Answer to Question 1

Correct Answer: 4
Rationale 1: Determinants of blood pressure such as blood viscosity mainly affect the systolic reading portion of the blood pressure.
Rationale 2: Determinants of blood pressure such as blood volume mainly affect the systolic reading portion of the blood pressure.
Rationale 3: Determinants of blood pressure such as pumping action of the heart mainly affect the systolic reading portion of the blood pressure.
Rationale 4: Peripheral vascular resistance especially affects diastolic blood pressure readings. A reading of 120/100 would be indicative of peripheral vascular resistance.

Answer to Question 2

Correct Answer: 1
Rationale 1: Phase 2 produces a muffled, whooshing, or swishing sound.
Rationale 2: Phase 5, the final phase, is where the sound disappears.
Rationale 3: Phase 1 of Korotkoff's sounds starts with a faint, clear tapping sound.
Rationale 4: Phase 3 is marked by an increased intensity of sound.
