Which primary lesions are associated with acne caused by sebum blockage in hair follicles?

Choice A rationale

A CPP within normal limits ranges from 60 to 80 mm Hg, so a value of 40 mm Hg is not within this range.

Choice B rationale

A CPP of 40 mm Hg is considered low and indicates inadequate cerebral blood flow, which can result in brain ischemia and damage.

Choice C rationale

The reading of 40 mm Hg is considered accurate, as it reflects the current CPP of the client.

Choice D rationale

A CPP of 40 mm Hg is not high but low, indicating compromised cerebral perfusion.

Choice A rationale

The peripheral nervous system (PNS) consists of all the nerves outside the brain and spinal cord. It transmits signals to and from the central nervous system but does not specifically regulate energy expenditure.

Choice B rationale

The parasympathetic nervous system is part of the autonomic nervous system that promotes "rest and digest" functions, conserving energy by slowing the heart rate and increasing intestinal and gland activity.

Choice C rationale

The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body to expend energy rapidly in response to perceived threats. It increases heart rate, dilates airways, and mobilizes energy stores.

Choice D rationale

The central nervous system (CNS) consists of the brain and spinal cord. It is responsible for processing information and coordinating bodily functions but does not specifically regulate energy expenditure.
