Nursing Elites

1. Congenital heart defects have traditionally been divided into acyanotic or cyanotic defects. Based on the nurse’s knowledge of congenital heart defects, this system in clinical practice is

• A. helpful because it explains the hemodynamics involved
• B. helpful because children with cyanotic defects are easily identified
• C. problematic because cyanosis is rarely present in children
• D. problematic because children with acyanotic heart defects may develop cyanosis

Correct answer: D

Rationale: The classification system of congenital heart defects into acyanotic or cyanotic defects is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation. Cyanosis can occur in some acyanotic defects due to various reasons such as right-to-left shunting or decreased pulmonary blood flow, making the classification based solely on cyanosis misleading. Choice A is incorrect because while the classification may involve hemodynamics, the main issue lies in the potential for acyanotic defects to develop cyanosis. Choice B is incorrect as the ease of identifying children with cyanotic defects does not address the main problem with the classification system. Choice C is also incorrect as the presence of cyanosis is not the only factor determining the classification's validity.

2. The parents of a child who has just been diagnosed with type 1 diabetes ask about exercise. What should the nurse explain about exercise in type 1 diabetes?

• A. Exercise will increase blood glucose levels
• B. Exercise should be restricted
• C. Extra snacks are needed before exercise
• D. Extra insulin is required during exercise

Correct answer: C

Rationale: In type 1 diabetes, extra snacks are needed before exercise to prevent hypoglycemia. It is important to provide additional carbohydrates to maintain blood glucose levels during physical activity. Choices A, B, and D are incorrect. Exercise typically lowers blood glucose levels in individuals with diabetes; however, proper management and adjustments in insulin and food intake are necessary to prevent hypoglycemia. Exercise should not be restricted in individuals with type 1 diabetes but should be planned in coordination with healthcare providers to ensure safety and optimal glucose control. While some individuals may need adjustments in insulin dosages during exercise, the general statement that extra insulin is required during exercise in type 1 diabetes is not accurate.

3. A parent receives a note from the school that a student in class has head lice. The parent calls the school nurse to ask how to check for head lice. What instructions should the nurse provide?

• A. Ask the child where it itches.
• B. Check to see if your dog has ear mites.
• C. Look along the scalp line for white dots.
• D. Observe between the fingers for red lines.

Correct answer: C

Rationale: The correct answer is to look along the scalp line for white dots (nits) when checking for head lice. White dots/nits are the eggs of head lice and are commonly found attached to the hair shaft near the scalp. This method helps identify if head lice are present. Choice A is incorrect as itching alone may not be a definitive sign of head lice; it could be due to other reasons. Choice B is irrelevant as ear mites in dogs are not related to head lice infestation in humans. Choice D is also incorrect as observing between the fingers for red lines is not a method for checking head lice.

4. The nurse is assessing a 4-year-old client. Which finding suggests to the nurse this child may have a genetic disorder?

• A. The inquiry determines the child had feeding problems.
• B. The child weighs 40 lb (18.2 kg) and is 40 in (101.6 cm) in height.
• C. The child has low-set ears with lobe creases.
• D. The child can hop on one foot but cannot skip.

Correct answer: C

Rationale: Low-set ears with lobe creases are often associated with genetic disorders, such as Down syndrome, and can indicate underlying chromosomal abnormalities. This physical characteristic is a common feature seen in various genetic syndromes. The other choices, including feeding problems, weight and height measurements, and motor skills, are not typically specific indicators of genetic disorders in the absence of other associated features.

5. The nurse is assessing a 9-year-old girl with a history of tuberculosis at age 6 years. She has been losing weight and has no appetite. The nurse suspects Addison disease based on which assessment findings?

• A. Arrested height and increased weight
• B. Thin, fragile skin and multiple bruises
• C. Hyperpigmentation and hypotension
• D. Blurred vision and enuresis

Correct answer: C

Rationale: The correct answer is C: Hyperpigmentation and hypotension. These findings are classic signs of Addison disease, caused by adrenal insufficiency. Hyperpigmentation results from increased ACTH stimulating melanin production, and hypotension occurs due to mineralocorticoid deficiency. Choices A, B, and D are incorrect. Arrested height and increased weight are not typical of Addison disease. Thin, fragile skin and multiple bruises are seen in conditions like Cushing's syndrome, not Addison disease. Blurred vision and enuresis are not characteristic symptoms of Addison disease.
