if a ventilated patient has inspiratory effort but the ventilator doesn't respond, what can be the reasons ? how can you solve this ?

Katie is a 7-month-old baby girl, the second child born to her parents. Her mother had a healthy, full-term pregnancy, and Nona’s birth weight was normal. She did not respond well to breastfeeding and was changed entirely to a formula based on cow’s milk at 4 weeks. Between 7 and 12 weeks of age, she was admitted to the hospital twice with a history of screaming after feeding, but was discharged after observation without a specific diagnosis. Elimination of cow’s milk from her diet did not relieve her symptoms; Katie’s mother reported that the screaming bouts were worse after Katie drank juice and that Katie frequently had gas and a distended abdomen. At 7 months she was still thriving (height and weight in the 97^th percentile) with no abnormal findings on physical examination. A stool sample was taken.

1. What is Katie’s diagnosis?

2. What is the cause of Katie’s symptoms?

3. What is needed in order for Katie to be able to feed normally?

4. What testing would be ordered to determine what is happening to Katie?

5. What is the treatment plan that Katie’s mother should follow?

the patellar knee-jerk reflex tests.

• Which nerve carries the afferent (sensory) signal? Which nerve carries the efferent (motor) signal?

• how did mental distraction and muscle activity in another area affect the patellar knee-jerk reflex? Is this what you expected to happen? In your own words try to explain your answers.

• how did fatigue affect the patellar knee-jerk reflex? Is this what you expected to happen?   In your own words try to explain your answers

After viewing the most common myths associated with stress from the APA website, discuss which concept you believe is the most misunderstood. Give support for your reasons (using your own research and sources for support).

Consider the different muscle fiber arrangement bundles (circular, pennate, parallel, and convergent). Briefly define each organization pattern and pick a muscle that would be defined in that category (i.e., circular arrangement orbicularis oris, parallel arragnement rectus abdominis, convergent pectoralis major, and pennate arrangement deltoid.) You must choose a different muscle for each category that was listed as an example to help you get started.

Next, pick one of the muscles you chose in your arrangement category. Identify a movement that would have that particular muscle be an agonist. Next chose an antagonist and a synergist muscle that would be involved in the movement you identified.

What is the relationship between the parts of the male reproductive organs.

What is the relationship between the parts of the female reproductive organs?

Medical terminology

At one point or another we have all bumped our heads, stubbed our toes or had a mosquito bite. We all know the result which is swelling or inflammation.

What causes the accumulation of fluids in tissues and how does this fluid become lymph?

1. Indicate which of the following best illustrates the concept of positive feedback? The concept of negative feedback? Make sure to justify your answer.

1. An increase in the concentration of H+ in blood causes an increase in H+ excretion in the urine.

2. An increase in the carbon dioxide concentration of the blood stimulates breathing, which increases the rate at which carbon dioxide is eliminated from the body.

3. Contractions of the uterus push the fetus against the cervix, which triggers release of oxytocin into the bloodstream. Oxytocin then stimulates stronger contractions of the uterus.

BJ. is a 5-year-old boy who has suffered from repeated upper respiratory infections since he was 16 months old. At 4 years of age, he was diagnosed with allergic asthma. The following winter, at age 5, he was admitted to the hospital twice for acute asthma with a secondary bacterial pulmonary infection.

At the second admission, a complete blood count, sputum culture, and immune status work-up were ordered.
