A patient presents with multiple, hyperpigmented, velvety plaques in flexural areas such as the axillae and neck. The lesions are associated with obesity and insulin resistance. Which of the following conditions is most likely responsible for this presentation?
- A. Acanthosis nigricans
- B. Seborrheic keratosis
- C. Dermatofibroma
- D. Epidermal nevus
Correct Answer: A
Rationale: Acanthosis nigricans is a skin condition characterized by multiple, hyperpigmented, velvety plaques typically seen in flexural areas such as the axillae, neck, and groin. These lesions are often associated with obesity and insulin resistance. The appearance of acanthosis nigricans is distinct from other skin conditions such as seborrheic keratosis, dermatofibroma, and epidermal nevus. Acanthosis nigricans is commonly seen in conditions like obesity, type 2 diabetes, and metabolic syndrome due to the insulin resistance that leads to the overgrowth of keratinocytes.

On the question as to which of the following are the effects of AIDS on pregnancy, one teenager cited a wrong answer which was ________.
- A. Mild weight loss
- B. Repeated abortion
- C. Prematurity
- D. Infertility
Correct Answer: B
Rationale: The effects of AIDS on pregnancy do not generally include repeated abortion as a direct consequence. AIDS can impact pregnancy by increasing the risk of complications such as premature birth, low birth weight, and potential transmission of the virus from mother to child. Infertility can also be a concern, but repeated abortion is not a common effect of AIDS on pregnancy. It is important to provide accurate information about the effects of AIDS on pregnancy to ensure proper understanding and support for individuals affected by this condition.

- A. cohesive
- B. driven
- C. shared goa l
- D. Sense of mission

While being driven, having shared goals, and a sense of mission are important characteristics of a strong team, cohesion is the foundation that holds the team together and allows these other factors to thrive.
A patient presents with sudden-onset severe headache, vomiting, and altered mental status. Imaging reveals a hyperdense lesion within the brain parenchyma, suggestive of acute bleeding. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Ischemic stroke
- B. Subdural hematoma
- C. Intracerebral hemorrhage
- D. Subarachnoid hemorrhage
Correct Answer: C
Rationale: Intracerebral hemorrhage is characterized by bleeding directly into the brain parenchyma, leading to the sudden onset of severe headache, vomiting, altered mental status, and neurological deficits. The hyperdense lesion seen on imaging is caused by the presence of blood within the brain tissue. This condition is often associated with hypertension and can be life-threatening if not promptly diagnosed and managed. Subdural hematoma is an accumulation of blood between the brain and its outermost covering (dura mater), typically presenting with a slower onset of symptoms compared to intracerebral hemorrhage. Subarachnoid hemorrhage involves bleeding into the space between the arachnoid membrane and the pia mater (subarachnoid space), commonly caused by the rupture of an aneurysm. Ischemic stroke results from the blockage of a blood vessel supplying the brain, leading to a lack of oxygen and nutrients to
A 28-year-old woman presents with cyclic pelvic pain, dysmenorrhea, and infertility. On pelvic examination, tender nodules are palpated along the uterosacral ligaments. Which of the following conditions is most likely to be responsible for these findings?
- A. Polycystic ovary syndrome (PCOS)
- B. Endometriosis
- C. Adenomyosis
- D. Leiomyomas (uterine fibroids)
Correct Answer: B
Rationale: Endometriosis is a chronic gynecologic condition characterized by the presence of endometrial-like tissue outside the uterus, commonly on structures within the pelvis. The classic symptoms of endometriosis include cyclic pelvic pain, dysmenorrhea (painful periods), and infertility. On pelvic examination, tender nodules or masses may be palpated along the uterosacral ligaments. These nodules are often referred to as "endometriotic implants" or "chocolate cysts." Endometriosis can cause inflammation, scarring, and adhesions in the pelvis, leading to symptoms such as pain and infertility. Polycystic ovary syndrome (PCOS) is characterized by ovarian dysfunction and hormonal imbalances, often leading to irregular periods and symptoms related to excess androgens. Adenomyosis is the presence of endometrial tissue within the myometrium of the uterus, leading
Which of the following give meaning and context to the message?
- A. Process
- B. Context
- C. Phrases and sentences
- D. Thoughts and feelings
Correct Answer: B
Rationale: In order to understand and interpret a message accurately, it is essential to consider the context in which it was delivered. Context provides the necessary background information, setting, and circumstances that give meaning and relevance to the message being communicated. Without context, it can be challenging to fully grasp the intention and significance of the communication. While the other options (process, phrases and sentences, thoughts and feelings) play roles in communication, it is the context that ultimately helps to give meaning and context to the message being conveyed.
