Answer:

The correct answer will be:

1.  Acetylcholine binds to receptors on the motor end plate

2. Chemically-regulated ion channels open, causing depolarization

3  End plate potentials trigger action potential(s).

4. Transverse tubules convey potentials into the interior of the cell

5. Ca++ is released from the sarcoplasmic reticulum

6. Ca++ binds to troponin, pulling on tropomyosin

7. Binding sites on actin are uncovered, allowing myosin to bind and carry out power strokes

8. Force increases.

9. Ca++ is pumped (re-sequestered) into the sarcoplasmic reticulum

10.  Force decreases.

Explanation:

The muscle contraction is a highly controlled mechanism which begins at the neuromuscular junction with the release of the acetylcholine neurotransmitter. This neurotransmitter causes the depolarization of the membrane by binding to the receptors of the motor end plate which generates an action potential. This action potential is transmitted via T-tubules from sarcolemma to the sarcoplasmic reticulum.  

The sarcoplasmic reticulum releases calcium ions which binds to the troponin protein. This troponin removes the protein tropomyosin from the actin causing the rotation of the tropomyosin exposing the binding sites for myosin. The myosin binds to the actin using energy from the ATP which pulls the actin causing contraction. Another ATP binds the myosin head which weakens the bond between myosin and actin which releases the myosin which decreases the force between them decreases and the muscles relax.

lbvjy [14]

1. What ethical pressures are present in this scenario?

In this scenario, Sally faces an ethical dilemma because she is caught between two entities that she really values. On the one hand, Sally values her job and the company, and she does not want to cause them unnecessary damage. On the other hand, Sally cares about the community, and she wants people to be safe. Sally appears to find it difficult to reconcile these concerns. Moreover, regardless of her decision, Sally is likely to damage one of the two entities she cares about.

2. If you could advise Sally about how to manage ethics in this situation, what would you say? Explain.

I would say that Sally should contact the newspaper and make the story public. Sally has already contacted the company, and she gave them a chance to rectify their mistakes. However, they decided not to take responsibility for their actions. This is their decision, and it makes them responsible for whatever punishment they receive. Moreover, Sally knows that this practice is illegal, and as a responsible citizen, she has to follow the law.

3. What potential risks does your recommendation pose if Sally were to follow your advice?

Sally could face many risks because of this decision. The company is likely to know that she is responsible for making the story go public. This could cost Sally her job. Depending on the seriousness of the situation, the company might close permanently, leaving many people unemployed, including Sally herself.

Pressure Ulcer Risk and Prevention Practices in Pediatric Patients: A Secondary Analysis of Data from the National Database of N
kicyunya [14]

To depict the recurrence of weight ulcer hazard appraisal in pediatric patients and weight ulcer avoidance intercession utilize by and large and by healing center unit sort, a clear auxiliary examination was performed of information submitted to the National Database for Nursing Quality Indicators (NDNQI) for at slightest 3 of the 4 quarters in 2012.

Significant information on weight ulcer hazard from 271 clinics over the Joined together States extricated from the NDNQI database included understanding skin and weight ulcer hazard evaluation on confirmation, time since the final weight ulcer hazard appraisal, strategy utilized to survey weight ulcer hazard, and chance status.

Extricated information on weight ulcer anticipation included skin evaluation, pressure-redistribution surface utilize, schedule repositioning, wholesome bolster, and dampness administration. These information were organized by unit sort and consolidated with information on clinic characteristics for the investigation.

The frequency of prevention intervention use among those at risk ranged from 99.2% for skin assessment to 70.7% for redistribution surface use.
