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: A

Rationale: The correct answer is A: Administer IV antibiotics. Administering IV antibiotics is crucial in treating pneumonia as it helps combat the underlying bacterial infection causing pneumonia. Prompt antibiotic therapy can prevent complications and improve patient outcomes. Administering pain medications (B) may help manage symptoms but does not address the root cause. Administering antiemetics (C) may help with nausea and vomiting but does not directly treat pneumonia. Option D is similar to the correct answer but lacks the specificity of IV antibiotics, which are often preferred for severe cases.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. This is the most important nursing intervention for a client with severe dehydration because IV fluids provide rapid rehydration and help restore electrolyte balance efficiently. Monitoring vital signs (choice B) is important but not as crucial as providing immediate fluid replacement. Providing oral rehydration (choice C) may not be effective for severe dehydration as the client may have difficulty absorbing fluids orally. Administering oxygen (choice D) is not directly related to treating dehydration, so it is not the most important intervention in this scenario.

Correct Answer: D

Rationale: The correct answer is D because palliative care aims to improve the quality of life for patients with serious illnesses like cancer. Severe pain and nausea (A) are common symptoms that palliative care helps manage. Uncontrolled symptoms despite treatment (B) indicate the need for specialized palliative care interventions. Psychosocial support needs (C) are also addressed in palliative care to address emotional and social aspects of the patient's well-being. Therefore, all of the above (D) are indicative of the need for palliative care as it focuses on holistic symptom management and support for the patient.
