A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?

aPTT

INR

WBC count

Answer and Explanation

The Correct Answer is A

A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.

B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.

C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.

D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.

A. Weight loss B. Jaundice C. Bradycardia D. Polyuria

Correct Answer is B

Explanation

A. Weight loss is not a common or serious adverse effect of valproic acid. Valproic acid can cause weight gain, not weight loss.

B. Jaundice is a sign of liver damage, which is a serious and potentially fatal adverse effect of valproic acid. Valproic acid can impair fatty acid metabolism and mitochondrial function, leading to hepatotoxicity and steatosis. The nurse should monitor the client's liver function tests and report any signs of jaundice, such as yellowing of the skin or eyes, dark urine, or clay-colored stools .

C. Bradycardia is not a common or serious adverse effect of valproic acid. Valproic acid can cause cardiac arrhythmias, but they are usually tachycardic, not bradycardic.

D. Polyuria is not a common or serious adverse effect of valproic acid. Valproic acid can cause hypernatremia and hypocalcemia, which can affect urine output, but polyuria is not a specific symptom of these electrolyte imbalances.
