Correct Answer is C

Explanation

A. Taking the infant's vital signs every 2 hr: Monitoring vital signs every 2 hours can help assess the infant’s general condition and detect changes in heart rate and blood pressure, which can indicate changes in hydration status. However, it might not be sufficient alone to monitor fluid status.

B. Counting the number of wet diapers every shift: Tracking the number of wet diapers is an effective way to monitor the infant's fluid output and hydration status. An increase in wet diapers typically indicates improved hydration. This is a practical and non-invasive method for assessing the effectiveness of IV therapy in infants.

C. Weighing the infant at the same time every day: Daily weights are a critical measure of fluid balance in infants. A consistent daily weight check provides a direct and accurate assessment of the infant’s hydration status and response to IV therapy.

D. Measuring the infant's head circumference twice per day: Measuring head circumference is not relevant for monitoring hydration status. It is typically used to assess growth and development in infants, not fluid balance or response to IV therapy.

A. Scoliosis B. Ankylosis C. Kyphosis D. Lordosis

Correct Answer is A

Explanation

A. Scoliosis: Scoliosis is characterized by an abnormal lateral curvature of the spine, commonly detected during routine physical exams in school-aged children and adolescents. This is the correct diagnosis for the described symptom.

B. Ankylosis: Ankylosis refers to joint stiffness or immobility due to fusion of the bones, not a lateral curvature of the spine. It is typically associated with conditions like ankylosing spondylitis and does not describe a spinal curvature.

C. Kyphosis: Kyphosis involves an abnormal forward curvature of the spine, often resulting in a hunchback appearance. It is not the same as a lateral curvature and thus does not fit the description given.

D. Lordosis: Lordosis is characterized by an exaggerated inward curve of the lower spine, commonly referred to as swayback. It does not involve lateral curvature and therefore is not relevant to the described condition.
