1. Which artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart?
- A. Left anterior descending artery
- B. Left circumflex artery
- C. Posterior descending artery
- D. Aortic artery
Correct answer: A
Rationale: The correct answer is the Left anterior descending artery. This artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart. The Left circumflex artery (choice B) supplies the lateral and posterior walls of the left ventricle, the posterior descending artery (choice C) supplies the inferior part of the heart, and the aortic artery (choice D) is not a specific coronary artery.
2. A client is starting therapy with docetaxel. Which of the following findings should the nurse instruct the client to report?
- A. Flushing
- B. Dyspnea
- C. Hyperglycemia
- D. Tinnitus
Correct answer: B
Rationale: The correct answer is B: Dyspnea. The nurse should instruct the client to report dyspnea because it can indicate pulmonary toxicity, a serious adverse effect of docetaxel. Dyspnea may be a sign of a potentially life-threatening condition that the healthcare provider needs to address promptly. Flushing (Choice A) is not typically associated with docetaxel therapy. Hyperglycemia (Choice C) is also not a common side effect of docetaxel. Tinnitus (Choice D) is not a usual finding with docetaxel and is not a priority over potential pulmonary toxicity indicated by dyspnea.
3. When educating a client with a new prescription for Amlodipine, which instruction should the nurse provide?
- A. Increase your intake of dairy products.
- B. Avoid driving until you see how the medication affects you.
- C. Stop taking the medication if you develop a dry cough.
- D. Take the medication at bedtime.
Correct answer: B
Rationale: The correct answer is to advise the client to avoid driving until they understand the medication's effects. Amlodipine can cause dizziness, making it unsafe to drive until the client knows how the medication affects them. This instruction promotes client safety and prevents potential accidents due to medication side effects.
4. Which best describes the concept of health promotion?
- A. Focusing on treating illness
- B. Encouraging healthy behaviors
- C. Ensuring access to care
- D. Focusing on disease prevention
Correct answer: B
Rationale: The correct answer is B: 'Encouraging healthy behaviors.' Health promotion focuses on empowering individuals and communities to take control of their health by promoting healthy behaviors and lifestyles. This approach involves education, creating supportive environments, and advocating for policies that enhance well-being. It goes beyond simply treating illness or preventing diseases, emphasizing a proactive and holistic approach to achieving and maintaining good health.
5. Theresa, a mother with a 2-year-old daughter, asks, 'At what age can I start taking my daughter's blood pressure as a routine procedure, since hypertension is common in our family?' What would your answer be?
- A. At 2 years old, you may
- B. As early as 1 year old
- C. When she's 3 years old
- D. When she's 6 years old
Correct answer: D: When she's 6 years old
Rationale: Regular blood pressure checks generally start from age 3, but in the case of a family history of hypertension, they should start when the child is around 6 years old. This is because the readings will be more reliable and indicative of the child's health condition at this age. The other options are incorrect because they suggest earlier ages for routine blood pressure checks. While blood pressure can be measured at any age, it is not typically included as part of a routine health check-up for very young children unless there are specific health concerns.
