Assistant Practice Questions, Answers & Detailed Rationales
(2026/2027)
Question 1
Under the Health Insurance Portability and Accountability Act (HIPAA)
Privacy Rule, which of the following actions by a medical assistant
constitutes a permissible disclosure of Protected Health Information
(PHI) without patient authorization?
• A. Providing a patient's complete medical history to an employer
for hiring evaluation.
• B. Sharing diagnostic test results with a family member who calls
the clinic without prior patient designation.
• C. Disclosing treatment, payment, and healthcare operations
(TPO) information to another covered entity directly involved in
the patient's care.
• D. Discussing a patient's diagnosis in a public waiting room where
other patients can overhear.
Correct Answer: C. Disclosing treatment, payment, and healthcare
operations (TPO) information to another covered entity directly
involved in the patient's care.
Detailed Rationale: HIPAA allows covered entities to share PHI for
treatment, payment, and healthcare operations (TPO) without written
authorization to ensure continuity of care and proper billing. All other
options represent unauthorized or unsafe disclosures.
,Question 2
When measuring the vital signs of an adult patient, which of the
following is considered a normal, healthy resting blood pressure reading
according to standard guidelines?
• A. 140/90 mmHg or higher
• B. Less than 120/80 mmHg
• C. 160/100 mmHg
• D. 130--89 mmHg
Correct Answer: B. Less than 120/80 mmHg
Detailed Rationale: According to current cardiovascular guidelines,
normal adult resting blood pressure is defined as less than 120 mmHg
systolic and less than 80 mmHg diastolic.
Question 3
What is the standard anatomical site and recommended needle
insertion angle for an intramuscular (IM) injection administered into the
deltoid muscle of an adult?
• A. Upper outer quadrant of the buttocks at a 45-degree angle.
• B. Anterior thigh at a 15-degree angle.
• C. Lateral aspect of the upper arm (deltoid) at a 90-degree angle.
• D. Inner forearm at a 90-degree angle.
Correct Answer: C. Lateral aspect of the upper arm (deltoid) at a 90-
degree angle.
,Detailed Rationale: Intramuscular injections require a 90-degree
insertion angle to ensure the medication reaches deep muscle tissue.
The deltoid site is commonly used for adult vaccinations and smaller
volume IM injections.
Question 4
During a standard 12-lead electrocardiogram (ECG), where should the
medical assistant place electrode V4?
• A. Fourth intercostal space at the right sternal border.
• B. Fourth intercostal space at the left midclavicular line.
• C. Fifth intercostal space at the left anterior axillary line.
• D. Fifth intercostal space at the left midclavicular line.
Correct Answer: D. Fifth intercostal space at the left midclavicular line.
Detailed Rationale: V4 placement is standardized at the fifth intercostal
space on the left midclavicular line. V3 is placed midway between V2
and V4, and V5 is at the anterior axillary line.
Question 5
Which type of government-sponsored health insurance program
primarily provides coverage for individuals aged 65 and older, as well as
certain younger individuals with disabilities?
• A. Medicaid
• B. Medicare
• C. TRICARE
• D. Workers' Compensation
, Correct Answer: B. Medicare
Detailed Rationale: Medicare is a federal health insurance program
funded by the federal government specifically for seniors aged 65 and
older, individuals with end-stage renal disease, and certain disabled
individuals. Medicaid is state-administered for low-income populations.
Question 6
What does the medical prefix "nephr-" or "nephro-" specifically refer to
in medical terminology?
• A. Liver
• B. Kidney
• C. Heart
• D. Stomach
Correct Answer: B. Kidney
Detailed Rationale: The combining form "nephr/o" relates to the kidney
(e.g., nephrology, nephritis), whereas "hepat/o" refers to the liver,
"cardi/o" to the heart, and "gastr/o" to the stomach.
Question 7
When performing a routine venipuncture using evacuated tubes, what
is the correct Clinical and Laboratory Standards Institute (CLSI)
recommended order of draw for multiple tubes?
• A. Lavender, Light Blue, Red, Green
• B. Blood Culture bottles / Sterile tubes, Light Blue, Serum
(Red/Tiger top), Green, Lavender, Gray
