1. A client with chronic obstructive pulmonary disease (COPD) is receiving
oxygen therapy. Which oxygen delivery device is best for a client who needs a
precise oxygen concentration?
a) Nasal cannula
b) Simple face mask
c) Venturi mask
d) Non-rebreather mask
Answer: c) Venturi mask
Rationale: The Venturi mask delivers a precise oxygen concentration by mixing
oxygen with room air. It is preferred when exact oxygen percentages are
needed.
,2. A nurse is caring for a client with diabetes mellitus who is experiencing
hypoglycemia. Which symptom is most indicative of hypoglycemia?
a) Polyuria
b) Tremors and sweating
c) Blurred vision
d) Fruity breath odor
Answer: b) Tremors and sweating
Rationale: Tremors and sweating are classic signs of hypoglycemia due to
sympathetic nervous system activation. Fruity breath odor is associated with
diabetic ketoacidosis.
3. The nurse is administering morphine sulfate to a postoperative client. Which
assessment finding would require immediate intervention?
a) Respiratory rate 10/min
b) Pupils constricted
c) Blood pressure 130/80 mmHg
d) Pulse rate 72 bpm
Answer: a) Respiratory rate 10/min
Rationale: Morphine can cause respiratory depression. A respiratory rate below
12/min requires immediate action to prevent respiratory arrest.
,4. When preparing to insert a nasogastric (NG) tube, which of the following
steps should the nurse perform first?
a) Check the client’s gag reflex
b) Measure the length of the tube
c) Lubricate the tip of the tube

the nurse’s best action?
a) Encourage fluid intake
b) Notify the healthcare provider
c) Assess lung sounds
d) Document the finding
Answer: c) Assess lung sounds
Rationale: Rapid weight gain may indicate fluid retention; assessing lung sounds
can identify pulmonary edema, a serious complication.

indicates a healthy stoma?
a) Dark purple color
b) Bright red and moist
, c) Pale and dry
d) Black and necrotic

pressure ulcer?
a) Apply heat to the area
b) Keep the client in a supine position
c) Reposition the client every 2 hours
d) Massage the bony prominences
Answer: c) Reposition the client every 2 hours
Rationale: Frequent repositioning reduces pressure and promotes circulation,
preventing further tissue damage.
8. The nurse is teaching a client about warfarin therapy. Which statement by the
client indicates a need for further teaching?
