1. The nurse is changing the colostomy bag for a client who is complaining of leakage of diarrheal stool under the disposable ostomy bag. What action should the nurse implement to prevent leakage?

A. Place a 4x4 wick in the stoma opening
B. Apply a layer of zinc oxide ointment to the perimeter of the stoma
C. Cut the bag opening to the measurement of the stoma size
D. Administer a PRN antidiarrheal agent

Correct answer: C

Rationale: To prevent leakage of stool under the disposable ostomy bag, the nurse should cut the bag opening to the measurement of the stoma size. This action ensures a proper fit, which is crucial in preventing leaks that can lead to skin irritation and compromise stoma care. Placing a 4x4 wick in the stoma opening or applying zinc oxide ointment may not address the issue of leakage effectively. Administering a PRN antidiarrheal agent is not directly related to preventing leakage caused by an ill-fitting ostomy bag.

2. The nurse is caring for a client who has just undergone a total hip replacement. Which intervention is most important to prevent postoperative complications?

A. Encourage early ambulation
B. Apply ice to the surgical site
C. Monitor the surgical site for signs of infection
D. Administer pain medication as prescribed

Correct answer: A

Rationale: Encouraging early ambulation is crucial following a total hip replacement surgery as it helps prevent complications such as deep vein thrombosis (DVT) by promoting circulation. Early ambulation also aids in preventing pneumonia, muscle atrophy, and pressure ulcers. Applying ice to the surgical site may help with pain and swelling, but it is not as critical in preventing complications as early ambulation. While monitoring the surgical site for signs of infection is important, it is not as crucial in preventing postoperative complications compared to early ambulation. Administering pain medication as prescribed is essential for comfort and pain management but does not directly prevent postoperative complications like early ambulation does.

3. A client with hypothyroidism is being treated with levothyroxine (Synthroid). What is the most important information for the nurse to provide to the client?

A. Take the medication on an empty stomach
B. Monitor for signs of hyperthyroidism
C. Expect to see results within a week
D. Avoid exposure to sunlight

Correct answer: B

Rationale: The most important information for the nurse to provide to a client with hypothyroidism being treated with levothyroxine is to monitor for signs of hyperthyroidism. Too much levothyroxine can lead to symptoms of hyperthyroidism, indicating an overdose. Choice A is incorrect as levothyroxine is usually taken on an empty stomach to ensure optimal absorption. Choice C is inaccurate as it may take weeks to months to see the full effects of levothyroxine therapy due to the need for dosage adjustments. Choice D is unrelated to levothyroxine therapy and is not a crucial concern for this specific medication.

4. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

A. 400 mg/mL
B. 500 mg/mL
C. 450 mg/mL
D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

5. A 9-year-old is receiving vancomycin 400 mg IV every 6 hours for a methicillin-resistant (Beta-lactam-resistant) Staphylococci aureus (MRSA) infection. The medication is diluted in a 100 mL bag of saline with instructions to infuse over one and a half hours. How many mL/hour should the nurse program the infusion pump?

A. 50
B. 67
C. 57
D. 70

Correct answer: B

Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL ÷ 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.
