,**Q1. A nurse is administering IV furosemide to a client with acute decompensated heart failure. Which
assessment finding requires immediate intervention?**
- A) Urine output of 250 mL in 2 hours
- **B) Serum potassium 3.1 mEq/L**
- C) Blood pressure 110/68 mm Hg
- D) Mild tinnitus
**Correct Answer: B**
**Rationale:** Furosemide is a loop diuretic that causes potassium wasting. A serum potassium of 3.1
mEq/L is below the normal range (3.5-5.0) and indicates **hypokalemia**, which predisposes the client
to cardiac arrhythmias and digoxin toxicity. This finding requires immediate intervention .

**Q2. A client taking warfarin has an INR of 5.2. The client denies bleeding. Which action should the
nurse anticipate?**
- A) Administer protamine sulfate
- **B) Administer vitamin K orally**
- C) Hold warfarin and monitor only
- D) Increase the warfarin dose
,**Correct Answer: B**
**Rationale:** An INR >4.0 places the client at high risk for bleeding even without active bleeding.
Vitamin K (phytonadione) is the antidote to reverse warfarin effects. Protamine sulfate reverses heparin,
not warfarin .

**Q3. A nurse is teaching a client about digoxin toxicity. Which client statement indicates a need for
further teaching?**
- A) "I will report nausea and vomiting to my doctor."
- **B) "I can take an antacid if I have heartburn."**
- C) "I will check my pulse before taking the medication."
- D) "Yellow halos around lights are a sign of toxicity."
**Correct Answer: B**
**Rationale:** Antacids can decrease digoxin absorption and increase the risk of toxicity by altering GI
motility. Clients should consult their provider before taking antacids or other OTC medications while on
digoxin .

**Q4. A client is prescribed enoxaparin 40 mg subcutaneously daily. Which action is correct?**
- A) Expel the air bubble from the prefilled syringe
- B) Massage the site after injection
- **C) Insert the needle into a skin fold at a 90° angle**
, - D) Aspirate before injecting
**Correct Answer: C**
**Rationale:** Enoxaparin (low molecular weight heparin) is given subcutaneously. The air bubble
should **not** be expelled. The site should **not** be massaged. Aspiration is **not** required. The
needle is inserted at a 90° angle into a skin fold on the abdomen .
---
**Q5. A nurse reviews a client's morning laboratory results and finds a potassium level of 5.8 mEq/L.
The client takes spironolactone. Which is the priority action?**
- A) Encourage banana and orange intake
- B) Administer the next spironolactone dose
- **C) Hold spironolactone and notify the provider**
- D) Give IV calcium gluconate
**Correct Answer: C**
**Rationale:** Spironolactone is a potassium-sparing diuretic. A potassium level of 5.8 mEq/L is severely
elevated and places the client at risk for cardiac arrhythmias. The nurse should hold the next dose and
notify the provider immediately .
---
**Q6. A client receiving a heparin infusion has an aPTT of 110 seconds (normal 25-35). Which
medication should the nurse prepare?**
- A) Vitamin K
