1. A child who weighs 10 kg will begin taking oral trimethoprim-sulfamethoxazole (TMP-SMX). The liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL. The nurse determines that the child’s dose should be 8 mg of TMP and 40 mg of SMX/kg/day divided into two doses. Which order for this child is correct?
- A. 5 mL PO BID
- B. 5 mL PO daily
- C. 10 mL PO BID
- D. 10 mL PO daily
Correct answer: A
Rationale: The correct answer is A: '5 mL PO BID.' To calculate the child’s daily dose requirement, you multiply the child's weight (10 kg) by the prescribed dosage per kg, which is 8 mg for TMP and 40 mg for SMX. This results in a total daily requirement of 80 mg of TMP and 400 mg of SMX. To divide this into two doses, each dose should contain half of the total daily requirement, which is 40 mg TMP and 200 mg SMX. Since the liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL, the correct dose per administration is 5 mL. Therefore, 5 mL PO BID is the correct order. Choice B, '5 mL PO daily,' is incorrect as the total daily dose needs to be divided into two doses. Choices C and D, '10 mL PO BID' and '10 mL PO daily,' respectively, are incorrect as they do not align with the calculated dosage requirements based on the child's weight and the prescribed dosage per kg.
2. A client is starting urinary bladder training. Which statement should the nurse include in this client’s teaching?
- A. Use the toilet when you first feel the urge, rather than at specific intervals.
- B. Try to consciously hold your urine until the scheduled toileting time.
- C. Initially try to use the toilet at least every half hour for the first 24 hours.
- D. The toileting interval can be increased once you have been continent for a week.
Correct answer: B
Rationale: In urinary bladder training, the client should be taught to try to consciously hold their urine until the scheduled toileting time. This helps in training the bladder to hold urine for longer periods. Option A is incorrect because the goal is to consciously hold urine, not void immediately. Option C is incorrect as toileting at least every half hour may not promote bladder training. Option D is incorrect as increasing the toileting interval should be based on the client's comfort and progress, not just after being continent for a week.
3. A 68-year-old client on day 2 after hip surgery has no cardiac history but reports having chest heaviness. The first nursing action should be to:
- A. Inquire about the onset, duration, severity, and precipitating factors of the heaviness.
- B. Administer oxygen via nasal cannula.
- C. Offer pain medication for the chest heaviness.
- D. Inform the physician of the chest heaviness.
Correct answer: A
Rationale: The correct first nursing action when a client reports chest heaviness post-hip surgery is to gather more information through assessment. Inquiring about the onset, duration, severity, and precipitating factors of the heaviness is crucial to determine the cause. This approach helps the nurse to gather essential data to make an informed decision regarding the client's care. Administering oxygen (Choice B) may be indicated based on assessment findings, but it is crucial to assess first. Offering pain medication (Choice C) without further assessment is premature and may mask symptoms. Informing the physician (Choice D) should be done after a thorough assessment to provide comprehensive information for appropriate medical decision-making.
4. A client with chronic kidney disease starts on hemodialysis. During the first dialysis treatment, the client's blood pressure drops from 150/90 to 80/30. Which action should the nurse take first?
- A. Stop the dialysis treatment
- B. Administer 5% albumin IV
- C. Monitor blood pressure every 45 minutes
- D. Lower the head of the chair and elevate feet
Correct answer: D
Rationale: The initial action the nurse should take when a client's blood pressure drops significantly during hemodialysis is to lower the head of the chair and elevate the feet. This position adjustment helps improve blood flow to the brain and vital organs, assisting in stabilizing blood pressure. Stopping the dialysis treatment immediately may not be necessary if the blood pressure can be managed effectively by position changes. Administering 5% albumin IV is not the first-line intervention for hypotension during dialysis. Monitoring blood pressure every 45 minutes is important but not the immediate action needed to address the significant drop in blood pressure observed during the dialysis session.
5. The nurse is providing teaching to a patient who will begin taking a cephalosporin to treat an infection. Which statement by the patient indicates a need for further teaching?
- A. I may stop taking the medication if my symptoms clear up.
- B. I should eat yogurt while taking this medication.
- C. I should stop taking the drug and call my provider if I develop a rash.
- D. I will not consume alcohol while taking this medication.
Correct answer: A
Rationale: Patients should take all of an antibiotic regimen even after symptoms clear to ensure complete treatment of the infection.
