Answer:
Apprehension sign
Explanation:
The sign of apprehension is a provocative test to identify patellar instability. In this test the client is sitting with the quadriceps relaxed and the knee is placed in extension. Then the patella is displaced laterally and the knee flexed at 30 °. If there is instability the client will put his hand avoiding the continuity of the test, because he will feel pain. In addition, if patellar instability exists during this test, the client will contract the quadriceps for fear of dislocating the patella and will verbally report the pain as: "stop if you won't dislocate my knee", "my patella will leave from the place, stop! "
The correct answer is 920IU of vitamin D.
International Unit (IU) is a unit of measurement used widely to quantify hormones, vitamins, blood products and several medications. It refers to the mass or volume of a substance but varies depending on the substance which is being measured and its biological activity.
Regarding Vitamin D, 1 microgram (μg) of vitamin D is equivalent to 40IU. Since 6 oz of baked salmon contains 23 μg of vitamin D, Andy's vitamin D intake will be 920IU (23 μg * 40IU = 920IU).
