A 17 year old asthmatic patient has been told that marijuana may help with his anxiety. Which adverse effect has been associated with marijuana and may be a reason for this patient to avoid use of marijuana?

Correct Answer: A

Rationale: The correct answer is A: Short term memory loss. Marijuana has been associated with impairing short-term memory due to its effects on the brain's hippocampus. This may be concerning for the 17-year-old asthmatic patient as it can affect cognitive function, learning, and overall daily functioning. Other choices are incorrect: B: Hepatitis is not directly associated with marijuana use. C: Hyperthermia is more commonly linked to stimulant drug use rather than marijuana. D: Hyponatremia is not a well-known adverse effect of marijuana.

Correct Answer: B

Rationale: Rationale: Choice B is correct because tremors are a known common side effect of albuterol inhalant, usually temporary. This response reassures the patient and provides accurate information. Choice A is unnecessary as tremors are a common side effect, not requiring immediate intervention. Choice C is incorrect as the tremors are likely related to the medication. Choice D is not the best response as the patient's concern can be addressed by explaining the common side effect and its temporary nature.

Correct Answer: D

Rationale: Step 1: Orlistat is a medication that works by blocking the absorption of fats in the intestine. Step 2: This leads to increased fat content in the stool, causing oily spotting as a common adverse effect. Step 3: Fecal urgency, bloody stool, and fatty stool are not typical adverse effects of Orlistat. Step 4: Fecal urgency is more common with stimulant laxatives, bloody stool may indicate gastrointestinal bleeding, and fatty stool is not a recognized side effect of Orlistat. Step 5: Therefore, the correct answer is D (Oily spotting) as it aligns with the mechanism of action of Orlistat, while the other options are not associated with this medication.

Correct Answer: D

Rationale: The correct answer is D: Cell-mediated immunity. This type of immunity involves the activation of T cells, which directly attack and destroy infected cells to stop the virus from reproducing. T cells play a crucial role in controlling intracellular pathogens like viruses. A and B are incorrect because they refer to aspects of humoral immunity, which involve B cells producing antibodies to target pathogens in the bloodstream, not infected cells. C, hapten immunity, is not a valid term in immunology and does not relate to the immune response against viruses.

Correct Answer: C

Rationale: The correct answer is C: Free T4 (FT4). The thyroid gland primarily releases thyroid hormones T4 and T3, with FT4 being the active form. Calcitonin is released by the thyroid but is not a primary hormone. TRH is released by the hypothalamus to stimulate TSH release from the pituitary gland. TSH is released by the pituitary gland to stimulate the thyroid to produce and release T4 and T3. Therefore, C is the correct answer as FT4 is one of the primary hormones directly released by the thyroid gland.
