A healthcare provider is assessing a client who is taking levothyroxine. The healthcare provider should recognize that which of the following findings is a manifestation of levothyroxine overdose?

Correct Answer: A

Rationale: The correct answer is A: Insomnia. Levothyroxine is a thyroid hormone replacement medication used to treat hypothyroidism. An overdose of levothyroxine can lead to hyperthyroidism symptoms, such as insomnia. This occurs due to an excess of thyroid hormone in the body, which can increase metabolism and disrupt sleep patterns. The other choices (B: Constipation, C: Drowsiness, D: Hypoactive deep-tendon reflexes) are not typical manifestations of a levothyroxine overdose. Constipation and drowsiness are more commonly associated with hypothyroidism, the condition being treated with levothyroxine. Hypoactive deep-tendon reflexes are not a typical symptom of either hypothyroidism or hyperthyroidism.

Correct Answer: D

Rationale: The correct answer is D: Congestion. ACE Inhibitors like Captopril do not typically cause congestion as a side effect. The main reason is that ACE inhibitors work by dilating blood vessels, which helps reduce blood pressure and improve blood flow. Congestion is more commonly associated with conditions like allergies or upper respiratory infections. A: Rash - Possible side effect of ACE inhibitors, but not specific to Captopril. B: Angioedema - Rare but serious side effect of ACE inhibitors, including Captopril. C: Cough - Common side effect of ACE inhibitors due to increased bradykinin levels.

Correct Answer: D

Rationale: The correct answer is D: Sexual dysfunction. Nifedipine is a calcium channel blocker that primarily causes vasodilation by relaxing blood vessels. Sexual dysfunction is not a common side effect associated with Nifedipine use. Nausea, flushed appearance, and vertigo are potential side effects of Nifedipine due to its mechanism of action on the cardiovascular system. Therefore, D is the correct choice as it does not align with the expected side effects of Nifedipine.

Correct Answer: A

Rationale: The correct answer is A: Hypertension is not a side effect of Sympathoplegics (Clonidine). Sympathoplegics are medications that inhibit the sympathetic nervous system, leading to decreased heart rate and blood pressure. Therefore, hypertension is not a common side effect. Choices B, C, and D are incorrect because difficulty breathing, dry oral cavity, and lethargic behavior are potential side effects of Sympathoplegics due to their central nervous system depressant effects.

Correct Answer: B

Rationale: The correct answer is B: Nausea. Loop diuretics like furosemide work by inhibiting the reabsorption of sodium and water in the loop of Henle in the kidneys. This mechanism can lead to electrolyte imbalances, such as potassium deficits (choice D), and volume depletion, resulting in hypotension (choice C). Loop diuretics can also cause metabolic alkalosis (choice A) due to loss of hydrogen ions. Nausea, however, is not a common side effect of loop diuretics. Therefore, choice B is not a side effect of loop diuretics, making it the correct answer.
