Cardio - Chapter 8 Questions

The home health nurse caring for a patient with infective endocarditis overhears the patient making a dental appointment for an extraction next month. Which question is most important for the nurse to ask? a. "Do you have a toothache?" b. "Have you contacted your physician about your dental appointment?" c. "Is your dentist board certified?" d. "Do you think you should wait that long for your tooth extraction?'

b. "Have you contacted your physician about your dental appointment?" Patients with endocarditis are put on a protocol of prophylactic antibiotics for any invasive procedure. The dentist and physician should be contacted before the extraction.

The nurse caring for a patient recovering from a myocardial infarct who is on remote telemetry recognizes the need for added instruction when the patient says: a. "I can ambulate in the hallway with this gadget on." b. "I always take off the telemetry device when I shower." c. "My EKG is being watched by one of the nurses in CCU on the home unit." d. "I am able to sleep just fine with this device on."

b. "I always take off the telemetry device when I shower." Remote telemetry allows the patient to be on a separate unit, but be monitored in a central location. The patients can be ambulatory and can sleep with the monitor on. They should not remove the monitor to shower.

Which statement would lead the nurse to offer more instruction about taking warfarin (Coumadin)? a. "I eat a banana every morning with breakfast." b. "I try to eat more green leafy vegetables, especially broccoli, spinach, and kale." c. "I try to eat a well-balanced, low-fat diet." d. "I don't drink alcohol or caffeine."

b. "I try to eat more green leafy vegetables, especially broccoli, spinach, and kale." Avoid marked changes in eating habits, such as dramatically increasing foods high in vitamin K (e.g., broccoli, spinach, kale, greens). Limit alcohol intake to small amounts.

The elderly patient with angina pectoris says she is unsure how she should take nitroglycerin when she has an attack. The nurse's most helpful response would be: a. "Continue to take nitroglycerin sublingually at 5-minute intervals until the pain is relieved." b. "If the pain is not relieved after three doses of nitroglycerin at 5-minute intervals, call your physician and come to the hospital." c. "When nitroglycerin is not relieving the pain, lie down and rest." d. "Use oxygen at home to relieve pain when nitroglycerin is not successful."

b. "If the pain is not relieved after three doses of nitroglycerin at 5-minute intervals, call your physician and come to the hospital." Administer prescribed nitroglycerin. Repeat every 5 minutes, three times. If pain is unrelieved, notify the physician. Nitroglycerin administered sublingually usually relieves angina symptoms but does not relieve the pain from an MI. Administering nitroglycerin more than three times will probably not relieve the pain.

The nurse assesses pitting edema that can be depressed approximately inch and refills in 15 seconds. The nurse would document this assessment as: a. +1 edema. b. +2 edema. c. +3 edema. d. +4 edema.

b. +2 edema. A +2 edema can be documented if the skin can be depressed inch and respond within 15 seconds.

b. 2 and 3. The desired INR for the monitoring of anticoagulant therapy is between 2 and 3.

What should a person with unstable angina avoid? a. Walking outside b. Eating red meat c. Swimming in warm pool d. Shoveling snow

d. Shoveling snow The person with angina should avoid exposure to cold, heavy exercise, eating heavy meals, and emotional stress.

The patient with congestive heart failure who is on a diuretic drug shows a weight loss of 6.6 lb. The nurse is aware that the patient has lost ______ L of fluid.

3 A liter of fluid equals 2.2 lb. A loss of 6.6 lb would mean the loss of 3 L of fluid.

While obtaining a nursing history from her, the nurse recognizes that the increased incidence of cardiomyopathy in young adults who have minimal risk factors for cardiovascular disease is related to which factor(s)? a. Cocaine use b. Viral infections c. Vitamin B1 deficiencies d. Pregnancy

a. Cocaine use Cardiomyopathy caused by cocaine abuse is seen more frequently than ever before. Cocaine also causes high circulating levels of catecholamines, which may further damage myocardial cells, leading to ischemic or dilated cardiomyopathy.

What is the nurse assessing for when she flexes the patient's right leg and dorsiflexes the foot? a. Pain, which would be a positive Homans sign b. Muscular spasm, which would be a sign of hypocalcemia c. Rigidity, which would be a sign of ankylosis d. Crepitus, which would be a sign of a joint disorder
