A type of cell division
An organ system
The body's ability to maintain stable internal conditions (Correct answer)
A disease state

Correct answer: The body's ability to maintain stable internal conditions

Homeostasis is the body's dynamic process of maintaining stable internal conditions (temperature, pH, blood sugar) despite external changes.

Albuterol inhaler
Diphenhydramine (Benadryl)
Hydrocortisone IV
Epinephrine (EpiPen) (Correct answer)

Buccal mucosa
Sublingual glands
Tonsillar pillars and posterior pharynx (Correct answer)
Front of the tongue

Correct answer: Tonsillar pillars and posterior pharynx

Getting any signature on a form
Family approval only
Verbal agreement only
Explaining the procedure, risks, benefits, and alternatives to the patient (Correct answer)

Correct answer: Explaining the procedure, risks, benefits, and alternatives to the patient

A urinary tract infection caused by gram-negative bacteria (Correct answer)
Liver disease
Diabetic ketoacidosis
Kidney stones

Correct answer: A urinary tract infection caused by gram-negative bacteria

Nitrites on a dipstick indicate that bacteria (typically gram-negative organisms such as E. coli) have converted urinary nitrates to nitrites. This finding, especially combined with leukocyte esterase, is strongly suggestive of a UTI.

Question 101: Which of the following is a key requirement of the Clinical Laboratory Improvement Amendments (CLIA)?

CLIA applies only to Medicare-funded facilities
Only hospital labs need CLIA certification
All lab tests require physician interpretation before reporting

Elimination of all forms of microbial life, including spores (Correct answer)
Removal of visible dirt and organic matter
Reduction of microorganisms to a safe level
Killing of vegetative bacteria but not spores

Correct answer: Elimination of all forms of microbial life, including spores

Sterilization destroys all forms of microbial life, including highly resistant bacterial spores, which distinguishes it from disinfection and cleaning.

Advice given to the caller
The patient's favorite physician (Correct answer)

Correct answer: The patient's favorite physician

The patient's preference for a specific physician is not clinically relevant to documenting a telephone triage encounter.

Question 108: Which type of insurance plan requires patients to select a primary care physician and obtain referrals for specialist visits?

Indemnity plan
HMO (Correct answer)
POS plan without gatekeeper
PPO

Correct answer: HMO

HMOs (Health Maintenance Organizations) typically require a designated PCP and referrals to access specialist care.

Question 109: When a claim is denied due to a 'coordination of benefits' issue, it usually means:

The patient's deductible has not been met
The procedure code was entered incorrectly
Two insurers need to determine which pays primary and which pays secondary (Correct answer)
The provider is out of network

Correct answer: Two insurers need to determine which pays primary and which pays secondary

Coordination of benefits (COB) rules determine the order in which multiple insurance plans pay when a patient has dual coverage.

Question 110: Which blood test is the best indicator of long-term glycemic control over approximately 3 months?

Nothing, since the procedure was not done
The physician's opinion about the refusal
Only the procedure that was performed
The refusal, education provided, and patient's understanding (Correct answer)

Correct answer: The refusal, education provided, and patient's understanding

Documenting informed refusal protects the practice legally and shows that the patient was educated about risks of declining care.

Using an oral antibacterial rinse daily without exception
Keeping the head of the bed flat at 0 degrees

Correct answer: Elevating the head of the bed to 30–45 degrees

Elevating the head of the bed to 30–45 degrees is a core ventilator bundle element that reduces aspiration of gastric contents and lowers VAP risk.

Question 131: Which schedule of controlled substances has no currently accepted medical use in the United States?

Schedule I (Correct answer)
Schedule III
Schedule V
Schedule II

Correct answer: Schedule I

Schedule I substances like heroin and LSD have no accepted medical use and a high potential for abuse under the Controlled Substances Act.

2-hour value ≥153 mg/dL (Correct answer)
Any value over 100 mg/dL
1-hour value ≥130 mg/dL
Fasting value ≥110 mg/dL only

Correct answer: 2-hour value ≥153 mg/dL

Per ADA criteria, a 2-hour plasma glucose ≥153 mg/dL on the 75g OGTT is one of the thresholds for diagnosing gestational diabetes.

Question 133: Which region of the vertebral column has the greatest degree of mobility?

Cervical (Correct answer)
Lumbar
Thoracic

Wipe the touched area with an alcohol swab
Notify the physician and proceed carefully
Continue using the field if only the edge was touched
Discard the drape and establish a new sterile field (Correct answer)

Correct answer: Discard the drape and establish a new sterile field

Any break in sterile technique contaminates the entire sterile field; the drape must be discarded and a new sterile field established.

Question 138: A specimen labeled 'STAT' in the laboratory means:

Send to reference lab

Shake excess urine off the strip vigorously before reading
Dip the strip, then immediately read all pads at 30 seconds
Compare pads to the color chart at the manufacturer-specified times for each analyte (Correct answer)
Read all pads simultaneously at exactly 2 minutes

Correct answer: Compare pads to the color chart at the manufacturer-specified times for each analyte

Each analyte pad on a dipstick has its own specific reading time specified by the manufacturer (e.g., leukocytes at 2 minutes, glucose at 30 seconds). Reading all pads at the same time or too early/late leads to inaccurate results.

Question 186: Which of the following is a beta-1 selective adrenergic blocker used primarily to treat hypertension and heart failure?

Carvedilol
Metoprolol (Correct answer)
Propranolol
Labetalol

Correct answer: Metoprolol

Metoprolol is a beta-1 selective (cardioselective) beta-blocker, making it preferable in patients with respiratory conditions such as asthma.

Question 187: What is the primary purpose of HIPAA?

To prevent medical malpractice lawsuits
To regulate medical billing procedures
To ensure the safety of healthcare workers
To protect patient privacy and secure health information (Correct answer)

Patients have the right to revoke a HIPAA authorization at any time in writing, but the revocation does not apply retroactively to actions already taken in reliance on the authorization.

Question 190: Why is continuing education important in Diagnostic Procedures?

To stay current with evolving standards and practices (Correct answer)
Only for re-certification requirements
To network only
It is not important after certification

Correct answer: To stay current with evolving standards and practices

Continuing education keeps professionals updated with the latest developments, standards, and best practices in their field.

Question 191: What does informed consent require?

Getting any signature on a form
Verbal agreement only
Explaining the procedure, risks, benefits, and alternatives to the patient (Correct answer)

Cause a rapid spike in blood glucose levels (Correct answer)
Contain no carbohydrates
Lower insulin resistance over time
Are digested slowly and cause a gradual rise in blood sugar

Correct answer: Cause a rapid spike in blood glucose levels

High-GI foods are rapidly digested and absorbed, causing a quick and sharp rise in blood glucose. Diabetic patients are typically counseled to choose low-GI foods to achieve steadier blood sugar control.

Question 193: Under the Stark Law (Physician Self-Referral Law), a physician is generally prohibited from referring patients to entities:

Outside the physician's specialty
Located more than 50 miles from the physician's office
In which the physician or an immediate family member has a financial relationship (Correct answer)

To identify trends, outbreaks, and the effectiveness of prevention measures (Correct answer)
To determine which patients require isolation precautions
To create a list of all antibiotic-resistant organisms in a facility

Correct answer: To identify trends, outbreaks, and the effectiveness of prevention measures

Surveillance collects and analyzes data on infection rates to identify trends, detect outbreaks early, and evaluate the impact of infection prevention interventions.

Question 196: Which term describes the movement of a body part away from the midline?

Abduction (Correct answer)
Flexion
Circumduction
Adduction

Correct answer: Abduction

Abduction moves a limb away from the midline, while adduction moves it toward the midline.
