Correct Answer: A

Rationale: The priority action by the nurse when a client receiving heparin therapy for deep venous thrombosis (DVT) presents with symptoms suggestive of a pulmonary embolism, such as severe chest pain and shortness of breath, is to assess the client's pulse, respirations, and blood pressure. These vital signs will provide crucial information about the client's current cardiovascular and respiratory status, which is essential for determining the severity of the condition and guiding immediate interventions. Assessing these vital signs will help the nurse quickly identify any signs of hemodynamic instability or respiratory distress, enabling prompt and appropriate treatment to be initiated. Once the assessment is done, further interventions such as oxygen therapy and notifying the healthcare provider can be implemented as needed.

Correct Answer: C

Rationale: - Activity C, where class members demonstrate a favorite nursing skill for the class, falls within the affective domain of Bloom's taxonomy. This activity involves showcasing a personal preference and emotional connection to a particular skill, demonstrating feelings and attitudes towards it.

Rationale: Arrhythmogenic right ventricular dysplasia (ARVD) is not a type of cardiomyopathy; it is a separate condition that affects the heart muscle. The other options, dilated cardiomyopathy, restrictive cardiomyopathy, and hypertrophic cardiomyopathy, are all types of cardiomyopathy that involve the heart muscle becoming weak, stiff, or abnormally thick. It is important for the nurse to clarify this distinction in order to provide accurate information to the client.

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.
