Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. Anticoagulants are the primary treatment for DVT as they prevent blood clots from getting bigger and reduce the risk of new clots forming. This helps prevent complications like pulmonary embolism. Elevating the leg and applying compression (option B) can help with symptoms but do not address the underlying cause. Providing anticoagulant therapy (option C) is similar to the correct answer but lacks specificity. Applying compression stockings (option D) can help prevent complications but do not treat the existing clot.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. The first priority in caring for a client experiencing a stroke is to ensure adequate oxygen supply to the brain, as lack of oxygen can lead to further brain damage. Administering oxygen helps improve oxygenation and can prevent complications. Administering morphine (B) is not recommended as it can mask symptoms and delay diagnosis. Administering IV fluids (C) may be necessary but is not the first priority. Administering fibrinolytics (D) is a time-sensitive intervention for ischemic stroke but should be done after proper evaluation and confirmation of the type of stroke.

Correct Answer: C

Rationale: The correct answer is C: small intestine. This is because the small intestine is where the majority of nutrient absorption takes place due to its large surface area and presence of villi for absorption. The stomach (A) primarily functions in digestion, not absorption. The pancreas (B) produces digestive enzymes but does not directly absorb nutrients. The gallbladder (D) stores bile produced by the liver to aid in digestion but does not participate in absorption directly.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. Dehydration and hypotension indicate fluid loss, which can lead to organ damage and shock. Administering IV fluids helps restore blood volume and improve blood pressure. Monitoring blood pressure (B) is important but addressing the underlying issue of fluid loss is crucial. Administering antihypertensive medications (C) would further lower blood pressure, worsening hypotension. Administering diuretics (D) would exacerbate fluid loss, worsening dehydration and hypotension.

Correct Answer: D

Rationale: The correct answer is D: To treat human responses. This goal aligns with the nursing profession's focus on addressing the holistic needs of individuals. Nurses aim to understand and manage patients' emotional, physical, and psychological responses to illness or treatment. By treating human responses, nurses can improve overall well-being. A: Providing cost-effective care is important but not a broad goal within nursing. It is a component of efficient healthcare delivery. B: Forming broad nursing diagnoses is a part of the nursing process, not a broad goal in itself. C: Promoting self-care is crucial in nursing practice, but it is more of a specific intervention rather than a broad goal encompassing the entire profession.
