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

Choice A: Client’s healthcare power of attorney. This is not the first information that the nurse should provide, as it does not address the current situation or problem of the client. The healthcare power of attorney is a legal document that designates who can make medical decisions for the client if they are unable to do so themselves.

Choice B: Currently prescribed medications. This is not the first information that the nurse should provide, as it does not address the current situation or problem of the client. The currently prescribed medications are a part of the background information that can help explain the client’s medical history and potential causes of confusion.

Choice C: Fall at home as reason for admission. This is not the first information that the nurse should provide, as it does not address the current situation or problem of the client. The fall at home is a part of the background information that can help explain the client’s reason for admission and potential injuries.

Choice D: Increasing confusion of the client. This is the first information that the nurse should provide, as it addresses the current situation or problem of the client. The increasing confusion of the client is a part of the assessment information that can help identify the urgency and severity of the issue and guide further interventions.

Choice B reason: Erythrocytes, hemoglobin, and hematocrit are laboratory results that are not as critical as serum potassium, calcium, and phosphorus in a client who has end-stage renal disease (ESRD.. Erythrocytes are red blood cells that carry oxygen from the lungs to the tissues. Hemoglobin is a protein in erythrocytes that binds oxygen. Hematocrit is the percentage of blood volume that is occupied by erythrocytes. ESRD can cause anemia (low erythrocyte, hemoglobin, and hematocrit levels) due to reduced production of erythropoietin, a hormone that stimulates erythrocyte formation, by the kidneys. Anemia can cause fatigue, pallor, or shortness of breath.

Choice C reason: Leukocytes, neutrophils, and thyroxine are laboratory results that are not as relevant as serum potassium, calcium, and phosphorus in a client who has end-stage renal disease (ESRD.. Leukocytes are white blood cells that fight infection and inflammation. Neutrophils are a type of leukocyte that respond to bacterial infection. Thyroxine is a hormone that regulates metabolism and growth. ESRD can cause leukopenia (low leukocyte levels) and neutropenia (low neutrophil levels) due to impaired immune function and increased susceptibility to infection. ESRD can also cause hypothyroidism (low thyroxine levels) due to reduced clearance of thyroid hormones by the kidneys. Hypothyroidism can cause weight gain, cold intolerance, or depression.

Choice D reason: Blood pressure, heart rate, and temperature are not laboratory results, but vital signs that should be monitored in a client who has end-stage renal disease (ESRD.. Blood pressure is the force of blood against the walls of the arteries. Heart rate is the number of times the heart beats per minute. Temperature is the measure of body heat. ESRD can cause hypertension (high blood pressurE. due to fluid overload and activation of the renin-angiotensin-aldosterone system, a hormonal pathway that regulates blood pressure and fluid balance. Hypertension can cause headache, chest pain, or stroke. ESRD can also cause tachycardia (high heart ratE. due to anemia, fluid overload, or electrolyte imbalance. Tachycardia can cause palpitations, dizziness, or heart failure. ESRD can also cause fever (high temperaturE. due to infection or inflammation. Fever can cause chills, sweating, or delirium.
