Please help me this is confusing

Answer: Ok Diastole commences with the closure of the aortic and pulmonary valves. Intraventricular pressure falls but there is very little increase in ventricular volume (isovolumetric relaxation). Once ventricular pressure falls below atrial pressure, the mitral and tricuspid valves open and ventricular filling begins.The first heart sound (S1) is produced by vibrations generated by closure of the mitral (M1) and tricuspid valves (T1). It corresponds to the end of diastole and beginning of ventricular systole and precedes the upstroke of carotid pulsation.

As a pharmacy technician, there are several steps you can take to safely prepare and handle hazardous drugs in the pharmacy. Here are five important steps:

1. Education and Training: Ensure that you have received proper education and training regarding the safe handling of hazardous drugs. Familiarize yourself with the pharmacy's policies and procedures for handling these drugs, including any specific guidelines or protocols.

2. Personal Protective Equipment (PPE): Always wear the appropriate personal protective equipment when handling hazardous drugs. This may include gloves, gowns, masks, and protective eyewear. PPE helps protect you from direct contact with the drugs and prevents the inhalation or absorption of hazardous particles.

3. Proper Storage and Labeling: Follow the pharmacy's guidelines for storing hazardous drugs safely. Ensure that these drugs are stored separately from non-hazardous drugs to prevent cross-contamination. Additionally, make sure that all hazardous drug containers are properly labeled with the appropriate warning labels or symbols.

4. Containment Measures: Use appropriate containment measures to prevent the spread of hazardous drug particles. This includes using designated spill kits, leak-proof containers, and containment bags for waste disposal. Properly seal containers and dispose of hazardous drug waste according to regulations and guidelines.

5. Cleaning and Decontamination: Regularly clean and decontaminate work surfaces, equipment, and tools that come into contact with hazardous drugs. Follow established cleaning protocols and use appropriate disinfectants to minimize the risk of contamination. Dispose of cleaning materials properly after use.

Answer:

Each dose of the drug must contain 47.62 milligrams of it.

Explanation:

Given that the doctor prescribed 3 mg / kg twice daily for 5 days, the child weighs 35 pounds and the medication is available as 50 mg / mL, to determine how many mL should be administered to the child for each dose, the following should be done calculation:

1 pound = 0.453592 kilos

35 pounds = 0.453592 x 35 = 15.8757 kilos

15.8757 x 3 = 47.6271

Thus, each dose of the drug must contain 47.62 milligrams of it.

1 kg = 2.205 pound

Since the child weigh 35 pounds, hence:

35 pounds = 35 pounds * 1 kg per 2.205 pound = 15.88 kg

The doctor prescribed 3 mg/kg twice daily for 5 days. For each dose, the mg needed is:

mg = 3 mg/kg * 15.88 kg = 47.64 mg

Since the medication is available as 50 mg/mL, hence:

ml = 47.64 ml / 50 mg/mL = 0.95 ml

0.95 ml should be administered to the child for each dose
