Question 1 of 5
A nurse is reviewing the laboratory report of a client who has hypoparathyroidism. The nurse should expect which of the following values?
Correct Answer: D
Rationale: Hypoparathyroidism results in hypocalcemia and hyperphosphatemia due to insufficient parathyroid hormone (PTH) secretion. A phosphate level of 5.7 mg/dL is elevated, which is consistent with this condition.
Question 2 of 5
A nurse is reinforcing teaching about exercise with a client who has type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: C
Rationale: Injecting insulin into the thigh before running can increase absorption rates, leading to hypoglycemia. Rotating injection sites and avoiding muscle groups that will be heavily exercised is recommended.
Question 3 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.
Question 4 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 5 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.
