13

Blood flow TO the glomerulus is provided via the ____________ renal artery. The resting tone of the vessel is primarily regulated by _____________.

afferent, prostaglandins

14

Your patient has been febrile for the past 24 hours. No maintenance fluids have been infusing for the past 12 hours. You would expect your patient to be _____________ with an ___________ sodium level

hypovolemic, increased

15

Which of the following is a benefit of utilizing normovolemic hemodilution as a blood conservation technique?

all of the above are benefits.... sorry there isn't a list of em... ;)

16

Increased __________ increased gut absorption of calcium; while __________ stimulates bone formation, decreasing plasma calcium levels.

calcitriol, calcitonin

17

increased sympathetic nervous system stimulation initiates renin secretion. Renin begins the process of ____________ more sodium from the renal tubule.

retaining.....

RENIN LOVES SALT

18

Which commonly used opiate or opioid medications have active metabolites which may prolong reap depression in the patient with renal failure? (2 of em)

demerol and morphine

19

T/F
Proteins secreted into the ultra filtrate can be easily reabsorbed completely intact across the tubular membranes

False

20

T/F
Patients who live in high altitudes are often polycythemic. The polycythemia is created by increased levels of erythropoietin as a result of lower atmospheric pressures.

False

21

l-arginine vasopressin is secreted by the

posterior neural hypophysis

22

anti-parasympathetic medications may cause

urinary retention

23

Hemophilia A is an abnormality of which clotting factor?

factor 8 (VIII)

24

the final stage in pathogenesis of chronic renal failure is

glomerulosclerosis

25

the kidneys are primarily responsible for regulating free water concentration in the body

false

26

the only test available to evaluate all properties of clot formation and strength is

TEG (thromboelastograph)

27

T/F
Enzyme immunoassays are the most sensitive and specific tests to confirm heparin induced thrombocytopenia, but not the most rapid.

False

28

T/F
Patient's BUN is 18 and the creatinine is 3.6. the patient has azotemia because the patient is clearly in chronic renal failure.

False

Your patent has a Hgb of 7 mg/dL. Based on this finding you would expect a change, if any, to this patient's oxyhemeglobin dissociation curve?

right shift

31

The kidneys receive what percentage of the total cardiac output?

25%

32

T/F
Obese patients must be well-preoxygentated before induction of GA. This is due to decrease in FRC not total lung capacity

False

33

T/F
Decrease in coagulopathy is not a renal protective benefit of ACEI/ ARB medical therapy in patients with chronic renal failure.

False

34

T/F
When there is exposure of collagen from damage to the endothelium, the intrinsic clotting pathway is activated.

True

35

In response to injury, the capillaries

allow more albumin to escape the vascular space.

37

Your patient in septic shock is undergoing massive tissue debridement for necrotizing fasciitis. The patient is on norepinephrine at 30 mcg/min and vasopressin at 0.04u/hr. The starting Hct is 38% and the Lactate level is 5.0 mmol/L. ABG is 7.11/34/197 with bicarb at 17. You resuscitate with 6 liters of normal saline and give 100 mEq sodium bicarbonate as the patient is still hypotensive with a systolic BP of 75.
