Correct Answer: B

Rationale: The correct answer is B because ensuring two nurses double-check medications before administration is a crucial step in minimizing the risk of medication errors. This practice helps in verifying the accuracy of medication orders and reducing the chances of mistakes. Choice A may not necessarily prevent errors as preparing medications ahead of time does not guarantee accuracy. Choice C, administering medications at the same time each day, is important for consistency but does not directly address the risk of errors. Choice D, relying on memory, is highly discouraged as it increases the likelihood of errors due to human forgetfulness.

Correct Answer: A

Rationale: The correct answer is to delegate the task to a licensed practical nurse (LPN). LPNs can typically perform suctioning, but it is essential to consider the state's practice guidelines and hospital policy. Option B, delegating to a registered nurse (RN), is not necessary for this task as LPNs are usually competent to handle suctioning. Option C, delegating to a nursing assistant (NA), may not be appropriate as suctioning may require a higher level of training and expertise. Option D, performing the task independently, is not the best choice as delegation is a key aspect of nursing practice to ensure tasks are appropriately assigned based on competency levels.

Correct Answer: B

Rationale: The priority action when a patient has a fever is to assess the patient's temperature regularly. Monitoring the temperature helps track the effectiveness of interventions and detect any worsening fever. Administering antipyretic medication (Choice A) should be done based on healthcare provider's orders after assessing the patient's condition. While providing cooling measures such as a cool compress (Choice C) can help reduce fever, assessing the temperature takes precedence. Providing blankets for comfort (Choice D) is not the priority when dealing with a fever.

Correct Answer: B

Rationale: The correct answer is B: Prioritize a chest x-ray for the client. When a client presents with severe dyspnea, a chest x-ray should be prioritized as it helps in assessing the lungs and heart, which are crucial in cases of respiratory distress. Echocardiograms are more focused on assessing heart function and may not provide immediate information needed in cases of dyspnea. CT scans and MRIs are more detailed imaging studies that are not typically the first-line diagnostic tests for severe dyspnea.

Correct Answer: A

Rationale: The correct answer is to suction the tracheostomy to maintain a patent airway. After a tracheostomy, the priority intervention is to ensure a clear airway to prevent respiratory distress. Administering pain medication, changing the tracheostomy dressing, and monitoring oxygen saturation are important but are secondary to maintaining a patent airway in a patient who has just undergone a tracheostomy.
