You are working in the emergency department (ED) when a patient arrives, complaining of substernal and left arm discomfort that has been going on for about 3 hours. All of these baseline laboratory tests are drawn. Which one will be most useful in determining whether you should anticipate implementing the acute coronary syndrome (ACS) standard orders?

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Troponin. Troponin is the most specific and sensitive biomarker for myocardial injury, making it the gold standard for diagnosing acute coronary syndrome (ACS). Elevated troponin levels indicate damage to the heart muscle, which is a hallmark of ACS. This information is crucial for determining the need for immediate intervention and treatment in the emergency department. Creatine kinase-MB (Option A) is less specific to cardiac injury compared to troponin and can also be elevated in conditions like skeletal muscle damage, limiting its utility in diagnosing ACS. Myoglobin (Option C) is an early marker of muscle injury but lacks the specificity of troponin for cardiac muscle, leading to higher false-positive results. C-reactive protein (Option D) is a marker of inflammation and does not provide direct evidence of myocardial injury. Educationally, understanding the significance of troponin in the context of ACS is vital for healthcare professionals working in emergency settings. It underscores the importance of accurate and timely diagnostic tests in guiding patient management decisions, especially in high-stakes situations like suspected heart attacks. This knowledge equips healthcare providers with the necessary tools to deliver optimal care and improve patient outcomes in critical situations.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Greeting the client by name. This intervention is crucial in establishing a personal connection with the client, which helps to reduce the feeling of being cared for by strangers. When a healthcare provider addresses a client by name, it conveys a sense of respect, empathy, and individualized care. This simple gesture can help build trust and rapport between the client and the healthcare team, ultimately improving the client's overall experience and outcomes. Option A) Allowing for rest periods is important for client comfort, but it does not directly address the issue of feeling cared for by strangers. Option C) Increasing bright lights may actually increase the client's discomfort and anxiety, rather than alleviating the feeling of being cared for by strangers. Option D) Asking the client to paraphrase information may be a good communication strategy, but it does not specifically target the emotional aspect of feeling cared for by strangers. In an educational context, it is important for healthcare providers to understand the significance of building a therapeutic relationship with clients, especially in vulnerable situations such as diagnostic procedures. Simple gestures like greeting the client by name can have a profound impact on the client's perception of care and can contribute to a more positive healthcare experience. By emphasizing the importance of person-centered care and communication skills, healthcare providers can enhance client satisfaction and outcomes.

Correct Answer: B

Rationale: In the context of cardiovascular health, the correct answer is B) To prevent thrombophlebitis. Thrombophlebitis is the inflammation of a vein with a blood clot formation, commonly occurring in the legs due to prolonged immobility. Encouraging a client to move frequently helps promote blood circulation, preventing the formation of blood clots which can lead to thrombophlebitis. Option A) To keep the client from noticing pain is incorrect as the primary reason for encouraging movement is not pain management but rather prevention of a serious complication like thrombophlebitis. Option C) To provide activity to keep the client from being bored is incorrect as the focus is on the physiological benefits of movement in preventing health complications, not simply to alleviate boredom. Option D) To prevent stasis ulcers is incorrect as stasis ulcers are more related to decreased blood flow and tissue damage rather than clot formation due to immobility. In an educational context, it is important for nurses and healthcare professionals to understand the rationale behind encouraging movement in clients, especially those at risk for cardiovascular complications. By promoting frequent movement, healthcare providers can actively contribute to preventing potentially life-threatening conditions like thrombophlebitis, highlighting the crucial role of nursing interventions in maintaining patient health and well-being.

Correct Answer: A

Rationale: The correct answer is A) Arteriosclerosis. Arteriosclerosis is a condition in which calcium causes the arteries to lose elasticity, leading to stiffening of the arterial walls. This stiffness impairs the ability of the arteries to stretch and accommodate the surge of blood flow from the contracting left ventricle during systole. Option B) Coronary occlusion refers to the blockage of a coronary artery, leading to a lack of blood supply to the heart muscle. This is not the appropriate diagnosis for the condition described in the question. Option C) Ischemia refers to inadequate blood supply to an organ, usually due to a constriction or obstruction of blood vessels, leading to tissue damage. While ischemia can be a consequence of arteriosclerosis, it is not the primary diagnosis for this specific scenario. Option D) Atherosclerosis is the buildup of fats, cholesterol, and other substances in and on the artery walls, leading to the formation of plaques that can restrict blood flow. While atherosclerosis is related to arteriosclerosis, it specifically involves plaque formation rather than the loss of arterial elasticity. Educationally, understanding the distinction between these terms is crucial for healthcare professionals to accurately diagnose and manage cardiovascular conditions in elderly patients. Recognizing the unique characteristics of each condition is essential for providing appropriate treatment and preventative care to improve patient outcomes.

Correct Answer: A

Rationale: The correct answer is A) Postural hypotension. Postural hypotension, also known as orthostatic hypotension, is characterized by a drop in blood pressure when a person stands up from sitting or lying down. In this case, the client's symptoms of dizziness upon standing, along with nosebleeds and blurred vision, are indicative of decreased blood flow to the brain upon changing positions. These symptoms align with the classic presentation of postural hypotension in older adults. Option B) White-coat hypertension is incorrect in this scenario as the client's symptoms are not consistent with the phenomenon of elevated blood pressure readings in a clinical setting due to anxiety. Option C) Postural hypertension is not a recognized medical condition. The term typically used is postural hypotension for a drop in blood pressure upon standing. Option D) White-coat hypotension is also an inaccurate choice as it does not match the symptoms described by the client. White-coat hypotension refers to elevated blood pressure readings in a clinical setting due to stress or anxiety. Educationally, understanding the manifestations of postural hypotension is crucial for nurses in assessing and managing older adults who may be at higher risk for this condition. Proper assessment, monitoring, and interventions are essential to prevent falls and other complications related to postural changes in blood pressure.
