Nursing Elites

1. A client is receiving vancomycin. Which of the following laboratory results should be monitored to evaluate the therapeutic effect of this medication?

• A. BUN
• B. Creatinine
• C. Hemoglobin
• D. White blood cell count

Correct answer: B

Rationale: Corrected Rationale: Creatinine levels should be monitored to evaluate vancomycin's effect on kidney function. Vancomycin can be nephrotoxic, so monitoring creatinine levels helps assess renal function and ensure that the medication is not causing harm to the kidneys. Monitoring BUN (choice A) is important for assessing kidney function but is not as specific as monitoring creatinine levels. Hemoglobin (choice C) and white blood cell count (choice D) are not directly related to evaluating the therapeutic effect of vancomycin.

2. When teaching a client with a prescription for Cephalexin, which of the following instructions should the nurse include?

• A. Take the medication with an antacid.
• B. Avoid dairy products while taking this medication.
• C. Expect your stools to turn black.
• D. Complete the full course of medication.

Correct answer: D

Rationale: The correct instruction for a client prescribed with Cephalexin is to complete the full course of medication. This is crucial to ensure the infection is completely treated and to reduce the risk of antibiotic resistance. Choices A, B, and C are incorrect. Taking Cephalexin with an antacid is generally not recommended as it may reduce its effectiveness. While dairy products can interfere with certain antibiotics, they do not have a direct interaction with Cephalexin. Stools turning black is not an expected side effect of Cephalexin.

3. A healthcare provider is caring for a group of clients who are not protected against Varicella. The healthcare provider should prepare to administer the Varicella vaccine at this time to which of the following clients?

• A. 24-year-old woman in the third trimester of pregnancy
• B. 12-year-old child who has a severe allergy to neomycin
• C. 2-month-old infant who has no health problems
• D. 32-year-old man who has essential hypertension

Correct answer: D

Rationale: The correct answer is the 32-year-old man who has essential hypertension. Individuals who did not receive two doses of the varicella vaccine earlier in life should be immunized. Essential hypertension is not a contraindication for this vaccine, making it safe to administer to this client. Choice A is incorrect because administering the Varicella vaccine is contraindicated during pregnancy due to the risk of transmission to the fetus. Choice B is incorrect because a severe allergy to neomycin is a contraindication to the Varicella vaccine, which contains a trace amount of neomycin. Choice C is incorrect because the Varicella vaccine is not recommended for infants under 12 months of age.

4. Which medication is a beta blocker?

• A. Atenolol (Tenormin)
• B. Verapamil (Calan)
• C. Captopril (Capoten)
• D. Clopidogrel (Plavix)

Correct answer: A

Rationale: Atenolol (Tenormin) is a beta blocker commonly used to treat conditions like hypertension and angina by blocking the action of adrenaline on the heart. Verapamil is a calcium channel blocker, Captopril is an ACE inhibitor, and Clopidogrel is an antiplatelet medication. Therefore, the correct answer is Atenolol (Tenormin) as it belongs to the beta blocker class of medications.

5. A healthcare provider 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 dextrose 5% in water (D5W) over 6 hours. Choice B, 100 mL/hr, is incorrect as it does not match the correct calculation. Choice C, 150 mL/hr, is incorrect as it is higher than the calculated flow rate. Choice D, 200 mL/hr, is incorrect as it is also higher than the calculated flow rate.
