Question 1: A practical nurse is preparing to administer oral medication to a client
who has difficulty swallowing. Which action should the nurse take first?
A. Crush the medication and mix it with applesauce
B. Offer the client a large amount of water to facilitate swallowing
C. Assess the client's ability to swallow safely
D. Request a prescription for an alternative route of administration
CORRECT ANSWER: C. Assess the client's ability to swallow safely
RATIONALE: Before administering any oral medication to a client with swallowing
difficulties, the nurse must first assess the client's swallow reflex and safety to prevent
aspiration. Assessment is the initial step in the nursing process and guides all
subsequent interventions. Crushing medications or altering the route requires a
provider's order and should not be done without assessment and approval.
Question 2: Which finding should a practical nurse recognize as an early sign of
hypoxia in a client with chronic obstructive pulmonary disease (COPD)?
A. Cyanosis of the lips and nail beds
B. Restlessness and confusion
C. Bradycardia and hypotension
D. Decreased respiratory rate
CORRECT ANSWER: B. Restlessness and confusion
RATIONALE: Early signs of hypoxia include restlessness, anxiety, confusion, and
tachycardia as the brain responds to decreased oxygen levels. Cyanosis is a late sign of
hypoxia. Bradycardia and decreased respiratory rate indicate severe, life-threatening
deterioration, not early hypoxia.
Question 3: A practical nurse is caring for a client who is prescribed warfarin.
Which laboratory value should the nurse monitor to evaluate the therapeutic effect
of this medication?
A. Platelet count
B. International normalized ratio (INR)
C. Activated partial thromboplastin time (aPTT)
D. Hemoglobin and hematocrit
CORRECT ANSWER: B. International normalized ratio (INR)
RATIONALE: Warfarin is an oral anticoagulant that works by inhibiting vitamin K-
dependent clotting factors. The INR standardizes prothrombin time results and is the
primary laboratory test used to monitor warfarin therapy. The therapeutic INR range for
,most conditions is 2.0 to 3.0. aPTT monitors heparin therapy, while platelet count and
hemoglobin/hematocrit assess for bleeding complications but not therapeutic effect.
Question 4: When performing hand hygiene, which action by a practical nurse
indicates correct technique when using an alcohol-based hand rub?
A. Rinsing hands with water after applying the product
B. Rubbing hands together until they are dry
C. Using a paper towel to turn off the faucet
D. Applying the product to damp hands
CORRECT ANSWER: B. Rubbing hands together until they are dry
RATIONALE: When using an alcohol-based hand rub, the nurse should apply the
recommended amount and rub hands together, covering all surfaces, until the hands
are completely dry. This ensures adequate contact time for microbial kill. Alcohol-
based hand rubs do not require water rinsing. Using a paper towel to turn off the faucet
applies to soap-and-water handwashing, and the product should be applied to dry
hands for optimal effectiveness.
Question 5: A practical nurse is assisting with the care of a client who has a
nasogastric tube connected to low intermittent suction. Which finding should the
nurse report to the registered nurse immediately?
A. Greenish-yellow gastric aspirate
B. Client reports mild thirst
C. Abdominal distension and absence of bowel sounds
D. Small amount of drainage in the collection canister
CORRECT ANSWER: C. Abdominal distension and absence of bowel sounds
RATIONALE: Abdominal distension with absent bowel sounds may indicate ileus, bowel
obstruction, or improper NG tube placement/function, requiring immediate evaluation.
Greenish-yellow aspirate is expected gastric content. Mild thirst is common with NG
tubes and can be managed with oral care. Small amounts of drainage are expected with
suction.
Question 6: Which statement by a client newly diagnosed with diabetes mellitus
indicates a need for further teaching about foot care?
A. "I will inspect my feet daily for cuts or blisters."
B. "I can walk barefoot inside my home to strengthen my feet."
C. "I will wear well-fitting shoes and clean socks every day."
D. "I should avoid using heating pads on my feet."
CORRECT ANSWER: B. "I can walk barefoot inside my home to strengthen my feet."
RATIONALE: Clients with diabetes should never walk barefoot, even indoors, due to
decreased sensation and increased risk of injury and infection. Daily foot inspection,
,wearing protective footwear, and avoiding extreme temperatures are essential
components of diabetic foot care education.
Question 7: A practical nurse is preparing to administer a subcutaneous injection
of heparin. Which action should the nurse take to minimize tissue irritation?
A. Massage the injection site after administration
B. Aspirate before injecting the medication
C. Inject the medication slowly without aspirating
D. Apply firm pressure to the site for 1 minute after injection
CORRECT ANSWER: C. Inject the medication slowly without aspirating
RATIONALE: For subcutaneous heparin injections, the nurse should not aspirate or
massage the site, as this can cause tissue trauma, bruising, or hematoma formation.
The medication should be injected slowly to minimize discomfort. Applying gentle
pressure without rubbing may be done if bleeding occurs, but firm pressure is not
routinely required.
Question 8: Which finding in a client receiving intravenous therapy should a
practical nurse recognize as indicative of phlebitis?
A. Coolness and pallor at the insertion site
B. Redness, warmth, and tenderness along the vein
C. Swelling and leakage of fluid at the site
D. Blood return in the IV tubing
CORRECT ANSWER: B. Redness, warmth, and tenderness along the vein
RATIONALE: Phlebitis is inflammation of the vein, characterized by redness, warmth,
tenderness, and sometimes a palpable cord along the vein path. Coolness and pallor
suggest infiltration or compromised circulation. Swelling and leakage indicate
infiltration. Blood return confirms patency but does not rule out phlebitis.
Question 9: A practical nurse is caring for a client who is prescribed furosemide.
Which assessment finding should the nurse prioritize?
A. Daily weight measurement
B. Serum potassium level
C. Blood pressure reading
D. Urine output volume
CORRECT ANSWER: B. Serum potassium level
RATIONALE: Furosemide is a loop diuretic that causes potassium excretion, placing the
client at high risk for hypokalemia, which can lead to life-threatening cardiac
dysrhythmias. While daily weight, blood pressure, and urine output are important
assessments for diuretic therapy, electrolyte imbalances pose the most immediate
physiological risk and require priority monitoring.
, Question 10: When documenting care in a client's medical record, which action by
a practical nurse demonstrates adherence to legal guidelines?
A. Using abbreviations approved by the facility
B. Documenting care at the end of the shift from memory
C. Correcting an error by drawing a single line through it and initialing
D. Recording subjective opinions about the client's behavior
CORRECT ANSWER: C. Correcting an error by drawing a single line through it and
initialing
RATIONALE: Legal documentation standards require errors to be corrected by drawing
a single line through the mistake, writing "error" or "mistaken entry," and initialing and
dating the correction. This maintains an auditable trail. Only facility-approved
abbreviations should be used. Documentation should be timely and factual, not
delayed or based on memory, and must exclude subjective opinions or judgments.
Question 11: A practical nurse is assisting a client who is on bed rest to use a
bedpan. Which action should the nurse take to promote the client's comfort and
dignity?
A. Place the bedpan under the client while the client lifts their hips
B. Provide privacy and explain each step of the procedure
C. Keep the side rails down during the procedure for easy access
D. Empty the bedpan immediately in front of the client
CORRECT ANSWER: B. Provide privacy and explain each step of the procedure
RATIONALE: Maintaining dignity and reducing embarrassment during intimate care
procedures requires providing privacy, explaining actions, and involving the client in
care. While assisting with hip lifting may be necessary, the priority is communication
and respect. Side rails should be managed according to safety protocols, and emptying
the bedpan should be done discreetly after the client is comfortable.
Question 12: Which instruction should a practical nurse include when teaching a
client about proper use of an incentive spirometer?
A. "Exhale forcefully into the mouthpiece before inhaling."
B. "Inhale slowly and deeply to raise the indicator to the target zone."
C. "Use the spirometer only when you feel short of breath."
D. "Hold your breath for 10 seconds after exhaling."
CORRECT ANSWER: B. "Inhale slowly and deeply to raise the indicator to the target
zone."
RATIONALE: Proper incentive spirometer use involves sitting upright, exhaling normally,
placing the mouthpiece securely, and inhaling slowly and deeply to elevate the piston or
balls to the prescribed target, then holding the breath briefly before exhaling. This
