Question

The nurse is calculating the cerebral perfusion pressure (CPP) of an unconscious patient. The patient's blood pressure is 162/58 mm Hg and intracranial pressure (ICP) is 35 mm Hg. What is the patient's CPP? Record your answer using a whole number.

Answer 1

The patient's cerebral perfusion pressure (CPP) is calculated by subtracting the intracranial pressure (ICP) from the mean arterial pressure (MAP), resulting in 57 mm Hg.

Step-by-step explanation:

The cerebral perfusion pressure (CPP) of an unconscious patient can be calculated by subtracting the intracranial pressure (ICP) from the mean arterial pressure (MAP).

The patient's blood pressure is given as 162/58 mm Hg and the ICP is 35 mm Hg. The MAP is not directly given, but it can be calculated using the formula MAP = DBP + 1/3(SBP - DBP), where DBP is diastolic blood pressure and SBP is systolic blood pressure. The MAP for this patient would be 58 + 1/3(162 - 58), which calculates to 92 mm Hg. Therefore, the CPP would be MAP - ICP, resulting in 92 - 35 = 57 mm Hg. Since the question specifies recording the answer using a whole number, the CPP is 57 mm Hg.
