Trauma Glasgow 7 is caused by failure to recognize and control the amount of haemorrhage. Immediate priority which nurse takes is to manage large volume of blood loss. Assessment of airway stability and patency should be performed and airway management intuited should be there as needed unless the patient is in cardiac.
Primary survey is the initial management and assessment of trauma patient. The primary purpose of the pivotal study is to treat actual and detect life threats and prevent complication from the injury. The time the patient arrives at the emergency department, full non-invasive monitoring should be applied to the patient.
The primary survey which is taken to the trauma patient include ABCDE
Airway. It is to check for any airway obstruction.
Breathing. Check for haemothorax.
Circulation. Check for circulation of blood.
Disability.

Answer: A. Zidovudine (Retrovir) and emtricitabine (Emtriva)
Explanation:
Basic postexposure prophylaxis (PEP) therapy typically includes treatment with one of these combinations of pharmacologic agents:
Zidovudine (Retrovir) and emtricitabine Emtriva),
Lamivudine (Epivir) and tenofovir (Viread), or
Tenofovir (Viread) and emtricitabine (Emtriva)
If the accidental exposure is especially severe, a third agent may be included.
The answer is C
Plasmids are conferred through horizontal gene transfer in bacteria. The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.
Answer:
Approximately 6944 glucose residues are added enzymatically per second
Explanation:
Cellulose is the main structural polysaccharides in plants. It is composed of unbranched glucose monomer units linked to each other by beta 1-4 glycosidic bonds.
The cell wall and stem of plants cells are composed of cellulose fibers. They provide rigidity and support to the plant.
In the given bamboo plant, the enzymatic addition of glucose units to the growing cellulose fiber chains results in the phenomenal growth rate of the bamboo stem.
Since each glucose unit contributes ~0.5 nm to the length of a cellulose molecule, number of glucose units required for daily growth is calculated as follows:
0.5 nm = 10⁻⁹
0.3 m/0.5 x 10⁻⁹ m = 600000000 units of glucose per day
Number of seconds in a day = 24 * 60 * 60 = 86400 seconds
Number of glucose residues added per second = 600000000/86400
Number of glucose residues added per second = 6944.4 glucose molecules per second
Therefore, approximately 6944 glucose residues are added per second
GMOs may lead to the use of different herbicides or pesticides is a true statement.
Explanation:
The GMO crops leads to growth of weeds that can resist herbicides other than for which the GMO is genetically-modified. The over-usage or over-reliance on herbicide-resistant GMO (Genetically modified organisms) crops had given way to the growth of such superweeds.
The main characteristic of these superweeds is resistance to the herbicides or the weedkillers leading to infestation of farmlands by these superweeds Hence farmers need to add different herbicides or pesticides to control the growth of superweeds.
