Q

Hematoma

A

This occurs when blood is leaking into the surrounding tissues, can be caused by advancing the needle too far or at the wrong angle, causing it to go through the vein

Q

Patients with IVs

A

It is advisable to draw blood from the opposite arm for patients who have IVs

22
Q

Collect specimens for POC testing (e.g., glucose, UA, HCG

A

Urinalysis, Hemoglobin (Hgb), Heatocrit (HCT), Coagulation (ACT, PT, APTT)

23
Q

The following are variables that would cause a specimen to be rejected (1)

A

Improper labeling or identification, Hemolysis, Expired tubes, Using the improper tube for the testing being ordered

24
Q

The following are variables that would cause a specimen to be rejected (2)

A

Clotting in anticoagulated specimens, Contaminated specimens, Insufficient volume of specimen for testing

25
Q

The following are variables that would cause a specimen to be rejected (3)

A

Inadequately filled tube, incorrect specimen collection time for timed specimens, improper handling, delayed delivery to Lab

26
Q

Stool Specimens

A

Stool or fecal specimens are collected to test for bacterial or viral intestinal infections. They may also be used to screen for occult blood, indicative of colorectal cancer.

27
Q

Semen Specimens

A

Semen specimens are used in fertility testing, to determine the effectiveness of a vasectomy, or for forensic analysis as part of a rape kit.

28
Q

Cerebrospinal Fluid Specimens

A

Cerebrospinal fluid, referred to as CSF, is fluid that circulates in the brain and spinal cord. Testing of this fluid is used to diagnose infections of the central nervous system, such as meningitis.

29
Q

Amniotic Fluid Specimens

A

Amniotic fluid is found surrounding the fetus in the amniotic sac in pregnant women. These specimens are collected through a special procedure known as an amniocentesis, which may only be performed by a physician.

30
Q

Throat Culture

A

Most commonly, these samples are used in Strep tests, which can be performed as either a rapid strep test (POC test) or as a standard bacterial culture in the laboratory.

31
Q

Nasal Swab

A

Nasopharyngeal (NP) secretions can be cultured to detect the presence of microorganisms that cause diseases such as diphtheria, influenza, meningitis, pertussis (whooping cough), and pneumonia.

32
Q

Guidelines for accurate specimen labeling

A

Patient’s full name, Patient’s ID number (if applicable), Time and date of collection, Phlebotomist’s initials.

33
Q

Vital Signs (P/Temp)

A

Pulse 60 - 80 beats per minute at rest, Temperature 97.8 - 99.1 degrees Fahrenheit.

34
Q

Temperature sites

A

Rectal 98.6F to 100.6F, Oral 97.6F to 99.6F, Axillary 96.6F to 98.6F, Tympanic Membrane 98.6F.

35
Q

Febrile

A

Presence of fever.

36
Q

Afebrile

A

Absence of fever

37
Q

Fever

A

Elevated body temperature beyond normal range.

38
Q

Intermittent

A

Fluctuating fever that returns to or below baseline then rises again.

39
Q

Remittent

A

Fluctuating fever that remains elevated; it does not return to baseline temperature.

40
Q

Continuous

A

A fever that remains constant above the baseline; it does not fluctuate.

41
Q

Vital Signs (BP)

A

Blood Pressure: normal BP is less than 120 (Diastolic) and less than 80 (systolic), Breathing 12 - 18 breaths per minute.

42
Q

Pyrexia

A

When a patient has an oral temperature of 100.8.

43
Q

Hyperpyrexia

A

When a patient presents with an oral temperature of 104°F or higher.

44
Q

Oral temperatures are not taken from the following patients (1)

A

Infants and children less than 6 years old, patients who have had surgery or a facial, neck, or mouth injury, those receiving oxygen.

45
Q

Oral temperatures are not taken from the following patients (2)

A

Those with nasogastric tubes, patients with convulsive seizures, hemiplegic patients, patients with altered mental status

46
Q

Pulse

A

The normal adult pulse rate ranges between 60 and 100 beats per minute

47
Q

Respiration

A

The normal range for adults is 12 to 20 per minute.

48
Q

Apnea

A

This is a temporary complete absence of breathing which may be a result of a reduction in the stimuli to the respiratory centers of the brain.

49
Q

Tachypnea

A

This is a respiration rate of greater than 40/min. It is transient in the newborn and maybe caused by the hysteria in the adult.

50
Q

Bradypnea

A

Decrease in number of respirations. This occurs during sleep. It may also be due to certain diseases.

51
Q

Blood Pressure

A

The measurement consists of two components: the highest (systole) and lowest (diastole) amount of pressure exerted during the cardiac cycle.
