Patho Exam 3

Question 1

(Blood Cell Abnormality) Erythrocytes (RBCS)

Answer 1

4-6 mill/mL

Question 2

(Blood Cell Abnormality) Leukocytes (WBCs)

Answer 2

5k tok/mL

Question 3

(Blood Cell Abnormality) Thrombocytes (platelets) blood clotting

Answer 3

150K-400K/mL

Question 4

Red cells Anemia-low RBC count or low Hgb concentration

Answer 4

HgB- 12-17 gm/dl. 1. Blood loss-Rule out 1st. Tired, not enough oxygen to the cells. Low Red Blood Cell production. High Red Blood Cell destruction. Poler-pail skin, around the eyes.

Question 4

Leukocytopenia/ Leukopenia-low WBC Count

Answer 4

WBC-1.6K/mL. Leukocytosis, high White blood cell Count. 18K/mL- infection present. Inflammation, no infection present causing this.

Question 5

Leukemia

Answer 5

90K/mL-not infection-not treatable to inflammation. Leukemia-cancer & WBC line.

Question 6

Thrombocytopenia-low platelet count

Answer 6

5K/mL-risk of bleeding- prolonged

Question 7

Hematocrit-percentage of RBCs in blood

Answer 7

H/H(Hematocrits percentage in the blood) Hemoglobin- Normal=36%-50%

Question 8

MAP-DBP(Diastolic blood pressure) +1/3 (SBP-Sinomatic blood pressure+ DBP Diastolic Blood pressure)

Answer 8

70+1//3(110-70)=40=1/3(40)=3/40=13.

Question 9

DBP=1/3(PP-pulse pressure) = 70 +1/3(40) =1/3(40) = 70+13=83 mmHg

Answer 9

Diastolic pressure+1/3 (pulse pressure)

Question 10

Hypotension, a BP less than 60, is a problem. BP less than 90/60. 60/30-not happy.

Answer 10

↓BP= ↓CO times ↓SVR/PVR/TPR all the same. ↓BP= ↓CO times ↑ SVR- this can happen. ↓BP=↑ CO times ↑ SVR=not possible. CO=SVR time HR

Question 11

Hypotension-blood loss- ↓ CO bleeding ↓ ↓Blood volume contractility.

Answer 11

Bradycardia-slow heartbeat. Tachycardia-fast heart rate. CO=SVX → ↓BV-bleeding. Vasocontraction- ↑SVR. Vasodilation ↓SVR. Pressure goes down ↓BP = CO times ↓SVR- not enough water. 70/40-hypotension MAP Greater than 60. 40+1/3(70-40) =30 40 +1/3(30) =50. bleeding car accident. Excess flood loss-excess vomiting. Severe vasodilation- vessels constrict-thirsty.

Question 12

drugs that ↑BP = pressors epy, norry-heart constriction.

Answer 12

vasoconstrict-↑ SVR. ↑BP= ↑CO times ↑SVR- given to raise pressure. ↑CO- ↑ HR, ↑ BV/ ↑ contractility. Antidiuretic hormone.

Question 13

Hypertension=high BP (HTN)-Hypertension High BP. BCO times SVR. 1-HTN-95%. 2-HTN.

Answer 13

Stage 1: systolic 130-139 mmHg or Diastolic 80-89 mmHg. Stage 2- systolic greater than 140 mmHg or Diastolic greater than 90 mmHg.

Question 14

High HTN- LV (ventricular) afterload-resistance.

Answer 14

BP=CO times SVR (RAAP). ↓ CO ↚ ↓ BV-diuretic. ↑RAAP-ACE/ARE (↑urine). ↓SNS effect on heart (Beta blocks).

Question 15

Normal BP- Normal L vertical (will pump more blood).

Answer 15

LVH Pertrophy- will not be able to pump more blood. LV- HTN- Myocardial O2 demand→ Myocardial workload. Diastolic Heart Failure. CO=SVR times HR
