The public health nurse is participating in a health fair and interviews a patient with a history of hypertension, who is currently smoking one pack of cigarettes per day. She denies any of the most common manifestations of CAD. Based on these data, the nurse would expect the focuses of CAD treatment most likely to be which of the following?
- A. Drug therapy and smoking cessation
- B. Diet and drug therapy
- C. Diet therapy only
- D. Diet therapy and smoking cessation
Correct Answer: D
Rationale: Due to the absence of symptoms, dietary therapy would likely be selected as the first-line treatment for possible CAD. Drug therapy would be determined based on a number of considerations and diagnostics findings, but would not be directly indicated. Smoking cessation is always indicated, regardless of the presence or absence of symptoms.

A nurse has taken on the care of a patient who had a coronary artery stent placed yesterday. When reviewing the patients daily medication administration record, the nurse should anticipate administering what drug?
- A. Ibuprofen
- B. Clopidogrel
- C. Dipyridamole
- D. Acetaminophen
Correct Answer: B
Rationale: Because of the risk of thrombus formation within the stent, the patient receives antiplatelet medications, usually aspirin and clopidogrel. Ibuprofen and acetaminophen are not antiplatelet drugs. Dipyridamole is not the drug of choice following stent placement.
You are writing a care plan for a patient who has been diagnosed with angina pectoris. The patient describes herself as being distressed and shocked by her new diagnosis. What nursing diagnosis is most clearly suggested by the womans statement?
- A. Spiritual distress related to change in health status
- B. Acute confusion related to prognosis for recovery
- C. Anxiety related to cardiac symptoms
- D. Deficient knowledge related to treatment of angina pectoris
Correct Answer: C
Rationale: Although further assessment is warranted, it is not unlikely that the patient is experiencing anxiety. In patients with CAD, this often relates to the threat of sudden death. There is no evidence of confusion (i.e., delirium or dementia) and there may or may not be a spiritual element to her concerns. Similarly, it is not clear that a lack of knowledge or information is the root of her anxiety.
The nurse is caring for a patient who has been diagnosed with an elevated cholesterol level. The nurse is aware that plaque on the inner lumen of arteries is composed chiefly of what?
- A. Lipids and fibrous tissue
- B. White blood cells
- C. Lipoproteins
- D. High-density cholesterol
Correct Answer: A
Rationale: As T-lymphocytes and monocytes infiltrate to ingest lipids on the arterial wall and then die, a fibrous tissue develops. This causes plaques to form on the inner lumen of arterial walls. These plaques do not consist of white cells, lipoproteins, or high-density cholesterol.
The nurse is caring for a patient who has undergone percutaneous transluminal coronary angioplasty (PTCA). What is the major indicator of success for this procedure?
- A. Increase in the size of the arterys lumen
- B. Decrease in arterial blood flow in relation to venous flow
- C. Increase in the patients resting heart rate
- D. Increase in the patients level of consciousness (LOC)
Correct Answer: A
Rationale: PTCA is used to open blocked coronary vessels and resolve ischemia. The procedure may result in beneficial changes to the patients LOC or heart rate, but these are not the overarching goals of PTCA. Increased arterial flow is the focus of the procedures.
A patient is recovering in the hospital from cardiac surgery. The nurse has identified the diagnosis of risk for ineffective airway clearance related to pulmonary secretions. What intervention best addresses this risk?
- A. Administration of bronchodilators by nebulizer
- B. Administration of inhaled corticosteroids by metered dose inhaler (MDI)
- C. Patients consistent performance of deep breathing and coughing exercises
- D. Patients active participation in the cardiac rehabilitation program
Correct Answer: C
Rationale: Clearance of pulmonary secretions is accomplished by frequent repositioning of the patient, suctioning, and chest physical therapy, as well as educating and encouraging the patient to breathe deeply and cough. Medications are not normally used to achieve this goal. Rehabilitation is important, but will not necessarily aid the mobilization of respiratory secretions.
