Intro to the Kidney MCQ
Question 1 |
What are the three components of the glomerular filtration barrier and their filtration characteristics?
Fenestrated endothelium (filters based on size and shape), hepatocytes (filters based on size and shape), type 2 pneumocytes (filters based on size and shape)
| |
Blood vessel (filters based on charge), glomerulous (filters based on size and shape), bowman’s capsule (filters based on size and shape)
| |
Fenestrated endothelium (filters based on size and shape), basement membrane (filters based on charge), podocytes (filters based on size and shape)
| |
2 layers of fenestrated endothelium (filters based on size and shape), Basement membrane (filters based on charge) |
Question 2 |
Which of the following is not produced by the kidney?
EPO | |
1-alpha hydroxylase | |
Angiotensin converting enzyme (ACE) | |
Renin |
Question 3 |
A decrease in blood flow to an interlobular artery could result from stenosis of which artery?
Arcuate artery | |
Afferent arteriole | |
Efferent arteriole | |
Vasa recta |
Question 4 |
Outline, in sequence, the blood supply for the kidney beginning from renal artery to venous supply
Renal artery, segmental artery, interlobar artery, arcuate artery, interlobular artery, afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries/vasa recta. | |
Renal artery, interlobular artery, interlobar artery, arcuate artery, segmental artery, afferent arteriole, glomerulus, peritubular capillaries/vasa recta efferent arteriole | |
Renal artery, segmental artery, interlobular artery, arcuate artery, interlobar artery, afferent arteriole, glomerulus, peritubular capillaries/vasa recta, efferent arteriole | |
Renal artery, segmental artery, interlobular artery, arcuate artery, interlobular artery, afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries/vasa recta. |
Question 5 |
Which of the following is not a function of the kidney?
Calcium homeostasis | |
Regulation of ECF sodium | |
Synthesis of ADH | |
Regulation of body fluid volume |
Question 6 |
How is urinary excretion rate altered by a high reabsorption rate?
It is increased | |
It is decreased | |
It does not alter urinary excretion rate | |
It is not part of the equation |
Question 7 |
A patient has nephrogenic diabetes insipidus. Which part of the uriniferous tubule is most likely to be affected?
Proximal convoluted tubule | |
Collecting duct | |
Thick ascending loop of Henle | |
Thick descending loop of Henle |
Question 8 |
How would the basement membrane of the glomerular filtration barrier prevent the passage of albumin?
By repulsion of albumin’s positive charge | |
By having fenestrations smaller than the size of albumin | |
By having fenestrations of different shape to albumin | |
By repulsion of albumin’s negative charge
|
Question 9 |
Inulin is one of the most accurate measures of urinary excretion rate, why is this?
It is filtered and partially reabsorbed so it accurately reflects what happens to substances in the filtrate | |
It is filtered only, so its concentration in the urine is proportionate to the amount in the blood | |
It is filtered and secreted, accurately representing how the kidney processes multiple substances as a whole | |
It is filtered and completely reabsorbed, reflecting how glucose is handled by the kidney |
Question 10 |
What are the main ions contributing to the concentration gradient in extracellular fluid?
Calcium and bicarbonate | |
Potassium, phosphate and inorganic anions | |
Sodium and potassium | |
Sodium and chloride |
