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):

The diagonal of the rectangle is 10 and one side is 6.

Using the Pythagorean theorem: $\text{diagonal}^2 = \text{length}^2 + \text{width}^2$

$10^2 = 6^2 + w^2 \Rightarrow 100 = 36 + w^2 \Rightarrow w^2 = 64 \Rightarrow w = 8$

Perimeter $= 2(6 + 8) = 2 \times 14 = 28$.

The passage emphasizes that higher productivity no longer ensures wage increases because of other structural factors — exactly what option C states.

The apparent dip $\delta'$ is the angle of dip observed when the dip circle is not oriented in the magnetic meridian (tilted at angle $\phi$ from the meridian).

The relationship is: $\tan\delta' = \frac{\tan\delta}{\cos\phi}$, where $\delta$ is the true dip.

Since $\cos\phi \leq 1$: $\tan\delta' \geq \tan\delta$, so $\delta' \geq \delta$.

Therefore true dip is always less than or equal to apparent dip. They are equal only when $\phi = 0°$ (dip circle in the meridian).
