PTCB Practice Test 4

The aseptic technique is a medical procedure/technique used to keep medical equipment sterile in order to prevent contamination that could lead to infection. This technique ensures that all equipment, such as needles and syringes, are free from any microorganisms that could potentially cause harm to the patient. By maintaining a sterile environment, healthcare professionals can minimize the risk of infections during medical procedures and ensure the safety of the patients.

An ampule is a small glass container that is sealed and holds a single dose of medication. It is designed to be easily broken open so that the medication can be accessed. The glass container helps to maintain the sterility and integrity of the medication until it is ready to be used. Ampules are commonly used in healthcare settings to store and administer medications, particularly for injections.

A filter needle is a type of hypodermic needle that has a small filter system built into it. This filter system is designed to prevent the aspiration of small glass particles from ampules into the syringe. This is important because glass particles can be harmful if injected into the body. By using a filter needle, healthcare professionals can ensure that the medication being drawn from an ampule is free from any potential contaminants.

A crash cart is a cart with a set of trays, shelves, and drawers on wheels that is used in hospital emergency rooms. It is used to dispense medication on-site during emergencies to save someone's life. It is not a cart of medications kept aside for EMS professionals or a cart kept in storage with backup medication. The trays, shelves, and drawers on the cart are organized with various medications and medical supplies that may be needed in emergency situations. The cart is easily accessible and can be quickly wheeled to the location where it is needed.

MSDS stands for Material Safety Data Sheet, which is a document that provides important information about the health and safety hazards of chemicals in the workplace. It includes information about the chemical composition, physical and chemical properties, potential hazards, and precautions for safe handling, storage, and disposal. MSDS is used to ensure the safety of workers and to provide guidance on how to handle and respond to chemical exposures or spills in the workplace.

The gauge of a needle refers to its thickness. A larger gauge means a smaller diameter, indicating a thinner needle. Therefore, the statement "The larger the gauge of needle, the thinner the needle is" is true.

A prefilled syringe is a sterile disposable syringe/needle unit that is packaged to supply a single dose of medication. It is designed to be used once and then discarded, ensuring the medication is administered in a safe and sterile manner. This eliminates the need for manual drawing of medication from a vial, reducing the risk of contamination and dosage errors.

A glass vial is a container made of glass with a rubber stopper on top. It is designed to hold one dose of injectable medication. To withdraw the medicine, a sterile needle is inserted through the rubber stopper.

The correct answer is "Measurement indicating the diameter of the lumen of a hypodermic needle used for parenteral administration." The term "gauge" is commonly used in the medical field to describe the size or diameter of a needle. It is an important measurement as it determines the flow rate and the size of the puncture made by the needle.

The generic name for the cancer medication Taxotere is docetaxel. This medication is commonly used in the treatment of various types of cancer, including breast, lung, prostate, and stomach cancer. Docetaxel belongs to a class of drugs called taxanes, which work by inhibiting the growth of cancer cells and preventing them from dividing and spreading. It is administered intravenously and is often used in combination with other chemotherapy drugs to increase its effectiveness in killing cancer cells.

When opening an ampule, it is necessary to gently tap the top of the ampule. This tapping action helps to ensure that the medication inside the ampule flows down into the larger bottom part of the glass container. By tapping the top, the medication is directed towards the bottom where it can be easily accessed and withdrawn for use.

1cc = 100 units

Insulin rule: 1cc = 100 units

Taking too much insulin can cause low blood glucose levels, also known as hypoglycemia. Insulin helps to lower blood sugar levels, but when too much is taken, it can cause an excessive drop in blood sugar levels. This can lead to symptoms such as dizziness, confusion, sweating, and even loss of consciousness. It is important for individuals with diabetes who take insulin to carefully monitor their blood sugar levels and adjust their insulin dosage accordingly to avoid hypoglycemia.

A 1 cc syringe is used to deliver a TB (tuberculin) skin test intradermally. This is because the TB skin test requires a small amount of the tuberculin antigen to be injected just under the skin. A 1 cc syringe allows for precise and accurate delivery of this small volume. A larger syringe, such as a 5 cc syringe, would not be suitable for this test as it may deliver too much antigen and cause inaccurate results. Similarly, a 0.5 cc syringe may not provide enough volume for proper administration of the test.
