1. A postoperative client is four hours after abdominal surgery and
suddenly reports severe shortness of breath and chest pain. The
client is restless, has a respiratory rate of 32/min, oxygen saturation
of 86% on room air, and a heart rate of 124/min. Which action
should the LPN take first?
A. Encourage the client to cough and deep breathe
B. Place the client in high-Fowler's position and administer oxygen as
prescribed
C. Obtain a complete pain history
D. Encourage the client to ambulate
Answer: B. Place the client in high-Fowler's position and administer
oxygen as prescribed
Rationale: The client has signs of acute hypoxemia and possible
pulmonary embolism. Airway and breathing take priority. Positioning
the client upright improves lung expansion, while oxygen addresses
the immediate hypoxemia. The LPN should then promptly notify the
RN/provider and continue assessment.
2. A client with heart failure is prescribed furosemide. Which
laboratory value is most important for the LPN to monitor?
1
,A. Serum potassium
B. Serum calcium
C. Hemoglobin
D. Platelet count
Answer: A. Serum potassium
Rationale: Furosemide is a loop diuretic that can cause significant
potassium loss. Hypokalemia increases the risk of dysrhythmias and
muscle weakness. Potassium should therefore be monitored closely,
especially in clients receiving ongoing or high-dose therapy.
3. A client receiving digoxin reports nausea, anorexia, and seeing
yellow-green halos around lights. What should the LPN recognize?
A. Expected therapeutic effects
B. Digoxin toxicity
C. Hyperglycemia
D. Dehydration
Answer: B. Digoxin toxicity
Rationale: Gastrointestinal symptoms, anorexia, visual disturbances
such as yellow or green halos, and dysrhythmias are classic
manifestations of digoxin toxicity. The medication should be withheld
and the RN/provider notified according to facility policy.
4. Before administering digoxin to an adult client, the LPN obtains
an apical pulse of 52/min. What is the best action?
A. Administer the medication because the pulse is regular
B. Administer half the prescribed dose
C. Hold the medication and notify the RN/provider according to protocol
D. Give the medication with food
2
,Answer: C. Hold the medication and notify the RN/provider
according to protocol
Rationale: Digoxin can slow the heart rate. A significantly low apical
pulse is a reason to withhold digoxin and obtain further direction. The
LPN should not independently alter the prescribed dose.
5. A client with diabetes mellitus becomes pale, shaky, sweaty, and
confused. The client's blood glucose is 48 mg/dL, and the client is
awake and able to swallow. What should the LPN do first?
A. Administer regular insulin
B. Give approximately 15 g of rapid-acting carbohydrate
C. Have the client exercise
D. Restrict oral fluids
Answer: B. Give approximately 15 g of rapid-acting carbohydrate
Rationale: The client has symptomatic hypoglycemia and is able to
swallow safely. Rapid-acting carbohydrate such as glucose tablets or
juice should be given, followed by reassessment of blood glucose.
Insulin would worsen the hypoglycemia.
6. A client with COPD has an oxygen prescription. Which oxygen-
delivery approach is generally appropriate when oxygen is
prescribed cautiously for a client at risk for carbon-dioxide
retention?
A. Apply the highest possible oxygen concentration immediately
B. Use the prescribed low-flow oxygen and closely monitor respiratory
status
C. Withhold oxygen because COPD clients should never receive it
D. Place the client on room air
3
, Answer: B. Use the prescribed low-flow oxygen and closely monitor
respiratory status
Rationale: Oxygen should not be withheld from a hypoxemic client. In
some COPD clients with chronic carbon-dioxide retention, oxygen is
administered carefully at the prescribed concentration while oxygen
saturation, respiratory effort, mental status, and other clinical
indicators are monitored.
7. A client with pneumonia has a respiratory rate of 30/min, oxygen
saturation of 89%, temperature of 39°C, and increasing confusion.
Which finding requires the most immediate attention?
A. Fever
B. Confusion with hypoxemia
C. Productive cough
D. Fatigue
Answer: B. Confusion with hypoxemia
Rationale: Acute mental-status changes in a client with low oxygen
saturation may indicate inadequate oxygenation and clinical
deterioration. Airway and breathing take priority over fever and
routine symptoms.
8. A client receiving a blood transfusion develops chills, fever, low-
back pain, and anxiety 15 minutes after the transfusion begins.
What is the priority action?
A. Slow the transfusion
B. Stop the transfusion immediately
C. Increase the transfusion rate
D. Give acetaminophen and continue the transfusion
