Free Sneak Peek

Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

Q1
What is the Net Filtration Pressure (NFP) driving ultrafiltration across the glomerular membrane in Bowman's capsule?
बोमन कैप्सूल में ग्लोमेरुलर झिल्ली में अल्ट्राफिल्ट्रेशन चलाने वाला शुद्ध निस्पंदन दबाव (एनएफपी) क्या है?
A
\(NFP = 60 + 32 + 18 = 110 mm Hg\)एनएफपी = 60 + 32 + 18 = 110 मिमी एचजी
B
\(NFP = 0 mm Hg\)एनएफपी = 0 मिमी एचजी
C
\(NFP = -25 mm Hg\)एनएफपी = -25 मिमी एचजी
D
\(NFP = Glomerular Hydrostatic Pressure (GHP ~60 mm Hg) - [Blood Colloid Osmotic Pressure (BCOP ~32 mm Hg) + Capsular Hydrostatic Pressure (CHP ~18 mm Hg)] ≈ +10 mm Hg\)एनएफपी = ग्लोमेरुलर हाइड्रोस्टैटिक दबाव (जीएचपी ~60 मिमी एचजी) - [रक्त कोलाइड आसमाटिक दबाव (बीसीओपी ~32 मिमी एचजी) + कैप्सुलर हाइड्रोस्टैटिक दबाव (सीएचपी ~18 मिमी एचजी)] ≈ +10 मिमी एचजी
Correct Answer: Option D
Explanation:
\(NFP = GHP - (BCOP + CHP) = 60 - (32 + 18) = +10 mm Hg. This positive net pressure forces water and crystalloids through the three-layered filtration barrier into Bowman's space.\)
एनएफपी = जीएचपी - (बीसीओपी + सीएचपी) = 60 - (32 + 18) = +10 मिमी एचजी। यह सकारात्मक शुद्ध दबाव पानी और क्रिस्टलॉयड को तीन-परत निस्पंदन अवरोध के माध्यम से बोमन के स्थान में भेजता है।
Q2
Assertion (A): Human kidneys can produce urine nearly four times more concentrated (1200 mOsmol/L) than the initial glomerular filtrate (300 mOsmol/L). Reason (R): The hyperosmolarity of the inner renal medullary interstitium is maintained by the counter-current multiplication between the Henle's loop and Vasa Recta, and by urea recycling from collecting duct to thin ascending limb.
दावा (ए): मानव गुर्दे प्रारंभिक ग्लोमेरुलर फ़िल्टरेट (300 mOsmol/L) की तुलना में लगभग चार गुना अधिक केंद्रित (1200 mOsmol/L) मूत्र का उत्पादन कर सकते हैं। कारण (आर): आंतरिक रीनल मेडुलरी इंटरस्टिटियम की हाइपरोस्मोलैरिटी हेनले लूप और वासा रेक्टा के बीच काउंटर-करंट गुणन द्वारा और एकत्रित वाहिनी से पतली आरोही अंग तक यूरिया रीसाइक्लिंग द्वारा बनाए रखी जाती है।
A
Both (A) and (R) are true but (R) is not the correct explanation of (A)(ए) और (आर) दोनों सत्य हैं लेकिन (आर) (ए)
B
Both (A) and (R) are true and (R) is the correct explanation of (A)का सही स्पष्टीकरण नहीं है (ए) और (आर) दोनों सत्य हैं और (आर) (ए)
C
(A) is true but (R) is falseका सही स्पष्टीकरण है (ए) सच है लेकिन (आर) गलत है
D
(A) is false but (R) is true(ए) गलत है लेकिन (आर) सच है
Correct Answer: Option B
Explanation:
The counter-current multiplier system (NaCl transport from ascending limb + urea recycling from collecting duct) elevates medullary osmolarity to 1200 mOsm/L, concentrating urine up to 4×.
काउंटर-करंट मल्टीप्लायर सिस्टम (आरोही अंग से NaCl ट्रांसपोर्ट + कलेक्टिंग डक्ट से यूरिया रीसाइक्लिंग) मेडुलरी ऑस्मोलैरिटी को 1200 mOsm/L तक बढ़ा देता है, जिससे मूत्र 4× तक केंद्रित हो जाता है।

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Focused chapter-wise CBT practice builds the speed, mental stamina, and analytical discipline required to ace CUET, JEE Main, NEET UG, NDA, CA Foundation, and College Entrance Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
