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.

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.

A client with a severe headache is being assessed by a nurse. What should the nurse do first?

• A. Administer pain relief medication
• B. Check the client's blood pressure
• C. Assess for associated symptoms such as nausea or photophobia
• D. Offer a quiet environment

Correct Answer: B
Rationale: When a client presents with a severe headache, the initial action should be to check their blood pressure. This step is crucial as it can help determine if the headache is related to hypertension or other cardiovascular issues. Administering pain relief medication should only be done after assessing the client's vital signs and confirming the cause of the headache. While assessing for associated symptoms like nausea or photophobia is important for a comprehensive evaluation, it should follow checking the blood pressure to address immediate concerns. Offering a quiet environment is indeed beneficial for the client's comfort, but it is not the priority when dealing with a severe headache.

The nurse observes that a male client's urinary catheter (Foley) drainage tubing is secured with tape to his abdomen and then attached to the bed frame. What action should the nurse implement?

• A. Raise the bed to ensure the drainage bag remains off the floor
• B. Attach the drainage bag to the side rail instead of the bed frame
• C. Observe the appearance of the urine in the drainage tubing
• D. Secure the tubing to the client's gown instead of his abdomen

Correct Answer: D
Rationale: The correct action for the nurse to implement is to secure the tubing to the client's gown instead of his abdomen. Securing the tubing to the client's abdomen can cause discomfort, trauma to the urethra, and increase the risk of infection. Attaching the drainage bag to the bed frame can lead to tension on the catheter, increasing the risk of dislodgement or trauma. Raising the bed does not address the issue of incorrect tubing securing. Observing the appearance of urine is important but secondary to ensuring proper tubing attachment.

What intervention should the nurse implement for a client experiencing an anxiety attack?

• A. Teach deep breathing exercises
• B. Provide a quiet environment
• C. Administer anxiolytic medication as prescribed
• D. Engage the client in conversation

Correct Answer: C
Rationale: Administering prescribed anxiolytic medication is the most appropriate intervention for a client experiencing an anxiety attack. Anxiolytic medications can provide rapid relief from severe anxiety symptoms. Teaching deep breathing exercises (choice A) can be helpful for managing mild anxiety but may not be sufficient during an acute anxiety attack. Providing a quiet environment (choice B) is beneficial to reduce stimuli, but it may not address the immediate distress of an ongoing anxiety attack. Engaging the client in conversation (choice D) is generally not recommended during an anxiety attack as it can potentially exacerbate the symptoms by increasing stimulation.
