- Nizatidine injection (25 mg/mL) is supplied in 4-mL vials. The prescription states that for continuous infusion 'dilute 300 mg in 150 mL and give at a rate of 10 mg/hour'. If this procedure is adopted, calculate: (a) how many vials of nizatidine injection will be required (b) the flow rate (in mg/hour). NOTE: PLEASE GIVE THE ANSWER WITHIN 2 HOURS THANK YOU200 mg of drug is given IV, plasma drug concentration is 70 mg/L. Calculate the Vd? Where most of the drug is distributed to? Note: Volume of Distribution (L) = Amount of drug in the body (mg) / Plasma concentration of drug (mg/L). O a. Vd=14000 L, drug is mostly outside of plasma, distributed to tissues O b. Vd=2.8 L, drug is mostly outside of plasma, distributed to tissues OC. Vd =0.35 L, drug is mostly in plasma Od. Vd=2.8 L, drug is mostly in plasma O e. Vd =0.35 L, drug is mostly outside of plasma, distributed to tissuesThe order is for 980 mL of D2.5W (2.5% dextrose in water) to infuse intravenously over a period of 8 hours (the drop factor is 20 gtt per mL).

- Newer clinical guidelines suggest using a cut-point value of 120 mmHg for systolic blood pressure to identify a person as being hypertensive. However, some clinicians and researchers have suggested increasing the cut-point value for systolic blood pressure to 130 mmHg to identify hypertension (i.e., those with systolic blood pressure of 130 mmHg and above would be positive for hypertension). If the cut-point value for identifying a person as hypertensive was increased from 120 mmHg to 130 mmHg, which of the following may occur? A. The sensitivity of the new cut-point value would increase. B. The specificity of the new cut-point value would increase. C. Both the sensitivity and specificity of the new cut-point value would increase. D. There would be no change to the sensitivity or specificity of the new cut-point value.1) Please answer the following regarding Cardiovascular Drugs. A) What are the difference between the hypertensive drugs and list the drug corresponding to each category:1. Beta Blockers, 2.Calcium Channel Blockers, 3.Ace Inhibitor,4. Angiotensin II Blockers, 5.
