3) Based on your understanding of nitrogen balance identify which condition exists in each of the following examples:
An anorexic patient is rapidly losing skeletal muscle tissue
A weight lifter who is increasing lean body mass
A pregnant woman proceeding through a healthy pregnancy
A serious burn victim who is receiving protein supplements but still losing weight
4) Jacob has been working a much longer shift than he expected and is very hungry. He is slightly hypoglycemic; luckily, he has no pathology that prevents his body from reacting appropriately. Predict what hormonal changes can be expected in Jacob in response to his low blood glucose levels, the effect that hormone will have within the body, and the specific fuel source that his cells will utilize for their metabolic needs in response to this situation.

you decided to take a break after grading all of the final exams for our course and took a much-needed vacation. Unfortunately, he went surfing and was attacked by a shark that ate his arm. you, an expert one-handed swimmer, made his way back to shore. During his swim back,
Group of answer choices
1. you sympathetic nervous system stimulated the smooth muscle around his arterioles to contract to increase his mean arterial pressure
2. you pondered your history of making poor choices and decided is safer than surfing in shark infested waters
3. your sympathetic nervous system stimulated his heart to increase cardiac output to increase his mean arteriole pressure.
4. your circulating levels of vasopressin increased to promote the insertion of aquaporins into his collecting ducts to reabsorb as much water as possible.
5. three or four of these answers (depending on whether you lost too much blood to his brain to affect his ability to think properly).

Three medical doctors, each specializing in different areas, agree to set up a practice together. Suggest three (3) medical devices (one for each of the areas of specialization but not necessarily to be used exclusively in one area) that the doctors may wish to purchase.
For each device,
i) justify why it is necessary for, and how it can be used in, the joint practice;
ii) explain why it is classified as a medical device;
iii) state, with justification, at least two different ways of classifying the device (for
example, diagnostic or therapeutic, and so on);
iv) identify the measurand and the source of the measurand.
b) Discuss three (3) factors for consideration in the
procurement of these devices. Part of
the discussion must focus on whether a cross-functional team
approach to the procurement process is necessary.
Note:
You will need to select the areas of specialization of the doctors
before suggesting devices. Devices of Low Risk are not to be used
in answering the question.
