Which lifestyle modification is recommended for individuals with heart failure?

Correct Answer: C

Rationale: The correct answer is C: Regular physical activity. Physical activity is recommended for individuals with heart failure as it can help improve cardiovascular health, strengthen the heart muscle, and enhance overall well-being. Exercise can also help manage symptoms of heart failure and improve quality of life. The other choices are incorrect: A: Sedentary lifestyle can worsen heart failure symptoms and lead to deconditioning. B: Smoking is harmful for heart health and can exacerbate heart failure. D: Excessive alcohol consumption can weaken the heart muscle and contribute to heart failure complications.

Correct Answer: C

Rationale: Rationale: 1. Amantadine is an antiviral medication effective against type A influenza virus. 2. By taking it within 48 hours of exposure, it can lessen flu symptoms by inhibiting viral replication. 3. It does not prevent pneumonia or avian flu specifically. 4. It is not used for reducing bronchitis irritation. Summary: Amantadine is specifically used to reduce the severity of type A flu symptoms when taken within 48 hours of exposure. It is not for prevention of viral pneumonia, avian flu, or bronchitis irritation.

Correct Answer: B

Rationale: Step 1: Carbonic anhydrase catalyzes the reaction between carbon dioxide (CO2) and water (H2O). Step 2: This reaction forms carbonic acid (H2CO3). Step 3: Carbonic acid then dissociates into bicarbonate ion (HCO3-) and hydrogen ion (H+). Step 4: Therefore, the ion formed as a result of the action of carbonic anhydrase on CO2 and H2O is the bicarbonate ion (HCO3-). Summary: - Choice A (Sodium ion) is incorrect as it is not involved in the reaction with carbonic anhydrase. - Choice C (Hydroxide ion) is incorrect as it is not a product of the reaction but rather a different compound. - Choice D (Potassium ion) is incorrect as it is not related to the reaction between carbon dioxide and water.

Correct Answer: D

Rationale: Step 1: Consumption of a heavy meal can lead to increased blood flow to the digestive system, causing a temporary reduction in blood flow to the heart muscle. Step 2: This reduction can trigger angina symptoms in individuals with chronic stable angina. Step 3: Emphasizing this to the client helps in understanding potential triggers to manage their condition effectively. Step 4: Rest (A) is usually recommended to relieve angina, sudden change in position (B) is not a common trigger, and severe depression (C) can exacerbate angina but is not a direct precipitating factor like heavy meals.

Correct Answer: D

Rationale: The correct answer is D, respiratory acidosis without compensation. The low pH and high PCO2 levels indicate respiratory acidosis. HCO3 is within normal range, suggesting no metabolic compensation. This is not metabolic acidosis as the HCO3 level is not elevated. Not partial compensation as the HCO3 level is not compensating for the respiratory acidosis.
