A 52-year-old woman with a BMI of 31 is diagnosed with osteoarthritis of the knee. The nurse practitioner (NP) instructs the woman that weight loss will help minimize both pain and functional loss. Which of the following most closely explains the NP's advice to lose weight?
Weight loss is encouraged for the overall health of the patient because it reduces the chance of developing diabetes and other cardiometabolic issues
Each pound of weight loss can decrease the load across the knee 3 to 6-fold
Weight loss can reduce cardiovascular strain
Weight loss can reduce the chance for a fall, which might lead to additional damage to the knee joint
The Correct Answer is B
Choice A reason: While true, this choice is a general health benefit and does not directly explain the reduction in knee pain or functional loss.
Choice B reason: This choice is correct because mechanical load on the knee joint increases disproportionately with body weight. Even a small amount of weight loss significantly reduces joint stress, thereby improving pain and function in osteoarthritis.
Choice C reason: Reducing cardiovascular strain is beneficial but does not directly impact knee joint load or osteoarthritis symptoms.
Choice D reason: Preventing falls is important but is an indirect benefit; the primary mechanism for pain reduction is decreased mechanical load on the joint.

Choice A reason: Dissociative identity disorder is characterized by the presence of two or more distinct identities or personality states and amnesia for daily events, which aligns with the patient’s symptoms.
Choice B reason: Adjustment disorder involves emotional or behavioral symptoms in response to a stressor but does not include dissociation or multiple identities.
Choice C reason: Schizotypal personality disorder involves eccentric behavior, perceptual distortions, and odd beliefs but does not include distinct identities or memory gaps.

Correct Answer is C
Explanation
Choice A reason: Guided imagery is a mind-body intervention using mental visualization techniques and does not involve direct manipulation of the body.
Choice B reason: Meditation focuses on mindfulness and relaxation techniques without physical manipulation of muscles or joints.
Choice C reason: Reflexology is a manipulative body-based therapy that involves applying pressure to specific points on the feet, hands, or ears to stimulate healing and relaxation in corresponding body parts.
Choice D reason: Yoga combines physical postures, breathing, and meditation. While it involves the body, it is primarily classified as movement-based or mind-body therapy rather than strictly manipulative body-based therapy.
