Nursing Elites

1. When taking Digoxin, low levels of what can cause toxicity?

• A. Potassium
• B. Calcium
• C. Sodium
• D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

2. When administering IV Acyclovir to a client with Varicella, what action should the nurse take?

• A. Administer a stool softener
• B. Decrease fluid intake following infusion
• C. Infuse Acyclovir over 1 hr
• D. Monitor for hypotension

Correct answer: C

Rationale: When administering IV Acyclovir to a client with Varicella, the nurse should infuse the medication over at least 1 hour to prevent nephrotoxicity. Rapid infusion can lead to adverse effects such as renal damage. Therefore, it is crucial to follow the recommended infusion rate to ensure the client's safety and well-being. Choice A is incorrect as stool softeners are not indicated in this situation. Choice B is incorrect because fluid intake should be maintained or increased to prevent dehydration and support kidney function. Choice D is incorrect as monitoring for hypotension is not specifically related to the administration of IV Acyclovir in Varicella.

3. A client with heart failure is receiving instructions about laxative use. The client should be advised to avoid which of the following laxatives?

• A. Sodium phosphate
• B. Psyllium
• C. Bisacodyl
• D. Polyethylene glycol

Correct answer: A

Rationale: Clients with heart failure often have sodium restrictions. Sodium phosphate can lead to fluid retention due to sodium absorption, which is harmful for individuals with heart failure. Therefore, it should be avoided in this population to prevent exacerbating fluid overload. Psyllium, Bisacodyl, and Polyethylene glycol are safer options for individuals with heart failure as they do not pose the risk of exacerbating fluid overload through sodium retention.

4. A client has been prescribed Valsartan. Which of the following adverse effects should the nurse monitor?

• A. Hyperkalemia
• B. Hypoglycemia
• C. Bradycardia
• D. Hypercalcemia

Correct answer: A

Rationale: Corrected Rationale: Valsartan is an angiotensin II receptor blocker (ARB) that can lead to hyperkalemia by inhibiting the action of aldosterone. Hyperkalemia is a potential adverse effect, making it essential for the nurse to closely monitor the client's potassium levels to prevent complications such as cardiac arrhythmias. Incorrect Options Rationale: - Option B, Hypoglycemia, is not a common adverse effect of Valsartan. - Option C, Bradycardia, is not typically associated with Valsartan use. - Option D, Hypercalcemia, is not a known adverse effect of Valsartan; instead, Valsartan can lead to hyperkalemia.

5. A client receives a new prescription for NRTIs for HIV treatment. Which statement should the nurse include during teaching about these medications?

• A. These medications work by inhibiting enzymes to prevent HIV replication.
• B. These medications work by preventing protein synthesis within the HIV cell.
• C. These medications work by weakening the cell wall of the HIV virus.
• D. These medications work by blocking HIV entry into cells.

Correct answer: A

Rationale: NRTIs inhibit the enzyme reverse transcriptase, essential for HIV replication. By preventing this process, viral replication is hindered, ultimately reducing the viral load in the body. Option A correctly explains the mechanism of action of NRTIs in treating HIV infection. Choices B, C, and D describe mechanisms of action that do not align with how NRTIs work in HIV treatment. B is incorrect because NRTIs do not target protein synthesis within the HIV cell. C is incorrect as NRTIs do not affect the cell wall of the HIV virus. D is incorrect because NRTIs do not block HIV entry into cells.
