Correct Answer: B

Rationale: The correct answer is B, Glycosylated hemoglobin (HbA1c). HbA1c provides a measure of long-term blood glucose control over the past 2-3 months. This test reflects the average blood glucose levels during this period, making it a valuable tool in managing diabetes. Choices A, C, and D are not indicators of long-term blood glucose control. Fasting blood glucose measures the current glucose level after a period of not eating, random blood glucose provides a snapshot of the current glucose level, and postprandial blood glucose measures the glucose level after a meal.

Correct Answer: B

Rationale: The correct answer is B: Monitor serum creatinine. Serum creatinine is a key indicator of renal function as it reflects the glomerular filtration rate. An increase in serum creatinine levels indicates impaired kidney function. Checking blood glucose levels (choice A) is not specific to assessing renal function but is used to diagnose diabetes. Monitoring BUN (choice C) is important but not as specific as serum creatinine in assessing renal function. Checking electrolyte levels (choice D) is essential in assessing kidney function but is not as specific as monitoring serum creatinine.

Correct Answer: B

Rationale: The correct instruction is to rinse the mouth after each use of a corticosteroid inhaler to prevent oral candidiasis (thrush). Choice A is incorrect because corticosteroid inhalers are usually used on a regular schedule to control asthma symptoms, not just for acute symptoms. Choice C is incorrect as corticosteroid inhalers are typically used for long-term management, not just during asthma attacks. Choice D is incorrect as administering a bronchodilator after using a corticosteroid is not a standard practice and is not necessary for the effectiveness of the corticosteroid inhaler.

Correct Answer: B

Rationale: The correct answer is to place the client in a high-Fowler's position. This position helps improve breathing by expanding the lungs and aiding in better oxygenation. Encouraging the client to take deep breaths may not be effective in managing dyspnea in COPD as it can lead to fatigue. Administering a bronchodilator may be necessary but placing the client in a high-Fowler's position should be the priority. Administering oxygen at 6 L/min via face mask may also be needed, but positioning is the initial intervention to optimize respiratory function.

Correct Answer: B

Rationale: Muscle weakness is a common finding in clients with hypokalemia, as potassium is essential for proper muscle function. Diarrhea (choice A) is more commonly associated with hyperkalemia rather than hypokalemia. Hypertension (choice C) is not typically a direct result of low potassium levels. Bradycardia (choice D) is more commonly associated with hyperkalemia, not hypokalemia.
