37
Define objective data.
Anything you observed, such as diaphoresis, lab values, grimacing
38
What is meant by a General Survey?
First impression prior to exploring any systems in detail, Collecting objective data, helps to guide subjective questioning
Looking at physical appearance, body structure, mobility, behaviors, vital signs, etc
39
What measurements and observations are included in the General Survey?
Vital signs may be a measurement included, also included may be the physical appearance (Maybe examining how diaphoretic someone is), looking at body structure and mobility (Do they need assistance, is the circumstance safe), as well as behaviors (are they agitated- which could be a sign a pain)

Open ended questions- Provide the opportunity for more than a one word answer. Allows the client to expand upon the current question asked. (How are you feeling today, are you interested in the cessation of smoking?) May use it in times of attempting to build rapport, or when assessing a problem on a deeper level

50
Who is at greatest risk of developing A pressure injury?
Elderly individuals with thin skin, people who are bedridden, any individual who may experience incontinence (Too much moisture can assist in the breakdown of the skin). Also individuals with impaired sensory perception because they may not feel any pain with the injury.
51
Know the stages of the Pressure Injury Staging system.

64
Understand the structure of the thorax and the lungs.
Thoracic cage consists of the sternum (Top part is called the manubrium), Ribs, Thoracic vertebrae connect the ribs in the back, and the diaphragm which is a large skeletal muscle which aids in chest expansion for breathing
* Lungs- Right lung consists of three lobes, Upper, Middle, and Lower Lung (Right middle lung can only be heard on the anterior portion of the body). The Left lung is composed of two lobes, Upper and lower.
*Breathing- Air enters the lungs through the mouth or nose, travels through the pharynx down the trachea and to the two primary bronchi (Left and Right, Right bronchi being larger and straighter which typically causes problems when it comes to aspiration). Oxygen goes through the primary bronchi, to secondary bronchus and then to tertiary bronchus and into the alveoli where gas exchange can occur

Invasive: ABG (Arterial Blood Gas), Hemoglobin and Hematocrit
69
What are 3 types of vocal fremitus?
* Bronchophony: Increasing in intensity and clarity of spoken sounds when auscultating with the stethoscope (Have the client say “ninety-nine”
* Egophony: Have the client say E-E-E-E, if it sounds like A-A-A-A, lung consolidation is present
* Whispered pectoriloquy: Unusually clear transmission of whispered words indicating lung consolidation (Have the client say ninety-Nine)

Why is circulation different in the fetus?
Fetal circulation compensates for non-functional fetal lungs. The fetus is oxygenated with maternal blood flow through the placenta
Circulating blood bypasses the lungs and liver by flowing in different pathways and through special openings called shunts
At birth, the umbilical cord is clamped (Baby no longer receives nutrients from the placenta). With the first breath of air the lungs start to expand and the ductus arteriosus and the foramen ovale both close
185
What is the purpose of the shunts in the fetal heart?
Shunts are special openings that allow the circulating blood to bypass the lungs and the liver, because it gets oxygen from mother through the placenta.

192
Describe “hyperactive” bowel sounds and what they indicate.
(increased) bowel sounds are louder and more intense than expected because of increased motility or peristalsis of the bowels as with diarrhea. You might hear rushing sounds or tinkling at a frequency of about every few seconds, and greater than 34 per minute.
193
Describe “hypoactive” bowel sounds and what the indicate.
(decreased) bowel sounds are diminished, soft sounds that occur less than 5 per minute and could be related to impaired motility. This can be related to side effects from medication or anesthesia, constipation, or bowel obstruction.
194
If chyme moves more slowly through the intestines would the stool be harder or softer, and why?
The speed at which chyme moves through the intestines dictates how much water is reabsorbed in the Large intestine. If the chyme moves too quickly, less water will be absorbed therefore resulting in softer stool. If chyme moves too slowly, lots of water is reabsorbed, drying it out making it harder
