Question 1

A patient is diagnosed with deep vein thrombosis (DVT). Which nursing intervention is contraindicated?

Accepted Answer

Massaging the affected leg

Answer

Massaging a limb with known or suspected DVT is contraindicated because it can dislodge the thrombus, causing a potentially fatal pulmonary embolism. Elevation, warmth, and anticoagulation are appropriate interventions.

Question 2

Which dietary instruction is most important for a patient taking warfarin?

Accepted Answer

Maintain consistent vitamin K intake and avoid drastic dietary changes

Answer

Warfarin works by inhibiting vitamin K-dependent clotting factors. Sudden large increases in vitamin K intake (from leafy greens) antagonize warfarin and reduce anticoagulation. Consistency is more important than elimination.

Question 3

A patient has a blood urea nitrogen (BUN) of 45 mg/dL and creatinine of 3.2 mg/dL. What condition does this suggest?

Accepted Answer

Renal impairment

Answer

Elevated BUN and creatinine indicate impaired renal filtration. BUN normal range is 7–20 mg/dL and creatinine 0.6–1.2 mg/dL. Both elevated together strongly suggest acute kidney injury or chronic kidney disease.

Question 4

Which finding indicates that a patient's nasogastric tube is properly placed in the stomach?

Accepted Answer

Aspiration of gastric contents with pH 1–5 and confirmation by X-ray

Answer

X-ray remains the gold standard for initial NG tube placement verification. Aspirating gastric contents and checking pH (gastric pH typically 1–5) is used for ongoing verification. Auscultation alone is unreliable.

Question 5

What is the most common complication following coronary artery bypass graft (CABG) surgery?

Accepted Answer

Dysrhythmias, particularly atrial fibrillation

Answer

Atrial fibrillation occurs in 20–40% of patients after CABG, typically on post-operative day 2–4. It results from pericardial inflammation, electrolyte imbalances, and sympathetic stimulation from surgery.
