NSG 3130 FUNDAMENTAL CONCEPTS &
SKILLS FOR NURSING PRACTICE II
COMPREHENSIVE EXAM
1. A nurse is caring for a patient with chronic obstructive pulmonary disease (COPD) who is
receiving oxygen via nasal cannula. Which oxygen flow rate is generally considered the
maximum safe limit to prevent suppressing the patient’s respiratory drive?
A. 12-15 liters per minute
B. 5-6 liters per minute
C. 8-10 liters per minute
D. 2-3 liters per minute
Answer: D
Conceptual Explanation: Patients with COPD often rely on a hypoxic drive to breathe.
High concentrations of oxygen can suppress this drive, leading to hypoventilation. Usually,
2-3 L/min is the recommended limit.
,2. When preparing to administer NPH and Regular insulin in the same syringe, which of the
following sequences is correct?
A. Withdraw NPH first, then Regular.
B. Inject air into NPH, inject air into Regular, withdraw Regular, withdraw NPH.
C. Withdraw Regular first, then NPH, without injecting air first.
D. Inject air into Regular, inject air into NPH, withdraw NPH, withdraw Regular.
Answer: B
Conceptual Explanation: The standard ‘clear before cloudy’ procedure requires injecting
air into the cloudy (NPH) first, then air into the clear (Regular), withdrawing the clear, and
finally withdrawing the cloudy to prevent contamination of the short-acting insulin.
3. A patient is admitted with suspected pulmonary tuberculosis. Which type of isolation
precaution should the nurse implement immediately?
A. Contact precautions
B. Airborne precautions
C. Droplet precautions
D. Protective environment precautions
Answer: B
, Conceptual Explanation: Tuberculosis is transmitted via small droplets that remain
suspended in the air, requiring airborne precautions, including a negative-pressure room
and N95 respirator masks.
4. A nurse is assessing a pressure injury and notes full-thickness skin loss with visible bone
and tendon. The nurse should document this as which stage?
A. Stage 2
B. Stage 3
C. Stage 4
D. Unstageable
Answer: C
Conceptual Explanation: Stage 4 pressure injuries involve full-thickness skin and tissue
loss with exposed or directly palpable fascia, muscle, tendon, ligament, cartilage, or bone.
5. For a patient placed in physical restraints, how often must the nurse perform an
assessment of the patient’s skin integrity and neurovascular status?
A. Once per shift
B. Every 2 hours
C. Every 15 minutes
D. Every 4 hours
Answer: C
