HESI RN CAT Exit Exam

Correct Answer: A

Rationale: The correct answer is A: Avoiding the administration of high levels of oxygen for extended periods. Oxygen toxicity can occur when high levels of oxygen are given for a prolonged period. It is important to monitor and adjust the oxygen levels as needed to prevent toxicity. Choice B is incorrect because administering a sedative to slow the respiratory rate does not directly prevent oxygen toxicity. Choice C is incorrect as removing the nasal cannula during the night can compromise the client's oxygenation. Choice D is incorrect as running oxygen through a hydration source does not prevent oxygen toxicity; instead, it may introduce risks associated with the hydration source.

Correct Answer: D

Rationale: The correct answer is 'D. Breath sounds.' When a client receiving amlodipine develops edema, it is crucial to assess for potential heart failure, a side effect of the medication. Checking breath sounds helps in identifying any signs of pulmonary edema, a severe complication of heart failure. Choices A, B, and C are less relevant in this context. Bladder distention could be associated with urinary issues, serum albumin level with malnutrition or liver disease, and abdominal girth with gastrointestinal problems, none of which directly relate to the potential heart failure induced by amlodipine.

Correct Answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

Correct Answer: B

Rationale: The correct answer is B because a client with lupus erythematosus can be safely transferred to the antepartal unit as this condition does not pose a significant risk to other patients or staff. Choices A, C, and D should not be recommended for transfer to the antepartal unit due to the potential risks they may pose to pregnant women and their unborn babies. Chronic hepatitis B, rubella, and herpes lesions of the vulva can be contagious and harmful in the perinatal setting.

Correct Answer: D

Rationale: The correct instruction for an elderly client taking both an ACE inhibitor and a calcium channel blocker is to change positions slowly. Both medications can lead to orthostatic hypotension, a sudden drop in blood pressure when changing positions, which can increase the risk of falls. Instructing the client to change positions slowly helps prevent falls. Wearing long-sleeved clothing when outdoors does not directly relate to the medication combination. Reporting the onset of a sore throat is important for monitoring potential side effects but is not specific to these medications. While potassium levels should be monitored with ACE inhibitors, eating plenty of potassium-rich foods without guidance can lead to hyperkalemia, a potential side effect of ACE inhibitors.
