226Question

A 13-year-old girl is prescribed a thoracolumbar brace for scoliosis. Which instruction should the nurse give?

  1. Apply lotion and powder to the skin under the brace
  2. Remove the brace whenever it is uncomfortable and put it back on once the discomfort has completely gone away
  3. Stop all physical activity while the brace is in use
  4. Wear a snug cotton shirt under the brace and check the skin for redness at pressure points every day
Show the answer and explanation

Answer: D. Wear a snug cotton shirt under the brace and check the skin for redness at pressure points every day

Topic: Scoliosis brace teaching

A brace is worn for the prescribed number of hours, usually many hours per day. A cotton layer and daily skin checks prevent breakdown, and body image support helps adherence.

Why the others are wrong

  • A – Lotion and powder can macerate or irritate skin under the brace.
  • B – The brace works only when worn for the prescribed hours.
  • C – Most activity is encouraged; the brace is removed for prescribed activities as the provider directs.

  1. Insist that the toddler finish each food item before the next food item is offered.
  2. Ignore the refusals and quietly spoon-feed the toddler so that nutritional intake is maintained.
  3. Offer two acceptable food choices and let the toddler select which one to eat first.
  4. Explain that the parents will be disappointed unless the toddler eats everything on the tray.
Show the answer and explanation

Answer: C. Offer two acceptable food choices and let the toddler select which one to eat first.

Topic: Toddler negativism and autonomy

Toddlers are in Erikson's stage of autonomy versus shame and doubt, and negativism is a normal way of asserting independence. Offering limited, acceptable choices gives a sense of control while keeping the outcome safe.

Why the others are wrong

  • A – Forcing intake turns meals into power struggles and undermines the toddler's need for autonomy.
  • B – Feeding over the child's protest removes all control and usually increases resistance.
  • D – Guilt and shame are not appropriate tools and conflict with building autonomy rather than doubt.

Show the answers and explanation

Answers: A, B and C.

  • A – The child stays dry for about two hours at a time.
  • B – The child can walk to the toilet and sit on it.
  • C – The child can follow simple one-step directions.

Topic: Toilet training readiness

Readiness is physical (dry periods, walking, sitting), cognitive (following simple directions) and emotional (awareness of elimination and willingness to cooperate). Age alone or family disruption does not signal readiness.

Why the others are wrong

  • D – Bowel and bladder control are not neurologically mature at 12 months; readiness usually appears well after the first birthday.
  • E – Major family changes are a reason to wait, because stress often leads to regression.
  • F – Awareness of elimination is a prerequisite; a child without it is not ready.

240Question

A nurse is helping a shy 9-year-old prepare for a physical examination. Which action best respects the child's developmental need for privacy?

  1. Provide a gown, let the child undress alone behind a curtain, and expose only the area examined.
  2. Ask the child to remove all clothing at once so the examination can be finished quickly in the room.
  3. Explain that modesty does not matter because the examiners are all trained health care professionals who see this daily.
  4. Ask a parent to undress the child completely and then wait outside the room until finished.
Show the answer and explanation

Answer: A. Provide a gown, let the child undress alone behind a curtain, and expose only the area examined.

Topic: School-age privacy

School-age children are modest and want control over their bodies. Providing privacy, a gown and limited exposure respects dignity and promotes cooperation.

Why the others are wrong

  • B – Full exposure at once embarrasses a school-age child who is very modest.
  • C – This dismisses a genuine developmental concern and reduces trust.
  • D – Having the child undressed by another person overlooks the child's wish to control exposure and may increase fear.

241Question

A 16-year-old comes to the clinic for a routine visit with a parent. The nurse needs to ask about sexual activity, substance use and mood. Which approach is best?

  1. Interview the adolescent with the parent present so the parent can clarify any answers given.
  2. Explain confidentiality and its limits, then interview the adolescent alone for part of the visit.
  3. Ask the parent to answer the risk-behavior questions to save time during the visit.
  4. Promise that nothing the adolescent says will ever be shared with anyone for any reason.
Show the answer and explanation

Answer: B. Explain confidentiality and its limits, then interview the adolescent alone for part of the visit.

Topic: Adolescent confidentiality

Adolescents need private time to disclose sensitive information. The nurse should describe confidentiality and its limits, which are safety concerns, before the interview.

Why the others are wrong

  • A – Adolescents rarely disclose sensitive information in front of a parent.
  • C – The adolescent is the best source, and the parent may not know the answers.
  • D – Absolute promises cannot be kept because safety concerns, such as suicide risk or abuse, require disclosure.

243Question

A nurse teaches a new mother about reducing the risk of sudden infant death syndrome. Which statement by the mother indicates understanding?

  1. "I will place my baby on her stomach so that she will not choke if she spits up."
  2. "I will put soft blankets and a plush toy in the crib so she stays comfortable."
  3. "I will let her sleep with me on the sofa while we both nap at night."
  4. "I will place my baby on her back to sleep on a firm mattress with only a fitted sheet."
Show the answer and explanation

Answer: D. "I will place my baby on her back to sleep on a firm mattress with only a fitted sheet."

Topic: Safe sleep

Safe sleep means placing the infant supine on a firm, flat surface with no soft objects or loose bedding. Prone sleeping, soft surfaces and sofa sleeping increase risk.

Why the others are wrong

  • A – Prone sleeping raises SIDS risk; healthy infants protect their airway when supine.
  • B – Soft objects and loose bedding increase suffocation and SIDS risk.
  • C – Sofas and armchairs are among the most hazardous sleep surfaces for infants.

244Question

A parent of a 5-month-old asks about starting solid foods. Which statement by the parent indicates a need for further teaching?

  1. "I will begin with iron-fortified infant cereal offered by spoon."
  2. "I will introduce one new food at a time and wait several days before adding another."
  3. "I will mix cereal into the bottle so he sleeps through the night."
  4. "I will wait until he sits with support and no longer pushes food out with his tongue."
Show the answer and explanation

Answer: C. "I will mix cereal into the bottle so he sleeps through the night."

Topic: Introducing solid foods

Cereal in the bottle can cause overfeeding, increases choking and aspiration risk and does not promote sleep. Solids are offered by spoon, around 6 months, when the infant shows readiness cues.

Why the others are wrong

  • A – This is appropriate; iron-fortified cereal supplies a key nutrient at the start of complementary foods.
  • B – This is correct and helps identify food intolerance or allergy.
  • D – These are accurate readiness cues for solid foods.

  3. A toddler who is taking amoxicillin for an ear infection
  4. An infant who was born prematurely at 33 weeks
Show the answer and explanation

Answer: B. A child who developed anaphylaxis after the previous dose of the same vaccine

Topic: Immunization contraindications

A severe allergic reaction to a previous dose or to a vaccine component is a contraindication. Mild illness, antibiotic use and prematurity are not.

Why the others are wrong

  • A – Mild illness is not a contraindication to vaccination.
  • C – Antibiotic therapy does not impair vaccine response.
  • D – Preterm infants are vaccinated by chronological age without delay.

  • C – Set the water heater at or below 120 degrees F (49 degrees C).
  • D – Keep the car seat rear-facing until the child reaches the seat's upper height or weight limit.

Topic: Injury prevention

Toddlers are curious and mobile, so continuous water supervision, locked storage, safe hot-water temperatures and extended rear-facing restraint prevent common serious injuries. Ipecac is not recommended.

Why the others are wrong

  • E – Drowning can occur silently in seconds and in very shallow water; the child must never be left alone.
  • F – Ipecac is no longer recommended; parents should call poison control instead.

247Question

An emergency nurse assesses a 5-month-old who is irritable and vomiting; the parent states the infant fell from a sofa. Which findings raise concern for abusive head trauma?

Select all that apply.

  1. Retinal hemorrhages on eye examination
  2. An explanation that does not fit the injuries or the infant's developmental ability
  3. A bulging fontanelle with irritability and vomiting
  4. A delay in seeking care after the injury
  5. A parent who stays at the bedside and asks about pain relief
  6. Blue-gray pigmented patches over the sacrum present since birth
Show the answers and explanation

Answers: A, B, C and D.

  • A – Retinal hemorrhages on eye examination
  • B – An explanation that does not fit the injuries or the infant's developmental ability
  • C – A bulging fontanelle with irritability and vomiting
  • D – A delay in seeking care after the injury

Topic: Abusive head trauma recognition

Retinal hemorrhages, increased intracranial pressure signs, a history inconsistent with injury and delayed care are red flags for abusive head trauma. Benign skin findings and ordinary parental concern are not.

Why the others are wrong

  • E – A caring, concerned parent is expected and does not suggest abuse.
  • F – These are congenital dermal melanocytosis, a benign finding that should be documented but is not abuse.

248Question

A nurse caring for a 3-year-old notices a patterned burn on the child's buttocks. The caregiver gives an explanation that does not fit the injury. What is the nurse's best action?

  1. Report the suspicion to child protective services as state law requires, without waiting for proof.
  2. Confront the caregiver directly and ask the caregiver to admit to what happened to the child before involving anyone else.
  3. Wait until the radiology report confirms other injuries before deciding whether to report.
  4. Tell the caregiver that a report will be filed only if no convincing explanation is given.
Show the answer and explanation

Answer: A. Report the suspicion to child protective services as state law requires, without waiting for proof.

Topic: Mandatory reporting

Nurses are mandated reporters and must report reasonable suspicion of child abuse to the appropriate agency. Proof is not required and good-faith reports are protected.

Why the others are wrong

  • B – Confronting may endanger the child and the investigation; investigation is not the nurse's role.
  • C – Reasonable suspicion, not confirmation, triggers the duty to report.
  • D – Reporting is mandatory and cannot depend on the caregiver's explanation.

249Question

A nurse assesses a calm, awake healthy 6-month-old at rest. Which vital signs are expected?

  1. Heart rate 70 beats/min and respiratory rate 16 breaths/min
  2. Heart rate 190 beats/min and respiratory rate 70 breaths/min
  3. Heart rate 130 beats/min and respiratory rate 40 breaths/min
  4. Heart rate 60 beats/min and respiratory rate 10 breaths/min
Show the answer and explanation

Answer: C. Heart rate 130 beats/min and respiratory rate 40 breaths/min

Topic: Pediatric vital signs

Infants have faster heart and respiratory rates than adults. Typical awake infant ranges are roughly 100 to 160 beats/min and 30 to 60 breaths/min.

Why the others are wrong

  • A – These values are typical of an adult and would be very low for an infant.
  • B – These rates are too high and suggest distress, fever or illness.
  • D – These values indicate bradycardia and bradypnea in an infant, a pre-arrest sign.

250Question

A nurse prepares a high-alert intravenous medication for a 3-year-old. Which action is most important before administration?

  1. Verify the child's current weight in kilograms and have a second nurse independently check the dose.
  2. Rely on the pharmacy label alone since the pharmacist has already verified the dose before sending it to the unit.
  3. Use the weight recorded on the child's admission six months ago to calculate the dose.
  4. Round the child's weight in pounds to the nearest 10 and convert to kilograms in your head.
Show the answer and explanation

Answer: A. Verify the child's current weight in kilograms and have a second nurse independently check the dose.

Topic: Weight-based dosing safety

Pediatric doses depend on accurate current weight in kilograms. High-alert medications require independent double checks to prevent calculation errors.

Why the others are wrong

  • B – Each nurse is responsible for verifying the dose and the weight; labels do not replace independent checks.
  • C – Dosing requires a current, measured weight because children grow and lose weight quickly.
  • D – Rounding and mental conversions create dosing errors; the weight must be measured and recorded in kilograms.
