A patient who is recovering from a myocardial infarction may benefit from meditation because this technique:

Correct Answer: A

Rationale: The correct answer is A) decreases sympathetic nervous system activity. Meditation has been shown to have a calming effect on the body by reducing the activity of the sympathetic nervous system, which is responsible for the body's "fight or flight" response. This is particularly beneficial for patients recovering from a myocardial infarction (heart attack) as it helps lower heart rate, blood pressure, and overall stress levels, promoting a more stable cardiovascular system. Option B) decreases vasodilation is incorrect because meditation actually promotes vasodilation, leading to improved blood flow and decreased workload on the heart. Option C) increases the release of catecholamines is incorrect because catecholamines are stress hormones that are typically reduced with meditation, not increased. Elevated catecholamines can exacerbate cardiovascular issues. Option D) increases sympathetic nervous system activity is incorrect as meditation is known to have the opposite effect by decreasing sympathetic nervous system activity, promoting a sense of relaxation and reducing stress. Educationally, understanding the physiological effects of meditation on the body can empower healthcare professionals to recommend holistic approaches to managing cardiovascular health and overall well-being for patients. It emphasizes the importance of incorporating mind-body techniques as complementary strategies in cardiac rehabilitation programs to support patients in their recovery journey.

Correct Answer: C

Rationale: A hypertensive emergency is a severe increase in blood pressure that can lead to organ damage. Option C, a sudden rise in BP accompanied by neurologic impairment, is indicative of a hypertensive emergency because it highlights the acute and severe nature of the condition that requires immediate intervention to prevent further complications such as stroke, renal failure, or myocardial infarction. Option A is incorrect because while symptoms of a stroke with elevated BP can be serious, it does not necessarily indicate a hypertensive emergency where immediate treatment is crucial. Option B describes high blood pressure levels but lacks the emphasis on the acute onset and potential organ damage seen in a hypertensive emergency. Option D describes a severe elevation of BP over days or weeks, which is more characteristic of hypertensive urgency rather than emergency. Educationally, understanding the distinction between hypertensive emergencies and urgencies is crucial for healthcare providers to appropriately triage and manage patients presenting with severe hypertension. Recognizing the signs and symptoms of a hypertensive emergency can lead to prompt intervention and prevent serious complications, underscoring the importance of clinical acumen in managing cardiovascular emergencies.

Correct Answer: B

Rationale: The correct answer is B) Captopril (Capoten). In this scenario, the patient's ejection fraction of 38% indicates reduced cardiac function and increased risk for a cardiac event. Captopril is an ACE inhibitor that helps in vasodilation, reducing afterload, and decreasing ventricular remodeling. By dilating blood vessels, captopril reduces the workload on the heart, improves cardiac output, and helps in remodeling of the ventricles. Option A) Clopidogrel (Plavix) is an antiplatelet medication and would not directly address vasodilation or ventricular remodeling in this case. Option C) Diltiazem (Cardizem) is a calcium channel blocker that primarily affects the heart's contraction and may not be as effective in reducing ventricular remodeling. Option D) Metoprolol (Lopressor) is a beta-blocker that can help in reducing heart rate and blood pressure, but it may not be the first choice for vasodilation and reducing ventricular remodeling in this specific scenario. Educationally, understanding the rationale behind selecting specific medications based on a patient's condition is crucial for nurses and healthcare providers. It is essential to comprehend the pharmacological actions of medications and their impact on the cardiovascular system to provide safe and effective care for patients with cardiac conditions. By knowing the mechanism of action of medications like Captopril in this case, healthcare professionals can make informed decisions to optimize patient outcomes and reduce the risk of cardiac events.

Correct Answer: A

Rationale: In this scenario, the correct answer is option A: Oozing of blood from the IV site. When a patient with a STEMI is receiving reteplase, a thrombolytic medication, one of the complications to watch out for is bleeding due to its anticoagulant effects. Oozing from the IV site indicates that the patient may be experiencing excessive bleeding, which can lead to serious complications such as hemorrhage. Option B, a BP of 102/60 mm Hg with an HR of 78 bpm, is within normal range and not a concerning finding in this context. Option C, a decrease in the responsiveness of the patient, could be a sign of various issues but is not specifically related to reteplase administration. Option D, the presence of intermittent accelerated idioventricular dysrhythmias, could be a concern but is not the most immediate concern when a patient is being treated with reteplase, as bleeding complications take precedence. Educationally, it is crucial for nurses to understand the potential side effects and complications of medications used in the treatment of STEMI. Monitoring for adverse effects, such as bleeding, is essential to ensure patient safety and well-being. Nurses must be vigilant in assessing and managing these potential complications to provide effective and safe care to patients undergoing thrombolytic therapy.

Correct Answer: D

Rationale: In the nursing management of Acute Myocardial Infarction (AMI), it is crucial to address various aspects to ensure optimal patient outcomes. Option A, monitoring vital signs, is essential in the early detection of any hemodynamic instability or complications such as arrhythmias or hypotension that may arise post-AMI. This allows for prompt intervention and prevents further damage to the heart. Option B, administering medications, is vital in managing AMI. Medications like antiplatelets, anticoagulants, beta-blockers, and pain relief medications play a significant role in reducing myocardial damage, preventing clot formation, managing pain, and stabilizing the patient. Option C, providing emotional support, is equally important in the nursing management of AMI. Patients experiencing an AMI are often scared, anxious, and may feel overwhelmed. Emotional support from the nursing staff can help alleviate these feelings, improve patient satisfaction, and positively impact their overall recovery process. Option D, "All of the above," is the correct answer because all the options are integral components of comprehensive nursing care for a patient with AMI. Monitoring vital signs ensures early detection of complications, administering medications aids in managing the condition, and providing emotional support addresses the holistic needs of the patient during this critical time. In an educational context, understanding the nursing management of AMI is crucial for nursing students and healthcare professionals working in cardiovascular care. By mastering these principles, nurses can provide safe, effective, and compassionate care to patients experiencing an AMI, ultimately improving patient outcomes and satisfaction.
