Which one of the following statements about beta-adrenoceptor antagonists is INCORRECT?Group of answer choicesThey cause fatigue during exercise due to decreased cardiac output and skeletal muscle perfusion.They decrease blood pressure by decreasing heart rate.They decrease blood pressure by inhibiting renin secretion thereby lowering blood volume.They are safe in asthmatics.

Which of the following statements is/are true regarding the long-term control of blood pressure?Question 8Select one or more:a.Aldosterone decreases water, sodium and chloride reabsorption at the kidney, increasing blood volume and blood pressure.b.Angiotensin II increases vasoconstriction of arterioles, increasing peripheral resistance and blood pressure.c.In response to falling blood pressure, levels of angiotensin II increase in the blood.d.Angiotensin II increases secretion of aldosterone from the adrenal cortex.e.The kidneys play an important role in the long-term control of blood pressure.

Select the correct statements. (Note that there may be more than one correct statement.)Group of answer choicesIncreased sympathetic activity results in an increased activation of α1 adrenoreceptors, which profoundly increases heart rate and therefore cardiac output.Statins decrease plasma LDL concentration because they inhibit an enzyme that is involved in hepatic cholesterol synthesis.Hypertension damages endothelium and therefore accelerates the development of atherosclerotic plaques.Systemic vasoconstriction increases total peripheral resistance and therefore increases mean arterial pressure, too.

Which one of the following statements regarding angiotensin AT1 receptor antagonists for the treatment of hypertension is correct?Group of answer choicesThey lower blood pressure via decreased angiotensin II levels.They decrease total peripheral resistance.They cause a dry cough.They decrease circulating angiotensin I levels.

During exercise, the heart rate ______ due to effects of the sympathetic nervous system.Multiple choice question.decreasesbecomes constantincreases

Clinical Corner: Beta-adrenergic blocking medications for exercising individuals with coronary artery disease  increase stroke volume. increase heart rate. interfere with epinephrine and norepinephrine receptor function. inhibit the actions of acetylcholine.
