The popliteal pulse point is found on the anterior surface of the elbow. a. True b. False

loris [4]

Answer:

The correct answer choice for the question: The popliteal pulse point is found on the anterior surface of the elbow, would be, A: true.

Explanation:

The popliteal pulse is the passage point of the brachial artery and it is in fact always found on the anterior surface of the elbow, medial to the tendons of the biceps. This major artery, the brachial artery, is the main vessel for the upper arms and it comes out of the axillary artery. As it tranverses down the upper arms, it reaches the cubital fossa of the elbow, where it divides into the radial and the ulnar arteries. When measuring blood pressure, it is usually this artery that is sought out and its sounds can be heard with a sthetoscope, and when using a sphygmomanometer, or blood presure cuff.

A nurse is teaching about a new prescription for infliximab to a client who has rheumatoid arthritis. Which of the following inf

Phoenix [80]

Answer: Opcion A. "You will receive a Mantoux test before the initial medication dose"

Explanation: The INFLIXIMAB is one of the medications used for treating Rheumatoid arthritis, among other inflammatory diseases as psoriasic arthritis, ankylosing spondylitis, Crohn's disease. It is used when the regular treatment has not worked. It helps to reduce pain and joint inflammation.

The mechanism of action of the INFLIXIMAB is to reduce a substance called TNFα (Tumor Necrosis Factor α) responsible for the inflammatory response that helps the body against an antigen. Because this medication reduces this body defense, it is important for the health providers to know in advance if there is a condition or disease in the immune system, cancer, or something that per se, could predispose to infections.

The Mantoux test is a tuberculin skin test that is used to know if a person has an infection with Mycobacterium tuberculosis, the bacteria responsible of causing Tuberculosis. In the test, a tuberculin protein called PPD is used to be injected into the skin, specifically in the forearm. If the person is infected with the bacteria, it is expected that between 48 and 72 hours, the health professional would see an induration in the site of injection.

If someone has a positive tuberculin test, then it would not be possible to administer INFLIXIMAB.

Opcion B. Incorrect. There is no description of diarrhea as an adverse event for using this medication. The adverse effects could be headache, stomach ache, cough or skin allergy. Also, for the suppression of part of the immune system, it is recommended to be aware of symptoms of infection as fever, sweats, muscle pain.

Opcion C. Incorrect. The usual dose of INFLIXIMAB in the treatment of Rheumatoid Arthritis for adults is, an inicial dose, then a second dose 2 weeks later; then, a third dose 4 weeks later, and finally one dose every 8 weeks.

Opcion D. Incorrect. The intranasal influenza vaccine is a "live attenuated" vaccine. If it is administered in a person using INFLIXIMAB, he/she could develop a severe infection by Influenza.

The pancreas releases alkaline, enzyme-rich pancreatic juice into the ____________ of the small intestine. What is the function

grin007 [14]

Answer:

The correct answer is the duodenum.

Explanation:

Pancreatic juice is an alkaline fluid which contains important enzymes for the digestion of proteins, carbohydrates and fats.

Pancreatic juice is secreted by the pancreas when food enters the stomach which is released into the "duodenum" of the small intestine. The pancreatic juice enters duodenum through a pancreatic duct which joins with the bile duct coming from the liver and form "ampulla of Vater" in the duodenum.

Pancreatic juice helps in digestion of carbohydrates, proteins and fats as it contains pro-enzymes and enzymes like trypsinogen, chymotrypsinogen, lipase and many more. It also makes the acidic stomach solution alkaline due to the presence of HCO₃.

Thus, the duodenum is the correct answer.

Explain how the epithelium in each of the following regions of the respiratory tract is adapted so its structure follows its fun

vovangra [49]

Explanation:

a. Nasal cavity: the epithelium in this zone is meant to provide a physical barrier to the invasion of microorganism or particles, it also secretes and remove mucus and foreign particles, these epithelial cells are also involved in the igE producing process (perpetuating allergic responses. The nose is the first barrier to the air that enters our body, that's why the epithelial cells in this zone focus in filtering foreign particles.

b. Bronchiole: epithelium is ciliated and no ciliated, it becomes cuboidal in smaller passages as it continues to branch. The no ciliated cells, also known as club cells are the ones that produce surfactant. Since bronchioles are passages to direct the air to the alveoles epithelial cells in this zone have adapted to go from larger branches to smaller ones to reach the alveoli.

c. Alveolus: it's composed of two types of cells, type one, that constitute the air-blood barrier and type two, cells that produce surfactant to reduce surface tension to keep the alveolus shape when breathing. Since alveoli's function is to allows oxygen/carbon dioxide to move between bloodstream the epithelial cells in this organ evolved to cover this job.
