The provider requests the nurse to start an infusion of an inotropic agent on a client. How should the nurse explain the action of these drugs to the client and spouse?

Correct Answer: C

Rationale: The correct answer is C: It increases the force of the heart's contractions. Inotropic agents are medications that enhance the strength of the heart's contractions, improving cardiac output. This explanation is accurate because inotropic agents work by increasing the contractility of the heart muscle, leading to stronger contractions and improved pumping ability. Explanation for why the other choices are incorrect: A: It constricts vessels, improving blood flow - This is incorrect because inotropic agents primarily affect the heart's contractility, not vascular constriction. B: It dilates vessels, which lessens the work of the heart - This is incorrect because inotropic agents do not primarily dilate vessels; their main action is on the heart's contractility. D: It slows the heart rate down for better filling - This is incorrect because inotropic agents do not slow down the heart rate; they increase the force of contractions. In summary, choice C is correct as inotropic agents increase the force of

Correct Answer: A

Rationale: The correct action is to assess the client's blood pressure and level of consciousness. This is crucial in a client with an inferior wall MI to monitor for potential complications like cardiogenic shock. Assessing these vital signs can provide immediate information on the client's hemodynamic stability. Calling the health care provider or Rapid Response Team may be necessary based on assessment findings. Obtaining a permit for a temporary pacemaker insertion and preparing to administer antidysrhythmic medication are not the most immediate priorities and may not address the client's current needs.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Hypertension is a modifiable risk factor as it can be controlled through lifestyle changes and medication. 2. Age is a non-modifiable risk factor, as it naturally increases the risk of coronary artery disease. 3. Obesity is a modifiable risk factor, as weight management through diet and exercise can reduce the risk. 4. Smoking is a modifiable risk factor, as quitting smoking can significantly reduce the risk. Summary: B is correct as it is a modifiable risk factor that can be actively managed. A, C, and D are incorrect as age is non-modifiable and obesity and smoking are modifiable but were not selected as correct options.

Correct Answer: A

Rationale: The correct answer is A: Age. Age is a non-modifiable risk factor for coronary artery disease, meaning it cannot be changed or controlled. Hypertension, obesity, and smoking are modifiable risk factors as they can be managed through lifestyle changes or medical interventions. By controlling blood pressure, maintaining a healthy weight, and quitting smoking, individuals can reduce their risk of developing coronary artery disease. Age, however, is a natural process that cannot be altered. Therefore, focusing on managing modifiable risk factors is crucial in preventing coronary artery disease.

Correct Answer: C

Rationale: The correct answer is C because the pain of a myocardial infarction (MI) typically lasts longer than 15 minutes, unlike stable angina which lasts for a shorter duration. MI pain is usually described as intense, crushing, and prolonged, whereas stable angina pain is often triggered by exertion and relieved by rest or medication like nitroglycerin. Choices A, B, and D are incorrect because shortness of breath, feelings of fear or anxiety, and lack of relief from nitroglycerin are not definitive differentiating factors between MI and stable angina.
