A nurse is teaching a client who has a new prescription for Hydralazine. Which of the following adverse effects should the nurse instruct the client to monitor?

Correct Answer: A

Rationale: In this scenario, the correct answer is A) Tachycardia. When teaching a client about a new prescription for Hydralazine, a vasodilator used to treat hypertension, it is crucial to highlight potential adverse effects. Hydralazine can cause tachycardia as a common side effect due to its direct vasodilatory effect on arteries, leading to reflex tachycardia as the body compensates for the sudden drop in blood pressure. The incorrect options are B) Hyperglycemia, C) Hyponatremia, and D) Constipation. Hydralazine does not typically impact blood glucose levels, sodium levels, or cause constipation. Therefore, educating the client on monitoring for these specific adverse effects would not be relevant in the context of taking Hydralazine. In an educational context, understanding the rationale behind monitoring specific adverse effects of medications enhances patient safety and promotes effective medication management. Nurses play a vital role in educating clients on medication side effects to empower them to recognize and report any concerning symptoms promptly, ensuring optimal therapeutic outcomes.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Avoid taking this medication with dairy products. Ciprofloxacin is a fluoroquinolone antibiotic that can form chelates with divalent and trivalent cations such as calcium, magnesium, aluminum, and iron found in dairy products, antacids, and multivitamins. These chelates can reduce the absorption of ciprofloxacin, leading to decreased effectiveness of the medication. Option A) Take this medication with meals is incorrect because taking ciprofloxacin with food may delay its absorption, but it is not a critical instruction like avoiding dairy products. Option C) Take this medication at bedtime does not impact the absorption or effectiveness of ciprofloxacin, so it is not a necessary instruction. Option D) Increase your intake of potassium-rich foods is irrelevant to ciprofloxacin therapy and does not play a role in the medication's mechanism of action or potential interactions. Educationally, understanding medication administration instructions is crucial for nurses to ensure the effectiveness of treatment and prevent potential drug interactions. Providing accurate information to clients about medication administration helps promote patient safety and optimal therapeutic outcomes.

Correct Answer: A

Rationale: In the context of pharmacology, the correct instruction for a client prescribed Phenytoin is option A) "Brush and floss your teeth regularly." Phenytoin can cause gingival hyperplasia, a side effect characterized by an overgrowth of gum tissue. By emphasizing good oral hygiene practices, such as regular brushing and flossing, the nurse can help prevent or minimize this side effect. Option B) "Avoid drinking grapefruit juice" is incorrect because grapefruit juice is known to interact with certain medications by inhibiting their metabolism, but this is not a concern with Phenytoin. Option C) "Take this medication with food" is incorrect as Phenytoin is typically recommended to be taken on an empty stomach to enhance absorption. Option D) "Increase your intake of calcium-rich foods" is incorrect as Phenytoin can actually interfere with the absorption of calcium, potentially leading to decreased levels in the body. Educationally, this question highlights the importance of understanding medication-specific instructions and side effects. It underscores the significance of patient education in preventing adverse reactions and promoting medication adherence. Nurses play a crucial role in providing clear and accurate information to patients to ensure safe and effective medication management.

Correct Answer: A

Rationale: In pharmacology, understanding the appropriate instructions for medication administration is crucial for patient safety and efficacy. In the case of Prednisone, which is a corticosteroid, the correct instruction among the options provided is to increase intake of potassium-rich foods (Option A). This is because Prednisone can cause potassium loss in the body, leading to potential complications such as hypokalemia. By increasing potassium-rich foods, the client can help maintain optimal potassium levels and prevent adverse effects. Option B, avoiding consuming grapefruit juice, is not directly related to Prednisone. Grapefruit juice is known to interact with certain medications by affecting their metabolism in the body, but this is not a concern with Prednisone. Option C, taking the medication with food, is a general guideline for many medications to prevent gastrointestinal upset. However, Prednisone can be taken with or without food, so this instruction is not specific to this medication. Option D, decreasing intake of sodium-rich foods, is not directly related to Prednisone either. Prednisone can cause sodium retention in the body, so reducing sodium intake may not be necessary unless the client has specific conditions that require sodium restriction. Educationally, this question highlights the importance of understanding specific medication instructions based on the drug's mechanism of action and potential side effects. It underscores the need for individualized patient education to ensure safe and effective medication use.

Correct Answer: B

Rationale: The correct answer is to avoid drinking grapefruit juice when taking Atorvastatin. Grapefruit juice can interfere with the metabolism of Atorvastatin, leading to increased blood levels of the medication, which can result in a higher risk of adverse effects, such as muscle pain and liver damage. It is important for the client to follow this instruction to ensure the safe and effective use of Atorvastatin.
