Correct Answer: D

Rationale: The correct answer is D: 'Trim toenails straight across.' In clients with diabetes, trimming toenails straight across is important to prevent ingrown toenails, reducing the risk of infections. Soaking feet in warm water daily (choice A) can lead to dry skin and potentially cause skin breakdown in diabetic clients. While wearing cotton socks (choice B) is beneficial for good foot hygiene, it is not as crucial as trimming toenails correctly. Applying lotion to feet after bathing (choice C) is helpful for moisturizing the skin, but the emphasis should be on nail care to prevent complications like ingrown toenails.

Correct Answer: C

Rationale: The correct answer is C. A serum creatinine level of 2.8 mg/dL indicates impaired kidney function and should be reported to the healthcare provider. Elevated serum creatinine levels are indicative of decreased kidney function and potential progression of chronic kidney disease. Choices A, B, and D are within normal ranges and do not signify immediate concerns related to kidney disease. Urine output of 80 mL/hr is appropriate, a blood pressure of 140/90 mm Hg is considered prehypertensive but not acutely concerning, and a heart rate of 72/min falls within the normal range.

Correct Answer: C

Rationale: The correct answer is C. A heart rate of 88/min is a normal finding; therefore, it does not require immediate reporting to the provider. The respiratory rate of 20/min, blood pressure of 118/76 mm Hg, and oxygen saturation of 94% are also within normal ranges and do not indicate any immediate concerns. However, a serum potassium level of 3.0 mEq/L indicates hypokalemia, which can be a serious issue and should be reported to the provider for further evaluation and management.

Correct Answer: A

Rationale: Monitoring oxygen saturation is crucial in assessing a patient with respiratory distress because it helps determine if the patient is receiving adequate oxygen. Oxygen saturation levels provide immediate feedback on the efficiency of oxygen delivery to the tissues. Checking for abnormal breath sounds (Choice B) is relevant in respiratory assessments, but it is secondary to assessing oxygen saturation. Pitting edema (Choice C) and performing a neurological exam (Choice D) are not directly related to assessing respiratory distress and are not the primary focus when managing a patient with breathing difficulties.

Correct Answer: C

Rationale: Checking the client's blood glucose level every 4 hours is essential when managing a client on TPN to monitor for hyperglycemia, a common complication. Monitoring urine output (Choice A) is important but not a priority in this scenario. Administering a bolus of 0.9% sodium chloride (Choice B) is not indicated as it is unrelated to managing TPN. Flushing the TPN line with sterile water (Choice D) is necessary, but it should be done with 0.9% sodium chloride, not water.
