HESI RN CAT Exit Exam
1. While assessing a client who is experiencing Cheyne-Stokes respirations, the nurse observes periods of apnea. What action should the nurse implement?
- A. Elevate the head of the client's bed
- B. Auscultate the client's breath sounds
- C. Measure the length of the apneic periods
- D. Suction the client's oropharynx
Correct answer: C
Rationale: When a nurse observes periods of apnea in a client experiencing Cheyne-Stokes respirations, measuring the length of the apneic periods is essential. This action helps in determining the severity of Cheyne-Stokes respirations by providing valuable information about the duration of interrupted breathing cycles. Elevating the head of the client's bed (Choice A) may be beneficial in some respiratory conditions but is not the priority in Cheyne-Stokes respirations. Auscultating the client's breath sounds (Choice B) is a general assessment and may not directly address the issue of apnea in Cheyne-Stokes respirations. Suctioning the client's oropharynx (Choice D) is not the initial intervention for managing Cheyne-Stokes respirations unless secretions are obstructing the airway.
2. A client with urticaria due to environmental allergies is taking diphenhydramine (Benadryl). Which complaint should the nurse identify as a side effect of this OTC medication?
- A. Nausea and indigestion.
- B. Hypersalivation.
- C. Eyelid and facial twitching.
- D. Increased appetite.
Correct answer: A
Rationale: The correct answer is A: Nausea and indigestion. Diphenhydramine, an antihistamine, commonly causes gastrointestinal side effects such as nausea and indigestion. These symptoms are often reported by individuals taking this medication. Choices B, C, and D are incorrect because hypersalivation, eyelid and facial twitching, and increased appetite are not typically associated with diphenhydramine use.
3. A client with a history of peptic ulcer disease is admitted with sudden severe abdominal pain. Which finding indicates the possibility of a perforated ulcer?
- A. Bowel sounds are hyperactive in all quadrants.
- B. Abdomen is soft and nondistended.
- C. The client reports sudden severe abdominal pain.
- D. Blood pressure of 110/70 mm Hg.
Correct answer: C
Rationale: The correct answer is C. Sudden severe abdominal pain is a key clinical manifestation of a perforated ulcer. The sudden onset of severe pain is concerning for a perforation in the ulcer, which can lead to peritonitis if not promptly addressed. Choices A, B, and D are incorrect because hyperactive bowel sounds, a soft and nondistended abdomen, and a blood pressure of 110/70 mm Hg are not specific indicators of a perforated ulcer. Hyperactive bowel sounds may suggest increased gastrointestinal motility, a soft abdomen may not necessarily indicate a perforation, and a blood pressure of 110/70 mm Hg is within normal limits and does not directly relate to a perforated ulcer.
4. Which of the following is a priority intervention for a patient with heart failure?
- A. Administering diuretics.
- B. Administering oxygen.
- C. Administering beta-blockers.
- D. Administering vasodilators.
Correct answer: B
Rationale: Administering oxygen is a priority intervention in heart failure because it helps improve oxygenation, alleviate hypoxemia, and reduce the workload on the heart. Oxygen therapy is crucial in managing acute heart failure exacerbations. While diuretics (Choice A) are commonly used in heart failure to reduce fluid overload, administering oxygen takes precedence due to its immediate impact on oxygen delivery. Beta-blockers (Choice C) and vasodilators (Choice D) are also important in heart failure management, but in the acute setting, ensuring adequate oxygen supply is the priority.
5. The nurse is caring for several patients who are receiving antibiotics. Which order will the nurse question?
- A. Azithromycin (Zithromax) 500 mg IV in 500 mL of fluid
- B. Azithromycin (Zithromax) 500 mg PO once daily
- C. Erythromycin 300 mg IM QID
- D. Erythromycin 300 mg PO QID
Correct answer: C
Rationale: The nurse should question the order for Erythromycin 300 mg IM QID. Erythromycin and other macrolides should not be given intramuscularly because they cause painful tissue irritation. Options A and B are correct routes for Azithromycin, either intravenously or orally. Option D is a correct route for Erythromycin, which is orally.
