Chapter 25 : Caring for Clients With Disorders of Coronary and Peripheral Blood Vessels Questions
Question 1 of 5
In the treatment of coronary artery disease (CAD), medications are often ordered to control blood pressure in the client. Which of the following is a primary purpose of using beta-adrenergic blockers in the nursing management of CAD?
Correct Answer: B
Rationale: Beta-adrenergic blockers are used in the treatment of CAD to decrease the consumption of myocardial oxygen by reducing heart rate and workload of the heart. Nitrates are used for vasodilation. Anti-lipid drugs (such as statins and B vitamins) are used to decrease homocysteine levels. ACE inhibitors inhibit the conversion of angiotensin.
Question 2 of 5
A client is prescribed a nitroglycerin transdermal patch to treat angina. Which statement does the nurse include when reinforcing medication teaching to the client prior to discharge?
Correct Answer: C
Rationale: A transdermal nitroglycerin patch is prescribed for the prevention of angina pectoris. Nitroglycerin transdermal patches are typically applied for 12 to 14 hours, and then removed for the same amount of time. Though it is true that common adverse effects of nitroglycerin are headaches and contact dermatitis and that there is less demand on the heart when the client rests, these are not the reasons for applying and removing the patch for the same length of time in a 24-hour period.
Question 3 of 5
Clients taking vasodilator drugs have a greater risk for postprandial hypotension. Which of the following is the best nursing explanation for this phenomenon?
Correct Answer: B
Rationale: During digestion, blood is diverted to the GI tract which decreases cerebral blood flow and increases potential of orthostatic hypotension. Although gravity does pull blood to the lower extremities while sitting, this is not the primary concern with postprandial hypotension. Decreased peripheral blood flow does not result in postprandial hypotension. Bronchospasms are associated more with asthma not diversion of blood flow.
Question 4 of 5
A client with a strong family history of coronary artery disease asks the nurse how to reduce the risk of developing the disorder. Which is the best response by the nurse?
Correct Answer: D
Rationale: Although moderation is the key, this does not provide specific options for this client such as regular exercise and managing stress and cholesterol levels. The reverse lipid drug sounds good but is not available or approved by the FDA. Soy products have limited benefits for cholesterol control.
Question 5 of 5
A client, who has undergone a percutaneous transluminal coronary angioplasty (PTCA), has received discharge instructions. Which statement by the client would indicate the need for further teaching by the nurse?
Correct Answer: B
Rationale: Fever and swelling at the site are signs of infection and should be reported to the physician. Showers should be taken until the insertion site is healed. Prolonged sitting can result in thrombosis formation. Bruising at the insertion site is common and may take from 1 to 3 weeks to resolve.
