Mrs. R. is a 92-year-old retired teacher who comes to your clinic accompanied by her daughter. You ask Mrs. R. why she came to your clinic today. She looks at her daughter and doesn't say anything in response to your question. This is an example of which type of challenging patient?

Correct Answer: C

Rationale: The correct answer is C: Silent patient. Mrs. R.'s lack of response to the question despite being asked directly indicates she is a silent patient. This type of patient may be non-communicative due to various reasons such as anxiety, cognitive impairment, or being passive in decision-making. In this case, Mrs. R. may be relying on her daughter to communicate for her. The other choices are incorrect because Mrs. R. is not talkative, angry, or necessarily hearing-impaired based on the information provided. It is important for healthcare providers to recognize and adapt their communication strategies to effectively engage with silent patients.

Correct Answer: D

Rationale: The correct answer is D because facing the client while leaning slightly forward shows active listening and engagement, conveying respect and attentiveness. This posture encourages open communication and trust-building. Choice A is incorrect as the visitors' lounge may not provide privacy. Choice B may invade personal space and affect rapport. Choice C may not be appropriate as touch should only be used if culturally acceptable and with consent.

Correct Answer: D

Rationale: The correct answer is D because in supine position with knees flexed to 90 degrees and feet flat on the table, the right knee being anterior to the left knee indicates that the right femur is longer. This is due to the natural anatomical alignment of the femurs in relation to the knees. The other choices (A, B, C) do not accurately reflect the correct method of determining femur length discrepancy in this specific position. Choice A and B focus on the height of the knees, which may not be an accurate indicator of femur length. Choice C refers to the anterior positioning of the left knee, which is not a reliable indicator of femur length discrepancy.

Correct Answer: C

Rationale: The correct answer is C because the popliteus muscle externally rotates the femur on the tibia during a closed chain movement, such as when the foot is fixed on the ground and the leg rotates. This action helps unlock the knee by initiating the screw-home mechanism, allowing for smooth knee extension. A: Incorrect because the popliteus muscle does not internally rotate the femur on the tibia during an open chain movement. B: Incorrect because the popliteus muscle does not externally rotate the tibia on the femur during an open chain movement. D: Incorrect because the popliteus muscle does not internally rotate the tibia on the femur during a closed chain movement.

Correct Answer: C

Rationale: To measure for leg length discrepancy accurately, you should measure from the Anterior Superior Iliac Spine (ASIS) to the Medial Malleolus. This is because the ASIS is a reliable and consistent bony landmark for measurement, and the medial malleolus is a stable reference point at the ankle joint. Measuring from ASIS to Medial Malleolus ensures that the entire length of the leg is accounted for, providing an accurate assessment of any potential length difference between the two legs. This measurement technique is commonly used in clinical practice and research studies to assess leg length inequality. Summary: A: Incorrect - Does not account for the full length of the leg. B: Incorrect - PSIS is not commonly used as a reference point for leg length measurement. C: Correct - ASIS to Medial Malleolus provides an accurate measurement of leg length discrepancy. D: Incorrect - PSIS is not commonly used for measuring leg length, and measuring
