How to Calculate Cerebral Perfusion Pressure NCLEX Q registerednurseRN.com site

5. A patient's blood pressure is 80/42 and ICP 22. What is the patient's cerebral perfusion pressure and how do you interpret this finding?* A. 33 mmHg, low B. 30 mmHg, normal C. 48 mmHg, low D. 64 mmHg, normal

A. 33 mmHg, low The answer is A: 33 mmHg, low. The MAP is 55. When you calculate the equation: CPP=55-22, you get 33 mmHg as the CPP. Remember a normal CPP is 60-100 mmHg.

2. A patient's mean arterial pressure is 82 and ICP is 15. What is the patient's cerebral perfusion pressure?* A. 67 mmHg B. 100 mmHg C. 52 mmHg D. 30 mmHg

A. 67 mmHg The answer is A: 67 mmHg. The MAP is 82. When you calculate the equation: CPP= 82-15, you get 67 mmHg as the CPP.

4. A patient's blood pressure 92/56 and ICP 6. What is the patient's cerebral perfusion pressure and how do you interpret this finding?* A. 82 mmHg, normal B. 56 mmHg, low C. 62 mmHg, normal D. 108 mmHg, high

C. 62 mmHg, normal The answer is C: 62 mmHg, normal. The MAP is 68. When you calculate the equation: CPP=68-6, you get 62 mmHg as the CPP. Remember a normal CPP is 60-100 mmHg.

1. A patient's blood pressure is 152/96 and ICP is 20. What is the patient's cerebral perfusion pressure?* A. 115 mmHg B. 20 mmHg C. 95 mmHg D. 56 mmHg

C. 95 mmHg The answer is C: 95 mmHg. The MAP is 115. When you calculate the equation: CPP= 115-20, you get 95 mmHg as the CPP.

3. A patient's blood pressure is 110/74 and ICP is 8. What is the patient's cerebral perfusion pressure?* A. 94 mmHg B. 56 mmHg C. 98 mmHg D. 78 mmHg

D. 78 mmHg The answer is D: 78 mmHg. The MAP is 86. When you calculate the equation: CPP= 86-8, you get 78 mmHg as the CPP.
