The signs and symptoms of changes in respiratory rate during the refractory stage include rapid or shallow breathing, difficulty in catching one's breath, an increased or decreased respiratory rate, cyanosis (bluish discoloration of the skin), and altered levels of consciousness.
During the refractory stage, which is the final stage of respiratory failure, the body's ability to maintain a normal respiratory rate becomes severely compromised. As a result, the following signs and symptoms may occur:
1. Rapid, shallow breathing: The respiratory rate may increase, but the depth of each breath may become shallower.
2. Difficulty breathing: Patients may experience shortness of breath or a feeling of suffocation.
3. Cyanosis: A bluish discoloration of the skin, lips, or nails may occur due to decreased oxygen levels in the blood.
4. Confusion or disorientation: Lack of oxygen can affect the brain and cause confusion, disorientation, or even loss of consciousness.
5. Fatigue: Patients may become extremely tired due to the increased effort required to breathe.
6. Chest pain: In some cases, patients may experience chest pain or discomfort due to the strain on the respiratory muscles.

Scenario One Ethan walks through his house and steps his left foot on a game piece lying on the floor. The game piece is sharp. He quickly lifts his foot and shouts, "Ouch!" Ethan grabs the bottom of his foot with both hands and hops up and down on his right foot. Input the PNS receives Output the CNS sends out CA
Answer:
PNS receives information from sensory neurons whereas the CNS sends out to the muscles through motor neurons.
Explanation:
The Peripheral nervous system receives the message from sensory neurons that are present on the foot. After that, Peripheral nervous system sends this sensory information about the body to the central nervous system such as brain and spinal cord. After receiving information from Peripheral nervous system, the central nervous system order the muscles of the leg to lift his leg far away from the sharp game piece. The orders taken by the motor neurons which is responsible for carrying instructions from central nervous system to the muscles for action against stimulus.

a child has a right femur fracture caused by a motor vehicle crash and is placed in skin traction temporarily until surgery can be performed. during assessment, the nurse notes that the dorsalis pedis pulse is absent on the right foot. which action would the nurse take?
during assessment, the nurse notes that the dorsalis pedis pulse is absent on the right foot, so the nurse would : Notify the health care provider (HCP) (Option 4).
The absence of the dorsalis pedis pulse in a child with a right femur fracture is a concerning finding as it suggests compromised blood flow to the foot. This may indicate vascular compromise or arterial injury. It is crucial to notify the health care provider immediately to ensure prompt evaluation and intervention to restore adequate blood flow to the foot.
While administering an analgesic may be necessary to manage the child's pain, it does not address the underlying issue of compromised blood flow and should not be the nurse's primary action in this situation. Releasing the skin traction or applying ice to the extremity would not address the potential vascular issue and could potentially worsen the condition. Promptly notifying the health care provider allows for appropriate assessment and intervention to prevent further complications.

Part 1
Dr. Johnson has just seen 56-year-old Patrick Ghastin. Mr. Ghastin has been experiencing severe headaches and neck pain over the past three months. Dr. Johnson, a doctor of osteopathic medicine, suspects that Mr. Ghastin might have a misalignment of his spinal column, which could be causing the headaches and neck pain. Dr. Johnson has informed Mr. Ghastin that he would like to refer him to a chiropractor. At the end of the visit, Dr. Johnson says goodbye to Mr. Ghastin and informs him that his assistant, Priysha, will be in to go over his paperwork before he leaves.
As Priysha begins to review the doctor's orders with Mr. Ghastin, he interjects, "What is a chiropractor, anyway? I've heard that they aren't real doctors." With a chuckle, Priysha replies, "I HAVE NO IDEA WHAT A CHIROPRACTOR ACTUALLY DOES; YOUR GUESS IS AS GOOD AS MINE."
Mr. Ghastin is less than impressed with Priysha's response. "Well, I don't plan on going to see any chiropractor. I'll just try taking more of my pain medications. That will probably help." Priysha replies, "IT IS UP TO YOU, MR. GHASTIN. JUST BE SURE TO LET US KNOW HOW YOU ARE FEELING."Review the first boldface statement. Was Priysha's response appropriate for explaining the type of practice that is typically provided by a chiropractor?

Case Study 3 – Consent
A 14-year-old youth suffering depression does not want to discuss his problems with his parents. He seeks help from a community health centre. On his first visit he is provided with counselling and asked to return for a second visit where the possibility of medication will be discussed. He is reassured that his parents do not have to be involved if he does not want them to be. Researchers from the centre are looking for people to take part in a study that will find out if a new investigational drug can help in the treatment of depression. They invite the fourteen-year-old to participate in the randomised controlled trial. The researchers say that parental consent is not needed for the 14-year-old to access treatment so they do not need to obtain parental consent for him to participate in the research.

In performing a ten-fold dilution series from a sample containing 10,000 bacteria per milliliter, the third tube in the dilution series will have how many cells per milliliter?
Explanation:
Serial dilutions are used to calculate the concentration of microorganisms. As it would usually be impossible to actually count the number of microorganisms in a sample, the sample is diluted and plated to get a reasonable number of colonies to count. Since each colony on an agar plate theoretically grew from a single microorganism, the number of colonies or Colony Forming Units is representative of the number of viable microorganisms. Since the dilution factor is known, the number of microorganisms per ml in the original sample can be calculated.
A dilution problem such as the one shown above is relatively easy to solve if taken step by step. Follow the steps below.
First determine which is the countable plate.
Count the number of colonies on each plate. If there are too many colonies on the plate, the colonies can run together and become indistinguishable as individual colonies. In this case the plate is called confluent or Too Numerous To Count (TNTC). The countable plate has between 30 and 300 colonies. More than 300 colonies would be difficult to count, and less than 30 colonies is too small a sample size to present an accurate representation of the original sample. As stated above, the number of colonies is the number of Colony Forming Units which represents the number of microorganisms per ml.
Sample Dilution Factor (SDF)
A sample is often diluted prior to doing the serial dilutions. If it is, the sample dilution factor will be shown in the diagram as above (the 1/2 in the erlenmeyer flask is the sample dilution factor). If the sample remains undiluted, use 1/1 as the Sample Dilution Factor.
Individual Tube Dilution Factor (ITDF)
The individual tube dilution factors are a calculation of how much the sample was diluted in each individual tube. This is just the amount of sample added to the tube divided by the total volume in the tube after adding the sample. In tube I above, 1 ml of sample was added to 9 ml of water, so the ITDF for tube I is: 1ml/1ml + 9 ml = 1/10
Total Series Dilution Factor (TSDF)
The total series dilution factor is a calculation of how much the sample was diluted in all of the tubes combined. This is accomplished by multiplying each of the appropriate ISDF. This series does not include any dilutions after the countable plate. In the example above, since the countable plate was plate C, tube IV is not included in the TSDF. The TSDF for the example above is 1/10 (ITDF for tube I) x 1/10 (ITDF for tube II) x 1/6 (ITDF for tube III) = 1/600.
Plating Dilution Factor (PDF)
When the sample is plated, a dilution factor must also be calculated for this transfer. Since the object of these calculations is to determine CFU/ml, the amount plated for the countable plate is divided by 1 ml to get the PDF. In the example above, 0.3 ml from tube III was plated onto plate C, so the PDF is 0.3ml/1.0 ml = 0.3ml/1.0ml x 10/10 = 3/10.
Final Dilution Factor (FDF)
The FDF takes into account all of the above dilution factors, giving you the total dilution from the original sample to the countable plate. The FDF = SDF x TSDF x PDF, so in this example, the FDF = 1/2 x 1/600 x 3/10 = 3/12000 = 1/4000. This means that the original sample was 4000 times as concentrated as the plated sample from tube III. In other words, it would take 4 L of the sample in tube III to contain the same number of bacteria as 1 ml of the original sample.
Colony Forming Units/ml (CFU/ml) in original sample
To find out the number of CFU/ ml in the original sample, the number of colony forming units on the countable plate is multiplied by 1/FDF. This takes into account all of the dilution of the original sample. For the example above, the countable plate had 200 colonies, so there were 200 CFU, and the FDF was 1/4000.
200 CFU x 1/1/4000 = 200 CFU x 4000 = 800000 CFU/ml = 8 x 105
