4: Urologic evaluation of the child Flashcards
When evaluating a child with a urologic condition, why is it important to approach family members with sensitivity and patience?
A. Because family members may be uncooperative during the encounter
B. Because the family members are often the source of the child’s anxiety
C. Because the family members may not be aware of the child’s symptoms
D. Because approaching the family members with sensitivity and patience helps establish a trustful relationship
D. When evaluating a child with a urologic condition, it is critical to approach family members with sensitivity and patience to establish a trustful relationship. Open expression of the provider’s awareness of their anxiety, along with respecting the privacy of older children, is important in establishing a good rapport with the family.
When asking the historian to report their experience and observations, what is the best way to approach the questions?
A. Ask for a diagnosis or judgment of “normalcy.”
B. Ask about frequency and consistency of stool rather than if a child is “constipated.”
C. Ask the parent to describe the child’s symptoms in their own words.
D. Ask the parent to list all the possible causes of the child’s symptoms.
B. When asking the historian to report their experience and observations, it is best to ask about frequency and consistency of stool rather than if a child is “constipated.” Asking about specific symptoms, rather than using diagnostic terminology, can help avoid confusion and promote clarity in communication.
How can engaging the child in a nonthreatening activity or discussion facilitate a successful evaluation?
A. By distracting the child from the discomfort of the examination
B. By making the child more anxious and uncooperative
C. By making the child more aware of their symptoms
D. By allowing the child to relax during the encounter
D. Engaging the child in a nonthreatening activity or discussion can help facilitate relaxation during the encounter, making it easier for the healthcare provider to perform a successful evaluation.
When should the physical examination be performed when evaluating a child with a urologic condition?
A. At the beginning of the encounter
B. After the guardian has left the room
C. At the end of the encounter
D. Before taking a history
C. The physical examination should be performed at the end of the encounter to prevent the guardian from missing out on important clinical details if the child becomes upset.

How can hydrocele fluid appear during a pediatric urologic evaluation?
A. Red
B. Yellow
C. Blue
D. Green
C. During a pediatric urologic evaluation, hydrocele fluid (and neonatal bowel) transilluminates and may appear blue through scrotal skin. This can be a useful diagnostic tool for identifying a hydrocele, which is a common condition in pediatric patients.
