Blood Transfusions

Blood Transfusions. Blood transfusions are sometimes required in healthcare. Based on what you know about blood anatomy discuss why a patient would need a transfusion of PRBC (packed red blood cells), plasma, or platelets. A patient with anemia has a pulse oximetry reading in the high 80’s, would this be an expected finding, explain?
Mike, 29 years old, was admitted to a community hospital three days ago with weakness and hypotension after sustaining a spider bite while hiking in the woods. Mike has a large hematoma on his left arm where he was bite. He has no prior medical history, no drug allergies, and does not take medication. Mike started to experience moderate respiratory distress, and started oozing blood from his IV sites, nose, and catheter. He is mildly jaundice and his skin is cool. His vital signs include a heart rate of 110 beats per minute and regular blood pressure of 92/44, slightly labored respiratory rate of 22 breaths per minute, and a pulse oximetry reading of 91 percent. What would your initial diagnosis be, explain? What diagnostic test would you order and why? What would you expect the diagnostic test to show? What is the treatment option for the diagnosis?
During natural disasters like hurricanes, when the community is living in shelters, why would there be a concern about a tuberculosis outbreak? What circumstances have led to the spread of drug-resistant tuberculosis? Mary, a nurse, skin test was positive for tuberculosis. Does this mean she has tuberculosis? Explain.
Each year many people go to their family physician with a common cold, but think they have the influenza. Based on symptoms how can you tell if you have a common cold or influenza? What are the causes and treatments for Pneumonia? What is the best way to prevent influenza and pneumonia?

Summary of findings

 

*************************************

 

 

 

Instructions:

 

Demonstration of your knowledge of basic laboratory skills, experimental design, and/or data evaluation will be assessed by the submission of an applied final lab project.

 

Based on the outline, and the Lab submitted, the 4 outcomes need to be addressed

Laboratory Assignments

Addresses course outcomes 1-4:

·       recognize and explain how the scientific method is used to solve problems

·       make observations and discriminate between scientific and pseudoscientific explanations

·       weigh evidence and make decisions based on strengths and limitations of scientific knowledge and the scientific method

·       use knowledge of biological principles, the scientific method, and appropriate technologies to ask relevant questions, develop hypotheses, design and conduct experiments, interpret results, and draw conclusions

 

 

 

Experiment 2: Effect of Temperature on Enzyme Activity

Pre-Lab Questions

1. What reaction is being used to study the effect of temperature on enzyme activity in this experiment? Temperature can affect the enzyme catalytic reaction.

 

2. What does an increase in balloon diameter mean with respect to enzyme activity? The activity increases as well

 

 

3. Why is important to know this information before starting Experiment #1? The diameter of the balloon will show the activity of the enzyme based upon temperature.

 

Table 2: Balloon Circumference vs. Temperature
Tube Temperature (°C) Uninflated Balloon Circumference (cm) Final Balloon Circumference (cm) Difference in Balloon Circumference (cm)
1 – (Cold) 1  4 inches  6.5 2.5
2 – (RT)  2.3    6.75 2.75
3 – (Hot)  4    7.25 3.25

 

Insert labeled photos of your initial and final balloons here. Photos must be labeled! Include a note with your name and date on an index card in the pictures.

 

Post-Lab Questions

 

1. What is the enzyme in this experiment? The catalase. What is the substrate? The Hydrogen Peroxide

 

2. What is the independent variable in this experiment? Temperature. What is the dependent variable? Balloon diameter

 

3. How did temperature affect enzyme function? Hot temperature causes high enzyme activity, the cold has less activity, but the room temperature’s activity was slower to react.

 

 

4. Is there a negative control in this experiment? No negative controls. To revise we would use water, therefore nothing would be expected to happen.

“Keystone Species, Shrinking Red Knots, and Biomes”

“Keystone Species, Shrinking Red Knots, and Biomes”.

“Keystone Species, Shrinking Red Knots, and Biomes”

Our focus this week is on ecology.  Ecology is the study of interactions among organisms and between organisms and their physical environments. For your primary post, respond toone of the following three topics. Also, reply to at least one fellow student on any topic.

Topic 1

:  Keystone Species. Watch the video entitled “Some animals are more equal than others…” (1)* Then completely describe the concept of a keystone species, giving specific examples from the video.

Topic 2 [articles]: Shrinking Red Knots. Read two of the following three articles about shrinking Red Knots (2)*, (3)*, (4)*, or research additional information on your own. Then, address the following issues:

  • (a) Explain how the lifecycle of the Red Knot depends on hatchlings emerging at the same time as the insects hatch.
  • (b) What are the long-term ramifications of having a mismatch between the bird hatch and the insect hatch?
  • (c) Of the two articles you read, which of them do you feel was most informative?  Why?

Topic 3 [research]: Biomes. The term “biome” is described in the textbook. For this topic, describe the biome where you grew up (or where you currently live). Identify your location, the biome of the region, and describe the major characteristics of that biome. Add enough detail and commentary from your own experience. If you’re really ambitious, you could consider looking up the EPA “ecoregion,” which will give additional details about your region.
