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.

Correct Answer: A

Rationale: The correct answer is A: Administer antiemetics. Antiemetics help alleviate nausea and vomiting by blocking neurotransmitters in the brain. This intervention directly targets the symptoms and provides relief for the client. Administering fluids (B) may help with hydration but does not address the root cause. Administering analgesics (C) is for pain relief, not for nausea and vomiting. Monitoring electrolytes (D) is important but does not directly treat the symptoms. Therefore, administering antiemetics is the most appropriate intervention for severe nausea and vomiting.

Correct Answer: D

Rationale: The correct answer is D: Level of consciousness and cognitive abilities. In this scenario, the individual is experiencing delirium due to fluid and electrolyte imbalance, which can affect his level of consciousness and cognitive abilities. Assessing these aspects is crucial in determining the severity of the condition and guiding appropriate interventions. Option A (Affect and mood) is incorrect as the primary concern is the individual's cognitive functioning. Option B (Memory and affect) is incorrect as it does not cover the assessment of consciousness. Option C (Thought processes and memory) is incorrect as it does not specifically address the evaluation of the individual's level of consciousness.

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: B

Rationale: The correct answer is B because conveying respect for differences helps build trust and encourages patients to share their perspectives openly. This fosters a positive patient-provider relationship and enhances communication. Choice A is incorrect as patients have unique behaviors. Choice C is incorrect as cultural expectations do not fully explain individual differences. Choice D is incorrect as expressing one's culture is not solely dependent on exposure to Canadian values.
