This clinical picture suggests giant cell arteritis (GCA) associated with polymyalgia rheumatica: new-onset headache in an older patient, proximal muscle pain and stiffness (shoulders and hips), systemic symptoms (weight loss), and mood changes. MCCQE objectives emphasize that GCA is a medical emergency because inflammation of the temporal and other cranial arteries can lead to irreversible vision loss due to ischemic optic neuropathy.

The most important objective of treatment is prevention of blindness , which requires prompt initiation of high-dose corticosteroids—often before confirmatory temporal artery biopsy—to reduce arterial inflammation and prevent vascular occlusion. While improving musculoskeletal pain and headache are important symptomatic goals, they are secondary to preventing permanent complications. Jaw claudication is a symptom of arterial insufficiency but not itself the primary outcome to prevent.

Early recognition and immediate corticosteroid therapy significantly reduce the risk of bilateral, permanent visual loss. Therefore, prevention of blindness is the most critical treatment objective.

This presentation describes normal developmental dysfluency, which typically occurs between ages 2–5 and often worsens during times of stress or change, such as a new sibling. It is characterized by word repetition and does not require intervention unless it persists > 6 months, worsens, or causes distress.

Toronto Notes 2023 – Pediatrics, " Developmental and Behavioral Pediatrics " Section:

“Developmental stuttering is common between 2–5 years and often resolves without intervention. Reassurance is appropriate unless there are signs of persistent or severe stuttering, secondary behaviors, or parental concern.”

MCCQE1 Objectives (Pediatrics > 78-1: Development and Behavior):

“Candidates must recognize typical patterns of developmental speech dysfluency and differentiate them from pathological speech disorders. Observation and reassurance are often the appropriate initial step.”

Because the child is otherwise developing normally and the onset coincides with a known psychosocial stressor, reassurance is the most appropriate step. Formal speech or behavioral therapy is not indicated at this time.

A slowly enlarging, hard inguinal “lump” in an older adult is concerning for inguinal lymphadenopathy or an inguinal hernia , and MCCQE objectives emphasize targeted examination of the regional drainage areas to identify a primary source. Inguinal lymph nodes receive lymphatic drainage from the external genitalia and scrotal skin , perineum, and lower abdominal wall and lower extremity. Therefore, careful genital examination —including the testicles/scrotum—can reveal common underlying causes such as skin malignancy of the scrotum , penile/scrotal lesions, chronic infection, or other local pathology that would explain a hard inguinal node.

Digital rectal examination assesses the prostate and rectum, whose lymphatic drainage is primarily to pelvic nodes rather than superficial inguinal nodes, making it less likely to identify the cause here. Palpation of liver or spleen looks for systemic malignancy/hematologic disease but is less likely to reveal the cause of a unilateral inguinal mass. Sexual history may suggest STI-related nodes, but these are typically tender and acute; a focused physical exam is more likely to reveal the etiology.

The patient demonstrates signs of asymmetric sensorineural hearing loss (SNHL). In Weber test, sound localizes to the better ear in SNHL. Air conduction > bone conduction on Rinne test bilaterally supports SNHL. Audiometry is the best next diagnostic step to quantify and characterize the hearing loss.

Toronto Notes 2023 – ENT, " Hearing Loss " :

“Audiometry is the first-line investigation to distinguish conductive from sensorineural hearing loss and to assess severity and frequency involvement.”

MCCQE1 Objectives (Medicine > ENT > 20-1):

“Candidates must know the approach to hearing loss and interpret Weber and Rinne tests to guide investigations such as audiometry.”

Imaging (A, C) is reserved for red flags such as unilateral persistent SNHL, which may later prompt MRI to rule out acoustic neuroma. Wax removal (D) is for conductive loss. Hearing aids (E) are management, not diagnostic, and come after audiologic evaluation.

When couples face infertility-related decisions—particularly involving donor insemination—psychosocial counseling is essential. A mental health consultation helps explore emotional concerns, expectations, and readiness for non-biological parenting.

Toronto Notes 2023 – Gynecology, “Infertility and ART”:

“Psychological counseling is recommended for couples considering donor gametes to address emotional, ethical, and identity issues before proceeding.”

MCCQE1 Objectives (ELOM > Reproductive Ethics > 83-1):

“Candidates must understand the ethical and psychosocial considerations of assisted reproductive techniques and provide appropriate referrals.”

Suggesting adoption or switching care dismisses valid concerns (B, C). Ovulation induction (D) does not address azoospermia.

This presentation is consistent with acute acalculous cholecystitis, often seen in critically ill or post-MI patients. If unresponsive to antibiotics, percutaneous cholecystostomy is the preferred next step in those who are poor surgical candidates.

Toronto Notes 2023 – General Surgery, “Hepatobiliary Disorders” Section:

“Acalculous cholecystitis occurs in critically ill patients and is often managed with percutaneous cholecystostomy if the patient is not a candidate for surgery.”

MCCQE1 Objectives (Surgery > 84-3: Biliary Disease):

“Candidates must be able to diagnose and manage acalculous cholecystitis. Management includes antibiotics and drainage via percutaneous cholecystostomy in unstable patients.”

Laparoscopic cholecystectomy (C) is standard but not suitable in acutely ill ICU patients. Broadening antibiotics (A) alone is insufficient after failure of initial therapy. ERCP (B) is for biliary obstruction or cholangitis. HIDA scan (E) is diagnostic, not therapeutic.

The key issue is patient confidentiality and informed consent for disclosure of identifiable information . Although the patient consented to having the image taken and uploaded to the medical record, consent for photography does not automatically extend to sharing the image with external parties , especially through informal channels. MCCQE objectives emphasize that physicians must obtain specific consent for disclosure , including the purpose, recipient, and method of transmission, unless the information is fully anonymized and non-identifiable. Clinical photographs may still be identifiable even if names are removed.

Texting the image, even if anonymized, risks breaching privacy and may not meet security standards. Simply refusing to share any photos is unnecessary because consultation is appropriate with consent. Even sending through a secure portal requires proper patient authorization for that specific disclosure.

Therefore, the appropriate next step is to contact the patient and obtain explicit consent to share the photograph with the identified physician for consultation, ensuring documentation of that consent and use of secure transmission methods thereafter.

Before proceeding with any virtual consultation, particularly by voice-only, it is essential to confirm the patient’s identity beyond name alone — for example, by verifying date of birth or health card number. This protects privacy and ensures medical confidentiality.

Toronto Notes 2023 – ELOM, Virtual Care Section:

“Virtual care must begin by verifying patient identity using at least two identifiers (e.g., full name and date of birth) to prevent disclosure of personal health information to unintended individuals.”

MCCQE1 Objectives – Ethical, Legal, and Professionalism > Virtual Care:

“The candidate must confirm patient identity and consent before initiating any virtual medical encounter, especially when video is not available.”

Option A (reason for visit) should follow identity confirmation. Option B (confirming primary care provider) is irrelevant to identity verification.

This patient presents with fever, chills, anorexia, and right upper quadrant (RUQ) pain several weeks after hospitalization for sigmoid diverticulitis . A key complication of intra-abdominal infections such as diverticulitis is portal pylephlebitis with hepatic abscess formation , due to bacterial spread via the portal venous system. MCCQE objectives emphasize recognizing liver abscess as a delayed complication of intra-abdominal sepsis, particularly when new RUQ pain and fever develop after an initial abdominal infection.

The most appropriate initial imaging test to confirm this diagnosis is ultrasound of the abdomen , which can detect hepatic abscesses and guide further management. CT abdomen is also highly sensitive, but among the listed options, ultrasound is most appropriate.

Chest and abdominal radiographs are nonspecific. HIDA scan evaluates cystic duct obstruction in suspected acute cholecystitis, which is less likely given the recent diverticulitis and systemic features. ERCP is used for biliary obstruction or ascending cholangitis, typically associated with jaundice.

Thus, abdominal ultrasound is most likely to confirm a hepatic abscess.

The most important factor in determining the surveillance interval in Barrett esophagus is the presence and grade of dysplasia (e.g., none, low-grade, high-grade). High-grade dysplasia requires more frequent monitoring or intervention due to the risk of progression to esophageal adenocarcinoma.

Toronto Notes 2023 – Gastroenterology, Barrett Esophagus:

“Surveillance intervals depend on histologic findings. No dysplasia: q3–5 years; low-grade: q6–12 months; high-grade: consider endoscopic resection or ablation.”

MCCQE1 Objectives – Internal Medicine > Gastroenterology:

“Candidates must identify the risk of progression in Barrett esophagus and apply appropriate surveillance strategies based on dysplasia.”

Length of the segment (A) may influence risk but not surveillance frequency alone. Other options (B, C, E) are less determinative.
