(PN/LPN) Verified Questions and Answers
Elaborate Rationales
GRADE A+
1. A practical nurse is preparing to administer oral medications to a client who has a
history of dysphagia following a recent cerebrovascular accident. The client is alert and
oriented but coughs occasionally when drinking thin liquids. The nurse understands
that aspiration is a serious risk in this population. What is the most appropriate initial
nursing action before administering the medication?
A. Crush all medications and mix with water
B. Administer medications with a full glass of water
C. Assess the client’s swallowing ability
D. Request the provider change all medications to IV form
Rationale:
The priority action is to assess the client’s swallowing ability before administering oral
medications. Dysphagia significantly increases the risk of aspiration, which can lead to
aspiration pneumonia, airway obstruction, and decreased oxygenation. The nursing process
requires assessment before implementation, making evaluation of gag reflex, ability to
handle secretions, and tolerance of thickened liquids essential. Crushing medications without
assessment may be unsafe because some medications cannot be crushed. Changing to IV
form requires provider prescription and is not the first nursing action. Safety and airway
protection are the priority.
2. A practical nurse is caring for a client who has a stage II pressure injury on the
sacral area. The client has limited mobility, urinary incontinence, and poor nutritional
intake. The nurse is planning interventions to prevent further skin breakdown and
promote healing. Which intervention should be prioritized?
A. Apply a heating pad to improve circulation
B. Reposition the client at least every 2 hours
C. Massage the reddened areas to increase blood flow
D. Clean the wound once per week
Rationale:
Frequent repositioning at least every two hours is the most important intervention to relieve
,pressure and restore adequate tissue perfusion. Pressure injuries develop due to prolonged
compression of capillaries, resulting in ischemia and tissue damage. Without pressure relief,
healing cannot occur regardless of other treatments. Applying heat may increase tissue
damage, and massaging reddened areas can further injure fragile capillaries. Wound
cleansing should occur more frequently than once weekly. Pressure redistribution remains
the primary preventive and therapeutic measure.
3. A practical nurse is reinforcing medication teaching for a client prescribed
furosemide for management of heart failure. The client states, “I take it at bedtime so I
won’t forget.” The nurse recognizes potential complications related to this schedule.
What is the most appropriate response?
A. “That is fine as long as you limit fluids.”
B. “It is better to take this medication in the morning.”
C. “You should skip the dose if you urinate too much.”
D. “You can double the dose if swelling increases.”
Rationale:
Furosemide is a loop diuretic that increases urine output and can cause significant diuresis
shortly after administration. Taking it at bedtime increases the risk of nocturia, sleep
disruption, and falls—especially in older adults who may rush to the bathroom during the
night. Morning administration reduces fall risk and improves adherence. Skipping or
doubling doses can cause dangerous electrolyte imbalances such as hypokalemia. Proper
timing enhances safety and therapeutic effectiveness.
4. A practical nurse is caring for a postoperative client who suddenly reports sharp
chest pain, shortness of breath, and feelings of impending doom. The client’s oxygen
saturation drops to 88% on room air. The nurse suspects a pulmonary embolism. What
is the priority action?
A. Document findings in the client’s chart
B. Administer prescribed analgesics
C. Apply oxygen and notify the RN or provider immediately
D. Encourage the client to use the incentive spirometer
Rationale:
The client’s symptoms are consistent with a pulmonary embolism, a life-threatening
emergency. According to ABC priority principles, the nurse must address airway and
breathing first. Applying oxygen helps improve oxygenation and prevent hypoxia while rapid
notification ensures prompt medical intervention such as anticoagulation or diagnostic
,imaging. Documentation is important but not the priority during acute deterioration.
Analgesics do not treat the underlying cause. Immediate action can prevent respiratory and
cardiovascular collapse.
5. A practical nurse is performing hand hygiene after caring for multiple clients in a
long-term care facility. One client has a confirmed Clostridium difficile infection. The
nurse understands that certain pathogens require special infection control measures. In
which situation must the nurse use soap and water instead of alcohol-based hand
sanitizer?
A. Before administering oral medications
B. After removing clean gloves
C. After caring for a client with Clostridium difficile
D. Before assisting with feeding
Rationale:
Clostridium difficile produces spores that are resistant to alcohol-based hand sanitizers. The
only effective method for removing these spores is mechanical washing with soap and water.
Alcohol does not destroy spores and may contribute to continued transmission within
healthcare settings. Proper hand hygiene is essential to prevent outbreaks, particularly in
long-term care facilities where clients are at high risk. Using soap and water after contact
with C. difficile significantly reduces infection spread.
6. A practical nurse is caring for an older adult client who is on bed rest following hip
surgery. The client reports calf pain and the nurse notes warmth and redness in the
lower leg. The nurse understands that immobility increases the risk for venous
thromboembolism. What is the priority nursing action?
A. Massage the affected calf
B. Encourage the client to ambulate immediately
C. Report findings to the RN or provider immediately
D. Apply a heating pad to the leg
Rationale:
The client’s symptoms suggest a possible deep vein thrombosis (DVT), which is a serious
condition that can lead to pulmonary embolism if the clot dislodges. Massaging the calf or
encouraging ambulation could dislodge the clot and cause life-threatening complications.
Applying heat is not appropriate until diagnosis is confirmed. The nurse must immediately
report findings so diagnostic testing and anticoagulant therapy can be initiated. Early
recognition and prompt intervention reduce mortality risk.
, 7. A practical nurse is reinforcing teaching to a client newly diagnosed with type 2
diabetes mellitus. The client asks why daily foot inspection is necessary. Which
response by the nurse is most appropriate?
A. “It helps your feet stay clean.”
B. “Diabetes can decrease sensation and delay wound healing.”
C. “You will avoid needing to trim your toenails.”
D. “It prevents swelling in your ankles.”
Rationale:
Clients with diabetes often develop peripheral neuropathy, which reduces sensation in the
feet. They may not feel cuts, blisters, or injuries. Additionally, hyperglycemia impairs
circulation and immune function, delaying wound healing and increasing infection risk.
Daily foot inspection allows early detection of injury and prevents serious complications
such as ulcers or amputation. Education on prevention is a core component of fundamental
nursing care.
8. A practical nurse is preparing to insert an indwelling urinary catheter for a female
client. The nurse understands that catheter-associated urinary tract infections are a
major healthcare concern. Which action is most important to prevent infection during
insertion?
A. Inflate the balloon before insertion
B. Maintain sterile technique throughout the procedure
C. Use clean gloves instead of sterile gloves
D. Lubricate the catheter with normal saline
Rationale:
Maintaining sterile technique is essential during urinary catheter insertion to prevent
introduction of pathogens into the bladder. The urinary tract is normally sterile, and
contamination during insertion is a primary cause of catheter-associated urinary tract
infections (CAUTIs). Inflating the balloon before proper placement can injure the urethra.
Clean gloves are insufficient for sterile procedures. Strict adherence to aseptic technique
protects the client from preventable infection.
9. A practical nurse is caring for a client receiving oxygen via nasal cannula at 2 L/min.
The client reports nasal dryness and irritation. Which intervention is most
appropriate?
