1. A client with diabetes is taking insulin lispro (Humalog) injections. The nurse should advise the client to eat:

A. Within 10 to 15 minutes after the injection.
B. 1 hour after the injection.
C. At any time, because timing of meals with lispro injections is unnecessary.
D. 2 hours before the injection.

Correct answer: A

Rationale: The correct answer is to eat within 10 to 15 minutes after the injection. Insulin lispro, also known as Humalog, is a rapid-acting insulin that starts working very quickly. Eating shortly after the injection helps match the food intake with the insulin action, reducing the risk of hypoglycemia. Choice B is incorrect because waiting 1 hour after the injection may lead to a mismatch between insulin activity and food intake. Choice C is incorrect as timing meals with lispro injections is essential to optimize glycemic control. Choice D is incorrect as eating 2 hours before the injection is not in alignment with the rapid action of insulin lispro and may lead to fluctuations in blood sugar levels.

2. Which of the following is a sign of hypocalcemia?

A. Hyperactive reflexes.
B. Depressed reflexes.
C. Muscle cramps.
D. Seizures.

Correct answer: A

Rationale: Hyperactive reflexes are a classic sign of hypocalcemia. Hypocalcemia leads to increased neuromuscular excitability, resulting in hyperactive reflexes. Depressed reflexes (Choice B) are not typically associated with hypocalcemia. Muscle cramps (Choice C) can be seen in hypocalcemia due to muscle irritability but are not a specific sign. Seizures (Choice D) can occur in severe cases of hypocalcemia but are not as common as hyperactive reflexes.

3. Which of the following indicates a potential complication of diabetes mellitus?

A. Inflamed and painful joints.
B. Blood pressure of 160/100 mm Hg.
C. Stooped posture.
D. Hemoglobin of 9 g/dL (90 g/L).

Correct answer: B

Rationale: A blood pressure of 160/100 mm Hg indicates hypertension, which is a common complication of diabetes mellitus due to atherosclerotic changes. Hypertension is a significant risk factor for cardiovascular diseases, which are prevalent in individuals with diabetes. Inflamed and painful joints (Choice A) are not directly related to diabetes complications but may be seen in conditions like arthritis. Stooped posture (Choice C) is more indicative of musculoskeletal issues like osteoporosis, not necessarily a typical complication of diabetes. Hemoglobin level of 9 g/dL (90 g/L) (Choice D) could signify anemia, which can occur in diabetes but is not a primary complication often associated with the disease.

4. A child who weighs 10 kg will begin taking oral trimethoprim-sulfamethoxazole (TMP-SMX). The liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL. The nurse determines that the child’s dose should be 8 mg of TMP and 40 mg of SMX/kg/day divided into two doses. Which order for this child is correct?

A. 5 mL PO BID
B. 5 mL PO daily
C. 10 mL PO BID
D. 10 mL PO daily

Correct answer: A

Rationale: The correct answer is A: '5 mL PO BID.' To calculate the child’s daily dose requirement, you multiply the child's weight (10 kg) by the prescribed dosage per kg, which is 8 mg for TMP and 40 mg for SMX. This results in a total daily requirement of 80 mg of TMP and 400 mg of SMX. To divide this into two doses, each dose should contain half of the total daily requirement, which is 40 mg TMP and 200 mg SMX. Since the liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL, the correct dose per administration is 5 mL. Therefore, 5 mL PO BID is the correct order. Choice B, '5 mL PO daily,' is incorrect as the total daily dose needs to be divided into two doses. Choices C and D, '10 mL PO BID' and '10 mL PO daily,' respectively, are incorrect as they do not align with the calculated dosage requirements based on the child's weight and the prescribed dosage per kg.

5. A healthcare professional has a prescription to collect a 24-hour urine specimen from a client. Which of the following measures should the healthcare professional take during this procedure?

A. Keeping the specimen chilled
B. Saving the first urine specimen collected at the start time
C. Discarding the last voided specimen at the end of the collection time
D. Asking the client to void, discarding the specimen, and noting the start time

Correct answer: D

Rationale: The correct answer is asking the client to void, discarding the specimen, and noting the start time. During a 24-hour urine collection, the first voided urine is discarded to ensure the test starts with an empty bladder. The specimen should be kept chilled, not at room temperature, to prevent bacterial growth. The last voided specimen is not discarded because it contributes to the total volume collected, so choice C is incorrect. Discarding the specimen and noting the start time is essential for accurate results in a timed quantitative determination like a 24-hour urine collection.
