Correct Answer: B

Rationale: The correct answer is B: Administer an antiemetic as prescribed. Administering an antiemetic helps alleviate nausea and vomiting, providing relief to the patient. This action is based on evidence-based practice and helps improve the patient's comfort and well-being. Offering clear fluids immediately (choice A) may exacerbate nausea. Waiting for the nausea to subside on its own (choice C) may prolong the patient's discomfort. Assessing vital signs (choice D) is important but may not directly address the immediate symptom of nausea.

Correct Answer: B

Rationale: The correct answer is B: Respiratory failure. Patients with COPD have impaired lung function, making them at risk for respiratory failure due to inadequate oxygenation. This can occur due to exacerbation of COPD, infections, or other factors. Monitoring for signs of respiratory distress is crucial. A: Pneumonia - While patients with COPD are at higher risk for pneumonia due to impaired lung function, respiratory failure is a more immediate and critical complication to monitor for in this scenario. C: Hypoglycemia - COPD does not directly increase the risk of hypoglycemia, so monitoring for this complication is not a priority in this case. D: Hypertension - Although some patients with COPD may have hypertension, it is not a common complication directly related to COPD. Monitoring for respiratory failure is more essential in this situation.

Assessing vital signs (choice D) is important but may not directly address the immediate symptom of nausea.

Correct Answer: A

Rationale: The correct answer is A, shortness of breath and weight gain, because fluid overload in patients with chronic kidney disease can lead to pulmonary edema and weight gain due to retained fluid. Shortness of breath occurs as the excess fluid accumulates in the lungs. Increased urine output and fatigue (B) are more indicative of dehydration. Dizziness and hypotension (C) are symptoms of hypovolemia, not fluid overload. Nausea and vomiting (D) are nonspecific symptoms and not typically associated with fluid overload.

Correct Answer: A

Rationale: Rationale: Choice A is correct because using the inhaler at the onset of symptoms can help prevent the asthma attack from worsening. This early intervention can be crucial in managing asthma effectively. Waiting for symptoms to subside (Choice B) can be risky as it may delay necessary treatment. Using the inhaler preventively (Choice C) without symptoms is unnecessary and can lead to overuse. Not using the inhaler for mild symptoms (Choice D) can allow the condition to escalate. Thus, Choice A is the most appropriate response for managing an asthma attack effectively.
