Correct Answer: C

Rationale: A stab wound to the chest is the highest priority injury. This type of injury can lead to lung collapse and mediastinal shift, potentially resulting in death if left untreated. Treating an obstructed airway or a chest wound takes precedence over addressing hemorrhage. The principle of ABC (airway, breathing, and circulation) guides care decisions in prioritizing life-threatening situations. An open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate threat to life compared to a stab wound to the chest. An open leg fracture may lead to significant blood loss but is not immediately life-threatening. An open head injury requires assessment and intervention but does not impact airway, breathing, or circulation directly. Traumatic amputation of a thumb is a serious injury but can be managed after addressing more life-threatening conditions.

Correct Answer: A

Rationale: The correct answer is pain on movement and weight bearing. This pain is the primary sign of prosthesis displacement after a total hip replacement, indicating pressure on nerves or muscles due to dislocation. Hemorrhage is not typically associated with prosthesis displacement. While the affected leg may appear longer, this is not the primary sign of displacement; it might actually be shorter due to muscle spasm. Edema in the incision area is not a primary indicator of prosthesis displacement.

Correct Answer: B

Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.

Correct Answer: D

Rationale: Thrombocytopenia is an abnormal decrease in the number of platelets, which results in bleeding tendencies. During chemotherapy, bone marrow depression can lead to a reduction in platelet production, causing thrombocytopenia. Erythrocytosis is an abnormal increase in red blood cells, leukocytosis is an increase in white blood cells, and polycythemia is an excess of red blood cells, which is synonymous with erythrocytosis. In the context of chemotherapy, the focus is on the decrease in red and white blood cells, making thrombocytopenia the most relevant finding.

Correct Answer: C

Rationale: The priority intervention for preventing respiratory complications in a client with advanced COPD who underwent gallbladder surgery is to get the client out of bed 4 times daily. This helps prevent pooling of secretions in the lungs and promotes better lung expansion. Incentive spirometry, coughing, and deep breathing are essential interventions; however, they should be performed more frequently, ideally every 1 to 2 hours, rather than every 4 hours or 4 times daily. Giving oxygen at 4 L/minute could potentially decrease the client's respiratory drive, which is not the priority in this case.
