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 A

Explanation

A: The nurse should check the medication order again to ensure that the correct medication is being administered. This response addresses the client’s concern and ensures patient safety.

B: Telling the client that this is the medication their doctor wants them to take does not address the client’s concern about the color difference and may not ensure the correct medication is given.

C: While it is true that the same medication can come in different colors, this response does not verify the accuracy of the medication being administered.

D: Explaining the purpose of the medication is important, but it does not address the immediate concern about the color difference and the need to verify the medication.

A. 165 mg/dL B. 35 mg/dL C. 10 mg/dL D. 31 mg/dL

Correct Answer is B

Explanation

A: A BUN level of 165 mg/dL is extremely high and suggests severe dehydration or possible renal failure. This level is far above the normal range and indicates a critical condition.

B: A BUN level of 35 mg/dL is elevated and consistent with dehydration. Dehydration causes the kidneys to reabsorb more water, leading to higher concentrations of urea in the blood.

C: A BUN level of 10 mg/dL is within the normal range and does not indicate dehydration. This level suggests normal kidney function and hydration status.

D: A BUN level of 31 mg/dL is elevated and suggests dehydration. While not as high as 165 mg/dL, it still indicates that the patient is dehydrated and requires intervention.
