MBBS QUESTION #10243
Question 3841
A patient in early hypovolemic shock shows a fall in cardiac output. Baroreceptor reflex activation (from the carotid sinus and aortic arch) in response to this fall in blood pressure produces which autonomic response?
  • Decreased sympathetic outflow with increased vagal tone, producing bradycardia and vasodilation
  • Increased sympathetic outflow with decreased vagal tone, producing tachycardia and peripheral vasoconstrictionβœ”οΈ
  • No significant change in autonomic outflow
  • Selective activation of parasympathetic vasodilator fibers to skeletal muscle only
Correct Answer Logic:
A fall in arterial pressure reduces baroreceptor firing, which disinhibits the vasomotor center, resulting in increased sympathetic outflow (tachycardia, increased contractility, arteriolar and venous vasoconstriction) and reduced vagal tone β€” the compensatory response that helps maintain perfusion pressure in early hemorrhagic shock.

Physics QUESTION #7093
Question 3842
A particle starts at $(2, 4)$ at $t=0$ with velocity $(5\hat{i}+4\hat{j})$. Constant acceleration is $(4\hat{i}+4\hat{j})$. Find its distance from the origin at $t=2\text{ s}$.
  • 15 m
  • $20\sqrt{2}\text{ m}$βœ”οΈ
  • 5 m
  • $10\sqrt{2}\text{ m}$
Correct Answer Logic:

Using $\vec{s} = \vec{r}_0 + \vec{u}t + \frac{1}{2}\vec{a}t^2$:

  • $x = 2 + 5(2) + \frac{1}{2}(4)(2^2) = 2 + 10 + 8 = 20$
  • $y = 4 + 4(2) + \frac{1}{2}(4)(2^2) = 4 + 8 + 8 = 20$
  • Distance from origin $D = \sqrt{20^2 + 20^2} = 20\sqrt{2}\text{ m}$.

Professional QUESTION #1822
Question 3844
Section 2(d) defines 'pay' as the amount drawn monthly by a civil servant. Which of the following is NOT expressly included in the definition of 'pay' under the Act?
  • Technical pay
  • Special pay
  • Daily allowanceβœ”οΈ
  • Personal pay
Correct Answer Logic:
Section 2(d) defines pay to include technical pay, special pay, personal pay, and any other emoluments declared by the prescribed authority to be pay. Daily allowance is a separate entitlement and is not included within the statutory definition of 'pay' under the Act.

Nursing QUESTION #9134
Question 3845
A gravida 2 para 1 at 39 weeks presents in active labor. Vaginal examination reveals: cervix 8 cm dilated, fully effaced, vertex at +1 station, occiput posterior position. After 2 hours, no progress is noted. What is the MOST likely cause of arrest of descent?
  • Cephalopelvic disproportion (CPD)
  • Occiput Posterior (OP) position causing malrotationβœ”οΈ
  • Inadequate uterine contractions (hypotonic labor)
  • Cord prolapse
Correct Answer Logic:

Persistent Occiput Posterior (POP) position is a common cause of prolonged second stage and arrest of descent. In OP position:

  • The fetal head presents with a larger diameter to the pelvis: occipito-frontal diameter \(\approx 11.5\,\text{cm}\) vs. sub-occipito-bregmatic \(9.5\,\text{cm}\) in OA
  • Internal rotation from OP to OA requires \(135Β°\) rotation (vs. \(90Β°\) from OT, \(45Β°\) from OA)
  • Causes: anthropoid/android pelvis, deflexed head

Management options:

  • Manual rotation to OA (Barton's maneuver)
  • Expectant management if maternal/fetal condition good
  • Instrumental delivery: forceps (Kielland's rotational forceps) or rotational vacuum
  • Cesarean section if rotation fails or fetal distress

CPD is less likely in a multigravida who delivered previously without CPD. Hypotonic labor would show weak contractions on partograph/CTG.

Security Measures to Maintain Law and Order QUESTION #899
Question 3846
Which section of the ASF Act 1975 provides the legal basis for the "Maintenance of Law and Order" within aerodromes?
  • Preamble & Section 6βœ”οΈ
  • Section 3
  • Section 11
  • Section 13
Correct Answer Logic:
The Preamble sets the intent, and Section 6(1)(d) specifically mandates the Force to maintain law and order within airports.

MBBS QUESTION #10319
Question 3847
A competitive enzyme inhibitor, which binds reversibly at the enzyme's active site, characteristically produces which kinetic pattern?
  • Increased apparent $K_m$ with unchanged $V_{max}$, since the inhibitory effect can be overcome by sufficiently increasing substrate concentrationβœ”οΈ
  • Decreased $V_{max}$ with unchanged $K_m$
  • Decreased both $K_m$ and $V_{max}$
  • Binding exclusively to the enzyme-substrate complex, never to free enzyme
Correct Answer Logic:
Because a competitive inhibitor competes directly with substrate for the same active site, raising substrate concentration can outcompete the inhibitor, restoring $V_{max}$ at sufficiently high [S] β€” but more substrate is now needed to reach half-maximal velocity, raising the apparent $K_m$.

  • Tourist
  • Pilgrimβœ”οΈ

A 'Pilgrim' is a person who journeys to a sacred place for religious reasons. A Tourist travels for leisure; a Nomad has no fixed home; a Wanderer roams without specific purpose.

Physics QUESTION #7343
Question 3853

A projectile is launched from the ground with initial velocity $\vec{u} = u_0\hat{i} + v_0\hat{j}$. Gravity acts in the $-y$ direction. The maximum displacement in the $x$-direction is:
  • $\dfrac{u_0^2}{2g}$
  • $\dfrac{2u_0 v_0}{g}$βœ”οΈ
  • $\dfrac{v_0^2}{2g}$
  • $\dfrac{4u_0 v_0}{g}$
Correct Answer Logic:

Time of flight $= \dfrac{2v_0}{g}$ (time for vertical displacement to return to zero).

Horizontal range $= u_0 \times \dfrac{2v_0}{g} = \mathbf{\dfrac{2u_0 v_0}{g}}$

Chemistry QUESTION #4361
Question 3856
Which one of the following has higher vapour pressure?
  • Acetone
  • Acetaldehyde
  • Isopentaneβœ”οΈ
  • Benzene
Correct Answer Logic:
Vapour pressure depends on intermolecular forces β€” weaker forces mean higher vapour pressure. Isopentane ($C_5H_{12}$) has only weak London dispersion forces (low boiling point: $28Β°C$), giving it the highest vapour pressure among the options.

Aptitude QUESTION #10919
Question 3859
In a certain building plan, the North direction is towards the bottom of the page. A room is to the South-East of the main hall. In which direction on the page does the room appear?
  • Top-leftβœ”οΈ
  • Top-right
  • Bottom-left
  • Bottom-right
Correct Answer Logic:

If North is at the bottom of the page, then all compass directions are inverted:

  • North β†’ bottom
  • South β†’ top
  • East β†’ left
  • West β†’ right

South-East in real terms = top + left on this rotated page = Top-left.

This type of question tests your ability to mentally rotate a reference frame β€” a critical skill in architectural plan reading.
