Correct Answer: C

Rationale: Rationale: C: Reinforce the dressing is the correct intervention for serosanguineous drainage after cholecystectomy. This helps maintain a clean and dry wound environment, promotes healing, and prevents infection. Changing the dressing (B) may disrupt the wound healing process. Notifying the physician (A) is important but not the immediate intervention. Applying an abdominal binder (D) is not indicated for managing serosanguineous drainage.

Correct Answer: A

Rationale: The correct answer is A: Increasing physical activity and reducing salt intake. Firstly, increasing physical activity helps lower blood pressure by improving heart health and circulation. Secondly, reducing salt intake helps decrease fluid retention and lower blood pressure. The other choices are incorrect because B: Increasing alcohol consumption can raise blood pressure, C: Decreasing physical activity is counterproductive, and D: Increasing sodium intake can lead to higher blood pressure due to fluid retention. Prioritizing physical activity and reducing salt intake are evidence-based lifestyle changes to manage hypertension effectively.

Correct Answer: D

Rationale: The correct answer is D: all of the above. Alcohol use can impair judgment leading to risky sexual behaviors. Certain sexual practices like unprotected sex or having multiple partners increase STD risk. Oral contraception does not protect against STDs. Therefore, all factors (A, B, C) collectively increase the risk of STDs.

Correct Answer: A

Rationale: The correct answer is A because it helps differentiate between orthopnea (difficulty breathing when lying down) and paroxysmal nocturnal dyspnea (sudden awakening due to difficulty breathing). By asking about worsening symptoms when lying down, the nurse can assess if the patient has orthopnea, a classic symptom of heart failure. Choices B, C, and D are incorrect because they do not specifically target the nighttime breathing difficulty associated with heart failure.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. Antibiotics are crucial in treating pneumonia caused by bacteria. They help to kill the bacteria causing the infection and prevent its spread. Administering fluids (B) is important for hydration but not the most crucial intervention. Monitoring temperature (C) is important but does not treat the root cause. Administering vaccines (D) may prevent certain types of pneumonia but is not the immediate intervention for an existing infection. Administering antibiotics promptly is vital to effectively treat pneumonia and prevent complications.
