The nurse is assessing a post-operative client and notices that the client's urine is brown and they are experiencing muscle rigidity. The vital signs are T: 102.5 F; HR: 112; RR: 20 and BP 124/84. What is the most appropriate nursing action?

Choice A reason:
Cyanosis, or a bluish discoloration of the skin, particularly in the nail beds, is a sign of inadequate oxygenation and would not indicate successful intervention. The absence of cyanosis would be a positive outcome, reflecting improved oxygen saturation.

Choice B reason:
Lungs clear to auscultation would indicate that air is moving through all regions of the lungs without obstruction from fluid or mucus, which is a sign of recovery from pneumonia. This finding suggests that the interventions aimed at improving gas exchange, such as positioning, deep breathing exercises, and suctioning if needed, have been effective.

Choice C reason: The inability to speak in full sentences often indicates respiratory distress and would not be a sign of successful nursing intervention. An improvement would be the client's ability to speak in full sentences without difficulty, reflecting better lung function and gas exchange.

Choice D reason:
Pulse oximetry readings between 94-96% on room air are within normal limits and indicate adequate oxygen saturation and gas exchange. This is a clear sign that the client's respiratory status has improved, and the interventions for Impaired Gas Exchange have been successful.

Choice E reason:
Bronchovesicular breath sounds are normal breath sounds heard over the major bronchi and are typically moderate in pitch and intensity. However, they are not specifically indicative of successful intervention for Impaired Gas Exchange. The absence of abnormal sounds such as crackles or wheezes would be more relevant.

Choice A Reason
A hemoglobin level of 7.1 g/dL is significantly lower than the normal range, which is typically around 13.8 to 17.2 g/dL for men and 12.1 to 15.1 g/dL for women. This finding is concerning as it indicates severe anemia, which can be a life-threatening condition requiring immediate intervention. Anemia can lead to tissue hypoxia as the blood's capacity to carry oxygen is diminished. In the context of peripheral arterial disease, where blood flow is already compromised, anemia can exacerbate symptoms and increase the risk of ischemic events.

Choice B Reason
Ecchymosis, or bruising, on the client's upper extremities could be a result of the antiplatelet effects of aspirin, which inhibits platelet aggregation and prolongs bleeding time. While this is a concern and warrants monitoring, it is not as immediately life-threatening as severe anemia. However, it does indicate a risk of bleeding complications, which should be addressed by the healthcare provider.

Choice C Reason
A platelet count of 148,000/uL is at the lower end of the normal range, which is approximately 150,000 to 450,000 platelets per microliter of blood. This finding should be monitored, especially in the context of aspirin therapy, which can affect platelet function. However, it is not as critical as the low hemoglobin level.

Choice D Reason
Gastrointestinal discomfort is a common side effect of aspirin due to its irritation of the stomach lining. While this symptom can be uncomfortable and may lead to more serious gastrointestinal issues such as ulcers or bleeding, it is typically not as urgent as severe anemia. The client should be evaluated for potential gastrointestinal complications of aspirin therapy.
