Nursing Elites

1. A school nurse is teaching parents of school-age children about the importance of immunizations for childhood communicable diseases. What preventable disease may cause the complication of encephalitis?

• A. Varicella
• B. Scarlet fever
• C. Poliomyelitis
• D. Whooping cough

Correct answer: A

Rationale: The correct answer is Varicella (chickenpox), choice A. Varicella can lead to the complication of encephalitis, which is the inflammation of the brain. Scarlet fever (choice B) is caused by Group A Streptococcus bacteria and does not typically lead to encephalitis. Poliomyelitis (choice C) is a viral infection that affects the nervous system but does not directly cause encephalitis. Whooping cough (choice D), also known as pertussis, primarily affects the respiratory system and does not commonly result in encephalitis.

2. 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.

3. During a clinical conference with a group of nursing students, the instructor is describing burn classifications. The instructor determines that the teaching has been successful when the group identifies what as characteristic of full-thickness burns?

• A. Skin that is reddened, dry, and slightly swollen
• B. Skin appearing wet with significant pain
• C. Skin with blistering and swelling
• D. Skin that is leathery and dry with some numbness

Correct answer: D

Rationale: Full-thickness burns, also known as third-degree burns, are characterized by a leathery, dry appearance with numbness due to nerve damage. This type of burn extends through all layers of the skin, affecting nerve endings. Choice A describes characteristics of superficial partial-thickness burns, which involve the epidermis and part of the dermis. Choice B describes characteristics of superficial burns, or first-degree burns, which only affect the epidermis. Choice C describes characteristics of superficial to mid-dermal burns, also known as second-degree burns, which involve the epidermis and part of the dermis but do not extend through all skin layers. Therefore, the correct answer is D.

4. During a physical examination of a 9-month-old baby, the nurse observes a flat, discolored area on the skin. The nurse documents this as a:

• A. Papule.
• B. Macule.
• C. Vesicle.
• D. Scale.

Correct answer: B

Rationale: The correct answer is B: Macule. A macule is a flat, discolored area on the skin that is smaller than 1 cm in diameter. This term is used to describe conditions like freckles or petechiae. Choice A, Papule, refers to a small, solid, raised skin lesion (<0.5 cm) like a pimple. Choice C, Vesicle, describes a small blister filled with clear fluid. Choice D, Scale, refers to flakes or plates of dead skin that may be dry or greasy.

5. The nurse is teaching a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence and beyond.
• B. The process occurs in a cephalocaudal (head-to-toe) pattern.
• C. Myelination decreases the speed of nerve impulses.
• D. Myelination decreases the specificity of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.
