A nurse is preparing to insert a peripheral intravenous line on an infant. Which of the following actions should the nurse plan to take?

Choice A reason: Explaining the implications of a Do Not Resuscitate (DNR) status ensures the client understands that no CPR or intubation will occur if their condition deteriorates. This supports informed consent and autonomy, clarifying the scope of DNR to prevent misunderstandings. It respects the client’s decision-making capacity, ensuring their wishes align with end-of-life care preferences.
Choice B reason: Placing a “Do Not Resuscitate” sign outside the room breaches confidentiality under HIPAA, risking unauthorized disclosure of sensitive information. DNR status is communicated via medical records or wristbands. This action is inappropriate, as it does not contribute to implementing the client’s wishes and violates privacy standards, making it an incorrect response.
Choice C reason: Obtaining family consent is unnecessary for a competent client’s DNR request, as autonomy rests with the client. If decisionally capable, their wishes override family input. The nurse’s role is to support the client’s decision, not seek family approval, unless the client is incapacitated, which is not indicated, making this action inappropriate.
Choice D reason: Documenting the DNR request in the medical record ensures the care team follows the client’s wishes, preventing unwanted interventions. Accurate documentation communicates code status, supports legal and ethical standards, and ensures continuity of care. This is critical for aligning treatment with the client’s end-of-life preferences, making it a necessary action.

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.
