COMPREHENSIVE CLINICAL REASONING
EXAMINATION
Adult and Pediatric Primary Care Case Studies
Question 1
Lisa Jones, a 56-year-old female, presents for a blood pressure recheck. Her readings
today are 148/92 mmHg and 150/88 mmHg. She has a history of hypertension and has
been taking lisinopril 10 mg daily. Which assessment finding is most important for the
nurse to evaluate before adjusting her antihypertensive therapy?
A. Serum potassium level
B. Serum creatinine level
C. Heart rate and rhythm
D. Blood pressure in both arms
💫RATIONALE✔️✔️: Before adjusting antihypertensive therapy, it is essential to assess
renal function with serum creatinine and blood urea nitrogen, as ACE inhibitors can
affect renal perfusion. While potassium, heart rate, and bilateral blood pressures are
important, evaluating renal function is critical to ensure safe medication adjustment.
💫ANSWER✔️✔️: B. Serum creatinine level
Question 2
,Lisa Jones reports occasional dizziness when standing up quickly. She is concerned
about her blood pressure medication. Which instruction should the nurse provide?
A. "Increase your fluid intake to 3 liters per day."
B. "Rise slowly from sitting or lying positions."
C. "Take your blood pressure medication at bedtime."
D. "Stop taking your medication if you feel dizzy."
💫RATIONALE✔️✔️: Orthostatic hypotension is a common side effect of
antihypertensive medications. Teaching the patient to rise slowly from sitting or lying
positions allows time for blood pressure regulation and prevents falls. Fluid intake
should be adequate but excessive intake may not be necessary.
💫ANSWER✔️✔️: B. "Rise slowly from sitting or lying positions."
Question 3
Frances Drake-Chamberlain (Maura Smith), a 68-year-old female, presents with
dizziness. She reports episodes of feeling lightheaded, especially when turning her head
quickly. Which assessment should the nurse prioritize?
A. Orthostatic blood pressure measurements
B. Carotid artery auscultation
C. Romberg test
D. Otoscopic examination
💫RATIONALE✔️✔️: Dizziness associated with head movement suggests possible
carotid sinus hypersensitivity or vertebrobasilar insufficiency. Carotid artery auscultation
for bruits is a priority assessment to identify carotid stenosis, which can cause dizziness
and syncope.
💫ANSWER✔️✔️: B. Carotid artery auscultation
Question 4
,Frances Drake-Chamberlain's blood pressure is 112/68 mmHg sitting and 100/62 mmHg
standing. She reports feeling dizzy upon standing. Which intervention is most
appropriate?
A. Increase her antihypertensive medication
B. Encourage her to decrease fluid intake
C. Instruct her to rise slowly from sitting to standing
D. Start her on a beta-blocker
💫RATIONALE✔️✔️: The patient is experiencing orthostatic hypotension, as evidenced
by a significant drop in blood pressure upon standing. The priority intervention is to
teach the patient to rise slowly to allow for compensatory mechanisms. Medication
adjustment may be needed but should be evaluated by the healthcare provider.
💫ANSWER✔️✔️: C. Instruct her to rise slowly from sitting to standing
Question 5
James Taylor, a 39-year-old male, presents with fatigue and shortness of breath. He
reports that his symptoms have worsened over the past 2 weeks. He has a history of
asthma but reports using his rescue inhaler more frequently. Which assessment finding
is most concerning?
A. Respiratory rate of 22 breaths per minute
B. Oxygen saturation of 90% on room air
C. Heart rate of 96 beats per minute
D. Peak expiratory flow rate of 65% of personal best
💫RATIONALE✔️✔️: An oxygen saturation of 90% on room air indicates hypoxemia
and is the most concerning finding. In a patient with worsening asthma symptoms,
hypoxemia suggests significant airway obstruction and potential respiratory
compromise requiring immediate intervention.
💫ANSWER✔️✔️: B. Oxygen saturation of 90% on room air
, Question 6
James Taylor's peak expiratory flow rate is 55% of his personal best. Which action should
the nurse take first?
A. Administer a bronchodilator and re-evaluate
B. Notify the healthcare provider immediately
C. Obtain a chest x-ray
D. Instruct the patient to rest and drink fluids
💫RATIONALE✔️✔️: A peak expiratory flow rate below 60% of personal best indicates
a severe asthma exacerbation requiring immediate treatment. The nurse should
administer a bronchodilator and evaluate response. This is a priority action to improve
airflow.
💫ANSWER✔️✔️: A. Administer a bronchodilator and re-evaluate
Question 7
Jamie Feldman, a 67-year-old male, presents with stable angina and shortness of breath.
He reports chest pressure with exertion that resolves with rest. Which medication is
most appropriate for acute symptom relief?
A. Aspirin 81 mg daily
B. Metoprolol 25 mg twice daily
C. Nitroglycerin 0.4 mg sublingual
D. Atorvastatin 40 mg daily
💫RATIONALE✔️✔️: Sublingual nitroglycerin is the medication of choice for acute
relief of angina symptoms. It rapidly vasodilates coronary arteries, reducing myocardial
oxygen demand and relieving chest pain. The other medications are used for long-term
management.
💫ANSWER✔️✔️: C. Nitroglycerin 0.4 mg sublingual
