Start practice test →1. What is the normal resting oral body temperature range for a healthy adult?
- A.Approximately 94.0–96.0°F (34.4–35.6°C)
- B.Approximately 97.0–99.0°F (36.1–37.2°C)✓ Answer
- C.Approximately 92.0–94.0°F (33.3–34.4°C)
- D.Approximately 100.0–102.0°F (37.8–38.9°C)
The accepted average oral temperature is about 98.6°F (37°C), so a normal range spans roughly 97.0–99.0°F; readings above this reflect fever and below reflect hypothermia, which is why option 0 is correct.

2. What is the normal resting pulse (heart rate) range for a healthy adult?
- A.100–120 beats per minute
- B.60–100 beats per minute✓ Answer
- C.20–40 beats per minute
- D.40–60 beats per minute
The normal adult resting heart rate is defined as 60–100 beats per minute; below 60 is bradycardia and above 100 is tachycardia, making 60–100 the correct reference range.

3. What is the normal resting respiratory rate range for a healthy adult?
- A.25–35 breaths per minute
- B.12–20 breaths per minute✓ Answer
- C.4–8 breaths per minute
- D.40–60 breaths per minute
A normal adult breathes 12–20 times per minute at rest; one respiration equals one full inhalation plus exhalation, and this range is the accepted clinical norm for adults.

4. According to current guidelines, a blood pressure reading is considered normal when it is:
- A.Less than 120/80 mmHg✓ Answer
- B.Less than 90/60 mmHg
- C.140/90 mmHg or higher
- D.Exactly 130/85 mmHg
Normal blood pressure is defined as a systolic below 120 mmHg and a diastolic below 80 mmHg; the systolic reflects arterial pressure during heart contraction and the diastolic during relaxation, so less than 120/80 is normal.

5. Which artery is most commonly used to palpate the pulse during a routine adult vital-signs check?
- A.Radial artery at the wrist✓ Answer
- B.Carotid artery in the neck
- C.Femoral artery in the groin
- D.Dorsalis pedis artery on the foot
The radial artery on the thumb side of the wrist is the standard site for routine pulse assessment because it is superficial, easily accessible, and can be palpated without disturbing the patient.

6. What is the key difference between medical asepsis and surgical asepsis?
- A.Both mean exactly the same thing
- B.Medical asepsis reduces the number of microorganisms, while surgical asepsis eliminates all microorganisms and spores✓ Answer
- C.Medical asepsis eliminates all microorganisms, while surgical asepsis only reduces them
- D.Surgical asepsis applies only to injections and medical asepsis only to surgery
Medical asepsis (clean technique) reduces the number and spread of pathogens, whereas surgical asepsis (sterile technique) destroys all microorganisms including spores, which is why it is required for invasive procedures.

7. According to CDC guidance, when should hand hygiene with soap and water be used instead of alcohol-based hand rub?
- A.When hands are visibly soiled or contaminated with blood or body fluids✓ Answer
- B.Only before entering a patient room
- C.Only after removing gloves
- D.Never; alcohol rub is always preferred in all situations
Alcohol-based rubs do not remove visible dirt or reliably kill spores such as C. difficile, so the CDC directs handwashing with soap and water whenever hands are visibly soiled or contaminated with blood or body fluids.

8. The chain of infection includes six links. Which sequence correctly represents them?
- A.Infectious agent → reservoir → portal of exit → mode of transmission → portal of entry → susceptible host✓ Answer
- B.Susceptible host → portal of entry → reservoir → infectious agent → portal of exit → transmission
- C.Reservoir → susceptible host → portal of exit → infectious agent → portal of entry → transmission
- D.Portal of exit → susceptible host → infectious agent → reservoir → portal of entry → transmission
Infection spreads in a fixed order from agent, to reservoir, out a portal of exit, via a mode of transmission, in a portal of entry, to a susceptible host; breaking any link stops the process, so the ordered sequence in option 0 is correct.

9. When donning personal protective equipment (PPE), which item is put on last, and when removing PPE, which is generally removed first?
- A.Gloves are donned first and the gown is removed last
- B.Gloves are donned last and gloves are removed first✓ Answer
- C.The gown is donned last and the mask is removed first
- D.The mask is donned last and gloves are removed last
Gloves cover the hands over the gown cuffs so they are donned last; during removal gloves are the most contaminated item and are taken off first to prevent transferring pathogens to skin, so option 0 is correct.

10. In the standard order of draw for multiple-tube venipuncture, which tube is collected first?
- A.Serum (red top) tubes
- B.Blood culture (sterile) tubes✓ Answer
- C.Sodium fluoride (gray top) tubes
- D.EDTA (lavender/purple top) tubes
Blood culture tubes are drawn first to preserve sterility and prevent contamination by microbes from the skin or other tubes' additives, which is why they lead the order of draw.

11. A lavender/purple-top blood collection tube contains EDTA. What is EDTA's primary function?
- A.It is an anticoagulant that binds calcium to prevent clotting, preserving whole blood for hematology tests✓ Answer
- B.It is a clot activator that speeds serum separation
- C.It has no additive; it is a plain tube
- D.It preserves glucose by inhibiting glycolysis
EDTA chelates (binds) calcium ions that the clotting cascade requires, so blood stays as an anticoagulated whole-blood specimen ideal for CBC and other hematology testing.

12. What is the correct practice for labeling a blood specimen tube?
- A.Leave tubes unlabeled and rely on the order they were drawn
- B.Label all tubes before entering the patient's room to save time
- C.Label the tubes at the lab after all patients are collected
- D.Label the tube at the patient's side immediately after the draw, in the patient's presence✓ Answer
Tubes must be labeled at the bedside immediately after collection while the patient is present so identity can be confirmed, preventing mislabeling errors that could cause a patient to receive results or treatment based on someone else's blood.

13. At what angle is an intradermal (ID) injection, such as a TB skin test, administered?
- A.45 degrees into subcutaneous tissue
- B.60 degrees into the vein
- C.90 degrees into muscle
- D.10–15 degrees, almost parallel to the skin✓ Answer
An intradermal injection deposits fluid into the dermis just under the epidermis, so the needle is inserted at a shallow 10–15 degree angle to form a wheal; a steeper angle would deliver it too deep.

14. A subcutaneous injection is typically administered at what angle into the fatty tissue layer?
- A.15 degrees into the dermis
- B.Always exactly 90 degrees with a long needle
- C.45 degrees (or 90 degrees with a short needle and pinched skin)✓ Answer
- D.10 degrees, nearly flat against the skin
Subcutaneous injections target the fatty layer beneath the dermis and are given at 45 degrees, or at 90 degrees when a short needle is used with the skin pinched up, so option 0 is correct.

15. An intramuscular (IM) injection is administered at what angle, and which is a commonly used site in adults?
- A.90 degrees into the deltoid or vastus lateralis muscle✓ Answer
- B.10 degrees into the anterior wrist
- C.45 degrees into the forearm dermis
- D.15 degrees into the abdomen
IM injections must reach muscle below the subcutaneous fat, so the needle is inserted at a 90-degree angle; the deltoid and vastus lateralis are standard adult sites with adequate muscle mass and away from major nerves.

16. On a standard 12-lead EKG, where are the six precordial (chest) leads V1 through V6 placed?
- A.Three on the neck and three on the abdomen
- B.One on each of the four limbs only
- C.All six on the patient's back
- D.Across the chest wall over the heart, from the right sternal border to the left mid-axillary line✓ Answer
The precordial leads V1–V6 are positioned in sequence across the anterior and left-lateral chest over the heart, giving a horizontal-plane view of cardiac electrical activity, which is why option 0 is correct.

17. On an EKG tracing, what does the QRS complex primarily represent?
- A.The resting baseline between beats
- B.Coronary artery blood flow
- C.Atrial repolarization
- D.Ventricular depolarization (contraction of the ventricles)✓ Answer
The QRS complex records the electrical depolarization that spreads through the ventricles and triggers their contraction; the P wave reflects atrial depolarization and the T wave ventricular repolarization, so QRS = ventricular depolarization.

18. In which position is a patient lying flat on the back, face up, commonly used for abdominal exams?
- A.Fowler's position
- B.Supine position✓ Answer
- C.Prone position
- D.Trendelenburg position
Supine means lying flat on the back with the face upward; it gives access to the anterior body and is standard for abdominal and general examinations, whereas prone is face-down, so option 0 is correct.

19. Fowler's position places the patient in what posture, and for which patients is it especially helpful?
- A.Lying on the left side with the top knee bent, helpful for rectal exams
- B.Sitting up with the head of the table raised about 45–90 degrees, helpful for patients with breathing difficulty✓ Answer
- C.Head lower than the feet, helpful for shock
- D.Lying completely flat on the stomach, helpful for spinal exams
In Fowler's position the head of the table is elevated roughly 45–90 degrees so the patient sits upright, which eases breathing by letting the diaphragm and lungs expand, making it ideal for patients in respiratory distress.

20. Which pulse and temperature sites give a reading closest to the body's true core, and why might a tympanic (ear) or rectal route be chosen?
- A.Rectal and tympanic temperatures approximate core temperature because they are near well-perfused internal tissues shielded from ambient air✓ Answer
- B.The radial pulse measures core temperature directly
- C.Oral temperature is always higher than rectal temperature
- D.Axillary temperature is the most accurate core reading in all patients
Rectal and tympanic sites sit near deep, well-perfused tissue insulated from outside air, so they track core temperature closely; axillary readings run lower and less reliable, which is why core-sensitive situations favor rectal or tympanic routes.
