Question 1 of 5
A 39-year-old man with long-standing allergies has no health insurance and simply takes over-the-counter diphenhydramine for symptom relief. He has no other medical problems but uses this medication up to four times per day. Which of the following effects of this medication is possible to be experienced by this patient?

Question 3 of 5
What is pharmacodynamics?
Correct Answer: B
Rationale: Pharmacodynamics refers to the study of the biochemical, physiological, and behavioral effects of drugs on the body and their mechanisms of action. It specifically focuses on the drugs' actions at the receptor site and how these actions lead to specific responses in the body. This includes understanding how drugs interact with target receptors, enzymes, and other molecular targets within the body to produce their effects. Pharmacodynamics also involves studying the relationship between the drug concentration and the magnitude of the response it elicits, as well as factors influencing the variability in individual responses to a drug. In summary, pharmacodynamics is crucial for understanding how drugs work in the body and how they produce their therapeutic or adverse effects.

Question 5 of 5
An 18-year-old man is brought to the emergency department by a friend after smoking crack cocaine because he was 'acting funny.' His temperature is 38°C (100.4°F), pulse is 110 beats/minute, and he appears agitated. Which of the following is an effect of cocaine intoxication?
Correct Answer: D
Rationale: Cocaine intoxication (agitation, tachycardia, fever) causes vasoconstriction , via sympathetic stimulation, raising BP and temperature. Hypercoagulability occurs but isn't primary. Hypocoagulability and hypothermia oppose effects. Vasodilation (E) is wrong. This drives his symptoms.
