Question 1 of 5
A nurse is preparing to administer somatropin 0.24 mg/kg/week subcutaneously to be divided into six daily doses to a school-age child who weighs 66 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: 66 lb = 30 kg; 0.24 mg/kg/week = 7.2 mg/week; 7.2 mg / 6 doses = 1.2 mg/dose, rounded to 1.2 mg.
Question 2 of 5
A nurse is reinforcing teaching with a client who has chronic stable angina and a new prescription for sublingual nitroglycerin. Which of the following instructions should the nurse include in the teaching?
Correct Answer: B
Rationale: Taking sublingual nitroglycerin before strenuous activity prevents angina. It's taken without water, up to three tablets (not four) in 15 minutes, and dissolved under the tongue (not chewed).
Question 3 of 5
A nurse is assisting in the care of a client who is receiving morphine via a continuous epidural infusion. Which of the following findings should the nurse report to the provider immediately?
Correct Answer: A
Rationale: A respiratory rate of 10/min indicates respiratory depression, a serious and potentially life-threatening side effect of morphine requiring immediate reporting. Facial flushing and constipation are common but less urgent, and hypotension, while concerning, is not as immediately critical as respiratory depression.
Question 4 of 5
A nurse is reinforcing teaching with a client who has a new prescription for prednisone to treat rheumatoid arthritis. Which of the following statements should indicate to the nurse that the client understands the teaching?
Correct Answer: B
Rationale: Reporting a sore throat shows understanding of prednisone's immunosuppressive effect, increasing infection risk. It's taken with food, sodium increase worsens fluid retention, and weight gain is expected.
Question 5 of 5
A nurse is preparing to mix NPH insulin and regular insulin for administration. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Injecting air into each vial equalizes pressure for accurate withdrawal; regular insulin is drawn first, then NPH. Tuberculin syringes aren't standard, NPH isn't withdrawn first, and shaking regular insulin risks bubbles.
