A 45-year-old client presents with chest pain described as sharp, worse with
inspiration, and relieved when sitting forward. Which is the most likely diagnosis?
a. Myocardial infarction
b. Pulmonary embolism
c. Acute pericarditis
d. Gastroesophageal reflux disease
✔️ Correct Answer: C
Rationale:
Acute pericarditis typically presents with sharp pleuritic chest pain that improves
when leaning forward due to reduced pericardial pressure. MI pain is usually
pressure-like and not positional. PE can cause pleuritic pain but is often
,accompanied by hypoxia and risk factors. GERD is burning and meal-related. A
pericardial friction rub may be auscultated.
A client reports sudden shortness of breath, unilateral leg swelling, and pleuritic
chest pain. What is the most likely diagnosis?
a. Asthma exacerbation
b. Pulmonary embolism
c. Pneumonia
d. Heart failure
✔️ Correct Answer: B
Rationale:
The combination of dyspnea, pleuritic chest pain, and unilateral leg swelling
suggests deep vein thrombosis leading to pulmonary embolism. Asthma is
typically wheezing and reversible airflow obstruction. Pneumonia includes fever
and productive cough. Heart failure presents with bilateral fluid overload. D-dimer
and CT angiography are diagnostic.
A client presents with fever, productive cough, and dull chest pain. Lung
auscultation reveals crackles. What is the most likely diagnosis?
a. Pneumonia
b. COPD exacerbation
c. Pulmonary embolism
d. Tuberculosis
,✔️ Correct Answer: A
Rationale:
Pneumonia commonly presents with fever, productive cough, pleuritic chest pain,
and crackles due to alveolar infection. PE is usually nonproductive cough and
sudden onset. COPD is chronic with wheezing. TB is more chronic with night
sweats and weight loss. Chest X-ray and sputum culture confirm diagnosis.
A 60-year-old client has crushing chest pain radiating to the left arm with
diaphoresis. What is the priority diagnosis?
a. GERD
b. Myocardial infarction
c. Anxiety attack
d. Costochondritis
✔️ Correct Answer: B
Rationale:
Classic MI presentation includes crushing substernal chest pain radiating to
arm/jaw with diaphoresis. GERD is burning, anxiety is non-radiating and situational,
and costochondritis is reproducible with palpation. Immediate ECG and cardiac
enzymes are required.
A client reports wheezing, chest tightness, and episodic shortness of breath
triggered by allergens. What is the most likely diagnosis?
a. COPD
b. Asthma
, c. Pneumonia
d. Bronchiectasis
✔️ Correct Answer: B
Rationale:
Asthma is characterized by reversible airway obstruction with episodic wheezing
and triggers such as allergens. COPD is progressive and smoking-related.
Spirometry showing reversible obstruction confirms asthma.
A client presents with polyuria, polydipsia, and random glucose of 320 mg/dL.
What is the most likely diagnosis?
a. Diabetes insipidus
b. Type 2 diabetes mellitus
c. Hypothyroidism
d. Cushing syndrome
✔️ Correct Answer: B
Rationale:
Hyperglycemia with osmotic symptoms suggests diabetes mellitus. Diabetes
insipidus causes dilute urine without hyperglycemia. A1C and fasting glucose
confirm diagnosis.
A client presents with tremor, weight loss, heat intolerance, and tachycardia. What
is the most likely diagnosis?
