QUESTIONS & VERIFIED ANSWERS | ULTIMATE NCLEX REVIEW
DOCUMENT OVERVIEW
• This comprehensive practice exam contains verified NCLEX-RN style questions
covering all major nursing domains—use these questions to assess readiness,
identify weak areas, and build confidence through repeated study sessions
• Focus on understanding the rationale behind each answer rather than
memorizing; apply critical thinking to each scenario and review incorrect answers
multiple times to reinforce learning and clinical decision-making skills
QUESTIONS
Question 1
A nurse is caring for a client with congestive heart failure who reports shortness of
breath. Which of the following positions would be MOST appropriate for this client?
A) Supine with head flat
B) Semi-Fowler's position
C) High Fowler's position with feet elevated
D) Prone position
E) Trendelenburg position
CORRECT ANSWER: C) High Fowler's position with feet elevated
Rationale: High Fowler's position (45-90 degrees) promotes optimal lung
expansion and allows gravity to assist with venous return to the heart, reducing
pulmonary congestion and dyspnea. Elevating the feet helps reduce peripheral
,edema and fluid accumulation in the lungs. Supine positioning would worsen
breathing difficulties. Trendelenburg would increase fluid in the lungs. This is
standard positioning for respiratory distress in heart failure.
Question 2
A 45-year-old male client admitted to the cardiac unit is on heparin therapy. Which
of the following laboratory values would indicate therapeutic anticoagulation?
A) Prothrombin time (PT) of 12 seconds
B) Activated partial thromboplastin time (aPTT) of 60 seconds
C) International normalized ratio (INR) of 1.5
D) Platelet count of 150,000/mm³
E) Hemoglobin of 10 g/dL
CORRECT ANSWER: B) Activated partial thromboplastin time (aPTT) of 60
seconds
Rationale: Heparin therapy is monitored by aPTT levels. Therapeutic range for
aPTT is typically 1.5-2.5 times the control value, usually 60-85 seconds depending
on the laboratory. PT and INR are used to monitor warfarin (Coumadin), not
heparin. Platelet count and hemoglobin are not direct measures of anticoagulation
effectiveness. aPTT is the gold standard for assessing heparin efficacy.
Question 3
A nurse is assessing a client with acute myocardial infarction (AMI). Which of the
following findings would be MOST indicative of cardiogenic shock?
A) Blood pressure 140/90 mmHg with heart rate of 72 bpm
B) Systolic blood pressure less than 90 mmHg with cool, clammy skin
C) Hypertension with bradycardia
D) Normal blood pressure with tachypnea
,E) Hypotension with warm, flushed skin
CORRECT ANSWER: B) Systolic blood pressure less than 90 mmHg with cool,
clammy skin
Rationale: Cardiogenic shock occurs when the heart cannot pump blood
effectively. Classic signs include hypotension (SBP <90 mmHg), tachycardia,
cool/clammy skin due to peripheral vasoconstriction and decreased perfusion,
altered mental status, and reduced urine output. The cool, clammy skin indicates
severe hypoperfusion and sympathetic nervous system activation. This is a life-
threatening emergency requiring immediate intervention.
Question 4
A client receiving IV morphine for severe pain is found to be unresponsive with a
respiratory rate of 6 breaths per minute. Which medication should the nurse
prepare to administer immediately?
A) Atropine sulfate
B) Naloxone (Narcan)
C) Diazepam (Valium)
D) Flumazenil (Romazicon)
E) Metoclopramide (Reglan)
CORRECT ANSWER: B) Naloxone (Narcan)
Rationale: The client exhibits opioid overdose/toxicity with respiratory depression
(rate of 6 is dangerously low; normal is 12-20). Naloxone is a competitive opioid
antagonist that reverses the effects of opioids, including respiratory depression. It
should be administered IV and acts within 2-5 minutes. Atropine treats
anticholinergic toxicity. Diazepam is a benzodiazepine (has its own antagonist,
flumazenil). Metoclopramide is an antiemetic. Naloxone is the life-saving
intervention here.
, Question 5
A nurse caring for a postoperative client notes the following: temperature 38.5°C
(101.3°F), heart rate 110 bpm, blood pressure 95/60 mmHg, respiratory rate 24
breaths/min, and the client appears confused. Which complication should the nurse
suspect?
A) Hypovolemic shock
B) Septic shock
C) Neurogenic shock
D) Anaphylactic shock
E) Cardiogenic shock
CORRECT ANSWER: B) Septic shock
Rationale: Septic shock presents with fever, tachycardia, tachypnea, hypotension,
and altered mental status—all evident in this postoperative client. Infection (often
from surgical wound or line contamination) triggers systemic inflammatory
response, causing vasodilation and distributive shock. While hypovolemic shock can
occur postoperatively, it typically presents with cool skin; septic shock patients are
often warm/flushed initially. Neurogenic and anaphylactic shocks have different
presentations. Early recognition and antibiotics/fluid resuscitation are critical.
Question 6
A client with chronic kidney disease has a serum potassium level of 6.5 mEq/L.
Which of the following interventions should the nurse implement FIRST?
A) Restrict dietary potassium intake
B) Administer sodium polystyrene sulfonate (Kayexalate)
C) Obtain a 12-lead ECG
D) Start the client on dialysis
E) Administer potassium supplements
