A client has a new prescription for Lovastatin. Which of the following instructions should the nurse include?

Correct Answer: C

Rationale: In the context of pharmacology and specifically the medication Lovastatin, it is crucial for the nurse to provide accurate instructions to the client. The correct answer, which is option C - Take this medication at bedtime, is based on the pharmacokinetics of Lovastatin. Lovastatin is a statin drug that inhibits cholesterol synthesis in the liver, and its peak effectiveness occurs during nighttime when the body naturally produces cholesterol. Therefore, taking Lovastatin at bedtime maximizes its therapeutic effects. Option A - Take this medication on an empty stomach, is incorrect because Lovastatin can be taken with or without food. It does not need to be specifically taken on an empty stomach for optimal effectiveness. Option B - Take this medication in the morning, is incorrect because, as mentioned earlier, Lovastatin's peak effectiveness aligns with nighttime cholesterol production, making bedtime a more suitable time for administration. Option D - Increase your intake of potassium-rich foods, is unrelated to Lovastatin therapy. Lovastatin does not require an increase in potassium-rich foods for its efficacy or safety. In an educational context, understanding the rationale behind the timing of medication administration is essential for safe and effective pharmacological management. Nurses must have a solid foundation in pharmacokinetics to provide accurate and patient-specific instructions regarding medication administration timings. This knowledge ensures optimal drug effects and patient outcomes.

Correct Answer: A

Rationale: In pharmacology, it is crucial for nurses to understand the potential adverse effects of medications to educate patients effectively. In the case of Spironolactone, a potassium-sparing diuretic, the correct adverse effect to monitor for is hyperkalemia (option A). Spironolactone works by blocking aldosterone receptors, leading to decreased sodium reabsorption and potassium retention. This can result in elevated potassium levels, potentially leading to dangerous cardiac arrhythmias. Options B, C, and D are incorrect because Spironolactone does not typically cause hypoglycemia, hypocalcemia, or hyponatremia. Understanding these incorrect options is essential for the nurse to differentiate between expected and concerning side effects when educating the client about their medication regimen. Educationally, this question reinforces the importance of patient monitoring and education when administering medications that can impact electrolyte balance. Nurses need to be vigilant in teaching patients about signs and symptoms of hyperkalemia and the importance of regular monitoring of lab values while taking Spironolactone to ensure safe and effective therapy.

Correct Answer: C

Rationale: In pharmacology, understanding the administration instructions for medications is crucial to ensure their efficacy and safety. In the case of Levothyroxine, the correct instruction is to take the medication on an empty stomach. This is because Levothyroxine is a thyroid hormone replacement medication that needs to be absorbed consistently and fully to maintain thyroid hormone levels in the body. Taking it on an empty stomach ensures optimal absorption, as food can interfere with its uptake. Option A, taking the medication with food, is incorrect because, as mentioned, food can interfere with the absorption of Levothyroxine. Option B, taking the medication at bedtime, is also incorrect because it is recommended to take Levothyroxine in the morning on an empty stomach to avoid potential interactions with food throughout the day. Option D, taking the medication with antacids, is wrong because antacids can also interfere with the absorption of Levothyroxine, reducing its effectiveness. Educationally, understanding the rationale behind specific medication administration instructions not only ensures the medication's effectiveness but also prevents potential adverse effects. It is essential for nurses to educate clients on the proper administration of medications to promote positive health outcomes and prevent complications.

Correct Answer: C

Rationale: Furosemide is a diuretic that can lead to orthostatic hypotension, causing dizziness and falls. Instructing the client to change positions slowly helps prevent these adverse effects by allowing the body to adjust to postural changes gradually, reducing the risk of significant blood pressure drops upon standing up quickly.

Correct Answer: C

Rationale: In this scenario, the correct answer is option C: Bradycardia. Atenolol is a beta-blocker medication that works by slowing down the heart rate. Therefore, a potential adverse effect of atenolol is bradycardia, which is a slow heart rate. Option A, Tachycardia, is incorrect because atenolol actually works to reduce heart rate, so an increase in heart rate (tachycardia) would not be an expected adverse effect. Option B, Hypoglycemia, is not typically associated with atenolol use. Atenolol can mask some of the symptoms of hypoglycemia, such as tachycardia, but it does not directly cause hypoglycemia. Option D, Hypertension, is also incorrect because atenolol is actually used to treat hypertension by lowering blood pressure, so hypertension would not be an expected adverse effect. From an educational context, it is important for nurses to understand the pharmacological actions of medications to anticipate potential adverse effects. By teaching clients to monitor for signs of bradycardia when taking atenolol, nurses can help ensure patient safety and medication adherence.
