HESI EXIT EXAM 4 – QUESTION AND ANSWERS

Document Content and Description Below

A client is receiving furosemide (Lasix) to relieve edema. The nurse should monitor the client for which response to the medication? 1 Retention of sodium ions 2 Negative nitrogen balance Corr... ect3 Excessive loss of potassium ions 4 Increase in the urine specific gravity Furosemide is a potent diuretic used to provide rapid diuresis; it acts in the loop of Henle and causes depletion of electrolytes, such as potassium and sodium. Furosemide inhibits the reabsorption, not retention, of sodium. Furosemide does not affect protein metabolism. With edema, the specific gravity of the fluid more likely will be low. Test-Taking Tip: Pace yourself when taking practice quizzes. Because most nursing exams have specified time limits, you should pace yourself during the practice testing period accordingly. It is helpful to estimate the time that can be spent on each item and still complete the examination in the allotted time. You can obtain this figure by dividing the testing time by the number of items on the test. For example, a 1-hour (60-minute) testing period with 50 items averages 1.2 minutes per question. The NCLEX exam is not a timed test. Both the number of questions and the time to complete the test varies according to each candidate's performance. However, if the test taker uses the maximum of 5 hours to answer the maximum of 265 questions, each question equals 1.3 minutes. 80%of students nationwide answered this question correctly.

What should the nurse do if the specimen cannot be sent immediately to the laboratory? 1 Take no special action. Correct2 Refrigerate the specimen. 3 Store it in the dirty utility room and send it later. 4 Discard the specimen and collect another specimen later. Refrigeration retards the growth of bacteria and may preserve the specimen for several hours. Growth of bacteria will alter the pH and the glucose and protein levels in the urine; it must be refrigerated to retard growth. Discarding the specimen and collecting another specimen later represents an unnecessary waste of time, effort, and money. Test-Taking Tip: Being emotionally prepared for an examination is key to your success. Proper use of this text over an extended period of time ensures your understanding of the mechanics of the examination and increases your confidence about your nursing knowledge. Your lifelong dream of becoming a nurse is now within your reach! You are excited, yet anxious. This feeling is normal. A little anxiety can be good because it increases awareness of reality; but excessive anxiety has the opposite effect, acting as a barrier and keeping you from reaching your goal. Your attitude about yourself and your goals will help keep you focused, adding to your strength and inner conviction to achieve success. 83%of students nationwide answered this question correctly.

What action should the nurse take? 1 Alert the cardiac arrest team 2 Call the laboratory to repeat the test Correct3 Take vital signs and notify the primary health care provider 4 Obtain an ECG strip and obtain an antiarrhythmic medication Vital signs monitor the cardiopulmonary status; the health care provider must treat this hyperkalemia to prevent cardiac dysrhythmias. The cardiac arrest team responds to a cardiac arrest; there is no sign of arrest in this client. A repeat laboratory test will take time and probably reaffirm the original results; the client needs medical attention. Obtaining an ECG strip and having an antiarrhythmic available are correct interventions if available, but the priority is medical attention and the health care provider should be notified immediately. 82%of students nationwide answered this question correctly.
