Chemistry QUESTION #7109

Consider the following reduction potentials:

$Zn^{2+} + 2e^{-} \rightarrow Zn(s)$; $E^{0} = -0.76\text{ V}$
$Ca^{2+} + 2e^{-} \rightarrow Ca(s)$; $E^{0} = -2.87\text{ V}$
$Mg^{2+} + 2e^{-} \rightarrow Mg(s)$; $E^{0} = -2.36\text{ V}$
$Ni^{2+} + 2e^{-} \rightarrow Ni(s)$; $E^{0} = -0.25\text{ V}$

What is the correct increasing order of the reducing power of these metals?

$Ca < Zn < Mg < Ni$
$Ni < Zn < Mg < Ca$✔️
$Zn < Mg < Ni < Ca$
$Ca < Mg < Zn < Ni$

Correct Answer Logic:

Reducing power is inversely proportional to the standard reduction potential ($E^0$). The more negative the $E^0$ value, the stronger the reducing agent. Comparing the values: $Ni$ (-0.25) is the weakest, followed by $Zn$ (-0.76), then $Mg$ (-2.36), and $Ca$ (-2.87) is the strongest.

Physics QUESTION #7341

Question 5

A particle has initial velocity $(2\hat{i}+3\hat{j})$ and constant acceleration $(0.3\hat{i}+0.2\hat{j})$. Its speed after 10 s is:

5 units
9 units
$9\sqrt{2}$ units
$5\sqrt{2}$ units✔️

Correct Answer Logic:

$\vec{v} = (2+0.3\times10)\hat{i} + (3+0.2\times10)\hat{j} = 5\hat{i}+5\hat{j}$

Speed $= \sqrt{25+25} = \sqrt{50} = \mathbf{5\sqrt{2}}$ units

Agronomy QUESTION #2036

Question 6

Physiological maturity in cereal crops is best identified by:

The date 30 days after heading
Formation of the black layer at the base of the grain (in maize) or when grain moisture reaches 30–35% and maximum dry weight is achieved✔️
When the entire crop canopy turns golden yellow
When combine harvester settings indicate optimum grain moisture

Correct Answer Logic:

Physiological maturity marks the cessation of dry matter accumulation in the grain. In maize it is identified by the black layer (abscission layer) at the kernel base. In wheat/rice, grain moisture of 30–35% at maximum dry weight is the indicator — harvesting before this causes yield loss; after causes field losses.

Question 7

اہلِ زبان کی مخصوص بول چال میں جب لفظ اپنے حقیقی معنوں میں استعمال ہوں تو قواعد کی رو سے اسے کیا کہلاتے ہیں؟

مصدر
فعل
محاورہ
روزمرہ✔️

Correct Answer Logic:

روزمرہ وہ الفاظ، تراکیب یا جملے ہیں جو اہلِ زبان اپنی عام بول چال میں حقیقی یا مستعمل معنوں میں روزانہ استعمال کرتے ہیں۔ محاورہ اس سے مختلف ہے — محاورے میں الفاظ اپنے لغوی معنوں میں نہیں بلکہ مجازی معنوں میں استعمال ہوتے ہیں۔

The Constitution of Pakistan QUESTION #9367

Question 8

Article 25A imposes a duty on the State to provide free and compulsory education. What is the age range for children covered by this Article?

Three to fourteen years
Five to sixteen years✔️
Six to fourteen years
Four to eighteen years

Correct Answer Logic:

Article 25A, inserted by the 18th Amendment 2010, provides: 'The State shall provide free and compulsory education to all children of the age of five to sixteen years.' This is a constitutional right to education, making it enforceable, unlike the Principles of Policy.

Law QUESTION #9486

Question 9

A decree-holder A wishes to attach a sum of Rs. 500,000 kept in a bank account belonging to the judgment-debtor B, which was earned by B as salary and deposited over time. B argues that salary is exempt from attachment. Can the bank balance representing accumulated salary be attached?

Yes; once salary has been received and deposited in a bank account, it loses its character as salary and becomes an ordinary debt recoverable from the bank, which is attachable✔️
Yes; but only with the permission of the State Bank of Pakistan
No; bank accounts can never be attached in execution
No; salary retains its exempt character even after being deposited in a bank

Correct Answer Logic:

The exemption under Section 60(1)(i) CPC applies to salary before and until it is actually payable; once salary has been paid and deposited in a bank, it is converted into a debt due from the bank and loses its exempt character, becoming attachable in execution.

Nursing QUESTION #9254

Question 10

A nurse assesses a 6-month-old infant. Which developmental milestone is EXPECTED and NORMAL at this age according to Denver Developmental Screening?

Walks alone
Says 2–3 word sentences
Sits with support and transfers objects hand to hand✔️
Pincer grasp and stands holding furniture

Correct Answer Logic:

Denver Developmental Screening Test (DDST-II) milestones at 6 months:

Domain	Expected at 6 Months
Gross Motor	Sits with support, rolls over (front to back), bears weight on legs
Fine Motor	Transfers objects hand to hand, reaches for objects, raking grasp
Language	Babbles, monosyllables (ba, da, ma), laughs, squeals
Personal-Social	Recognizes faces, smiles spontaneously, feeds self cracker

Key milestones timeline:

3 months: Head control, social smile
6 months: Sits with support, transfers objects ✓
9 months: Stands holding furniture, pincer grasp developing
12 months: Walks with support, 1–2 words
18 months: Walks alone, 10+ words
24 months: 2–3 word sentences, runs

Red flags at 6 months: No head control, no social smile, not reaching for objects — warrant immediate developmental evaluation.

Nursing QUESTION #9286

Question 12

In a patient with increased intracranial pressure (IICP), which nursing position is most appropriate?

Trendelenburg (head-down 15–30 degrees)
Head of bed elevated 30–45 degrees, neck in neutral alignment✔️
Prone position
Left lateral position

Correct Answer Logic:

Nursing management of Increased ICP — positioning is critical:

Head of bed 30–45 degrees: Promotes venous drainage from the brain via jugular veins, reducing ICP
Neutral neck alignment: Prevents jugular vein compression — neck flexion or rotation can obstruct venous outflow and raise ICP significantly

Actions to AVOID in IICP:

Trendelenburg position (increases ICP)
Valsalva maneuver (straining, coughing)
Hip flexion > 90 degrees
Clustering of nursing activities
Hypercapnia (PaCO₂ > 45 mmHg causes cerebral vasodilation → increases ICP)

The Monro-Kellie doctrine states: ICP = Brain volume + Blood volume + CSF volume. Interventions target reducing any of these components.

Journalism / Mass Communication QUESTION #6420

Question 14

According to the textbook, what is the MOST accurate statement about the first Urdu daily newspaper and when it was started?

Zameendar was the first Urdu daily, started in 1903 from Lahore
Urdu Guide was the first Urdu daily newspaper, started by Maulvi Kabeeruddin from Kolkata in 1858✔️
Kohinoor was the first Urdu daily, started by Munshi Harsukh Rai in 1850
Jam-e-Jahan Numa was the first Urdu daily, started in 1822

Correct Answer Logic:

The textbook provides a detailed timeline of early Urdu journalism:

1822: Jam-e-Jahan Numa — first Persian weekly published, sometimes in Urdu, sometimes in Persian — a weekly, not a daily
14 January 1850: Kohinoor — started by Munshi Harsukh Rai as a weekly with circulation of 350 (the largest of its time)
1858: Urdu Guide — started by Maulvi Kabeeruddin from Kolkata — this was the FIRST Urdu daily newspaper
Same year (1858): Roznamcha-e-Punjab started from Lahore as the second daily
1903: Zameendar started from Lahore — best newspaper of its time, first to use news agencies, circulation of 30,000, supported independence movement

Students commonly confuse the first publication in Urdu (Jam-e-Jahan Numa, 1822) with the first Urdu daily (Urdu Guide, 1858).

Nursing QUESTION #9238

Question 17

A patient develops Ventricular Fibrillation (VF) in the ICU. According to ACLS 2020 guidelines, what is the CORRECT sequence of management?

Defibrillate 360J → Amiodarone 300mg → CPR 2 min → Epinephrine 1mg
CPR 2 min → Defibrillate 200J biphasic → Epinephrine 1mg → CPR 2 min → Amiodarone if VF persists
Defibrillate immediately → CPR 2 min → Epinephrine 1mg IV → CPR 2 min → Amiodarone 300mg if VF/pVT persists✔️
Epinephrine 1mg → CPR 5 min → Defibrillate 360J → Amiodarone 150mg

Correct Answer Logic:

Correct Answer: C — ACLS VF/pulseless VT Algorithm (2020)

ACLS Shockable Rhythm (VF/pVT) Algorithm:

Defibrillate immediately (biphasic 120–200J; monophasic 360J)
CPR 2 minutes (high-quality: 100–120 compressions/min, depth $5-6 \text{ cm}$)
Check rhythm — if still VF/pVT:
Epinephrine 1 mg IV/IO every 3–5 minutes
Defibrillate again
CPR 2 minutes
If VF/pVT persists: Amiodarone 300 mg IV (second dose: 150 mg) OR Lidocaine

Key points:

Minimize interruptions in CPR (pause $< 10$ seconds for shocks)
Treat reversible causes: 5 H's and 5 T's (Hypoxia, Hypovolemia, H$^+$ acidosis, Hypo/Hyperkalemia, Hypothermia; Tension pneumothorax, Tamponade, Toxins, Thrombosis-PE, Thrombosis-coronary)
Epinephrine: given after first or second defibrillation attempt, then every 3–5 min
