Answers and Rationales

1. What is the most common chronic condition seen in primary care settings?
A. Elevated blood pressure or hypertension
B. Renal disease
C. Cardiovascular disease
D. Chronic kidney disease

ANS: A
Page: 9
Elevated blood pressure is also known as hypertension. Hypertension is the most common
chronic condition seen in primary care settings. Hypertension can lead to more serious conditions
such as cardiovascular disease, renal disease, and, if left untreated, possible death.

2. What is the national goal of Healthy People 2020?
A. To report cardiovascular disease instances
B. To increase the number of people who have had their blood pressure measured and
have reported it within normal limits
C. To increase the number of people who record chronic kidney disease
D. To increase the number of people who have reported urinary tract obstructions

ANS: B
Page: 9
The Healthy People of 2020 national goal objective is to increase the number of people who have
had their blood pressure previously measured within the past two years and who have reported it
normal. A normal blood pressure reading is classified as 120/80.

3. What is the definition of blood pressure?

A. Contraction of the heart
B. Elevated blood pressure
C. Force exerted against arterial walls by blood as it circulates through the body
D. No contraction of the heart

ANS: C

Chapter 1 Hypertension

Page: 10
Blood pressure is the definition of force exerted against the arterial walls by blood as it circulates
through the body. Systolic pressure is the force or contraction of the heart. Diastole is the
pressure in the arteries when the heart fills and rests between beats.

4. What is the proper formula for cardiac output?

A. CO = BP/PVR
B. CO × SV
C. CO = SV × HR
D. CO × SV × HR

ANS: A
Page: 10
Blood pressure is dependent upon many factors such as cardiac output and peripheral vascular
resistance (PVR). The correct formula for cardiac output is expressed as CO = BP/PVR. This
equation shows the relationship of blood flow through the body and blood pressure in the
arteries.

5. How many liters/min of blood is pumped by the heart in a healthy adult?

A. 4 liters/min
B. 5 liters/min
C. 6 liters/min
D. 7 liters/min

ANS: B
Page: 10
The average healthy adult has about 5 liters/min pumped by the heart through cardiac output.
This number can be calculated by multiplying the stroke volume (which is the amount of blood
pumped in each contraction) and by the heart rate.

6. Which two systems are directly dependent on normal blood pressure?
A. Renal and Endocrine system
B. Reproductive system
C. Integumentary system
D. Lymphatic system

ANS: A

, 7
Best: Advanced Clinical Concepts
Chapter 1 Hypertension

Page: 10

The renal and endocrine system are especially important in regulating your blood pressure
because the Renin-angiotensin-aldosterone system (RAAS) maintains function of normal blood
pressure. The RAAS mechanism decreases circulating blood volume and can decrease blood
pressure to maintain normal levels. In the endocrine system the adrenal glands are responsible
for secreting corticosteroids and maintaining normal blood pressure.

7. According to the AHA (American Heart Association), what is the normal level for blood pressure?
A. 130/90
B. 120/80
C. 140/90
D. 150/90

ANS: B
Page: 11
According to the AHA the normal blood pressure readings of systolic and diastolic is 120/80.
Essential hypertension is classified as greater than 140/90. Genetics, environment, and aging all
have effects on essential hypertension.

8. What causes an increased stiffness of arteries in aging individuals?
A. Shortening of telomeres
B. Lose elasticity
C. Decreased blood pressure
D. Low cardiac output

ANS: A
Page: 13
During aging, the telomere of your DNA shortens. This causes an increase in stiffness of the
arteries which then increases the pulse pressure. In aging, your arteries lose elasticity and decrease
renal function. Blood pressure also increases with age and can lead to hypertension as well.

9. What diet is recommended for lowering blood pressure and is high in fruits and vegetables?
A. Weight Watchers
B. Keto
C. DASH
D. South Beach

, 8
Best: Advanced Clinical Concepts
Chapter 1 Hypertension

ANS: C
Page: 14
The DASH diet also known as the Dietary Approaches to Stop Hypertension is known to be
effective in lowering blood pressure, reducing fat, and is high in fruits and vegetables. The DASH
diet also lowers sodium intake.

10. What are the choices of medications to manage hypertension (HTN)?
A. Cost
B. Limitations of adverse effects
C. The presence of other risk factors
D. All the above

ANS: D
Page: 15
The choices of medication to manage HTN is based on cost, limitations to adverse effects of the
medication, the patient’s HTN classification, and the presence of other risk factors (obesity,
smoking, age, family history).

11. What is the main function of beta blockers?
A. To lower blood pressure
B. To increase blood pressure
C. Increase heart rate
D. Increase pulse pressure

ANS: A
Page: 15-16
Beta blockers main function is to lower blood pressure. Beta blockers lower pressure by
decreasing the cardiac workload through negative chronotropic and inotropic effects.
Chronotropic effects from medications change the electrical conduction system of the heart, and a
negative chronotropic effect decreases the heart rate, and lowers blood pressure. Inotropic effects
weaken the force of the heart and lowers blood pressure.

12. What is the main function of calcium channel blockers?
A. Vascular constriction
B. Vascular dilation

, 9
Best: Advanced Clinical Concepts
Chapter 1 Hypertension

C. Increase blood pressure
D. Increase pulse rate

ANS: B
Page: 16
Calcium channel blockers main function is vasodilation. Calcium channel blockers work to block
calcium influx into the cell, which then causes vascular dilation. Calcium channel blockers are
absorbed and metabolized by the liver.

1 13. What is the main function of diuretics?
A. To increase blood pressure
B. To decrease blood pressure
C. Vasodilate
D. Vasoconstrict

ANS: B
Page: 16
Diuretics main function is to lower blood pressure by decreasing the extracellular fluid volume in
a cell. Diuretics increase the amount of water that the body releases which is excreted through
urine.

14. What is an example of an adrenergic drug classification?
A. Dopamine
B. Losartan
C. Diltiazem
D. Hydralazine

ANS: A
Page: 18
Adrenergic drugs activate sympathomimetic responses. This drug promotes the stimulation of the
sympathetic nerves. Dopamine is an example of an adrenergic drug. This drug also helps with
arrythmias, hypotension, and headaches.

15. What is an example of a vasodilator drug classification?
A. Dopamine
B. Losartan

, 10
Best: Advanced Clinical Concepts
Chapter 1 Hypertension

C. Diltiazem
D. Hydralazine

ANS: D
Page: 19
Hydralazine is an example of a vasodilator drug. Vasodilators act directly on the peripheral
arteries. Vasodilators lower blood pressure and decrease the afterload in heart function.
Vasodilators help with tachycardia, dizziness, drowsiness, and headaches.
