QUESTIONS COMPLETE WITH 100% VERIFIED ANSWERS
1. A client with chronic obstructive pulmonary disease (COPD) has an
oxygen saturation of 88% on room air. Which supplemental oxygen
delivery method should the nurse anticipate initiating?
A. Non-rebreather mask at 15 L/min
B. Simple face mask at 6 L/min
C. Nasal cannula at 2 L/min
D. Venturi mask at 24%
CORRECT ANSWER: C
Rationale: Clients with COPD should receive oxygen cautiously to avoid
eliminating their hypoxic drive. Nasal cannula at 1-3 L/min is the
preferred initial method for COPD patients with mild to moderate
hypoxemia. Higher flow rates or non-rebreather masks could suppress
the respiratory drive. Venturi masks provide precise oxygen
concentrations but are typically used for more severe cases.
2. A nurse is caring for a client with a central venous catheter. Which
sign indicates a possible catheter-related bloodstream infection?
A. Blood pressure 142/88 mmHg
B. Temperature 101.2°F (38.4°C)
C. Heart rate 68 beats per minute
D. Respiratory rate 14 breaths per minute
CORRECT ANSWER: B
,Rationale: Fever is a primary indicator of catheter-related bloodstream
infection. The elevated temperature suggests systemic infection
requiring prompt intervention. The other vital signs are within normal
limits and do not indicate infection. Blood cultures should be obtained
from both the catheter and a peripheral site.
3. A nurse is preparing to administer enoxaparin 40 mg
subcutaneously. Which action is essential for safe administration?
A. Aspirate for blood return before injection
B. Massage the injection site after administration
C. Administer in the abdominal subcutaneous tissue
D. Use a 21-gauge needle for injection
CORRECT ANSWER: C
Rationale: Enoxaparin should be administered subcutaneously in the
abdominal area, alternating sides to reduce bruising. Aspiration is not
recommended as it may cause tissue damage. Massaging the site can
increase bruising and hematoma formation. A smaller gauge needle
(25-27 gauge) is appropriate for subcutaneous injections.
4. A client with heart failure has gained 3 pounds in 2 days. Which
medication should the nurse anticipate administering?
A. Metoprolol
B. Digoxin
C. Furosemide
D. Spironolactone
,CORRECT ANSWER: C
Rationale: Rapid weight gain in heart failure indicates fluid retention.
Furosemide is a loop diuretic that promotes fluid excretion and reduces
preload. Metoprolol is a beta-blocker used for chronic management.
Digoxin improves contractility but does not address fluid overload.
Spironolactone is a potassium-sparing diuretic used in specific cases.
5. The nurse receives a handoff report on four clients. Which client
should the nurse assess first?
A. Client with pneumonia and oxygen saturation of 92%
B. Client with diabetes and blood glucose of 180 mg/dL
C. Client with chest pain rated 6 on a 0-10 scale
D. Client with postoperative nausea requesting antiemetic
CORRECT ANSWER: C
Rationale: Chest pain indicates potential cardiac ischemia requiring
immediate assessment and intervention. The ABCs (Airway, Breathing,
Circulation) and severity of symptoms guide prioritization. Oxygen
saturation of 92% is acceptable for a pneumonia patient. Blood glucose
of 180 mg/dL is elevated but not emergent. Nausea is uncomfortable
but not life-threatening.
6. A nurse is assessing a client's peripheral IV site. Which finding
requires immediate intervention?
A. Slight redness at the insertion site
B. Warmth and tenderness along the vein
, C. Small amount of clear drainage
D. Bruising around the insertion site
CORRECT ANSWER: B
Rationale: Warmth and tenderness along the vein suggest phlebitis or
infection requiring immediate discontinuation of the IV. Slight redness
may be normal. Clear drainage could indicate serous fluid. Bruising is
common from the insertion process. The IV should be removed and
restarted in another location.
7. A client with a tracheostomy has thick, tenacious secretions. Which
intervention should the nurse implement first?
A. Suction the tracheostomy
B. Instill 5 mL of normal saline
C. Increase humidification
D. Perform chest physiotherapy
CORRECT ANSWER: C
Rationale: Increasing humidification helps thin secretions, making them
easier to clear. Suctioning should only be performed when necessary.
Saline instillation is controversial and may introduce infection. Chest
physiotherapy may be helpful but is not the first intervention for thick
secretions.
8. The nurse is caring for a client with an NG tube. Which assessment
finding indicates proper tube placement?
