Correct Answer: C

Rationale: Family history of osteoporosis is a significant risk factor, as genetics play a key role in determining a person's risk for developing osteoporosis. Having a close relative, such as an aunt, with severe osteoporosis increases this woman's risk as there is a strong genetic component to the disease. Factors such as obesity (choice A), late menopause (choice B), and delayed menarche (choice D) do not directly increase the risk of osteoporosis, unlike having a familial history of the condition.

Correct Answer: B

Rationale: The clinical presentation described in the question is consistent with Candida vaginitis, also known as vaginal yeast infection. Candida vaginitis typically presents with a thick, white, curdy discharge that can be visualized on examination. The low pH of 1 is characteristic of Candida infection. The negative KOH whiff test and absence of an unusual smell help differentiate Candida vaginitis from other types of vaginitis.

Correct Answer: B

Rationale: Option B, briefy summarizing what you heard from the patient in the first 5 minutes and then trying to have her focus on one aspect of what she told you, is the best technique to facilitate a more focused and efficient interview. This approach acknowledges the patient's need to talk while also guiding the conversation towards more relevant topics. By summarizing at the beginning, you demonstrate that you are listening, and by redirecting the conversation to specific points, you can ensure that important issues are addressed within the time constraints of the appointment. It can help streamline the visit and prevent it from meandering off track due to the patient's chattiness.

Correct Answer: B

Rationale: The information provided - "The patient had a stent placed in the left anterior descending artery (LAD)" - is related to a medical procedure, specifically a surgical intervention involving the placement of a stent in a coronary artery. This information falls under the category of surgeries because it describes a surgical treatment to address a cardiovascular issue. It does not pertain to adult illnesses, obstetrics/gynecology, or psychiatric conditions, making option B the most appropriate category for this information.

Correct Answer: C

Rationale: The most likely explanation for Mrs. Lenzo noticing a 4-pound weight gain over just 2 days is fluctuations in body fluid. Our body weight can fluctuate throughout the day due to factors such as hydration levels, sodium intake, and hormonal changes. It is not physically possible to gain 4 pounds of actual body mass (e.g., fat or muscle) in such a short period of time by overeating or wearing different clothing. Additionally, if Mrs. Lenzo's scale is very accurate as mentioned, it is less likely that the weight gain is due to instrument inaccuracy. Therefore, the most plausible reason for the sudden weight gain is fluctuations in body fluid retention.
