LPN/LVN Module Exam 3 (Week 9) Practice Quiz 2026 UPDATE |SBON
1. A nurse is caring for a patient receiving furosemide. Which electrolyte
imbalance should the nurse monitor for most closely?
A. Hyperkalemia
B. Hypernatremia
C. Hypokalemia
D. Hypocalcemia
Answer: C
Rationale: Furosemide is a loop diuretic that causes the excretion of potassium along with
water and sodium, frequently leading to hypokalemia.
2. Which of the following is the most appropriate site for an intramuscular
injection in an infant under 12 months of age?
A. Deltoid
B. Dorsogluteal
C. Ventrogluteal
D. Vastus lateralis
Answer: D
Rationale: The vastus lateralis is the preferred site for IM injections in infants because it is
the most developed muscle at that age.
,3. A patient is diagnosed with Type 1 Diabetes Mellitus. Which symptom is most
indicative of hypoglycemia?
A. Extreme thirst
B. Frequent urination
C. Fruity-smelling breath
D. Diaphoresis and shakiness
Answer: D
Rationale: Diaphoresis (sweating) and shakiness are common early signs of hypoglycemia;
thirst and fruity breath are associated with hyperglycemia/DKA.
4. When assessing a patient with a suspected deep vein thrombosis (DVT),
which finding is most common?
A. Bilateral leg edema
B. Coolness of the affected limb
C. Unilateral calf pain and swelling
D. Absent pedal pulses
Answer: C
Rationale: DVT typically presents with unilateral (one-sided) symptoms including pain,
warmth, and swelling in the affected leg.
5. Which position is most appropriate for a patient immediately following a liver
biopsy?
A. High-Fowler’s
B. Left lateral recumbent
C. Right lateral recumbent
D. Supine with head of bed flat
Answer: C
Rationale: Positioning the patient on the right side applies pressure to the biopsy site,
which helps prevent hemorrhage.
, 6. A nurse is preparing to administer digoxin. Which vital sign must be checked
prior to administration?
A. Apical pulse
B. Respiratory rate
C. Blood pressure
D. Temperature
Answer: A
Rationale: The apical pulse must be checked for one full minute; the dose is typically held
if the heart rate is below 60 bpm in adults.
7. What is the primary purpose of pursed-lip breathing in patients with COPD?
A. To strengthen the diaphragm
B. To decrease the respiratory rate
C. To increase the inhaled oxygen concentration
D. To promote carbon dioxide elimination
Answer: D
Rationale: Pursed-lip breathing keeps the airways open longer during exhalation,
facilitating the removal of trapped CO2.
8. An elderly patient is at risk for falls. Which intervention is the most effective
safety measure?
A. Applying bilateral soft wrist restraints
B. Ensuring the call bell is within reach
C. Keeping all four side rails up
D. Administering a mild sedative at bedtime
Answer: B
Rationale: Accessibility to the call bell allows the patient to ask for help; restraints and full
side rails can actually increase injury risk.
