Which determinant of blood pressure would explain a client's blood pressure reading of 120/100?
1. Blood viscosity
2. Blood volume
3. Pumping action of the heart
4. Peripheral vascular resistance
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.
