Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. This is the first step in the care of a client with a severe allergic reaction because epinephrine is the primary medication used to reverse the life-threatening symptoms of anaphylaxis. Epinephrine acts quickly to constrict blood vessels, relax smooth muscles in the lungs to improve breathing, and increase heart rate. Administering epinephrine promptly can prevent progression to severe outcomes like respiratory failure or shock. Corticosteroids (B and C) are used as adjunct therapy and do not provide immediate relief. Applying a cold compress (D) does not address the systemic effects of anaphylaxis and can delay potentially life-saving treatment.

Correct Answer: A

Rationale: The correct answer is A: Assess the client's airway. This is the first action because airway patency is the top priority in any emergency situation, including a suspected stroke. Ensuring the client can breathe effectively is crucial to prevent hypoxia and further complications. Administering oxygen (choice B) may be necessary after assessing the airway. Administering aspirin (choice C) should be done after a definitive diagnosis of an ischemic stroke. Performing a CT scan (choice D) is important for diagnosis but is not the first action to take in a suspected stroke scenario.

Correct Answer: B

Rationale: The correct answer is B because asking someone who knows the patient well can provide valuable insight into the meaning behind the verbal and nonverbal communication discrepancy. This helps in understanding the context and potential reasons for the inconsistency. Option A is incorrect as ignoring nonverbal behaviors can lead to missing important cues. Option C of interpreting messages as an 'average' may oversimplify the complexity of communication. Option D is incorrect as while nonverbal behaviors can provide valuable information, solely focusing on them may not give a complete understanding of the situation.

Correct Answer: A

Rationale: The priority nursing intervention for a client with asthma experiencing wheezing is to administer oxygen. Wheezing indicates airway constriction and decreased oxygenation, making oxygen crucial for adequate tissue perfusion. Administering oxygen helps improve oxygen levels, alleviate respiratory distress, and prevent hypoxemia. Applying a bronchodilator (Choice B) may be beneficial after oxygen is administered. Applying a cold compress (Choice C) is not indicated for asthma exacerbations, and encouraging deep breathing (Choice D) may worsen respiratory distress in a client with wheezing. In summary, administering oxygen is the priority intervention to address the immediate respiratory needs of the client with asthma and wheezing.

Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. Nitroglycerin is the recommended initial medication for chest pain in a client with a history of myocardial infarction. It helps dilate blood vessels, improving blood flow to the heart, and reducing chest pain. Aspirin (choice B) is also usually given to reduce blood clot formation, but nitroglycerin is the priority for immediate relief. Morphine (choice C) may be used if nitroglycerin is ineffective, and beta blockers (choice D) are typically used for long-term management of heart conditions, not for immediate relief of chest pain.
