What is included in the correct technique for BP measurements?

Correct Answer: D

Rationale: In the context of measuring blood pressure, the correct technique is crucial for obtaining accurate readings. Option D, which states to take readings at least two times at least 1 minute apart, is the correct choice. This is because blood pressure can fluctuate due to various factors such as stress, activity, or time of day. Taking multiple readings helps to account for these fluctuations and provides a more reliable average value. Option A, which suggests always taking the BP in both arms, is incorrect because it is not necessary for routine blood pressure measurement. Typically, healthcare providers measure BP in one arm unless there is a specific medical reason to check both arms. Option B, positioning the patient supine for all readings, is also incorrect. While this position may be used in certain clinical scenarios, such as assessing orthostatic changes, it is not the standard position for routine blood pressure measurements. Option C, placing the cuff loosely around the upper arm, is incorrect as well. The cuff should be snug but not too tight to ensure an accurate reading. A loose cuff can lead to falsely low readings. Educationally, understanding the correct technique for blood pressure measurements is essential for healthcare providers, especially for those seeking certifications like the ANCC Cardiovascular Certification. Proper technique ensures accurate results, which are crucial for diagnosing and managing cardiovascular conditions. By following standardized procedures, healthcare professionals can provide optimal care for their patients.

Correct Answer: C

Rationale: In explaining to the patient that the internal mammary artery will be detached from the chest wall and attached to a coronary artery distal to the stenosis during CABG surgery (Option C), the nurse is providing accurate information about the procedure. This is the correct answer because using the internal mammary artery as a graft has shown better long-term patency rates compared to synthetic grafts or saphenous veins. Option A is incorrect because a synthetic graft is typically used to bypass the obstruction, not as a tube for blood flow. Option B is incorrect as resecting the coronary artery is not a standard practice in CABG surgery. Option D is incorrect because reversed segments of a saphenous artery are typically used as grafts, but not from the aorta. For educational context, it is important for nurses to understand the rationale behind using specific grafts in CABG surgery to provide accurate and clear information to patients. This knowledge helps in patient education, informed consent, and post-operative care management. Understanding the advantages and disadvantages of different graft options is crucial for optimal patient outcomes.

Correct Answer: A

Rationale: Unstable angina is a type of chest pain that occurs at rest due to reduced blood flow to the heart. The correct answer is A) Chest pain at rest. This is because unstable angina is characterized by chest pain that is unpredictable, occurs at rest, and can be a sign of an impending heart attack. Option B) Chest pain during exertion typically describes stable angina, where chest pain is triggered by physical activity or stress, but it is relieved by rest. Option C) Chest pain relieved by nitroglycerin is more indicative of stable angina, where nitroglycerin can alleviate chest pain associated with coronary artery disease. It is crucial for healthcare professionals, especially those specializing in cardiovascular care, to understand the differences between stable and unstable angina as the management and urgency of treatment differ significantly. Recognizing the symptoms of unstable angina promptly is vital for providing appropriate care and preventing adverse cardiac events.

Correct Answer: C

Rationale: The correct answer is C) Both A and B. Explanation: A Mantoux test, also known as a tuberculin skin test, involves the intradermal injection of purified protein derivative (PPD) tuberculin into the forearm. This injection is administered just beneath the skin's surface, which is why it is considered an intradermal injection. After the injection, healthcare providers measure the diameter of any induration, or raised, hardened area of skin at the injection site. The size of the induration is crucial in interpreting the results of the Mantoux test. Why the other options are wrong: A) Intradermal injection alone does not encompass the full process of the Mantoux test. The test involves both the intradermal injection and the subsequent measurement of any resulting induration. B) Induration measurement alone is not sufficient to describe the Mantoux test. The process involves both the injection and the measurement of induration to assess the body's immune response to the PPD tuberculin. Educational context: Understanding the Mantoux test is vital for healthcare professionals, especially those working in settings where tuberculosis screening is necessary. By knowing how the test is conducted and interpreted, healthcare providers can accurately assess individuals for potential exposure to tuberculosis and determine the need for further testing or treatment. This knowledge is crucial for ensuring the health and safety of both patients and healthcare workers.

Correct Answer: D

Rationale: The correct answer is D) She is wearing clean cotton socks with lamb's wool between her toes. This option indicates compliance with home health measures for peripheral vascular disease as it demonstrates appropriate foot care practices to prevent complications like pressure ulcers and infections. Clean cotton socks help maintain proper foot hygiene, while lamb's wool between the toes promotes moisture absorption and prevents skin breakdown. Option A is incorrect as using wide rubber bands instead of store-bought garters can constrict blood flow and worsen circulation issues in peripheral vascular disease. Option B is also incorrect as a dry sterile dressing on a foot where a corn was cut off could lead to infection if not properly managed. Option C is incorrect because using hot-water bottles to keep feet warm can increase the risk of burns and skin damage, especially for individuals with impaired sensation due to peripheral vascular disease. In an educational context, understanding the importance of proper foot care in peripheral vascular disease is crucial for preventing complications and promoting optimal outcomes. Educating patients on appropriate measures such as wearing clean socks and using lamb's wool can help them maintain foot health and reduce the risk of further vascular issues.
