Verified – Pass Guaranteed – A+ Graded
SECTION A: TRADITIONAL MULTIPLE CHOICE (Questions 1–35)
1. A 78-year-old client with heart failure is prescribed furosemide 40 mg PO daily. The
LPN should monitor for which adverse effect?
A) Hyperkalemia
B) Hypokalemia
C) Hypernatremia
D) Bradycardia
Correct Answer: B
Rationale: Furosemide is a loop diuretic that causes potassium wasting through the
kidneys, leading to hypokalemia. The LPN must monitor potassium levels and report
hypokalemia to the RN or provider. Option A is incorrect because furosemide causes
potassium loss, not retention. Option C is incorrect because furosemide causes sodium
loss, not retention. Option D is incorrect because furosemide does not typically cause
bradycardia.
2. The LPN is caring for a client with a stage 2 pressure injury on the coccyx. Which
action is within the LPN scope of practice?
,A) Prescribing a hydrocolloid dressing
B) Assessing the wound and documenting findings for the RN
C) Developing a comprehensive wound care plan independently
D) Ordering wound culture and sensitivity testing
Correct Answer: B
Rationale: LPNs may assess wounds and document findings under RN supervision;
comprehensive wound care plan development (C) and ordering diagnostics (D) are
RN/provider functions. Option A is incorrect because prescribing dressings is outside
LPN scope.
3. A client with type 2 diabetes has a fasting blood glucose of 248 mg/dL. The LPN
should:
A) Administer the prescribed sliding scale insulin and notify the RN
B) Withhold breakfast and recheck in 2 hours
C) Give the client orange juice to prevent hypoglycemia
D) Document the finding and take no further action
Correct Answer: A
Rationale: Elevated fasting glucose requires intervention per protocol; the LPN
administers prescribed sliding scale insulin and reports to the RN for ongoing
assessment. Option B risks further hyperglycemia. Option C is contraindicated with
hyperglycemia. Option D is negligent.
,4. A postoperative client has a Jackson-Pratt drain with 45 mL of serosanguineous
drainage in 8 hours. The LPN should:
A) Notify the surgeon immediately
B) Empty, measure, and record the drainage per protocol
C) Remove the drain because output is decreasing
D) Milk the drain tubing forcefully every hour
Correct Answer: B
Rationale: 45 mL of serosanguineous drainage in 8 hours is expected postoperatively;
the LPN empties, measures, and records per protocol. Option A is unnecessary for
expected drainage. Option C exceeds LPN scope. Option D risks tissue trauma.
5. A client receiving enteral feeding via nasogastric tube develops abdominal distension
and residual of 350 mL. The LPN should:
A) Continue the feeding at the current rate
B) Hold the feeding and notify the RN
C) Flush the tube with 100 mL of water
D) Reposition the client and recheck in 30 minutes
Correct Answer: B
Rationale: Gastric residual volume exceeding 250–500 mL (per facility protocol)
indicates delayed gastric emptying; the LPN holds the feeding and reports to the RN for
, provider notification. Option A risks aspiration. Option C does not address the
underlying issue. Option D delays necessary intervention.
6. The LPN is preparing to administer digoxin 0.125 mg PO to a client with atrial
fibrillation. Before administration, the LPN should:
A) Assess the apical pulse for 1 full minute
B) Check the blood pressure in both arms
C) Measure the respiratory rate for 30 seconds
D) Obtain a capillary blood glucose level
Correct Answer: A
Rationale: Digoxin is contraindicated if the apical pulse is below 60 bpm in adults; the
LPN must assess for 1 full minute before administration. Options B, C, and D are not
specific digoxin safety checks.
7. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2
L/min via nasal cannula. The LPN notes the client is somnolent with a respiratory rate of
8/min. The priority action is:
A) Increase the oxygen flow to 6 L/min
B) Stimulate the client and notify the RN immediately
C) Administer a prescribed PRN sedative
D) Place the client in high Fowler's position
Correct Answer: B
