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 because it has a small, fine needle that allows for precise delivery of medication into the dermis, which is the layer of skin just below the epidermis. This is important for intradermal injections, as they are typically used for skin testing, such as tuberculosis testing or allergy testing, where a small amount of medication needs to be injected just under the skin. The other options, such as an insulin syringe or a hypodermic syringe, are not designed for intradermal injections and may not provide the same level of accuracy and control. A closed injection system is not relevant to this question as it does not specify the type of injection being administered.Rate this question:

The physician has ordered 50 mg of Demerol to be given to a patient. The concentration on hand is 100mg/ml. How many cc's of Demerol will be injected?
- A.
0.5 cc
- B.
1.0 cc
- C.
1.5 cc
- D.
0.25 cc
Correct Answer
A. 0.5 ccExplanation
The physician has ordered 50 mg of Demerol to be given to a patient, and the concentration of Demerol on hand is 100mg/ml. To determine how many cc's of Demerol will be injected, we can use the equation: concentration (mg/ml) x volume (ml) = dose (mg). Rearranging the equation, we have: volume (ml) = dose (mg) / concentration (mg/ml). Plugging in the values, we get: volume (ml) = 50 mg / 100 mg/ml = 0.5 ml. Therefore, 0.5 cc's of Demerol will be injected.Rate this question:

- B.
Decongestant
- C.
Antihistamine
- D.
Bronchodilator
Correct Answer
B. 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 symptoms such as a stuffy or runny nose. Unlike suppressants, which generally work by suppressing cough reflexes, decongestants specifically target nasal congestion. Antihistamines, on the other hand, are used to treat allergies and may have some decongestant properties as well. Bronchodilators are medications that help to open up the airways in the lungs and are primarily used to treat conditions such as asthma and chronic obstructive pulmonary disease (COPD).Rate this question:

Correct Answer
A. UniformExplanation
A premature ventricular contraction (PVC) is an abnormal heartbeat that originates in the ventricles of the heart. When the QRS complex, which represents the electrical activity of the ventricles, has the same configuration each time it appears, it is called "uniform." This means that the PVCs have a consistent appearance, indicating a regular pattern in their occurrence. This term helps to differentiate it from other types of PVCs that may have varying configurations, suggesting a different underlying cause or rhythm disturbance.Rate this question:

On an ECG machine, the sensitivity switch controls the ________.
- A.
Start
- B.
Amplitude
- C.
Gain
- D.
B or C
Correct Answer
D. B or CExplanation
The sensitivity switch on an ECG machine controls either the amplitude or the gain. By adjusting the sensitivity, the user can control the size of the electrical signals displayed on the ECG graph. This allows for a clearer and more detailed representation of the heart's electrical activity. The amplitude refers to the height of the signal, while the gain refers to the overall amplification of the signal. Therefore, either option B (amplitude) or option C (gain) could be the correct answer.Rate this question:

The electrical force or vector produced by ventricular depolarization has two components; one is the magnitude 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 force, and the other is defibrillation. Defibrillation is a medical procedure used to restore the normal rhythm of the heart by delivering an electric shock to the heart. It is used to treat life-threatening cardiac arrhythmias such as ventricular fibrillation and pulseless ventricular tachycardia. Therefore, defibrillation is the correct answer as it is directly related to the electrical force 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 debris that 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:
