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 child with type 1 diabetes mellitus is being discharged from the hospital. What is important for the nurse to include in the discharge teaching?

• A. Monitor blood glucose levels once a day
• B. Follow a strict meal plan
• C. Administer insulin only when blood glucose is high
• D. Recognize signs of hypoglycemia

Correct answer: D

Rationale: Recognizing signs of hypoglycemia is crucial for managing type 1 diabetes mellitus and preventing complications.

3. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: The correct answer is A: nondisjunction. Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division leading to an extra copy of chromosome 21. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. Choices B, C, and D are incorrect. X-linked recessive inheritance refers to genetic disorders carried on the X chromosome, genomic imprinting involves gene expression based on parental origin, and autosomal dominant inheritance relates to disorders caused by a dominant gene on one of the non-sex chromosomes. In the case of trisomy 21, the cause is specifically related to the error in chromosome division, making nondisjunction the most appropriate answer.

4. Why should the nurse closely monitor the IV flow rate for a 5-month-old infant with severe diarrhea receiving IV fluids?

• A. Maintaining electrolyte balance
• B. Preventing dehydration
• C. Preventing fluid overload
• D. Avoiding cardiac overload

Correct answer: C

Rationale: In infants, monitoring IV flow rates is essential to prevent fluid overload, not cardiac overload. Excessive fluid administration can lead to complications such as pulmonary edema or congestive heart failure. It is crucial to maintain a balance between providing adequate hydration and avoiding fluid overload to prevent adverse outcomes. Options A, B, and D are incorrect because the primary concern is to prevent complications related to excess fluid rather than focusing on electrolyte balance, dehydration prevention, or avoiding cardiac overload.

5. The nurse is assisting low-income families to access health care. The nurse is aware that, in today's society, this most accurately defines the diversity of a modern family.

• A. A family consists of parents and their offspring living together.
• B. A family is whatever the child and family say it is.
• C. A family is two or more people related or unrelated who are living together.
• D. A family is two or more genetically related persons living together with separate roles.

Correct answer: B

Rationale: In today's diverse society, the concept of family has evolved beyond traditional definitions. Choice B, 'A family is whatever the child and family say it is,' reflects the contemporary understanding that families can take various forms, based on self-identification and individual perspectives. Choice A is too restrictive, as modern families may not solely consist of parents and their offspring living together. Choice C is somewhat inclusive but lacks the recognition of self-identification and diversity within families. Choice D focuses on genetic relation and roles, which may not apply to all modern family structures. Therefore, choice B is the most suitable and inclusive definition of a modern family in today's society.
