The nurse closely monitors an older adult for signs of medication toxicity. Which physiological change is the reason for the nurse’s action?

Renal dysfunction

Pancreatic impairment

Increased gastric motility

Increased blood volume

Answer and Explanation

The Correct Answer is A

A: Renal dysfunction is common in older adults and can lead to decreased clearance of medications from the body, increasing the risk of toxicity. Monitoring for signs of toxicity is crucial in this population.

B: Pancreatic impairment can affect digestion and insulin production but is not the primary reason for monitoring medication toxicity in older adults.

C: Increased gastric motility is not typically associated with aging. In fact, decreased gastric motility is more common and can affect drug absorption.

D: Increased blood volume is not a common physiological change in older adults. Decreased renal function and changes in body composition are more relevant factors affecting medication metabolism and excretion.

A. Consult a dietitian. B. Apply a hydrogel dressing. C. Clean the wound with hydrogen peroxide. D. Use a low-air-loss therapy unit.

Correct Answer is C

Explanation

The correct answer is C.

A: Consulting a dietitian is a beneficial order for a patient with a pressure ulcer. Proper nutrition, especially adequate protein intake, is crucial for wound healing. A dietitian can help ensure the patient receives the necessary nutrients to support tissue repair and recovery.

B: Applying a hydrogel dressing is appropriate for a clean, granulating Stage II pressure ulcer. Hydrogel dressings maintain a moist wound environment, which promotes healing and provides pain relief. They are suitable for wounds with minimal to moderate exudate.

C: Cleaning the wound with hydrogen peroxide is not recommended for a healing pressure ulcer. Hydrogen peroxide can damage healthy granulating tissue and delay the healing process. It is better to use saline or a wound cleanser that does not harm the new tissue.

D: Using a low-air-loss therapy unit is beneficial for patients with pressure ulcers. These units help reduce pressure on the skin, improve circulation, and prevent further skin breakdown. They are an effective part of pressure ulcer management.
