1. A nurse is caring for a client diagnosed with acute heart failure who has crackles in the A
nurse is caring for a client with chronic heart failure who reports sudden weight gain
and increased shortness of breath. Which finding requires immediate intervention?
a. Weight gain of 1 lb (0.45 kg) in 24 hours
b. Bilateral ankle edema
c. Respiratory rate of 22/min
d. Mild fatigue on exertion
✔️ Correct Answer: a. Weight gain of 1 lb (0.45 kg) in 24 hours
Rationale:
A rapid weight gain of 1 lb in 24 hours in a heart failure client suggests acute fluid
retention and possible worsening heart failure, requiring prompt intervention. This may
indicate early decompensation before overt respiratory distress occurs. Bilateral edema,
mild tachypnea, and fatigue are expected chronic findings and do not indicate
immediate deterioration. NCLEX focus: Early recognition of fluid overload in heart
failure.
,A nurse is assessing a client with diabetic ketoacidosis (DKA). Which finding is most
expected?
a. Slow, shallow respirations
b. Fruity-smelling breath
c. Hypoglycemia
d. Bradycardia
✔️ Correct Answer: b. Fruity-smelling breath
Rationale:
DKA leads to metabolic acidosis, triggering Kussmaul respirations and a fruity or
acetone breath odor due to ketone accumulation. Patients are typically hyperglycemic,
not hypoglycemic. Tachycardia, not bradycardia, is more common due to dehydration.
NCLEX focus: Recognition of DKA manifestations.
A nurse is caring for a client receiving heparin therapy. Which lab value should the nurse
monitor?
a. INR
b. aPTT
c. Platelet count only
d. Hemoglobin A1C
✔️ Correct Answer: b. aPTT
Rationale:
Heparin therapy is monitored using activated partial thromboplastin time (aPTT) to
evaluate therapeutic effect and bleeding risk. INR is used for warfarin therapy. Platelet
count is important for monitoring HIT but not therapeutic dosing. Hemoglobin A1C
reflects glucose control, not anticoagulation. NCLEX focus: Anticoagulant monitoring.
A client presents with chest pain and ST elevation on ECG. What is the priority nursing
action?
a. Obtain a full dietary history
b. Administer oxygen and notify provider
,c. Encourage ambulation
d. Reassess in 1 hour
✔️ Correct Answer: b. Administer oxygen and notify provider
Rationale:
ST elevation indicates myocardial infarction. Immediate oxygen administration and
provider notification are priority actions to reduce myocardial ischemia. Delays in
intervention increase cardiac tissue death. Ambulation and dietary history are not
priorities in acute MI. NCLEX focus: Acute coronary syndrome management.
A nurse is caring for a client with hyperkalemia. Which ECG change is most expected?
a. U waves
b. Tall peaked T waves
c. ST depression
d. Prolonged QT interval
✔️ Correct Answer: b. Tall peaked T waves
Rationale:
Hyperkalemia causes tall, peaked T waves due to altered cardiac conduction. U waves
are associated with hypokalemia. Prolonged QT and ST depression are not primary
features of elevated potassium. NCLEX focus: Electrolyte imbalance recognition.
A nurse is caring for a client with COPD. Which oxygen delivery method is most
appropriate?
a. Non-rebreather mask at 15 L/min
b. Venturi mask at prescribed FiO₂
c. Nasal cannula at 10 L/min
d. Room air only
✔️ Correct Answer: b. Venturi mask at prescribed FiO₂
Rationale:
Clients with COPD require controlled oxygen delivery to avoid suppressing hypoxic
drive. A Venturi mask provides precise oxygen concentrations. High-flow non-rebreather
, masks may cause CO₂ retention. Nasal cannula at high flow is inappropriate. NCLEX
focus: Oxygen therapy in chronic lung disease.
A nurse is caring for a client with acute kidney injury (AKI). Which lab finding is most
concerning?
a. Elevated BUN and creatinine
b. Decreased potassium
c. Low urine specific gravity
d. Decreased sodium intake
✔️ Correct Answer: a. Elevated BUN and creatinine
Rationale:
AKI is characterized by decreased renal filtration leading to elevated BUN and creatinine.
Hyperkalemia, not hypokalemia, is more common. Low urine specific gravity may occur
but is less critical than worsening renal function markers. NCLEX focus: Renal failure
recognition.
A nurse is caring for a client experiencing a stroke. Which assessment finding requires
immediate action?
a. Slurred speech
b. Unilateral weakness
c. Sudden loss of vision
d. Headache rated 4/10
✔️ Correct Answer: c. Sudden loss of vision
Rationale:
Sudden vision loss suggests cerebral ischemia affecting the visual cortex or retinal
circulation and may indicate worsening stroke. All neurological deficits are important,
but sudden changes in vision may indicate evolving stroke territory involvement
requiring urgent evaluation. NCLEX focus: Stroke recognition and escalation.
