A 6-week-old infant with pyloric stenosis is scheduled for a pyloromyotomy. Which pre-operative nursing action has the highest priority?

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.

Choice A reason: Notifying the healthcare provider is an important action, but not the first one. The nurse should prioritize interventions that address the client's immediate needs, such as oxygenation and circulation.

Choice B reason: Preparing a continuous heparin infusion per protocol is an appropriate action for preventing further clot formation and reducing the risk of recurrent pulmonary embolism, but it is not the first action. The nurse should first stabilize the client's condition before administering anticoagulant therapy.

Choice D reason: Bringing the emergency crash cart to the bedside is a prudent action, but not the first one. The nurse should prepare for possible cardiopulmonary resuscitation (CPR) in case of cardiac arrest, but should first attempt to prevent it by providing oxygen and other supportive measures.
