Care must be taken when squeezing the pipet bulb on the filter pipet. Too much pressure might cause the filter to leak or fall off. Add about 2 mL of fresh tert-butyl methyl ether to the solid in the RB flask, warm briefly, let the solids settle for a minute, and pipet the liquid to the centrifuge tube as before. Again allow the solids to settle briefly in the centrifuge tube, then filter the liquid through the pressure filtration apparatus, into the same 25 mL Erlenmeyer flask. Doing a rinse such as this helps to ensure that any trimyristin that was left behind in the RB flask and centrifuge tube is not lost, thereby helping to ensure that
Over-the-counter ibuprofen or acetaminophen can help relieve pain and swelling. Do NOT give children under 12 aspirin. Once the skin has cooled, moisturizing lotion also can help. 6. Minor burns will usually heal without further treatment.
Then proceed to decolorize with 95% ethanol until the ethanol running off the slide is clear. Briefly rinse with distilled water. Counter-stain with safranin (secondary stain) for 1 minute then rinse with distilled water and gently blot dry with a paper towel. Lastly observe slide using oil immersion with the 100x
To begin, you should choose an arm and tie your tourniquet 2- 3 inches above the anticubital fossa (the bend of the arm). Next, Palpate for a vein by using your first finger. If no veins are palpable, have the patient make a tight fist and feel for a vein again, or try the other arm. If the vein feels suitable, disinfect the area with an alcohol wipe. It is important not touch the site again to prevent contamination unless you have
The aspirator was turned to medium high, and then the copper was poured onto wetted filter paper. Using distilled water to remove all copper from the beaker. Once completely on filter paper 6mL of acetone was added to the copper to help dry it out. The filter paper was then removed and set down to dry completely. Once dry the filter paper was weighed with the copper on it and subtracted from the original weight to see the amount of copper left after
BC405 The procedure for exposure to blood (1) When a patron or licensee is exposed to blood by scissors cut, razor cut, needle stick, laceration or other exposure to broken skin or a mucous membrane, the licensee shall stop, thoroughly was the exposed area or wound on the patron’s body with soap and water, and disinfect the exposed area or wound with a topical antiseptic such as iodine, 70% isopropyl alcohol, or 6% stabilized hydrogen peroxide or equivalent. In the case of mucous membrane exposure, the licensee shall wash the affected area with plenty of water. (2) A Licensed establishment shall post a written protocol describing the procedure for unintentional conspicuous to licensee occupational exposure to bodily fluids described in sub (1). The protocol shall be posted in a place conspicuous to licensee. BC406 Precautionary procedures (1) A licensee shall cover all abrasions, oozing or open lesions or wounds on his or her hands or forearms prior
Patient cleaned cut with peroxide and applied a Band-Aid, when he should have washed it thoroughly with soap and water and applied an antibacterial cream every day. Cover with a bandage and change it every day until a scab forms. And watch for redness, pain, drainage, or other signs of infection. (www.nlm.nih.gov, Linda J. Vorvick, MD) The fish tooth led to an infection, because seawater is full of infectious microorganisms. All wounds, even minor cuts and scrapes, should be treated as contaminated and potentially serious and should be carefully cleaned to prevent infection.
Bring the contents of the distillation flask to a gentle reflux (i.e., vapors are condensing in the first ¼ to 1/3 of the vertical condenser and dripping constantly back into the flask below). Maintain this reflux for 10 minutes, then increase the heat in order to distill the liquid into the collection flask, then the column, and even the distillation head with aluminum foil (shiny side IN). Continue distillation of the cyclohexene product until the volume in the distillation flask is reduced to about 1 mL. Ask the instructor to assist you in removing the heat source and sand bath for the almost empty flask; use Ove Gloves and/or clamps to avoid burns. |
The NP swab is collected by having a person tip their head back, then a Dacron swab (like a long Q-tip) is gently inserted into one of the nostrils until resistance is met (about 1 to 2 inches in), then rotated several times and withdrawn. This is not painful, but it may tickle a bit and cause the person's eyes to tear. 5. Discuss the rationale for the following interventions in the clinical management of RSV-bronchiolitis: humidified oxygen, oxygen saturation monitoring, nasopharyngeal suctioning and intravenous fluid administration (include the formula for calculating maintenance fluid requirements for a pediatric patient) p. 1400 – 1402 Humidified Oxygen: promote adequate gas exchange & liquefy secretions for ease in clearance; addition of moisture to inspired air Oxygen Saturation Monitoring: detect alterations in oxygenation; infants & children can deteriorate quickly as the disease progresses. Supplemental oxygen need to be adjusted as needed based on their current O2 saturation Nasopharyngeal Suctioning: promote clearance of secretions; improve gas exchange; removal of secretions via bulb syringe or suction catheter; maintains a patent airway p.
The symptoms can cause discomfort. Some of symptoms include nausea, vomiting, feeling cold and warm at the same time. Detoxification will flush out the drug. Prescription drug detox is a process of cleansing the body from the harmful effects by prescribed medication. The detox process is the first step towards effective drug treatment in prescription drug rehabilitation.
