NUR 185 EXAM 2 MOST TESTED QUESTIONS AND
ANSWERS GRADED A+ WITH RATIONALES
1. Before suctioning a ventilated patient, what is the LPN’s priority action?
A. Instill normal saline
B. Hyperoxygenate the patient
C. Turn off the ventilator
D. Lower the head of the bed
Correct Answer: B
Rationale: Hyperoxygenation prevents hypoxia during suctioning.
2. A ventilator alarm continues to sound. What is the FIRST action by the LPN?
A. Silence the alarm
B. Call respiratory therapy
C. Check tubing for kinks or disconnection
D. Increase oxygen flow
Correct Answer: C
Rationale: Mechanical causes must be ruled out first before interventions.
3. Which suctioning practice is CORRECT for ventilated patients?
A. Suction for 20 seconds
B. Instill normal saline
C. Apply suction only while withdrawing catheter
D. Use peroxide for oral care
Correct Answer: C
Rationale: Continuous suction damages mucosa and increases hypoxia risk.
,ESTUDYR
4. Which intervention best prevents ventilator-associated pneumonia (VAP)?
A. Supine positioning
B. Head of bed elevated 30–45°
C. Frequent suctioning
D. IV antibiotics
Correct Answer: B
Rationale: Elevation reduces aspiration risk.
5. Which condition is MOST associated with respiratory acidosis?
A. Anxiety
B. COPD
C. Vomiting
D. Diarrhea
Correct Answer: B
Rationale: CO₂ retention causes respiratory acidosis.
6. Respiratory alkalosis is MOST commonly caused by:
A. Renal failure
B. Diarrhea
C. Hyperventilation
D. Vomiting
Correct Answer: C
Rationale: Excess CO₂ loss raises pH.
7. Which condition leads to metabolic acidosis?
A. Vomiting
B. Diabetic ketoacidosis
C. NG suction
D. Hyperventilation
,ESTUDYR
Correct Answer: B
Rationale: Acid accumulation lowers pH.
8. Metabolic alkalosis is caused by:
A. Diarrhea
B. DKA
C. Prolonged vomiting
D. Renal failure
Correct Answer: C
Rationale: Loss of gastric acid raises pH.
9. A patient with metabolic syndrome should receive which instruction?
A. Increase fatty foods
B. Avoid statins
C. Lose weight and control carbohydrates
D. Stop glucose monitoring
Correct Answer: C
Rationale: Weight loss and diet control reduce insulin resistance.
10. A patient with burns covering 80% of the body requires which PRIORITY
intervention?
A. Oral fluids
B. IV fluid resuscitation
C. Range-of-motion exercises
D. Discharge teaching
Correct Answer: B
Rationale: Massive fluid shifts cause hypovolemic shock.
, ESTUDYR
11. The emergent phase of burns occurs during which time frame?
A. 72 hours–10 days
B. After wound closure
C. First 48 hours
D. After grafting
Correct Answer: C
Rationale: Highest risk for shock and renal failure.
12. During the acute (diuretic) phase of burns, the nurse expects:
A. Oliguria
B. Hyperkalemia
C. High urine output
D. Hypovolemic shock
Correct Answer: C
Rationale: Fluid shifts back into circulation.
13. The goal of the rehabilitation phase of burns is to:
A. Restore fluids
B. Manage shock
C. Prevent infection and restore function
D. Control pain only
Correct Answer: C
14. Which intervention is expected for third-degree burns?
A. Cold compresses
B. Escharotomy
C. Topical NSAIDs
D. Oral antibiotics only
