N176 FINAL EXAM QUESTIONS WITH DETAILED RATIONALES | 2026–2027
N176 FINAL EXAM
Questions with Detailed Rationales | 2026–2027
100 original A–D practice questions • Correct answers • Detailed rationales • Incorrect-option explanations
Purpose and scope
This resource contains original practice questions for broad adult-health and practical-nursing review. N176 course codes
and final-exam objectives vary by institution. Because no school syllabus was provided, these questions are not a verified
match to a specific course's final exam. Use your syllabus, instructor guidance, assigned materials, and facility protocols to
confirm the examinable scope.
Instructions
• Choose the single best answer for each question before reviewing the rationale.
• For priority questions, consider airway, breathing, circulation, acute change, and immediate safety.
• Read the explanations for incorrect options to strengthen clinical judgment rather than memorizing answer letters.
• These questions are for study and review; they are not official, leaked, or verified school exam questions.
Practice questions and detailed rationales
Question 1. A client with heart failure suddenly develops severe dyspnea, crackles, and pink frothy
sputum. Which action should the nurse take first?
A. Place the client flat and elevate the legs
B. Position the client upright and apply oxygen as prescribed
C. Encourage oral fluids to thin secretions
D. Obtain a daily weight before intervening
Correct answer: B. Position the client upright and apply oxygen as prescribed
Detailed rationale: These findings suggest acute pulmonary edema. Upright positioning reduces venous return and
improves ventilation; oxygen and urgent escalation are indicated while the nurse rapidly assesses the client.
Why A is incorrect: Lying flat can worsen pulmonary congestion and breathing.
Why C is incorrect: Additional fluid can worsen fluid overload.
Why D is incorrect: A daily weight is useful for monitoring heart failure but does not address an acute respiratory
emergency.
Question 2. A client reports crushing chest pressure radiating to the jaw with diaphoresis. What is the
nurse's priority?
A. Arrange a routine outpatient appointment
B. Ask the client to walk to see whether symptoms improve
C. Activate the emergency response pathway and obtain rapid assessment
D. Offer a meal to reduce nausea
Correct answer: C. Activate the emergency response pathway and obtain rapid assessment
Detailed rationale: Possible acute coronary syndrome requires immediate emergency assessment, prompt ECG and
treatment under protocol. Do not delay escalation.

, N176 FINAL EXAM QUESTIONS WITH DETAILED RATIONALES | 2026–2027
Why A is incorrect: Routine follow-up dangerously delays evaluation of a possible myocardial infarction.
Why B is incorrect: Exertion increases cardiac workload and is unsafe during suspected ischemia.
Why D is incorrect: Food is not the priority and may complicate urgent procedures.
Question 3. Which finding is most concerning in a client receiving an opioid after surgery?
A. Pain rated 6/10
B. Respiratory rate 8/min and difficult arousal
C. Mild nausea after medication
D. No bowel movement for one day
Correct answer: B. Respiratory rate 8/min and difficult arousal
Detailed rationale: Bradypnea with reduced responsiveness indicates possible opioid-induced respiratory
depression. Support airway and breathing, summon help, and follow emergency protocol, including naloxone when
indicated.
Why A is incorrect: Pain requires assessment and treatment, but it is not the most immediate threat.
Why C is incorrect: Nausea is a known adverse effect but is less urgent than respiratory depression.
Why D is incorrect: Constipation is common with opioids and is not the immediate priority.
Question 4. A client with diabetes is awake, shaky, and diaphoretic. Point-of-care glucose is 54 mg/dL. The
client can swallow safely. What should the nurse do?
A. Give 15 g of fast-acting carbohydrate and recheck glucose in about 15 minutes
B. Administer the scheduled rapid-acting insulin
C. Give a high-fat meal and recheck in two hours
D. Keep the client NPO until the provider arrives
Correct answer: A. Give 15 g of fast-acting carbohydrate and recheck glucose in about 15 minutes
Detailed rationale: For an alert client able to swallow, treat hypoglycemia with approximately 15 g fast-acting
carbohydrate and recheck in 15 minutes; repeat if still low and then provide follow-up food as appropriate.
Why B is incorrect: Insulin can worsen the hypoglycemia.
Why C is incorrect: Fat slows carbohydrate absorption and waiting two hours delays reassessment.
Why D is incorrect: NPO status is inappropriate when the client can safely take oral carbohydrate.
Question 5. A client with diabetes is confused, unconscious, and has a glucose of 32 mg/dL. No IV access
is available. Which intervention is most appropriate under protocol?
A. Give oral glucose gel by mouth
B. Administer glucagon by an approved route and summon help
C. Wait 30 minutes and repeat the glucose
D. Give the usual mealtime insulin
Correct answer: B. Administer glucagon by an approved route and summon help
Detailed rationale: Severe hypoglycemia with impaired consciousness is an emergency. Do not give anything by
mouth because of aspiration risk; glucagon may be given per protocol while emergency help is obtained.
Why A is incorrect: Oral products are unsafe in an unconscious client due to aspiration risk.
Why C is incorrect: Waiting delays treatment of a life-threatening condition.
Why D is incorrect: Insulin would further lower glucose.

Question 6. A client with COPD is increasingly drowsy and has shallow respirations. What is the nurse's
best initial response?
A. Assume this is the client's normal baseline
B. Assess airway, breathing, oxygenation, and promptly escalate
C. Encourage the client to sleep
D. Withhold all assessment until the next scheduled round
Correct answer: B. Assess airway, breathing, oxygenation, and promptly escalate
Detailed rationale: New drowsiness and shallow breathing may indicate hypoxemia, hypercapnia, or respiratory
failure. Immediate assessment and escalation are required; oxygen should be titrated to the prescribed target while
avoiding delays in treating instability.
Why A is incorrect: A change in mental status is not safely dismissed as baseline.
Why C is incorrect: Sleep does not address possible respiratory failure.
Why D is incorrect: Scheduled rounds must not delay response to deterioration.
Question 7. A client with suspected stroke develops facial droop and unilateral arm weakness 20 minutes
ago. What is the priority nursing action?
A. Give water to assess swallowing
B. Document the findings and wait for the next physician round
C. Activate the stroke response and determine last-known-well time
D. Lower the head of the bed and encourage sleep
Correct answer: C. Activate the stroke response and determine last-known-well time
Detailed rationale: Time-sensitive stroke evaluation may allow reperfusion treatment. Activate the stroke pathway
immediately and establish the last-known-well time; keep the client NPO until swallowing is screened.
Why A is incorrect: Swallowing may be impaired, creating aspiration risk.
Why B is incorrect: Waiting may eliminate time-sensitive treatment options.
Why D is incorrect: This delays evaluation and does not treat the emergency.
Question 8. A client with chronic kidney disease has potassium 6.4 mEq/L and peaked T waves. Which
action is the priority?
A. Encourage a banana for potassium replacement
B. Place the client on cardiac monitoring and urgently notify the provider
C. Recheck the potassium at the next routine lab draw
D. Administer a potassium supplement
Correct answer: B. Place the client on cardiac monitoring and urgently notify the provider
Detailed rationale: Severe hyperkalemia with ECG changes can precipitate fatal dysrhythmias. Continuous
monitoring and immediate escalation are required; emergency therapies may be ordered.
Why A is incorrect: Bananas contain potassium and could worsen hyperkalemia.
Why C is incorrect: Waiting is unsafe with ECG changes.
Why D is incorrect: Potassium supplementation would worsen the abnormality.
Question 9. A client taking furosemide reports weakness and muscle cramps. Potassium is 2.8 mEq/L.
What is the nurse's best action?
A. Recognize possible hypokalemia, assess cardiac status, and notify the provider promptly
B. Recommend avoiding all potassium-containing foods indefinitely
Original educational practice resource • Not an official or verified institutional exam
, N176 FINAL EXAM QUESTIONS WITH DETAILED RATIONALES | 2026–2027
C. Give an extra dose of furosemide
D. Document the finding as expected and take no action
Correct answer: A. Recognize possible hypokalemia, assess cardiac status, and notify the provider promptly
Detailed rationale: Loop diuretics can cause potassium loss. Significant hypokalemia increases dysrhythmia risk and
needs prompt assessment, provider notification, and replacement orders as appropriate.
Why B is incorrect: Diet advice must be individualized; blanket restriction may worsen deficiency.
Why C is incorrect: An extra loop diuretic dose can worsen potassium loss.
Why D is incorrect: A potassium of 2.8 mEq/L is clinically significant and should not be ignored.
Question 10. A postoperative client has unilateral calf swelling, warmth, and pain. What should the nurse
do?
A. Massage the calf to relieve discomfort
B. Encourage vigorous walking immediately
C. Notify the provider and assess for possible venous thromboembolism
D. Apply a tight bandage and ignore the symptoms
Correct answer: C. Notify the provider and assess for possible venous thromboembolism
Detailed rationale: Unilateral swelling, warmth, and pain may indicate deep-vein thrombosis. Prompt assessment
and escalation are needed; avoid massaging the limb.
Why A is incorrect: Massage may dislodge a thrombus and is not appropriate.
Why B is incorrect: Activity should follow clinical assessment and orders when DVT is suspected.
Why D is incorrect: Compression decisions require assessment and an appropriate plan; ignoring symptoms is unsafe.
Question 11. A client suddenly develops pleuritic chest pain, tachycardia, and severe shortness of breath
after surgery. What complication should the nurse suspect?
A. Constipation
B. Pulmonary embolism
C. Expected postoperative fatigue
D. Uncomplicated incisional pain
Correct answer: B. Pulmonary embolism
Detailed rationale: Sudden dyspnea, pleuritic pain, and tachycardia after surgery are concerning for pulmonary
embolism. Activate urgent evaluation and support oxygenation.
Why A is incorrect: Constipation does not explain acute respiratory distress.
Why C is incorrect: These are red flags, not routine fatigue.
Why D is incorrect: Incisional pain does not adequately explain sudden severe dyspnea.
Question 12. A client receiving a blood transfusion develops chills, back pain, and fever. What should the
nurse do first?
A. Slow the transfusion and continue observing
B. Stop the transfusion and maintain IV access with normal saline using new tubing per protocol
C. Discard the blood bag without notifying anyone
D. Give the next unit to finish the prescribed dose
Correct answer: B. Stop the transfusion and maintain IV access with normal saline using new tubing per protocol
