Hyperlipidemia is a category that encompasses both hypercholesterolemia and hypertriglyceridemia. Answer: True Feedback: Hyperlipidemia is a category that encompasses both hypercholesterolemia (increased levels of serum cholesterol) and hypertriglyceridemia (increased levels of serum triglycerides). 43. HMG-CoA reductase inhibitor drugs block HMG-CoA reductase, an enzyme that is involved in one of the steps in the production of cholesterol in the body. Answer: True Feedback: HMG-CoA reductase is an enzyme that is involved in one of the steps in the production of cholesterol in the body. HMG-CoA reductase inhibitor drugs block this enzyme. 44. High levels of HDL are undesirable, while high levels of LDL are desirable. Answer: False Feedback: High levels of HDL are desirable. High levels of LDL are undesirable. 45. By blocking an enzyme, ACE inhibitor drugs cause vasodilation and decrease the blood pressure against which the heart must pump. Answer: True Feedback: By blocking this enzyme, ACE inhibitor drugs cause vasodilation and decrease the blood pressure, the resistance against which the heart must pump. 46. In patients with angina pectoris, anticoagulant drugs are prescribed to prevent a blood clot that would cause a myocardial infarction. Answer: True Feedback: Anticoagulant drugs are used in patients with angina pectoris to prevent a blood clot that would cause a myocardial infarction. 47.

Answer: False Feedback: Drugs used to treat ventricular fibrillation have no effect if the heart has already stopped (asystole, cardiac arrest). 48. Most beta-blocker drugs, calcium channel blocker drugs, and peripheral vasodilator drugs can be given intravenously to quickly lower the blood pressure to treat patients in hypertensive crisis. Answer: True Feedback: Most beta-blocker drugs, calcium channel blocker drugs, and peripheral vasodilator drugs can be given intravenously to quickly lower the blood pressure. 49. Digitalis drugs have a positive inotropic effect in treating congestive heart failure because they increase the strength of contraction of the heart muscle. Answer: True Feedback: Digitalis drugs also inhibit the flow of positive sodium ions into the cell; instead, positive calcium ions flow in and this results in a stronger, more forceful contraction of the myocardial cells. This action is known as a positive inotropic effect. 50. The pain of angina pectoris occurs when the heart muscle cells die because of insufficient oxygenated blood. Answer: False Feedback: The pain of angina pectoris occurs when cells of the myocardium receive insufficient oxygenated blood to meet their needs. The pain of angina pectoris denotes cellular ischemia but not cellular death of the heart muscle cells. 51. All beta receptors are stimulated by the hormone epinephrine in response to stress or danger. Answer: True Feedback: All beta receptors are stimulated by the hormone epinephrine in response to stress or danger (the so-called “fight or flight” response). 52. In 1967 when it was approved by the FDA, propranolol became the first drug in the beta-blocker category. Answer: True Feedback: Propranolol was the first drug in the beta-blocker drug category. It was approved by the FDA in 1967 for treating hypertension. 53. After a myocardial infarction, drugs can be given to limit the extent of the dead tissue and then reverse the process of cellular death. Answer: False Feedback: When myocardial cell ischemia associated with angina pectoris is not treated, it may progress to cellular death, which is known as a myocardial infarction. Once the tissue has died, this process cannot be reversed. However, drugs can be given to limit the extent of the area of dead tissue and to improve the survival rate following a myocardial infarction. 54. Christine Zanzone has just discovered that she has a hyperlipidemia. Drug therapy, not lifestyle changes, is the first choice of treatment for hyperlipidemia. Answer: False Feedback: Dietary therapy rather than drug therapy is the first choice of treatment for hyperlipidemia. In addition, these lifestyle changes may be recommended: exercise, weight loss, decreased alcohol consumption, or cessation of smoking. If diet and lifestyle changes are not enough to decrease the cholesterol level, drug therapy is added. 55. Beta-blocker drugs block beta receptors in the blood vessels. This causes the blood vessels to constrict and this decreases the blood pressure in patients with hypertension. Answer: False Feedback: In patients with hypertension, beta-blocker drugs block the action of epinephrine on beta receptors and this slows the heart rate and dilates the blood vessels; both of these actions decrease the blood pressure. 56. The painting The Starry Night by Vincent van Gogh may show evidence of digitalis toxicity in the way in which the stars were painted. Answer: True Feedback: Vincent van Gogh's The Starry Night (1889) is felt by some to show evidence of digitalis toxicity in the way the Dutch painter depicted yellow-green halos around the stars. 57. The suffix –sartan is common to generic angiotensin II receptor blocker drugs. Answer: True Feedback: The suffix –sartan is common to generic angiotensin II receptor blocker drugs. 58. Alpha-blocker drugs are used to treat hypertension because they block alpha receptors in both the arteries and veins and cause them to dilate to lower the blood pressure. Answer: True Feedback: Alpha1 receptors are located in the peripheral blood vessels in both arteries and veins. Blocking these receptors causes both the arteries and veins to dilate, and this lowers the blood pressure. 59.

HMG-CoA reductase inhibitor drugs block this enzyme and are used to treat hypercholesterolemia. These drugs are also known as statin drugs. 61. Digoxin often causes toxicity because this drug has a short half-life. Answer: False Feedback: Nearly one-third of patients taking a digitalis drug develop symptoms of digitalis toxicity. This is because these drugs have a low therapeutic index (i.e., there is a narrow margin between the therapeutic dose and the toxic dose) and a long half-life. 62. A patient in hypertensive crisis has an extremely high blood pressure. Answer: True Feedback: A patient in hypertensive crisis exhibits an extremely high blood pressure. 63. Oatmeal in the diet is an effective way to reduce the cholesterol level of the blood. Answer: True Feedback: Oatmeal is effective in lowering the cholesterol level in the blood.

The American Heart Association recommends eating fish and taking fish oil supplements that contain omega-3 fatty acids to reduce cholesterol and triglyceride levels. Answer: False Feedback: Omega-3 fatty acids are found in the oil of cold water fish. While the American Heart Association recommends eating fish, it does not endorse the use of fish oil supplements. 68. The abbreviation HTN stands for ________. Answer: hypertension Feedback: Hypertension (HTN) is characterized by an increase in the systolic and/or diastolic blood pressure. 69. Aldosterone causes reabsorption of sodium and water from the kidney tubules back into the blood. Aldosterone receptor inhibitor drugs block this action and so these drugs are used to treat ________. Answer: hypertension Feedback: The action of aldosterone is to increase the reabsorption of sodium from the kidney tubules back into the blood. As sodium moves back into the blood, it brings water with it and this increases the blood pressure. Aldosterone receptor inhibitor drugs block the action of aldosterone and this lowers the blood pressure (to treat hypertension). 70. To be transported through the blood, cholesterol and triglycerides must bind to certain carrier molecules, which are known as __________. Answer: lipoproteins Feedback: To be transported through the blood, cholesterol and triglycerides must bind to certain carrier molecules, which are known as lipoproteins. 71. __________ drugs are also known as cardiac glycoside drugs because they have a molecular structure that consists of chains of glucose sugar known as glycosides and they are used to treat the heart (cardiac). Answer: Digitalis Feedback: Digitalis drugs are also known as cardiac glycoside drugs because they have a molecular structure that consists of chains of glucose sugars known as glycosides and they are used to treat the heart (cardiac). 72. ________ is the most frequently prescribed nitrate drug used to treat angina pectoris. Answer: nitroglycerin Feedback: The most frequently prescribed nitrate drug is nitroglycerin. 73. The generic drug used to treat ventricular arrhythmias and also to numb the skin when injected is known as ________. Answer: lidocaine Feedback: The antiarrhythmic drug lidocaine (Xylocaine) is also a topical anesthetic drug. It inhibits the flow of sodium into nerve cells. This stops electrical impulses along sensory nerves, and then there is no perception/transmission of pain. 74.

Explain why cardioselective beta-blocker drugs are different from regular betablocker drugs. Answer: Beta-blocker drugs block all beta1 and beta2 receptors. Cardioselective beta-blocker drugs are more selective in their action and block only beta1 receptors in the heart and beta2 receptors in the blood vessels (but not in the bronchi). 85. In the body, the hormone epinephrine has three actions, and the manufactured drug epinephrine has those same three actions. Describe one of the three actions. Answer: 1. Stimulating alpha receptors to constrict the peripheral blood vessels and raise the blood pressure. 2. Stimulating beta1 receptors in the heart to increase the heart rate and cardiac output. 3. Stimulating beta2 receptors in the lungs to relax bronchial smooth muscle, dilate the bronchi, and increase air flow to the lungs. 86. List at least three lifestyle changes that are suggested to patients before they are started on a drug for hypertension. Answer: The treatment of hypertension follows what is known as a stepped-care approach. Lifestyle changes are suggested first: Patients are asked to restrict the use of salt in cooking and at the table, or the physician may prescribe a low-salt diet to limit the total dietary sodium intake. In addition, the patient may be asked to lose weight, exercise, and stop smoking. If these measures cannot control the blood pressure, drugs are added to the treatment regimen. Often a diuretic drug is prescribed first. Test Bank for Understanding Pharmacology for Health Professionals Susan M. Turley 9780135145708, 9780133911268
