Correct Answer: A

Rationale: Rheumatoid arthritis is a systemic autoimmune disease that primarily affects the joints. It commonly presents with pain, swelling, and stiffness in multiple small joints such as those in the hands, wrists, and feet. It is more prevalent in females in their 30s to 50s. Rheumatoid arthritis is characterized by chronic inflammation of the synovial membrane, leading to joint damage and deformities over time. Laboratory tests showing elevated inflammatory markers, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), along with positive rheumatoid factor and anti-cyclic citrullinated peptide (anti-CCP) antibodies, can help in confirming the diagnosis of rheumatoid arthritis.

Correct Answer: B

Rationale: In respiratory distress, the skin between the ribs moves inward with inspiration, a phenomenon known as retractions. This is a sign of increased work of breathing as the body tries to pull in more air due to difficulty in breathing. The inward movement of the skin between the ribs indicates that the individual is not able to generate enough negative pressure in the chest cavity to inhale properly. This can be seen in conditions such as asthma, pneumonia, or other respiratory issues. Skin retractions are a concerning sign and may indicate a severe respiratory compromise that requires immediate medical attention. The other options listed do not specifically describe a characteristic of respiratory distress.

Correct Answer: A

Rationale: The presence of a firm and immobile mass felt against the bowel wall during a rectal examination is concerning for a potential malignancy, such as colon cancer. Other conditions such as hemorrhoids or anal fissures are typically not associated with a mass that is firm and immobile. The "Valve of Houston" is a term that does not pertain to this scenario and is not a recognized medical entity. Therefore, the most likely diagnosis based on the given information is colon cancer, and further evaluation such as a colonoscopy would be warranted for definitive diagnosis and management.

Correct Answer: C

Rationale: A "red flag" regarding patients presenting with a headache is their age being over 50. This is because new-onset or persistent headaches in individuals over 50 may raise concerns about underlying serious conditions such as temporal arteritis, brain tumor, or other vascular issues. It is important to thoroughly evaluate and consider these possibilities in older patients with headaches to ensure appropriate management and timely intervention.

Correct Answer: A

Rationale: Anisocoria refers to a condition where the pupils are of unequal size. Pathologic causes of anisocoria can include conditions such as Horner's syndrome. Horner's syndrome is a rare disorder caused by damage to the sympathetic nerves of the face and eye. Symptoms can include a constricted pupil (miosis), drooping of the upper eyelid (ptosis), and decreased sweating in the affected area. This results in anisocoria, where the affected pupil is smaller than the unaffected pupil. Other options listed (B-D) do not typically lead to pathologic anisocoria.
