Question 134: A patient's chart notes 'NPO' status before surgery. This abbreviation means:

Nothing by mouth (Correct answer)
No previous operations
Neurology pre-operative
Normal pulse oximetry

Correct answer: Nothing by mouth

NPO stands for the Latin 'nil per os,' meaning nothing by mouth. Patients are kept NPO before surgery to prevent aspiration of stomach contents during anesthesia.

Question 135: Which of the following is an unacceptable practice when documenting in a medical record due to the high risk of medication errors?

Using the abbreviation "U" for "unit" when documenting an insulin dose. (Correct answer)
Writing out "international unit" instead of using an abbreviation.
Using military time (e.g., 14:00) for entries.
Documenting "0.5 mg" instead of ".5 mg".

Correct answer: Using the abbreviation "U" for "unit" when documenting an insulin dose.

The abbreviation "U" for unit is on The Joint Commission's "Do Not Use" list because it can easily be mistaken for a "0" (zero), the number "4", or "cc", leading to a significant overdose. The other options represent safe documentation practices.

Question 136: When taking a blood pressure reading, the first Korotkoff sound heard represents:

Systolic pressure (Correct answer)

Question 143: Which tube additive prevents glycolysis and preserves glucose levels in a specimen?

Sodium citrate
Sodium heparin
EDTA
Sodium fluoride/potassium oxalate (Correct answer)

Correct answer: Sodium fluoride/potassium oxalate

Sodium fluoride inhibits the enzyme enolase to stop glycolysis, while potassium oxalate acts as an anticoagulant, making this tube the standard choice for glucose testing.

Question 144: When applying a bandage to an extremity, which direction should wrapping proceed?

Proximal to distal
Distal to proximal (Correct answer)
Only in a circular pattern
Direction does not matter

Correct answer: Distal to proximal

Bandages should be wrapped from distal to proximal (away from the heart toward the heart) to promote venous return.

Question 145: Which test is used to evaluate kidney function by measuring waste product filtration?

Liver function test
Serum creatinine and GFR (Correct answer)
Hemoglobin A1c
Prothrombin time

Correct answer: Serum creatinine and GFR

Serum creatinine and glomerular filtration rate (GFR) are primary indicators of kidney function.

Question 146: A Certified Medical Technician (CMT) is preparing to administer a medication to a resident. The Medication Administration Record (MAR) says to give 'Lisinopril 10 mg by mouth once daily'. The medication package from the pharmacy is labeled 'Lisinopril 20 mg'. What is the MOST appropriate action for the CMT to take?

Use a pill-cutter to split the 20 mg tablet in half to provide the correct 10 mg dose.
Ask the resident if they normally take a 10 mg or 20 mg tablet.
Administer the 20 mg tablet because it is the same medication.
Withhold the medication and report the discrepancy to the supervising nurse immediately. (Correct answer)

Correct answer: Withhold the medication and report the discrepancy to the supervising nurse immediately.

The 'Six Rights of Medication Administration' include the Right Drug, Right Dose, Right Time, Right Route, Right Patient, and Right Documentation. In this scenario, the dose on the pharmacy label (20 mg) does not match the dose on the MAR (10 mg). A CMT's scope of practice does not include altering medication dosages. Therefore, the safest and most appropriate action is to stop the administration process and immediately report the discrepancy to the supervising nurse for clarification and resolution.

Question 147: A specimen is rejected by the laboratory if it is received with which condition?

The tube is unlabeled or mismatched with the requisition (Correct answer)
The label matches the requisition exactly
The specimen is slightly lipemic
