A Physician orders amiodarone 1 mg/min for six hours, then 0.5 mg/min thereafter. The patient's weight is 156 lbs. The concentration of the IV bag comes as 1.8 mg per ml. Calculate the infusion rate in mL/hr.
[1 mg/ 1 min] 60min= 60mg/hr. 60 mg/hr [1 mL/ 1.8 mg] = 33.33 mL/hr 0.5 mg/min [60 min/ 1 hr] = 30 mg/hr 30 mg/hr [1 mL/1.8 mg] = 16.67 mL/hr Infusion rates: 33.33 mL/hr for 6 hours, then 16.67 mL/hr

Glucagon-like peptide-1 receptor agonists Sulfonylureas work in beta cells in the pancreas that are still functioning to enhance insulin secretion. Alpha-Glucosidase Inhibitors stop -glucosidase enzymes in the small intestine and delay digestion and absorption of starch and disaccharides which lowers the levels of glucose after meals. DPP4 blocks the degradation ofGLP-1, GIP, and a variety of other peptides, including brain natriuretic peptide. Glucagon-like peptide-1 receptor agonists work in various organs of the body. Glucagon-like peptide-1 receptor agonists enhance glucose homeostasis through: (i) stimulation of insulin secretion; (ii) inhibition of glucagon secretion; (iii) direct and indirect suppression of endogenous glucose production; (iv) suppression of appetite; (v) enhanced insulin sensitivity secondary to weight loss; (vi) delayed gastric emptying, resulting in decreased postprandial hyperglycaemia. Thiazolidinediones are the only true insulin-sensitising agents, exerting their effects in skeletal and cardiac muscle, liver, and adipose tissue. It ameliorates insulin resistance, decreases visceral fat. Biguanides work in liver, muscle, adipose tissue via activation of AMP-activated protein kinase (AMPK) reduce hepatic glucose production. SGLT2 inhibitors work in the kidneys to inhibit sodium-glucose transport proteins to reabsorb glucose into the blood from muscle cells; overall this helps to improve insulin release from the beta cells of the pancreas.

The rate that an outcome will occur given a particular exposure, compared to the rate of the outcome occurring in the absence of that exposure is definition of which of the following?
RR = rate of an outcome occurring in an exposed group (treatment group/intervention group) divided by the rate of an outcome occurring in an unexposed group (control group) Ex: Relative Risk = Rate of UTI in patients taking drug XYZ / rate of UTI in patients not on drug XYZ

It is recommended to monitor complete blood count in patients on chronic metformin because of what reason?
Metformin may impair the absorption of vitamin B12, especially in those with inadequate vitamin b12 or calcium intake/absorption. Vitamin b12 deficiency can be treated with discontinuation of therapy or supplementation. Vitamin b12 serum concentrations should be monitored periodically with long-term therapy.
