Correct Answer: D

Rationale: In a client experiencing drooling and hoarseness following a burn injury, airway compromise is a critical concern. Administering 100% humidified oxygen is the priority to ensure adequate oxygenation. This intervention takes precedence over obtaining baseline ECG, obtaining blood specimens, or inserting an IV catheter, as airway management and oxygenation are fundamental in the initial assessment and management of a client with potential airway compromise.

Correct Answer: B

Rationale: When caring for a client with a newly applied cast, the nurse's priority should be to assess the circulation by palpating the pulse distal to the cast. This is crucial to ensure there is no compromise in blood flow, which could lead to serious complications. Placing an ice pack over the cast, teaching the client about cast care, and positioning the casted extremity on a pillow are important interventions but should follow the assessment of circulation.

Correct Answer: A

Rationale: Generalized petechiae and ecchymoses can indicate a potential issue with platelet function or count. Therefore, the most relevant laboratory test to evaluate this condition would be a platelet count. Platelet count helps assess the number of platelets in the blood, which are crucial for clotting and preventing bleeding. Monitoring platelet levels can provide important information about a client's bleeding risk and overall hematologic health.

Correct Answer: A

Rationale: To calculate the expected delivery date using Nagele's rule, begin by subtracting 3 months from the first day of the last menstrual period (April 12th), which results in January 12th. Then, add 7 days. Therefore, the expected delivery date would be January 19th (0119). This calculation method helps healthcare professionals estimate the client's due date.

Correct Answer: A

Rationale: In this scenario, the nurse should prioritize the client's wishes as outlined in the advance directives. By arranging for an ethics committee meeting, the nurse can facilitate discussions between the family and healthcare team to ensure that the client's wishes are respected while addressing the concerns of the family. This approach promotes ethical decision-making and collaborative communication among all involved parties, ultimately aiming to provide the best possible care for the client while considering their autonomy and preferences.
