Correct Answer: C

Rationale: In a client taking levothyroxine for thyroid hormone replacement, decreased TSH levels indicate that the medication is effective. TSH levels decrease as the thyroid hormone levels are adequately replaced by levothyroxine, signaling a positive response to treatment. Choices A, B, and D are incorrect because weight gain, increased heart rate, and elevated blood pressure are not expected findings indicating the effectiveness of levothyroxine therapy. Weight gain may suggest inadequate dosing, while increased heart rate and elevated blood pressure could indicate over-replacement or side effects of the medication.

Correct Answer: B

Rationale: The correct answer is to instruct the client to monitor their heart rate daily when taking atenolol. Atenolol can lead to bradycardia, a slow heart rate. By monitoring heart rate daily, the client can promptly identify any significant changes and seek medical attention if necessary. This proactive approach enables early detection of potential adverse effects of atenolol, contributing to the client's safety and well-being. Choices A, C, and D are incorrect because taking atenolol at bedtime, increasing potassium-rich foods intake, or avoiding dairy products are not specific instructions related to the potential side effects of atenolol.

Correct Answer: C

Rationale: In a client taking levothyroxine for thyroid hormone replacement, decreased TSH levels indicate that the medication is effective. TSH levels decrease as the thyroid hormone levels are adequately replaced by levothyroxine, signaling a positive response to treatment. Choices A, B, and D are incorrect because weight gain, increased heart rate, and elevated blood pressure are not expected findings indicating the effectiveness of levothyroxine therapy. Weight gain may suggest inadequate dosing, while increased heart rate and elevated blood pressure could indicate over-replacement or side effects of the medication.

Correct Answer: B

Rationale: Tremors are a concerning sign of lithium toxicity that indicate a potential overdose. Tremors can progress to more severe symptoms if not addressed promptly. Reporting tremors promptly allows the provider to assess the client's lithium levels, adjust the dosage, or provide appropriate interventions to prevent further complications. Increased urination, weight gain, and blurred vision are potential side effects of lithium but are not indicative of toxicity or overdose. While they should still be monitored, they are not as urgent as tremors in the context of lithium therapy.

Correct Answer: A

Rationale: The correct answer is A: Dry cough. A dry cough is a common side effect of lisinopril. It is essential to report this to the healthcare provider as it may indicate the need to discontinue the medication to prevent further complications such as angioedema or cough that can persist for weeks to months after stopping the medication. Choice B, hyperkalemia, is not typically associated with lisinopril use; instead, it is a possible side effect of medications like potassium-sparing diuretics. Choice C, elevated blood pressure, would not be a concerning finding as lisinopril is often prescribed to lower blood pressure. Choice D, increased appetite, is not a common side effect of lisinopril and would not typically warrant immediate reporting.
