N176 Comprehensive Exam Review
2026–2027 | High-yield nursing concepts, clinical priorities, and practice questions
COURSE-SCOPE NOTE: N176 may cover different material across schools and nursing
programs. This guide reviews broad adult-health and practical-nursing concepts; it is not verified
against a particular institution's syllabus and is not an official, leaked, or actual course
examination.
How to use this review
• Review the priority principles first, then study each system section and its red flags.
• Answer the practice questions without looking at the key. For every missed item, explain why
the correct answer is safest.
• Use your current syllabus, instructor guidance, assigned textbook, medication references,
and facility protocols to resolve course-specific differences.
• Practice prioritization: identify immediate threats, act within scope, notify the appropriate
clinician, and reassess the response.
1. Clinical judgment and prioritization
Use a structured sequence: recognize cues, analyze the data, identify the most likely/most
dangerous problem, plan safe actions, implement, and evaluate the response. Prioritize actual
instability over routine needs.

needed.
2. Respiratory and oxygenation
• Assess respiratory rate and pattern, work of breathing, speech, mental status, skin color,
breath sounds, and oxygen saturation in context.
• Urgent warning signs include stridor, cyanosis, silent chest during severe asthma, inability to
speak, declining consciousness, and rapidly worsening oxygenation.
• Pneumonia: monitor oxygenation, fever, work of breathing, hydration, mobility, and response
to treatment.
• COPD: use the prescribed oxygen target and orders; do not withhold needed oxygen or
independently adjust beyond protocol. New drowsiness may indicate hypercapnia or
deterioration.
• Asthma: severe effort with reduced air movement can be more dangerous than loud
wheezing. Follow the prescribed rescue plan and escalate when symptoms are severe.
• Aspiration prevention: stop feeding if choking/coughing occurs, assess airway and breathing,
and follow swallowing-screen and diet orders.
• Tuberculosis: suspected infectious pulmonary TB generally requires airborne precautions
and appropriate respiratory protection per policy.
3. Cardiovascular and perfusion
• Possible acute coronary syndrome: chest pressure, diaphoresis, nausea, dyspnea, or
unexplained weakness warrants rapid assessment and emergency pathway activation.

• Heart failure: track daily weight, edema, lung sounds, orthopnea, intake/output,
oxygenation, and trends. Rapid weight gain with worsening dyspnea needs prompt reporting.
• Peripheral arterial disease often causes coolness, diminished pulses, and exertional pain
relieved by rest; venous insufficiency often causes dependent edema and brown ankle
discoloration.
• DVT warning signs include new unilateral swelling, warmth, and pain. Do not massage a
potentially thrombosed leg; obtain prompt evaluation.
• Anticoagulants: report black tarry stool, vomiting blood, unexplained bruising, severe
headache after trauma, or other significant bleeding.
• Orthostatic assessment compares measurements across positions and includes symptoms;
assist the client during position changes.
4. Endocrine and glucose regulation
• Hypoglycemia may cause sweating, tremor, hunger, confusion, or behavior change. If alert
and able to swallow, give rapid-acting carbohydrate per protocol and recheck. If
unconscious, do not give oral food or liquid; use emergency protocol.
• DKA warning signs include dehydration, nausea/vomiting, abdominal pain, fruity breath, and
deep rapid respirations. Escalate promptly.
• NPO status requires an individualized diabetes medication and glucose-monitoring plan; do
not give meal insulin without accounting for food intake.
• Levothyroxine is generally taken consistently on an empty stomach; calcium and iron can
interfere with absorption and should be separated as instructed.
• Thyroid storm may involve high fever, marked tachycardia, agitation, and gastrointestinal
symptoms; treat as an emergency.
• Long-term corticosteroids should not be stopped abruptly without prescriber direction
because adrenal suppression may occur.
