Introduction
This structured NUR 280 Comprehensive Review Comp 1 Exam study guide for 2026–2027
provides the complete layout for generating high-quality exam-style questions with correct
answers and rationales. It emphasizes foundational and advanced nursing principles, clinical
judgment, patient safety, and evidence-based practice critical to professional nursing practice and
successful academic course completion.
Answer Format & Certification Protocol
All correct answers in this guide are highlighted in bold and dark cyan, accompanied by detailed,
custom-written rationales explaining clinical nursing judgments, pharmacology protocols, client
safety, and why alternate choices are less appropriate. Per strict testing protocol, the distribution of
correct choice answers (A, B, C, D) is randomized and varied across all 100 questions to prevent
predictable patterns and ensure an authentic, high-fidelity exam simulation.

Domain: Medical-Surgical Nursing
Q1. A nurse is caring for a client who is in the oliguric phase of acute kidney injury (AKI).
Which of the following electrolyte imbalances should the nurse expect to find in the client's
lab results?
A) Hyperkalemia
B) Hypokalemia
C) Hypophosphatemia.
D) Hypernatremia
★ CLINICAL & ACADEMIC RATIONALE: In the oliguric phase of AKI, the kidneys are unable to excrete
potassium, leading to dangerous systemic hyperkalemia. Other common findings include hyponatremia (due to
dilution from water retention) and hyperphosphatemia.
Q2. A nurse is assessing a client who has a history of left-sided heart failure. Which of the
following clinical findings should the nurse expect?
A) Jugular venous distension.
B) Peripheral pitting edema.
C) Crackles in the lungs.
D) Hepatomegaly.
★ CLINICAL & ACADEMIC RATIONALE: Left-sided heart failure causes blood to back up into the pulmonary
circulation, leading to pulmonary congestion. Standard symptoms include crackles, dyspnea, orthopnea, and
cough. Right-sided heart failure leads to systemic congestion (JVD, peripheral edema, hepatomegaly).
Q3. A nurse is caring for a client with a history of Chronic Obstructive Pulmonary Disease
(COPD) who is receiving oxygen therapy. What is the primary physiological drive for
respiration in this client?
A) Hypoxia (low oxygen levels).
B) Respiratory acidosis.
C) Metabolic alkalosis.
D) Hypercapnia (elevated carbon dioxide levels).
★ CLINICAL & ACADEMIC RATIONALE: In clients with chronic COPD and carbon dioxide retention, the central
chemoreceptors become desensitized to high CO2 levels. Their primary drive to breathe is driven by peripheral
chemoreceptors sensing low oxygen levels (hypoxic drive); excessive oxygen administration can suppress this
drive.

Q4. A nurse is caring for a client who is 24 hours post-operative following a subtotal
thyroidectomy. Which of the following clinical findings indicates a potentially life-
threatening complication and requires immediate intervention?
A) Mild hoarseness when speaking.
B) Laryngeal stridor on inspiration.
C) Pain at the incision site scored 5 out of 10.
D) Moderate serosanguineous drainage on the dressing.
★ CLINICAL & ACADEMIC RATIONALE: Laryngeal stridor (a harsh, high-pitched inspiratory sound) indicates
acute airway obstruction. This can result from laryngeal nerve damage, tetany due to accidental parathyroid
gland removal (hypocalcemia), or hemorrhage compressing the trachea, representing an immediate emergency.
Q5. A nurse is assessing a client who presents with suspected Diabetic Ketoacidosis (DKA).
Which of the following breathing patterns should the nurse expect to observe?
A) Kussmaul respirations.
B) Apneustic breathing.
C) Cheyne-Stokes respirations.
D) Biot's respirations.
★ CLINICAL & ACADEMIC RATIONALE: Kussmaul respirations are deep, rapid, and sighing breaths. They
represent the body's compensatory mechanism to blow off excess carbon dioxide (acid) to correct the severe
metabolic acidosis of DKA.
Q6. A nurse is assessing a client with severe hypothyroidism. Which of the following clinical
findings is most characteristic of this condition? (Ref: MS-Q6)
A) Diarrhea and weight loss.
B) Bradycardia and cold intolerance.
C) Exophthalmos and tremors.
D) Tachycardia and heat intolerance.
★ CLINICAL & ACADEMIC RATIONALE: Severe hypothyroidism (myxedema) slows down metabolic processes,
leading to bradycardia, cold intolerance, weight gain, fatigue, constipation, and dry skin. Hyperthyroidism causes
the opposite (tachycardia, heat intolerance, weight loss).

Q7. A nurse is assessing a client with severe hypothyroidism. Which of the following clinical
findings is most characteristic of this condition? (Ref: MS-Q7)
A) Diarrhea and weight loss.
B) Exophthalmos and tremors.
C) Bradycardia and cold intolerance.
D) Tachycardia and heat intolerance.
★ CLINICAL & ACADEMIC RATIONALE: Severe hypothyroidism (myxedema) slows down metabolic processes,
leading to bradycardia, cold intolerance, weight gain, fatigue, constipation, and dry skin. Hyperthyroidism causes
the opposite (tachycardia, heat intolerance, weight loss).
Q8. A nurse is assessing a client with severe hypothyroidism. Which of the following clinical
findings is most characteristic of this condition? (Ref: MS-Q8)
A) Exophthalmos and tremors.
B) Tachycardia and heat intolerance.
C) Diarrhea and weight loss.
D) Bradycardia and cold intolerance.
★ CLINICAL & ACADEMIC RATIONALE: Severe hypothyroidism (myxedema) slows down metabolic processes,
leading to bradycardia, cold intolerance, weight gain, fatigue, constipation, and dry skin. Hyperthyroidism causes
the opposite (tachycardia, heat intolerance, weight loss).
Q9. A nurse is assessing a client with severe hypothyroidism. Which of the following clinical
findings is most characteristic of this condition? (Ref: MS-Q9)
A) Exophthalmos and tremors.
B) Tachycardia and heat intolerance.
C) Bradycardia and cold intolerance.
