For a client with diabetes mellitus, which new lab finding is the greatest concern?

Choice A reason:
Being free of chest pain and dyspnea is a significant indicator of successful nursing intervention in a sickle cell crisis. Chest pain and dyspnea can occur due to acute chest syndrome, a life-threatening complication of sickle cell disease characterized by vaso-occlusion in the pulmonary microcirculation. Effective pain management and oxygen therapy can alleviate these symptoms, reflecting improved respiratory function and gas exchange.

Choice B reason:
Educating the client on the importance of increasing fluid intake is crucial in managing sickle cell crisis. Adequate hydration helps to reduce blood viscosity and prevent sickling of red blood cells, which can lead to vaso-occlusive episodes. When a client verbalizes understanding and the importance of hydration, it demonstrates the effectiveness of patient education and the client's engagement in self-care.

Choice C reason:
While increasing aerobic exercises may promote endurance, it is not typically a short-term outcome measure for a sickle cell crisis. Exercise must be approached with caution in these clients, as it can increase the risk of a vaso-occlusive crisis due to dehydration and increased oxygen demand during a sickle cell crisis.

Choice D reason:
Control of acute pain to a level of 3 on a standard pain scale indicates successful pain management, a primary goal in the treatment of sickle cell crisis. Pain in sickle cell crisis is due to ischemia from obstructed blood flow by sickled cells. Effective analgesic administration and pain management strategies are essential to achieve this outcome.

Choice E reason:
A leukocyte count of 18,000/mm³ is above the normal range (4,500 to 11,000/mm³) and may indicate an infection or inflammation, which are common complications of sickle cell disease. However, this is not a direct outcome of nursing interventions aimed at managing a sickle cell crisis and thus is not a correct choice.

Choice A reason:
Administering an antiemetic is an important intervention in the PACU, especially if the patient is experiencing nausea or has a history of postoperative nausea and vomiting (PONV). However, it is not the first priority. Antiemetics work by blocking the neurotransmitters that trigger the vomiting reflex. Medications such as ondansetron or promethazine may be used.

Choice B reason:
Applying sequential compression devices is a preventive measure against deep vein thrombosis (DVT), which is a risk due to immobility after surgery. These devices help improve venous return from the lower limbs by applying intermittent pressure. While important, this intervention follows after the assessment of vital signs.

Choice C reason:
Assessing vital signs is the first and foremost priority when a patient is transferred to the PACU. Vital signs, including blood pressure, heart rate, respiratory rate, and oxygen saturation, provide immediate information about the patient's hemodynamic status and can indicate the need for urgent interventions. Any evidence of respiratory or circulatory compromise requires immediate attention.

Choice D reason:
Hanging the Lactated Ringers solution is part of managing the patient's fluid status postoperatively. Lactated Ringers is an isotonic solution that helps to replace lost fluids and maintain electrolyte balance. While important for patient care, it is not the initial priority upon arrival in the PACU.
