NP3 EXAM 2 UPDATED WITH MOST TESTED QUESTIONS
AND ANSWERS | GRADED A+ | ASSURED SUCCESS WITH
DETAILED RATIONALES
1. Interpretation of Primary Respiratory Acidosis
A patient with COPD exhibits hypoventilation, elevated PaCO₂, and ↓pH. Which of the following is
consistent with respiratory acidosis?
A. Hyperventilation, pH 7.50
B. PaCO₂ 32 mm Hg, HCO₃⁻ 24 mEq/L
C. PaCO₂ 58 mm Hg, pH 7.28 ✅
D. PaCO₂ 20 mm Hg, pH 7.52
Rationale: Respiratory acidosis features hypoventilation → ↑PaCO₂ and ↓pH.
2. Common Causes of Metabolic Alkalosis
All of the following can precipitate metabolic alkalosis except:
A. Prolonged vomiting
B. Nasogastric suction
C. Diarrhea ✅
D. Overuse of loop diuretics
Rationale: Vomiting/NG loss of H⁺ and diuretic-induced H⁺ loss cause alkalosis; diarrhea causes acidosis.
3. Prednisone Education for COPD Exacerbation
Which statement by the client indicates correct understanding of oral prednisone?
A. “I’ll stop it abruptly once I feel better.”
B. “I’ll take with food and taper off as directed.” ✅
C. “I can take it on an empty stomach.”
D. “It won’t affect my blood sugar.”
Rationale: Corticosteroids require food to reduce GI upset and gradual taper to avoid adrenal crisis.
4. Indication for Epoetin Alfa
, ESTUDYR
Epoetin alfa is prescribed for which condition?
A. Hyperthyroidism
B. Thrombocytopenia
C. Anemia of chronic kidney disease ✅
D. Vitamin B₁₂ deficiency
Rationale: Epoetin stimulates RBC production, especially in CKD-related anemia.
5. Acute Sinusitis First-Line Treatment
A 35-year-old with facial pain and purulent nasal discharge for 10 days is diagnosed with acute bacterial
sinusitis. Initial nursing advice includes:
A. Immediate CT scan
B. Apply warm compresses and encourage fluids ✅
C. Two weeks of systemic steroids
D. Institution of nasal decongestant spray indefinitely
Rationale: Supportive care (heat, hydration) is first; decongestant sprays limited to 3 days to avoid
rebound.
6. Nursing Priority for Chest Tube Care
While caring for a client with a newly placed chest tube, the nurse’s highest priority is to:
A. Strip the tubing every hour
B. Ensure the water seal chamber has the correct fluid level ✅
C. Clamp the tube during ambulation
D. Elevate the drainage system above the chest
Rationale: Proper water seal prevents air re-entry; clamping or elevation risks pneumothorax.
7. Signs of Hypocalcemia Post–Thyroidectomy
Which finding most strongly suggests hypocalcemia in a postoperative thyroidectomy client?
A. Bradycardia
B. Tingling around the mouth and positive Chvostek’s sign ✅
C. Elevated blood pressure
D. Dry, scaly skin
Rationale: Neck surgery can injure parathyroids → low Ca²⁺ → neuromuscular excitability and facial
twitch.
