A client with a new diagnosis of type 1 diabetes mellitus is being taught by a nurse about insulin administration. Which of the following instructions should the nurse include?

Correct Answer: B

Rationale: The correct answer is to rotate injection sites within the same region to prevent tissue damage. By rotating sites, the client can prevent lipodystrophy, which is a condition characterized by the loss or change in body fat at the site of repeated injections. This practice also helps to ensure proper insulin absorption. Storing unopened vials of insulin in the refrigerator (Choice A) is correct, not in the freezer, as freezing can damage the insulin. Administering insulin at a 90-degree angle (Choice C) is more appropriate for subcutaneous injections, while a 45-degree angle is used for intramuscular injections. Massaging the injection site after administering insulin (Choice D) is not recommended as it can affect insulin absorption rates.

Correct Answer: C

Rationale: The correct action for the nurse to take when caring for a client with a chest tube connected to a water-seal drainage system is to add sterile water to the water-seal chamber. This is necessary to maintain the correct water level for proper chest tube function. Clamping the chest tube during ambulation (Choice A) is incorrect as it can lead to complications by obstructing drainage. Keeping the collection chamber below the level of the chest (Choice B) is incorrect because it should be kept below the chest to facilitate drainage. Emptying the collection chamber every 12 hours (Choice D) is incorrect as it should be emptied whenever it reaches the fill line or as per facility policy, not on a fixed time schedule.

Correct Answer: D

Rationale: Measuring the client's intake and output every 2 hours is essential when caring for a client receiving a continuous IV infusion of milrinone. Milrinone is a medication that affects fluid balance, and monitoring intake and output helps assess the client's response to the medication. Continuous monitoring of blood pressure may not be necessary unless there is a specific indication. While weighing the client daily is important for overall assessment, measuring intake and output more frequently provides more real-time data for fluid balance evaluation. Monitoring the infusion site is crucial for detecting infiltration but is not directly related to managing fluid balance in this situation.

Correct Answer: B

Rationale: The correct answer is B. An elevated temperature of 38.2°C (100.8°F) indicates a potential infection and should be reported to the provider. Elevated temperature postoperatively is often a sign of infection or inflammation, which can delay healing and increase the risk of complications. Choices A, C, and D are within normal ranges for a postoperative client and do not indicate an immediate need for reporting to the provider. Serous drainage at the incision site is expected in the initial postoperative period as part of the normal healing process, a heart rate of 92/min can be a normal response to surgery due to stress or pain, and a blood pressure of 130/80 mm Hg is also within normal limits for most clients.

Correct Answer: C

Rationale: The correct statement is C: 'Exercise for at least 30 minutes most days of the week.' Regular exercise is essential in managing blood pressure as it helps improve cardiovascular health. Choice A is incorrect as increasing red meat intake can be detrimental due to its high saturated fat content, which can negatively impact blood pressure. Choice B is not directly related to managing blood pressure unless the medication interacts negatively with alcohol. Choice D, limiting fluid intake to 3 liters per day, is not a general recommendation for managing blood pressure unless specifically advised by a healthcare provider.
