Correct Answer: B

Rationale: Correct Answer: B Rationale: Limiting alcohol intake reduces blood pressure. Reducing sodium intake also helps manage hypertension. Alcohol can increase blood pressure, while sodium can lead to fluid retention. The patient's statement shows understanding of the importance of both factors in managing hypertension. Other Choices: A: Increasing sodium intake worsens fluid retention and hypertension. C: Processed foods are often high in sodium and unhealthy fats, worsening hypertension. D: Reducing exercise can lead to weight gain and increased blood pressure, contrary to managing hypertension.

Correct Answer: B

Rationale: The correct answer is B: Provide a source of fast-acting carbohydrate. In hypoglycemia, the priority is to raise blood glucose levels quickly to prevent complications like seizures or loss of consciousness. Fast-acting carbs like juice or glucose tablets are the first-line treatment. Administering insulin (choice A) would lower blood sugar further. Administering an oral hypoglycemic agent (choice C) takes time to work and is not suitable for emergencies. Monitoring blood pressure (choice D) is important but not the priority in this situation.

Correct Answer: C

Rationale: The correct answer is C because using the inhaler every time the patient feels short of breath, even without a flare-up, is not the recommended practice for managing COPD. Inhalers should be used as prescribed by the healthcare provider or only during exacerbations. Here's the rationale: 1. Using the inhaler excessively can lead to overuse of medication and potential side effects. 2. It is important for patients to differentiate between regular management and acute exacerbations. 3. Monitoring oxygen levels (choice D) is essential for COPD management. 4. Quitting smoking (choice A) and deep breathing exercises (choice B) are positive self-management strategies for COPD.

Correct Answer: A

Rationale: The correct answer is A: Fever. Fever is an early indicator of infection as it is the body's natural response to fighting off pathogens. When the body detects an infection, it raises its temperature to create an inhospitable environment for the pathogens. Pain at the surgical site (B) is common post-operatively but may not necessarily indicate infection. Redness at the incision site (C) can be a sign of inflammation but is not specific to infection. Increased heart rate (D) can occur due to various reasons post-operatively, not just infection. Fever is a systemic response and a more reliable early indicator of infection in this context.

Correct Answer: A

Rationale: Correct Answer: A (Iron, folic acid, and B12) Rationale: 1. Iron: Renal failure patients often have anemia due to decreased erythropoietin production. 2. Folic acid and B12: Important for red blood cell production and maturation. 3. Corrects underlying causes of anemia in renal failure patients. Summary: B: Increasing protein doesn't directly address anemia in renal failure. C: Vitamin D and calcium are not primary treatments for anemia in renal failure. D: Calcium and folic acid alone do not address the specific deficiencies seen in renal failure anemia.
