<em>Maintain aseptic technique.</em>
Explanation:
Aseptic techniques involves following the practices and procedures that prevents or reduces contamination by pathogens. A burn patient can have his protective upper skin layer removed, exposing the vulnerable inner skin layer. The inner skin layer is susceptible to infection, and if infected, can lead to further medical complication, which might even end up fatal.<em> Aseptic technique involves the use of barrier to minimize contact between the patient and the medical personnel. Such barriers includes sterile gloves
, sterile gowns
, masks for the patient and healthcare personnel, and sterile drapes
. Sterile barriers should not have touched contaminated surface, and should be prepacked and sealed. Medical instruments should be sterilized too.</em>
Answer: b. False
Explanation:
The one repetition maximum or (1RM) test is a test which is used to measure the strength capacity of the individuals typically in a non-laboratory environment. It is define as the maximum weight that an individual can lift only with one repetition and with the use of the correct technique. This is basically done to check the strength capacities, strength imbalances and also to evaluate the effectiveness of a particular training programmes.

Answer:
The correct answer will be option B.
Explanation:
Blood pressure represents the pressure of the blood in the major arteries of the body.
This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.
The blood pressure decrease in the artery due to ventricular diastole during which ventricles relaxes. This lower number of blood pressure is known as diastolic blood pressure which is 80 mm of Hg.
Thus, option B is the correct answer.
