The nurse is documenting assessment findings on a client with angina. Which term should the nurse use to describe chest pain that occurs at night and is unrelated to activity?

Correct Answer: B

Rationale: Prinzmetal angina, also known as variant angina or vasospastic angina, is characterized by chest pain that occurs at rest, often during the night or early morning, and is unrelated to activity or emotional stress. This type of angina is caused by transient coronary artery vasospasm, which leads to a temporary reduction in blood flow to the heart. Patients with Prinzmetal angina may have normal coronary arteries or minimal atherosclerosis. It differs from stable and unstable angina, which are typically triggered by physical or emotional stress. Nonanginal pain refers to chest discomfort that is not related to cardiac causes.

Correct Answer: B

Rationale: Smoking is a major risk factor for developing heart failure. African Americans are at a higher risk of heart failure compared to Caucasians. Additionally, being female and smoking further increase the risk. Smoking damages the blood vessels and heart, leading to various cardiovascular problems including heart failure. Therefore, the 50-year-old African American female who smokes is at the greatest risk of developing heart failure among the given options.

Correct Answer: D

Rationale: Tobacco use is a modifiable risk factor for hypertension. Smoking cigarettes can lead to an increase in blood pressure and heart rate, as well as damage to blood vessels, which can contribute to the development of hypertension. By quitting smoking or avoiding tobacco use, individuals can reduce their risk of developing hypertension and improve their overall cardiovascular health. On the other hand, factors such as age, ethnicity, and family history are non-modifiable risk factors for hypertension, meaning individuals cannot change them through lifestyle modifications.

Correct Answer: B

Rationale: The nursing diagnosis of Activity Intolerance is the most appropriate for a client with a cardiac dysrhythmia who reports being easily fatigued and having difficulty performing normal daily activities. Cardiac dysrhythmias can lead to decreased cardiac output, which can result in reduced oxygen delivery to the body's tissues, contributing to fatigue and weakness. Activity Intolerance is defined as the state in which an individual experiences or is at risk of experiencing insufficient physiological or psychological energy to endure or complete daily activities. This diagnosis is fitting for the client's inability to perform normal daily activities due to the cardiac dysrhythmia-induced fatigue and weakness. Addressing Activity Intolerance will involve collaborating with the client to set achievable activity goals and incorporating periods of rest to enhance tolerance to physical activity and improve overall function.

Correct Answer: D

Rationale: An Unna boot is a type of compression bandage that is impregnated with zinc oxide paste. This paste helps to provide a moist environment for the wound, which can promote healing and also has antimicrobial properties. The compression from the Unna boot helps to reduce swelling and improve circulation in the affected area, which is beneficial for treating stasis ulcers. By understanding that an Unna boot contains zinc oxide paste, the home care nurse can ensure proper application and effectiveness in promoting wound healing.
