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 A reason: This is the correct answer because serum potassium, calcium, and phosphorus are laboratory results that should be closely monitored in a client who has end-stage renal disease (ESRD). ESRD is a chronic condition that causes irreversible loss of kidney function and accumulation of waste products and fluids in the body. Potassium is an electrolyte that regulates nerve and muscle function and cardiac rhythm. ESRD can cause hyperkalemia (high potassium levels) due to reduced excretion by the kidneys. Hyperkalemia can cause cardiac arrhythmias, muscle weakness, or paralysis. Calcium and phosphorus are minerals that maintain bone health and acid-base balance. ESRD can cause hypocalcemia (low calcium levels) due to impaired vitamin D metabolism and hyperphosphatemia (high phosphorus levels) due to reduced excretion by the kidneys. Hypocalcemia can cause muscle cramps, tetany, or seizures. Hyperphosphatemia can cause soft tissue calcification, bone pain, or fractures.
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 C
Explanation
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 C reason: This is the correct answer because providing supplemental oxygen is the first action that the nurse should take to improve the client's oxygenation and reduce hypoxia. Pulmonary embolism can cause impaired gas exchange and respiratory distress, which can lead to cardiac arrest and death if not treated promptly.
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.
Correct Answer is A
Explanation
Choice A reason: This is the correct answer because moderate amount of foul-smelling lochia is a sign of endometritis, which is an infection of the uterine lining that can occur after delivery. Endometritis can cause fever, pelvic pain, and uterine tenderness.
Choice B reason: Blood pressure of 122/74 mm Hg is within the normal range for a postpartum client and does not indicate an infection. However, the nurse should monitor for signs of preeclampsia or eclampsia, such as hypertension, proteinuria, headache, blurred vision, and seizures.
Choice C reason: Oral temperature of 100.2°F (37.9°C) is slightly elevated, but not necessarily indicative of an infection. A mild fever may occur within the first 24 hours after delivery due to dehydration or hormonal changes. However, if the fever persists or increases, the nurse should suspect an infection and notify the healthcare provider.
Choice D reason: White blood cell count of 19,000/mm^3 (19 x 10^9/L) is higher than the normal range, but not necessarily indicative of an infection. A leukocytosis or increased WBC count may occur as a normal response to stress or trauma during delivery. However, if the WBC count remains elevated or increases further, the nurse should suspect an infection and notify the healthcare provider.
