Therapeutics and Patient Care QUESTION #3901

Question 7

Among the following options, which drug is the LEAST suitable for the acute abortive treatment of migraine headache?

Oxycodone✔️
Ibuprofen
Sumatriptan

Question 8

The complementary base pairing in DNA is important because it:

Maintains the tertiary structure of enzymes
Provides energy for all cell metabolism
Enables protein to fold properly
Allows DNA to act as a genetic blueprint during replication✔️

Correct Answer Logic:

Complementary base pairing (A–T, G–C) ensures accurate replication — each strand acts as a template, making DNA the reliable genetic blueprint.

Question 10

In verbal subject approaches, a pre-coordinated subject heading system combines multiple subject concepts at which stage?

At the time of searching
At the time of indexing✔️
At the time of acquisition
At the time of shelving

Correct Answer Logic:

Pre-coordination occurs at the time of indexing — the cataloguer combines multiple concepts into a single complex heading before the record is stored. Post-coordination allows users to combine terms at the time of searching.

Mathematics QUESTION #4158

Question 13

For the Laplace equation $u_{xx} + u_{yy} = 0$ on $0 < x < a$, $0 < y < b$ with $u(0,y) = u(a,y) = u(x,0) = 0$ and $u(x,b) = f(x)$, what is the general form of solution using separation of variables?

$u(x,y) = \sum_{n=1}^{\infty} B_n \sin(\frac{n\pi x}{a})\sinh(\frac{n\pi y}{a})$✔️
$u(x,y) = \sum_{n=1}^{\infty} B_n \cos(\frac{n\pi x}{a})\cosh(\frac{n\pi y}{a})$
$u(x,y) = \sum_{n=1}^{\infty} B_n \sin(\frac{n\pi x}{a})\cos(\frac{n\pi y}{b})$
$u(x,y) = \sum_{n=1}^{\infty} B_n e^{\frac{n\pi x}{a}}\sin(\frac{n\pi y}{b})$

Correct Answer Logic:

Boundary conditions $u(0,y) = u(a,y) = 0$ suggest $X(x) = \sin(\frac{n\pi x}{a})$. Condition $u(x,0) = 0$ gives $Y(0) = 0$, so $Y(y) = \sinh(\frac{n\pi y}{a})$.

Physics QUESTION #1164

Question 15

In which process is all the heat supplied converted into work done?

Isothermal✔️
Isochoric
Isobaric
Isentropic

Correct Answer Logic:

In a reversible isothermal process (constant temperature) for an ideal gas, the internal energy change $\Delta U = 0$ (since $U$ depends only on temperature). By the first law: $Q = \Delta U + W = W$. So all heat supplied is entirely converted to work done.

Question 16

Which of the following is a PRIME number?

91
87
97✔️
111

Correct Answer Logic:

A prime number has exactly two factors: 1 and itself. 97 is only divisible by 1 and 97, making it prime. 91 = 7 × 13, 87 = 3 × 29, and 111 = 3 × 37, so they are composite.

Question 17

Which isotope of hydrogen emits low-energy $\beta^-$ particles?

Proton $H^+$
Tritium $^3_1H$✔️
Protium $^1_1H$
Deuterium $^2_1H$

Correct Answer Logic:

Tritium ($^3_1H$) is a radioactive isotope of hydrogen containing 1 proton and 2 neutrons. It undergoes beta decay: $^3_1H \to ^3_2He + \beta^- + \bar{\nu}_e$. The emitted $\beta^-$ particles have very low energy (~18 keV max). Protium and deuterium are stable; $H^+$ is simply a proton with no radioactivity.

Question 18

For $y'' + y = \sec(x)$, using variation of parameters, what is $u_1'$ where $y_p = u_1\cos(x) + u_2\sin(x)$?

$-\sin(x)\sec(x)$
$-\sin(x)\sec(x) = -\tan(x)$✔️
$\cos(x)\sec(x) = 1$
$\tan(x)$

Correct Answer Logic:

$u_1' = -\frac{y_2 f(x)}{W} = -\frac{\sin(x) \sec(x)}{1} = -\tan(x)$.

Physics QUESTION #7002

Question 19

The energy to take a satellite to height $h$ above Earth (radius $R_E = 6.4 \times 10^3\ \text{km}$) is $E_1$, and the kinetic energy to maintain circular orbit at that height is $E_2$. For what value of $h$ is $E_1 = E_2$?

$1.6 \times 10^3\ \text{km}$
$3.2 \times 10^3\ \text{km}$✔️
$6.4 \times 10^3\ \text{km}$
$1.28 \times 10^4\ \text{km}$

Correct Answer Logic:

$E_1 = \frac{GMm}{R_E} - \frac{GMm}{R_E+h} = GMm\frac{h}{R_E(R_E+h)}$

$E_2 = \frac{GMm}{2(R_E+h)}$ (orbital KE)

Setting $E_1 = E_2$:

$\frac{h}{R_E(R_E+h)} = \frac{1}{2(R_E+h)}$

$\frac{h}{R_E} = \frac{1}{2}$

$h = \frac{R_E}{2} = \frac{6.4 \times 10^3}{2} = 3.2 \times 10^3\ \text{km}$

Verbal Reasoning QUESTION #8096

Question 20

Compare the two quantities below.

Column A: The number of months in 7 years

Column B: The number of days in 12 weeks

Column A is greater
Column B is greater
The two quantities are equal✔️
The relationship cannot be determined from the information given

Correct Answer Logic:

Column A: $7 \text{ years} \times 12 \text{ months/year} = 84$ months.

Column B: $12 \text{ weeks} \times 7 \text{ days/week} = 84$ days.

Both quantities equal 84, so the two quantities are equal.
