Nursing Elites

1. A newborn is diagnosed with metatarsus adductus. The parents ask the nurse how this occurred. Which response by the nurse would be most appropriate?

• A. This condition is due to a genetic defect in the bones.
• B. It's most likely from how the baby was positioned in utero.
• C. They really don't know what causes this condition.
• D. There is probably an underlying deformity of the baby's hip.

Correct answer: B

Rationale: Metatarsus adductus is a condition characterized by the inward turning of the front part of the foot. It is often caused by the baby's position in the womb, leading to the foot adopting this position. Choice A is incorrect because metatarsus adductus is primarily related to positioning in utero rather than a genetic defect. Choice C is incorrect as there is an understanding of the common cause of this condition. Choice D is incorrect because metatarsus adductus specifically refers to a foot deformity, not a hip deformity.

2. What clinical manifestation of tetralogy of Fallot should the nurse expect when caring for children with this diagnosis?

• A. Slow respirations
• B. Clubbing of fingers
• C. Decreased RBC counts
• D. Subcutaneous hemorrhages

Correct answer: B

Rationale: The correct answer is B: Clubbing of fingers. Clubbing of fingers is a common manifestation in children with tetralogy of Fallot due to chronic hypoxia. This condition causes the fingertips and nails to enlarge, creating a bulbous or club-like appearance. Slow respirations (Choice A) are not a typical clinical manifestation of tetralogy of Fallot. Decreased RBC counts (Choice C) may be seen in conditions like anemia but are not specific to tetralogy of Fallot. Subcutaneous hemorrhages (Choice D) are not a characteristic clinical manifestation of tetralogy of Fallot.

3. During a clinical conference with a group of nursing students, the instructor is describing burn classification. 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 are characterized by a leathery, dry appearance with numbness due to nerve damage. Choice A describes characteristics of superficial burns, which are not full-thickness. Choice B describes characteristics of partial-thickness burns with intact blisters, not full-thickness burns. Choice C describes characteristics of partial-thickness burns with blistering and swelling, not full-thickness burns.

4. A healthcare provider is discussing the care of an infant with colic with the parents. What should the healthcare provider explain is the cause of colicky behavior?

• A. Inadequate peristalsis
• B. Paroxysmal abdominal pain
• C. An allergic response to certain proteins in milk
• D. A protective mechanism designed to eliminate foreign proteins

Correct answer: B

Rationale: Colicky behavior in infants is primarily characterized by paroxysmal abdominal pain, resulting in excessive crying and fussiness. The pain episodes are often unpredictable and can be distressing for both the infant and the parents. Inadequate peristalsis (Choice A) refers to weak or ineffective bowel movements and is not the typical cause of colic. While some infants may experience colic due to an allergic response to certain proteins in milk (Choice C), this is not the primary cause of colic behavior in all infants. Choice D, a protective mechanism designed to eliminate foreign proteins, is not a recognized cause of colic. Therefore, the correct explanation for the cause of colicky behavior in infants is paroxysmal abdominal pain.

5. 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.
