To preserve cerebral perfusion of a patient with an elevated intracranial pressure (ICP), which cerebral perfusion pressure (CPP) would the nurse maintain when suctioning the patient?

80 mm Hg

20 mm Hg

40 mm Hg

60 mm HG

Answer and Explanation

The Correct Answer is A

A.   Cerebral perfusion pressure (CPP) is crucial for maintaining adequate blood flow to the brain. A CPP of 80 mm Hg is typically considered the lower limit for preserving cerebral perfusion, particularly in patients with elevated ICP.
B.   20 mm Hg is too low and would indicate inadequate perfusion, which could result in brain ischemia.
C.   40 mm Hg is too low for optimal cerebral perfusion in critically ill patients with elevated ICP.
D.   60 mm Hg is also too low for optimal cerebral perfusion in critically ill patients with elevated ICP.

Correct Answer is D

Explanation

A. Avoid friction over scaly lesions while bathing is generally good advice, but it is not the primary focus in this situation.
B. Eliminate the use of products containing salicylic acid is not necessary unless the client has a known sensitivity or reaction to it, as salicylic acid is commonly used to treat psoriasis.
C. Maintain occlusive dressings on the lesions throughout the day and remove them at bedtime is not typically recommended for psoriasis, as it can exacerbate the condition or increase irritation. Topical treatments, if prescribed, should be used as directed.
D. Psoriasis is often exacerbated by stress. Therefore, teaching the client effective stress reduction techniques (e.g., meditation, deep breathing, yoga) can help in managing flare-ups.

A. Regulation of constriction and dilation of blood vessels in the brain B. Regulation of catecholamines circulating throughout the body C. Regulation of the amount of carbon dioxide exhaled D. Regulation of how much blood is pumped from the heart

Correct Answer is A

Explanation

A. The constriction and dilation of blood vessels in the brain helps maintain appropriate cerebral blood flow and cerebral perfusion pressure (CPP) despite fluctuations in blood pressure.
B. Catecholamines regulate other systemic body functions, but they do not directly impact cerebral perfusion pressure.
C. Carbon dioxide exhalation can affect blood flow, but the primary regulation of CPP is through blood vessel constriction and dilation.
D. The amount of blood pumped from the heart can impact overall blood pressure but does not directly regulate cerebral perfusion pressure.
