Nursing Elites

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. When teaching a client who has a new prescription for Ciprofloxacin, which of the following instructions should the nurse include?

• A. Take this medication with an antacid.
• B. Avoid direct sunlight.
• C. Increase your intake of dairy products.
• D. Expect urine to turn orange.

Correct answer: B

Rationale: The correct instruction for a client prescribed Ciprofloxacin is to avoid direct sunlight. Ciprofloxacin can cause photosensitivity, increasing the risk of sunburn. Clients should be advised to avoid direct sunlight and wear protective clothing, including hats and sunglasses when going outdoors to prevent skin damage. Choices A, C, and D are incorrect. Taking Ciprofloxacin with an antacid can reduce its absorption, so they should not be taken together. Increasing dairy product intake is not necessary or relevant to taking Ciprofloxacin. While Ciprofloxacin can discolor urine, turning it orange, this is not a critical side effect that requires specific instructions for the client.

3. What is the pharmacological action of metformin?

• A. Blocks stimulation of beta1 and beta2.
• B. Blocks vasoconstriction and aldosterone.
• C. Acts at many levels in the CNS to produce an anxiolytic effect.
• D. Decreases hepatic glucose production.

Correct answer: D

Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.

4. A nurse is caring for a client in an outpatient facility who has been taking Acarbose for type 2 Diabetes Mellitus. Which of the following laboratory tests should the nurse plan to monitor?

• A. WBC
• B. Serum potassium
• C. Platelet count
• D. Liver function test

Correct answer: D

Rationale: The correct answer is D, Liver function test. Acarbose can cause liver toxicity when taken long-term. Monitoring liver function tests periodically is essential to assess for any potential liver damage. Choices A, B, and C are incorrect because Acarbose does not directly impact white blood cell count, serum potassium levels, or platelet count.

5. A healthcare professional is reviewing the laboratory results of a client taking Warfarin for atrial fibrillation. Which of the following findings should the professional report to the provider immediately?

• A. INR of 4.0
• B. Potassium level of 4.5 mEq/L
• C. Creatinine level of 1.0 mg/dL
• D. BUN of 18 mg/dL

Correct answer: A

Rationale: An INR of 4.0 indicates that the client's blood is clotting too slowly, increasing the risk of bleeding. This level is above the therapeutic range for a client on Warfarin therapy. Therefore, the healthcare professional should notify the provider immediately to prevent potential bleeding complications. The other laboratory values are within normal limits and do not pose an immediate risk to the client's health while on Warfarin therapy.
