Nursing Elites

1. 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.

2. The nurse is assessing a client with hyperkalemia. Which finding is consistent with this electrolyte imbalance?

• A. Muscle weakness
• B. Decreased deep tendon reflexes
• C. Constipation
• D. Hypotension

Correct answer: A

Rationale: Muscle weakness is a common finding in clients with hyperkalemia. Hyperkalemia can lead to muscle weakness due to the effect of high potassium levels on muscle function. Decreased deep tendon reflexes (Choice B) are not typically associated with hyperkalemia; instead, hyperreflexia or increased reflexes may be observed. Constipation (Choice C) is not a common symptom of hyperkalemia. Hypotension (Choice D) is also not a typical finding in hyperkalemia; instead, hypertension or normal blood pressure may be present.

3. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?

• A. Alkalosis
• B. Acidosis
• C. Normal serum pH
• D. Incompatible with life

Correct answer: C

Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.

4. The nurse is caring for a client with an intravenous infusion of normal saline. The client reports pain and swelling at the IV site. What is the nurse’s priority action?

• A. Slow the rate of infusion
• B. Apply a warm compress to the site
• C. Discontinue the IV infusion
• D. Elevate the affected arm

Correct answer: C

Rationale: The correct answer is to discontinue the IV infusion (Choice C). Pain and swelling at the IV site can indicate infiltration or phlebitis, which are serious complications that require immediate action. Slowing the rate of infusion (Choice A) may not address the underlying issue and can potentially worsen the condition. Applying a warm compress (Choice B) may provide temporary relief but does not address the need to discontinue the infusion. Elevating the affected arm (Choice D) is not the priority in this situation; discontinuing the infusion takes precedence to prevent further harm.

5. A postoperative client complains of sudden shortness of breath. What should the nurse do first?

• A. Administer oxygen
• B. Call the healthcare provider
• C. Prepare for chest x-ray
• D. Assess the client's lung sounds

Correct answer: D

Rationale: Assessing the client's lung sounds is the most appropriate initial action when a postoperative client complains of sudden shortness of breath. This step helps the nurse evaluate the respiratory status and detect abnormalities such as decreased breath sounds or crackles, which could indicate a serious condition like a pulmonary embolism. Administering oxygen (Choice A) may be necessary but should come after assessing the lung sounds to ensure the appropriate intervention. Calling the healthcare provider (Choice B) or preparing for a chest x-ray (Choice C) can be important subsequent actions based on the findings from the lung sound assessment, but they are not the first priority in this situation.
