Nursing QUESTION #9210

A Head Nurse reads a study where the researchers interviewed 12 nurses until no new themes emerged. What sampling method was used?

Quota sampling
Purposive sampling until theoretical saturation✔️
Snowball sampling
Stratified random sampling

Correct Answer Logic:

Correct Answer: B — Purposive sampling until theoretical saturation

In qualitative research, the concept of theoretical (or data) saturation refers to the point at which no new information or themes are emerging from additional data collection.

Why 'purposive sampling'? Qualitative researchers deliberately select participants based on specific characteristics relevant to the research question — this is purposive (or purposeful) sampling.

Comparison of qualitative sampling methods:

Method	Description
Purposive	Deliberate selection based on specific criteria
Snowball	Participants recruit other participants (used for hard-to-reach populations)
Theoretical	Sampling continues until saturation — guided by emerging theory (Grounded Theory)

Sample size in qualitative research is determined by saturation, not pre-calculated formulas.

Physics QUESTION #7072

Question 3

Two radioactive isotopes, $A$ and $B$, have half-lives of $20$ minutes and $40$ minutes, respectively. If both samples start with an identical number of nuclei, determine the ratio of the number of decayed nuclei of $A$ to those of $B$ after a period of $80$ minutes.

$4:1$
$1:4$
$5:4$✔️
$1:16$

Correct Answer Logic:

After $80$ minutes, $A$ undergoes $4$ half-lives ($80/20$), leaving $N_A = N_0/2^4 = N_0/16$. The number of decayed nuclei for $A$ is $N_0 - N_0/16 = 15N_0/16$. $B$ undergoes $2$ half-lives ($80/40$), leaving $N_B = N_0/2^2 = N_0/4$. The number of decayed nuclei for $B$ is $N_0 - N_0/4 = 3N_0/4 = 12N_0/16$. The ratio of decayed nuclei is $15:12$, which simplifies to $5:4$.

Question 4

Antonyms and Synonyms:
Which word is the antonym of "Splenetic"?

Calm
Casual
Genial✔️
None of these

Correct Answer Logic:

'Splenetic' means bad-tempered, irritable, or spiteful. The antonym would be 'Genial', which means friendly, cheerful, and pleasant. While 'calm' is also opposite in nature, 'genial' is the better antonym as it represents the positive temperament opposite to the negative irritability of 'splenetic'.

Chemistry QUESTION #1070

Question 5

If the rate constant of a reaction is $0.03\ \text{s}^{-1}$, how much time does it take for $7.2\ \text{mol L}^{-1}$ concentration to get reduced to $0.9\ \text{mol L}^{-1}$? (Given: $\log 2 = 0.301$)

210 s✔️
21.0 s
69.3 s
23.1 s

Correct Answer Logic:

This is a first-order reaction ($k = 0.03\ \text{s}^{-1}$). $t = \frac{2.303}{k}\log\frac{[A]_0}{[A]} = \frac{2.303}{0.03}\log\frac{7.2}{0.9} = \frac{2.303}{0.03}\log 8 = \frac{2.303\times3\times0.301}{0.03} = \frac{2.079}{0.03} \approx 69.3\ \text{s}$. Wait — $\frac{2.303\times0.903}{0.03}=\frac{2.079}{0.03}=69.3\text{ s}$. But answer key says 210s: $\log 8 = 3\times0.301=0.903$, $t=\frac{2.303\times0.903}{0.03}=69.3\text{ s}$. So answer is option (3) = 69.3 s.

Civil / Architecture QUESTION #2370

Question 9

In the context of Occupational Health and Safety (OHS), the Hierarchy of Controls for managing workplace hazards lists five levels in order of effectiveness. Which sequence is correct from MOST to LEAST effective?

Administrative controls → PPE → Substitution → Engineering controls → Elimination
Elimination → Substitution → Engineering controls → Administrative controls → PPE✔️
PPE → Administrative controls → Engineering controls → Substitution → Elimination
Engineering controls → Elimination → PPE → Substitution → Administrative controls

Correct Answer Logic:

The Hierarchy of Controls from most to least effective is: (1) Elimination — physically remove the hazard; (2) Substitution — replace the hazard with something safer; (3) Engineering controls — isolate people from the hazard (guards, ventilation); (4) Administrative controls — change the way people work (procedures, training, schedules); (5) PPE — protect the worker with personal protective equipment. PPE is the last resort as it does not remove the hazard.

Verbal Reasoning QUESTION #8104

Question 13

For all real numbers $a$, let $a^* = 1 - a$.

Compare:

Column A: $((-1)^*)^*$

Column B: $2^*$

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:

Using the definition $a^* = 1 - a$:

Step 1: $(-1)^* = 1 - (-1) = 2$

Step 2: $((-1)^*)^* = (2)^* = 1 - 2 = -1$

Column A $= -1$

Column B: $2^* = 1 - 2 = -1$

Both quantities equal $-1$, so the two quantities are equal.

Mathematics QUESTION #1288

Question 19

A linear transformation $T:\mathbb{R}^3\to\mathbb{R}^2$ must satisfy, for all $\mathbf{u},\mathbf{v}\in\mathbb{R}^3$ and scalar $c$:

T($\mathbf{u}+\mathbf{v}) = T(\mathbf{u})\cdot T(\mathbf{v})$
T(c$\mathbf{u}) = c^2T(\mathbf{u})$
T($\mathbf{u}+\mathbf{v}) = T(\mathbf{u})+T(\mathbf{v})$ and $T(c\mathbf{u})=cT(\mathbf{u})$✔️
T must be onto

Correct Answer Logic:

A linear transformation satisfies two properties: (1) Additivity: $T(\mathbf{u}+\mathbf{v})=T(\mathbf{u})+T(\mathbf{v})$, and (2) Homogeneity: $T(c\mathbf{u})=cT(\mathbf{u})$. Both must hold simultaneously. Together they imply $T(c\mathbf{u}+d\mathbf{v})=cT(\mathbf{u})+dT(\mathbf{v})$.

Verbal Reasoning QUESTION #8186

Question 20

If $0 < a < 1 < b$, which inequality correctly describes the reciprocals of $a$ and $b$?

$1 < \dfrac{1}{a} < \dfrac{1}{b}$
$\dfrac{1}{a} < 1 < \dfrac{1}{b}$
$\dfrac{1}{b} < \dfrac{1}{a} < 1$
$\dfrac{1}{b} < 1 < \dfrac{1}{a}$✔️

Correct Answer Logic:

Since $0 < a < 1$: taking the reciprocal reverses the inequality, so $\dfrac{1}{a} > 1$.

Since $b > 1$: taking the reciprocal reverses the inequality, so $\dfrac{1}{b} < 1$.

Therefore: $\dfrac{1}{b} < 1 < \dfrac{1}{a}$.

For example, $a = 0.5,\ b = 2$: $\dfrac{1}{a} = 2,\ \dfrac{1}{b} = 0.5$. Indeed $0.5 < 1 < 2$. ✓
