CLT Patient Assessment & Clinical Evaluation 2

Question 1

A patient's chart shows a creatinine of 4.2 mg/dL and BUN of 68 mg/dL. Which clinical condition does this pattern most strongly suggest?

Accepted Answer

Chronic kidney disease

Answer

Elevated creatinine and BUN together indicate impaired renal filtration, consistent with chronic kidney disease.

Question 2

When reviewing a patient's CBC, you notice a left shift with toxic granulation in neutrophils. This finding is most associated with:

Accepted Answer

Severe bacterial sepsis

Answer

Left shift with toxic granulation indicates release of immature neutrophils under extreme demand, characteristic of severe bacterial sepsis.

Question 3

A PT/INR result of 3.8 is reported for a patient on warfarin therapy for atrial fibrillation. The most appropriate clinical action is to:

Accepted Answer

Notify the ordering physician immediately

Answer

An INR of 3.8 exceeds the therapeutic range (2.0–3.0) for atrial fibrillation and represents a critical value requiring immediate physician notification.

Question 4

Which laboratory finding would most likely be seen in a patient experiencing syndrome of inappropriate antidiuretic hormone (SIADH)?

Accepted Answer

Hyponatremia with high urine osmolality

Answer

SIADH causes water retention diluting serum sodium (hyponatremia) while the urine remains inappropriately concentrated (high osmolality).

Question 5

A patient presents with jaundice, elevated direct bilirubin, and elevated alkaline phosphatase with near-normal ALT/AST. This pattern is most consistent with:

Accepted Answer

Cholestatic liver disease

Answer

Elevated direct bilirubin and alkaline phosphatase with minimal transaminase elevation points to biliary obstruction or cholestatic disease.
