When assessing a multigravida on the first postpartum day, the nurse finds a moderate amount of lochia rubra, with the uterus firm and three fingerbreadths above the umbilicus. What action should the nurse implement first?

Choice A: Obtain a blood pressure reading before the client gets out of bed. This is the most important intervention, as it can prevent or detect orthostatic hypotension, which is a drop in blood pressure when changing position from lying to standing. Orthostatic hypotension can cause dizziness, fainting, or falls, and it can be caused by medications, dehydration, or cardiac problems.

Choice B: Monitor and record the client's urinary output every day. This is not the most important intervention, as it does not address the client's anxiety or adjustment issues. The urinary output should be monitored for signs of fluid balance, kidney function, or infection, but it is not a priority for this client.

Choice C: Provide the client with teaching regarding a cardiac diet. This is not the most important intervention, as it does not address the client's anxiety or adjustment issues. The cardiac diet should be taught to promote heart health, lower cholesterol, and reduce sodium intake, but it is not a priority for this client.

Choice D: Assess the client's vital signs every 4 hours when awake. This is not the most important intervention, as it does not address the client's anxiety or adjustment issues. The vital signs should be assessed for signs of infection, pain, or hemodynamic instability, but they are not a priority for this client.

Choice B reason: Emotional conflict due to stress is not a specific problem for a client who had an MI 24 hours ago and wants to go home despite his condition. Emotional conflict is a state of having mixed or contradictory feelings about something or someone, such as family, work, or self. Stress is a response to any physical, psychological, or environmental demand that exceeds one's coping resources. The nurse should assess the client's sources of stress and conflict and help him manage them.

Choice C reason: Deficient knowledge of MI lifestyle changes is not a primary problem for a client who had an MI 24 hours ago and wants to go home despite his condition. Deficient knowledge is a state of lacking information or understanding about something, such as disease process, treatment options, or self-care measures. Lifestyle changes are modifications in one's habits or behaviors that promote health and well-being, such as diet, exercise, smoking cessation, or stress management. The nurse should assess the client's learning needs and readiness and provide appropriate education.

Choice D reason: Anxiety related to treatment plan is not an evident problem for a client who had an MI 24 hours ago and wants to go home despite his condition. Anxiety is a feeling of apprehension, worry, or fear that interferes with one's normal functioning or well-being. Treatment plan is a set of goals, interventions, and outcomes that guide the care of a client with a specific health problem, such as MI. The nurse should assess the client's level of anxiety and provide information and reassurance about his treatment plan.
