Which laboratory results should the nurse closely monitor in a client who has end-stage renal disease (ESRD.?
Serum potassium, calcium, and phosphorus
Erythrocytes, hemoglobin, and hematocrit
Leukocytes, neutrophils, and thyroxine
Blood pressure, heart rate, and temperature
The Correct Answer is A
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.

Correct Answer is D
Explanation
Choice A: Administering a half dose now is not advisable, because it may result in underdosing or overdosing of digoxin. Digoxin has a narrow therapeutic range and a high risk of toxicity, especially in infants and children. The amount of digoxin absorbed by the infant before vomiting is unknown, so giving a partial dose may not achieve therapeutic levels or may exceed safe levels.
Choice B: Giving another dose is not advisable, because it may result in overdosing of digoxin. Digoxin has a narrow therapeutic range and a high risk of toxicity, especially in infants and children. The amount of digoxin absorbed by the infant before vomiting is unknown, so giving a full dose may exceed safe levels and cause adverse effects such as nausea, vomiting, bradycardia, arrhythmias, or visual disturbances.
Choice C: Mixing the next dose with food is not advisable, because it may affect the absorption and bioavailability of digoxin. Digoxin should be taken on an empty stomach or at least one hour before or two hours after meals, because food can interfere with its absorption from the gastrointestinal tract and reduce its effectiveness.
Choice D:Withholding the dose is the safest option. If vomiting occurs within 30 minutes of administration, it’s generally advised to skip that dose to avoid the risk of overdose.The next dose should be given as scheduled Digoxin has a long half-life and accumulates in tissues, so missing one dose will not significantly affect its therapeutic effect. Withholding this dose will avoid overdosing and toxicity of digoxin, which can be life-threatening in infants and children. The nurse should also advise the mother to resume the regular dosing schedule and monitor the infant's pulse rate and signs of digoxin toxicity.
Correct Answer is D
Explanation
Choice A: Mark an outline of the 'olive-shaped' mass in the right epigastric area. This is not a priority action, as it does not address the immediate needs of the infant. The 'olive-shaped' mass is a sign of pyloric stenosis, but it does not affect the infant's hydration or nutrition.
Choice B: Instruct parents regarding care of the incisional area. This is an important action, but not a priority before surgery. The parents need to know how to care for the incisional area after surgery, but this can be done later.
Choice C: Monitor amount of intake and infant's response to feedings. This is a relevant action, but not a priority before surgery. The infant with pyloric stenosis may have vomiting, dehydration, and electrolyte imbalance due to gastric outlet obstruction. Monitoring intake and output can help assess the severity of these problems, but it does not correct them.
Choice D: Initiate a continuous infusion of IV fluids per prescription. This is the priority action before surgery, as it can prevent or treat dehydration and electrolyte imbalance in the infant. IV fluids can also help maintain blood volume and perfusion during surgery.
