Correct Answer: B

Rationale: Corrected Rationale: When a client is receiving potassium-sparing diuretics, the healthcare professional should monitor for hyperkalemia. Potassium-sparing diuretics can cause potassium retention, leading to elevated potassium levels in the blood. Monitoring potassium levels is crucial to prevent hyperkalemia-related complications such as cardiac arrhythmias. Choices A, C, and D are incorrect because potassium-sparing diuretics typically do not cause hypokalemia, hypoglycemia, or hyponatremia.

Correct Answer: B

Rationale: When educating a client about levothyroxine, it is important to emphasize the need to monitor for signs of hyperthyroidism. Levothyroxine should be taken on an empty stomach, preferably in the morning, to maximize its absorption. Choice A is incorrect as it should not be taken with food. Choice C is incorrect as levothyroxine is not a pain reliever. Choice D is incorrect as levothyroxine is usually taken in the morning.

Correct Answer: A

Rationale: Corrected Rationale: Digitalis toxicity is a serious complication of digoxin therapy, particularly in older adults. Early symptoms include anorexia, nausea, and generalized weakness. Anorexia and weakness are common indicators of digitalis toxicity. Hyperactivity, hunger, tachycardia, increased urination, polyphagia, and polydipsia are not typical signs of digitalis toxicity. Monitoring for anorexia and weakness can help detect toxicity early and prevent life-threatening arrhythmias.

Correct Answer: D

Rationale: The correct answer is D: All of the above. Addiction is influenced by various factors, including low self-esteem, family history of addiction, and specific personality traits. Low self-esteem can lead individuals to seek solace in substances, a family history of addiction can increase the likelihood of developing addictive behaviors due to genetic and environmental factors, and certain personality disorders may contribute to addictive tendencies. Therefore, all the factors listed in choices A, B, and C can play a role in the development of addictive disorders. Choices A, B, and C are incorrect because addictive disorders are multifactorial, and it is essential to consider a combination of influences rather than isolating a single factor.

Correct Answer: A

Rationale: The correct answer is A) Liver function. Duloxetine can affect liver function, making it crucial for the nurse to monitor liver function tests. Monitoring serum electrolytes (choice B), blood glucose (choice C), or potassium levels (choice D) is not directly associated with duloxetine use and would not be the priority in this case.
