A nurse is caring for a client who is 2 hr postoperative. Which of the following findings should the nurse report to the provider?

Choice A reason: Decreased serotonin levels are linked to depression, as serotonin regulates mood in the brain’s limbic system. Antidepressants like SSRIs increase serotonin, alleviating low mood and anhedonia, making this client a prime candidate for therapy to address neurochemical imbalances in depression.
Choice B reason: Decreased cortisol is not directly tied to depression requiring antidepressants. Cortisol dysregulation may occur in stress disorders, but antidepressants target serotonin or norepinephrine, not adrenal function, making this client less suitable for antidepressant therapy based on this imbalance.
Choice C reason: Elevated dopamine is linked to schizophrenia or mania, not depression. Antidepressants target serotonin or norepinephrine, not dopamine. This client may need antipsychotics or mood stabilizers, not antidepressants, as dopamine excess does not indicate depressive pathology requiring such therapy.
Choice D reason: Elevated thyroid levels suggest hyperthyroidism, mimicking anxiety, not depression. Antidepressants are not indicated, as treatment targets thyroid function. Depression may coexist, but thyroid correction is prioritized, making this client unsuitable for primary antidepressant therapy based on this finding.

Choice A reason: Performing postural drainage immediately after meals risks aspiration and discomfort due to gastric contents shifting during positioning. It should be done 1-2 hours after meals to ensure safety and efficacy in clearing mucus from the lungs, making this timing inappropriate for cystic fibrosis management.
Choice B reason: Performing postural drainage twice daily is recommended for cystic fibrosis to mobilize thick mucus from the lungs, improving airway clearance and reducing infection risk. This frequency balances effectiveness with patient tolerance, aligning with evidence-based guidelines for managing chronic respiratory conditions, making it the correct action.
Choice C reason: Using a percussion vest is an alternative to manual postural drainage but is not specified as the only method. Manual techniques are effective and standard unless a vest is prescribed. This choice assumes equipment availability, which may not apply, making it less universally appropriate than scheduled manual drainage.
Choice D reason: Positioning the child flat during postural drainage is incorrect, as specific angled positions (e.g., head-down) are needed to target lung segments and promote mucus drainage by gravity. Flat positioning reduces effectiveness and may not clear airways adequately, making this an inappropriate technique for cystic fibrosis.
