Which finding in an analysis of cerebrospinal fluid (CSF) is consistent with a diagnosis of bacterial meningitis?

Choice A rationale

Circumcision is a surgical procedure that removes the foreskin of the penis. While it is associated with a lower risk of acquiring some sexually transmitted infections like HIV, it does not prevent all of them, making condom use and safe sexual practices the primary preventive measures. Furthermore, this statement is not a balanced, educational response for undecided parents, who require comprehensive information on risks and benefits.

Choice B rationale

Maintaining adequate hygiene is possible in both circumcised and uncircumcised males. For uncircumcised males, proper hygiene involves gently retracting the foreskin daily after infancy to cleanse the glans, preventing the accumulation of smegma. This statement presents an exaggerated and often incorrect difficulty, failing to provide factual, unbiased information to the parents.

Choice C rationale

While the procedure is associated with pain, standard practice involves administering appropriate pain management, such as a dorsal penile nerve block or topical anesthetic, along with non-pharmacologic measures like sucrose solution and non-nutritive sucking. Therefore, the pain is controllable, and this statement is insufficient to guide a final parental decision.

Choice D rationale

The nurse's role is to provide objective information and support the parents' decision-making process, not to give a personal recommendation or push a specific viewpoint. Recommending a discussion with the healthcare provider ensures the parents receive a detailed, evidence-based review of both the potential medical benefits and risks associated with the procedure.

Choice A rationale

Puncturing the lateral or medial plantar surface of the heel is the standard and safest technique for neonatal heel sticks to obtain capillary blood, typically used for glucose screening or newborn screens. This area avoids the central calcaneus bone, reducing the risk of osteomyelitis, and provides sufficient blood flow due to high capillary density, making it the quickest and most common method used one hour after birth. The puncture depth should be less than 2.0 mm.

Choice B rationale

Obtaining a sample from the umbilical cord, while a source of fetal blood, is generally performed immediately at birth for blood typing or gas analysis, not as a quick or common method for routine glucose screening one hour postpartum. Capillary heel stick is preferred as it is less invasive and more suitable for ongoing monitoring in the postnatal period, reflecting the infant's current physiological status.

Choice C rationale

Puncturing a fingertip is not the preferred or common site for capillary blood collection in neonates or infants under one year of age because the fingertip pad lacks sufficient tissue volume and the bone is too close to the surface. Using the heel ensures better blood flow for adequate sampling while minimizing the risk of bone injury and infection, which are greater risks in an infant's small digits.

Choice D rationale

Obtaining a laboratory chemical determination is a broad action describing the analysis of blood components like glucose, but it is not a method of specimen collection itself. The physical action of obtaining the blood sample, which is the focus of the question, must precede the laboratory analysis, making this choice an incomplete answer regarding the collection technique.
