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
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.

Correct Answer is C
Explanation
A: Expecting some swelling in the hands and feet is incorrect. Furosemide is a diuretic used to reduce fluid buildup, so swelling should decrease, not increase.
B: Taking the medication at bedtime is not recommended because furosemide increases urine output, which can disrupt sleep. It is better to take it in the morning.
C: Eating foods that contain plenty of potassium is important because furosemide can cause potassium loss. Consuming potassium-rich foods helps maintain electrolyte balance and prevent hypokalemia.
D: Taking aspirin if headaches develop is not related to the use of furosemide. The nurse should address headache management separately and ensure the client understands the specific instructions for furosemide use.
Correct Answer is B
Explanation
A: Applying petroleum jelly to the client’s lips after oral care can help prevent dryness and cracking, but it is not the primary action to ensure safety during oral care.
B: Turning the client on his side before starting oral care is the correct action. This position helps prevent aspiration of fluids and secretions during the procedure, ensuring the client’s safety.
C: Using the thumb and index finger to keep the client’s mouth open is not safe or effective. A mouth prop or padded tongue blade should be used instead.
D: Using a stiff toothbrush can cause damage to the gums and oral tissues. A soft-bristled toothbrush is recommended for gentle and effective cleaning.
