Flashcards in Chapter 6 Vital Signs and Oxygen Administration Deck (17):

Which of the following are essential parts of the initial assessment of a patient who is in the diagnostic imaging department for an invasive procedure?

- Taking a blood pressure
- Taking a pulse
- Taking a respiration rate


Why is the initial assessment defined in Question no. 1 so important to perform?

To establish baseline


Systolic blood pressure can be defined as:

The highest point reached during contraction of the left ventricle


What range of breaths per minute is the normal adult respiratory rate?

15 to 20


An adult patient is considered to by hypertensive or to have hypertension if the systolic blood pressure and diastolic blood pressure are consistently greater than:

140 systolic and 90 diastolic


Oxygen can be toxic to patients if it is incorrectly used. State two reasons why this is so.

Oxygen is considered a medicine, and too much can cause severe lung damage, especially since aerobic infections can thrive with extra oxygen. If the patient has COPD, then the extra oxygen may depress the respiratory system, causing the patient to go into respiratory arrest


A patient may be considered to have tachycardia if the pulse rate is higher than:

100 beats/min


Which of the following items must be in the diagnostic imaging department and in working order?

- Oxygen delivery system
- Blood pressure monitoring equipment


What is the normal oral body temperature of an adult?

97.8 to 99 degrees Fahrenheit.


Brachial artery

Point where the blood pressure is most often measured



Measures apical pulse



Measures blood pressure


Clinical thermometer

Measures body temperature


Radial artery

Point where the pulse is most often measured


Name the two most commonly used oxygen delivery systems.

- Nasal cannula
- Face mask


List the hazards of oxygen administration.

To high of an oxygen concentration may cause reversible tracheobronchitis

Oxygen is highly combustible


Explain why the pulse rate goes up when the blood pressure drops.

Because when the blood pressure goes down, it usually means that there isn't enough blood to need a lot of pressure. If there isn't a lot of blood to pump, there isn't a lot of oxygen getting delivered. That means the heart pumps faster to get oxygen in and carbon dioxide out, which leads to a higher pulse rate.
