Nursing Elites

1. What is the antidote for Warfarin?

• A. Naloxone
• B. Vitamin K
• C. Glucagon
• D. Vitamin B

Correct answer: B

Rationale: The correct antidote for Warfarin is Vitamin K. Warfarin works by inhibiting vitamin K-dependent clotting factors. Administering Vitamin K helps reverse its effects by replenishing these factors. Choices A, C, and D are incorrect. Naloxone is used to reverse opioid overdose, Glucagon is used to treat severe low blood sugar, and Vitamin B is not the antidote for Warfarin.

2. 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.

3. 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.

4. When teaching a client with a new prescription for Simvastatin, which instruction should be included?

• A. Take this medication with food.
• B. Avoid drinking grapefruit juice.
• C. Take this medication in the morning.
• D. Increase your intake of potassium-rich foods.

Correct answer: B

Rationale: The correct instruction for a client with a new prescription for Simvastatin is to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Simvastatin, leading to increased blood levels of the drug and a higher risk of adverse effects such as muscle pain and liver damage. It is important to educate the client about this potential interaction to ensure the safe and effective use of the medication. Choices A, C, and D are incorrect because taking Simvastatin with food or in the morning and increasing potassium-rich foods intake are not specifically related to the safe use of Simvastatin. Avoiding grapefruit juice is crucial to prevent drug interactions.

5. A client has a new prescription for Efavirenz, an NNRTI. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime to prevent drowsiness.
• B. Take this medication with a glass of milk.
• C. Take this medication with a glass of juice.
• D. Take this medication at the same time every day.

Correct answer: A

Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.
