Questions & Verified Answers
1. A nurse is caring for a client with left-sided heart failure. Which of the following clinical
manifestations should the nurse expect to find?
A. Peripheral edema
B. Crackles in the lungs
C. Jugular venous distension (JVD)
D. D. Hepatomegaly
Answer: B
Rationale: Left-sided heart failure causes blood to back up into the pulmonary system, leading to pulmonary
congestion and crackles. Options A, B, and D are signs of right-sided heart failure. Recognizing this principle
allows the nurse to prioritize care, anticipate complications, and provide accurate patient education.
2. Which lab value is the most important to monitor for a patient receiving a heparin infusion for
a pulmonary embolism?
A. Prothrombin time (PT)
B. International Normalized Ratio (INR)
C. Activated partial thromboplastin time (aPTT)
D. Platelet count
Answer: C
Rationale: aPTT is used to monitor the therapeutic effect of heparin. PT and INR are used to monitor Warfarin
therapy. Applying this knowledge in clinical settings supports safe, evidence-based practice and improves
patient outcomes. This is an important clinical concept because selecting the correct answer (C) requires
understanding both the pathophysiology and the practical nursing implications.
3. A client is diagnosed with type 1 diabetes mellitus. The nurse should teach the client that
which of the following is a symptom of hypoglycemia?
A. Extreme thirst
B. Shakiness and diaphoresis
C. Frequent urination
D. Fruity-smelling breath
Answer: B
Rationale: Hypoglycemia triggers the sympathetic nervous system, causing shakiness, sweating (diaphoresis),
and palpitations. Thirst and fruity breath are signs of hyperglycemia/DKA. Exam questions often test the ability
to distinguish this concept from closely related distractors, making a clear rationale essential for mastery.

4. Which of the following electrolyte imbalances is a client with chronic kidney disease most at
risk for developing?
A. Hypokalemia
B. Hypomagnesemia
C. Hyponatremia
D. Hyperkalemia
Answer: D
Rationale: In chronic kidney disease, the kidneys’ ability to excrete potassium is impaired, leading to
hyperkalemia, which can cause dangerous cardiac arrhythmias. This is an important clinical concept because
selecting the correct answer (D) requires understanding both the pathophysiology and the practical nursing
implications. Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide
accurate patient education.
5. When caring for a patient with a chest tube, which observation requires immediate
intervention?
A. Intermittent bubbling in the water seal chamber
B. Tidaling in the water seal chamber with respiration
C. Constant, vigorous bubbling in the water seal chamber
D. Drainage of 50 mL of serosanguinous fluid in 2 hours
Answer: C
Rationale: Constant bubbling in the water seal chamber indicates a persistent air leak in the system or the
patient’s thorax. Intermittent bubbling is normal for a pneumothorax. This is an important clinical concept
because selecting the correct answer (C) requires understanding both the pathophysiology and the practical
nursing implications.
6. A patient has a pH of 7.30, PaCO2 of 52 mmHg, and HCO3 of 24 mEq/L. How should the nurse
interpret these ABG results?
A. Metabolic acidosis
B. Respiratory acidosis
C. Respiratory alkalosis
D. Metabolic alkalosis
Answer: B
Rationale: A pH below 7.35 indicates acidosis. A high PaCO2 (above 45) indicates a respiratory cause. Since
the HCO3 is normal, it is uncompensated respiratory acidosis. Exam questions often test the ability to
distinguish this concept from closely related distractors, making a clear rationale essential for mastery. Applying
this knowledge in clinical settings supports safe, evidence-based practice and improves patient outcomes.
