Which laboratory results should the nurse closely monitor in a client who has end-stage renal disease (ESRD)?

Choice A reason: Blood pressure, heart rate, and temperature are vital signs that should be monitored in any client, but they are not laboratory results. ESRD can cause hypertension and cardiovascular complications, so blood pressure and heart rate should be controlled with medications and lifestyle modifications. Temperature should be monitored for signs of infection or inflammation.

Choice B reason: Leukocytes, neutrophils, and thyroxine are not specific laboratory results for ESRD. Leukocytes and neutrophils are types of white blood cells that indicate immune system activity and infection. Thyroxine is a thyroid hormone that regulates metabolism and growth. ESRD can affect the immune system and the thyroid function, but these are not the primary indicators of renal function.

Choice C reason: This is the correct answer because serum potassium, calcium, and phosphorus are important laboratory results for ESRD. ESRD can cause electrolyte imbalances that can affect the heart, muscles, nerves, and bones. Serum potassium can increase due to reduced renal excretion and cause cardiac arrhythmias and muscle weakness. Serum calcium can decrease due to impaired absorption and activation of vitamin D and cause muscle cramps, tetany, and osteoporosis. Serum phosphorus can increase due to reduced renal excretion and cause soft tissue calcification and bone pain.

Choice D reason: Erythrocytes, hemoglobin, and hematocrit are laboratory results that measure red blood cell count, oxygen-carrying capacity, and blood volume. ESRD can cause anemia due to reduced production of erythropoietin, a hormone that stimulates red blood cell formation in the bone marrow. Anemia can cause fatigue, pallor, shortness of breath, and chest pain. However, these are not the most significant laboratory results for ESRD.

Choice A reason: This is the correct answer because ineffective coping related to denial is a likely problem for a client who had an MI 24 hours ago and wants to go home despite his condition. Denial is a defense mechanism that helps people avoid facing unpleasant or threatening realities, such as having a heart attack and needing hospitalization and treatment. The nurse should assess the client's coping skills and provide emotional support and education.

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.
