Your patient presents with wheezing, coughing and increased respiratory effort. This occurred following inhalation of chlorine gas. What pathophysiological process is involved?

➤ Why does low serotonin contribute to anxiety symptoms?
Serotonin regulates mood, anxiety, and threat processing in the amygdala and prefrontal cortex. Low serotonin reduces inhibitory control over fear circuits, which increases worry, rumination, and physiological arousal. This imbalance makes it harder to extinguish conditioned fear and maintain calm, worsening persistent anxious feelings.

➤ Why is converting to units/hr important for patient safety?
Converting to units/hr ensures accurate pump settings and prevents dosing errors. Heparin has a narrow therapeutic range and requires lab monitoring (aPTT or anti‑Xa). Miscalculations can cause bleeding or thrombosis. Verify vial strength, total volume, and have a second clinician confirm high‑risk infusion calculations.

➤ How do dopamine and norepinephrine differ in their roles for ADHD symptoms?
Dopamine mainly affects reward processing, motivation, motor activity, and cognitive flexibility via striatal and prefrontal circuits. Norepinephrine, from the locus coeruleus, supports sustained attention, vigilance, and response inhibition in the prefrontal cortex. Dysfunction in both systems produces the combined attention and behavioral control problems seen in ADHD.

Why and why not should healthcare organizations adhere to patient access to their medical record, protection of patient information and informed consent regulations and laws? ​

➤ When is it most important to access another organization’s patient history?
When treating emergencies, transitions of care, referrals, or preoperative assessments, accessing another organization’s records is most valuable. It supports rapid decision-making by revealing allergies, recent imaging, laboratory trends, and advance directives. Timely access during admissions, discharge planning, or chronic disease management reduces risks and helps personalize urgent or longitudinal care.

Which of the following is an example of primary prevention?

Scoliosis screening for children
HIV testing for high risk patients
