1. How are infant heart and respiratory rates different from those of an adult?
-
They are faster to compensate for lower volumes of blood and air exchanged with each beat and respiration
-
They are faster to compensate for the larger volume of blood and air exchanged with each beat and respiration
-
They are slower because of the infant's slower metabolism rate
-
They are slower because of the infant's smaller size
Explanation
Explanation
Correct Answer: (A) They are faster to compensate for lower volumes of blood and air exchanged with each beat and respiration
Infants have smaller hearts and lungs, meaning each heartbeat pumps less blood (lower stroke volume) and each breath exchanges less air (lower tidal volume) compared to adults. To meet the body's metabolic demands for oxygen and circulation, infants compensate by having faster heart rates and respiratory rates. This is a normal physiological adaptation to their smaller cardiovascular and pulmonary capacity.
Why Other Options are Incorrect:

This is a normal physiological adaptation to their smaller cardiovascular and pulmonary capacity.
Why Other Options are Incorrect:
- B. They are faster to compensate for the larger volume — This is incorrect; infants exchange smaller, not larger, volumes with each beat and breath.
- C. They are slower because of slower metabolism — Infants actually have a higher metabolic rate than adults, requiring faster, not slower, heart and respiratory rates.
- D. They are slower because of the infant's smaller size — Infant vital rates are faster, not slower, precisely because of their smaller size and lower volume exchange per beat and breath.
2. The nurse determines a parent understands a hospitalized toddler's need for transitional objects when the parent states:
-
"I'd like to get him some toys from the playroom."
-
"I'm going to buy him a big stuffed animal from the gift shop."
-
"This stuffed animal makes him feel secure."
-
"He insisted on bringing this dirty old blanket with him."
Explanation
Explanation
Correct Answer: (D) "He insisted on bringing this dirty old blanket with him."
Transitional objects are items from home — such as a familiar blanket, stuffed animal, or toy — that provide comfort and security to toddlers during stressful experiences like hospitalization. The key feature of a transitional object is that it is a familiar item from the child's home environment. The parent's statement about the child's own blanket from home demonstrates true understanding of the concept, as the familiarity and personal attachment to the object is what provides comfort.

Why Other Options are Incorrect:
- A. "I'd like to get him some toys from the playroom." — Playroom toys are not personal transitional objects; they are shared and unfamiliar items that do not provide the same comfort.
- B. "I'm going to buy him a big stuffed animal from the gift shop." — A newly purchased item lacks the familiarity and emotional attachment that make transitional objects comforting to toddlers.
- C. "This stuffed animal makes him feel secure." — While this shows some understanding of comfort items, it does not specifically demonstrate understanding of transitional objects, which must be familiar items from the child's home environment.
3. A factor that affects the infant's physiological response to medication is:
-
Increased secretion of hydrochloric acid
-
Faster metabolism in the liver
-
Immature kidney function
-
Slower intestinal transit
Explanation
Explanation
Correct Answer: (C) Immature kidney function
Infants have immature renal function, which significantly affects their ability to excrete medications. The kidneys are responsible for filtering and eliminating many drugs and their metabolites from the body. Because glomerular filtration rate and tubular secretion are reduced in infants, drugs remain in the body longer, increasing the risk of toxicity. This is a critical consideration when dosing medications in infants.

Why Other Options are Incorrect:
- A. Increased secretion of hydrochloric acid — Infants actually have decreased gastric acid secretion compared to adults, which affects oral drug absorption rather than overall physiological response.
- B. Faster metabolism in the liver — Infants have immature hepatic enzyme systems, resulting in slower, not faster, liver metabolism of medications.
- D. Slower intestinal transit — Infants actually have increased (faster) gastrointestinal motility, not slower transit, which affects oral drug absorption.
4. The nurse caring for an 8 year old boy is trying to encourage developmental growth. What activity can the nurse provide for the child to encourage his sense of industry?
-
Provide the child with his homework his teacher sent for him
-
Allow the child to choose what time to take his medications
-
Allow the child to help with his dressing change
-
Allow the child to assist with his bath
Explanation
Explanation
Correct Answer: (A) Provide the child with his homework his teacher sent for him
According to Erikson's psychosocial theory, the developmental stage for school-age children (6–12 years) is Industry vs. Inferiority. During this stage, children develop a sense of competence and achievement through productive activities, particularly schoolwork and learning. Providing the child with his homework directly supports his sense of industry by allowing him to continue meaningful, goal-directed work even during hospitalization.

Why Other Options are Incorrect:
- B. Allow the child to choose what time to take his medications — This promotes autonomy and a sense of control, which relates more to Erikson's Autonomy vs. Shame and Doubt stage seen in toddlers.
- C. Allow the child to help with his dressing change — While participation in care can be beneficial, this is more related to fostering independence and cooperation rather than directly addressing the sense of industry through achievement.
- D. Allow the child to assist with his bath — Similar to option C, this encourages self-care and independence but does not specifically address the school-age child's need for productive, skill-building achievement that defines the industry stage.
5. The nurse is caring for a 3 week old infant with a surgical incision. Which of the following pain scales is appropriate for assessing her pain?
-
Qualitative pain scale
-
NIPS
-
Wong Baker Faces scale
-
Numeric pain scale
Explanation
Explanation
Correct Answer: (B) NIPS
The Neonatal Infant Pain Scale (NIPS) is specifically designed for assessing pain in neonates and infants under 1 year of age. It evaluates behavioral and physiological indicators such as facial expression, cry, breathing patterns, arm and leg position, and state of arousal. Since a 3-week-old infant cannot self-report pain, an observational tool like NIPS is the most appropriate choice.

Why Other Options are Incorrect:
- A. Qualitative pain scale — This type of scale requires verbal communication and self-reporting, which a 3-week-old infant is incapable of.
- C. Wong Baker Faces scale — This scale is appropriate for children aged 3 years and older who can identify facial expressions that match their pain level; it is not suitable for neonates.
- D. Numeric pain scale — This scale requires the patient to assign a number to their pain and is used in older children and adults who can understand numerical concepts.
6. Calculate Demerol for a 9 year old weighing 80 pounds (Adult dose Demerol 75 mg)
Explanation
Explanation
Correct Answer: 30 mg
Using Clark's Rule for pediatric dosing:
Demerol for 9 year old (80 lbs, Adult dose 75 mg)
Clark's Rule: (80 ÷ 150) × 75 mg = 40 mg.
Correct Answer: 30 mg
Using Clark's Rule for pediatric dosing:
Demerol for 9 year old (80 lbs, Adult dose 75 mg)
Clark's Rule: (80 ÷ 150) × 75 mg = 40 mg.
7. A child has a continuous intravenous infusion. How frequently should the nurse assess a child's intravenous infusion site?
-
Every three hours
-
Every hour
-
Every four hours
-
Every two hours
Explanation
Explanation:
Correct Answer: (B) Every hour
In pediatric nursing, IV infusion sites in children must be assessed every hour. Children are at higher risk for IV complications such as infiltration, phlebitis, and extravasation due to their smaller, more fragile veins and their inability to communicate discomfort effectively. Hourly assessment allows for early detection and prompt intervention to prevent tissue damage.

Hourly assessment allows for early detection and prompt intervention to prevent tissue damage.
Why Other Options are Incorrect:
- A. Every three hours — This interval is too long for pediatric patients and increases the risk of undetected complications such as infiltration or swelling.
- C. Every four hours — This is the standard assessment interval for adults, not children, who require more frequent monitoring due to their vulnerability.
- D. Every two hours — While more frequent than adult standards, two hours is still not frequent enough for pediatric IV site monitoring per nursing guidelines.
8. A nurse encourages a school-age child to draw a picture after a painful procedure. What is the best rationale for this intervention?
-
She wants to distract the child from thinking about the pain
-
She is encouraging quiet play after pain to stabilize vital signs
-
She is attempting to reestablish rapport
-
She is providing a way for the child to express his feelings
Explanation
Explanation:
Correct Answer: (D) She is providing a way for the child to express his feelings
Drawing is a well-recognized therapeutic tool for school-age children. It allows children to externalize and process emotions they may not yet have the verbal skills to articulate. After a painful procedure, encouraging a child to draw gives them a safe, non-threatening outlet to express fear, anxiety, anger, or discomfort, which supports emotional healing and coping.

Why Other Options are Incorrect:
- A. She wants to distract the child from thinking about the pain — Distraction is a pre-procedure technique. After the procedure, the goal shifts to emotional processing, not distraction from what has already occurred.
- B. She is encouraging quiet play after pain to stabilize vital signs — While quiet activity may have some physiological benefit, this is not the primary or best rationale for encouraging drawing specifically after a painful procedure.
- C. She is attempting to reestablish rapport — While therapeutic activities do support the nurse-patient relationship, the primary purpose of post-procedure drawing is emotional expression, not rapport-building.
9. Which of the following would be considered a normal pulse rate for a 6 month old infant?
-
210
-
198
-
85
-
126
Explanation
Explanation
Correct Answer: (D) 126
The normal heart rate for a 6-month-old infant ranges from 80–160 beats per minute, with an average of approximately 120–130 bpm. A pulse rate of 126 falls well within this normal range. Accurate knowledge of age-appropriate vital sign ranges is essential for nurses to distinguish normal from abnormal findings in pediatric patients.

Correct Answer: (D) 126
The normal heart rate for a 6-month-old infant ranges from 80–160 beats per minute, with an average of approximately 120–130 bpm. A pulse rate of 126 falls well within this normal range. Accurate knowledge of age-appropriate vital sign ranges is essential for nurses to distinguish normal from abnormal findings in pediatric patients.
Why Other Options are Incorrect:
- A. 210 — A pulse rate of 210 is significantly above the normal range for a 6-month-old and would indicate tachycardia requiring immediate assessment and intervention.
- B. 198 — This rate is also far above the normal range and would be considered tachycardia in a 6-month-old infant.
- C. 85 — While 85 is technically within the lower end of the broad infant range, it is below the typical expected range for a 6-month-old and could suggest bradycardia requiring further assessment.
10. The mother of your 2 year patient complains that her son does not play well with other kids. An appropriate response to this statement would be:
-
"Have him play with older children so they can teach him."
-
"Ability to play cooperatively begins to emerge at 3-5 years of age."
-
"Give him a time out if he plays poorly."
-
"You need to model this behavior for your child to understand."
Explanation
Explanation
Correct Answer: (B) "Ability to play cooperatively begins to emerge at 3-5 years of age."
At 2 years of age, toddlers engage in parallel play — playing alongside other children rather than with them. Cooperative play, where children interact, share, and work together, does not begin to develop until approximately 3–5 years of age. Reassuring the mother that this is completely normal developmental behavior for a 2-year-old demonstrates the nurse's knowledge of child development and provides appropriate anticipatory guidance.

Why Other Options are Incorrect:
- A. "Have him play with older children so they can teach him." — This does not address the developmental basis of the behavior and places unrealistic expectations on the child's developmental readiness.
- C. "Give him a time out if he plays poorly." — Punishing a toddler for developmentally normal behavior is inappropriate and could negatively impact the child's self-esteem and development.
- D. "You need to model this behavior for your child to understand." — While modeling is an important parenting strategy, this response does not address or reassure the mother about the normal developmental stage of her 2-year-old.
