1. Which of the following is the best indicator of long-term glycemic control in a patient with diabetes?

• A. Fasting blood glucose levels.
• B. Postprandial blood glucose levels.
• C. Hemoglobin A1c.
• D. Random blood glucose levels.

Correct answer: C

Rationale: The correct answer is C, Hemoglobin A1c. Hemoglobin A1c measures the average blood glucose level over the past 2-3 months, providing a reliable indicator of long-term glycemic control. Fasting blood glucose levels (choice A) only offer a snapshot of the current glucose level and can fluctuate throughout the day. Postprandial blood glucose levels (choice B) reflect glucose levels after meals but do not give a comprehensive view of long-term control. Random blood glucose levels (choice D) are taken at any time and lack the consistency needed to assess long-term glycemic control effectively. Therefore, Hemoglobin A1c is the superior choice for monitoring and managing diabetes over an extended period.

2. A client has just returned to the nursing unit after computerized tomography (CT) with contrast medium. Which of the following actions should the nurse plan to take as part of routine after-care for this client?

• A. Administering a laxative
• B. Encouraging fluid intake
• C. Maintaining the client on strict bed rest
• D. Holding all medications for at least 2 hours

Correct answer: B

Rationale: After CT scanning with contrast medium, the client does not require special restrictions or interventions. Encouraging fluid intake is important to help flush out the contrast dye and prevent dehydration. Administering a laxative (Choice A) is unnecessary and not indicated after CT with contrast. Maintaining the client on strict bed rest (Choice C) is not necessary unless specified by the healthcare provider. Holding all medications for at least 2 hours (Choice D) is not a standard practice after CT with contrast.

3. A nursing assistant is measuring the blood pressure (BP) of a hypertensive client while a nurse observes. Which action on the part of the assistant would interfere with accurate measurement and prompt the nurse to intervene? Select all that apply.

• A. Measuring the BP after the client has sat quietly for 5 minutes
• B. Having the client sit with the arm bared and supported at heart level
• C. Using a cuff with a rubber bladder that encircles less than 80% of the limb
• D. Measuring the BP after the client reports that he just drank a cup of coffee

Correct answer: C

Rationale: To ensure accurate blood pressure (BP) measurement, the cuff used should have a rubber bladder that encircles at least 80% of the limb being measured. This ensures proper compression and accurate readings. Choices A and B are correct practices as it is recommended to measure BP after the client has sat quietly for 5 minutes and to have the client sit with the arm bared and supported at heart level. Choice D is also a correct reason for intervention as the client should not have consumed caffeine or smoked tobacco within 30 minutes before BP measurement, as it can affect the accuracy of the reading.

4. The patient weighs 75 kg and is receiving IV fluids at a rate of 50 mL/hour, having consumed 100 mL orally in the past 24 hours. What action will the nurse take?

• A. Contact the provider to ask about increasing the IV rate to 90 mL/hour.
• B. Discuss with the provider the need to increase the IV rate to 150 mL/hour.
• C. Encourage the patient to drink more water so the IV can be discontinued.
• D. Instruct the patient to drink 250 mL of water every 8 hours.

Correct answer: A

Rationale: The recommended daily fluid intake for adults is 30 to 40 mL/kg/day. For a patient weighing 75 kg, the minimum intake should be 2250 mL/day. The patient is currently receiving 1200 mL IV and 100 mL orally, totaling 1300 mL. Increasing the IV rate to 90 mL/hour would provide a total of 2160 mL, which could meet the patient's needs if oral intake continues. Option B suggests increasing the IV rate to 150 mL/hour, resulting in an excessive fluid intake of 3600 mL/day, surpassing the recommended amount. Option C, encouraging increased fluid intake, is not recommended as the patient is already struggling with fluid intake. Option D, instructing the patient to drink 250 mL of water every 8 hours, would still fall short of the required fluid intake of 2250 mL/day.

5. The nurse is obtaining a health history from a new client who has a history of kidney stones. Which statement by the client indicates an increased risk for renal calculi?

• A. Eats a vegetarian diet with cheese 2 to 3 times a day
• B. Experiences additional stress since adopting a child
• C. Jogs more frequently than usual daily routine
• D. Drinks several bottles of carbonated water daily

Correct answer: D

Rationale: The correct answer is D. Drinking several bottles of carbonated water daily may contribute to renal calculi formation due to the high mineral content. Carbonated drinks can increase the risk of kidney stones due to their high levels of phosphoric acid and caffeine, which can lead to the formation of crystals in the urine. Choices A, B, and C are less likely to directly contribute to an increased risk of renal calculi compared to the excessive consumption of carbonated water.
