NSG 308/Pharm Exam 3 Cardiac Quiz 2

Which class of HTN medications would be most likely prescribed to a black patient who is genetically predisposed to be resistant to traditional medications such as ACEI/ARB used for monotherapy?

• Calcium Channel Blockers

• Beta Blockers

• ACE Inhibitors

• Alpha Blockers

What are the basic considerations when treating hypertension?

• - Requires lifetime treatment - 130/80 HTN threshold, 180/120 HTN crisis AT REST - Primary Factors that Affect BP: - Peripheral vascular resistance - Myocardial contractility - Heart rate - Blood volume

• - Only requires treatment during symptoms - 150/90 HTN threshold, 200/130 HTN crisis AT REST - Primary Factors that Affect BP: - Renal filtration rate - Liver enzymes - Blood glucose - Platelet count

• - Treatment is optional for mild cases - 120/70 HTN threshold, 160/100 HTN crisis AT REST - Primary Factors that Affect BP: - Oxygen saturation - White blood cell count - Cholesterol level - Body temperature

• - Only diet modification is necessary - 140/90 HTN threshold, 170/110 HTN crisis AT REST - Primary Factors that Affect BP: - Lung capacity - Insulin sensitivity - Calcium levels - Skin turgor

What is the function of baroreceptors in the vascular system (via SNS)?

• They sense pressure within large vessels, aorta/carotid, and relay that information to the vasomotor center in the brain.

• They sense pressure within peripheral vessels and relay that information to the vasomotor center in the brain.

• They sense pressure within large vessels, aorta/carotid, and relay that information to the temporal cortex in the brain.

• They filter waste products from the blood.

In people with hypertension, the "set point" of baroreceptors is high because high BP is what the baroreceptors think is 'normal.'

• True

• False

When medications lower BP, baroreceptors may respond by causing vasoconstriction and increasing HR in an attempt to raise BP.

• True

• False
