Reference range

Creatinine [0.6 to 1.2 mg/dL (53 to 106 μmol/L)]

Inelastic skin turgor.

Serum creatinine of 3.5 mg/dL (310 μmol/L).

Thin, fragile hand and arm veins.

Answer and Explanation

The Correct Answer is C

B. Inelastic skin turgor may indicate dehydration or aging but does not directly affect drug dosage.
C. Elevated serum creatinine levels indicate impaired renal function, which necessitates a reduced dosage of medications excreted through the kidneys, such as ticarcillin disodium.
D. Thin, fragile veins are a concern for intravenous access but do not affect the medication dosage.
