1. 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.

2. A 34-year-old woman, who is 36 weeks pregnant, is having a seizure. After you protect her airway and ensure adequate ventilation, you should transport her

• A. on her left side
• B. in the prone position
• C. in the supine position
• D. in a semi-sitting position

Correct answer: A

Rationale: Transporting a pregnant woman who is having a seizure on her left side is crucial as it helps improve blood flow to the fetus and reduces the risk of further complications. Placing her in the prone position or supine position may compromise blood flow to the fetus and worsen the situation. A semi-sitting position is also not recommended as it may not provide optimal blood flow to the fetus or adequately protect the airway during a seizure.

3. The nurse is assessing a 3-year-old boy whose parents brought him to the clinic when they noticed that the right side of his abdomen was swollen. What finding would suggest this child has a neuroblastoma?

• A. The child has a maculopapular rash on his palms.
• B. The parents report that their son is vomiting and not eating well.
• C. The parents report that their son is irritable and not gaining weight.
• D. Auscultation reveals wheezing with diminished lung sounds.

Correct answer: B

Rationale: Vomiting and poor appetite are common symptoms of neuroblastoma, a malignancy that arises from neural crest cells in the adrenal glands or sympathetic nervous system. This tumor can cause abdominal swelling due to its location and size, leading to symptoms like vomiting and decreased appetite. The presence of a maculopapular rash on the palms (Choice A) is not a typical finding associated with neuroblastoma. Irritability and failure to thrive (Choice C) are nonspecific symptoms that can be seen in various conditions but are not specifically indicative of neuroblastoma. Auscultation revealing wheezing with diminished lung sounds (Choice D) may suggest respiratory conditions rather than neuroblastoma.

4. A child sitting on a chair in a playroom starts to have a tonic-clonic seizure with a clenched jaw. What is the nurse’s best initial action?

• A. Attempt to open the jaw.
• B. Place the child on the floor.
• C. Call out for assistance from staff.
• D. Place a pillow under the child’s head.

Correct answer: B

Rationale: The correct initial action during a tonic-clonic seizure is to place the child on the floor to prevent injury. This action helps protect the child from falling off the chair and provides a safer environment for the seizure to occur. Attempting to open the jaw can cause harm or injury. Calling out for assistance is important but should follow the immediate action of moving the child to the floor. Placing a pillow under the child’s head is not recommended as it may lead to airway obstruction or further injury during the seizure.

5. 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.
