A 15-year-old high school sophomore and her mother come to your clinic because the mother is concerned about her daughter's weight. You measure her daughter's height and weight and obtain a BMI of 19.5 kg/m2. Based on this information, which of the following is appropriate?

Correct Answer: B

Rationale: Step 1: Calculate BMI: BMI = weight (kg) / height (m)^2 BMI = 19.5 kg / (1.65 m)^2 BMI = 19.5 kg / 2.72 m^2 BMI = 7.17 Step 2: Interpretation of BMI: BMI of 19.5 falls within the normal range (18.5-24.9) for a 15-year-old. Step 3: Rationale for Correct Answer (B): The correct answer is to reassure the mother that her daughter's BMI of 19.5 is normal for her age. There are no indicators of anorexia or obesity based on the BMI calculation. Step 4: Summary of Incorrect Choices: A: Referring to a nutritionist and psychologist for anorexia is incorrect as the BMI is within the normal range. C: Providing exercise information for obesity is incorrect as the BMI does not indicate obesity. D:

Correct Answer: B

Rationale: The correct answer is B: Leverage technology to ensure communication. Your hospital recently invested in video interpreter services. Rationale: 1. Utilizing technology like video interpreter services ensures accurate and real-time communication, overcoming language barriers effectively. 2. Video interpreter services provide professional interpreters who are trained in medical terminology, ensuring accurate transmission of information. 3. It maintains patient confidentiality and adheres to HIPAA regulations by using secure communication platforms. 4. It promotes cultural competency and patient-centered care by facilitating understanding and building trust with the patient. Summary of other choices: A: Identifying a friend or family member can compromise patient confidentiality and accuracy of interpretation. C: Using gestures and simple words may lead to miscommunication, misunderstanding, and potential medical errors. D: Delaying care by calling another floor for a Spanish speaker can jeopardize timely treatment for the patient's chest pain.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Froment's sign is a test for ulnar nerve dysfunction. 2. Positive Froment's sign occurs when a person uses their thumb to hold onto an object due to weakened adductor pollicis (innervated by ulnar nerve). 3. Therefore, a positive Froment's sign hints at ulnar nerve injury. Summary: A: Incorrect - Median nerve does not relate to Froment's sign. B: Incorrect - Radial nerve does not relate to Froment's sign. C: Correct - Ulnar nerve is associated with a positive Froment's sign. D: Incorrect - Musculocutaneous nerve does not relate to Froment's sign.

Correct Answer: A

Rationale: Rationale for Choice A: The ACL prevents backward sliding of the femur by attaching from the back of the femur to the front of the tibia. When the knee is flexed, it prevents the femur from sliding backward on the tibia, providing stability. Summary of other choices: B: Incorrect, as the ACL primarily limits anterior translation of the tibia on the femur, not external rotation. C: Incorrect, as the ACL tightens with extension and loosens in flexion to provide stability. D: Incorrect, as ACL deficiency can lead to instability and increased pressures on the posterior menisci, not the anterior menisci.

Correct Answer: D

Rationale: The correct answer is D because plica syndrome of the knee refers to an extension or vestigial structure of the protective synovial capsule of the knee becoming irritated or inflamed, leading to anterior knee pain and weakness. This is the most accurate description of the condition. Choice A is incorrect because plica syndrome is not caused by a duplicated meniscus. Choice B is also incorrect as it describes knee pain and weakness related to rheumatoid arthritis, not plica syndrome. Choice C is incorrect as it refers to a synovial fold in the femorotibial joint, which is not specific to plica syndrome.
