After reviewing Ms. Stewart's medical history, you notice that she checked "yes" next to hypertension. You take her blood pressure, and your reading is 143/95. Is this considered hypertensive? If so, what stage is her hypertension?
143/95 is considered Stage 1 hypertension.
What is the normal respiration rate for a young child through the teenage years?
18 to 30 breaths per minute.

What does the systolic pressure reflect?
The amount of pressure that is required for the left ventricle of the heart to compress or push oxygenated blood out into the blood vessels.
Describe the following five phases of Korotkoff sounds in blood pressure measurement. Phase II:
The cuff deflates, and more blood flows; a swishing sound may be heard; this sound is softened and becomes prolonged into a murmur.
Which dental team member is usually responsible for obtaining a patient's vital signs?

When is the pulse taken using the radial artery?
In the dental office.
What happen to a person's temperature during illness?
It increases to fight bacteria and viruses and to produce internal heat for warmth.
What will simplify the process of taking a patient's pulse?
Observing a watch or a clock with a second hand while palpating the pulse.

Describe the three types of characteristics you are looking for when taking a patient's pulse.
When taking a patient's pulse, you are looking for the rate, which is the number of beats that occur during the counting period, the rhythm, which describes the pattern of the beats, and the volume, which is the force of the beat.
When may an ECG/EKG be required for dentistry?
When a patient is undergoing general anesthesia or IV sedation in a hospital or outpatient setting as a preventative measure. This can allow the dentist to follow the patient's cardiac activity throughout a procedure.
How should the patient be positioned to taking the radial pulse?

If taking a blood pressure more than one time, how much time should elapse before it is taken again?
A minimum of 10 minutes.
When is a person's body temperature the lowest and when is it the highest?
A person's lowest body temperature occurs in the early morning hours, and the highest temperature occurs in the evening.
Which vital sign is described as the rhythmical expansion of the artery every time the heart beats?
A pulse.
What are Korotkoff sounds?
A series of sounds produced by the blood rushing back into the brachial artery.
Is respiration voluntary or involuntary?
An involuntary response and a voluntary function.
Where is the carotid artery located?
Alongside the patient's larynx.
What device is used in many practices to simplify and speed the recording of a blood pressure?

What does a record of the patient's vitals signs provide the dental team?
Assurance regarding the patient's well-being and health status.
Describe the following five phases of Korotkoff sounds in blood pressure measurement. Phase I:
Blood is beginning to flow back into the artery and can be heard as a sharp tapping sound; this is the systolic blood pressure reading.
Describe the following five phases of Korotkoff sounds in blood pressure measurement. Phase IV:

Consists of the cuff, which is a cloth wrap that holds an inflatable rubber bladder, the rubber bulb, which is attached to the cuff with rubber tubing.
What factors may affect a patient's vital signs, and how?
Hot or cold beverages which can alter a patient's oral temperature, fear of a procedure which can increase blood pressure and respiration, and exercise which can elevate temperature, pulse, respiration, and blood pressure.
When should vital signs routinely be taken?
If this is the patient's first visit, 6-month recall, or a medical emergency.
What characteristics are noted during the taking and recording of respiration?
Include rate, which is the total number of breaths per minute, rhythm, which refers to the breathing pattern, and depth, which is the amount of air that is inhaled and exhaled during a breath.
What characteristics should be noted when obtaining and recording the patient's pulse?
Include rate, which is the number of beats that occur during the counting period, rhythm, which describes the pattern of beats, and volume, which is the force of the beat.
What are the advantages of using a tympanic thermometer?
Include the fact that the ear canal is a protected cavity so the reading is not affected by an open mouth, hot or cold drinks, or nose congestion; it also has a much smaller probe and can provide a reading within 2 seconds; in addition, the risk of spreading communicable diseases is greatly reduced because the covered probe of the thermometer does not actually touch the eardrum.
How does the average temperature for an infant and young child compare to an adult?
It is higher in infants and younger children than in adults.
Why might the tympanic method be more accurate?
Its rapid measurement causes less patient movement to occur.
What is the normal range of blood pressure of adults?
Less than 120 systolic and less than 80 diastolic.
Ms. Stewart is a new patient to your clinic, and you have just reviewed her medical-dental history. Where would you take Ms. Stewart to take her vital signs? In what order would you take them for optimum time efficiency?
Mrs.Stewart's vital signs would be taken inside one of the treatment rooms while she is sitting down. I would begin by taking her temperature, blood pressure, checking her pule, and then observing her respiration in order to be time efficient.
What happens during respiration?
Oxygen is taken into the body, and carbon dioxide is released as a waste product.
Describe the process of taking the radial pulse.
Place your index finger and middle fingers lightly on the patient's wrist between the radius and the tendon. (30 sec x2)
Since patients may consciously change their breathing pattern if they know their breaths are being monitored, what is the best technique when taking a patient's respiration?
Refocus your attention to their chest while you still have your fingers positioned on their wrist.
What care needs to be taken when using a digital thermometer?
Remember the timed feature of the digital thermometer because you may attain an inaccurate reading if the battery is low.
What is included in vital signs?
Taking and recording a person's temperature, pulse, respiration, and blood pressure.

Taking measurements multiple times.
What may be necessary to obtain an accurate or average blood pressure reading?
Taking several blood pressure readings.

Temperature.
Describe the systolic pressure?
The first sound which is a sharp tapping sound and is the first and larger number recorded.
What does the diastolic pressure reflect?
The heart muscle at rest, allowing the heart to take in blood to be oxygenated before the next contraction occurs.
Describe the diastolic pressure.
The last sound which is a soft tapping sound and is the second and lower number recorded.
Which of these instruments is the blood pressure cuff and meter, and is used to measure the blood pressure?

Your next patient would be classified as obese. As you seat him in the dental chair, you do not feel comfortable about taking his vital signs. What are some of the obstacles that should be considered when taking vital signs on an obese patient?
With obese patients, you should be aware that you have to manipulate the skin occasionally to get a correct reading. You may have to take several readings.
