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. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?

• A. Four medications decrease the risk of a severe allergic reaction.
• B. Four medications reduce the chance that the bacteria will become resistant.
• C. Four medications reduce the risk of adverse reactions.
• D. Four medications decrease the chance of having a positive tuberculin skin test.

Correct answer: B

Rationale: The correct answer is B. When treating tuberculosis, using a combination of medications is crucial to reduce the risk of bacteria developing resistance to any single drug. This approach helps prevent treatment failure and ensures successful treatment outcomes. Choice A is incorrect because the primary purpose of using multiple medications is not related to allergic reactions. Choice C is incorrect as the risk reduction is mainly focused on bacterial resistance rather than adverse reactions. Choice D is not relevant as the purpose of taking multiple medications is not to affect the tuberculin skin test results.

3. While providing teaching to a client with a new prescription for Enalapril, the nurse should instruct the client to report which of the following manifestations as an adverse effect of this medication?

• A. Tremors
• B. Dry cough
• C. Drowsiness
• D. Hyperactivity

Correct answer: B

Rationale: The correct answer is 'B: Dry cough.' Enalapril is an ACE inhibitor known to cause a persistent dry cough as a common adverse effect. This cough should be reported to the healthcare provider for further evaluation, as it may indicate a potential issue with the medication that needs attention to ensure the client's well-being. Tremors (Choice A), drowsiness (Choice C), and hyperactivity (Choice D) are not typically associated with Enalapril use. Therefore, they are incorrect choices for this question.

4. A client who is withdrawing from alcohol has been prescribed Propranolol. Which information should the nurse include in the teaching?

• A. Increases the risk for seizure activity.
• B. Provides a form of aversion therapy.
• C. Decreases cravings.
• D. Results in mild hypertension.

Correct answer: C

Rationale: The correct information the nurse should include in the teaching is that Propranolol decreases cravings for alcohol. Propranolol is used as an adjunct medication during alcohol withdrawal to help reduce the desire for alcohol. Choice A is incorrect as Propranolol does not increase the risk for seizure activity; it can actually be used to prevent alcohol withdrawal seizures. Choice B is also incorrect as Propranolol does not provide aversion therapy. Choice D is incorrect as Propranolol is not known to result in mild hypertension.

5. A client received IV Verapamil to treat supraventricular tachycardia (SVT). The client's pulse rate is now 98/min, and blood pressure is 74/44 mm Hg. The nurse should anticipate a prescription for which of the following IV medications?

• A. Calcium gluconate
• B. Sodium bicarbonate
• C. Potassium chloride
• D. Magnesium sulfate

Correct answer: A

Rationale: In this situation, where the client's blood pressure is significantly lowered due to Verapamil administration, the nurse should anticipate a prescription for Calcium gluconate. Calcium gluconate is used to reverse severe hypotension caused by Verapamil. It should be given slowly intravenously as it counteracts the vasodilation caused by Verapamil, helping to normalize blood pressure levels. Sodium bicarbonate is not indicated for low blood pressure. Potassium chloride and magnesium sulfate are not the appropriate choices to address hypotension caused by Verapamil.
