Solutions | A+ Graded Nursing Exam Resource
Introduction
This study guide contains 80 original multiple-choice questions designed to pre-
pare nursing students for the ATI Proctored Capstone Comprehensive B Exam
for the 2025/2026 academic year. Each question is aligned with the clinical con-
tent of the ATI Capstone Comprehensive B, covering critical nursing concepts,
patient care, and clinical decision-making. All questions include a verified cor-
rect answer and a detailed rationale to enhance understanding.
Practice Questions
Question 1. A nurse is assessing a client with suspected hypokalemia. Which
clinical manifestation should the nurse expect?
(a) Muscle cramps
(b) Increased deep tendon reflexes
(c) Hypertension
(d) Bradycardia
Correct Answer: (a) Muscle cramps
Rationale: Hypokalemia (low potassium levels) disrupts muscle
function, leading to muscle cramps, weakness, or dysrhythmias. In-
creased deep tendon reflexes are associated with hyperkalemia, hy-
pertension is not directly related, and tachycardia, not bradycardia,
is more common.
Question 2. A client with type 2 diabetes mellitus is prescribed metformin. Which
instruction should the nurse include?
(a) Take the medication with meals
(b) Avoid all carbohydrates
(c) Administer the medication via injection
(d) Monitor blood pressure daily
Correct Answer: (a) Take the medication with meals
1
, Rationale: Metformin should be taken with meals to reduce gas-
trointestinal side effects like nausea. Carbohydrates should be man-
aged, not avoided, insulin is injected, and blood pressure monitor-
ing is not specific to metformin.
Question 3. A nurse is caring for a client post-myocardial infarction. Which lab-
oratory value should the nurse monitor closely?
(a) Troponin I
(b) Hemoglobin A1c
(c) Serum sodium
(d) Platelet count
Correct Answer: (a) Troponin I
Rationale: Troponin I is a cardiac-specific marker elevated in my-
ocardial infarction, indicating heart muscle damage. Hemoglobin
A1c assesses long-term glucose control, sodium monitors fluid bal-
ance, and platelets are relevant for bleeding risk.
Question 4. A client with chronic obstructive pulmonary disease (COPD) is re-
ceiving oxygen at 2 L/min via nasal cannula. Which action should
the nurse take?
(a) Increase oxygen to 4 L/min
(b) Monitor for signs of oxygen toxicity
(c) Encourage pursed-lip breathing
(d) Place the client in a supine position
Correct Answer: (c) Encourage pursed-lip breathing
Rationale: Pursed-lip breathing helps prolong exhalation, reduc-
ing air trapping in COPD. Increasing oxygen without an order risks
CO2 retention, oxygen toxicity is unlikely at low flow, and supine
positioning may worsen dyspnea.
Question 5. A nurse is preparing to administer digoxin to a client with heart
failure. Which finding requires the nurse to withhold the dose?
(a) Heart rate of 58 bpm
(b) Blood pressure of 140/90 mmHg
(c) Potassium level of 4.0 mEq/L
2
, (d) Respiratory rate of 20 breaths/min
Correct Answer: (a) Heart rate of 58 bpm
Rationale: Digoxin slows the heart rate, and a rate below 60 bpm
indicates potential toxicity, requiring the dose to be withheld. The
blood pressure, potassium, and respiratory rate are within normal
limits.
Question 6. A client with a new diagnosis of hypertension is prescribed hydrochloroth-
iazide. Which dietary instruction should the nurse provide?
(a) Increase potassium-rich foods
(b) Avoid all sodium
(c) Limit fluid intake
(d) Increase calcium supplements
Correct Answer: (a) Increase potassium-rich foods
Rationale: Hydrochlorothiazide, a diuretic, can cause hypokalemia.
Potassium-rich foods (e.g., bananas) help maintain levels. Sodium
should be moderated, not eliminated, fluid restriction is unneces-
sary, and calcium is unrelated.
Question 7. A nurse is assessing a client with suspected appendicitis. Which
finding should the nurse report immediately?
(a) Rebound tenderness
(b) Mild nausea
(c) Temperature of 37.2°C (99°F)
(d) Soft abdomen
Correct Answer: (a) Rebound tenderness
Rationale: Rebound tenderness in the right lower quadrant sug-
gests peritoneal irritation, a hallmark of appendicitis requiring ur-
gent intervention. Mild nausea and low-grade fever are common,
and a soft abdomen is not concerning.
Question 8. A client is receiving heparin therapy for a deep vein thrombosis.
Which laboratory value should the nurse monitor?
(a) Activated partial thromboplastin time (aPTT)
(b) International normalized ratio (INR)
