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.
Correct Answer: A
Rationale: Linezolid interacts with SSRIs like paroxetine, risking serotonin syndrome, requiring a washout period. Acetaminophen is safe, tyramine avoidance prevents hypertensive crises, and reporting fever/diarrhea monitors treatment response.
The nurse is caring for a client who just had a total thyroidectomy. Which finding does the nurse recognize as most important to report immediately?
- A. Elevated blood pressure
- B. Heart rate irregularity
- C. Low oxygen saturation
- D. Noisy breathing
Correct Answer: D
Rationale: Noisy breathing post-thyroidectomy may indicate airway obstruction from hematoma or edema, a life-threatening emergency. Other findings are less immediately critical but still require monitoring.
The health care provider has just prescribed tetracycline for an adolescent with acne vulgaris. The client takes oral contraceptive pills. The nurse should reinforce teaching about which topics? Select all that apply.
- A. Not taking tetracycline with dairy products
- B. Taking tetracycline at bedtime
- C. Taking tetracycline with food
- D. Using additional contraceptive techniques
- E. Using sunblock
Correct Answer: A,D,E
Rationale: Tetracycline binds to calcium in dairy, reducing absorption. It can reduce oral contraceptive efficacy, requiring backup methods. Photosensitivity necessitates sunblock. Taking with food or at bedtime is acceptable but not critical teaching.
The nurse is caring for a client who had a total thyroidectomy. What should the nurse plan to observe the client for immediately after his return to the nursing care unit?
- A. Hoarseness
- B. Signs of hypercalcemia
- C. Loss of reflexes
- D. Mental confusion
Correct Answer: B
Rationale: Total thyroidectomy risks parathyroid gland damage, leading to hypocalcemia (not hypercalcemia). However, the question likely intends hypocalcemia signs (tetany, spasms), which are critical to monitor immediately post-surgery. Hoarseness, reflexes, or confusion are less urgent.
The nurse evaluating a 52-year-old diabetic male client's therapeutic response to rosuvastatin would notice changes in which laboratory values? Select all that apply.
- A. Alanine aminotransferase from 20 U/L (0.33 ukat/L) to 80 U/L (1.34 ukat/L)
- B. High-density lipoprotein cholesterol from 48 mg/dL (1.24 mmol/L) to 30 mg/dL (0.78 mmol/L)
- C. Low-density lipoprotein cholesterol from 176 mg/dL (4.61 mol/L) to 98 mg/dL (2.54 mmol/L)
- D. Total cholesterol from 250 mg/dL (6.47 mmol/L) to 180 mg/dL (4.66 mmol/L)
- E. Triglycerides from 180 mg/dL (2.03 mmol/L) to 149 mg/dL (1.68 mmol/L)
Correct Answer: C,D,E
Rationale: Rosuvastatin, a statin, is expected to lower LDL cholesterol, total cholesterol, and triglycerides, indicating therapeutic response. An increase in alanine aminotransferase suggests liver stress, which is a side effect to monitor, not a therapeutic goal. A decrease in HDL cholesterol is undesirable, as statins typically maintain or increase HDL.
