Which of the following is a priority nursing action before administering furosemide (Lasix)?
A. Monitor blood glucose levels
B. Check potassium levels
C. Assess for signs of hypoglycemia
D. Encourage the patient to take with food

Which electrolyte imbalance is most common with hydrochlorothiazide? A. Hyperkalemia
B. Hypercalcemia
C. Hypermagnesemia
D. Hyponatremia
Answer: B (Thiazides cause potassium and magnesium loss but increase calcium reabsorption.)

C. Hypoglycemia
D. Hyperkalemia
Answer: A (Amlodipine, a calcium channel blocker, commonly causes peripheral edema.)
- Anticoagulants (Warfarin, Heparin)
Which lab value should be monitored for a patient on warfarin?

❌ C. “Stop taking this medication immediately if you feel better.”
✅ D. “This drug lowers blood pressure and slows the heart rate.”
❌ E. “This medication is safe to use in patients with asthma.”
Correct Answers: A, B, D (Beta-blockers can cause fatigue and dizziness, lower HR/BP, and should not be stopped suddenly.)
- Digoxin Toxicity
A nurse is assessing a patient for digoxin toxicity. Which signs and symptoms indicate toxicity? (Select all that apply.)
A. Nausea and vomiting
B. Yellow-green vision changes
C. Bradycardia
D. Hypertension
E. Confusion
✅ A. Nausea and vomiting
✅ B. Yellow-green vision changes
✅ C. Bradycardia
❌ D. Hypertension

Correct Answers: A, B, C, E (Digoxin toxicity causes GI symptoms, visual disturbances, bradycardia, and confusion.)
- Prioritization: Heparin Infusion
A nurse is monitoring a patient on a heparin drip. Which finding requires immediate intervention?
A. INR of 2.5
B. aPTT of 90 seconds
C. Mild bruising on the arms
D. Hemoglobin of 14 g/dL
Answer: B (A high aPTT (>80 sec) increases bleeding risk.)

A. Titrating a heparin drip
B. Assessing for digoxin toxicity
C. Administering a scheduled subcutaneous enoxaparin injection
D. Educating a patient about warfarin therapy
Answer: C (LPNs can administer injections but cannot titrate IV meds or educate on new meds.)
- Mechanism of Action
Which of the following best describes the mechanism of action of thiazide diuretics?
A. They inhibit the Na⁺/K⁺/2Cl⁻ cotransporter in the loop of Henle.
B. They block aldosterone receptors in the collecting duct.
C. They inhibit sodium-chloride (Na⁺/Cl⁻) reabsorption in the distal convoluted tubule.
D. They prevent the conversion of angiotensin I to angiotensin II.
Answer: C (Thiazide diuretics inhibit Na⁺/Cl⁻ symporters in the distal convoluted tubule, leading to increased sodium and water excretion.)
