Cardiovascular Assessment Questions Questions
Question 1 of 5
50 yo patient presents with numbness of the first three fingers of the right hand. Which of the following findings on physical exam are supportive of carpal tunnel syndrome?
Correct Answer: A
Rationale: Tinel's sign (symptoms with tapping) is a classic finding in carpal tunnel syndrome, involving median nerve compression.
Question 2 of 5
Suspecting acute Pneumocystis pneumonia, which is the most important study to immediately order?
Correct Answer: A
Rationale: ABGs are critical in assessing respiratory function and oxygenation status in suspected Pneumocystis pneumonia.
Question 3 of 5
Man in ER coma. Labs: Serum Na 131 mEq/L, K 2.9 mEq/L, Cl 70 mEq/L, CO2 21 mEq/L, blood urea nitrogen 34, creatinine 1.4 mg/dl, glucose 240 mg/dl, serum osmolality 320 mOsm/kg H2O, serum ketones weakly+, pH 7.53, PaCO2 25, and serum albumin 3.8. Which ONE of the following choices BEST describes his acid-base disturbance?
Correct Answer: D
Rationale: The combination of high anion gap metabolic acidosis from ketones, metabolic alkalosis from vomiting or diuretic use, and respiratory alkalosis from compensatory mechanisms explains the complex disturbance.
Question 4 of 5
Which of the following is associated with inflammatory joint pain?
Correct Answer: A
Rationale: Prolonged morning stiffness improving with use is classic for inflammatory joint pain (e.g., RA), unlike mechanical pain (worse with use) or osteoarthritis features (bone hypertrophy, osteophytes), per rheumatologic diagnostic criteria.
Question 5 of 5
Low cardiac output to the kidneys stimulates the release of _____ from juxtaglomerular cells.
Correct Answer: D
Rationale: When cardiac output is reduced, juxtaglomerular cells in the kidney release renin and initiate the renin-angiotensin-aldosterone cascade leading to salt and water retention by the kidney. Aldosterone is not released from juxtaglomerular cells. Norepinephrine is not released by cells within the kidney. Angiotensin is not involved in the process of cellular release within the kidneys.
