Which of the following diets does the nurse recommend for clients with hypertension under the physician's guidance?

Correct Answer: D

Rationale: The correct answer is D) The DASH diet. The Dietary Approaches to Stop Hypertension (DASH) diet is specifically designed to help lower blood pressure in individuals with hypertension. It emphasizes consuming fruits, vegetables, whole grains, lean proteins, and low-fat dairy products while limiting intake of saturated fats, cholesterol, and refined sugars. This diet is rich in nutrients like potassium, calcium, and magnesium, which have been shown to have a positive impact on blood pressure levels. Option A) The food guide pyramid is a general guideline for a healthy diet but does not provide the specific focus on hypertension management that the DASH diet does. Option B) The step one diet is a low-cholesterol diet primarily used for managing high cholesterol levels, not hypertension. Option C) The South Beach diet is a popular weight-loss diet that focuses on consuming good fats and good carbs but does not have the same evidence-based recommendations for managing hypertension as the DASH diet. In an educational context, it is crucial for nurses to understand the importance of dietary recommendations in managing chronic conditions like hypertension. By recommending the appropriate diet, nurses can support their patients in improving their health outcomes and reducing the risks associated with uncontrolled hypertension. Educating patients on the benefits of following a DASH diet can empower them to make healthier choices and take an active role in managing their condition.

Correct Answer: B

Rationale: In the given scenario, the correct answer is B) Associated with CHF. An S3 heart sound is commonly associated with congestive heart failure (CHF). This sound occurs due to rapid ventricular filling during the early diastole when the blood is entering the ventricles. In patients with CHF, the heart is often enlarged and weakened, leading to this abnormal heart sound. Option A) A normal finding is incorrect because an S3 heart sound is not typically heard in a healthy heart. Option C) Thrombophlebitis and Option D) Peripheral artery disease are unrelated to the presence of an S3 heart sound and are not typical causes. Educationally, understanding cardiac sounds is crucial for nurses and healthcare professionals in assessing and managing cardiovascular conditions. Recognizing an S3 heart sound can prompt further diagnostic tests and interventions for CHF. It is essential to differentiate between normal and abnormal heart sounds to provide optimal patient care and ensure timely interventions for cardiac conditions.

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: D

Rationale: The correct answer is D) Maintain NPO status until gag reflex has returned. Following a transesophageal echocardiogram (TEE), the patient is usually under sedation and their gag reflex may be diminished. This places the patient at risk for aspiration if they were to consume food or fluids. Aspiration can lead to serious complications such as pneumonia or airway obstruction. Monitoring the ECG (option A) and pulse oximetry (option B) are important assessments, but maintaining NPO status takes precedence due to the risk of aspiration in this immediate post-procedure period. Assessing vital signs (option C) is also important, but ensuring the patient's safety by preventing aspiration is the priority immediately following a TEE. In an educational context, this question highlights the importance of understanding post-procedure care and the potential risks associated with specific procedures. It reinforces the need for critical thinking and prioritization of nursing interventions based on patient safety and potential complications.

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.
