where should you position your hand to give abdominal thrusts for a conscious choking victim?
For a conscious choking victim, abdominal thrusts are performed to dislodge the foreign object obstructing the airway.
The hand placement for abdominal thrusts involves standing behind the victim and placing the thumb side of the fist in the midline, just above the navel, and below the ribcage. The other hand is placed over the fist. The rescuer then pulls the fist sharply inwards and upwards towards the chest to generate enough pressure to force the foreign object out.
It is essential to perform abdominal thrusts carefully and in a controlled manner to avoid causing injury to the victim. The thrusts should be repeated until the foreign object is expelled, or the victim becomes unresponsive.
If the victim becomes unresponsive, CPR should be initiated immediately.

Answer:
Exposure to droplets emitted by the cough of an infected person
Explanation:
Pulmonary tuberculosis is produced by the bacterium Mycobacterium tuberculosis. It is a contagious disease that can be transmitted between individuals by the inhalation of airborne particles released by the cough of individuals with tuberculosis.

A physician ordered erythromycin for a child who weighs 45lb and is 3 feet tall. How many mg should be delivered to the child per dose based on the adult of 250mg qid
Orders written "mg/kg/d," which is perplexing, need further explanation from the physician because doses are sometimes expressed as mg/kg/day or mg/kg/dose.
A 37-pound, 77-cm-tall youngster is given an erythromycin prescription by a doctor. 250 mg qid is the typical adult dosage. The calculator expresses the dose in millilitres and milligrammes once you enter your patient's weight and choose the liquid's strength. A kid is 35" tall and weighs 55 pounds. The doctor prescribes ampicillin for the kid on the spot. 500 mg qid is the typical adult dosage. Medicine dosage varies depending on the drug and the patient. Body weight = 3 lbs 7 oz (3 X 454 + 7 X 28.35 = 1560.45) Each divided dose equals 15.6 mg/2=7.8 mg.

when emergency services are needed, an_______ helps to coordinate the urgent response
Fill in the blank. When auscultating the blood pressure in a patient's upper extremity, you should place the diaphragm (head) of the stethoscope over the ______ artery.
When auscultating the blood pressure in a patient's upper extremity, you should place the diaphragm (head) of the stethoscope over the brachial artery.
Brachial Artery:
The brachial artery is a major blood vessel located in the upper arm.
It is commonly used for blood pressure measurements because it is easily accessible and provides a reliable representation of systemic arterial pressure.
Proper Placement of the Stethoscope:
To locate the brachial artery, palpate the area on the inside of the upper arm, just below the shoulder and above the elbow crease. The brachial artery can often be felt as a pulsation beneath the skin. Once identified the brachial artery, place the diaphragm (head) of the stethoscope directly over the artery at this location.Auscultating the Blood Pressure:
With the stethoscope in place, inflate the blood pressure cuff around the patient's upper arm, ensuring it is snug but not too tight. Begin to slowly deflate the cuff while listening with the stethoscope. The first sound heard through the stethoscope is known as the systolic blood pressure, and the point where the sound disappears is the diastolic blood pressure.Thus, to auscultate the blood pressure in the patient's upper extremity, the diaphragm of the stethoscope should be placed over the Brachial artery.
