Correct Answer: B

Rationale: Plantar fasciitis is the correct answer. It is characterized by inflammation of the plantar fascia, leading to heel pain, especially in the morning. The plantar fascia is a band of tissue that connects the heel bone to the toes. The pain is usually worse with the first steps after resting. Achilles tendinitis involves inflammation of the Achilles tendon, which connects the calf muscles to the heel bone, causing pain at the back of the heel and ankle. Morton's neuroma is a condition involving a thickening of tissue around a nerve in the ball of the foot, leading to sharp, burning pain in the toes. Stress fracture of the calcaneus refers to a small crack in the heel bone due to repetitive stress or overuse, resulting in heel pain that may worsen with activity, but not specifically with the first steps in the morning.

Correct Answer: B

Rationale: The correct answer is B: IgA. In multiple myeloma, there is a proliferation of abnormal plasma cells, leading to a decrease in normal antibody production. IgA is the most abundant immunoglobulin in mucosal secretions and plays a crucial role in mucosal immunity. Therefore, a deficiency in IgA is common in patients with multiple myeloma. IgG is the most abundant immunoglobulin in the blood and is typically less affected in multiple myeloma. IgM is the first antibody produced in response to an infection and is less likely to be deficient in this case. IgE is primarily involved in allergic responses and is not typically affected in multiple myeloma.

Correct Answer: D

Rationale: The correct answer is D: Feeling of hopelessness. Adolescents who feel hopeless are at a higher risk of attempting suicide due to a lack of belief in positive outcomes. This feeling can lead to a sense of being trapped and unable to see a way out. Depressed mood (A) can contribute to suicide risk, but specifically feeling hopeless is a more direct predictor. Feeling of euphoria (B) and joyful mood (C) are actually less likely to be associated with suicide attempts, as they may temporarily mask underlying issues or provide a sense of distraction. Hopelessness is a key psychological factor that can lead to suicidal thoughts and behaviors in adolescents.

Correct Answer: C

Rationale: The correct answer is C because an open forum to solicit questions related to the topic under discussion is a common practice after a lecture presentation. This allows for clarification and deeper understanding. Choice A is incorrect as evaluation usually comes after the lecture. Choice B is incorrect because the Q&A portion typically focuses on the lecture content only. Choice D is incorrect as cracking humorous anecdotes is not a standard practice after a lecture.

Correct Answer: A

Rationale: The correct answer is A: Empiric antibiotic therapy directed against common pathogens. This is recommended for managing PID because it helps treat the infection and prevent complications. Antibiotics target the underlying bacterial infection causing PID. Surgical exploration (B) is not the initial treatment for PID. Hormonal therapy (C) is not indicated for PID management. Symptomatic treatment with NSAIDs (D) can help with pain but does not address the infection itself.
