Nursing Elites

1. Which of the following is the primary site of activity for the drug Warfarin?

• A. Kidney
• B. Liver
• C. Blood
• D. Heart

Correct answer: B

Rationale: Warfarin primarily affects the liver where it inhibits the synthesis of clotting factors.

2. A client has been prescribed an ACE Inhibitor for hypertension. Which of the following instructions should be included by the healthcare provider?

• A. Avoid salt substitutes.
• B. Take this medication at bedtime.
• C. Avoid foods high in potassium.
• D. Limit your fluid intake.

Correct answer: A

Rationale: The correct answer is to 'Avoid salt substitutes.' ACE Inhibitors can increase potassium levels, so clients should avoid salt substitutes that contain potassium to prevent hyperkalemia, which is a potential side effect of ACE Inhibitors. Choice B 'Take this medication at bedtime' is incorrect as ACE Inhibitors are usually taken in the morning to avoid nocturnal diuresis. Choice C 'Avoid foods high in potassium' is incorrect because although ACE Inhibitors can increase potassium levels, clients are generally encouraged to consume potassium-rich foods in moderation unless contraindicated. Choice D 'Limit your fluid intake' is also incorrect as ACE Inhibitors do not typically require fluid restrictions unless specified by a healthcare provider for other reasons.

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

• A. Take this medication with food.
• B. Avoid taking aspirin while on this medication.
• C. Avoid eating foods high in potassium.
• D. Take this medication at bedtime.

Correct answer: B

Rationale: The correct answer is B: 'Avoid taking aspirin while on this medication.' Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Aspirin and other NSAIDs also affect platelet function and can further increase the risk of bleeding when combined with Clopidogrel. Therefore, it is important for the client to avoid taking aspirin while on this medication to reduce the risk of excessive bleeding. Choices A, C, and D are incorrect because there is no specific requirement to take Clopidogrel with food, avoid foods high in potassium, or take it at bedtime. The key instruction here is to avoid aspirin to prevent potential bleeding complications.

4. 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.

5. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?

• A. 125 mL/hr
• B. 100 mL/hr
• C. 150 mL/hr
• D. 200 mL/hr

Correct answer: A

Rationale: To calculate the flow rate, divide the total volume by the total time: 750 mL / 6 hr = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse D5W 750 mL over 6 hours. Choice B (100 mL/hr) is incorrect because it does not accurately divide the total volume by the total time. Choice C (150 mL/hr) and Choice D (200 mL/hr) are incorrect as they are not the correct flow rates needed to infuse the D5W solution over the specified time period.
