Question 1
A 72-year-old patient presents with acute onset of confusion, fever, and urinary frequency. The
Clinical Nurse Specialist recognizes that the most likely diagnosis is:
A) Alzheimer's disease
B) Vascular dementia
C) Delirium secondary to urinary tract infection
D) Major depressive disorder
-detailed answer 100% correct :- C
Rationale: Delirium is an acute, fluctuating disturbance in attention and awareness that often
results from an underlying medical condition such as infection. In elderly patients, urinary tract
infections are a common cause of delirium. Alzheimer's disease and vascular dementia have
insidious onsets, while depression presents with mood symptoms rather than acute confusion
and fever.
Question 2
Which nursing theory emphasizes the importance of the therapeutic nurse-patient relationship
and interpersonal processes?
A) Orem's Self-Care Deficit Theory
B) Peplau's Interpersonal Relations Theory
C) Neuman's Systems Model
D) Roy's Adaptation Model
-detailed answer 100% correct :- B
Rationale: Peplau's Interpersonal Relations Theory focuses on the nurse-patient relationship as
the foundation of nursing practice, emphasizing therapeutic communication and interpersonal
processes. Orem's theory centers on self-care, Neuman's on stress and coping, and Roy's on
adaptation.

Question 3
A CNS is performing a comprehensive assessment on a patient with newly diagnosed heart
failure. Which finding is most indicative of right-sided heart failure?
A) Crackles in the lung bases
B) Paroxysmal nocturnal dyspnea
C) Peripheral edema and jugular venous distention
D) Orthopnea
-detailed answer 100% correct :- C
Rationale: Right-sided heart failure presents with peripheral edema, jugular venous distention,
and hepatomegaly due to fluid backup into the systemic venous system. Crackles, paroxysmal
nocturnal dyspnea, and orthopnea are characteristic of left-sided heart failure.
Question 4
The CNS is developing a care plan for a patient with chronic obstructive pulmonary disease
(COPD). Which intervention is most appropriate for managing hypercapnic respiratory failure?
A) Administer high-flow oxygen to maintain SpO₂ > 98%
B) Encourage deep breathing exercises every hour
C) Initiate non-invasive positive pressure ventilation (NIPPV)
D) Restrict fluid intake to 1 liter per day
-detailed answer 100% correct :- C
Rationale: NIPPV improves ventilation and reduces CO₂ retention in hypercapnic COPD patients.
High-flow oxygen may suppress the respiratory drive in patients who are chronic CO₂ retainers.
Deep breathing exercises alone are insufficient for acute respiratory failure.
Question 5
A patient with diabetic ketoacidosis (DKA) presents with a blood glucose of 650 mg/dL, anion
gap of 28, and serum bicarbonate of 10 mEq/L. The CNS prioritizes which intervention first?
A) Administer intravenous insulin bolus
B) Initiate intravenous fluid resuscitation
C) Administer sodium bicarbonate
D) Start oral hypoglycemic agents
-detailed answer 100% correct :- B
, 4
Rationale: The priority intervention in DKA is fluid resuscitation to restore intravascular volume
and improve tissue perfusion. Insulin therapy is initiated after fluid replacement, and sodium
bicarbonate is rarely indicated. Oral agents are not appropriate in acute DKA.
Question 6
Which of the following is a normal age-related physiological change in the older adult?
A) Increased glomerular filtration rate
B) Decreased chest wall compliance
C) Increased cardiac output
D) Increased muscle mass
-detailed answer 100% correct :- B
Rationale: Age-related changes include decreased chest wall compliance, reduced vital capacity,
and increased residual volume. Glomerular filtration rate decreases, cardiac output decreases,
and muscle mass decreases with aging.
Question 7
The CNS is educating a patient about hypertension management. Which statement indicates the
patient understands the teaching?
A) "I should check my blood pressure only when I feel dizzy."
B) "I will take my medication every morning even if I feel fine."
C) "I can stop my medication once my blood pressure is normal."
D) "I only need to restrict salt if my blood pressure is high."
-detailed answer 100% correct :- B
Rationale: Adherence to antihypertensive medication is essential regardless of symptoms.
Hypertension is often asymptomatic, and stopping medication can lead to rebound
hypertension and increased cardiovascular risk.
Question 8
A postoperative patient develops sudden shortness of breath, pleuritic chest pain, and
tachycardia. The CNS suspects:
A) Atelectasis
B) Pulmonary embolism
