It has closely packed cells in multiple layers that are continuously being shed. Keratin covers the skin, which creates a salty, acidic environment inhospitable to microbes. It also contains antimicrobial proteins and lysozymes that inhibit microorganisms and help to destroy them. Your Answer: Explain how the skin’s physical barrier makes it inhospitable to microorganisms.

He presents to the emergency room with an anaphylactic reaction. (1) What symptoms might he present with? (2) Does the quantity of exposure mean he will have a more severe reaction? (3) What is the initial immediate treatment? (4) What are 2 things people with anaphylaxis should always carry? Your Answer: 1. tachycardia, vomiting, dyspnea, and cardiac arrest 2. no the quantity of exposure doesn't mean he will have a more severe reaction. 3. epinephrine 4. id of allergy and EpiPen (1) Any of the following reactions are accepted. Grade I: erythema and urticaria, with or without angioedema. Grade II: hypotension, tachycardia, dyspnea, and GI manifestations, like nausea, vomiting, diarrhea, and abdominal cramping from mucosal edema. Grade III: bronchospasm, cardiac dysrhythmias, and cardiac collapse. Grade IV: cardiac arrest (2) No (3) Epinephrine (4) identification about allergy, EpiPen false, antibiotics can’t penetrate the abscess wall, so incision and drainage are necessary.

Short answer: Not yet graded / 5 pts Question 18 Question 19 Not yet graded / 10 pts Short answer A 40-year-old man presents with cough and shortness of breath. After an H&P and chest films, it is determined he has pneumocystis carinii pneumonia (PCP). The provider does an HIV test, which is positive. Upon further testing, the man’s CD4+ cell count is 100 cells/µL and his viral load is 250,000 copies/mL. (1) Why did the provider do an HIV test after the man was diagnosed with PCP? (2) What classification does this man fall into based on his CD4+ count and symptomatology, and why? Your Answer: The man's CD4+ cell count is below 200 cells which will make him more decidable to opportunistic infection that produces infection without impaired immune functions. The man falls into the last phase since his CD4+ is below that 200 mark. (1) Opportunistic infections are those common organisms that do not produce infection without impaired immune function. (2) The last phase, or AIDS illness, occurs when the CD4+ cell count falls to less than 200 cells/µL or exhibits an AIDS- defining illness. The risk of opportunistic infections and death increases significantly when the CD4+ cell count falls below 200 cells/µL. fibroblasts Your Answer: The cells primarily responsible for the tissue building that occurs during the proliferative phase of wound healing are known as what?
