A nurse is discussing antidepressant therapy with a provider. Which of the following clients should the nurse identify as being a candidate for antidepressant therapy?
A client who has decreased serotonin levels.
A client who has decreased cortisol levels.
A client who has elevated dopamine levels.
A client who has elevated thyroid levels.
The Correct Answer is A
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.

Correct Answer is A
Explanation
Choice A reason: Abdominal pain is a hallmark of ectopic pregnancy, where the embryo implants outside the uterus, often in the fallopian tube. Tissue stretching or rupture causes localized pain, driven by tubal irritation or internal bleeding, requiring urgent evaluation to prevent life-threatening hemorrhage in affected clients.
Choice B reason: Hydramnios, excessive amniotic fluid, occurs in intrauterine pregnancies, not ectopic ones, which lack a uterine gestational sac. Ectopic pregnancies cannot produce amniotic fluid, as implantation occurs outside the uterus, making hydramnios an irrelevant finding in this condition’s pathophysiology.
Choice C reason: Profuse vaginal bleeding is uncommon in ectopic pregnancy, which typically causes spotting or mild bleeding. Heavy bleeding suggests miscarriage or other conditions. Ectopic pregnancies cause internal bleeding, leading to abdominal pain, not profuse vaginal hemorrhage, a key diagnostic distinction.
Choice D reason: Elevated blood pressure is not typical in ectopic pregnancy unless complicated by pain-induced stress or shock. Internal bleeding from ectopic rupture often lowers blood pressure due to hypovolemia, making hypertension an unlikely finding compared to the expected abdominal pain presentation.
Correct Answer is B
Explanation
Choice A reason: Financial power of attorney manages monetary decisions, not health care, unless specified as a health care surrogate. Advance directives guide health decisions, but this role is distinct, making this statement incorrect under the Patient Self-Determination Act’s provisions.
Choice B reason: The Patient Self-Determination Act ensures clients’ rights to refuse treatment, even against provider recommendations, promoting autonomy through advance directives. This legal protection applies in Medicare/Medicaid facilities, making it the correct principle for end-of-life decision-making in this context.
Choice C reason: Advance directives can be changed by a competent client, even if notarized, as the Act supports ongoing autonomy. Stating they cannot be altered is incorrect, as flexibility is a core feature, making this an inaccurate representation of the law.
Choice D reason: The eldest adult child cannot change advance directives unless designated as a surrogate. The Act prioritizes the client’s documented wishes or appointed decision-maker, not family hierarchy, making this statement incorrect and misaligned with legal requirements.
