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. A 2-week-old infant is admitted with a tentative diagnosis of a ventricular septal defect. The parents report that their baby has had difficulty feeding since coming home after birth. What should the nurse consider before responding?

• A. Feeding problems are common in neonates.
• B. Inadequate sucking is not significant in the absence of cyanosis.
• C. Ineffective sucking and swallowing may be early indications of a heart defect.
• D. Many neonates retain mucus, which may interfere with feeding for several weeks.

Correct answer: C

Rationale: In this scenario, the nurse should consider that ineffective sucking and swallowing in a 2-week-old infant could be early signs of a heart defect such as a ventricular septal defect. This is crucial information as it can guide further assessment and management. Choice A is incorrect because while feeding problems can be common in neonates, in this case, the specific context of a suspected heart defect should be prioritized. Choice B is incorrect as inadequate sucking can indeed be significant, especially when considering potential underlying heart issues, regardless of the presence of cyanosis. Choice D is incorrect as while mucus retention can affect feeding, in this case, the focus should be on the possibility of a heart defect rather than a temporary issue like mucus interference.

3. When compensating for increased physical activity, what should the nurse teach a child with type 1 diabetes to do?

• A. Eat more food when planning to exercise more than usual.
• B. Take oral, not injectable insulin, on days of heavy exercise.
• C. Take insulin in the morning when extra exercise is anticipated.
• D. Eat foods that contain sugar to compensate for the extra exercise.

Correct answer: A

Rationale: The correct answer is to 'Eat more food when planning to exercise more than usual.' Increased physical activity requires more energy, so additional food intake is necessary to prevent hypoglycemia. Choice B is incorrect because the method of insulin administration should not be altered based on physical activity. Choice C is incorrect as insulin timing should be consistent rather than based on anticipated exercise. Choice D is incorrect since relying on foods with sugar can lead to unstable blood sugar levels, which is not ideal for managing diabetes during exercise.

4. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?

• A. Chest X-ray
• B. Sweat chloride test
• C. Pulmonary function test
• D. Sputum culture

Correct answer: B

Rationale: The correct answer is the sweat chloride test. This test is crucial in diagnosing cystic fibrosis as it measures the amount of chloride in sweat, which is typically elevated in individuals with cystic fibrosis. A chest X-ray (Choice A) may show characteristic findings like hyperinflation or bronchiectasis, but it is not a definitive diagnostic test for cystic fibrosis. Pulmonary function tests (Choice C) may help assess lung function but are not specific for cystic fibrosis. Sputum culture (Choice D) may be used to identify specific pathogens causing respiratory infections but is not a primary diagnostic test for cystic fibrosis.

5. A nurse is teaching a class about immunizations to members of a grammar school’s Parent-Teachers Association. Which childhood disease is the nurse discussing when explaining that it is a viral disease that starts with malaise and a highly pruritic rash that begins on the abdomen, spreads to the face and proximal extremities, and can result in grave complications?

• A. Rubella
• B. Rubeola
• C. Chickenpox
• D. Scarlet fever

Correct answer: C

Rationale: The correct answer is C, Chickenpox (varicella). Chickenpox is a viral disease characterized by a highly pruritic rash that typically starts on the abdomen and then spreads to other parts of the body, including the face and proximal extremities. It can lead to complications such as pneumonia and encephalitis. Rubella (German measles) presents with a mild rash and swollen lymph nodes; Rubeola (measles) also presents with a rash but starts on the face before spreading downwards; Scarlet fever is caused by Group A Streptococcus bacteria and is characterized by a rash, fever, and sore throat.
