Which of the following are the correct statements? (Select all that apply)
Renal agenesis: failure of an organ (renal) to develop
Renal hypoplasia: failure of kidney to develop to normal size and contains fewer renal lobes
Renal dysgenesis: failure of an organ (kidney to develop normally)
Renal dysgenesis: failure of an organ (kidney) to develop
Correct Answer : A,B,C
A. Renal agenesis: failure of an organ (renal) to develop: Renal agenesis is the complete absence of one or both kidneys due to failure of development during fetal life. Bilateral agenesis is often fatal, while unilateral agenesis can be asymptomatic if the remaining kidney functions well.
B. Renal hypoplasia: failure of kidney to develop to normal size and contains fewer renal lobes: In renal hypoplasia, the kidney is structurally normal but smaller than average and contains fewer nephrons or lobes. This congenital condition may be unilateral and asymptomatic or bilateral and lead to renal insufficiency.
C. Renal dysgenesis: failure of an organ (kidney) to develop normally: Renal dysgenesis refers to abnormal development of the kidney structure, resulting in malformations that can impair function. It often involves malformed or nonfunctional renal tissue.
D. Renal dysgenesis: failure of an organ (kidney) to develop: This description better defines renal agenesis rather than dysgenesis, which implies abnormal rather than absent development.

Correct Answer is A
Explanation
A. The patient requires painful stimuli to elicit a response and has no purposeful movement: This indicates a severe decrease in consciousness where the patient is minimally responsive, unable to respond to verbal stimuli, and shows no purposeful movement. It reflects significant brain dysfunction and is often seen in severe brain injury or coma.
B. The patient is drowsy but responds to verbal stimuli appropriately: This describes mild to moderate impairment of consciousness, where the patient is lethargic but still able to respond meaningfully to verbal commands, indicating a less severe condition.
C. The patient responds to commands but is slow to do so: A slowed response suggests some cognitive or neurological impairment but not a severe decrease in consciousness. The patient remains alert enough to follow instructions, albeit slowly.
D. The patient can follow simple commands like "open your eyes": This shows the patient is conscious and able to interact, reflecting a mild or normal level of consciousness rather than severe impairment.
Correct Answer is D
Explanation
A. Azotemia: Azotemia, or elevated blood urea nitrogen (BUN) and creatinine levels, is a common feature of glomerulonephritis due to reduced kidney filtration capacity and accumulation of nitrogenous wastes in the blood.
B. Hematuria with red cell casts: Hematuria with red blood cell casts is a classic hallmark of glomerulonephritis, indicating glomerular bleeding and inflammation. These casts are formed in the nephron and reflect active glomerular injury.
C. Oliguria and hypertension: Both are characteristic findings in glomerulonephritis. Oliguria results from impaired filtration, while hypertension develops due to fluid retention and activation of the renin-angiotensin-aldosterone system.
D. An increased glomerular filtration rate (GFR) of >100: Glomerulonephritis typically leads to a decreased GFR, not an increase. Inflammation and damage to the glomeruli impair the kidneys' ability to filter blood effectively, resulting in reduced GFR and waste accumulation.
