NR. 167 A condition marked by a decrease in the number of red blood cells is known as:

Anemia

Leukemia

Thrombocytopenia

Polycythemia

Anemia is a condition indicated by a deficiency of red blood cells and hemoglobin in the blood. Leukemia is a type of cancer characterized by an increase in the number of white blood cells. Thrombocytopenia is marked by a decrease in the number of platelets. Polycythemia is a type of cancer that results in an excessive number of red blood cells.

NO.168 During venipuncture, if the needle appears to be in the vein but no blood is flowing and a slight vibration or quiver of the needle is noted, the most appropriate initial response is to:

Immediately discontinue the venipuncture,

Remove the vacuum tube, pull back slightly on the needle, and reinsert the vacuum tube.

Rotate the needle slightly to the right or left.

Remove the vacuum tube, gently insert the needle further, and reinsert the vacuum tube.

During venipuncture, if the needle appears to be in the vein but no blood is flowing and a slight vibration or quiver of the needle is noted, the most appropriate initial response is to remove the vacuum tube, pull back slightly on the needle, and reinsert the vacuum tube. If this is not successful, the venipuncture should be discontinued and another site attempted. The lack of blood flow and vibration or quiver suggest that the needle is in a valve and the valve is attempting to open and close.

NR. 169 Which pattern of antecubital veins is predominant in most populations?

The M pattern

The Y pattern

The H pattern

An atypical pattern

The pattern of antecubital veins that is predominant in most populations is the H pattern, also known as the N pattern. The veins that are most prominent in the H pattern include the cephalic, median cubital, and basilic veins. The veins that are most prominent in the M pattern, also known as the Y pattern, include the cephalic, median cephalic, median basilic, and basilic veins. Although these tv.ro patterns are the most common, some patients have atypical patterns of veins rather than the H or M configuration.

NR. 170 The primary function of leukocytes is to:

Oxygenate the cells.

Carry solutes.

Promote coagulation.

Neutralize or destroy pathogens.

The primary function of leukocytes (white blood cells) is to neutralize or destroy pathogens through phagocytosis (engulfing and destroying) or the production of antibodies. There are five types of leukocytes:

NR. 171 The total blood volume of a child is approximately:

65-70 mL/kg

75-80 mL/kg

85-105 mL/kg

100-120 mL/kg

The total blood volume of a child is approximately 75-80 mL/kg. Blood volume is greater in a premature neonate, ranging from 89 mL/kg to approximately 105 mL/kg. The volume of blood in a full-term neonate is approximately 82-86 mL/kg. Blood volume peaks at approximately 4 weeks of age and then decreases over the next few months. The total volume ofblood in an adult is typically 65-70 mL/kg.

NO.172 The total number of muscles in the body is:

566

656

556

560

There are a total of 656 muscles in the body.

NR. 173 When collecting a specimen from a patient in a long-term-care facility, the first thing the phlebotomist should do is to:

Knock on the patient’s door.

Check in at the nursing station.

Contact the patient prior to arrival.

Enter the patient’s room.

When collecting a specimen from a patient in a long-term-care facility, the first thing that the phlebotomist should do is to check in at the nursing station. The phlebotomist needs to ask for information about any special concerns regarding the patient, such as the need for assistance if the patient is confused or any type of restriction that applies to the patient. As in any other setting, the phlebotomist should always knock on the door or announce his or her arrival before entering the room and explain the purpose of the visit.

NR. 174 A primary function of the endothelium (tunica interna) of an artery is to:

Prevent blood clotting.

Promote blood clotting.

Provide elasticity to accommodate blood flow.

Attach the artery to surrounding tissue.

A primary function of the endothelium (tunica interna-the inner layer) of an artery is to prevent blood clotting through secretion of biochemicals that inhibit platelet aggregation. The endothelium provides a smooth surface for the blood to flow through and secretes substances that constrict or dilate the arteries. The middle layer is the tunica media, which is the thickest part of the arterial wall. The tunica media contains muscle and connective tissue to provide strength and elasticity. The tunica externa (the outer layer, aka tunica adventitia), attaches the artery to the surrounding tissue.

NR. 175 When collecting a blood specimen for trace elements such as zinc, the appropriate tube type is:

Plastic

Metal-free

Glass

Stopper-free

When collecting a blood specimen for trace elements, such as zinc, selenium, or mercury, the appropriate tube type is metal-free. These are specialty tubes designed so that they do not contaminate the sample with trace elements (including, but not limited to, metals) that are typically found in glass and plastic containers. These tubes usually have royal-blue tops and are available with EDTA or heparin, or they are free of additives. Samples for lead testing are collected in tan- topped tubes containing K2 EDTA.

NR. 176 An individual with which type of blood can be a blood donor to individuals with any of the four blood types?

Type A

Type B

Type AB

Type O

Because type O blood lacks antigens, an individual with type O blood can be a donor to individuals with any of the four blood types: thus, a person with type O blood is known as a universal donor.

NO.177 What percentage of the blood is composed of plasma?

35%

45%

55%

65%

NO.178 A vital function of the capillaries is to:

Control the flow of blood.

Exchange gases, nutrients, and metabolic by-products.

Stabilize the blood pressure.

Secrete substances that prevent the clotting of blood.

A vital function of the capillaries is to exchange gases (carbon dioxide [C02J for oxygen), nutrients, and metabolic by-products (wastes). Capillaries are extensions of arteriole endothelium and are tiny, thin-walled vessels that carry a mixture of arterial and venous blood. The walls of the capillaries are semipermeable, with tiny openings where endothelial cells in the walls overlap. The density of capillary networks depends on the metabolism of the tissue, so capillaries are dense in muscle and nerve tissue and are less dense in cartilage, the epidermis, and the corneas.

NO.179 Which of the following evacuated collection tubes should NOT be used to collect a specimen for a BMP?

Red-capped with clot activator

Red/BIack -capped SST

Lavender-capped

Green-capped

The evacuated collection tube that cannot be used to collect a specimen for a BMP is the lavender-capped collection tube, which contains an anticoagulant (EDTA) and is used to collect a whole blood sample for the CBC or its components. Red-capped collection tubes with a clot activator, red/black SST, and green-capped tubes can all be used. The BMP includes the tests on the electrolyte panel as well as the BUN, Ca (calcium), creatinine, and glucose.

NO.180 All of the following statements regarding tourniquet application are true EXCEPT:

The patient should be told to pump his fist.

A tourniquet may be applied over the patient’s sleeve.

Two tourniquets may be used together.

A tourniquet should not be applied over an open sore.

When applying a tourniquet, fist pumping should be discouraged, as it may make vein location more difficult or cause changes in blood components that may affect test results. A tourniquet may be applied over a patient’s sleeve if the sleeve is too tight and cannot be rolled up far enough. Because a tourniquet may have a tendency to roll or twist on the arm of an obese patient two tourniquets may be stacked and used together. A tourniquet should never be placed over an open sore.

NO.181 For blood collection with the butterfly infusion set in a child, the phlebotomist should use a:

23-gauge needle with a 5-mL tube

21-gauge needle with a 5-mL tube

23-gauge needle with a 2-mL tube

22-gauge needle with a 2-mL tube

For a pediatric patient a 23-gauge needle with a 2-mL tube should be used for blood collection using a butterfly infusion set. Use of a 5-mL tube with a 23-gauge needle may cause vein collapse or hemolysis of the specimen.

NO.182 All of the following are indicative of a UTI EXCEPT:

Leukocytes

Nitrites

Protein

Glucose

A positive nitrite test in conjunction with a positive leukocyte test is indicative of urinary tract infection (UTI): a urine culture positive for blood or protein is also indicative of UTI. Glucose in the urine may be indicative of diabetes mellitus.
