Final answer:
The nurse would anticipate a blood pressure of 136/84 in a child with acute glomerulonephritis because this condition can cause hypertension due to fluid and sodium retention. Other vital signs like respirations and pulse rate may be elevated, but the elevated blood pressure is the most indicative of this particular diagnosis.
Step-by-step explanation:
The nurse is collecting data on a 6-year-old child admitted with acute glomerulonephritis and would anticipate certain alterations in the child's vital signs. Among the options provided, a blood pressure of 136/84 is likely to be the anticipated vital sign. Acute glomerulonephritis can cause hypertension due to the body's retention of excess fluid and sodium, as well as disturbances in the renin-angiotensin system, a key regulator of blood pressure. Therefore, an elevated blood pressure reading such as 136/84 mm Hg is consistent with this diagnosis and indicates hypertension for a child of this age.
As a reference, normal blood pressure for a child this age is typically lower than in adults, and a blood pressure reading above 120/80 mm Hg could indicate hypertension. Respirations at 24 per minute and a pulse rate of 112 bpm may be somewhat elevated but are not as specifically indicative of acute glomerulonephritis as the elevated blood pressure is. Pulse oximetry at 93% could indicate mild hypoxemia, but this is not a typical finding in acute glomerulonephritis unless there is an underlying respiratory or systemic issue.
