Question 1 of 5
A nurse is caring for a client who is prescribed 15 units of NPH insulin to be administered at 0700. At which of the following times of day is most appropriate for the nurse to plan to offer a snack?
Correct Answer: A
Rationale: NPH insulin is an intermediate-acting insulin that peaks 6-8 hours after administration. Offering a snack at 1500 helps prevent hypoglycemia during the peak action of the insulin.
Question 2 of 5
A nurse is preparing to administer prednisone 40 mg PO to an adolescent client. Available is prednisone oral solution 5 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 40 mL
Rationale: Volume (mL) = Desired dose (40 mg) / Concentration (5 mg/5 mL) = 40 mL.
Question 3 of 5
A nurse is checking the laboratory results of a client who is at risk for diabetes mellitus. Which of the following laboratory results indicates to the nurse that the client is at risk for diabetes mellitus?
Correct Answer: B
Rationale: A fasting blood glucose level of 155 mg/dL is above the normal threshold (greater than 126 mg/dL indicates diabetes).
Question 4 of 5
A nurse is caring for a client who has type 1 diabetes mellitus and observes mild hand tremors. Which of the following snacks should the nurse offer the client after obtaining a glucometer reading of 60 mg/dL?
Correct Answer: A
Rationale: Regular soda provides a fast-acting source of glucose, which is essential for quickly raising blood sugar levels in a hypoglycemic event.
Question 5 of 5
A nurse is preparing to administer a dexamethasone 1.5 mg/kg/day PO to divide equally every 6 hr to a preschool-age child who weighs 22 lb. Available is dexamethasone oral solution 1 mg/mL. How many mL 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: 3.8 mL
Rationale: Convert 22 lb to 10 kg.
Total daily dose = 1.5 mg/kg/day * 10 kg = 15 mg/day. Dose per administration = 15 mg / 4 doses = 3.75 mg. Volume = 3.75 mg / 1 mg/mL = 3.75 mL, rounded to 3.8 mL.
