Nursing Elites

1. A client with chronic renal failure is receiving sodium polystyrene sulfonate (Kayexalate). The nurse should monitor the client for which of the following?

• A. Hyponatremia.
• B. Hypokalemia.
• C. Hyperkalemia.
• D. Hypocalcemia.

Correct answer: C

Rationale: Correct Answer: The correct answer is C, 'Hyperkalemia.' Sodium polystyrene sulfonate (Kayexalate) is a medication used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Therefore, the nurse should monitor the client for changes in potassium levels to assess the effectiveness of the medication and prevent potential complications related to hyperkalemia. Choice A, 'Hyponatremia,' is incorrect as Kayexalate does not primarily affect sodium levels. Choice B, 'Hypokalemia,' is incorrect as Kayexalate is used to treat high potassium levels, not low. Choice D, 'Hypocalcemia,' is incorrect as Kayexalate does not directly impact calcium levels.

2. Four days following an abdominal aortic aneurysm repair, the client is exhibiting edema of both lower extremities, and pedal pulses are not palpable. Which action should the nurse implement first?

• A. Elevate extremities on pillows
• B. Evaluate edema for pitting
• C. Assess pulses with a vascular Doppler
• D. Wrap the feet with warmed blankets

Correct answer: C

Rationale: In this scenario, the priority action for the nurse is to assess pulses with a vascular Doppler. The absence of palpable pedal pulses following an abdominal aortic aneurysm repair raises concerns about compromised blood flow, which could lead to serious complications like ischemia or thrombosis. Evaluating and confirming the presence or absence of pulses is crucial to guide further interventions. Elevating extremities on pillows (Choice A) may be beneficial for managing edema, but it is not the immediate priority when pulses are not palpable. Evaluating edema for pitting (Choice B) can provide additional information about fluid status but does not address the primary concern of absent pulses. Wrapping the feet with warmed blankets (Choice D) is not appropriate in this situation and may not address the underlying vascular issue.

3. A male client expresses concern about how a hypophysectomy will affect his sexual function. Which of the following statements provides the most accurate information about the physiologic effects of hypophysectomy?

• A. Removing the source of excess hormone should restore the client's libido, erectile function, and fertility.
• B. Potency will be restored, but the client will remain infertile.
• C. Fertility will be restored, but impotence and decreased libido will persist.
• D. Exogenous hormones will be needed to restore erectile function after the adenoma is removed.

Correct answer: A

Rationale: Choice A is the most accurate statement regarding the physiologic effects of hypophysectomy on sexual function. The client's sexual problems are directly related to excessive hormone levels. Removing the source of excess hormone secretion through hypophysectomy should allow the client to return to a normal physiologic pattern, which includes restoring libido, erectile function, and fertility. Choices B, C, and D are incorrect. Choice B incorrectly states that the client will remain infertile, which is not necessarily true after a hypophysectomy. Choice C inaccurately suggests that fertility will be restored while impotence and decreased libido will persist, which is not aligned with the expected outcomes of hypophysectomy. Choice D is incorrect because exogenous hormones are typically not needed to restore erectile function after the adenoma is removed; rather, the removal of the source of excessive hormone secretion should address the sexual function concerns.

4. The patient is receiving a high dose of tetracycline (Sumycin). Which laboratory values should the nurse monitor while caring for this patient?

• A. Blood urea nitrogen (BUN) and creatinine levels
• B. Complete blood counts
• C. Electrolytes
• D. Liver enzyme levels

Correct answer: A

Rationale: High doses of tetracyclines can lead to nephrotoxicity, especially when given along with other nephrotoxic drugs. Renal function tests, such as monitoring blood urea nitrogen (BUN) and creatinine levels, should be performed to assess for nephrotoxicity. Monitoring complete blood counts (choice B) is not directly related to tetracycline therapy. Checking electrolytes (choice C) is important but not the priority when monitoring for tetracycline-induced nephrotoxicity. Monitoring liver enzyme levels (choice D) is not typically indicated in the context of tetracycline therapy.

5. A healthcare professional is monitoring the respiratory status of a client who has just undergone surgery and is wearing a pulse oximeter. Which of the following coexisting problems is cause for the healthcare professional to suspect that the oxygen saturation readings are not entirely accurate?

• A. Infection
• B. Hypertension
• C. Low blood pressure
• D. Loss of cough reflex

Correct answer: C

Rationale: Low blood pressure (hypotension), shock, and the use of peripheral vasoconstricting medications can lead to inaccurate pulse oximetry readings due to impaired peripheral perfusion. Hypertension and infection are not typically associated with inaccurate pulse oximetry readings, while the loss of cough reflex does not directly affect oxygen saturation readings.
