Review
Question 1: A patient with a history of chronic obstructive pulmonary disease
(COPD) is receiving oxygen at 2 L/min via nasal cannula. The patient’s spouse
calls the nurse and reports that the patient is lethargic and difficult to arouse.
What is the nurse's priority action?
A. Increase the oxygen flow rate to 4 L/min.
B. Assess the patient’s respiratory rate and depth.
C. Place the patient in a supine position.
D. Prepare for immediate intubation.
CORRECT ANSWER: B. Assess the patient’s respiratory rate and depth.
Rationale: In a patient with COPD, lethargy may indicate carbon dioxide (CO2) narcosis
due to hypoventilation. The nurse’s priority is to assess the respiratory status, including
rate, depth, and rhythm, to evaluate for respiratory depression. Increasing oxygen
without assessment could worsen hypoventilation. A supine position would further
compromise breathing, and intubation is not the immediate first action without further
assessment.
Question 2: A newly hired LVN is reviewing the scope of practice for vocational
nursing in California. According to the California Board of Vocational Nursing
and Psychiatric Technicians (BVNPT), which task is within the LVN’s scope of
practice?
A. Initiating a plan of care independently for a complex patient.
B. Administering intravenous push (IVP) medications without certification.
C. Performing a focused assessment and reporting findings to the RN.
D. Interpreting arterial blood gas results to adjust ventilator settings.
CORRECT ANSWER: C. Performing a focused assessment and reporting
findings to the RN.
Rationale: In California, LVNs perform focused assessments and report significant
findings to the RN or provider. They do not initiate care plans independently for
complex patients (this is the RN's role), administer IVP medications without specific
certification, or interpret ABGs to adjust ventilators, which is outside the LVN scope.
,Question 3: A patient is prescribed furosemide (Lasix) 40 mg IV push. Prior to
administration, the LVN notes that the patient's potassium level is 2.9 mEq/L.
What is the most appropriate action?
A. Administer the medication as ordered.
B. Hold the medication and notify the healthcare provider.
C. Administer the medication with a potassium supplement.
D. Increase the patient's oral fluid intake.
CORRECT ANSWER: B. Hold the medication and notify the healthcare
provider.
Rationale: Furosemide is a loop diuretic that depletes potassium. The patient has
hypokalemia (normal range: 3.5–5.0 mEq/L). Administering furosemide could further
lower potassium levels, increasing the risk of cardiac arrhythmias. The nurse should
hold the medication and notify the provider for further orders.
Question 4: In Texas, the LVN is caring for a patient who requires a sterile
dressing change. Which action demonstrates proper sterile technique?
A. Opening the sterile package away from the body and placing it on a clean, dry
surface.
B. Using sterile gloves to clean the wound and then applying the dressing with the same
gloves.
C. Setting up the sterile field, then placing the sterile items within 1 inch of the field's
edge.
D. Donning sterile gloves before opening the sterile dressing package.
CORRECT ANSWER: A. Opening the sterile package away from the body and
placing it on a clean, dry surface.
Rationale: Proper sterile technique involves opening the outer flap of a sterile package
away from the body to prevent contamination. The sterile field is placed on a clean, dry
surface. The 1-inch border is considered contaminated; sterile items should not be
placed there. Sterile gloves should be donned after opening the package, and the same
gloves used for cleaning and applying the dressing would cause contamination.
Question 5: A patient reports a dull, aching pain in the right lower quadrant of
the abdomen, accompanied by nausea and anorexia. The LVN notes a
temperature of 100.8°F. Which condition should the nurse suspect?
A. Gastroenteritis
B. Peptic ulcer disease
C. Cholecystitis
D. Appendicitis
,CORRECT ANSWER: D. Appendicitis.
Rationale: Appendicitis typically presents with periumbilical pain that migrates to the
right lower quadrant (McBurney's point), nausea, anorexia, and low-grade fever.
Gastroenteritis usually involves diffuse abdominal pain and diarrhea. Peptic ulcer
disease presents with epigastric pain, and cholecystitis presents with right upper
quadrant pain.
Question 6: The LVN is providing discharge teaching to a patient with a new
colostomy. Which statement by the patient indicates a correct understanding
of dietary management?
A. "I should avoid all high-fiber foods to prevent blockage."
B. "I can eat popcorn and nuts as long as I chew them well."
C. "I need to increase my fluid intake to prevent dehydration."
D. "I should only eat foods that are pureed for the first month."
CORRECT ANSWER: C. "I need to increase my fluid intake to prevent
dehydration."
Rationale: Patients with a colostomy are at risk for dehydration, especially if output is
high. Increasing fluid intake is essential. Foods like popcorn and nuts are high in fiber
and can cause blockage. Not all high-fiber foods need to be avoided permanently; they
should be introduced cautiously. Pureed foods are not required for all colostomy
patients.
Question 7: A patient with type 1 diabetes mellitus is experiencing
diaphoresis, tremors, and confusion. The LVN checks the patient’s blood
glucose and it is 52 mg/dL. What is the priority nursing intervention?
A. Administer 10 units of regular insulin.
B. Give the patient 4 ounces of orange juice.
C. Notify the physician immediately.
D. Provide a high-protein snack.
CORRECT ANSWER: B. Give the patient 4 ounces of orange juice.
Rationale: The patient is exhibiting signs of hypoglycemia (blood glucose < 70 mg/dL).
The immediate treatment is to provide a fast-acting carbohydrate such as 4–6 ounces of
fruit juice or regular soda. Insulin would further lower glucose. A high-protein snack is
not fast-acting enough for acute hypoglycemia.
Question 8: The LVN is assessing an elderly patient who reports difficulty
swallowing and a sensation of food getting stuck in the throat. The nurse
should instruct the patient to:
, A. Lie flat immediately after meals to promote digestion.
B. Take small bites and eat slowly while sitting upright.
C. Drink thick liquids such as milkshakes to ease swallowing.
D. Avoid all solid foods and rely on a liquid diet.
CORRECT ANSWER: B. Take small bites and eat slowly while sitting upright.
Rationale: For patients with dysphagia, sitting upright and taking small, manageable
bites reduces the risk of aspiration. Lying flat increases aspiration risk. Thickened liquids
are sometimes recommended, but milkshakes are not appropriate for all patients.
Avoiding all solids is not the first recommendation without further assessment.
Question 9: The LVN is caring for a patient receiving a blood transfusion.
Fifteen minutes after initiation, the patient reports chills and low back pain.
What is the nurse’s priority action?
A. Slow the infusion rate and continue monitoring.
B. Stop the transfusion and keep the IV line open with normal saline.
C. Administer diphenhydramine (Benadryl) as ordered.
D. Document the findings and notify the physician.
CORRECT ANSWER: B. Stop the transfusion and keep the IV line open with
normal saline.
Rationale: The patient is exhibiting signs of a possible transfusion reaction (chills, back
pain). The immediate priority is to stop the transfusion and maintain IV access with
normal saline to prevent further reaction and prepare for emergency interventions.
Notifying the provider and documenting are important but secondary to stopping the
infusion.
Question 10: A patient is diagnosed with a urinary tract infection (UTI) and
prescribed ciprofloxacin. The LVN provides patient education regarding this
medication. Which statement by the patient indicates a need for further
teaching?
A. "I will take this medication with a full glass of water."
B. "I should avoid taking this medication with dairy products."
C. "I will stop taking the medication once I feel better."
D. "I will report any tendon pain to my doctor."
CORRECT ANSWER: C. "I will stop taking the medication once I feel better."
Rationale: Antibiotics should be taken for the full prescribed course to prevent
recurrence and antibiotic resistance. Ciprofloxacin should be taken with plenty of water,
avoided with dairy due to decreased absorption, and tendon pain should be reported as
it can indicate tendon rupture.
