- Question 1: Write a 1-2 page analysis stating your decision regarding whether the nurse was liable for the death of the patient in the scenario below. IT’S YOUR GAVEL… CHANCE OF SURVIVAL DIMINISHED On the afternoon of May 20, the patient, Mr. Ard, began feeling nauseated. He was in pain and had shortness of breath. Although his wife rang the call bell several times, it was not until sometime later that evening that someone responded and gave Ard medication for the nausea. The nausea continued to worsen. Mrs. Ard then noticed that her husband was having difficulty breathing. He was reeling from side to side in bed. Believing that her husband was dying, she continued to call for help. She estimated that she rang the call bell for 1.25 hours before anyone responded. A code was eventually called. Unfortunately, Mr. Ard did not survive the code. There was no documentation in the medical records for May 20, between 5:30 PM and 6:45 PM, that would indicate that any nurse or physician…Question 1: Suppose you have given 5 tablets weighing 449mg, 450mg, 448mg, 451mg and 453mg, respectively. Calculate 300 mg equivalent sample weight for assay. The product claim is 500 mg Vitamin C is present in each tablet. Question 2: Volume of the standard sodium edetate is 12.6 mL (calculated after the assay of Zinc Sulfate Syrup). Determine the % of potency of the drug considering the claimed dose is 11.5Question:- Among this group the investigators measured serum cholesterol levels. The men had the following distribution across serum cholesterol: 100 had serum cholesterol levels of less than 200 mg/dL, 600 had levels of 200-270 mg/dL and 300 had levels greater than 270 mg/dL. There were 5 new cases of coronary heart disease among males with serum cholesterol 200-270 mg/dL and 5 among those with levels greater than 270 mg/dL.What was the relative risk of coronary heart disease comparing males with serum cholesterol 200-270mg/dL to those with levels >270 mg/dL? Among the civil service employees in the previous question, what was the relative risk of coronary heart disease comparing males with serum cholesterol >270mg/dL to males with serum cholesterol 200-270 mg/dL?.
