What muscle happens to be the longest muscle in the body?

Brachii Femoris
Tibialis Anterior
Sartorius
Gastrocnemius

Correct Answer

A. Sartorius

Explanation

The correct answer is Sartorius. The Sartorius muscle is the longest muscle in the human body. It is a long, thin muscle that runs from the hip to the knee. It helps to flex and rotate the hip and knee joints.

What muscle is the site of choice for intramuscular injections greater than 1cc?

Quadricep
Tricep
Deltoid
Gluteus Maximus

Correct Answer

A. Gluteus Maximus

Explanation

The gluteus maximus is the largest muscle in the body and is located in the buttocks. It is a common site for intramuscular injections greater than 1cc because it has a large muscle mass and can accommodate larger volumes of medication. Additionally, the gluteus maximus has a thick layer of subcutaneous fat which helps to cushion the injection and reduce discomfort.

4.

The clear, pale, yellow liquid portion of blood after coagulation is?

Plasma
Blood Serum
Hemoglobin
Erythrocyte

Correct Answer

A. Blood Serum

Explanation

Blood serum is the clear, pale, yellow liquid portion of blood that remains after coagulation. It is obtained by allowing blood to clot and then separating the liquid portion from the solid components. Blood serum does not contain clotting factors, as they are removed during the coagulation process. It contains various proteins, electrolytes, hormones, antibodies, and waste products. Blood serum is often used in medical tests to analyze the levels of different substances in the body, such as glucose, cholesterol, and liver enzymes.

Which of the below is not true concerning Red Blood Cells(Erythrocytes)?

Carbon dioxide is picked up by the cell and exchanged vis the lungs
Normal cell count is higher in women than men
The cell will live anywhere from 100 to 120 days in the body
The spleen is the "graveyard" for older cells

Correct Answer

A. Normal cell count is higher in women than men

Explanation

The statement that "Normal cell count is higher in women than men" is not true concerning Red Blood Cells (Erythrocytes).

6.

What is the normal white blood cell count per cubic millimeter of blood?

6,000 to 8,000
15,000 to 20,000
250,000
4.5 to 5 million

Correct Answer

A. 6,000 to 8,000

Explanation

The normal white blood cell count per cubic millimeter of blood is 6,000 to 8,000. This range is considered to be within the normal limits for a healthy individual. White blood cells are an important part of the immune system and help to fight off infections and diseases. If the white blood cell count is too high or too low, it can indicate an underlying health condition.

The heart is enclosed in a membraneous sac called the?

Epicardium
Myocardium
Pericardium
Endocardium

Correct Answer

A. Pericardium

Explanation

The heart is enclosed in a membranous sac called the pericardium. The pericardium is a double-layered sac that surrounds and protects the heart. It consists of two layers, the fibrous pericardium, which is the outer layer, and the serous pericardium, which is the inner layer. The pericardium helps to prevent the heart from overexpanding, provides lubrication for the heart to move within the chest, and acts as a barrier against infection and inflammation.

What part of the heart receives deoxygenated blood from the body via the Superior and Inferior Vena Cava?

Left Atrium
Right Atrium
Left Ventricle
Right Ventricle

Correct Answer

A. Right Atrium

Explanation

The correct answer is Right Atrium. The right atrium receives deoxygenated blood from the body via the Superior and Inferior Vena Cava.

9.

The relaxation phase of the blood pressure is called?

Systole
Dyastole
Pulse Pressure
Median Pressure

Correct Answer

A. Dyastole

Explanation

The relaxation phase of the blood pressure is called diastole. During diastole, the heart muscles relax, allowing the chambers of the heart to fill with blood. This is the phase when the blood pressure is at its lowest point. Systole, on the other hand, is the contraction phase of the heart when blood is pumped out of the heart. Pulse pressure refers to the difference between the systolic and diastolic blood pressure, while median pressure is not a term used to describe the phases of blood pressure.

What venous system has the only veins in the bdoy that carry freshly oxygenated blood?

Hepatic
Systemic
Portal
Pulmonic

Correct Answer

A. Pulmonic

Explanation

The pulmonic venous system is the only venous system in the body that carries freshly oxygenated blood. This system carries blood from the lungs back to the heart, specifically from the pulmonary veins to the left atrium. The other options mentioned in the question, such as the hepatic, systemic, and portal venous systems, do not carry freshly oxygenated blood. The hepatic venous system carries blood from the liver to the inferior vena cava, the systemic venous system carries deoxygenated blood from the body back to the heart, and the portal venous system carries blood from the digestive organs to the liver.

What vein is most commonly used for intraveous blood draws ad infusions?

Medical Cubital
Great Sapphenous
Cephalic
Bachial

Correct Answer

A. Medical Cubital

Explanation

The correct answer is Medical Cubital. The medical cubital vein, also known as the median cubital vein, is the most commonly used vein for intravenous blood draws and infusions. It is located in the antecubital fossa, which is the front part of the elbow. This vein is preferred because it is large, easily accessible, and less prone to damage or complications compared to other veins in the arm. It is often used for procedures such as blood tests, IV medications, and fluid administration.

What is another name for the voice box?

Larynx
Pharynx
Vocal Cords
Trachea

Correct Answer

A. Larynx

Explanation

The larynx is another name for the voice box. It is a part of the respiratory system located in the throat. It contains the vocal cords, which are responsible for producing sound and enabling speech. The larynx also plays a crucial role in protecting the airway during swallowing, preventing food and liquids from entering the lungs.

What is dome shaped and separated the thoraci and Abdominal cavaities?

Mediastinum
Intercostal Muscles
Diaphragm
Lungs

Correct Answer

A. Diaphragm

Explanation

The diaphragm is a dome-shaped muscle that separates the thoracic and abdominal cavities. It plays a crucial role in respiration by contracting and flattening when we inhale, allowing the lungs to expand and fill with air. When we exhale, the diaphragm relaxes and returns to its dome shape, pushing the air out of the lungs. Therefore, the diaphragm is responsible for the separation and movement of air between the thoracic and abdominal cavities.

The amount of air left in the lungs after forec expiration is about 1200 cc and is known as?

Inhaled Air
Exhaled Air
Inspiratory Reserve Volume
Residual Air

Correct Answer

A. Residual Air

Explanation

Residual air refers to the amount of air that remains in the lungs after forceful expiration. This residual air is approximately 1200 cc. It is important to note that residual air is not easily expelled from the lungs and is necessary to maintain lung function and keep the alveoli open.

What type of respirations increase with forec and frequency up to a certain point, the decrease until they cease altogether?

Eupnea
Rales
Cheyene-Stokes
Dyspnea

Correct Answer

A. Cheyene-Stokes

Explanation

Cheyene-Stokes respirations are characterized by a pattern of increasing depth and frequency of breaths, followed by a gradual decrease until breathing temporarily stops. This pattern repeats itself in a cycle. Cheyene-Stokes respirations are often seen in individuals with severe heart failure or brain damage.
