Which of the following dietary recommendations is the most appropriate to give a patient who has been diagnosed with CAD?

Correct Answer: B

Rationale: The most appropriate dietary recommendation for a patient diagnosed with Coronary Artery Disease (CAD) is option B: Decreased intake of sodium, animal, other fats, overall calories, and increase dietary fiber. This recommendation is based on evidence-based guidelines for managing CAD. Reducing sodium intake helps lower blood pressure and decrease the risk of heart disease. Limiting animal fats and overall calorie intake can help lower cholesterol levels and reduce the risk of atherosclerosis. Increasing dietary fiber can aid in improving cholesterol levels and promoting overall heart health. Option A is incorrect because a diet high in simple carbohydrates can lead to elevated blood sugar levels and contribute to weight gain, both of which are risk factors for CAD. Option C is not ideal because high-protein intake, limited dairy products, and specific restrictions on sodium, potassium, and phosphorus are not typically recommended as the primary dietary interventions for CAD. In an educational context, it is important for healthcare professionals to understand the relationship between diet and cardiovascular health to provide evidence-based recommendations to patients with CAD. Teaching patients about heart-healthy dietary habits can empower them to make positive lifestyle changes that support their heart health and overall well-being.

Correct Answer: C

Rationale: In this scenario, the correct answer is C) reduces the pressure on the puncture site. This is the appropriate action because the patient is experiencing symptoms of arterial insufficiency due to compression device-related complications. By reducing pressure on the puncture site, the nurse can restore circulation and prevent further ischemic damage to the hand. Option A is incorrect because calling the physician may cause a delay in addressing the immediate issue of compromised circulation. Option B, performing an Allen test, is not necessary at this point as the symptoms already indicate arterial insufficiency. Option D, using Doppler ultrasound, is not the most urgent intervention needed to address the acute ischemic symptoms in the patient's hand. Educationally, this question assesses the nurse's ability to recognize and respond to complications following a cardiac catheterization procedure. It reinforces the importance of prompt assessment and intervention in managing post-procedural complications to prevent potential complications like ischemia and tissue damage. It also highlights the critical thinking skills required in assessing and managing vascular access-related issues in cardiovascular care.

Correct Answer: B

Rationale: In hypertension, the most common cause of organ damage is related to atherosclerotic changes in vessels that supply the organs. This is the correct answer (B) because hypertension leads to increased pressure within the blood vessels, causing them to undergo structural changes like thickening and hardening of the arterial walls. These changes can lead to atherosclerosis, where plaques build up and narrow the blood vessels, reducing blood flow to organs and tissues. Option A is incorrect because while increased fluid pressure against organ tissue can contribute to damage, it is not the primary mechanism in hypertension-related organ damage. Option C is incorrect as erosion and thinning of blood vessels from constant pressure is not the main pathophysiological process seen in hypertension. Option D is also incorrect as increased hydrostatic pressure causing leakage of plasma into organ interstitial spaces is not the primary cause of organ damage in hypertension. From an educational perspective, understanding the link between hypertension and atherosclerosis is crucial for healthcare professionals to effectively manage and prevent complications in patients with high blood pressure. Knowing how hypertension impacts the vascular system and organ health is essential for providing comprehensive care and educating patients on risk factors and lifestyle modifications to mitigate these effects.

Correct Answer: B

Rationale: The correct answer is B) Fasting triglycerides. Elevated fasting triglycerides, along with elevated LDL cholesterol, are strongly associated with coronary artery disease (CAD). Triglycerides are a type of fat found in the blood that can contribute to the buildup of plaque in the arteries, leading to a higher risk of CAD. Option A) Apolipoproteins play a role in lipid metabolism but are not specifically associated with CAD risk like triglycerides. Option C) Total serum cholesterol includes both LDL and HDL cholesterol levels, so it is not specific enough to determine the risk of CAD. Option D) High-density lipoprotein (HDL) is known as "good" cholesterol and is actually associated with a lower risk of CAD, as it helps remove LDL cholesterol from the bloodstream. Educationally, understanding the role of different lipid profiles in cardiovascular health is crucial for healthcare professionals to assess and manage CAD risk in patients. By recognizing the significance of fasting triglycerides in conjunction with LDL levels, clinicians can make informed decisions regarding preventive measures and treatments to reduce the risk of CAD and its complications.

Correct Answer: C

Rationale: In the context of a myocardial infarction (MI), the correct answer is C) Use continuous cardiac monitoring. This is because the most common complication of MI is cardiac arrhythmias, such as ventricular tachycardia or ventricular fibrillation. Continuous cardiac monitoring allows for early detection of any abnormal heart rhythms, enabling prompt intervention and treatment to prevent further complications like sudden cardiac arrest. Option A) Measure hourly urine output is not directly related to the most common complication of MI. While monitoring urine output is important for assessing renal function and fluid balance, it is not the primary concern when dealing with complications of MI. Option B) Auscultate the chest for crackles is more indicative of heart failure or pulmonary edema, which can be a complication of MI but is not the most common one. While crackles may be present in some cases of MI, they are not specific to detecting arrhythmias, which are the primary concern. Option D) Take vital signs every 2 hours for the first 8 hours is a general monitoring practice but may not provide real-time information about cardiac rhythm abnormalities. Vital signs are important for overall assessment, but continuous cardiac monitoring is specifically designed to monitor the heart's electrical activity continuously, making it the most appropriate choice in this scenario. From an educational perspective, understanding the rationale behind the correct answer not only helps in answering exam questions correctly but also reinforces the importance of specific monitoring techniques in managing patients with MI. It emphasizes the critical role of continuous cardiac monitoring in early detection and intervention, ultimately improving patient outcomes and safety.
