The correct compressions-to-ventilations ratio during a 1-person rescue on an adult is 30 compressions to 2 breaths (30/2).
<h3>What is the ratio of compression to ventilation for a 1 person rescue?</h3>
- Prior to the American Heart Association changing the criteria owing to studies, compression depth and rate for people of different ages were not the same.
- According to research, one or two-person CPR requires the same or a minor adjustment.
- The compression ratio for a single rescuer conducting CPR on an adult, child, newborn, or neonate is 30/2. The changes are minute, but they necessitate prompt response.
- Two breaths are administered for every 30 compressions. However, healthcare personnel must use a pocket mask or breathing equipment.
- The AHA does not need laypeople to take breaths, but it does require that chest compressions at 100 to 120 compressions per minute begin immediately.

Answer: No, animal shouldn't be exposed to painful or harmful procedures in an experiment. Instead animal care should be put in place
Explanation: Animal care can be defined as the policies, standards, organizational structure, procedure, staffing, facilities, and necessary practices that are put into place by any organization or institution to achieve the humane care and good use of animals in the laboratory without exposing them to harmful nor painful procedures.
Examples:
(1) By performing diagnostic tests and x-rays before carrying out any research .
2. By preparing animals and the necessary instruments for surgery.
3. Prompt medications administration, vaccines, and treatments.
4. Availability of first aid treatment or general nursing care.
5.Frequent observation and report on the condition and behavior of animals.
Answer:a. This study involved comparison of two populations. What were the populations?
1) Pregnant women who took the drug.
2)Pregnant women who didn't take the drug.
b. Do you suppose the data were obtained in a survey or experiment?
- Survey
C.Provide a descriptive statistic that could be used to estimate the number of women out of 1000 in this population who have tissue abnormalities.
-out of 1,000 women developed tissue abnormalities
63/3980=.0158
15.8%
D. remember that women whose mothers took the drug were twice as likely to develop tissue abnormalities.)
___ out of 1,000 women developed tissue abnormalities
15.8/2
7.9
e. Medical sudies often use a relatively large sample (in this case 3980). Why?
medical studies often use a relatively large sample (in this case, 3980) because disease occurrences can be rare and difficult to observe when only isolated populations are considered.
