Cardiovascular Assessment Questions Questions
Question 1 of 5
Most common cause of death in patient's undergoing elective AAA repair is:
Correct Answer: A
Rationale: Cardiovascular events, such as myocardial infarction, are the most common cause of death in elective AAA repair due to underlying atherosclerosis and perioperative stress.
Question 2 of 5
Which of the following mechanisms best explains how antimetabolites work in cancer treatment?
Correct Answer: D
Rationale: Antimetabolites (e.g., 5-FU, methotrexate) mimic normal substrates, competing for enzyme sites or incorporating into DNA/RNA, disrupting synthesis. Other options describe different drug classes (e.g., topoisomerase inhibitors, tyrosine kinase inhibitors).
Question 3 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 4 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 5 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.
