A resident of a long-term care facility has complained to the nurse of chest pain. What aspect of the residents pain would be most suggestive of angina as the cause?
- A. The pain is worse when the resident inhales deeply
- B. The pain occurs immediately following physical exertion
- C. The pain is worse when the resident coughs
- D. The pain is most severe when the resident moves his upper body
Correct Answer: B
Rationale: Chest pain associated with angina is often precipitated by physical exertion. The other listed aspects of chest pain are more closely associated with noncardiac etiologies.

The nurse is relating the deficits in a patients synchronization of the atrial and ventricular events to his diagnosis. What are the physiologic characteristics of the nodal and Purkinje cells that provide this synchronization? Select all that apply.
- A. Loop connectivity
- B. Excitability
- C. Automaticity
- D. Conductivity
- E. Independence
Correct Answer: B,C,D
Rationale: Three physiologic characteristics of two types of specialized electrical cells, the nodal cells and the Purkinje cells, provide this synchronization: automaticity, or the ability to initiate an electrical impulse; excitability, or the ability to respond to an electrical impulse; and conductivity, the ability to transmit an electrical impulse from one cell to another. Loop connectivity is a distracter for this question. Independence of the cells has nothing to do with the synchronization described in the scenario.
The nurse is calculating a cardiac patients pulse pressure. If the patients blood pressure is 122/76 mm Hg, what is the patients pulse pressure?
- A. 46 mm Hg
- B. 99 mm Hg
- C. 198 mm Hg
- D. 76 mm Hg
Correct Answer: A
Rationale: Pulse pressure is the difference between the systolic and diastolic pressure. In this case, this value is 46 mm Hg (122 - 76 = 46).
The nurse is doing discharge teaching with a patient who has coronary artery disease. The patient asks why he has to take an aspirin every day if he doesnt have any pain. What would be the nurses best response?
- A. Taking an aspirin every day is an easy way to help restore the normal function of your heart
- B. An aspirin a day can help prevent some of the blockages that can cause chest pain or heart attacks
- C. Taking an aspirin every day is a simple way to make your blood penetrate your heart more freely
- D. An aspirin a day eventually helps your blood carry more oxygen that it would otherwise
Correct Answer: B
Rationale: An aspirin a day is a common nonprescription medication that improves outcomes in patients with CAD due to its antiplatelet action. It does not affect oxygen carrying capacity or perfusion. Aspirin does not restore cardiac function.
The critical care nurse is caring for a patient who has had an MI. The nurse should expect to assist with establishing what hemodynamic monitoring procedure to assess the patients left ventricular function?
- A. Central venous pressure (CVP) monitoring
- B. Pulmonary artery pressure monitoring (PAPM)
- C. Systemic arterial pressure monitoring (SAPM)
- D. Arterial blood gases (ABG)
Correct Answer: B
Rationale: PAPM is used to assess left ventricular function. CVP is used to assess right ventricular function; SAPM is used for continual assessment of BP. ABG are used to assess for acidic and alkalotic levels in the blood.
The physician has ordered a high-sensitivity C-reactive protein (hs-CRP) drawn on a patient. The results of this test will allow the nurse to evaluate the role of what process that is implicated in the development of atherosclerosis?
- A. Immunosuppression
- B. Inflammation
- C. Infection
- D. Hemostasis
Correct Answer: B
Rationale: High-sensitivity CRP is a protein produced by the liver in response to systemic inflammation. Inflammation is thought to play a role in the development and progression of atherosclerosis.
