WILKINS' CLINICAL PRACTICE OF THE DENTAL
HYGIENIST 14TH EDITION COMPLETE TEST BANK
(CHAPTERS 1-63) – VERIFIED QUESTIONS, ANSWERS,
& RATIONALES
Question 1
,Which of the following professional roles of the dental hygienist involves
analyzing health trends, assessing needs, and implementing clinical services at a
community or population level?
A) Corporate Educator
B) Public Health Administrator
C) Clinician
D) Researcher
VERIFIED ANSWER: B) Public Health Administrator
EXPLANATION: The public health role focuses directly on assessing,
planning, and managing oral health programs for entire communities rather
than treating individual clinical cases or selling industry products.
Question 2
When implementing the Dental Hygiene Process of Care, which specific phase
immediately follows the data collection and clinical assessment stage?
A) Planning
B) Implementation
C) Diagnosis
D) Evaluation
VERIFIED ANSWER: C) Diagnosis
EXPLANATION: The dental hygiene diagnosis acts as the necessary
operational bridge between assessment data collection and creating the
formalized care plan to identify specific patient unmet needs.
,Question 3
Which core ethical value focuses on a dental hygienist’s primary duty to avoid
causing harm, protecting patients from injury or inappropriate interventions?
A) Beneficence
B) Autonomy
C) Nonmaleficence
D) Veracity
VERIFIED ANSWER: C) Nonmaleficence
EXPLANATION: Nonmaleficence means "do no harm." It differs from
beneficence, which describes taking proactive steps to do good and maximize
positive benefits for the patient.
Question 4
Under standard clinical guidelines, what is the recommended exposure time and
temperature for achieving complete sterilization using a gravity displacement
steam autoclave?
A) 15–30 minutes at 250°F (121°C)
B) 3–5 minutes at 270°F (132°C)
C) 60 minutes at 320°F (160°C)
D) 20 minutes at 270°F (132°C)
VERIFIED ANSWER: A) 15–30 minutes at 250°F (121°C)
EXPLANATION: Gravity displacement autoclaves rely on steam pressure
displacing air. This process requires a cycle time of 15 to 30 minutes at a
baseline temperature of 250°F (121°C) to completely kill spores.
, Question 5
Which chemical indicator system should be utilized to definitively verify that a
sterilization unit is successfully killing high-resistance bacterial spores?
A) External chemical indicator tape
B) Internal chemical indicator strip
C) Biological monitor (Spore test)
D) Digital temperature printout
VERIFIED ANSWER: C) Biological monitor (Spore test)
EXPLANATION: Only a biological monitor using highly resistant
Geobacillus stearothermophilus spores verifies that true sterilization has
occurred. Chemical indicators only show that a specific temperature threshold
was hit.
Question 6
During standard clinical patient assessment, which specific artery is most
commonly palpated to determine an adult patient’s resting pulse rate?
A) Carotid artery
B) Brachial artery
C) Radial artery
D) Femoral artery
VERIFIED ANSWER: C) Radial artery
EXPLANATION: The radial artery located on the thumb side of the wrist is
