What are the most common types of side effects from SSRIs?
Diarrhea and weight gain
Dizziness, drowsiness, and dry mouth
Convulsions and respiratory difficulties
Jaundice and agranulocytosis
The Correct Answer is B
Choice A reason: Diarrhea and weight gain are less common with SSRIs. While some SSRIs may cause gastrointestinal upset via serotonin receptor stimulation in the gut, weight gain is more associated with atypical antipsychotics. SSRIs primarily affect serotonin reuptake, leading to central and anticholinergic-like effects, not these symptoms predominantly.
Choice B reason: SSRIs, by inhibiting serotonin reuptake, cause dizziness, drowsiness, and dry mouth due to central nervous system effects and mild anticholinergic activity. Dizziness and drowsiness result from serotonin modulation in the brainstem, while dry mouth reflects peripheral serotonin effects on salivary glands, making these the most common side effects.
Choice C reason: Convulsions and respiratory difficulties are rare with SSRIs. Seizures may occur in overdose due to excessive serotonin, but not typically at therapeutic doses. Respiratory issues are not associated, as SSRIs primarily affect serotonin pathways, not respiratory centers, making this choice inaccurate for common side effects.
Choice D reason: Jaundice and agranulocytosis are not common SSRI side effects. These are associated with drugs like chlorpromazine, affecting liver or bone marrow. SSRIs primarily cause serotonin-related central and peripheral effects, not hepatotoxicity or bone marrow suppression, making this choice irrelevant to their pharmacological profile.

Correct Answer is B
Explanation
Choice A reason: Understanding the medication regimen is important for long-term bipolar management, stabilizing mood via dopamine and serotonin modulation. In acute mania, however, hyperactivity and reduced intake increase dehydration risk, which exacerbates cerebral dysfunction. Hydration is a more immediate physiological need than cognitive understanding during an acute episode.
Choice B reason: Acute mania in bipolar disorder involves hyperactivity and reduced self-care, driven by dopamine dysregulation, leading to dehydration. This impairs cerebral perfusion and electrolyte balance, risking seizures or organ damage. Maintaining hydration is the priority, as it stabilizes physiological function, supporting neural recovery during the acute manic phase.
Choice C reason: Practicing problem-solving skills aids long-term bipolar management by enhancing prefrontal cortex function. In acute mania, however, impaired insight and hyperactivity from dopamine excess limit cognitive engagement. Dehydration poses a greater immediate risk to cerebral and systemic stability, making this goal secondary during an acute episode.
Choice D reason: Identifying relapse indications supports long-term bipolar management by recognizing dopamine-driven mood shifts. In acute mania, immediate physiological risks like dehydration from hyperactivity take precedence, as they threaten cerebral and systemic stability. This goal is less urgent, as it addresses future prevention rather than current physiological needs.
Correct Answer is D
Explanation
Choice A reason: Tylenol with Codeine (acetaminophen and codeine) in tablet form (1T) typically refers to a standard dose, but in liquid form, the concentration varies. Assuming a common elixir (120 mg acetaminophen/12 mg codeine per 5 mL), 15 mL delivers the standard dose. 15.5 mL slightly exceeds this, risking overdose and potential hepatotoxicity from acetaminophen, making it incorrect.
Choice B reason: Tylenol with Codeine elixir is commonly 120 mg acetaminophen and 12 mg codeine per 5 mL. One tablet equivalent (1T) typically corresponds to 15 mL, delivering 360 mg acetaminophen and 36 mg codeine, aligning with standard dosing for pain relief. This volume ensures therapeutic efficacy without exceeding safe limits, matching pharmacological guidelines.
Choice C reason: A 40 mL dose of Tylenol with Codeine elixir (120 mg acetaminophen/12 mg codeine per 5 mL) would deliver 960 mg acetaminophen and 96 mg codeine, far exceeding safe single-dose limits. This risks acetaminophen-induced liver toxicity and opioid-related respiratory depression, as it disrupts the therapeutic window, making this choice scientifically inappropriate.
Choice D reason: A 30 mL dose of Tylenol with Codeine elixir (120 mg acetaminophen/12 mg codeine per 5 mL) provides 720 mg acetaminophen and 72 mg codeine, doubling a typical single dose. This excessive amount increases the risk of hepatotoxicity and opioid side effects like sedation or respiratory depression, rendering it unsuitable for standard administration.
