Nursing Elites

1. The client asks the nurse about common side effects of calcium channel blockers. What should the nurse include in client teaching?

• A. Headache
• B. Constipation
• C. Epistaxis
• D. Dysuria

Correct answer: A

Rationale: One of the common side effects of calcium channel blockers is a headache. This is important information for the nurse to include in client teaching as it helps the client understand potential adverse effects of the medication. Constipation, epistaxis, and dysuria are not typically associated with calcium channel blockers.

2. A client has a new prescription for Nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. Take one tablet every 15 minutes until pain is relieved.
• B. Take one tablet every 5 minutes, up to three doses.
• C. Take one tablet at bedtime.
• D. Take one tablet on an empty stomach.

Correct answer: B

Rationale: The correct administration of Nitroglycerin sublingual tablets involves taking one tablet at the onset of chest pain and repeating every 5 minutes for up to three doses. This protocol helps in managing angina episodes effectively. Choice A suggests taking a tablet every 15 minutes until pain relief, which may delay appropriate intervention. Choice C, taking a tablet at bedtime, is not suitable for immediate relief during angina attacks. Choice D, taking a tablet on an empty stomach, is unrelated to the correct administration of Nitroglycerin sublingual tablets.

3. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

• A. Spironolactone
• B. Furosemide
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.

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

• A. Take this medication at bedtime.
• B. Monitor for signs of hyperglycemia.
• C. Avoid drinking grapefruit juice.
• D. Increase your intake of potassium-rich foods.

Correct answer: C

Rationale: The correct instruction for a client prescribed Verapamil is to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Verapamil, leading to increased blood levels of the medication. This can result in a higher risk of adverse effects, such as hypotension and bradycardia. Therefore, it is essential for the client to avoid grapefruit juice while taking Verapamil to prevent potential complications. Choices A, B, and D are incorrect because taking Verapamil at bedtime, monitoring for signs of hyperglycemia, and increasing potassium-rich foods intake are not specific instructions related to Verapamil therapy and do not address the potential interaction with grapefruit juice.

5. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hours. The available heparin injection is 20,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.8 mL
• B. 0.75 mL
• C. 0.5 mL
• D. 1 mL

Correct answer: A

Rationale: To calculate the volume to administer, use the formula: Desired dose / Concentration = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL. Since the volume needs to be rounded up to the nearest tenth, the correct answer is 0.8 mL. Choice B (0.75 mL) is incorrect because it does not account for rounding up the volume. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the precise calculation based on the given concentration and desired dose.
