A nurse is reinforcing teaching with the parent of an infant who is receiving furosemide. The nurse should reinforce with the parent that which of the following laboratory tests will be monitored while the infant is receiving this medication?

Potassium

WBC count

Iron

Amylase

Answer and Explanation

The Correct Answer is A

A. Potassium: Furosemide is a loop diuretic that increases renal excretion of sodium, chloride, and water, which can lead to significant potassium loss. Monitoring serum potassium levels is essential to prevent hypokalemia, which can cause muscle weakness, arrhythmias, and cardiac complications, especially in infants who are more vulnerable to electrolyte imbalances.

B. WBC count: Furosemide does not typically affect white blood cell production or immune function. Monitoring WBC count is not indicated solely for furosemide therapy unless the infant has another condition that requires hematologic surveillance.

C. Iron: Furosemide does not interfere with iron metabolism or absorption. Iron studies are unrelated to diuretic therapy and are not required unless the infant has known anemia or is receiving iron supplementation for another reason.

D. Amylase: Amylase is a pancreatic enzyme monitored in cases of pancreatic disorders or suspected pancreatitis. Furosemide therapy does not directly affect pancreatic function, so amylase measurement is not indicated as part of routine monitoring for this medication.

Correct Answer is D

Explanation

A. "A nurse will insert an IV prior to starting the test.": A nonstress test (NST) is noninvasive and does not require intravenous access. IV insertion is unnecessary unless other procedures or interventions are planned concurrently, so this statement is inaccurate for routine NST preparation.

B. "You should have nothing to eat or drink for 4 hours prior to the test.": Fasting is not required for an NST. In fact, eating can stimulate fetal activity, which may improve the accuracy of the test by eliciting heart rate accelerations in response to movement.

C. "You should expect the test to take a minimum of 2 hours.": A typical NST usually takes 20–40 minutes to complete, depending on fetal activity. Expecting a minimum of 2 hours may unnecessarily alarm the client and does not reflect standard test duration.

D. "You will be asked to press a button when you feel your baby move.": During an NST, the client uses an event marker to indicate fetal movements. This helps correlate accelerations in the fetal heart rate with fetal activity, providing important information about fetal well-being and autonomic function.

A. BUN B. Serum potassium C. PT D. Serum sodium E. INR

Correct Answer is ["C","E"]

Explanation

A. BUN: Blood urea nitrogen is a marker of renal function and is not directly affected by warfarin therapy. While renal function is important for overall medication safety, it does not guide warfarin dosing or anticoagulation monitoring.

B. Serum potassium: Potassium levels are important for cardiac and neuromuscular function but are not influenced by warfarin. Monitoring potassium is unrelated to evaluating the effectiveness or safety of warfarin therapy.

C. PT: Prothrombin time measures the extrinsic and common coagulation pathways, which are directly affected by warfarin. Checking PT before administration helps assess anticoagulation status and the risk of bleeding, allowing for appropriate dose adjustments.

D. Serum sodium: Sodium levels are critical for fluid balance and neurologic function but do not affect warfarin therapy or coagulation. Monitoring sodium is not necessary for safe administration of warfarin.

E. INR: International normalized ratio standardizes PT results to guide warfarin therapy safely. It provides a reliable measure of anticoagulation and bleeding risk, and checking INR before administering warfarin ensures the dose is appropriate for therapeutic anticoagulation.
