A nurse is reviewing laboratory findings for three clients.
Which of the following laboratory results should the nurse expect for a client who has cirrhosis?
Elevated amylase.
Decreased bilirubin.
Elevated lipase.
Elevated ammonia.
The Correct Answer is D
Choice A rationale:
Elevated amylase is not typically associated with cirrhosis. Amylase is an enzyme produced by the pancreas and salivary glands, and elevated levels are more commonly associated with pancreatic disorders or acute pancreatitis.
Choice B rationale:
Decreased bilirubin is not an expected laboratory finding in cirrhosis. Cirrhosis often leads to impaired liver function, which can result in elevated bilirubin levels, causing jaundice.
Choice C rationale:
Elevated lipase is not a characteristic laboratory finding in cirrhosis. Lipase is an enzyme produced by the pancreas, and elevated levels are more often seen in pancreatic disorders or acute pancreatitis.
Choice D rationale:
The correct choice is D. Elevated ammonia levels are commonly associated with cirrhosis. In cirrhosis, the damaged liver is unable to effectively metabolize ammonia, leading to its accumulation in the blood. Elevated ammonia levels can result in hepatic encephalopathy, a neurological complication often seen in cirrhotic patients.

Correct Answer is A
Explanation
Choice A rationale:
This is the correct answer. Older adults often experience decreased kidney function as a normal part of aging. Medications that are excreted primarily by the kidneys may require dosage adjustments to prevent potential toxicity.
Choice B rationale:
Increased liver function is not a typical physiological change in older adults. Liver function tends to decrease with age, which can affect the metabolism and clearance of certain medications.
Choice C rationale:
Increased metabolism is not a common physiological change in older adults. Metabolic rate tends to decrease with age, which can affect the metabolism of drugs.
Choice D rationale:
While pulmonary function may decrease with age, it is not the primary physiological change to consider when administering medications to older adults. Kidney function is a more critical factor in medication dosing for this population.
Correct Answer is D
Explanation
Choice A rationale:
Hyperglycemia is not typically associated with tranylcypromine, a monoamine oxidase inhibitor (MAOI) MAOIs can affect blood pressure regulation, but hyperglycemia is not a common adverse effect of this medication.
Choice B rationale:
Hematuria (blood in the urine) is not a known adverse effect of tranylcypromine. This symptom is not directly related to the use of MAOIs.
Choice C rationale:
Tinnitus (ringing in the ears) is not a common adverse effect of tranylcypromine. MAOIs can affect the cardiovascular system, but tinnitus is not a typical manifestation.
Choice D rationale:
Tranylcypromine, an MAOI, can cause hypertension (high blood pressure) as an adverse effect due to its ability to inhibit the breakdown of tyramine in the body. When tyramine-rich foods are ingested, there can be a sudden release of norepinephrine, leading to a hypertensive crisis. Therefore, monitoring for hypertension is essential when a client is taking tranylcypromine and has ingested tyramine-rich foods.
