NR 341 – Complex Adult Health Midterm
Exam (Exam 2) 50 Questions and Answers
with Rationales 2025\2026 update
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
ANS>>: 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
ANS>>: 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
, ANS>>: 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
ANS>>: 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
ANS>>: D. Restlessness
Rationale: Early hypoxia from shock affects the brain first, leading to restlessness
and anxiety.
