When learning about the nervous system, students learn that which nervous system regulates the expenditure of energy?

Choice A rationale

A cerebral perfusion pressure (CPP) of 40 mm Hg is considered low, as the normal range for CPP is typically between 60 and 80 mm Hg. Low CPP can lead to inadequate blood flow to the brain.

Choice B rationale

An accurate CPP reading is crucial for assessing intracranial pressure and cerebral blood flow. A reading of 40 mm Hg is not typically considered inaccurate.

Choice C rationale

A CPP of 40 mm Hg is not within normal limits, as it is significantly below the normal range.

Choice D rationale

A CPP of 40 mm Hg is not high; it is considered low and requires medical attention.

Choice A rationale

Percutaneous absorption of topical corticosteroids increases systemic exposure, potentially causing side effects like adrenal suppression, hyperglycemia, and Cushing's syndrome. This is particularly significant when potent corticosteroids are applied to large body areas or under occlusive dressings, enhancing absorption and systemic effects.

Choice B rationale

Topical corticosteroids primarily induce vasoconstriction, not vasodilation, reducing inflammation and redness in skin conditions. Incorrect understanding of their vasodilatory effects may misguide nursing interventions, making it less relevant to the injury risk in atopic dermatitis treatments.

Choice C rationale

Topical corticosteroids have minimal systemic interactions compared to oral or intravenous forms, making drug interaction concerns less pertinent. The risk of significant drug interactions is low unless the medication is systemically absorbed in substantial amounts.

Choice D rationale

Application to face, neck, and intertriginous sites increases the risk of local side effects like skin atrophy, but is not a primary concern for systemic injury risk. These areas have thinner skin, enhancing absorption and risk of local adverse effects, but not necessarily systemic harm.
