Question 1 of 5.
What is the best way for a medical assistant to ensure the correct dosage of medication when administering an insulin injection?
A. Ask the patient to confirm the dose.
B. Guess the dose based on the patient's weight.
C. Check the prescription, verify the medication and dosage, and use a calibrated syringe.
D. Use the same dose for every patient.
Explanation: Medication administration requires following the "rights" of medication safety: right patient, right drug, right dose, right route, right time. To ensure the correct insulin dose, the medical assistant must first check the original provider's prescription or order. Then, they must verify the medication (e.g., type of insulin) and carefully measure the dose using an insulin syringe, which is calibrated specifically for insulin (units). Relying on the patient's memory, guessing, or using a standard dose is dangerous and violates safety protocols.
Question 2 of 5.
Holter monitor is used in diagnostic testing to primarily:
A. Monitor blood pressure levels throughout the day
B. Detect irregularities in the digestive system
C. Record the heart's activity over a period of 24 to 48 hours
D. Measure the oxygen level in the blood
Explanation: A Holter monitor is a portable electrocardiogram (ECG) device that continuously records the heart's rhythms over a 24 to 48-hour period while the patient goes about their daily activities. This is crucial for detecting arrhythmias or other cardiac events that may not occur during a standard, short-duration ECG. Monitoring blood pressure is typically done with an ambulatory blood pressure monitor, not a Holter monitor. Detecting digestive irregularities is not related to cardiac monitoring. Measuring oxygen levels is performed by a pulse oximeter.
Question 3 of 5.
What is the correct procedure for a medical assistant to sanitize an examination room prior to patient care?
A. By disposing of all paper products
B. By spraying air freshener
C. By using hospital-grade disinfectant on all surfaces
D. By using a vacuum cleaner
Explanation: Infection control protocols in healthcare settings mandate the use of hospital-grade disinfectants on all high-touch and clinical surfaces to eliminate pathogens and prevent healthcare-associated infections (HAIs). Disposing of paper products and using a vacuum cleaner are part of general cleaning but do not achieve disinfection. Spraying air freshener only masks odors and does not kill germs.
Question 4 of 5.
Where is the preferred site for capillary blood sampling?
A. The fingertip
B. The elbow
C. The wrist
D. The thumb
Explanation: The fingertip, specifically the sides of the distal end of the finger, is the preferred site for capillary blood sampling in adults and children. This area has a rich capillary network, providing an adequate blood flow for tests like glucose monitoring. The thumb has a pulse and is more sensitive. The elbow is the site for venipuncture, not capillary sampling. The wrist is not a standard site for blood collection due to thinner skin and less capillary density.
Question 5 of 5.
A patient is prescribed 2 grams of an intravenous antibiotic. If the medication is provided in 1 gram vials, how many vials should the medical assistant prepare?
A. 4 vials
B. 2 vials
C. 0.5 vials
D. 1 vial
Explanation: This is a straightforward calculation. The prescribed dose is 2 grams. Each vial contains 1 gram. Therefore, to obtain 2 grams, the medical assistant must prepare 2 vials (1 gram/vial * 2 vials = 2 grams). 4 vials would be 4 grams, which is an overdose. 0.5 vials would be 0.5 grams, which is an underdose. 1 vial would only provide 1 gram.
