A healthcare professional is reviewing the laboratory results of a client who is receiving total parenteral nutrition (TPN). Which of the following findings should the professional report to the provider?

Correct Answer: C

Rationale: A serum potassium level of 3.2 mEq/L indicates hypokalemia, a complication that should be reported in clients receiving TPN. Hypokalemia can lead to serious cardiac and neuromuscular complications. The other options are within normal ranges and do not indicate immediate concerns for a client receiving TPN. A blood glucose level of 130 mg/dL, serum sodium level of 140 mEq/L, and platelet count of 250,000/mm³ are all considered normal values and do not require immediate intervention.

Correct Answer: D

Rationale: The correct answer is D. Warfarin's effectiveness is reduced by high intake of vitamin K-rich foods, so increasing their intake would contradict the treatment plan. Choices A, B, and C are all appropriate statements for a client on warfarin therapy. Avoiding vitamin K-rich foods helps maintain the medication's effectiveness, avoiding aspirin reduces the risk of bleeding, and monitoring blood pressure is essential for overall health monitoring.

Correct Answer: D

Rationale: The correct method to teach a patient about self-administration of insulin is to use a 90-degree angle for injection. This angle ensures proper subcutaneous administration of insulin, which is essential for effective absorption. Injecting into the upper arm (Choice A) is not recommended for insulin administration. While rotating injection sites (Choice B) is important to prevent lipodystrophy, the angle of injection is crucial for proper insulin delivery. Using a 45-degree angle (Choice C) is more suitable for intramuscular injections, not for subcutaneous insulin injections.

Correct Answer: C

Rationale: To promote optimal skin integrity in a client with a colostomy, using a barrier cream to protect the skin from the irritating effects of the colostomy pouch contents is essential. Cleansing the peristomal skin with alcohol (Choice A) can be too harsh and drying for the skin. Changing the colostomy pouch every 3 days (Choice B) is important for hygiene but using a barrier cream is more directly related to skin protection. Cleaning the stoma with hydrogen peroxide (Choice D) is not recommended as it can be too abrasive for the sensitive stoma area.

Correct Answer: C

Rationale: The correct answer is C: 'Trim your toenails straight across.' Trimming toenails straight across helps prevent ingrown toenails, which is important for clients with diabetes to prevent infections. Choice A is incorrect because soaking feet in warm water can lead to skin breakdown and infections. Choice B is incorrect as cotton socks can retain moisture, increasing the risk of fungal infections. Choice D is also incorrect as applying lotion between the toes can create a moist environment, increasing the risk of infections.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin 12 g/dL. In a client with heart failure, a decrease in hemoglobin levels can indicate anemia, which can exacerbate heart failure symptoms. Reporting this finding to the provider is crucial for appropriate management. Choice A, Potassium 4.0 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not typically require immediate reporting. Choice C, BUN 18 mg/dL, and Choice D, Sodium 137 mEq/L, are also within normal ranges and not directly related to heart failure management. Therefore, the hemoglobin level is the most critical finding to report in this scenario.

Correct Answer: C

Rationale: To prevent aspiration in clients receiving continuous enteral feedings, the nurse should elevate the head of the bed to 45 degrees. This position helps reduce the risk of regurgitation and aspiration. Flushing the tube with water every 4 hours (Choice A) is important for maintaining tube patency but does not directly prevent aspiration. Positioning the client on the left side during feedings (Choice B) is not specifically related to preventing aspiration in this context. Checking gastric residual every 2 hours (Choice D) is important to assess feeding tolerance but does not directly prevent aspiration.

Correct Answer: A

Rationale: Monitoring the dressing site daily is crucial for detecting early signs of infection in patients with central lines. Checking for redness and swelling (choice B) is important but may indicate a more advanced stage of infection. Monitoring for fever (choice C) can also be a sign of infection, but it is a later manifestation. Flushing the central line (choice D) is necessary for maintaining patency but does not directly monitor for infection.

Correct Answer: C

Rationale: The correct answer is C: 'Use a blood pressure cuff that fits snugly around the arm.' Using a properly fitting cuff is essential for accurate blood pressure measurements. Choice A is incorrect because the timing of medication administration should be individualized and not specified in the question. Choice B is incorrect as checking blood pressure once a week may not provide sufficient monitoring for a client with hypertension. Choice D is incorrect because stopping medication abruptly once blood pressure is normal can lead to rebound hypertension and complications.
