Nursing QUESTION #9136

Question 68

A 28-year-old woman at 12 weeks gestation is found to have blood group O Rh-negative with no antibodies. Her husband is Rh-positive. What is the MOST important preventive intervention during this pregnancy?

Administer Anti-D immunoglobulin 300 mcg IM at 28 weeks only
Administer Anti-D immunoglobulin at 28 weeks, and within 72 hours of any sensitizing event and after delivery✔️
No intervention needed as antibodies are absent currently
Monthly blood transfusion to maintain maternal iron levels

Correct Answer Logic:

Rhesus (Rh) Isoimmunization Prevention is critical in Rh-negative pregnant women:

Sensitizing events requiring Anti-D administration:

Amniocentesis, CVS, cordocentesis
Antepartum hemorrhage (APH)
External cephalic version (ECV)
Abdominal trauma
Miscarriage/termination
Ectopic pregnancy
Delivery (within 72 hours)

Routine prophylaxis: Anti-D 300 mcg IM at 28 weeks (and some protocols: 28 + 34 weeks).

Dose:

First trimester sensitizing event: $250\,\text{IU}$ (50 mcg)
After 20 weeks / delivery: $500\,\text{IU}$ (100 mcg) or $300\,\text{mcg}$ (1500 IU)

The Kleihauer-Betke test estimates fetal-maternal hemorrhage volume to calculate additional Anti-D dose needed:

\[\text{Additional dose} = \frac{\% \text{fetal cells} \times \text{maternal blood volume}}{30} \times 300\,\mu\text{g}\]

Without prophylaxis, risk of sensitization after delivery = 16%. With Anti-D = reduced to <0.1%.

Question 69

The minimum required protein content of yoghurt in most standards is typically achieved by:

Adding sodium caseinate
Fortifying with skim milk powder (SMP) or whey protein concentrate (WPC) to increase total MSNF✔️
Increasing fermentation time
Reducing the fat content

Correct Answer Logic:

To ensure proper gel formation and meet protein standards ($\geq 2.7\text{–}3.2\%$ protein), milk is often standardized by adding SMP or WPC to increase total MSNF. This also improves texture, body, and reduces syneresis.

Maths QUESTION #7655

Question 72

If $a : b : c = 3 : 4 : 7$, then the ratio $(a+b+c) : x$ is equal to:

$2 : 1$
$14 : 3$
$7 : 2$
None of these✔️

Correct Answer Logic:

Given $a : b : c = 3 : 4 : 7$. Let $a = 3k$, $b = 4k$, $c = 7k$. Then $a + b + c = 3k + 4k + 7k = 14k$. The question asks for ratio with 'x' which is not defined in the original problem, making this question incomplete. The answer would be 'None of these' due to insufficient information.

Question 74

In project appraisal, if Internal Rate of Return (IRR) is 8% and discount rate is 10%, the project is:

Economically viable
Economically not viable✔️
Break-even
Requires subsidy

Correct Answer Logic:

IRR is the discount rate where NPV = 0. For viability, IRR must exceed the opportunity cost of capital (discount rate). IRR (8%) < discount rate (10%) means project returns less than alternative investments—economically unviable without considering non-monetary benefits.

Question 77

A regular hexagon is divided into 6 equilateral triangles. If the hexagon has an area of \(54\sqrt{3}\ \text{cm}^2\, what is the side length of the hexagon?

6 cm✔️
3 cm
9 cm
4 cm

Correct Answer Logic:

Area of regular hexagon with side \(s\: \(A = \dfrac{3\sqrt{3}}{2}s^2\

Setting equal: \(\dfrac{3\sqrt{3}}{2}s^2 = 54\sqrt{3}\

\(s^2 = \dfrac{54\sqrt{3} \times 2}{3\sqrt{3}} = \dfrac{108}{3} = 36\

\(s = 6\ \text{cm}\

Verification: \(\dfrac{3\sqrt{3}}{2} \times 36 = 54\sqrt{3}\ ✓

Dairy Food Science and Technology QUESTION #5955

Question 78

Which of the following is NOT a function of water in ice cream?

Acts as solvent for sugar, minerals, and other water-soluble components
Participates in the freezing process forming ice crystals that contribute to texture ($40\text{–}70\%$ of water frozen at $-14^{\circ}\text{C}$)
Acts as an emulsifying agent for fat globules✔️
Determines the final ice crystal size distribution and texture of ice cream

Correct Answer Logic:

Water in ice cream dissolves sugars, proteins, and minerals, and freezes to form ice crystals ($40\text{–}70\%$ of water frozen at serving temperature $-14^{\circ}\text{C}$). Water does NOT act as an emulsifier — that function is performed by emulsifiers (lecithin, mono/diglycerides) and proteins.

Biology Zoology Botany QUESTION #1353

Question 79

All of the following statements regarding 'lung ventilation' and 'gas exchange' in birds are TRUE EXCEPT:

Abdominal and thoracic air sacs are compressed by body muscles to move air through the respiratory system
Gas exchange occurs in blind-ending sacs called alveoli✔️
Two respiratory cycles are required to move a volume of air through the respiratory system
None of these

Correct Answer Logic:

Statement (B) is FALSE for birds. In birds, gas exchange does NOT occur in blind-ending alveoli (as in mammals) but in microscopic tubes called parabronchi, where air flows unidirectionally. This allows continuous, highly efficient gas exchange in both inhalation and exhalation. Statements (A) and (C) are true — air sacs act as bellows and two breath cycles are needed to move air through the entire system.

Chemistry QUESTION #7391

Question 80

The liquefied metal that expands on solidification is:

Ga✔️
Al
Zn
Cu

Correct Answer Logic:

Gallium (Ga) is one of the few substances (like water and bismuth) that expands on solidification. This is due to its unusual crystal structure in the solid state, where Ga–Ga covalent bonds result in a less dense solid than the liquid. Gallium has a very low melting point (29.76°C) and is liquid at or slightly above room temperature.
