Exam Title: Santa Clara County Clinical Nurse Specialist Examination — Advanced Practice
Competency Assessment for Expert Clinical Judgment, Evidence-Based Systems Leadership, and
Interprofessional Collaboration Across Patient, Nursing, and Organizational Spheres of Influence
Section I: Nursing Science — Assessment, Diagnosis, and Planning (Questions 1–35)
Question 1
A 78-year-old patient is brought to the emergency department by family members who report a
sudden change in behavior over the past 48 hours. The patient is disoriented to time and place,
has difficulty following commands, and exhibits fluctuating levels of consciousness. The CNS
recognizes these findings as most consistent with:
A) Alzheimer's disease
B) Vascular dementia
C) Delirium
D) Major depressive disorder
-detailed answer 100% correct :- C
Rationale: Delirium is characterized by acute onset, fluctuating course, inattention, and altered
consciousness. Alzheimer's disease and vascular dementia have insidious, progressive onsets.
Depression presents with mood disturbance rather than acute cognitive fluctuation.
Question 2
Which nursing theorist is most closely associated with the concept of self-care deficits and the
nurse's role in supporting patients to meet their own care needs?
A) Hildegard Peplau
B) Dorothea Orem
C) Betty Neuman
D) Sister Callista Roy
-detailed answer 100% correct :- B
Rationale: Orem's Self-Care Deficit Theory focuses on the patient's ability to perform self-care
and the nurse's role in providing assistance when deficits exist. Peplau focused on interpersonal
relations, Neuman on systems and stress, and Roy on adaptation.

Question 3
A patient presents with jugular venous distention, hepatomegaly, and bilateral lower extremity
edema. The CNS recognizes these findings are indicative of:
A) Left-sided heart failure
B) Right-sided heart failure
C) Pericarditis
D) Pulmonary embolism
-detailed answer 100% correct :- B
Rationale: Right-sided heart failure presents with signs of systemic venous congestion including
jugular venous distention, hepatomegaly, peripheral edema, and ascites. Left-sided heart failure
presents with pulmonary congestion (crackles, dyspnea, orthopnea).
Question 4
A patient with COPD and hypercapnia is receiving oxygen therapy. The CNS understands that the
most appropriate target for SpO₂ in this patient is:
A) 94-98%
B) 88-92%
C) 100%
D) > 95%
-detailed answer 100% correct :- B
Rationale: In patients with COPD and chronic hypercapnia, oxygen should be titrated to achieve
SpO₂ of 88-92% to avoid suppressing the hypoxic respiratory drive and worsening hypercapnia.
Higher targets may lead to CO₂ retention and respiratory acidosis.
Question 5
A patient with diabetic ketoacidosis (DKA) has a blood glucose of 580 mg/dL, anion gap of 26,
and serum bicarbonate of 8 mEq/L. Which intervention should the CNS prioritize?
A) Intravenous insulin bolus
B) Intravenous fluid resuscitation with normal saline
C) Oral hypoglycemic agents
D) Sodium bicarbonate administration
-detailed answer 100% correct :- B
, 4
Rationale: The priority in DKA is volume resuscitation with normal saline to restore intravascular
volume and improve tissue perfusion. Insulin therapy should follow fluid resuscitation. Sodium
bicarbonate is rarely indicated and oral agents are inappropriate.
Question 6
Which of the following is a normal age-related change in the cardiovascular system?
A) Increased cardiac output
B) Decreased arterial compliance
C) Decreased systolic blood pressure
D) Increased maximal heart rate
-detailed answer 100% correct :- B
Rationale: Age-related cardiovascular changes include decreased arterial compliance (increased
stiffness), increased systolic blood pressure, decreased cardiac output, and decreased maximal
heart rate.
Question 7
The CNS is teaching a patient with hypertension about lifestyle modifications. Which statement
indicates the patient understands the teaching?
A) "I only need to take my medication when my blood pressure is high."
B) "I should limit my sodium intake to less than 2,300 mg per day."
C) "I can stop exercising once my blood pressure is normal."
D) "Alcohol has no effect on blood pressure."
-detailed answer 100% correct :- B
Rationale: The American Heart Association recommends limiting sodium intake to less than
2,300 mg per day for blood pressure management. Medications should be taken consistently
regardless of symptoms, exercise should be ongoing, and alcohol intake should be limited.
Question 8
A postoperative patient develops sudden-onset dyspnea, pleuritic chest pain, tachycardia, and
hemoptysis. The CNS suspects:
A) Atelectasis
B) Pulmonary embolism
