Which of these would be the best choice to administer an intradermal injection?
- A.
Insulin syringe
- B.
Tuberculin syringe
- C.
Hypodermic syringe
- D.
A closed injection system
Correct Answer
B. Tuberculin syringeExplanation
A tuberculin syringe would be the best choice to administer an intradermal injection.

D. B or CExplanation
The sensitivity switch on an ECG machine controls either the amplitude or the gain. The amplitude refers to the height of the ECG waveform, while the gain determines the sensitivity of the machine to detect and display small changes in the electrical activity of the heart. Adjusting the sensitivity switch allows the user to either amplify or attenuate the ECG signal, making it easier to analyze and interpret the data.Rate this question:

The electrical force or vector produced by ventricular depolarization has two components; one is the magnitude of the force, and the other is ____________.
- A.
Defibrillation
- B.
Shock Treatment
- C.
V Tach
- D.
Scintillation
Correct Answer
A. DefibrillationExplanation
The electrical force or vector produced by ventricular depolarization has two components; one is the magnitude of the force, and the other is defibrillation. Defibrillation is a medical procedure used to restore the normal rhythm of the heart by delivering an electrical shock to the heart. It is used to treat life-threatening conditions such as ventricular fibrillation or pulseless ventricular tachycardia. Therefore, in the context of the given question, defibrillation is the correct answer as it represents the second component of the electrical force or vector produced by ventricular depolarization.Rate this question:

When preparing a blood smear from a skin puncture you should _____ the first drop.
- A.
Collect
- B.
Use
- C.
Wipe away
- D.
Wash off
Correct Answer
C. Wipe awayExplanation
When preparing a blood smear from a skin puncture, it is recommended to wipe away the first drop of blood. This is because the first drop may contain tissue fluid or contaminants from the skin's surface, which can interfere with the accuracy of the blood sample. By wiping away the first drop, a cleaner and more representative sample can be obtained for the blood smear.Rate this question:

When there is no variation of R-R intervals in an ECG reading it is called ________.
- A.
Irregular with a pattern
- B.
Absolutely regular
- C.
Essentially regular
- D.
Totally irregular
Correct Answer
B. Absolutely regularExplanation
When there is no variation of R-R intervals in an ECG reading, it is called "absolutely regular" because the R-R intervals refer to the time between consecutive R waves, which represent the ventricular depolarization. In a normal ECG reading, there should be slight variations in these intervals, indicating a regular but not completely constant rhythm. However, when there is no variation, it suggests that the heart is beating with a constant and predictable pattern, hence the term "absolutely regular."Rate this question:
