Nursing Care of Children ATI
1. The nurse is caring for a child with sickle cell anemia with the following order: Morphine Sulfate 2 mg IV every 24 hours. Morphine Sulfate is available in 10 mg/1mL. How many mL should the nurse administer?
- A. 0.2 mL
- B. 0.5 mL
- C. 1 mL
- D. 2 mL
Correct answer: A
Rationale: To administer 2 mg of Morphine Sulfate when the concentration is 10 mg/mL, the nurse should administer 0.2 mL (2 mg / 10 mg/mL = 0.2 mL). Choice B, 0.5 mL, is incorrect because it is the result of dividing 2 mg by 4 mg/mL instead of 10 mg/mL. Choice C, 1 mL, is incorrect as it would be the result of dividing 2 mg by 2 mg/mL. Choice D, 2 mL, is incorrect as it would be the result of dividing 2 mg by 1 mg/mL.
2. An intravenous line is needed in a school-age child. What medication is an appropriate analgesic for use with this patient?
- A. TAC (tetracaine, epinephrine [Adrenalin], cocaine) 15 minutes before the procedure.
- B. A transdermal fentanyl (Duragesic) patch at the site of venipuncture.
- C. EMLA (eutectic mixture of local anesthetics) immediately before the procedure.
- D. LMX (4% liposomal lidocaine cream) 30 minutes before the procedure.
Correct answer: D
Rationale: LMX is an effective analgesic agent when applied to the skin 30 minutes before a procedure. It eliminates or reduces the pain from most procedures involving skin puncture. TAC provides skin anesthesia about 15 minutes after application to nonintact skin, making it more suitable for wound suturing. Transdermal fentanyl patches are designed for continuous pain control, not rapid pain control needed for a procedure like venipuncture. EMLA, for maximum effectiveness, must be applied approximately 60 minutes before the procedure, making it less suitable for immediate pain relief required for intravenous line placement.
3. A 10-month-old infant is diagnosed with gastroesophageal reflux. An esophageal (pH) probe monitor is ordered. What explanation for the purpose of the esophageal probe should the nurse provide to the parents?
- A. Assist in the passage of formula through the esophagus
- B. Identify the number of reflux episodes that are occurring
- C. Determine the time it takes for the stomach to empty its contents
- D. Monitor the pH within the stomach
Correct answer: B
Rationale: The correct answer is B. The esophageal pH probe is used to identify the frequency and severity of reflux episodes by measuring the pH in the esophagus. Choice A is incorrect because the probe does not assist in the passage of formula through the esophagus. Choice C is incorrect as determining the time it takes for the stomach to empty its contents would require a different procedure. Choice D is incorrect as the esophageal pH probe monitors the pH in the esophagus, not the stomach.
4. What is the first sign of puberty in boys?
- A. Enlargement of testes
- B. Decreased levels of testosterone
- C. Voice deepening
- D. Pubic hair
Correct answer: A
Rationale: The first sign of puberty in boys is typically the enlargement of the testes. This is due to the increase in production of testosterone, which leads to physical changes such as growth of the testes. Choice B, decreased levels of testosterone, is incorrect as puberty is marked by an increase in testosterone levels. Choice C, voice deepening, and choice D, pubic hair growth, usually occur later in the puberty process compared to testicular enlargement, making them incorrect answers.
5. An infant is suspected of having esophageal atresia/tracheoesophageal fistula. While waiting for the pediatrician to see the infant, which action should the nurse take?
- A. Position the infant with the head of the bed slightly elevated
- B. Allow the infant to bond with the mother in her room
- C. Offer the infant breastfeeding instead of formula feeding
- D. Wrap the infant in blankets and place in a crib by the viewing window
Correct answer: A
Rationale: Positioning the infant with the head of the bed elevated helps to prevent aspiration and manage secretions until further treatment can be provided. Choice B is incorrect as the priority is ensuring the infant's safety and health, not immediate bonding. Choice C is incorrect as breastfeeding may worsen the condition. Choice D is incorrect as it does not address the potential risk of aspiration associated with esophageal atresia/tracheoesophageal fistula.
