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.

Correct Answer is B

Explanation

A: Completing proper documentation of the medication error is important but should not be the first action. Immediate assessment of the patient is more critical.

B: Returning to the room to check and assess the patient is the first priority. The nurse needs to determine if the patient has experienced any adverse effects from the medication error and provide appropriate care.

C: Administering the antidote to the patient immediately is only necessary if the medication given has a known antidote and the patient is showing signs of adverse effects. Assessment should come first.

D: Alerting the charge nurse that a medication error has occurred is important for reporting and follow-up but should follow the immediate assessment and care of the patient.

A. Hypertension B. Tachycardia C. Pallor D. Bradypnea

Correct Answer is C

Explanation

A: Hypertension is not typically a late sign of hypoxemia. It can occur in various conditions but is not specific to hypoxemia.

B: Tachycardia is an early sign of hypoxemia as the body attempts to compensate for low oxygen levels by increasing the heart rate.

C: Pallor is a late sign of hypoxemia. It indicates poor oxygenation and perfusion, often seen when the body can no longer compensate for the lack of oxygen.

D: Bradypnea, or slow breathing, is not a typical sign of hypoxemia. Hypoxemia usually causes an increase in respiratory rate (tachypnea) as the body tries to take in more oxygen.
