The practical nurse (PN) is caring for a 3-month-old infant with a head injury who had a seizure episode. The infant has a high-pitched cry and is irritable. The caregiver reports that the infant rolled over and fell onto the carpeted floor. Which action should the PN take?

Rationale:

A. Increased appetite is not a direct therapeutic indicator of baclofen efficacy. While improved comfort from muscle relaxation might indirectly support better intake, the drug does not possess orexigenic properties. Nutritional status is monitored in cerebral palsy patients, but it remains unrelated to the specific pharmacological mechanism of this skeletal muscle relaxant.

B. Sufficient urinary output is a vital assessment of general physiological and renal function, yet it is not the target of baclofen therapy. Baclofen acts primarily on the central nervous system to inhibit monosynaptic and polysynaptic reflexes at the spinal level. Urinary monitoring ensures adequate drug clearance, but output levels do not reflect the medication's clinical success.

C. Fewer temper outbursts might suggest a reduction in physical discomfort, but baclofen is not an antianxiety or antipsychotic medication. Cerebral palsy may involve behavioral challenges, but the primary goal of this therapy is physical rather than psychological. Behavioral changes are subjective and do not provide a scientific measure of the drug’s specific muscle-relaxing influence.

D. Decreased muscular spasticity is the primary therapeutic goal for a client with cerebral palsy receiving baclofen. This medication functions as a gamma-aminobutyric acid (GABA) analogue, effectively reducing the transmission of excitatory signals that cause hypertonia and involuntary muscle contractions. A reduction in resistance to passive movement confirms that the drug is achieving its intended neuromuscular effect.

To best help develop interventions for a toddler with failure to thrive due to inadequate caloric intake, the practical nurse (PN) should monitor parent-toddler interaction. Observing how the parent and toddler interact during mealtimes can provide valuable information about the child's eating habits and any potential issues that may be contributing to the inadequate caloric intake. The PN can use this information to develop interventions that address any identified issues and promote healthy eating habits. The other observations listed may also be important to monitor, but observing parent-toddler interaction is the most useful in this situation.
