What is the primary concern for a client with dehydration and hypotension?

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: 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 epinephrine. Epinephrine is the first-line treatment for anaphylaxis as it quickly reverses severe allergic reactions. It works by constricting blood vessels, relaxing airway muscles, and increasing heart rate. These actions help to counteract the potentially life-threatening symptoms of anaphylaxis, such as difficulty breathing and a drop in blood pressure. Applying antihistamines (B) may help with mild allergic reactions but are not sufficient for anaphylaxis. Administering morphine (C) or pain relief (D) is not appropriate initially as they do not address the immediate life-threatening nature of anaphylaxis.

Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. This is crucial for preventing blood clots post-surgery as they help thin the blood and reduce clot formation. Monitoring for arrhythmias (B) is important but not the priority in this case. While encouraging deep breathing (C) and fluid intake (D) are beneficial for post-surgical recovery, they do not directly address the risk of blood clot formation. Administering anticoagulants is the most effective intervention to prevent blood clots in high-risk surgical patients.

Correct Answer: B

Rationale: The correct answer is B: Place the client in a supine position. This is the first step when administering Heparin to prevent bleeding or bruising at the injection site. Placing the client in a supine position helps reduce the risk of injury and promotes optimal absorption. Administering antipyretics (Choice A) is not the first step in administering Heparin. Administering insulin (Choice C) is unrelated to Heparin administration. Monitoring vital signs (Choice D) is important but typically done after the initial step of positioning the client correctly.
