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
,(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
, 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.
