NUR 335 Exam 1 Guide Math 1.Basic dosage Desired/Available * Quantity 2.Formula: IV DROP Rate Volume (mL) Time (min) x Drop Factor (gtts/mL) = Y (Flow Rate in gtts/min) Example: Calculate the ... IV flow rate for 1200 mL of NS to be infused in 6 hours. The infusion set is calibrated for a drop factor of 15 gtts/mL. Volume (mL) Time (min) x Drop Factor (gtts/mL) = Y (Flow Rate in gtts/min) Convert 6 hours to minutes.  min ← hr ( x by 60 )  6 hr x 60 = 360 min 1200 mL 360 min x 15 gtts/mL = 50 gtts/min 3. Formula: IV ml rate Ordered Per Hour Have x Volume (mL) = Y (Flow Rate in mL/hr) Example: Give patient 500 mg of dopamine in 250 mL of D5W to infuse at 20 mg/hr. Calculate the flow rate in mL/hr. Ordered Per Hour Have x Volume (mL) = Y (Flow Rate in mL/hr) 20 mg/hr 500 mg x 250 mL = 10 mL/hr Chapter 1 ****The nursing process includes assessment, diagnosis, planning, implementation, and evaluation A nurses number one job is to make sure the patient and their family understands treatment plans and discharge teachingDomains of Nursing Practice for Medical-Surgical Nursing Certification 1. Helping Role 2. Teaching-Coaching Function 3. Diagnostic and Patient Monitoring 4. Effective Management of Rapidly Changing Situations 5. Administering and Monitoring Therapeutic Interventions and Regimens 6. Monitoring and Ensuring the Quality of Healthcare Practices 7. Organizational and Work Role Competencies Steps of Evidence-Based Practice 1. Develop the question. 2. Search and collate the best evidence. 3. Evaluate the quality of the evidence. 4. Integrate evidence into practice. 5. Evaluate outcomes of practice change. 6. Disseminate the evidence. Evaluating Levels of Evidence 1. Level I Evidence from systematic reviews of randomized controlled studies (RCTs) 2. Level II Evidence from at least one RCT 3. Level III Evidence from quasi-experimental studies 4. Level IV Evidence from case-control and cohort studies 5. Level V Evidence from systematic reviews of descriptive or qualitative studies 6. Level VI Evidence from a single descriptive or qualitative study 7. Level VII Evidence from expert individual authorities or committees National Patient Safety Goals 1. Identify patients correctly 2. Improve staff communication 3. Use medicines safely 4. Use alarms safely 5. Prevent infection 6. Identify patient safety risks 7. Prevent mistakes in surgery The SBAR Approach for Effective Communication SBAR is an acronym that correlates to: Situation: Brief statement of the problem or issue being addressed EX: Hello, Dr. Jones. This is Steve, the registered nurse caring for Ms. Sandra Williams in Room 732 on South Wing. I am contacting you because she arrived from the post-anesthesia care unit (PACU) and has not voided in more than 6 hours. Vitals will be here also Background: Data related to the current situation EX: She was admitted to the hospital this morning, and you performed a lumbar laminectomy this morning for a herniated disc at L4–L5.Assessment: Summary of causes, significance, severity of situation EX:Ms. Williams is complaining of inability to void. According to her operative reports, she received 1,500 mL of IV fluid during the surgical procedure and in the PACU, and the indwelling catheter was removed prior to transfer from the PACU 6 hours ago; at the time, she had 800 mL of urine output. She has received an additional 250 mL of IV fluid since arriving on the unit. Recommendation: Specific actions needed to address the situation EX: I recommend that an intermittent catheterization be performed at this time. Interprofessional practice 1. Provides patient centered care 2. Work in interdisciplinary teams 3. Employ evidence-based practice 4. Apply quality improvement 5. Utilize informatics Interprofessional collaboration Partnership between a healthcare team and the client to make decisions around health and social Issues ADPIE Assessment Diagnosis Planning Implementation Evaluating Patient centered care Effective communication skills Empathy Caring Compassion Hospital Consumer Assessment of Healthcare Providers and Systems (H C A H P S) The Joint Commission (T J C) The Beryl Institute ****Treating patients and families with dignity and respect Involving patients and families in decision making Quality and Safety Education for Nurses (Q S E N) Patient-Centered Care Teamwork and Collaboration Evidence-Based Practice (E B P) Quality Improvement (Q I) SafetyInformatics ****In medical surgical nursing your biggest responsibility is to make sure your patient understands an procedure and they understand their discharge teaching ****The nurse has to have empathy, be caring, and have compassion Chapter 15 Use 18g for IV blood products Always make sure you have consent for everything consent is your biggest responsibility (Surgeon gets consent) Make sure patient understands the procedure and everything that follows. Make sure that the patient has no questions (Nurses responsibility) They need to know the doctors name Informed Consent Components include: Consent for procedure itself Name of surgeon to perform surgery Reason intervention will benefit the patient Alternative options to surgery Consent for anesthesia Consent to administer blood products ***Although obtaining consent is not the role of the nurse but that of the provider, it is the nurse’s responsibility to ensure that the patient has all the information needed to make an informed decision about the procedure being offered Obtaining Consent The role of the surgeon is to obtain consent for the procedure. The surgeon is solely responsible for obtaining consent in the presence of the patient and one witness. The role of the preoperative nurse is to clarify information and ensure patient understanding. Nurses correct common misconceptions and ease concerns of the patient, family members, or support persons Advanced Directives Defines patient’s wishes Name a power of attorney SurgeryCorrect patient Correct procedure Correct Surgical Site *** Always remember my right may be your left and your left may be my right she make sure your on the correct side Always assess patients Their medical history is important( always ask about bleeding problems) Make sure patients has understanding of how to use assistant devices incase needed Surgical and anesthesia history Do you have poor healing, any pervious surgeries, negative responds to anesthesia, or any allergies ***If allergies put on alert bracelet Last oral intake Guidelines dependent upon institution and population Full stomach increases risk for aspiration ***A patient who has eaten within 8 hours is at risk of aspiration, the introduction of food particles into the lungs through emesis ***According to recent guidelines for elective procedures, the patient may be advised to be NPO 6 to 8 hours for solid foods and 2 hours for clear fluids. Physical preparations Intravenous line An IV line is inserted during the preoperative admission, typically for the purpose of the administration of anesthesia and fluids during the surgery. An 18-gauge catheter is preferred because this size is required for the administration of all blood products. Bowel and bladder preparation Patients receiving abdominal, intestinal, gynecological, or rectal surgery may be asked to perform a bowel preparation. This may be done by use of an enema or gentle laxatives that the patient self-administers at home the night before the procedure. The nurse should confirm and document that this preparation has been performed. Patients scheduled for abdominal, gynecological, or long procedures may also require the insertion of an indwelling catheter to drain urine. This will keep the bladder empty during a procedure, preventing injury to the bladder. It also allows the surgical team to monitor output in the operating room and PACU. Skin preparation Prior to surgery, skin preparation is done to help prevent infection at the surgical site. Patients may be instructed to shower and wash with Betadine or hexachlorophene soap prior to admission. A surgical shave may be necessary depending on the patient’s skin type and the location of the incision. If a shave is appropriate, the nurse uses a sterile electric clipper. A razor is not recommended because of the risk of infection caused by small nicks in the skin that may occur with a razor. Medications Preoperative medications may be required. Patients with preoperative anxiety may be prescribed a benzodiazepine such as midazolam HCl, diazepam, or lorazepam. Antiemetics such asmetoclopramide HCl or ondansetron HCl may be used preoperatively if a patient has a history of nausea and vomiting due to anesthesia. Medications You need to know if the patient takes any medications or herbal medications 3’G’s Ginger.
