Correct Answer: B

Rationale: The correct answer is B: obtaining daily weights at the same time. This is crucial in monitoring fluid retention, a common issue in heart failure patients. Daily weights help detect early signs of fluid buildup. Option A is incorrect as physical activity is important for heart failure patients. Option C is incorrect as walking 2 miles daily may be too strenuous for some heart failure patients. Option D is incorrect as a high fiber diet is beneficial, but monitoring fluid retention is more critical in this case.

Correct Answer: C

Rationale: Upon arrival, checking the lungs for equal breath sounds bilaterally is the first action. This is crucial to assess airway patency and breathing effectiveness in a patient with a history of diving accident and intubation. Ensuring proper oxygenation takes precedence over other actions. Taking vital signs, inserting an IV line, and performing a neurologic check can wait until airway and breathing are adequately assessed.

Correct Answer: C

Rationale: The correct answer is C because morphine sulfate is given to a patient with pulmonary edema to reduce anxiety (i) and to reduce preload and afterload (v). Morphine sulfate does not increase blood pressure (ii), relieve chest pain (iii), or strengthen heart contractions (iv) in the context of pulmonary edema. Choice A is incorrect because it includes increasing BP, which is not a reason for giving morphine sulfate in this case. Choice B is incorrect because it includes strengthening heart contractions, which is not a reason for administering morphine sulfate. Choice D is incorrect because it includes relieving chest pain, which is not a primary purpose of giving morphine sulfate to a patient with pulmonary edema.

Correct Answer: A

Rationale: The correct answer is A: Antiemetic. Chemotherapy commonly causes nausea and vomiting as adverse effects. Antiemetics are medications specifically designed to prevent or alleviate nausea and vomiting. Administering an antiemetic helps to manage these side effects and improve the patient's comfort and compliance with treatment. Antibiotics (choice B) are used to treat bacterial infections and are not directly related to combating chemotherapy side effects. Antimetabolites (choice C) are a type of chemotherapy drug, not used to combat its side effects. Anticoagulants (choice D) are used to prevent blood clots and are not indicated for managing chemotherapy-related nausea and vomiting.

Correct Answer: A

Rationale: Step 1: Level of consciousness is the most reliable index of cerebral state because it directly reflects the functioning of the brain. Changes in consciousness can indicate alterations in cerebral perfusion and potential increases in intracranial pressure. Step 2: Unilateral papillary dilatation may suggest an increase in intracranial pressure, but it is not as reliable as level of consciousness in assessing overall cerebral state. Step 3: Increased systolic blood pressure can occur due to various reasons and may not specifically indicate changes in intracranial pressure. Step 4: Decreased pulse pressure may be related to factors such as hypovolemia or cardiac conditions, but it is not a direct indicator of cerebral state or intracranial pressure.
