Toxicology & Poisoning
1. Management for an ingested poison focuses mainly on:
A) the prompt induction of vomiting.
B) administering a counteracting agent.
C) neutralizing the poison in the stomach.
D) treating the systemic effects that result.
Answer-: C) neutralizing the poison in the stomach.
Rationale: For ingested poisons, the primary focus is on neutralizing or removing
the poison from the stomach to prevent systemic absorption and reduce toxicity .
2. From an anatomic and physiologic perspective, inhaled toxins:
A) generally provide a large window of opportunity for treatment.
B) quickly reach the alveoli and rapidly gain access to the circulatory system.
C) typically take between 15 and 20 minutes to exert a systemic effect.
D) often take several hours before clinical signs and symptoms manifest.
Answer-: B) quickly reach the alveoli and rapidly gain access to the circulatory
system.
Rationale: Inhaled toxins have direct access to the alveoli, where gas exchange
,occurs, allowing rapid absorption into the bloodstream and quick onset of
systemic effects .
3. Exposure to sarin or tabun would result in:
A) hyperthermia.
B) pupillary dilation.
C) severe tachycardia.
D) excessive lacrimation.
Answer-: D) excessive lacrimation.
Rationale: Sarin and tabun are nerve agents that inhibit acetylcholinesterase,
leading to cholinergic crisis characterized by excessive salivation, lacrimation,
urination, defecation, gastrointestinal distress, and emesis (SLUDGE syndrome) .
4. Patients with alcoholism are prone to subdural hematomas and
gastrointestinal bleeding because:
A) they fall more frequently than sober people.
B) their blood-clotting mechanisms are impaired.
C) they are at higher risk for violent assault.
D) alcohol causes significant immunocompromise.
Answer-: B) their blood-clotting mechanisms are impaired.
Rationale: Chronic alcoholism leads to liver dysfunction and impaired synthesis of
clotting factors, increasing the risk of bleeding complications such as subdural
hematomas and gastrointestinal hemorrhage .
5. Symptoms of delirium tremens usually begin within ______ hours after the
last alcohol intake.
A) 12 to 24
B) 24 to 48
C) 48 to 72
D) 72 to 96
,Answer-: C) 48 to 72 hours.
Rationale: Delirium tremens typically begins 48 to 72 hours after the last alcohol
intake in patients with alcohol dependence, presenting with severe agitation,
hallucinations, and autonomic instability .
6. The clinical presentation of a stimulant abuser includes:
A) excitement, hypertension, tachycardia, and dilated pupils.
B) anxiety, hypotension, hypothermia, and depressed reflexes.
C) confusion, seizures, bradycardia, and constricted pupils.
D) paranoia, hypothermia, hyperreflexia, and constricted pupils.
Answer-: A) excitement, hypertension, tachycardia, and dilated pupils.
Rationale: Stimulants such as cocaine and amphetamines cause sympathetic
nervous system activation, resulting in CNS excitation, increased heart rate and
blood pressure, and mydriasis (dilated pupils) .
7. Which of the following interventions is influenced strongly by the amount of
time that has elapsed since a patient ingested a toxic substance?
A) Transport
B) IV therapy
C) Intubation
D) Gastric lavage
Answer-: D) Gastric lavage.
Rationale: Gastric lavage is most effective when performed within one hour of
ingestion. Beyond that window, the toxin has likely passed beyond the stomach,
making lavage less beneficial .
8. The bioavailability and excretion rate of a toxin are influenced by the:
A) amount of toxin and the relative speed at which it is metabolized.
B) type of toxin and the condition of the patient's underlying health.
C) route by which the toxin entered the body and the age of the patient.
D) the presence of other substances in the body at the time of exposure.
, Answer-: A) amount of toxin and the relative speed at which it is metabolized.
Rationale: The dose of toxin and the rate of metabolism directly impact how
much of the substance reaches systemic circulation (bioavailability) and how
quickly it is eliminated (excretion rate) .
9. Which of the following toxins causes the MOST serious consequences when
absorbed through the skin?
A) Dry lime
B) Poison oak
C) Organophosphates
D) Hydrocarbons
Answer-: C) Organophosphates.
Rationale: Organophosphates (insecticides, nerve agents) are rapidly absorbed
through intact skin and cause severe cholinergic toxicity that can be life-
threatening. Prompt decontamination is critical .
10. A person who consumes alcohol is considered to be physically dependent if:
A) abrupt cessation of drinking causes withdrawal symptoms.
B) they have been drinking excessively for more than one year.
C) they consume alcohol daily regardless of the amount.
D) they require increasing amounts to achieve the same effect.
Answer-: A) abrupt cessation of drinking causes withdrawal symptoms.
Rationale: Physical dependence is defined by the development of withdrawal
symptoms when the substance is discontinued. Tolerance (needing more to
achieve the same effect) is related but distinct .
Pediatric Emergencies
11. Unlike sinus tachycardia, supraventricular tachycardia in infants is
characterized by:
A) a variable pulse rate.
B) an unvarying pulse rate.
