medical assisting test review Flashcards
Height and weight measurements are used to determine what?
-They are used for calculating dosage for medicine, performing and evaluating lab tests, and also to help ensure children are growing properly.
During daily weight checks, list 6 points that should be noted:
-use the same scale each time
-ensure the scale is balanced
-weight at the same time of the day
-weigh before any intake
-patient should wear the same or little amount of clothing
-ask the patient to void before (use the restroom)
What 2 circumference measurements should be recorded in infants and toddlers?
head and chest
Any head circumference that measures above the 95th percentile usually indicates what?
hydrocephalus; an accumulation of fluid in the brain
A below-normal value for head circumference can be an indication of what?
microcephaly; small brain, premature closure of the fontanels
Describe the “Horizontal recumbent (supine”) position:
-patient laying flat on their back
Describe the “Prone” position”
-patient would be laying flat on their stomach
Describe the “Semi-fowler’s” position: what is this position used for?
-patient would be laying on their back at a 45 degree angle
Describe the High Fowler’s position; what is this position used for?
-pateint would be laying on their back at a high angle such as 90 degrees. this position is used to help breathing
What do the top and bottom numbers represent in a visual acuity reading (for example,20/20)?
-top: the distance the patient is from the chart
-bottom: the height of the characters that the patient can read from a distance
What are hemostats used for?

What is the purpose of a needle holder?
-used to hold and guide a suturing needle during surgical procedures like wound closure
What does the P wave represent?
-the P wave represents the depolarization of the atria (the heart’s upper chambers). This means it shows the electrical activity as it’s firing throughout the atria, preparing them to contract and pump blood into the ventricles.
What does the QRS complex represent?
-represents ventricular depolarization and the subsequent ventricular contraction. It signifies the electrical signal spreading through the ventricles of the heart, leading to their contraction and the pumping of blood.
