1. Which healthcare team member is primarily responsible for diagnosing medical
conditions and prescribing treatment?
A. Certified Nursing Assistant (CNA)
B. Medical Assistant
C. Physician
D. Phlebotomist
Complete Solution
Correct Answer: C. Physician
A physician evaluates patients, establishes medical diagnoses, orders diagnostic tests, prescribes
medications, and develops treatment plans. While nurses and allied health professionals
contribute significantly to patient care, the physician has the primary responsibility for diagnosis
and treatment.
2. A patient suddenly becomes unresponsive and has no detectable pulse. What should be
the healthcare worker's immediate action?
A. Give water immediately
B. Begin CPR and activate the emergency response system
C. Wait for family members
D. Take the patient's temperature
Complete Solution
Correct Answer: B. Begin CPR and activate the emergency response system
Cardiac arrest requires immediate intervention. Early CPR maintains blood circulation to vital
organs while emergency medical services are activated. Prompt CPR greatly improves the
chances of survival until advanced care is available.
3. Which infection-control practice is considered the single most effective method of
preventing the spread of disease?
A. Wearing gloves
B. Wearing a face shield
,C. Hand hygiene
D. Wearing shoe covers
Complete Solution
Correct Answer: C. Hand hygiene
Proper hand hygiene removes microorganisms before they can spread between patients,
healthcare workers, and the environment. Hands should be cleaned before and after patient
contact, after removing gloves, and whenever contamination is suspected.
4. Standard Precautions should be used:
A. Only for patients with HIV
B. Only for patients with hepatitis
C. Only for surgical patients
D. For every patient regardless of diagnosis
Complete Solution
Correct Answer: D. For every patient regardless of diagnosis
Standard Precautions assume that all blood and body fluids may contain infectious organisms.
They include hand hygiene, appropriate PPE, respiratory hygiene, safe injection practices, and
proper handling of contaminated equipment.
5. Which patient position is commonly used to improve breathing in a patient experiencing
respiratory distress?
A. Trendelenburg position
B. Supine position
C. Fowler's position
D. Prone position
Complete Solution
Correct Answer: C. Fowler's position
Fowler's position elevates the head of the bed, allowing better lung expansion and easier
breathing. It is frequently used for patients with respiratory disorders such as COPD, pneumonia,
or heart failure.
,6. Which abbreviation should never be used in medical documentation because it may
cause medication errors?
A. mg
B. mL
C. U for units
D. IV
Complete Solution
Correct Answer: C. U for units
The abbreviation "U" may be mistaken for the number "0" or the number "4," leading to
potentially dangerous dosing errors. Best practice is to write the word "units" in full.
7. A patient's blood pressure is recorded as 90/60 mmHg and the patient complains of
dizziness upon standing. This condition most likely indicates:
A. Hypertension
B. Orthostatic hypotension
C. Hyperglycemia
D. Tachycardia
Complete Solution
Correct Answer: B. Orthostatic hypotension
Orthostatic hypotension occurs when blood pressure falls upon standing, reducing blood flow to
the brain and causing dizziness or fainting. Patients should rise slowly and be monitored
carefully to prevent falls.
8. Which patient right requires healthcare providers to explain procedures before obtaining
permission?
A. Confidentiality
B. Informed consent
C. Privacy
D. Beneficence
Complete Solution
Correct Answer: B. Informed consent
, Informed consent requires patients to receive understandable information about the benefits,
risks, alternatives, and purpose of a procedure before voluntarily agreeing to it. Patients must
have the opportunity to ask questions before making their decision.
9. Which laboratory specimen must be collected using strict sterile technique to prevent
contamination?
A. Stool sample
B. Midstream clean-catch urine specimen
C. Hair sample
D. Nail clipping
Complete Solution
Correct Answer: B. Midstream clean-catch urine specimen
A clean-catch urine specimen minimizes contamination from skin bacteria, providing a more
accurate culture for diagnosing urinary tract infections. Patients should clean the genital area
before collecting the midstream portion of urine.
10. Which ethical principle requires healthcare professionals to keep patient information
private?
A. Justice
B. Fidelity
C. Confidentiality
D. Veracity
Complete Solution
Correct Answer: C. Confidentiality
Confidentiality protects patients' personal health information and promotes trust between patients
and healthcare providers. Information should only be shared with authorized individuals directly
involved in the patient's care or as required by law.
11. Which pulse site is commonly used during cardiopulmonary resuscitation (CPR) in
adults to assess circulation?
A. Radial
B. Carotid
C. Brachial
D. Pedal
