The practical nurse (PN) is assisting with collecting health information at a health fair for high school students.
Which information is most important for the PN to obtain?

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.

The practical nurse (PN) should recognize that a newborn whose mother has poorly controlled type 1 diabetes mellitus and is exhibiting grunting with mild sternal retractions is exhibiting signs of patent ductus arteriosus. Patent ductus arteriosus is a condition in which the ductus arteriosus, a blood vessel that connects the pulmonary artery to the aorta, fails to close after birth. This can result in abnormal blood flow between the aorta and pulmonary artery, leading to respiratory distress.

Hypothyroidism (Option A) and hyperinsulinemia (Option C) are conditions that can occur in newborns, but they do not typically present with grunting and sternal retractions.

Ventral septal defect (Option D) is a congenital heart defect that can cause respiratory distress, but it is not specifically associated with maternal diabetes.
