A dentist refers a 21-year-old woman with a BMI of 26 to the PMHNP after he discovers significant enamel erosion and decay of her front teeth. What diagnosis does the dentist suspect?
Anorexia nervosa
Binge eating disorder
Atypical eating disorder
Bulimia nervosa
The Correct Answer is D
Choice A reason: Anorexia nervosa involves restriction of caloric intake and often leads to significantly low body weight. This patient’s BMI is in the overweight range, making anorexia less likely.
Choice B reason: Binge eating disorder involves recurrent episodes of excessive food consumption without compensatory behaviors. While it may affect BMI, it typically does not cause enamel erosion.
Choice C reason: Atypical eating disorder is a broad category used when individuals exhibit some symptoms of eating disorders but do not meet full criteria. The pattern of enamel erosion strongly suggests purging behavior, indicating a more specific diagnosis.
Choice D reason: This is correct. Bulimia nervosa involves recurrent binge eating episodes followed by compensatory behaviors such as self-induced vomiting. Repeated vomiting exposes teeth to gastric acid, causing enamel erosion and dental decay, which aligns with the dentist’s findings.

Correct Answer is B
Explanation
Choice A reason: This response is overly simplistic and uses the word "cheating," which may sound accusatory and does not accurately explain the clinical rationale. The ADOS aims to assess a child's independent social, communicative, and behavioral functioning, not to catch parents assisting. Using such terminology may increase parental anxiety and reduce cooperation.
Choice B reason: This is the correct response because it clearly explains that the assessment's purpose is to observe the child’s behavior without parental influence. Parental presence can inadvertently alter a child's responses or behavior, potentially masking deficits in social communication or repetitive behaviors that are critical for the diagnosis of autism spectrum disorder. The phrasing reassures parents while providing a clear professional rationale.
Choice C reason: While the test may indeed be challenging, emphasizing the child’s potential inability to complete tasks is not the appropriate rationale for asking parents to leave. This approach may unnecessarily alarm parents and distract from the primary reason for their absence, which is to ensure accurate and unbiased assessment of the child.
Choice D reason: This answer incorrectly assumes that children’s distress is solely due to parental presence. While some children may behave differently with parents around, the main rationale for asking parents to leave is to obtain an independent assessment of the child's skills and behaviors, not simply to prevent emotional upset.
Correct Answer is B
Explanation
Choice A reason: White blood cell measurement is not a specific or sensitive indicator for rheumatoid arthritis activity or response to treatment. White blood cells can be elevated in any infection, inflammatory state, or due to certain medications, but they do not directly reflect joint inflammation or autoimmune activity in rheumatoid arthritis. WBC levels are useful primarily for detecting infection or bone marrow suppression due to drug therapy rather than monitoring disease progression.
Choice B reason: The erythrocyte sedimentation rate (ESR) is a reliable and widely used indicator of inflammation and is commonly utilized to assess response to treatment in rheumatoid arthritis. ESR measures the rate at which red blood cells settle at the bottom of a test tube over one hour. An increased rate reflects elevated levels of acute-phase proteins such as fibrinogen, which correlate with systemic inflammation. When treatment is effective and inflammation subsides, the ESR value decreases, making it a sensitive marker for monitoring disease activity over time.
Choice C reason: Hemoglobin measurement primarily assesses for anemia, which may be secondary to chronic inflammation or bone marrow suppression from medications. Although anemia can occur in rheumatoid arthritis (known as anemia of chronic disease), hemoglobin levels are not used to gauge response to therapy or inflammation levels.
Choice D reason: Measurement of absolute neutrophils helps detect neutropenia or infection, particularly in patients on immunosuppressive therapy, but it does not measure inflammatory activity or disease response. It is mainly a safety monitoring parameter, not a treatment response marker.
