What is the first step in managing a child with anaphylaxis?
- A. Administer antihistamines
- B. Establish IV access
- C. Administer epinephrine
- D. Monitor vital signs
Correct Answer: C
Rationale: The correct answer is to administer epinephrine. Administering epinephrine is the crucial first step in managing anaphylaxis as it helps reverse the severe allergic reaction by constricting blood vessels and relaxing airway muscles, preventing a life-threatening situation. Antihistamines (Choice A) are not the first-line treatment for anaphylaxis and should not delay the administration of epinephrine. Establishing IV access (Choice B) may be necessary but is not the initial step in managing anaphylaxis. Monitoring vital signs (Choice D) is important but should not take precedence over administering epinephrine in the acute management of anaphylaxis.

What is the most effective way to prevent sudden infant death syndrome (SIDS)?
- A. Use a firm mattress
- B. Place the baby on their back to sleep
- C. Keep the room warm
- D. Breastfeed exclusively
Correct Answer: B
Rationale: The correct answer is to place the baby on their back to sleep. This position is the most effective way to prevent sudden infant death syndrome (SIDS) according to research and recommendations from healthcare providers. Choice A, using a firm mattress, is important for infant safety but not as directly related to preventing SIDS. Keeping the room warm, as mentioned in choice C, is not recommended as it may increase the risk of SIDS. While breastfeeding has many benefits, choice D, breastfeeding exclusively is not the most effective method for preventing SIDS.
Melena, the passage of black, tarry stools, suggests bleeding from which source?
- A. The perianal or rectal area
- B. The upper gastrointestinal (GI) tract
- C. The lower GI tract
- D. Hemorrhoids or anal fissures
Correct Answer: B
Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.
Which of the following conditions is characterized by a 'machine-like' murmur in children?
- A. Patent ductus arteriosus
- B. Ventricular septal defect
- C. Atrial septal defect
- D. Coarctation of the aorta
Correct Answer: A
Rationale: The correct answer is A, Patent ductus arteriosus. This condition is characterized by a continuous 'machine-like' murmur due to abnormal blood flow between the aorta and pulmonary artery. Ventricular septal defect (choice B) is characterized by a harsh holosystolic murmur, atrial septal defect (choice C) typically presents with a fixed split S2 and a pulmonary flow murmur, and coarctation of the aorta (choice D) is associated with a systolic murmur in the back and bilateral lower extremities.
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.
The nurse is teaching parents of a child with gastroesophageal reflux (GER) disease about foods that can exacerbate acid reflux. What foods should be included in the teaching session?
- A. Citrus
- B. All of the above
- C. Spicy foods
- D. Peppermint
Correct Answer: B
Rationale: The correct answer is B: All of the above. Citrus, spicy foods, and peppermint are known to exacerbate GER symptoms by increasing acid production or relaxing the lower esophageal sphincter. Therefore, these foods should be avoided by a child with GER disease. Bananas, on the other hand, are generally safe and do not contribute to acid reflux. Choice B is correct because all the mentioned foods can worsen GER symptoms, while bananas are considered safe.
