BIOD 121 Case Study Module 5: Questions & Answers
1. Fred’s blood pressure is measured at 160/90. According to the
American Heart Association (AHA) guidelines, how would this reading
be classified?
A. Normal
B. Elevated
C. High (Stage 1)
D. High (Stage 2)
• Correct Answer: D
• Rationale: Fred’s blood pressure of 160/90 is considered high
(Stage 2). Normal blood pressure is defined as less than 120
systolic and less than 80 diastolic.
2. Which of the following best describes the condition known as Atrial
Fibrillation (A-Fib)?
A. A complete stoppage of the heart's electrical signals.
B. A condition where the heart's lower chambers beat too slowly.
C. A heart rhythm problem where the upper chambers beat irregularly
and often too fast.
, D. Hardening of the arteries due to calcium buildup.
• Correct Answer: C
• Rationale: Atrial fibrillation is an irregular atrial heart rhythm
where the upper chambers beat irregularly and often too fast,
which can reduce pumping efficiency and increase the risk of
stroke.
3. Why is high blood pressure frequently referred to as the "silent
killer"?
A. It causes sudden, sharp pain that stops quickly.
B. It often has no noticeable symptoms while still damaging the body.
C. It only affects people while they are sleeping.
D. It cannot be detected by standard medical equipment.
• Correct Answer: B
• Rationale: Hypertension is called the "silent killer" because
individuals may feel fine and have no symptoms, yet the
condition can damage the body for years before serious problems
appear.
