Question 1 of 5
A nurse is caring for a child who has recurrent otitis media. The child weighs 14.9 kg (33 lb). A prescription is written for amoxicillin 40 mg/kg PO to be given in two divided doses per day. The pharmacy provides the nurse with amoxicillin 250 mg/5 mL. How many mL of the medication should the nurse plan to administer for each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 6
Rationale: 14.9 kg × 40 mg/kg = 596 mg/day; 596 mg ÷ 2 = 298 mg/dose; 298 mg ÷ (250 mg/5 mL) = 5.96 mL ≈ 6 mL per dose.
Question 2 of 5
A nurse is reviewing the medication administration record of a client who has a wound infection. The client has prescriptions for cefotetan and an NSAID. The nurse should monitor for which of the following medication interactions?
Correct Answer: A
Rationale: Bleeding risks increase as cefotetan affects clotting and NSAIDs inhibit platelets. Dysrhythmias, dizziness, and jaundice aren't primary interactions.
Question 3 of 5
A nurse is collecting data from a client following the administration of a new medication. Which of the following findings should the nurse identify as a manifestation of an allergic reaction?
Correct Answer: B
Rationale: Urticaria is a classic allergic sign due to histamine release. Jaundice suggests liver issues, bradycardia and hypertension aren't typical allergy manifestations.
Question 4 of 5
A nurse is monitoring a client's response to receiving glipizide instead of guaifenesin. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: Offer the client a carbohydrate snack counters glipizide's hypoglycemia risk. Bed position, urinary retention, and reflexes aren't relevant.
Question 5 of 5
A nurse is caring for a client who has Graves' disease and is to start therapy with propylthiouracil. The nurse should expect which of the following outcomes?
Correct Answer: C
Rationale: Decreased heart rate is expected as propylthiouracil reduces thyroid hormone, slowing metabolism. Hct and blood pressure don't increase, and WBC decrease is a side effect, not an outcome.
