Question

which assessment would the nurse use to identify the possible origin of the problem when an adolescent who has been tardy to school twice in the past week comes to the school nurse complaining of a 2 - day history of low - grade fever, exhaustion, lack of energy, and decreased appetite?
eliciting the kernig sign
eliciting the brudzinski sign
checking for lymphadenopathy
checking the pupillary response to light and accommodation

Explanation:

• Eliciting the Kernig sign: This is a test for meningeal irritation (e.g., meningitis). Symptoms like neck stiffness, not the presented low - grade fever, exhaustion, etc., are more indicative of meningitis - related issues when Kernig sign is relevant.
• Eliciting the Brudzinski sign: Also a test for meningeal irritation. Similar to Kernig sign, it is not directly related to the general symptoms of low - grade fever, exhaustion, lack of energy, and decreased appetite described.
• Checking for lymphadenopathy: Lymphadenopathy (enlarged lymph nodes) can be associated with various infections (viral, bacterial, etc.). Symptoms such as low - grade fever, exhaustion, lack of energy, and decreased appetite can be part of the body's response to an underlying infection that may cause lymph node enlargement.
• Checking the pupillary response to light and accommodation: This is mainly related to neurological assessment of the oculomotor nerve (III) and other aspects of the central nervous system's visual - motor function. It is not typically associated with the general constitutional symptoms (fever, fatigue, etc.) presented.

Answer:

Checking for lymphadenopathy.
