The nurse is caring for a client who has a prescription for cefuroxime 30 mg/kg/day PO in 2 divided doses. The client weighs 35 lb (15.9 kg). The nurse has cefuroxime 250 mg/5 mL available. How many mL should the nurse administer to the client with each dose? Record your answer using 1 decimal place.
Correct Answer: 2.9
Rationale: Total daily dose: 30 mg/kg × 15.9 kg = 477 mg/day. Divided into 2 doses: 477 ÷ 2 = 238.5 mg/dose. Using 250 mg/5 mL: (238.5 mg ÷ 250 mg) × 5 mL = 4.77 mL. Per 2 doses: 4.77 ÷ 2 = 2.385, rounded to 2.9 mL per dose.

The nurse is reviewing discharge instructions with a client going home on linezolid therapy for a vancomycin-resistant enterococcus infection. Which client statement requires further teaching?
- A. I can restart my paroxetine once I get back home.
- B. I can take acetaminophen for headaches.
- C. I will avoid foods and drinks that contain tyramine.
- D. I will report any increased fever or diarrhea.

A 57 year-old male client has a hemoglobin of 10 mg/dl and a hematocrit of 32%. What would be the most appropriate follow-up by the home care nurse?

- C. Schedule a repeat Hemoglobin and Hematocrit in 1 month

Which of these findings indicate that a pump set to deliver a basal rate of 10 ml per hour plus PRN morphine drip for breakthrough pain is not working?
- A. The client complains of discomfort at the IV insertion site
- B. The client states 'I just can't get relief from my pain'
- C. The level of the drug is 100 ml at 8 AM and is 80 ml at noon
- D. The infusion is running at a rate higher than expected
Correct Answer: C
Rationale: The minimal dose is 10 ml per hour, which would mean 40 mls are given in a 4 hour period. Only 60 mls should be left at noon. The pump is not functioning when more than expected medicine is left in the container.

- D. 72-year-old who is incontinent with acute altered mental status and is yelling at staff
Correct Answer: B
Rationale: Neck swelling and pain post-thyroidectomy suggest possible hematoma or airway compromise, a life-threatening emergency requiring immediate assessment. Other conditions, while serious, are less immediately critical.
