A nurse is obtaining the length and weight of a 6-month-old infant. Which of the following actions should the nurse take? (Select all that apply.)

Choice A reason: Hypovolemia is a condition of low blood volume due to fluid loss from the burn injury. It can cause decreased urine output, hypotension, tachycardia, and poor skin turgor. The nurse should monitor the client's vital signs, fluid intake and output, and weight. The nurse should administer lactated Ringer's solution to maintain urine output of 30 ml/hr.

Choice B reason: Hyperkalemia is a condition of high potassium levels in the blood due to cellular damage from the burn injury. It can cause peaked T waves, dysrhythmias, muscle weakness, and cardiac arrest. The nurse should monitor the client's serum potassium levels, electrocardiogram, and cardiac status. The nurse should avoid administering potassium-containing fluids or medications.

Choice C reason: Hypocalcemia is a condition of low calcium levels in the blood due to fluid shifts from the burn injury. It can cause positive Chvostek's sign, tetany, seizures, and hypotension. The nurse should monitor the client's serum calcium levels, neurological status, and blood pressure. The nurse should administer calcium supplements as prescribed.

Choice D reason: Hypernatremia is a condition of high sodium levels in the blood due to fluid loss from the burn injury. It can cause dry mucous membranes, thirst, agitation, and seizures. The nurse should monitor the client's serum sodium levels, hydration status, and mental status. The nurse should administer hypotonic fluids as prescribed.

Choice A reason: Tremors are not a likely finding in a child with hyperglycemia, or high blood glucose. Tremors are more commonly associated with hypoglycemia, or low blood glucose, as the body releases adrenaline to stimulate the release of glucose from the liver. Tremors may also be caused by anxiety, caffeine, or certain medications.

Choice B reason: Shallow respirations are not a likely finding in a child with hyperglycemia, unless the child has developed diabetic ketoacidosis (DKA), a serious complication of diabetes that occurs when the body breaks down fat for energy and produces ketones, which are acidic substances that can cause metabolic acidosis. In DKA, the child may have rapid and deep breathing, also known as Kussmaul respirations, as the body tries to eliminate excess carbon dioxide and acid. However, DKA usually occurs when the blood glucose level is above 300 mg/dL, and the child may also have other signs and symptoms, such as nausea, vomiting, abdominal pain, fruity breath, and confusion.

Choice C reason: Pallor is not a likely finding in a child with hyperglycemia, as the blood flow to the skin is not affected by high blood glucose. Pallor is more commonly associated with anemia, shock, or hypoxia, which are conditions that reduce the oxygen-carrying capacity of the blood or the blood flow to the tissues.

Choice D reason: Lethargy is a likely finding in a child with hyperglycemia, as high blood glucose can cause dehydration, electrolyte imbalance, and impaired brain function. The child may feel tired, weak, and drowsy, and have difficulty concentrating or staying awake. Lethargy may also indicate that the child is at risk of developing DKA, which can lead to coma and death if not treated promptly.
