What is the most important intervention for a client experiencing an allergic reaction?

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.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. This is the most appropriate intervention for a wound infection as antibiotics target the underlying bacterial infection causing the wound infection. Antibiotics help to eliminate the infection and prevent it from spreading further. Administering antibiotics is crucial in treating wound infections to promote healing and prevent complications. Choice B (Apply sterile dressing) is incorrect as simply applying a sterile dressing does not address the underlying infection. Choice C (Cleanse and dress the wound) is also incorrect because while wound cleansing is important, it alone may not be sufficient to treat a wound infection. Choice D (Administer analgesics) is incorrect because analgesics only provide pain relief and do not address the infection itself.

Correct Answer: A

Rationale: Administering oxygen is the most important action for a client with respiratory distress because it helps improve oxygen levels in the blood and supports breathing. Oxygen therapy can prevent hypoxia and reduce respiratory workload. Corticosteroids, bronchodilators, and analgesics may be beneficial in specific situations, but they are not the primary intervention for respiratory distress. Corticosteroids reduce inflammation, bronchodilators help open airways, and analgesics provide pain relief but do not directly address the underlying issue of inadequate oxygenation. Administering oxygen should always be the first priority in managing respiratory distress.

Correct Answer: D

Rationale: The correct answer is D: Administer morphine. The rationale is that vomiting after surgery can be a side effect of pain medication such as morphine. By administering morphine, the pain is reduced, which can help alleviate the vomiting. This intervention targets the root cause of the vomiting. Other choices are incorrect because: A: Administering antiemetics may help with nausea but does not address the underlying cause of vomiting. B: Placing the client in a supine position may worsen vomiting due to increased abdominal pressure. C: Encouraging deep breathing may help with relaxation but does not directly address the vomiting caused by pain.

Correct Answer: A

Rationale: The correct answer is A: Administer pain relief. The nurse should address the client's immediate symptom of severe headache to provide comfort and assess the severity of the condition. Pain relief can help decrease anxiety and prevent complications. Monitoring vital signs (B) is important but treating the symptom should take priority. Monitoring ECG (C) is not necessary for a headache presentation. Administering insulin (D) is not indicated for a client presenting with a severe headache.
