Nursing QUESTION #9271

Question 7982

A 2-year-old child accidentally ingests an unknown household substance and is brought to the emergency. The child is drowsy, has pinpoint pupils, and respiratory rate of 6/min. The MOST appropriate antidote is:

Atropine IV
Naloxone 0.1 mg/kg IV/IM✔️
N-Acetylcysteine
Flumazenil

Correct Answer Logic:

The clinical triad of pinpoint pupils (miosis) + drowsiness/coma + respiratory depression is the classic presentation of Opioid Poisoning.

Opioid toxidrome:

CNS depression (lethargy → coma)
Respiratory depression (RR <12/min — most dangerous)
Miosis (pinpoint pupils)
Bradycardia, hypotension

Antidote: Naloxone (Narcan) — opioid receptor antagonist

\[\text{Dose: } 0.1\,\text{mg/kg}\,\text{IV/IM/intranasal (max 2 mg per dose)}\]

Onset IV: 1–2 minutes
Duration: 30–90 minutes (shorter than most opioids — may need repeat doses or infusion)
Monitor for re-narcotization

Other antidotes (important for nurses):

Poison	Antidote
Organophosphates	Atropine + Pralidoxime
Paracetamol	N-Acetylcysteine
Benzodiazepines	Flumazenil
Iron	Desferrioxamine
Lead	DMSA (Succimer), EDTA
Carbon monoxide	100% O₂ / Hyperbaric O₂

Quantitative Reasoning QUESTION #8127

Question 7984

Authoritarian managers often fail to recognize a key reason for low conflict in democratically run groups: allowing even a small degree of tolerance for dissent frequently prevents _______.

demur
schism✔️
cooperation
compliance

Correct Answer Logic:

The logic is: a little tolerance for disagreement prevents serious conflict. Schism means a major split or division — preventing schism is the natural payoff of allowing minor dissent to be voiced safely. 'Demur' means objecting, but you can't prevent objection by allowing objection. 'Cooperation' and 'compliance' are positive outcomes, not problems to prevent.

Electronics Engineering QUESTION #11720

Question 7986

The purpose of a pre-charge circuit in a battery management system (BMS) for a Li-ion pack is to:

Equalise cell voltages before main charging begins
Limit inrush current to capacitive loads at initial power-up
Trickle charge deeply discharged cells below 2.5 V before full CC charge✔️
Balance cells using a passive resistor network

Correct Answer Logic:

Pre-charge in Li-ion BMS applies a low current (typically C/10 or less) to deeply discharged cells with voltage below ~2.5–3.0 V per cell. Charging a deeply discharged Li-ion cell at full CC current can cause lithium plating, internal short circuits, and thermal runaway. Pre-charge safely recovers the cell to a safe voltage before commencing full CC charging.

Chemistry QUESTION #1019

Question 7987

Match the compounds (List-I) with appropriate catalysts/reagents (List-II) for reduction to amines. (A) $R\text{-CO-NH}_2$ (amide) (B) Nitrobenzene (C) $R\text{-C}{\equiv}\text{N}$ (nitrile) (D) Imide ($N$-substituted cyclic imide). Reagents: (I) NaOH(aq) (II) $\text{H}_2$/Ni (III) $\text{LiAlH}_4, \text{H}_2\text{O}$ (IV) Sn, HCl

(A)-(II), (B)-(I), (C)-(III), (D)-(IV)

(A)-(II), (B)-(IV), (C)-(III), (D)-(I)
(A)-(III), (B)-(IV), (C)-(II), (D)-(I)✔️

Correct Answer Logic:

Amide (A) reduced by $\text{LiAlH}_4$ (III). Nitrobenzene (B) reduced by Sn/HCl (IV) — classic reduction. Nitrile (C) reduced by $\text{H}_2/\text{Ni}$ (II). Cyclic imide (D) — Hofmann-like with NaOH(aq) (I). Matching: A-III, B-IV, C-II, D-I.

Molecular Biology / Bioinformatics / Biochemistry QUESTION #11130

Question 7989

Which reaction is the first step in photorespiration?

Decarboxylation
Oxygenation✔️
Carboxylation
Phosphorylation

Correct Answer Logic:

The first reaction of photorespiration is oxygenation — RuBisCO catalyses the addition of $\text{O}_2$ (instead of $\text{CO}_2$) to ribulose-1,5-bisphosphate (RuBP), producing one molecule of 3-phosphoglycerate and one molecule of 2-phosphoglycolate. This competitive oxygenase activity of RuBisCO initiates the photorespiratory carbon oxidation cycle. The phosphoglycolate is then dephosphorylated to glycolate, which enters the peroxisome. Photorespiration reduces photosynthetic efficiency in $\text{C}_3$ plants by up to 25–30%.

Question 7990

Under the budgetary procedure a Ministry proposes a lump-sum provision in its Current Expenditure budget for an item not yet fully specified. What principle does this violate and what is the correct course?

It violates the Prudence principle; the item should be deferred to the next year
Lump-sum provisions in Current Expenditure are prohibited except in exceptional circumstances and must require the concurrence of the Financial Adviser when made✔️
It violates the Purpose principle; the item should be separately itemized without Financial Adviser involvement
It is acceptable practice as long as PAO certifies the amount

Correct Answer Logic:

Lump-sum provision in the budget shall not be proposed or made except in exceptional circumstances (such as lump provision for late NIS late receipt of directives). Where such provision is made expenditure sanction shall be given with the concurrence of the Financial Adviser.

Nursing QUESTION #9136

Question 7994

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%.

Chemistry QUESTION #5523

Question 7996

Identify the reaction that is NOT part of the ozone layer depletion mechanism in the stratosphere.

$CF_2Cl_2(g) \xrightarrow{hv} \cdot Cl(g) + \cdot CF_2Cl(g)$
$Cl\dot{O}(g) + O(g) \rightarrow \cdot Cl(g) + O_2(g)$
$CH_4 + 2O_3 \rightarrow 3\,CH_2{=}O + 3H_2O$✔️
$HOCl(g) \xrightarrow{hv} \cdot OH(g) + \cdot Cl(g)$

Correct Answer Logic:

The ozone depletion cycle involves: (A) CFCs releasing Cl radicals under UV, (B) ClO reacting with O atom to regenerate Cl radical (chain propagation), (D) HOCl photolysis to give OH and Cl radicals — all are real steps. Option (C), the reaction of $CH_4$ with $O_3$ to give formaldehyde and water, is NOT a recognized step in stratospheric ozone depletion chemistry.

Boilers Mechanical Engineering QUESTION #2451

Question 7999

The static deflection $x_{st} = F_0/k$ is used to express the natural frequency as:

$\omega_n = \sqrt{g/x_{st}}$ (using gravity $g$ and static deflection under weight)✔️
$\omega_n = x_{st}/g$
$\omega_n = k\cdot x_{st}$
$\omega_n = g\cdot x_{st}$

Correct Answer Logic:

Since $x_{st}=mg/k$, we have $k/m=g/x_{st}$, hence $\omega_n=\sqrt{k/m}=\sqrt{g/x_{st}}$.
