HESI Medical Surgical Specialty Exam
1. A nursing assistant is measuring the blood pressure (BP) of a hypertensive client while a nurse observes. Which action on the part of the assistant would interfere with accurate measurement and prompt the nurse to intervene? Select all that apply.
- A. Measuring the BP after the client has sat quietly for 5 minutes
- B. Having the client sit with the arm bared and supported at heart level
- C. Using a cuff with a rubber bladder that encircles less than 80% of the limb
- D. Measuring the BP after the client reports that he just drank a cup of coffee
Correct answer: C
Rationale: To ensure accurate blood pressure (BP) measurement, the cuff used should have a rubber bladder that encircles at least 80% of the limb being measured. This ensures proper compression and accurate readings. Choices A and B are correct practices as it is recommended to measure BP after the client has sat quietly for 5 minutes and to have the client sit with the arm bared and supported at heart level. Choice D is also a correct reason for intervention as the client should not have consumed caffeine or smoked tobacco within 30 minutes before BP measurement, as it can affect the accuracy of the reading.
2. A client who is receiving chemotherapy asks the nurse, 'Why is so much of my hair falling out each day?' Which response by the nurse best explains the reason for alopecia?
- A. 'Chemotherapy affects the cells of the body that grow rapidly, both normal and malignant.'
- B. 'Alopecia is a common side effect you will experience during long-term steroid therapy.'
- C. 'Your hair will grow back completely after your course of chemotherapy is completed.'
- D. 'The chemotherapy causes permanent alterations in your hair follicles that lead to hair loss.'
Correct answer: A
Rationale: The correct answer is A: 'Chemotherapy affects the cells of the body that grow rapidly, both normal and malignant.' Chemotherapy targets rapidly dividing cells, which include not only cancer cells but also healthy cells like those in hair follicles. This leads to alopecia (hair loss) as a common side effect. Choice B is incorrect as alopecia is primarily associated with chemotherapy and not long-term steroid therapy. Choice C is incorrect because while hair may grow back after chemotherapy, it may not always be to the same extent or thickness. Choice D is incorrect as chemotherapy-induced hair loss is often temporary and reversible, not permanent alterations in hair follicles.
3. A client with acute kidney injury (AKI) weighing 50kg and having a potassium level of 6.7mEq/L (6.7mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?
- A. Calcium acetate, one tablet by mouth
- B. Sodium polystyrene sulfonate, 15 grams by mouth
- C. Epoetin Alfa, recombinant, 2,500 units subcutaneously
- D. Sevelamer, one tablet by mouth
Correct answer: B
Rationale: In a client with acute kidney injury (AKI) and hyperkalemia, the priority intervention is to lower the potassium level swiftly. Sodium polystyrene sulfonate is a medication used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, reducing the overall potassium levels. Calcium acetate, epoetin alfa, and sevelamer are not indicated for the immediate reduction of potassium levels in hyperkalemia. Calcium acetate is used to control phosphate levels, epoetin alfa is a medication to treat anemia by stimulating red blood cell production, and sevelamer is a phosphate binder used in chronic kidney disease to reduce phosphate levels.
4. A nurse is conducting an assessment of a client who underwent thoracentesis of the right side of the chest 3 hours ago. Which findings does the nurse report to the physician? Select all that apply.
- A. Unequal chest expansion
- B. Pulse rate of 82 beats/min
- C. Respiratory rate of 22 breaths/min
- D. Diminished breath sounds in the right lung
Correct answer: A
Rationale: After thoracentesis, the nurse should assess the client for signs of pneumothorax, which include increased respiratory rate, dyspnea, retractions, unequal chest expansion, diminished breath sounds, and cyanosis. Unequal chest expansion is a key sign of pneumothorax due to the accumulation of air in the pleural space, causing the affected lung to collapse partially. Pulse rate and respiratory rate within normal ranges, like in choices B and C, are not the priority findings to report in this situation. Diminished breath sounds in the right lung could be expected after thoracentesis and may not necessarily indicate a complication like pneumothorax, making choice D less urgent to report.
5. A female patient who is allergic to penicillin will begin taking an antibiotic to treat a lower respiratory tract infection. The patient tells the nurse that she almost always develops a vaginal yeast infection when she takes antibiotics and that she will take fluconazole (Diflucan) with the antibiotic being prescribed. Which macrolide should the nurse question for this patient?
- A. Azithromycin (Zithromax)
- B. Clarithromycin (Biaxin)
- C. Erythromycin (E-Mycin)
- D. Fidaxomicin (Dificid)
Correct answer: C
Rationale: The nurse should question the prescription of erythromycin for this patient. When erythromycin is given concurrently with fluconazole, erythromycin blood concentration and the risk of sudden cardiac death increase. Therefore, it is not recommended to use erythromycin in combination with fluconazole for this patient. Azithromycin, clarithromycin, and fidaxomicin are alternative macrolide antibiotics that can be considered for this patient without the same risk of interactions when used with fluconazole.
