6free samples below
Question 1 Multiple choice hard
A client with heart failure has a BNP of 850 pg/mL. The nurse interprets this as:
- A.Normal value
- B.Indicates significant volume overload and ventricular stretch
- C.Indicates dehydration
- D.Indicates acute MI
Show answer and rationale
Correct answer: B · BNP interpretation
BNP > 400 pg/mL strongly suggests heart failure exacerbation. BNP rises with ventricular wall stretch from volume overload.
Question 2 Multiple choice hard
A client post-cardiac catheterization via right femoral artery suddenly reports back pain and is hypotensive. The nurse should suspect:
- A.Vasovagal response
- B.Retroperitoneal hemorrhage
- C.Pneumothorax
- D.MI extension
Show answer and rationale
Correct answer: B · Post-cath complications
Retroperitoneal bleed is a serious post-cath complication: back/flank pain, hypotension, tachycardia. Notify provider immediately.
Question 3 Multiple choice hard
A nurse notes a client's rhythm has changed to ventricular fibrillation on the monitor. The client is unresponsive and pulseless. What is the priority action?
- A.Administer amiodarone IV
- B.Begin chest compressions and prepare to defibrillate
- C.Place a nasal cannula at 4 L/min
- D.Insert a peripheral IV
Show answer and rationale
Correct answer: B · V-fib — ACLS
V-fib is a shockable rhythm. ACLS: high-quality CPR + immediate defibrillation. Drugs follow only after first shock.
Question 4 Multiple choice hard
A nurse is caring for a client with a chest tube for pneumothorax. Which finding requires immediate intervention?
- A.Continuous bubbling in the suction control chamber
- B.Continuous bubbling in the water seal chamber
- C.Tidaling with respirations in the water seal chamber
- D.Drainage of 100 mL serosanguineous fluid in 8 hours
Show answer and rationale
Correct answer: B · Chest tube troubleshooting
Continuous bubbling in the water seal chamber indicates an air leak — assess for loose connections, dressing dislodgement, or worsening pneumothorax.
Question 5 Select all that apply hard
Which interventions are appropriate for a client with increased intracranial pressure? Select all that apply.
- A.Elevate the head of bed 30 degrees, midline neck position
- B.Suction frequently and for prolonged periods
- C.Avoid Valsalva-inducing activities
- D.Maintain quiet, calm environment
- E.Restrict fluids and avoid hypertonic saline
Show answer and rationale
Correct answer: A, C, D · ICP nursing interventions
ICP care: HOB 30° + neutral neck (venous drainage), avoid Valsalva (no straining), quiet environment, brief suctioning only when needed. Hypertonic saline/mannitol may be ordered.
Question 6 Select 4 hard
A 68-year-old client is admitted with sudden chest pain, BP 88/50, HR 124, RR 28, SpO2 88% on RA, cool clammy skin, weak peripheral pulses. ECG shows ST elevation in V1-V4. Which findings indicate cardiogenic shock? Select 4.
- A.Hypotension with narrow pulse pressure
- B.Tachycardia
- C.Cool clammy peripheral skin
- D.Weak peripheral pulses
- E.Bradycardia at 50 bpm
- F.Wide pulse pressure
Show answer and rationale
Correct answer: A, B, C, D · Cardiogenic shock recognition
Cardiogenic shock = pump failure: hypotension (narrow pulse pressure), compensatory tachycardia, poor peripheral perfusion (cool, clammy, weak pulses). Bradycardia and wide pulse pressure are inconsistent.
