Correct Answer: B

Rationale: Glycosylated hemoglobin (HbA1c) is the most accurate test for long-term management of blood glucose levels in individuals with diabetes mellitus. HbA1c reflects average blood glucose levels over the past 2-3 months, providing valuable information on the effectiveness of treatment and disease control. Postprandial blood glucose, glucose tolerance test, and fasting blood glucose are essential for monitoring blood glucose levels at specific times but do not offer the same insight into long-term disease management as HbA1c.

Correct Answer: A

Rationale: Polyuria is the excessive production of urine and is a common finding in clients with hyperglycemia due to increased glucose levels. High blood sugar levels lead to the body trying to eliminate the excess glucose through urine, resulting in increased urination. Hypoglycemia (choice B) is low blood sugar and is not typically associated with hyperglycemia. Diaphoresis (choice C) is excessive sweating and is not a direct symptom of hyperglycemia. Tachycardia (choice D) is increased heart rate and is not a primary finding in hyperglycemia.

Correct Answer: C

Rationale: The correct intervention for a client with COPD is to teach pursed-lip breathing. This technique helps improve oxygenation and reduce dyspnea by promoting better air exchange in the lungs. Encouraging deep breaths may not be suitable for clients with COPD as it can lead to air trapping. Administering oxygen is important in COPD, but teaching pursed-lip breathing is a more direct intervention to help the client manage their condition. Limiting fluid intake is not a standard intervention for COPD and may not be relevant to improving respiratory status.

Correct Answer: B

Rationale: The correct answer is B because the client should exhale quickly and forcefully into the peak flow meter after taking a deep breath to measure peak expiratory flow. Choice A is incorrect as blowing as hard as possible may not provide an accurate reading. Choice C is incorrect because inhaling deeply before blowing can affect the results. Choice D is incorrect as holding the breath before exhaling is not part of using a peak flow meter.

Correct Answer: D

Rationale: Elevating the affected extremity is crucial in managing deep vein thrombosis (DVT) as it helps reduce swelling and promotes venous return, thereby preventing further complications such as pulmonary embolism. Massaging the affected extremity can dislodge a clot and lead to serious consequences. While ambulation is important, in DVT, early ambulation without elevation can potentially dislodge the clot. Warm compresses can increase blood flow to the area and worsen the condition by promoting clot dislodgement.
