Advanced Pathophysiology (NRMS 5190) — Exam 2
Question & Answers/ Rationales.
knee. According to pediatric health assessment principles, how should the examiner sequence the
physical exam?
(A) Avoid examining the left knee and refer immediately to orthopedics
(B) Perform a complete head-to-toe examination in strict chronological order
(C) Examine the left knee first before the child becomes fatigued
(D) Examine the left knee last at the end of the examination
Correct Answer: (D) Examine the left knee last at the end of the examination
Rationale: According to the Health Assessment Unit 2 Study Guide, if a child reports pain in one specific area,
the clinician should examine that painful area last. Furthermore, potential distressing maneuvers should be
saved for the end of the exam.
Question 2. Which statement accurately reflects one of the four foundational principles of child
development?
(A) Child development proceeds along a predictable pathway
(B) The child's developmental level should not alter H&P examination techniques
(C) Disease and environmental factors do not alter developmental velocity
(D) The range of normal development is narrow and strictly uniform across children
Correct Answer: (A) Child development proceeds along a predictable pathway
Rationale: The study notes state the Four Principles of Child Development: 1. Child development proceeds along
a predictable pathway; 2. The range of normal development is wide; 3. Physical, social, environmental factors
and disease affect development; 4. Developmental level affects how the H&P exam is conducted.
Question 3. An 8-month-old infant is evaluated and found to have a Developmental Age of 5 months. What
is the calculated Developmental Quotient (DQ) and its clinical interpretation?
(A) DQ = 62.5; Delayed development requiring further evaluation
(B) DQ = 62.5; Normal development
(C) DQ = 80; Possibly delayed requiring follow-up
(D) DQ = 160; Advanced development
Correct Answer: (A) DQ = 62.5; Delayed development requiring further evaluation
Rationale: Developmental Quotient (DQ) = (Developmental Age / Chronological Age) x 100. Here, () x 100
= 62.5. A DQ < 70 is classified as delayed, DQ 70-85 is possibly delayed, and DQ > 85 is normal.
,Question 4. In observing motor development in a newborn, which direction best describes the
progression of neurological and physical development?
(A) Random and uncoordinated motor acquisition
(B) Distal to proximal (foot control before hip stability)
(C) Centrally to peripherally (head control before trunk control; control of arms/legs before hands/fingers)
(D) Peripherally to centrally (finger fine motor skills develop before head control)
Correct Answer: (C) Centrally to peripherally (head control before trunk control; control of arms/legs before
hands/fingers)
Rationale: Neurological and physical development in infants progresses centrally to peripherally. Examples
include achieving head control before trunk control, and controlling arms and legs before hands and fingers.
Question 5. An infant is born weighing 7 lbs (3.2 kg) and measuring 20 inches in length. According to
normal infant growth parameters, what expected weight and height milestones should be documented at
12 months?
(A) Weight quadruples (28 lbs) and height increases by 25%
(B) Weight increases by 50% and length triples
(C) Weight doubles (14 lbs) and height doubles (40 inches)
(D) Weight triples (21 lbs) and height increases by 50% (30 inches)
Correct Answer: (D) Weight triples (21 lbs) and height increases by 50% (30 inches)
Rationale: Physical growth parameters state that an infant's birth weight doubles by 6 months and triples by 1
year. Height/length increases by 50% from birth by 1 year of age.
Question 6. During a routine health maintenance exam of a 4-month-old infant, which approach minimizes
infant distress and facilitates a successful physical assessment?
(A) Undress the infant completely including the diaper at the beginning of the assessment
(B) Perform a rigid head-to-toe examination while the infant is supine on the cold exam table
(C) Perform much of the exam while the infant sits in the parent's lap and save distressing ear/mouth
exams for last
(D) Examine the mouth and pharynx first while the infant is calm
Correct Answer: (C) Perform much of the exam while the infant sits in the parent's lap and save distressing
ear/mouth exams for last
Rationale: General guidelines for examining infants recommend approaching gradually, performing much of
the exam in the parent's lap, speaking softly, leaving the diaper in place until examining genitals/hips, and
saving potentially distressing parts (mouth and ears) for last.
Question 7. In measuring growth parameters for a 14-month-old child, which technique and criteria
warrant detailed clinical evaluation?
(A) Measuring BMI starting at birth; length measured standing against a wall
(B) Measuring standing height with a stadiometer; growth parameters between the 25th and 75th
percentiles
(C) Measuring supine length on a measuring board; growth parameters beyond 2 standard deviations
or <5th/>95th percentile
(D) Measuring head circumference until age 5 years; weight measured with clothing
Correct Answer: (C) Measuring supine length on a measuring board; growth parameters beyond 2 standard
deviations or <5th/>95th percentile
Rationale: For infants younger than 2 years, length is measured supine on a measuring board or tray. Variations
beyond 2 standard deviations for age, or <5th percentile and >95th percentile on growth charts, are
indications for more detailed evaluation.
, Question 8. A 2-month-old infant is brought to the clinic for a well-child visit. Which vital sign
measurement is considered abnormal and defines tachypnea in this age group?
(A) A sleeping respiratory rate of 65 breaths per minute
(B) A rectal temperature of 98.6°F (37.0°C)
(C) A resting heart rate of 130 beats per minute
(D) A sleeping respiratory rate of 45 breaths per minute
Correct Answer: (A) A sleeping respiratory rate of 65 breaths per minute
Rationale: In infants from birth to 2 months of age, tachypnea is defined as a respiratory rate > 60 breaths per
minute. Respiratory rate should be observed for a full 60 seconds, and the sleeping respiratory rate is most
reliable.
Question 9. According to pediatric vital sign standards, what is the normal average heart rate and range
for an infant aged 1 to 6 months?
(A) Average 140 bpm (Range: 90–165 bpm)
(B) Average 130 bpm (Range: 80–175 bpm)
(C) Average 115 bpm (Range: 90–170 bpm)
(D) Average 85 bpm (Range: 55–115 bpm)
Correct Answer: (B) Average 130 bpm (Range: 80–175 bpm)
Rationale: Age-specific average heart rates from the study guide: Birth–1 month: Avg 140 (90–165); 1–6
months: Avg 130 (80–175); 6–12 months: Avg 115 (90–170).
Question 10. A clinician evaluates a 6-week-old infant who presents with a rectal temperature of 38.2°C
(100.8°F). What is the significance of this finding in an infant under 3 months?
(A) Rectal temperatures are inaccurate in infants under 6 months
(B) This is a normal diurnal fluctuation and requires no follow-up
(C) A rectal temperature >38.0°C in an infant <3 months is defined as a fever requiring urgent clinical
evaluation
(D) Fever in infants is only significant if the rectal temperature exceeds 40.0°C
Correct Answer: (C) A rectal temperature >38.0°C in an infant <3 months is defined as a fever requiring urgent
clinical evaluation
Rationale: A temperature > 38.0°C (100.4°F) in an infant less than 3 months of age is considered a fever and
represents a medical red flag requiring prompt evaluation for serious bacterial infection.
Question 11. During facial inspection of an infant, the clinician notes upslanting palpebral fissures and
small white elevated spots arranged in a ring on the iris. What condition and ocular finding are present?
(A) Turner syndrome; Horner syndrome
(B) Down syndrome; Brushfield spots
(C) Noonan syndrome; Epicanthic folds
(D) Fetal alcohol syndrome; Strabismus
Correct Answer: (B) Down syndrome; Brushfield spots
Rationale: Upslanting palpebral fissures and Brushfield spots (little white elevated spots on the iris surface arranged
in a ring concentric with the pupil) are characteristic findings seen in Down syndrome.
