Content Mastery Series Proctored Assessment
Question 1: A 2-year-old child is brought to the emergency department with a sudden onset
of a harsh, barking cough, stridor, and respiratory distress that is worse at night. Which of the
following nursing interventions is the priority?
A. Administer a bronchodilator via nebulizer
B. Prepare for emergency intubation
C. Provide cool mist humidification and maintain a calm environment
D. Administer an oral corticosteroid
CORRECT ANSWER: C. Provide cool mist humidification and maintain a calm environment
Rationale: The child's symptoms are classic for croup (laryngotracheobronchitis). Cool mist
helps reduce airway edema and inflammation. Keeping the child calm is critical because crying
and agitation increase oxygen demand and can worsen airway obstruction. While steroids and
nebulized epinephrine are treatments, the priority initial nursing intervention is to provide mist
and a calm environment.
Question 2: A nurse is assessing a 6-month-old infant who has been vomiting and has had
diarrhea for two days. Which of the following findings indicates the most severe
dehydration?
A. Sunken anterior fontanelle
B. Dry mucous membranes
C. Decreased urine output
D. Lethargy and delayed capillary refill greater than 3 seconds
CORRECT ANSWER: D. Lethargy and delayed capillary refill greater than 3 seconds
,Rationale: Lethargy and a prolonged capillary refill time (>3 seconds) are signs of severe
dehydration (shock) indicating a critical decrease in intravascular volume. While sunken
fontanelles, dry mucous membranes, and oliguria are signs of dehydration, they are not as
immediately indicative of the impending circulatory collapse seen in severe dehydration.
Question 3: A school-age child with asthma has a peak expiratory flow rate (PEFR) of 60% of
their personal best. According to the traffic light system, this falls into which zone and
warrants which immediate action?
A. Green zone; continue maintenance therapy
B. Yellow zone; administer a rescue bronchodilator and reassess
C. Red zone; administer a rescue bronchodilator and call 911 immediately
D. Yellow zone; administer oral corticosteroids
CORRECT ANSWER: B. Yellow zone; administer a rescue bronchodilator and reassess
Rationale: The asthma traffic light system uses percentages of personal best PEFR: Green (80-
100%) = good control, Yellow (50-79%) = caution indicating an exacerbation requiring a quick-
relief (rescue) bronchodilator, and Red (below 50%) = medical alert requiring emergency action.
60% falls into the Yellow zone.
Question 4: A nurse is caring for a child with acute glomerulonephritis. Which of the following
laboratory findings is consistent with this diagnosis?
A. Elevated serum protein levels
B. Elevated BUN and creatinine
C. Decreased platelet count
D. Positive blood culture
CORRECT ANSWER: B. Elevated BUN and creatinine
Rationale: Acute glomerulonephritis involves inflammation of the glomeruli, leading to
decreased glomerular filtration. This results in elevated waste products in the blood, specifically
BUN and creatinine. Proteinuria and hematuria are also common, but serum protein is often
decreased, not elevated.
Question 5: The mother of a 3-month-old infant with gastroesophageal reflux disease (GERD)
asks the nurse how to reduce the risk of aspiration. Which of the following instructions is
most appropriate?
,A. Place the infant in a supine position immediately after feeding
B. Administer feedings via a bolus over 10 minutes
C. Thicken the formula with rice cereal and keep the infant upright for 30 minutes after feeding
D. Burp the infant only after the feeding is completely finished
CORRECT ANSWER: C. Thicken the formula with rice cereal and keep the infant upright for 30
minutes after feeding
Rationale: Thickening feedings helps decrease the volume of reflux and keeping the infant
upright (at least 30 degrees) for 30-60 minutes after feeding uses gravity to prevent
regurgitation and aspiration. The supine position increases the risk of aspiration. Bolus feeds
increase stomach distension, and burping should be done frequently during the feed.
Question 6: A nurse is preparing to administer a measles, mumps, and rubella (MMR) vaccine
to a 12-month-old. Which of the following is a valid contraindication for this vaccine?
A. Current mild upper respiratory infection
B. Allergy to neomycin
C. History of febrile seizures
D. A temperature of 38°C (100.4°F)
CORRECT ANSWER: B. Allergy to neomycin
Rationale: The MMR vaccine contains neomycin as a preservative. An anaphylactic allergy to
neomycin is a severe contraindication. Minor illnesses with or without a low-grade fever, and a
history of febrile seizures, are not contraindications.
Question 7: An adolescent client is diagnosed with scoliosis and is prescribed a Boston brace.
Which statement by the client indicates a need for further teaching?
A. "I can take the brace off when I shower."
B. "I can take the brace off to sleep at night."
C. "I will wear a t-shirt under the brace to protect my skin."
D. "I can take the brace off for sports, but only if my doctor says it's okay."
CORRECT ANSWER: B. "I can take the brace off to sleep at night."
Rationale: The Boston brace is typically worn for 16-23 hours a day, including during sleep, for
effectiveness. It is removed for bathing/showering and skin care. Wearing a t-shirt prevents skin
breakdown. Taking it off at night significantly reduces its efficacy.
, Question 8: A nurse is assessing a newborn and notes a heart rate of 90 beats per minute,
irregular respirations, a flaccid tone, a reflex response to a grimace, and cyanosis. What is the
one-minute APGAR score?
A. 9
B. 6
C. 5
D. 3
CORRECT ANSWER: D. 3
Rationale: APGAR scoring: Heart rate <100 = 1 point; Irregular respirations = 1 point; Flaccid
tone = 0 points; Reflex grimace = 1 point; Cyanosis = 0 points. Total = 3. This indicates the
newborn is severely depressed and requires immediate resuscitation.
Question 9: A 4-year-old child is hospitalized for Kawasaki disease. Which of the following is
the primary therapeutic goal during the acute phase?
A. Prevent coronary artery aneurysms
B. Reduce joint inflammation
C. Manage hypertension
D. Prevent renal failure
CORRECT ANSWER: A. Prevent coronary artery aneurysms
Rationale: Kawasaki disease is an acute vasculitis that primarily affects the coronary arteries.
The primary goal of treatment (IVIG and high-dose aspirin) during the acute phase is to prevent
cardiac complications, particularly the development of coronary artery aneurysms.
Question 10: Which of the following developmental milestones should a nurse expect a 9-
month-old infant to have achieved?
A. Walks independently
B. Follows a one-step command
C. Pincer grasp
D. Stacks two blocks
CORRECT ANSWER: C. Pincer grasp
Rationale: The pincer grasp (using the thumb and forefinger to pick up objects) typically
develops around 9 months of age. Walking independently occurs around 12-15 months.
Following a one-step command and stacking blocks typically occur around 12-15 months.
