A tourniquet should be on the patient’s arm no longer than __________.
-
1 minute
-
2 minutes
-
Three minutes
-
Four minutes
Correct Answer
A. 1 minuteExplanation
A tourniquet should be on the patient's arm no longer than 1 minute because prolonged use can lead to tissue damage, nerve injury, and other complications. The pressure applied by the tourniquet restricts blood flow to the area, which is necessary in certain medical procedures or to control bleeding. However, leaving the tourniquet on for too long can cause ischemia, where the tissues are deprived of oxygen and nutrients. This can result in tissue death and other serious consequences. Therefore, it is crucial to limit the use of a tourniquet to minimize the risk of complications.Rate this question:

-
Use a lifting motion to move away from the skin
Correct Answer
A. Work in a circle from the center to the peripheryExplanation
When cleansing the typical venipuncture site, it is recommended to work in a circle from the center to the periphery. This technique ensures that the entire area is thoroughly cleansed and reduces the risk of contamination. By starting at the intended site of the draw and working in a circular motion, any bacteria or dirt present on the skin will be effectively removed. This method helps to maintain a sterile environment and minimize the chances of infection during the venipuncture procedure.Rate this question:

What is a break in a bone without penetration of the skin surface over the fracture site called?
-
Open fracture
-
Spiral fracture
-
Greenstick fracture
-
Closed fracture
Correct Answer
A. Closed fractureExplanation
A closed fracture refers to a break in a bone without any penetration of the skin surface over the fracture site. In this type of fracture, the bone is broken but the skin remains intact. This is different from an open fracture, where the broken bone pierces through the skin. Spiral fracture refers to a type of fracture where the bone is twisted apart, while a greenstick fracture is an incomplete fracture commonly seen in children where the bone bends and cracks but does not break completely.Rate this question:

How should a 24-hour urine specimen be stored during collection?
-
At body temperature
-
In a refrigerator
-
At room temperature
-
In a freezer
Correct Answer
A. In a refrigeratorExplanation
A 24-hour urine specimen should be stored in a refrigerator during collection. This is because refrigeration helps to preserve the integrity of the specimen by slowing down the growth of bacteria and preventing the breakdown of certain components. Storing the specimen at body temperature, in a freezer, or at room temperature may lead to changes in the composition of the urine, which can affect the accuracy of any tests that need to be performed on the specimen.Rate this question:

Which of the following areas should be swabbed when obtaining a specimen for a throat culture?
-
Back of the throat and tonsillar area
-
Nasopharynx and epiglottis
-
Cheeks and tongue
-
Gums and tongue
Correct Answer
A. Back of the throat and tonsillar areaExplanation
When obtaining a specimen for a throat culture, the back of the throat and tonsillar area should be swabbed. This is because these areas are more likely to harbor bacteria or viruses that may be causing an infection. Swabbing these areas allows for the collection of a sample that is more likely to accurately represent the presence of pathogens in the throat. Swabbing other areas such as the nasopharynx, epiglottis, cheeks, tongue, gums, or other parts of the mouth may not provide an accurate representation of the pathogens present in the throat.Rate this question:

A drug that decreases mucus in the nasal passages is called a(n) __________.
-
Suppressant
-
Decongestant
-
Antihistamine
-

Correct Answer
A. DecongestantExplanation
A drug that decreases mucus in the nasal passages is called a decongestant. Decongestants work by constricting the blood vessels in the nasal passages, reducing swelling and congestion. This helps to relieve nasal congestion and improve airflow. Unlike antihistamines, which mainly target allergies, decongestants specifically target nasal congestion. Suppressants and bronchodilators are not specifically designed to decrease mucus in the nasal passages.Rate this question:

Correct Answer
A. UniformExplanation
A premature ventricular contraction (PVC) is an abnormal heart rhythm where the ventricles contract earlier than expected. In this case, the QRS complex, which represents the electrical activity of the ventricles, has the same configuration each time it appears. This suggests that the PVCs are originating from the same source and have a consistent pattern. Therefore, the term "uniform" accurately describes this type of PVC.Rate this question:

Which of these would be the best choice to administer an intradermal injection?
-
Insulin syringe
-
Tuberculin syringe
-
Hypodermic syringes
-
A closed injection system
Correct Answer
A. Tuberculin syringeExplanation
A tuberculin syringe would be the best choice to administer an intradermal injection. Intradermal injections are shallow injections that are administered just below the epidermis, so a smaller syringe like a tuberculin syringe is ideal. Tuberculin syringes are designed specifically for this purpose, with a small volume capacity and a very fine needle that allows for precise and accurate delivery of the medication into the dermis. Insulin syringes are designed for subcutaneous injections, hypodermic syringes are designed for intramuscular or subcutaneous injections, and a closed injection system is not typically used for intradermal injections.Rate this question:
