Clinical Case Study and Med Calculation, Liquids for Injection Aiden Avery, age 54, has a history of Type Il diabetes for 5 years. He is seen in an urgent care clinic for complaints of shortness of breath, nonproductive cough, wheezing, and dyspnea for 1 week. Mr. A is admitted to the hospital to rule out pneumonia. At present, Mr. A has no intravenous access. Medication orders: NPH insulin 10 units subcutaneous daily Regular insulin 15 units subcutaneous daily • Sliding scale insulin: ac (before meals) and at night. For blood glucose greater than 200, administer regular insulin subcutaneously, according to formula: BG-100/40= number of units of regular insulin ● ● ● ● ● ● methylprednisolone 80 mg IVP every 8 hours ticarcillin 750 mg IM now ceftazidime 400 mg IM now morphine 4 mg IM now Calculate the doses (do not round, unless directed): 1. methylprednisolone.

The giucose tolerance test is prescribed under which of the following patient scenarios? Fasting blood sugar greater than 7.8 mmol/L and patient presents with the signs and symptoms of hyperglycemia. Fasting blood sugar greater than 7.8 mmol/L O Fasting blood sugar increased and patient asymptomatic. Fasting blood sugar less than 7.8 mmol/L and patient presents with the signs and symptoms of hyperglycemia
In a placebo-controlled study, 10 healthy subjects were given oral triazolam 0.5 mg before and after rifampicin 600 mg daily for 5 days. Rifampicin reduced the triazolam AUC by 95% and decreased its maximum plasma levels by 88%, when compared with placebo. The elimination half-life was reduced from 2.8 hours to 1.3 hours. Pharmacodynamic tests (drowsiness, sway, Maddox wing, etc.) showed that rifampicin abolished the effects of triazolam.a) Why is the AUC of triazolam reduced in the presence of rifampicin? b) Given the above scenario, if you were to accommodate this situation by dosage adjustment strategies, in the presence rifampicin what dose of triazolam would you have recommended, keeping dosage interval the same as when there was no rifampicin? answer part b

Compared to the above urine test, a blood test for glucose is more accurate in avoiding both false positive and false negative results in identifying diabetic patients. If a blood test for glucose correctly identifies 90% of diabetic patients, but gives false-positive results for 12% of non-diabetic patients, then: the blood glucose test has improved sensitivity, but reduced specificity (compared to the urine test) the blood glucose test has improved neither sensitivity nor specificity (compared to the urine test) the blood glucose test has reduced both sensitivity and specificity (compared to the urine test) the blood glucose test has improved both sensitivity and specificity (compared to the urine test) the blood glucose test has improved specificity, but reduced sensitivity (compared to the urine test)
