A scientist adds 5 mcg of the mineral cadmium to the daily diet of 100 4-week-old laboratory mice. After twelve weeks, the researcher weighs and takes blood samples from each mouse. According to her findings, the mice lost weight during the 12-week period and they have abnormal levels of certain hormones in their blood. Based on this information and your knowledge of scientific research, what would you tell the researcher about her findings?
A. She needs to conduct more tests on the animals' blood, because her findings are
incomplete.
B. The findings are not meaningful or valid because of the way she designed her study.
C. Her results are very interesting and she should report her findings to nutrition scientists, so
they can repeat her study and confirm the results.
D. The findings need to be summarized in a research article for submission to a peer-reviewed
nutrition journal.
Answer:
B. The findings are not meaningful or valid because of the way she designed her study.
Explanation:
In a scientific experiment, a control group is a group of individuals/subjects that do not receive the experimental treatment. The control group is used to determine how much of an impact a treatment (in this case, cadmium intake) has on the variables being examined in the participants who are subjected to the experimental treatment. In any experiment, it is imperative to include a control group in order to validate experimental results. In this case, it is not possible to confirm that the loss of weight and abnormal hormone levels are due to cadmium uptake because only a control group would elucidate the contribution of cadmium intake on the variables being tested.

In two sentences elaborate possible consequences if an employee does not
meet all the requirements in an employment contract.
Answer:
Two possible consequences that an employee does not meet all the requirements in an employment contract are, on the one hand, the eventual loss of the job and, on the other, a less possible readjustment of tasks for the employee. Thus, if this does not meet the requirements of the company, it is most likely to dispense with its services through firing him, either (if it is an employee with a certain history in the company, or has characteristics that make it necessary for it) modifying their job responsibilities.
Below is a list of body systems- complete the following: - • Sensory function • Cardiac function • Respiratory function • Neurological function • Musculoskeletal function • Genitourinary function • Endocrine function • renal function • skin integrity a. List 2 age related physiological changes for each system b. Discuss how these identified changes can affect the client’s ability to perform activities of daily living. Age-related Physiological changes Give two examples Effect on ADLs (client’s daily functioning) Give one example
Answer:
Physiological changes occur with aging in all organ systems. The cardiac output decreases, blood pressure increases and arteriosclerosis develops. The lungs show impaired gas exchange, a decrease in vital capacity and slower expiratory flow rates. The creatinine clearance decreases with age although the serum creatinine level remains relatively constant due to a proportionate age-related decrease in creatinine production. Functional changes, largely related to altered motility patterns, occur in the gastrointestinal system with senescence, and atrophic gastritis and altered hepatic drug metabolism are common in the elderly. Progressive elevation of blood glucose occurs with age on a multifactorial basis and osteoporosis is frequently seen due to a linear decline in bone mass after the fourth decade. The epidermis of the skin atrophies with age and due to changes in collagen and elastin the skin loses its tone and elasticity. Lean body mass declines with age and this is primarily due to loss and atrophy of muscle cells. Degenerative changes occur in many joints and this, combined with the loss of muscle mass, inhibits elderly patients' locomotion. These changes with age have important practical implications for the clinical management of elderly patients: metabolism is altered, changes in response to commonly used drugs make different drug dosages necessary and there is need for rational preventive programs of diet and exercise in an effort to delay or reverse some of these changes.

Your Gram stain is complete and correct which of the following would apply to the image you see
Answer:
hi how are you
Explanation:
You can observe gram-negative bacilli on this field and You can observe gram-positive cocci on this field would apply to the image you see. Hence, options A and D are correct.
What is gram-negative bacilli?The majority of currently used antibiotics as well as a number of other drugs are losing their effectiveness against gram-negative bacteria. These bacteria have the capacity to transmit genetic material that makes it possible for other bacteria to develop drug resistance, and they are naturally inclined to come up with new ways to do so.
Gram-negative organisms that are frequently isolated include Pseudomonas, Klebsiella, Proteus, Salmonella, Providencia, Escherichia, Morganella, Aeromonas, and Citrobacter. Gram-positive bacteria can live with Gram-negative bacteria or even be the dominant organisms in some situations.
Gram-negative bacteria have a high level of antibiotic resistance, making them one of the most important public health concerns in the world.
Thus, options A and D are correct.

A patient presents with a healed fracture of the left ankle. The patient was placed on the OR table in the supine
position. After satisfactory induction of general anesthesia, the patient’s left ankle was prepped and draped. A small
incision about 1 cm long was made in the previous incision. The lower screws were removed. Another small incision was
made just lateral about 1 cm long. The upper screws were removed from the plate. Both wounds were thoroughly irrigated
with copious amounts of antibiotic- saline solution. Skin was closed in a layered fashion and sterile dressing applied.

You are treating a patient in shock. Explain the physiologic/pathophysiologic reason you see
each of the following signs and symptoms. The answers do not have to be long but must
adequately and accurately describe the mechanism that causes each sign to appear.
Answer:
Pale, cold skin and high breathing rate.
Explanation:
Pale, cold skin is the first sign of shock and the reason behind this pale colour is the decrease in the blood flow. Pale skin results from a decrease in blood flow to the body due to shock. It may also occurs from a reduction in the number of red blood cells which is also called anemia. The rapid breathing is also occurs due to shock because the body needs oxygen in large amount to restore the normal conditions of the body.
