pp v.2

Primary first-aid action used to control severe external bleeding

Applying direct pressure

Reason for prohibiting lip balm application in a laboratory setting

It creates a potential contamination and infection-control hazard.

Type of blood that capillary blood obtained via skin puncture most closely resembles

Arterial blood

Primary purpose of warming the puncture site before capillary blood collection

To increase blood flow to the area

CLSI-recommended maximum depth for an infant heel puncture

$$2.0\,mm$$

Condition screened for using PPD testing

Tuberculosis (TB) infection

General sequence for donning personal protective equipment (PPE)

$$\text{Gown} \rightarrow \text{Mask} \rightarrow \text{Gloves}$$

Reason for avoiding the pinky finger during capillary blood sampling

Example of a work-practice control that reduces bloodborne pathogen exposure

Hand decontamination

Mode of transmission when infectious micro-organisms reach mucous membranes via coughing or sneezing

Droplet transmission

Reason EDTA microcollection containers are filled first during capillary draw

To minimize platelet clumping

Safest anatomical location for performing an infant heel puncture

Lateral plantar surface of the heel

Primary reason for wiping away the first drop of blood during a skin puncture

To minimize tissue fluid contamination

Microcollection tube top color used to collect a Complete Blood Count (CBC)

Lavender (purple) top

Primary risk of exceeding recommended lancet insertion depth during capillary puncture

Bone injury (such as osteomyelitis or osteochondritis)
