Answer: N-95 respirator must be worn.
Patients with possible TB infection are placed in Airborne Precautions. Anyone who enters the room of a patient in Airborne Precautions should wear an N-95 respirator mask. Always remember to wear an N-95 respirator mask when entering an Airborne Precautions room. Only approved respirator masks can be worn.
Explanation:
Gastric, Testing the pH of a stomach aspirate to a value of 5.5 is the first-line diagnostic to assure correct nasogastric tube insertion and reduce the danger of potentially fatal aspiration.
Adult patients who had bronchoscopy or gastroscopy and had two (one fresh and one frozen) bronchial and esophageal samples or two bronchial and salivary samples each were included in this prospective observational study.
Kappa (k) statistics were used to determine the level of observer agreement for the pH of fresh and frozen samples. To distinguish between gastric and non-gastric aspirates, the sensitivities and specificities at pH 5.5 and the area under the receiver operating characteristics (ROC) curve at various pH cut-offs were computed.97 individuals underwent a gastroscopy, and 106 underwent a bronchoscopy. In 57/92 (62%) of the paired fresh and frozen stomach samples, there was total agreement between the observers (k=0.496, 95% CI 0.364 to 0.627).
The specificity of a pH 5.5 was 79% (95% CI 74 to 84), while the sensitivity of a pH 5.5 to accurately identify stomach samples was 68% (95% CI 57 to 77). Regardless of whether patients were using antacids or not, the overall accuracy to correctly categorize samples was between 76% and 77%. At various pH cut-offs, the ROC curve's area under the curve was 0.74.

Answer:
The thyroid gland absorbs almost all of the iodine in the body. When radioactive iodine (RAI), also known as I-131, is given to the body as a liquid or capsule, it becomes concentrated in thyroid cells. Radiation can kill the thyroid gland and any other thyroid cells or tissues (including cancer cells) that absorb iodine, without damaging any other organs.
Explanation:
The thyroid gland is an organ that belongs to the endocrine system and its function is to synthesize hormones that are responsible for controlling the body's metabolism, this gland has an important characteristic and that is that the hormones it produces have a unique chemical composition due to They are the only hormones that contain iodine in their structure, this in turn is essential for its functioning because the body does not synthesize it and it must be consumed in the diet. When a small dose of the radiopharmaceutical iodine 131 (Sodium Iodide 131I) is consumed, it is absorbed into the bloodstream and concentrated by the thyroid gland, where it begins to destroy cancer cells in the gland. 131I quickly attaches itself to thyroid cells to destroy them, but continues to emit radioactivity for a long time: it takes 8 days to halve. The beta radiation particles of 131I, which we call radioiodine or radioactive iodine, have a range of 2mm and act for a long time in a constant way. Fortunately, the body's metabolism quickly expels iodine through the urine, so that in one day the amount of iodine has decreased considerably.
