Detailed Rationales | 100% Correct | Grade A+
1. A charge nurse is assigning client care. Which client should be assigned to an experienced LPN/LVN?
A) A client with unstable atrial fibrillation on a continuous heparin drip
B) A client newly diagnosed with diabetic ketoacidosis receiving an insulin infusion
C) A client with a stable tracheostomy requiring routine suctioning every 4 hours
D) A client who is 1-hour post-cardiac catheterization with a femoral sheath in place
Correct Answer: C
Rationale: LPNs/LVNs can perform stable, routine procedures like tracheostomy suctioning. Unstable
rhythms, insulin infusions, and post-procedural sheath management require RN assessment and critical
thinking.
2. The nurse is preparing to administer a blood transfusion. Which client requires the most immediate
intervention before starting the transfusion?
A) A client with a temperature of 37.5°C (99.5°F)
B) A client who reports mild itching but no rash
C) A client with a blood pressure of 90/60 mmHg and heart rate 110 bpm
D) A client who received acetaminophen 30 minutes ago
Correct Answer: C
Rationale: Hypotension and tachycardia suggest hypovolemia or possible active bleeding; transfusion
could worsen fluid overload if heart failure is present, but these vitals need immediate provider
notification. Mild itching or low-grade fever is less urgent.
3. A nurse in the emergency department is triaging four clients. Which client should the nurse see first?
A) A client with a simple fracture of the radius requesting pain medication
B) A client with a history of COPD and oxygen saturation of 89% on 2 L nasal cannula
C) A client with a urinary tract infection and a temperature of 38.3°C (101°F)
D) A client with a headache and blood pressure of 190/110 mmHg who is asymptomatic
,Correct Answer: B
Rationale: Hypoxemia despite supplemental oxygen indicates respiratory compromise. The COPD client
is at risk for acute exacerbation and requires immediate assessment. The asymptomatic hypertensive
client can wait briefly.
4. A nurse is caring for a client with a chest tube after a thoracotomy. The drainage system is
disconnected from the chest tube. What is the priority action?
A) Clamp the chest tube near the insertion site
B) Place the end of the chest tube in a bottle of sterile water
C) Notify the respiratory therapist
D) Apply an occlusive dressing over the insertion site
Correct Answer: B
Rationale: Placing the open end of the chest tube in sterile water creates a water seal and prevents air
from entering the pleural space while maintaining drainage. Clamping can cause tension pneumothorax;
an occlusive dressing is for accidental dislodgement.
5. A client with heart failure is receiving furosemide (Lasix) IV push. Which assessment finding requires
immediate action?
A) Urine output of 200 mL in the past 2 hours
B) Serum potassium of 3.2 mEq/L
C) Blood pressure of 110/70 mmHg
D) Complaints of tinnitus
Correct Answer: D
Rationale: Tinnitus can indicate ototoxicity from rapid furosemide administration. The nurse should slow
the infusion rate and notify the provider. Hypokalemia (3.2) is a concern but not emergent; urine output
is adequate.
6. A nurse is teaching a client with newly diagnosed type 1 diabetes about insulin administration. Which
statement indicates correct understanding?
A) "I will store my unopened insulin vials in the freezer to keep them fresh."
B) "I will inject insulin into the same spot each time to ensure consistency."
C) "I will rotate injection sites within the same anatomical region."
,D) "I will massage the injection site after administration to improve absorption."
Correct Answer: C
Rationale: Rotating within the same region (e.g., abdomen) prevents lipohypertrophy and erratic
absorption. Unopened insulin is refrigerated (not frozen); rotation prevents lipodystrophy; massage is
not recommended.
7. A client with preeclampsia is receiving magnesium sulfate IV. The nurse notes a respiratory rate of 10
breaths per minute. What is the priority action?
A) Administer oxygen via face mask
B) Stop the magnesium sulfate infusion
C) Notify the healthcare provider
D) Prepare for intubation
Correct Answer: B
Rationale: Respiratory depression (<12 breaths/min) is a sign of magnesium toxicity. The infusion must
be stopped immediately. After stopping, notify the provider and administer calcium gluconate if
ordered.
8. The nurse is assessing a client who has a new diagnosis of deep vein thrombosis (DVT) in the left calf.
Which finding is most concerning?
A) Left calf circumference 2 cm larger than the right
B) Pain upon dorsiflexion of the left foot
C) Sudden onset of shortness of breath and chest pain
D) Warmth and erythema over the left calf
Correct Answer: C
Rationale: Sudden dyspnea and chest pain suggest pulmonary embolism (PE), a life-threatening
complication of DVT. The nurse should administer oxygen and notify the provider immediately. The
other findings are expected with DVT.
9. A client is receiving chemotherapy and has a platelet count of 25,000/mm³. Which precaution is most
important?
A) Neutropenic precautions
B) Bleeding precautions
, C) Contact precautions
D) Airborne precautions
Correct Answer: B
Rationale: Severe thrombocytopenia (platelets <50,000) places the client at high risk for bleeding.
Bleeding precautions include using soft toothbrushes, avoiding IM injections, preventing falls, and
applying pressure to puncture sites. Neutropenic precautions are for low WBC.
10. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which medication should
the nurse withhold on the morning of dialysis?
A) Furosemide (Lasix)
B) Epoetin alfa (Epogen)
C) Lisinopril
D) Calcium acetate (PhosLo)
Correct Answer: D
Rationale: Phosphate binders (calcium acetate) are given with meals, not withheld; however, some
antihypertensives and diuretics are held before dialysis to prevent hypotension. Actually, diuretics
(furosemide) are often held because dialysis removes fluid. The better answer: furosemide should be
withheld because the client will not produce urine during dialysis and it may cause hypotension. But
PhosLo is taken with meals. The most common medication held on dialysis day is antihypertensives to
avoid intradialytic hypotension. Let's clarify: Furosemide is often held because kidneys are
nonfunctional; the nurse should check provider orders. Standard NCLEX: hold antihypertensives and
diuretics on dialysis day. Correct answer: A (Furosemide).
11. A client is admitted with acute pancreatitis. Which laboratory finding is most consistent with this
diagnosis?
A) Decreased serum amylase
B) Elevated serum lipase
C) Decreased white blood cell count
D) Elevated blood urea nitrogen (BUN)
Correct Answer: B
Rationale: Lipase is the most specific marker for acute pancreatitis; it remains elevated longer than
amylase. Amylase is also elevated early. WBC may be elevated due to inflammation. BUN may rise from
dehydration but is not diagnostic.
