Nursing Elites

1. When describing urticaria, what would an instructor include?

• A. It is a type IV hypersensitivity reaction.
• B. Histamine release leads to vasodilation.
• C. Wheals appear first followed by erythema.
• D. The nonpruritic rash blanches with pressure.

Correct answer: B

Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

2. After a discussion with the health care provider, the parents of an infant with patent ductus arteriosus (PDA) ask the nurse to explain once again what PDA is. How should the nurse respond?

• A. The diameter of the aorta is enlarged.
• B. The wall between the right and left ventricles is open.
• C. It is a narrowing of the entrance to the pulmonary artery.
• D. It is a connection between the pulmonary artery and the aorta.

Correct answer: D

Rationale: The correct answer is D: 'It is a connection between the pulmonary artery and the aorta.' Patent ductus arteriosus (PDA) is an abnormal connection between the pulmonary artery and the aorta, which normally closes after birth. Choices A, B, and C describe different cardiac conditions and do not accurately define PDA. Choice A is incorrect because PDA does not involve the diameter of the aorta being enlarged. Choice B is incorrect because PDA does not involve the wall between the right and left ventricles being open. Choice C is incorrect because PDA is not a narrowing of the entrance to the pulmonary artery.

3. When a child with a diagnosis of asthma is prescribed a peak flow meter, what should the nurse teach the child and parents about using this device?

• A. Use the device before taking medication
• B. Use the device during asthma attacks
• C. Record the best of three attempts
• D. Use the device after eating

Correct answer: C

Rationale: The correct answer is to record the best of three attempts when using a peak flow meter. This method provides a more accurate measure of peak expiratory flow. Choice A is incorrect because using the device before taking medication may not reflect the actual peak flow, as medication can affect lung function. Choice B is incorrect as using the device during asthma attacks may not be feasible or safe, as the focus during an attack should be on managing symptoms rather than measuring peak flow. Choice D is incorrect because using the device after eating may not provide an accurate measurement of peak flow, as digestion can affect lung function temporarily.

4. A nurse on the pediatric unit is observing the developmental skills of several 2-year-old children in the playroom. Which child should the nurse continue to evaluate?

• A. Cannot stand on one foot
• B. Builds a tower of 7 blocks
• C. Uses echolalia when speaking
• D. Colors outside the lines of a picture

Correct answer: C

Rationale: The correct answer is C. Using echolalia, which is the repetition of words or phrases, is not typical for a 2-year-old child and may indicate the need for further evaluation. Choices A, B, and D are all within the expected developmental skills for a 2-year-old. While most 2-year-olds may not be able to stand on one foot, it is not a cause for concern at this age. Building a tower of 7 blocks and coloring outside the lines of a picture are both appropriate for a 2-year-old's developmental skills.

5. The nurse is caring for a 12-year-old boy with idiopathic thrombocytopenia. The nurse is providing discharge instructions about home care and safety recommendations to the boy and his parents. Which response indicates a need for further teaching?

• A. We should avoid aspirin and drugs like ibuprofen.
• B. He should avoid participating in football for safety.
• C. Swimming would be a great activity.
• D. Our son cannot take any antihistamines.

Correct answer: B

Rationale: The correct answer is B. Participation in contact sports like football should be avoided in children with idiopathic thrombocytopenia due to the increased risk of bleeding. Choices A, C, and D are incorrect because avoiding aspirin and drugs like ibuprofen, engaging in activities like swimming, and avoiding antihistamines are all appropriate recommendations for a child with idiopathic thrombocytopenia to prevent bleeding episodes and ensure safety.
