A 27-year-old patient with a history of substance abuse is found unresponsive by emergency medical services (EMS) after being called by the patient’s roommate. The roommate states that he does not know how long the patient had been lying there. Patient received naloxone in the field and has become responsive. He complains of burning pain over his left hip and forearm. Evaluation in the ED revealed a large amount of necrotic tissue over the greater trochanter as well as the forearm. EKG demonstrated prolonged PR interval and peaked T waves. Serum potassium level 6.9 mEq/L.

Post an explanation of the disease highlighted in the scenario you were provided. Include the following in your explanation:

  • The role genetics plays in the disease.
  • Why the patient is presenting with the specific symptoms described.
  • The physiologic response to the stimulus presented in the scenario and why you think this response occurred.
  • The cells that are involved in this process.
  • How another characteristic (e.g., gender, genetics) would change your response

D.R. is a 27-year-old man, who presents to the nurse practitioner at the Family Care Clinic complaining of increasing SOB, wheezing, fatigue, cough, stuffy nose, watery eyes, and postnasal drainage—all of which began four days ago. Three days ago, he began monitoring his peak flow rates several times a day. His peak flow rates have ranged from 65-70% of his regular baseline with nighttime symptoms for 3 nights on the last week and often have been at the lower limit of that range in the morning. Three days ago, he also began to self-treat with frequent albuterol nebulizer therapy. He reports that usually his albuterol inhaler provides him with relief from his asthma symptoms, but this is no longer enough treatment for this asthmatic episode.

According to the case study information, how would you classify the severity of D.R. asthma attack?
Name the most common triggers for asthma in any given patients and specify in your answer which ones you consider applied to D.R. on the case study.
Based on your knowledge and your research, please explain the factors that might be the etiology of D.R. being an asthmatic patient.

A pizza shop claims its average home delivery time is 27 minutes. A sample of 30 deliveries had a sample average of 30.7 minutes. Assume the population standard deviation for the​ shop's deliveries is 7.1 minutes. Complete parts a and b below. a. Is there support for the​ shop's claim using the criteria that the sample average of 30.7 minutes falls within the symmetrical interval that includes​ 95% of the sample means if the true population mean is 27 ​minutes? Select the correct choice below and fill in the answer box within your choice. ​(Type an integer or decimal rounded to four decimal places as​ needed.) A. The probability Upper P left parenthesis x overbar greater than or equals 30.7 right parenthesisequals nothing. This indicates that the sample average of 30.7 minutes falls within the​ 95% symmetrical​ interval, supporting the​ shop's claim. B. The probability Upper P left parenthesis x overbar greater than or equals 30.7 right parenthesisequals 0.0022. This indicates that the sample average of 30.7 minutes falls outside the​ 95% symmetrical​ interval, contradicting the​ shop's claim. Your answer is not correct. b. Identify the symmetrical interval that includes​ 95% of the sample means if the true population mean is 27 minutes.
