Correct Answer: C

Rationale: Using a hydrocolloid dressing is the appropriate care for a stage 2 pressure ulcer because it provides a moist healing environment, promotes healing, and helps to prevent infection. Cleaning the area with normal saline (Choice A) is important but not the primary treatment for a stage 2 pressure ulcer. Applying antibiotic ointment (Choice B) may not be necessary unless there is a sign of infection. Changing the dressing daily (Choice D) may disrupt the healing process and is not recommended unless the dressing is soiled or compromised.

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: C

Rationale: When administering enoxaparin for the prevention of DVT, the nurse should inject the medication into the lateral abdominal wall. This site is preferred for subcutaneous injections of enoxaparin to reduce the risk of bleeding or injury. Expelling air bubbles, massaging the injection site, or administering an NSAID for discomfort are not appropriate actions and could lead to complications or ineffective medication delivery.

Correct Answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

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.
