Why is it important to scrub the "hub" or portal of entry to the patient before connecting anything to them? For example, why do we scrub the port before we connect IV tubing with fluids?
Maintaining a clean environment and preventing infections in patients is a priority in nursing. Taking the time to scrub the hub for 30 seconds before connecting IV tubing ensures that their are no germs that can cause infection that will be sent directly into the patients bloodstream. When germs enter the patient and cause infection, the vessel that contains the infection shrinks and grows scar tissue. In some cases, like dialysis, we lose this access for the patient after an infection. It is important to maintain clean technique in the hospital to keep our patients trending in the direction of recovery instead of in the direction of infection/sepsis.
What are the three layers of the skin? (Not the purpose of each layer because that would be physiology)
Your skin is made up of 3 layers. The outermost layer of skin, this is the part you can physically see, is the epidermis. The epidermis contains melanocytes which produce the pigment of your skin. The layer below is the dermis. This layer contains sweat glands, connective tissue, and hair follicles. The deepest layer of the skin is called the subcutaneous layer. This layer is made up of fat and connective tissue.

What are the different learning types and why do people have different learning styles and ways of understanding concepts?
There are many reasons that people learn and retain information differently. Some people are visual learners meaning they may require a form of teaching that includes lots of visual examples. These people may learn better with charts or graphs and pictures of the concepts. There are tactile learners who learn best when doing the concept they are trying to master. These people are better in hands on situations and feel more confident in their skills after being able to practice them in real life situations. There are auditory learners who learn best hearing things several times. These people may record lectures or presentations to fully understand the concepts. Some people learn best individually, while others learn better in a group. Learning styles may vary because of a person's past experiences. Some people may have grown up with siblings and were used to sharing and working with others. Other people may have been only children and worked through problems on their own. Some people may be a different type of learner because they have a physical impairment. For example, someone with visual disturbances may be more of an auditory learner and prefer to learn alone while someone with poor organizational skills or handwriting may prefer hands on or tactile learning.
