A mother calls the clinic to report that her child has just swallowed "poison" and is vomiting. In preparing to instruct the mother about the necessary action to take, which substance should the practical nurse (PN) consider to be the least traumatic to the esophagus when the child vomits?

The PN should report the injury details to the charge nurse. This is important because the charge nurse needs to be aware of any changes in the patient's condition and can help determine the appropriate course of action. The other options are not the most appropriate actions for the PN to take in this situation.

Obtaining a heel stick glucose (A) may be necessary if hypoglycemia is suspected, but it is not the most immediate concern.

Initiating strict intake and output measurements (C) may be necessary for monitoring fluid balance, but it is not the most immediate concern.

Swaddling the infant in a blanket (D) may provide comfort, but it does not address the underlying issue of the head injury and seizure episode.

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.
