1. Which pediatric disorder is associated with a 'boot-shaped' heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Transposition of the great arteries
• C. Coarctation of the aorta
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot is often associated with a 'boot-shaped' heart appearance on a chest x-ray due to the characteristic heart anatomy in this condition. This appearance is caused by the combination of pulmonary stenosis, overriding aorta, ventricular septal defect, and right ventricular hypertrophy. Choice B, Transposition of the great arteries, is incorrect because it presents with a 'egg-on-a-string' appearance on x-ray due to the abnormal position of the aorta and pulmonary artery. Choice C, Coarctation of the aorta, typically presents with rib notching on x-ray. Choice D, Ventricular septal defect, does not produce the 'boot-shaped' heart appearance seen in Tetralogy of Fallot.

2. A child who weighs 10 kg is to receive Motrin 8 mg/kg po q4h prn for pain. The label reads 100 mg/5 mL. How much will you administer?

• A. 4 mL
• B. 2 mL
• C. 5 mL
• D. 3 mL

Correct answer: A

Rationale: To calculate the dosage, multiply the child's weight (10 kg) by the dosage (8 mg/kg) which equals 80 mg. Since the concentration is 100 mg/5 mL, to find out how much to administer, you need to determine how many 5 mL doses are in 80 mg. It will be 80 mg ÷ 100 mg * 5 mL = 4 mL. Therefore, the correct answer is 4 mL. Choice B, 2 mL, is incorrect because it does not account for the correct dosage calculation. Choice C, 5 mL, is incorrect as it does not consider the dosage based on the child's weight. Choice D, 3 mL, is incorrect as it does not reflect the accurate dosage calculation.

3. The nurse is taking vital signs on a group of assigned preschool-aged children. Which assessment finding would indicate the need for further action?

• A. Respiratory rate of 20 breaths per minute
• B. Heart rate of 89 beats per minute
• C. Heart rate of 120 beats per minute
• D. Respiratory rate of 24 breaths per minute

Correct answer: C

Rationale: A heart rate of 120 beats per minute is high for a preschool-aged child and may indicate an underlying issue that requires further assessment. A respiratory rate of 20 breaths per minute (choice A) is within the normal range for preschool children. Similarly, a heart rate of 89 beats per minute (choice B) falls within the expected range. A respiratory rate of 24 breaths per minute (choice D) is slightly elevated but may not be as concerning as a heart rate of 120 beats per minute.

4. A parent calls the hospital nursing hotline and asks, 'My 8-week-old infant cries 8 hours a day, and is hard to console. Is that normal?' What should the nurse's response be to this parent?

• A. No, call your health care provider.
• B. Let me ask you some more questions to see if there are symptoms of colic.
• C. Yes, maybe your infant is just tired.
• D. Yes, infants cry all the time at that age.

Correct answer: B

Rationale: The correct response for the nurse to provide in this situation is to ask more questions to determine if the infant is displaying symptoms of colic. Colic is a common condition in infants that can lead to prolonged crying and fussiness. It is essential to assess for other symptoms before giving advice to the parent. Choices A, C, and D are incorrect because they do not address the possibility of colic or the need for further assessment of the infant's condition.

5. What is the appropriate site to administer an intramuscular (IM) vaccine to a newborn?

• A. The dorsal gluteal muscle
• B. The vastus lateralis muscle
• C. The ventral gluteal muscle
• D. The biceps muscle

Correct answer: B

Rationale: The correct site to administer an intramuscular (IM) vaccine to a newborn is the vastus lateralis muscle. For newborns, the vastus lateralis is preferred over the dorsogluteal site because the dorsogluteal site has been associated with low antibody seroconversion rates, indicating a reduced immune response. The vastus lateralis is also recommended for IM injections in newborns, while the deltoid muscle is preferred for older infants and children. The ventral gluteal muscle and the biceps muscle are not appropriate sites for IM injections. Therefore, choice B is the correct answer.
