Answer to Question 1

ANS: C
Marijuana causes pronounced reddening of the conjunctiva.
Marijuana use typically increases the heart rate 20 to 50 beats per minute, therefore tachycardia, not bradycardia, would be present.
The conjunctiva becomes reddened, not pale, with marijuana use.
Marijuana use, even in high doses, does not cause edema.

Answer to Question 2

ANS: A
Severe overdose can produce hyperpyrexia, convulsions, ventricular dysrhythmias, and hemorrhagic stroke.
Death is not imminent based on the patient's clinical presentation.
Hallucinations and tremors are typically seen with mild overdose.
Angina and myocardial infarction may occur. Myocardial infarction typically precedes death. The patient's clinical presentation would make convulsions most likely at this time.
