NSG 318 EXAM 1
What are the 3 liver enzymes?
Correct Answer:
Aspartate transaminase (AST), Alanine aminotransferase (ALT), Alkaline phosphatase (ALP)
Expert Rationale:
AST, ALT, and ALP are primary biomarkers measured to assess hepatic function. AST and ALT are intracellular enzymes released into the circulation following hepatocellular injury and are crucial for evaluating hepatocellular damage. ALP, while found in the liver, also exists in bone and other tissues and can be elevated in conditions affecting bile flow 2 / 4
(cholestasis). Comprehensive assessment of liver dysfunction relies on evaluating all three in conjunction with clinical presentation.

What method of administration is putting a tablet under the tongue?
Correct Answer:
Sublingual
Expert Rationale:
The sublingual route involves placing medication under the tongue for absorption via the rich vascular supply. This bypasses the gastrointestinal tract and hepatic first-pass metabolism, thus facilitating more rapid and efficient systemic drug availability.

What lab test reflects the function of the kidney?
Correct Answer:
Creatinine
Expert Rationale:
Serum creatinine is a key marker of renal function, as its concentration in blood increases with renal impairment. Because creatinine is primarily 3 / 4
filtered by the glomerulus and only minimally secreted by renal tubules, changes in its concentration are a sensitive indicator of glomerular filtration rate (GFR).

Decreased responsiveness of a drug over the course of therapy is the definition of what?
Correct Answer:
Tolerance
Expert Rationale:
Tolerance refers to a pharmacological phenomenon where sustained drug exposure results in decreased efficacy, requiring higher doses to achieve the same therapeutic effect. It is distinct from dependence or addiction, and can develop with various drug classes, notably opioids and benzodiazepines.
