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. When caring for a child diagnosed with cystic fibrosis, what is the priority nursing intervention?

• A. Administering pancreatic enzymes
• B. Providing respiratory therapy
• C. Encouraging physical activity
• D. Encouraging frequent handwashing

Correct answer: A

Rationale: The priority nursing intervention when caring for a child with cystic fibrosis is administering pancreatic enzymes. Cystic fibrosis is a genetic disorder that affects the digestive and respiratory systems. Administering pancreatic enzymes is crucial in aiding digestion as patients with cystic fibrosis often have pancreatic insufficiency. While providing respiratory therapy and encouraging physical activity are important aspects of care for individuals with cystic fibrosis, administering pancreatic enzymes takes precedence in addressing the malabsorption issues associated with the condition. Encouraging frequent handwashing is also essential in infection control, but it is not the priority intervention specifically related to managing cystic fibrosis.

3. What behavior does a toddler subjected to prolonged hospitalization with limited parental visits typically exhibit?

• A. Engage in cheerful interactions with staff members
• B. Display indications of sadness throughout the day
• C. Experience excessive crying when parents are not present
• D. Show limited emotional response to the environment

Correct answer: D

Rationale: Toddlers subjected to prolonged hospitalization with limited parental visits usually exhibit a limited emotional response to the environment. This behavior can be a coping mechanism for the child in dealing with the separation from their primary caregivers. The child might not show the same level of engagement or emotional expression as they would if their parents were present. Choices A, B, and C are less likely because the child's emotional response is typically more subdued and withdrawn in such circumstances, rather than being cheerful, consistently sad, or excessively crying.

4. Which best describes a full-thickness (third-degree) burn?

• A. Erythema and pain
• B. Skin showing erythema followed by blister formation
• C. Destruction of all layers of skin evident with extension into subcutaneous tissue
• D. Destruction injury involving underlying structures such as muscle, fascia, and bone

Correct answer: C

Rationale: A full-thickness (third-degree) burn involves the destruction of all layers of skin, including the epidermis, dermis, and extending into the subcutaneous tissue. This type of burn results in significant tissue damage and can appear pale, charred, or leathery. Choice A is incorrect as erythema and pain are more characteristic of superficial burns. Choice B describes a partial-thickness burn where the skin shows erythema followed by blister formation, involving the epidermis and part of the dermis. Choice D is incorrect as it describes a deeper type of injury involving structures beyond the skin layers, such as muscle, fascia, and bone, which is not specific to a full-thickness burn.

5. A child with diabetes insipidus is being treated with vasopressin. The nurse would assess the child closely for signs and symptoms of which condition?

• A. Syndrome of inappropriate antidiuretic hormone (SIADH)
• B. Thyroid storm
• C. Cushing syndrome
• D. Vitamin D toxicity

Correct answer: A

Rationale: The correct answer is A: Syndrome of inappropriate antidiuretic hormone (SIADH). Vasopressin is a medication used to treat diabetes insipidus by increasing water reabsorption in the kidneys. However, an excessive dose of vasopressin can lead to water retention, causing SIADH, which is characterized by dilutional hyponatremia. Choices B, C, and D are incorrect. Thyroid storm is a severe form of hyperthyroidism characterized by increased metabolism and can lead to life-threatening complications. Cushing syndrome results from excess cortisol production and is characterized by weight gain, hypertension, and other features. Vitamin D toxicity occurs due to an overdose of vitamin D, leading to hypercalcemia and symptoms such as nausea, vomiting, and weakness.
