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. What is the priority nursing responsibility when a 3-year-old child in a crib has a clamped jaw and is having a tonic-clonic seizure?

• A. Apply restraints.
• B. Administer oxygen.
• C. Protect the child from self-injury.
• D. Insert a plastic airway in the child’s mouth.

Correct answer: C

Rationale: During a tonic-clonic seizure, the priority nursing responsibility is to protect the child from self-injury. Applying restraints is not recommended during a seizure as it can lead to further harm. Administering oxygen may be necessary after the seizure to support oxygenation, but it is not the priority during the seizure itself. Inserting a plastic airway is also not indicated as the jaw is clamped, and the child should not have anything placed in the mouth during a seizure. Therefore, the correct action is to ensure the child's safety by protecting them from self-injury, preventing harm from uncontrolled movements and potential falls.

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. An additional defect is associated with exstrophy of the bladder. For what anomaly should the nurse assess the infant?

• A. Imperforate anus
• B. Absence of one kidney
• C. Congenital heart disease
• D. Pubic bone malformation

Correct answer: D

Rationale: The correct answer is D, pubic bone malformation. Exstrophy of the bladder is commonly associated with pubic bone malformation because the condition involves a defect in the pelvic region. Choices A, B, and C are incorrect. Imperforate anus, absence of one kidney, and congenital heart disease are not typically associated with exstrophy of the bladder.

5. During the health assessment of a school-age child, on which problem would the nurse focus more attention based on the child's developmental level?

• A. Infections
• B. Poisonings
• C. Risk-taking behaviors
• D. Accidents and injuries

Correct answer: D

Rationale: During the school-age years, children are more physically active and curious, which increases their risk of accidents and injuries. This developmental stage is characterized by increased exploration and engagement in physical activities. While infections and poisonings are important health concerns, school-age children are more likely to be affected by accidents and injuries due to their active nature. Risk-taking behaviors may become more prevalent in adolescence rather than during the school-age period, making it a less likely focus for the nurse during the health assessment of a school-age child.
