1. When does regular insulin typically peak?

• A. 30 minutes to 2 ½ hours
• B. 1 to 3 hours
• C. 6 to 14 hours
• D. 1 to 5 hours

Correct answer: D

Rationale: Regular insulin usually peaks around 1 to 5 hours after administration. This peak time frame is important to consider when managing blood glucose levels and timing meals to coincide with insulin activity. Choice A, '30 minutes to 2 ½ hours,' is incorrect because regular insulin typically peaks later. Choice B, '1 to 3 hours,' is not the most accurate as the peak for regular insulin can extend beyond 3 hours. Choice C, '6 to 14 hours,' is incorrect as this timeframe is more indicative of long-acting insulins, not regular insulin.

2. A client has a new prescription for Warfarin for atrial fibrillation. Which of the following findings should the nurse report to the provider immediately?

• A. INR of 4.0
• B. Potassium level of 4.5 mEq/L
• C. Sodium level of 140 mEq/L
• D. Creatinine level of 1.0 mg/dL

Correct answer: A

Rationale: An INR of 4.0 is above the therapeutic range for a client on Warfarin, indicating an increased risk of bleeding. This finding requires immediate reporting to the provider for appropriate intervention to prevent complications associated with excessive anticoagulation. Potassium, sodium, and creatinine levels are within normal ranges and are not directly related to the risk of bleeding in a client on Warfarin therapy.

3. When caring for a client prescribed Digoxin, which of the following laboratory values should the nurse monitor to assess for potential toxicity?

• A. Sodium
• B. Potassium
• C. Magnesium
• D. Calcium

Correct answer: B

Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin. Sodium, magnesium, and calcium levels are not directly associated with Digoxin toxicity; hence, they are not the primary focus for monitoring in this case.

4. A healthcare professional is preparing to administer Enoxaparin to a client. Which of the following actions should the healthcare professional take?

• A. Administer the medication orally.
• B. Massage the injection site after administration.
• C. Insert the needle at a 45- to 90-degree angle.
• D. Aspirate before injecting the medication.

Correct answer: C

Rationale: Enoxaparin should be administered subcutaneously at a 45- to 90-degree angle. This angle ensures proper delivery of the medication. Massaging the injection site should be avoided to prevent bruising and possible tissue damage. Aspiration is not required for subcutaneous injections like Enoxaparin. Therefore, the correct action for administering Enoxaparin is to insert the needle at a 45- to 90-degree angle.

5. When educating a client prescribed Rifampin, which instruction should the nurse provide?

• A. Expect orange discoloration of urine.
• B. Take the medication with food.
• C. Increase your intake of dairy products.
• D. Discontinue the medication if you experience itching.

Correct answer: A

Rationale: The correct instruction for a client prescribed Rifampin is to expect orange discoloration of urine. Rifampin is known to cause harmless discoloration of bodily fluids, including urine, which is a common side effect of this medication. It is important for the nurse to educate the client about this expected side effect to prevent unnecessary concern or discontinuation of the medication. Choices B, C, and D are incorrect because Rifampin does not require specific dietary considerations like taking it with food or increasing dairy intake. Furthermore, itching is not a common side effect that would necessitate immediate discontinuation of Rifampin.
