A nurse is admitting an unidentified female infant who was brought to the emergency department. Based on the assessment findings, the nurse should estimate the infant's age to be which of the following? (Click on the "Exhibit" button below for additional client information. There are three tabs that contain separate categories of data)

A. Blood pressure 94/68 mm Hg: While slightly on the lower end for a 7-year-old, mild hypotension may not yet be present in severe dehydration because children often maintain blood pressure until significant fluid loss occurs. Blood pressure alone is not the earliest or most sensitive indicator of severe dehydration.

B. Urinary output 30 mL/hr: Normal urinary output for a child is approximately 1 mL/kg/hr. A child with severe dehydration typically has markedly reduced urine output (oliguria), so 30 mL/hr is still be within a low-normal range depending on the child’s weight

C. Respiratory rate 24/mn: This respiratory rate is within normal limits for a 7-year-old (approximately 18–25 breaths/min). It does not reflect compensation for dehydration or hypovolemia and is not a reliable indicator of severe fluid loss.

D. Heart rate 152/min: Tachycardia is an early and sensitive sign of hypovolemia in children. A heart rate of 152/min is significantly elevated for a 7-year-old, indicating compensatory mechanisms to maintain perfusion in response to severe dehydration.

A. Heart rate 56/min: Bradycardia is not typical during severe alcohol withdrawal. Instead, clients often exhibit tachycardia due to autonomic hyperactivity and increased sympathetic nervous system stimulation.

B. Dry skin: While skin changes can occur, dry skin is not a hallmark of alcohol withdrawal. Other findings such as diaphoresis, tremors, and pallor are more commonly observed.

C. Temperature 38.6°C (101.5°F): Fever is a common sign of severe alcohol withdrawal, reflecting the hypermetabolic state and autonomic hyperactivity associated with withdrawal. Elevated temperature, along with tachycardia, hypertension, and diaphoresis, indicates a more severe withdrawal process that requires close monitoring and intervention.

D. Drowsiness: Severe alcohol withdrawal typically presents with hyperalertness, agitation, and insomnia rather than drowsiness. Lethargy may suggest other complications, but it is not a typical manifestation of acute withdrawal.
