A patient experiences a gasoline tank fire when riding a motorcycle and is admitted to the emergency department (ED) with partial-thickness burns on the anterior surfaces of both lower extremities. Which percentage of body surface area should the nurse document in the electronic medical record (EMR)?

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.

Choice A reason: This is a correct answer because flushing the tube with more water is important to prevent clogging and maintain hydration. The novice should flush the tube with at least 15 mL of water before and after each medication, and between medications if more than one is given.

Choice B reason: This is a correct answer because administering each medication separately is important to prevent interactions and ensure accurate dosing. The novice should not mix different medications in one syringe or container, but give them one at a time, followed by water flushes.

Choice C reason: This is not a correct answer because adding the liquid volumes when documenting fluid intake is not necessary. The liquid medications do not count as fluid intake, but as medication administration. The novice should document the type, dose, route, and time of each medication given, as well as any adverse effects or complications.

Choice D reason: This is a correct answer because confirming that the novice determined the amount of gastric residual is important to assess tolerance and prevent aspiration. The novice should aspirate the gastric contents with a syringe before giving any medication or feeding, and measure and document the volume. If the volume is more than 100 mL or the prescribed amount, the novice should hold the medication or feeding and notify the healthcare provider.

Choice E reason: This is not a correct answer because advising the novice to use the plunger when giving medications is not recommended. The novice should use gravity to deliver the medications through the tube, by holding the syringe upright and allowing the liquid to flow slowly. Using the plunger can cause too much pressure and damage the tube or cause discomfort to the client.
