A community health nurse is performing a home visit for a client and is evaluating the home environment for safety. Which of the following findings would indicate to the nurse that the client has a proper understanding of safety in the home?

Choice A reason: Placing the client in semi-Fowler’s position for postoperative assessment is appropriate, promoting lung expansion and reducing aspiration risk. This aligns with standard care, supporting respiratory function and comfort, requiring no further instruction as it reflects safe, evidence-based practice.
Choice B reason: Auscultating lungs without lifting the gown may reduce clarity but is not unsafe. It preserves modesty and is acceptable if effective. While lifting the gown is preferred, this action poses minimal risk, requiring less instruction compared to errors with immediate safety implications.
Choice C reason: Administering an enema without checking for contraindications, like bowel obstruction, risks complications such as perforation. This reflects poor assessment, necessitating instruction to ensure the nurse verifies patient safety and chart details before invasive procedures to prevent harm.
Choice D reason: Checking vital signs before cardiac medication is correct, ensuring safety (e.g., withholding beta-blockers for low heart rate). This follows pharmacological protocols, requiring no instruction, as it demonstrates competence in safe medication administration practices on a medical-surgical unit.

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.
