Success
Question 1: A practical nurse is preparing to administer medications to a client.
Which action should the nurse take first to ensure client safety?
A. Check the client's allergy band
B. Verify the medication order with another nurse
C. Perform hand hygiene
D. Explain the procedure to the client
CORRECT ANSWER: C. Perform hand hygiene
Rationale: Hand hygiene is the foundational step in infection control and must be
performed before any client contact or medication administration to prevent
transmission of pathogens. While checking allergies, verifying orders, and client
education are important, hand hygiene is the initial action that protects both the client
and nurse from healthcare-associated infections per CDC and WHO guidelines.
Question 2: A client with heart failure is prescribed furosemide 40 mg orally daily.
Which finding should the practical nurse report immediately to the registered
nurse?
A. Weight loss of 1 kg in 24 hours
B. Serum potassium level of 3.2 mEq/L
C. Blood pressure of 110/70 mm Hg
D. Urine output of 1500 mL in 8 hours
CORRECT ANSWER: B. Serum potassium level of 3.2 mEq/L
Rationale: Furosemide is a loop diuretic that causes potassium excretion, putting
clients at risk for hypokalemia. A serum potassium level of 3.2 mEq/L is below the
normal range (3.5-5.0 mEq/L) and can cause life-threatening cardiac dysrhythmias,
muscle weakness, and fatigue. This requires immediate notification for potential
potassium replacement therapy.
Question 3: When providing discharge teaching to a client with type 2 diabetes
mellitus, which statement by the client indicates understanding of hypoglycemia
management?
A. "I will take an extra dose of my insulin if my blood sugar is high."
B. "I will eat 15 grams of fast-acting carbohydrate if I feel shaky."
C. "I should skip my morning medication if I don't feel like eating."
D. "I will check my blood sugar only when I feel symptoms."
,CORRECT ANSWER: B. "I will eat 15 grams of fast-acting carbohydrate if I feel
shaky."
Rationale: The rule of 15 is standard for hypoglycemia management: consume 15
grams of fast-acting carbohydrate (e.g., 4 oz juice, glucose tablets), wait 15 minutes,
and recheck blood glucose. This approach safely raises blood sugar without causing
rebound hyperglycemia. Options A, C, and D represent dangerous misconceptions that
could worsen glycemic control.
Question 4: A practical nurse is caring for a postoperative client who reports pain at
the incision site. Which nonpharmacological intervention should the nurse
implement first?
A. Apply a warm compress to the incision
B. Assist the client to a position of comfort
C. Teach deep breathing exercises
D. Offer distraction techniques
CORRECT ANSWER: B. Assist the client to a position of comfort
Rationale: Positioning is the most immediate, noninvasive intervention to reduce
tension on surgical incisions and alleviate pain. It can be implemented instantly without
additional equipment or teaching. While warm compresses, breathing exercises, and
distraction are beneficial, they are secondary to optimizing physical alignment for pain
relief in the immediate postoperative period.
Question 5: Which action by a practical nurse demonstrates proper technique
when donning sterile gloves for a dressing change?
A. Touching the outside of the glove with bare hands to adjust fit
B. Picking up the second glove by the folded cuff with the gloved hand
C. Allowing gloved hands to fall below waist level during the procedure
D. Using the dominant hand to grasp the inside of the first glove
CORRECT ANSWER: B. Picking up the second glove by the folded cuff with the
gloved hand
Rationale: Sterile technique requires that only sterile surfaces touch sterile surfaces.
After donning the first glove, the gloved hand should pick up the second glove by its
folded cuff (which is considered sterile on the outside) to maintain sterility. Touching
glove exteriors with bare hands, allowing gloves below waist level, or grasping the inside
of gloves contaminates the sterile field.
Question 6: A client with chronic obstructive pulmonary disease (COPD) is
receiving oxygen via nasal cannula at 2 L/min. Which assessment finding requires
immediate intervention?
A. Oxygen saturation of 92%
B. Respiratory rate of 24 breaths/min
,C. Confusion and drowsiness
D. Use of accessory muscles
CORRECT ANSWER: C. Confusion and drowsiness
Rationale: In clients with COPD, high oxygen concentrations can suppress the hypoxic
drive to breathe, leading to carbon dioxide retention, respiratory acidosis, and altered
mental status. Confusion and drowsiness are late signs of hypercapnia and require
immediate assessment of arterial blood gases and oxygen adjustment. While other
findings warrant monitoring, neurological changes indicate acute deterioration.
Question 7: When administering a subcutaneous injection of enoxaparin, which
technique should the practical nurse use?
A. Aspirate before injecting the medication
B. Massage the injection site after administration
C. Pinch a 1- to 2-inch fold of abdominal skin
D. Inject at a 45-degree angle in the deltoid muscle
CORRECT ANSWER: C. Pinch a 1- to 2-inch fold of abdominal skin
Rationale: Enoxaparin, a low-molecular-weight heparin, is administered
subcutaneously in the abdomen (avoiding 2 inches around the umbilicus) with a
pinched skin fold to ensure proper depth and reduce bruising. Aspiration is not
recommended for subcutaneous anticoagulants as it can cause tissue trauma.
Massaging the site increases bruising risk, and deltoid injections are inappropriate for
this medication.
Question 8: A practical nurse is caring for a client with a new colostomy. Which
observation indicates the stoma is viable?
A. Pale pink color
B. Dark purple appearance
C. Moist, beefy-red tissue
D. Dry, blackened edges
CORRECT ANSWER: C. Moist, beefy-red tissue
Rationale: A healthy stoma appears moist and beefy-red due to adequate blood supply.
Pale pink may indicate anemia, while dark purple or black suggests ischemia or
necrosis requiring urgent intervention. Dryness indicates poor perfusion. Monitoring
stoma color, moisture, and temperature is critical in the immediate postoperative
period to detect complications early.
Question 9: Which statement by a client prescribed warfarin indicates the need for
further teaching?
A. "I will use an electric razor instead of a blade."
B. "I will avoid foods high in vitamin K like spinach."
, C. "I will take ibuprofen for headaches."
D. "I will wear a medical alert bracelet."
CORRECT ANSWER: C. "I will take ibuprofen for headaches."
Rationale: Ibuprofen and other NSAIDs increase bleeding risk when combined with
warfarin by inhibiting platelet function and irritating the gastric mucosa.
Acetaminophen is preferred for pain management. Options A, B, and D reflect
appropriate safety measures for anticoagulant therapy. Clients must understand
medication interactions to prevent hemorrhagic complications.
Question 10: A practical nurse is preparing to insert an indwelling urinary catheter
in a female client. Which action maintains surgical asepsis?
A. Cleaning the meatus with a single stroke from front to back
B. Using the dominant hand to hold the catheter during insertion
C. Placing contaminated supplies on the sterile field temporarily
D. Opening sterile packages by peeling edges away from the body
CORRECT ANSWER: D. Opening sterile packages by peeling edges away from the
body
Rationale: Sterile packages should be opened by peeling edges away from the body to
prevent reaching over the sterile field and contaminating contents. For female
catheterization, the meatus is cleaned with multiple strokes (not single) using separate
antiseptic swabs for each stroke, moving front to back. The nondominant hand holds
the labia (considered contaminated) and must not touch sterile catheter parts.
Contaminated items must never contact the sterile field.
Question 11: A client with pneumonia has an oxygen saturation of 88% on room air.
Which intervention should the practical nurse implement first?
A. Administer prescribed bronchodilator
B. Apply oxygen via nasal cannula
C. Encourage deep breathing and coughing
D. Notify the registered nurse immediately
CORRECT ANSWER: B. Apply oxygen via nasal cannula
Rationale: Hypoxemia (SpO2 <90%) requires immediate oxygen supplementation to
prevent tissue damage. Applying oxygen is within the practical nurse's scope and
addresses the most urgent physiological need per ABC (Airway, Breathing, Circulation)
prioritization. While notifying the RN and other interventions are important, initiating
oxygen therapy takes precedence to stabilize the client.
Question 12: When assessing a client for signs of dehydration, which finding should
the practical nurse expect?
A. Bradycardia
B. Increased skin turgor
