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.
5. Renal function, fluids, and electrolytes
• Track urine output, daily weight, intake/output, edema, respiratory status, renal labs, and electrolytes. A falling urine
output with rising creatinine requires prompt review.
• Hyperkalemia can cause weakness and dangerous ECG changes such as peaked T waves; assess rhythm and
escalate urgently.
• Hypokalemia can cause weakness and dysrhythmias, particularly with diuretic use. Review potassium and relevant
renal data as ordered.
• Severe symptomatic hyponatremia can cause confusion or seizures. Treatment and sodium correction must be
carefully monitored.
• Hypernatremia requires assessment of cause and volume status with controlled correction; overly rapid correction
can cause harm.
• Dialysis clients with chest pain, hypotension, acute confusion, or breathing difficulty need immediate assessment
and the relevant emergency protocol.
