Nursing QUESTION #9134

Question 2522

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 malrotation✔️
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 $135°$ rotation (vs. $90°$ from OT, $45°$ 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.

Accounting & Finance QUESTION #1228

Question 2523

The discount rate at which two projects have identical _________ is referred to as Fisher's rate of intersection.

Present values
Net present values✔️
IRRs
Profitability indexes

Correct Answer Logic:

Fisher's rate of intersection (or Fisher's rate) is the discount rate at which the NPVs of two mutually exclusive projects are equal — the crossover rate. At this rate, both projects have identical Net Present Values. Below this rate, one project is preferred; above it, the other is preferred. It is used to resolve conflicts between NPV and IRR rankings.

Law QUESTION #9501

Question 2524

The trial Court in a civil suit, after full trial, passes a judgment. The losing party B files an appeal. The appellate Court, without conducting a hearing on merits, reverses the trial Court's decree only because it disagrees with the trial Court's findings of fact, without identifying any specific perversity or misreading of evidence. Is this valid appellate exercise?

Yes; an appellate Court can freely re-appreciate evidence
No; an appellate Court can reverse only on questions of law
Yes; a first appeal is a rehearing on facts and law
No; while an appellate Court can re-appreciate evidence, reversal requires more than mere disagreement; the appellate Court must assign reasons for disagreeing with the trial Court's findings and identify how the evidence was misread or ignored✔️

Correct Answer Logic:

The CPC and settled principles of appellate jurisprudence require that a first appellate Court, while having jurisdiction to reassess evidence, must not substitute its own findings for those of the trial Court without adequate reasons. Reversal on facts requires the appellate Court to demonstrate perversity, misreading, or improper appreciation of evidence, not mere disagreement.

Chemistry QUESTION #4374

Question 2526

Correct arrangement of orbital according to size of hybridized orbitals:

$sp > sp^2 > sp^3$
$sp^3 > sp > sp^2$
$sp^2 > sp > sp^3$
$sp^3 > sp^2 > sp$✔️

Correct Answer Logic:

The size of hybridized orbitals increases with increasing $sp^3$ character: $sp^3 > sp^2 > sp$. This is because more p-character means more diffuse, larger orbitals, and $sp^3$ has the most p-character (75%).

Question 2529

Motor vehicles costing $530,000 were depreciated at 10% straight-line instead of the correct 25%. After incorrect entries: Motor vehicles at cost $530,000; Provision for depreciation $53,000. Which journal entries will correct the error?

Debit: Provision for depreciation $79,500 | Credit: Statement of profit or loss $79,500
Debit: Provision for depreciation $132,500 | Credit: Statement of profit or loss $132,500
Debit: Statement of profit or loss $79,500 | Credit: Provision for depreciation $79,500✔️
Debit: Statement of profit or loss $132,500 | Credit: Provision for depreciation $132,500

Correct Answer Logic:

Option C is correct.

Correct depreciation = $530,000 × 25% = $132,500

Already charged = $530,000 × 10% = $53,000

Additional needed = $132,500 − $53,000 = $79,500

Entry: Debit Statement of profit or loss $79,500 | Credit Provision for depreciation $79,500

Physics QUESTION #7030

Question 2532

A locomotive travels along a straight path at a constant speed of $20\text{ ms}^{-1}$ while sounding its whistle at $1000\text{ Hz}$. Calculate the approximate percentage change in frequency perceived by a stationary observer as the locomotive passes them. (Speed of sound $= 320\text{ ms}^{-1}$).

$6\%$
$12\%$✔️
$18\%$
$24\%$

Correct Answer Logic:

Using the Doppler effect: Frequency approaching $f_{app} = f(\frac{v}{v - v_s}) = 1000(\frac{320}{300}) \approx 1066.6\text{ Hz}$. Frequency receding $f_{rec} = f(\frac{v}{v + v_s}) = 1000(\frac{320}{340}) \approx 941.1\text{ Hz}$. The change is $\approx 125.5\text{ Hz}$. Percentage change relative to the source is $(\frac{125.5}{1000}) \times 100 \approx 12.5\%$.

Physics QUESTION #1025

Question 2533

The intensity of transmitted light when a polaroid sheet is placed between two crossed polaroids at $22.5°$ from the polarization axis of one of them is ($I_0$ = intensity after first polaroid):

$\dfrac{I_0}{8}$✔️
$\dfrac{I_0}{16}$
$\dfrac{I_0}{2}$
$\dfrac{I_0}{4}$

Correct Answer Logic:

After first polaroid: $I_0$. After middle polaroid (at $22.5°$): $I_1 = I_0\cos^2 22.5°$. The remaining angle to the second crossed polaroid is $90°-22.5°=67.5°$. After second: $I = I_1\cos^2 67.5° = I_0\cos^2 22.5°\cos^2 67.5°$. Using $\cos22.5°\cos67.5° = \frac{1}{2}\sin45° = \frac{\sqrt{2}}{4}$: $I = I_0\cdot\frac{1}{4}\cdot\sin^2 45° = I_0\cdot\frac{1}{4}\cdot\frac{1}{2} = \frac{I_0}{8}$.

Electrical Engineering QUESTION #2164

Question 2536

A BJT common-emitter amplifier has $\beta = 100$, $R_C = 4\,\text{k}\Omega$, and $I_{C,Q} = 1\,\text{mA}$. The small-signal voltage gain $A_v$ (neglecting $r_o$) is:

$-154$✔️
$+154$
$-400$
$-100$

Correct Answer Logic:

$g_m = I_C/V_T = 1\,\text{mA}/26\,\text{mV} \approx 38.5\,\text{mS}$. $A_v = -g_m R_C = -38.5\,\text{mS} \times 4\,\text{k}\Omega \approx -154$.

Dairy Food Science and Technology QUESTION #5960

Question 2537

Which type of homogenizer is most commonly used in the dairy industry?

Ultrasonic homogenizer
High-pressure (valve) homogenizer ($2000\text{–}2500\;\text{psi}$)✔️
Microfluidizer
Membrane emulsification homogenizer

Correct Answer Logic:

High-pressure homogenizers (HPH) are the industry standard. Milk is forced through a narrow adjustable valve at $2000\text{–}2500\;\text{psi}$. The pressure drop, turbulence, cavitation, and shear forces reduce fat globule size from $1\text{–}10\;\mu\text{m}$ to $<0.5\text{–}2\;\mu\text{m}$.
