Vitals
Measurement that indicate the state of a patient's essential body functions.
What is a vital sign?
Single-celled organisms that do not rely on a host
What are bacteria?
The use of practices and procedures to prevent contamination from pathogens
What is aseptic technique?
A proposed explanation based on some evidence and used as a starting point to investigate further.
What is a hypothesis?
What does this equation calculate?
beats x 4 = BPM
Pulse
The four vital signs we have studied
What are blood pressure, heart rate, temperature, and respiratory rate?
Tiny infectious agents that can only multiply when they are inside a host. Not technically a living organism
What is a virus?
The student put the bacteria plate on the table without a lid. Find the error.
The student should not leave bacteria plates uncovered.
Variable is changed by the person conducting the experiment.
What is independent variable?
Control: 0 cm
Ampicillin: 1.3 cm
Tetracycline: 2.3 cm
Erythromycin: 1.4 cm
Based on these measurements, which antibiotic is most effective?
What is tetracycline?
What happens to pulse after exercise?
Pulse increases
Organisms that reproduce quickly in moist, humid environments. Often live on dead/decaying material
What is fungi?
An antibiotic that kills bacteria is considered to be...
What is bactericidal?
Variable is the measurable effect or response. It is observed or measured.
What is dependent variable?
You are looking at patient test results.
The positive control is purple
The negative control is blue
The patient sample is blue
Does the patient have the disease? Why/why not?
No because the patient sample results do not match the positive control
Result of relaxation techniques on respiratory rate
Respiratory rate decrease
A microscopic organism such as a bacterium, virus, or fungus.
What is a microorganism?
An antibiotic that stops bacteria from growing is called...
What is bacteriostatic?
Research question

What is experimental design?
Gram negative bacteria we grew in class.
What is E. coli?
Hypothesis: Jumping jacks (jj) increase pulse.
Trial 1
Pulse after jj: 89
Trial 2
Pulse after jj: 88
Trial 3
Pulse after jj: 91
WHAT CRITICAL PART IS MISSING?
Control: the resting pulse
Find the error and explain why it is wrong:
A person went to the doctor and was diagnosed with the flu. The doctor prescribed antibiotics. The patient felt better in a few days.
Antibiotics cannot treat the flu because the flu is viral. Antibiotics only work for bacterial infections.
The person felt better a few days later because the virus ran its course and NOT because the antibiotics worked.
Control: 0 cm
Ampicillin: 1.3 cm
Tetracycline: 2.3 cm
Erythromycin: 1.4 cm
What are these measurements called?
What is the zone of inhibition?
Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. Height of the tree is measured once a week. What is the IV, DV, and control?
IV: humidity levels
DV: tree height
Control: tree in normal conditions
How would we know which antibiotic had been the most effective in our bacteria lab?
The largest zone of inhibition would have been the most effective antibiotic
