1. 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.

2. A client has a new prescription for Furosemide. Which of the following dietary instructions should the nurse provide?

• A. Increase your intake of bananas and oranges.
• B. Limit your intake of calcium-rich foods.
• C. Avoid drinking milk.
• D. Increase your intake of green, leafy vegetables.

Correct answer: A

Rationale: The correct answer is A: 'Increase your intake of bananas and oranges.' Furosemide, a loop diuretic, can cause potassium loss leading to hypokalemia. To prevent this, clients should increase their intake of potassium-rich foods, such as bananas and oranges, to replenish potassium levels. Choices B, C, and D are incorrect because limiting calcium-rich foods or avoiding milk is not necessary with Furosemide, and increasing intake of green, leafy vegetables does not specifically address the potential potassium loss associated with this medication.

3. Which of the following is not a side effect of loop diuretics?

• A. Alkalosis
• B. Nausea
• C. Hypotension
• D. Potassium deficits

Correct answer: B

Rationale: Nausea is not commonly associated with loop diuretics. Loop diuretics are known to cause electrolyte imbalances such as potassium deficits, metabolic alkalosis, and hypotension due to excessive fluid loss. Nausea is not a typical side effect of loop diuretics.

4. When teaching a client with a new prescription for Furosemide, which instruction should the nurse include?

• A. Take this medication at bedtime.
• B. Avoid eating foods high in potassium.
• C. Change positions slowly.
• D. Take this medication with meals.

Correct answer: C

Rationale: The correct instruction for a client with a new prescription for Furosemide is to change positions slowly. Furosemide is a diuretic that can lead to orthostatic hypotension, causing dizziness and increasing the risk of falls. By advising the client to change positions slowly, the nurse helps prevent these potential adverse effects. Choices A, B, and D are incorrect. Taking Furosemide at bedtime (Choice A) is not necessary as it can be taken at any time of the day. Avoiding foods high in potassium (Choice B) is more relevant for clients taking potassium-sparing diuretics. Taking Furosemide with meals (Choice D) may lead to increased diuretic effects and frequent urination.

5. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?

• A. Use a blood pressure cuff to distend the veins.
• B. Select the antecubital area to insert the IV catheter.
• C. Distend the veins by using a blood pressure cuff.
• D. Direct the client to lower his arm below his heart.

Correct answer: C

Rationale: The correct answer is C. The healthcare professional should distend the veins using a blood pressure cuff to make the veins more visible and accessible for IV catheter insertion. This technique helps reduce the risk of overfilling the vein, which can lead to complications such as hematoma formation. Choices A, B, and D are incorrect because while selecting the antecubital area is often appropriate for IV insertion in adults, the key action in this scenario is to distend the veins using a blood pressure cuff to facilitate the procedure.
