Final answer:
The correct nursing diagnosis for a patient with abruptio placentae is Ineffective Tissue Perfusion. It directly addresses the compromised delivery of oxygen and nutrients to the fetus, which is critical in this condition.
Step-by-step explanation:
The correct nursing diagnosis for a patient with abruptio placentae among the provided options is Ineffective Tissue Perfusion. Abruptio placentae, or premature separation of the placenta from the uterine lining, compromises the delivery of oxygen and nutrients to the fetus because of the impaired circulatory connection between the mother and the fetus. As a result, one of the primary concerns is that the fetus may suffer from inadequate perfusion of tissues, leading to potential hypoxia and nutrient deprivation.
Ineffective Tissue Perfusion is a priority diagnosis because it directly addresses the acute condition that can threaten the life of both the mother and the fetus. The other options, such as Impaired Gas Exchange may apply but are too general and not specific to the condition of abruptio placentae. Similarly, while Risk for Infection is a potential concern, it does not accurately depict the immediate physiological crisis occurring in abruptio placentae. Lastly, Disturbed Body Image is less relevant in the acute phase of this obstetric emergency.
