NR 341 – Complex Adult Health Midterm
Exam (Exam 2) Questions and Answers
with Rationales 2025
• Hemodynamics
• Shock (Septic, Hypovolemic, Cardiogenic)
• Burns
• Respiratory Failure
• Mechanical Ventilation
• MODS (Multiple Organ Dysfunction Syndrome)
• Dysrhythmias
• Cardiovascular emergencies
1. A client with chronic obstructive pulmonary disease (COPD) is receiving
oxygen therapy. Which oxygen delivery device is most appropriate for this
client?
A. Non-rebreather mask
B. Simple face mask
,C. Nasal cannula
D. Venturi mask
Correct Answer: D. Venturi mask
Rationale: The Venturi mask delivers precise oxygen concentrations and is ideal
for COPD clients to avoid suppressing the respiratory drive.
2. A client with heart failure is receiving furosemide IV. What is the priority
assessment?
A. Blood glucose
B. Apical pulse
C. Serum potassium
D. Bowel sounds
Correct Answer: C. Serum potassium
Rationale: Furosemide is a loop diuretic that can cause hypokalemia. Monitor
potassium to prevent dysrhythmias.
3. Which ECG change is associated with hypokalemia?
A. Peaked T waves
B. Prolonged PR interval
C. ST depression
D. Wide QRS complex
, Correct Answer: C. ST depression
Rationale: Hypokalemia commonly causes ST depression, flattened T waves, and
the appearance of U waves.
4. A nurse finds a patient post-op with a sudden onset of dyspnea, tachycardia,
and sharp chest pain. What is the most likely cause?
A. Pulmonary embolism
B. Myocardial infarction
C. Pneumonia
D. Pleural effusion
Correct Answer: A. Pulmonary embolism
Rationale: Sudden dyspnea, chest pain, and tachycardia post-op suggest a PE, a
critical complication of immobility or DVT.
5. Which sign is an early indicator of hypovolemic shock?
A. Bradycardia
B. Cold, mottled skin
C. Increased urine output
D. Restlessness
Correct Answer: D. Restlessness
Rationale: Early hypoxia from shock affects the brain first, leading to restlessness
and anxiety.
