The nurse identifies that the goal of decreasing the cardiac workload for a client receiving atenolol 25 mg PO BID for unstable angina is met when the client has:

Choice A Reason
Thiamine, or vitamin B1, is essential for brain function and the metabolism of carbohydrates. In the context of high blood alcohol levels, thiamine is administered to prevent Wernicke's encephalopathy, a serious neurological disorder. This condition is often precipitated by a thiamine deficiency, which can be exacerbated by alcohol abuse. Alcohol consumption can impair thiamine absorption and utilization, leading to depleted stores. Wernicke's encephalopathy is characterized by symptoms such as confusion, ataxia, and ophthalmoplegia, and if left untreated, it can progress to Korsakoff syndrome, a chronic and debilitating condition.

Choice B Reason
While alcoholic hepatitis is a concern in individuals with excessive alcohol intake, thiamine is not specifically used to prevent this condition. Alcoholic hepatitis is inflammation of the liver due to alcohol abuse, and its prevention primarily involves abstinence from alcohol, nutritional support, and medical management of liver inflammation. Thiamine does not play a direct role in preventing liver inflammation but is crucial for overall nutritional replenishment in individuals with alcohol use disorder.

Choice C Reason
Rehydration is indeed important for clients with high blood alcohol levels; however, thiamine does not serve this purpose. Rehydration typically involves the administration of intravenous fluids to restore fluid balance and electrolytes. Thiamine is not a rehydrating agent but is given to prevent neurological complications associated with thiamine deficiency, which can be seen in individuals with chronic alcoholism.

Choice D Reason
Preventing pancreatitis is not the primary reason for administering thiamine in this scenario. Pancreatitis, an inflammation of the pancreas, can be associated with chronic alcohol abuse, but thiamine is not used as a preventative treatment for this condition. The management of pancreatitis involves addressing the underlying causes, supportive care, and sometimes hospitalization for more severe cases.

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.
