What is the most important intervention for a client with acute myocardial infarction (MI)?

Correct Answer: A

Rationale: The correct answer is A: Administer aspirin. Aspirin is crucial for a client with acute MI as it helps prevent further blood clot formation by inhibiting platelet aggregation, reducing chances of additional cardiac events. Oxygen (B) is not routinely recommended unless hypoxemia is present. Morphine (C) can mask symptoms and delay treatment. Nitroglycerin (D) is used to relieve chest pain but may not be the most important intervention in acute MI. Administering aspirin promptly is vital to improve outcomes and reduce mortality in acute MI 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: B

Rationale: The correct answer is B: Administer pain relief. The first priority for a client with an open wound is to manage their pain to ensure their comfort and well-being. Pain relief helps the client relax, reduces stress, and promotes healing. Cleaning and dressing the wound, administering anticoagulants, and monitoring blood pressure are important tasks but are secondary to addressing the client's immediate pain and discomfort. Pain relief should be the initial focus to ensure the client's overall care and recovery.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. This is the best nursing action for a client with a wound infection because antibiotics are necessary to treat the infection at its source, targeting the bacteria causing the infection. Antibiotics help prevent the infection from spreading and promote healing. Explanation of why other choices are incorrect: B: Applying a sterile dressing is important for wound care but does not address the underlying infection. C: Monitoring blood pressure is important for overall patient assessment but does not directly treat the wound infection. D: Placing the client in a sitting position is not relevant to treating a wound infection.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. Epinephrine is the first-line treatment for anaphylaxis, a severe allergic reaction. It works by constricting blood vessels, increasing heart rate, and opening airways, which can reverse the life-threatening effects of an allergic reaction. Antihistamines (B) may help with mild symptoms but are not sufficient for severe reactions. Corticosteroids (C) are used to reduce inflammation but work too slowly for immediate relief. Beta-blockers (D) can worsen allergic reactions by blocking the effects of epinephrine.
