scheduled to undergo insertion of a percutaneous endoscopic gastrostomy (PEG) tube. The client asks the nurse to explain how a PEG tube differs from a gastrostomy tube (GT). Which explanation best describes how they are different? Method of insertion. The best explanation of how a PEG tube differs from a GT is by the method of insertion. GT insertion involves making an incision in the wall of the abdomen and suturing the tube to the gastric wall. A PEG tube is more commonly used due to the fact it does not require general anesthesia and less invasive due to being inserted with endoscopic visualization through the esophagus into the stomach and then pulled through a small incision in the abdominal wall and held in place by a tiny plastic device called a "bumper" that holds the g-tube in place inside the stomach and a small water-filled balloon which keeps the stomach in place against the abdominal wall. Which sexually transmitted infection (STI) should the nurse include in a client's teaching plan about the risk for cervical cancer? Human papillomavirus. According to the CDC (2017), it is estimated at least 80% of all women who are sexually active will contract the Human papillomavirus (HPV) in their lifetime. Certain types of HPV have been suspected to cause cervical cancer and HPV strain 16 and 18 have been identified to cause 70% of cervical cancers. The home health nurse is assessing a client with terminal lung cancer who is receiving hospice care. Which activity should be assigned to the hospice practical nurse (PN)? Administer medications for pain relief, shortness of breath, and nausea. Hospice care provides symptom management and pain control during the dying process and enhances the quality of life for a client who is terminally ill. Administering medication and monitoring for therapeutic and adverse effects is within the scope of practice for the PN. The nurse is assessing a client with a chest tube that is attached to suction and a closed drainage system. Which finding is most important for the nurse to further assess? Upper chest subcutaneous emphysema. Subcutaneous emphysema is a complication and indicates air is leaking beneath the skin surrounding the chest tube. A man who smokes two packs of cigarettes a day wants to know if smoking is contributing to the difficulty that he and his wife are having getting pregnant. What information is best for the nurse to provide? (Select all that apply.) Smoking can decrease the quantity and quality of sperm. The use of tobacco, alcohol, and marijuana may affect a man's sperm counts. A client who has just tested positive for human immunodeficiency virus (HIV) does not appear to hear what the nurse is saying during post-test counseling. Which information should the nurse offer to facilitate the client's adjustment to HIV infection? Discuss retesting to verify the results, which will ensure continuing contact. Encouraging retesting supports hope and gives the client time to cope with the diagnosis. Although post-test counseling should include education, retesting encourages the client to maintain medical follow-up and management. When caring for a client with a percutaneous endoscopic gastrostomy (PEG) tube, what protocols should the nurse implement for intermittent feedings? (Select all that apply.) Keeping the head of the bed elevated 30 degrees, changing the enteral-feeding bag every 24 hours, checking the placement of the tube by means of gastric aspiration, and flushing the tube with 50 ml of normal saline solution after each feeding are interventions used to provide care of the client with a PEG tube. Residual amounts should be assessed each time, prior to each feeding. The nurse is caring for a client who is admitted with a hemorrhagic stroke. Which nursing action should be included in the plan of care? Teach measures to avoid the Valsalva maneuver. The Valsalva maneuver, straining with bowel movements while holding one's breath, increases intracerebral pressure (ICP) which may induce bleeding or rupture of cerebral blood vessels. A female client with type 2 diabetes mellitus reports dysuria. Which assessment finding is most important for the nurse to report to the healthcare provider? Fingerstick glucose of 300 mg/dl. Elevated fingerstick glucose levels needs to be reported to the healthcare provider, so a plan of care can be adjusted to treat the elevated glucose level. Also elevated glucose levels, spills into the urine and provide a medium for bacterial growth. In planning care for a client with an acute stroke resulting in right-sided hemiplegia, which positioning should the nurse should use to maintain optimal functioning? Left lateral, supine, brief periods on the right side, and prone. After an acute stroke, a positioning and turning schedule that minimizes lying on the affected side, which can impair circulation and cause pain, and includes the prone position to help prevent flexion contractures of the hips, prepares the client for optimal functioning and ambulating. The PET (positron emission tomography) scan is commonly used with oncology clients to provide for which diagnostic information? An image that describes metastatic sites of cancer. PET scans provide information regarding certain diseases of the heart (determination of tissue viability), brain (dementia, Parkinson's disease), and early detection of tumors and their metastasis. A client with acute appendicitis is experiencing anxiety and loss of sleep about missing final examination week at college. Which outcome is most important for the nurse to include in the plan of care? Achieve a sense of control. The experience of psychological discomfort may be as real as physical pain for the client and should be seen as a priority in care. Because the client is experiencing anxiety, achieving a sense of control is the overall outcome of this client's nursing care plan. The nurse is caring for a client with a small bowel obstruction. The client is vomiting foul smelling fecal-like material. What action should the nurse implement? Give IV fluids with electrolytes. When the bowel is obstructed, electrolytes and fluids are not absorbed, so parenteral fluids with sodium chloride, bicarbonate, and potassium should be administered to prevent electrolyte imbalance and dehydration. Three weeks after discharge for an acute myocardial infarction (MI), a client returns to the cardiac center for follow-up. When the nurse asks about sleep patterns, the client tells the nurse that he sleeps fine but that his wife moved into the spare bedroom to sleep when he returned home. He states, "I guess we will never have sex again after this." Which response is best for the nurse to provide? Sexual activity is similar in cardiac workload and energy expenditure as climbing two flights of stairs and may be resumed like other activities. Sexual intercourse after an MI, or acute coronary syndrome, has been found to require no more energy expenditure or cardiac stress than walking briskly up two flights of stairs, so if you do not experience shortness of breath or chest discomfort doing the stairs then you should be okay to resume sexual activity. A young adult female reports that she is experiencing a lack of appetite, hypersomnia, stress incontinence, and heart palpitations. Which symptom is characteristic of premenstrual syndrome? Heart palpitations. Characteristic features of premenstrual syndrome include heart palpitations, sleeplessness, increased appetite and food cravings, and oliguria or enuresis. The nurse assesses a long-term resident of a nursing home and finds the client has a fungal infection (candidiasis) beneath both breasts. To prevent nosocomial infection, which protocol should the nurse review with the rest of the staff? Wash hands after caring for the client. The organism Candida albicans, that causes this infection, is part of the normal flora on the skin of most adults. Good handwashing is all that is needed to prevent nosocomial spread. A client with acute osteomyelitis has undergone surgical debridement of the diseased bone and asks the nurse how long will antibiotics have to be administered. Which information should the nurse communicate? Parenteral antibiotics for 4 to 8 weeks, then oral antibiotics for 4 to 8 weeks. Treatment of acute osteomyelitis requires administration of high doses of parenteral antibiotics for 4 to 8 weeks, followed by oral antibiotics for another 4 to 8 weeks. The healthcare provider prescribes high-protein, high-fat, low-carbohydrate diet with limited fluids during meals for a client recovering from gastric surgery. The client asks the nurse what the purpose is for this type of diet. Which rationale should be included in the nurse's explanation to this client? It is slow to leave the stomach. This type of diet is slowly digested and is slow to leave the stomach, thereby the possibility of dumping syndrome is reduced as a result of its density from proteins and fats, and the reduction of fluids. The nurse is preparing a client for orthopedic surgery on the left leg and completing a safety checklist before transport to the operating room. Which items should the nurse remove from the client? (Select all that apply.) Nail polish, Hearing aids, Contact lenses, Partial dentures. The removal of nail polish provides a more accurate pulse oximetry readings and evaluation of capillary refill. Hearing aids, contact lenses, and partial dentures are removed to prevent damage, loss or misplacement, or injury during surgery. Ideally, give the client's significant other the contact lenses if they are not the disposable ones, hearing aids and partial dentures once placed in an appropriate labeled container to hold for safe keeping. If no significant other is not able to hold onto the items, then secured them in an appropriate and safe place. Which finding should the nurse report to the healthcare provider for a client with a circumferential extremity burn? Slow capillary refill in the digits with absent distal pulse points. A circumferential burn can form an eschar that results from burn exudate fluid that dries and acts as a tourniquet as fluid shifts occur in the interstitial tissue. As edema increases tissue pressure, blood flow to the distal extremity is compromised, which is manifested by slow capillary refill and absent distal pulses, so the healthcare provider should be notified about any compromised circulation that requires escharotomy. Which findings are within expected parameters of a normal urinalysis for an older adult? (Select all that apply.) A pH of 6.0 is within the normal pH range for urine. Glucosuria and bilirubinuria are abnormal and should be negative upon urinalysis. Normal changes associated with aging include decreased creatinine clearance and decreased concentrating and diluting abilities which influence the normal range of urine specific gravity, 1.001 to 1.035.Although common health problems associated with aging include renal insufficiency, urinary incontinence, urinary tract infection, and enlarged prostate, these are indicative of pathology which should be treated. When planning care for a client with right renal calculi, which nursing diagnosis has the highest priority? Acute pain related to movement of the stone. The nursing diagnosis of the highest priority is "Acute pain related the the renal calculi's movement". A client who is admitted to the emergency department with a possible tension pneumothorax after a motor vehicle collision is having multiple diagnostic tests. Which finding requires immediate action by the nurse? Chest x-ray indicating a mediastinal shift. Immediate action is required for findings of a mediastinal shift, which can precipitate life-threatening cardiovascular collapse as the great cardiac vessels become kinked and compressed due to the tension pneumothorax. A client who returns to the unit after having a percutaneous transluminal coronary angioplasty (PTCA) complains of acute chest pain. What action should the nurse implement next? Give a sublingual nitroglycerin tablet. After a percutaneous transluminal coronary angioplasty (PTCA), a client who experiences acute chest pain may be experiencing cardiac ischemia related to restenosis, stent thrombosis, or acute coronary syndrome involving any coronary artery. The first action is to administer nitroglycerin to dilate the coronary arteries and increase myocardial oxygenation. A nurse is preparing to insert an IV catheter after applying an eutectic mixture of lidocaine and prilocaine (EMLA), a topical anesthetic cream. What action should the nurse take to maximize its therapeutic effect? Leave the cream on the skin for 1 to 2 hours before the procedure. Topical anesthetic creams, such as EMLA, should be applied to the puncture site at least 60 minutes to 2 hours before the insertion of an IV catheter. What is the priority nursing action while caring for a client on a ventilator when an electrical fire occurs in the intensive care unit? Use a bag-valve-mask resuscitator while removing the client from the area. A client on a ventilator should have respirations maintained with a manual bag-valve-mask resuscitator while being moved away from the oxygen wall outlet and fire source. A client is admitted after blunt abdominal injury. Which assessment finding requires immediate action by the nurse? Bluish periumbilical skin discoloration. Immediate action is indicated for intraperitoneal hemorrhage which causes periumbilical discoloration (D) and indicates the presence of a splenic rupture, a life-threatening complication of blunt abdominal injury. (A, B, and C) indicate inflammation of the appendix or gallbladder but do not represent an acute finding as a result of blunt abdominal trauma. The nurse is assessing a client admitted from the emergency room with gastrointestinal bleeding related to peptic ulcer disease (PUD). Which physiological factors can produce ulceration? (Select all that apply.) Vagal stimulation., Decreased duodenal inhibition., Hypersecretion of hydrochloric acid., An increased number of parietal cells. Hypersecretion of gastric juices and an increased number of parietal cells that stimulate secretion are most often the causes of ulceration. Vagal stimulation and decreased duodenal inhibition also increase the secretion of caustic fluids. A client is admitted to the hospital with a traumatic brain injury after his head violently struck a brick wall during a gang fight. Which finding is most important for the nurse to assess further? Serosanguineous nasal drainage. Any nasal discharge following a head injury should be evaluated to determine the presence of cerebral spinal fluid which would indicate a tear in the dura making the client susceptible to meningitis. A male client with a prostatic stent is preparing for discharge. What should the nurse ensure the client understands? The client should not be catheterized through the stent for at least three months. A prostatic stent is a cylinder shape tube that is placed in the urethra to relieve prostatic pressure from an enlarged prostate and improve urine flow. To prevent complications, the client should be cautioned against catheterization through the prostatic stent for three months after stent placement. The nurse is caring for a client who is two days postoperative. Which observation should alert the nurse to call the Rapid Response Team (RRT)? Pulse change from 85 to160 beats/minute lasting more than 10 minutes. The RRT should be called to intervene for a client with an acute life-threatening change, such as a pulse change resulting in tachycardia for a prolonged time in a post-operative client. A client with a recent history of blood in his stools is scheduled for a proctosigmoidoscopy. The nurse should implement which protocols to prepare the client for this procedure? (Select all that apply.) The usual preoperative preparation for proctosigmoidoscopy entails obtaining the client's consent to the procedure, a clear-liquid diet for 24 to 48 hours prior to the procedure, administration of an enema, and fasting on the morning of the procedure. A Korean-American client, who speaks very little English, is being discharged following surgery. Which nurse should the nurse manager assign to provide the discharge instructions for the client? The registered nurse (RN) case-manager for the unit with 1 years’ experience. The RN case-manager is the best qualified nurse to assess and provide discharge educational needs, obtain resources for the client, enhance coordination of care, and prevent fragmentation of care. During the initial outbreak of genital herpes simplex for a female client, what should be the nurse's primary focus in planning care? Promotion of comfort. The initial outbreak of genital herpes simplex in a woman causes severe discomfort. Promotion of comfort is the first priority. A client asks the nurse about the purpose of beginning chemotherapy (CT) because the tumor is still very small. Which information supports the explanation that the nurse should provide? The cell count of the tumor reduces by half with each dose. Initiating chemotherapy while the tumor is small provides a better chance of eradicating all cancer cells because 50% of cancer cells or tumor cells are killed with each dose. The nurse is assessing a client who is bedfast and refuses to turn or move from a supine position. How should the nurse assess the client for possible dependent edema? Compress the flank and upper buttocks. Dependent edema collects in dependent areas, such as the flank and upper buttocks of the client who is persistently flat in bed. By compressing these areas, the nurse can determine if any pitting edema is present. [Show More]
