Question 1
Bradycardia is defined as a resting heart rate at or below which value?
Correct Answer:
60 BPM or Lower
Explanation:
Bradycardia means a heart rate that is slower than normal when at rest. For adults, the lower limit of normal is about 60 beats per minute. When the resting pulse is at or below that value, it’s considered bradycardic. That’s why the correct threshold is 60 BPM or lower: it includes all rates that fall at or below the normal cutoff. Values above 60 are not bradycardia, while anything at or below 60 captures slower-than-normal rates, such as 58 or 40, which can be bradycardic depending on symptoms and context. Some people with very low rates can be asymptomatic athletes or may have underlying conditions, so the exact clinical significance depends on the overall picture.
Question 2
What does the T Wave on an ECG represent?
Correct Answer:
Recovery or relaxation of the ventricles
Explanation:
On an ECG, each wave reflects a phase of the heart’s electrical cycle. The T wave specifically marks ventricular repolarization—the ventricles returning to their resting state after contracting. In other words, the T wave represents the recovery or relaxation of the ventricles in preparation for the next heartbeat. The AV node delay is seen earlier as part of the PR interval, and atrial depolarization is the P wave, not the T wave. So the T wave signals the ventricles finishing their electrical reset and relaxing.
Question 3
In which organ does oxygen exchange occur in the circulatory system?
Correct Answer:
Lungs
Explanation:
Gas exchange for oxygen happens in the lungs, specifically at the alveoli. In these tiny air sacs, oxygen from inhaled air diffuses across the thin alveolar-capillary membrane into the blood, while carbon dioxide diffuses from the blood into the alveolar air to be exhaled. This process occurs as part of the pulmonary circulation, with deoxygenated blood from the heart’s right side reaching the lungs, picking up oxygen, and returning to the heart to be circulated to the rest of the body. The other organs listed—liver, spleen, and kidneys—have important roles in metabolism, immunity, and waste filtration, but they are not the sites where oxygen is exchanged between air and blood.
Question 4
Which arterial pulse is located at the top of the foot?
Correct Answer:
Dorsalis pedis
Explanation:
Locating arterial pulses hinges on matching the pulse to a named artery based on its surface course. The pulse you feel on the top of the foot comes from the dorsalis pedis artery, a continuation of the anterior tibial artery as it crosses the ankle and travels along the dorsum of the foot toward the toes. It’s typically palpated on the dorsum, near the midfoot and just lateral to the extensor hallucis longus tendon. This site is commonly used to assess peripheral circulation. If it’s not palpable, the posterior tibial pulse behind the medial malleolus can be an alternative. The carotid pulse is in the neck, the radial pulse is at the wrist, and the posterior tibial pulse is behind the ankle, not on the top of the foot.
Question 5
Stable Angina is the most common type and usually lasts
Correct Answer:
5 minutes or less
Explanation:
Stable angina episodes are brief and self-limited, reflecting transient, reversible ischemia from a fixed narrowing. Because these episodes are provoked by exertion or stress and relieved by rest or nitroglycerin, they typically last five minutes or less. If chest discomfort lasts longer than several minutes or occurs at rest, it suggests an unstable pattern or evolving acute coronary syndrome that needs urgent evaluation. This short, predictable duration helps distinguish stable angina from more dangerous conditions like unstable angina or myocardial infarction.
