Nursing Elites

1. A nurse is caring for an infant with intractable vomiting. For what complication is it most important for the nurse to assess?

• A. Acidosis
• B. Alkalosis
• C. Hyperkalemia
• D. Hypernatremia

Correct answer: B

Rationale: When an infant experiences intractable vomiting, it can lead to the loss of stomach acids, resulting in metabolic alkalosis. Alkalosis is characterized by elevated blood pH and can lead to serious complications. Assessing for alkalosis is essential in this scenario to monitor and manage the infant's condition. Choices A, C, and D are incorrect because in this context, the primary concern is the metabolic imbalance caused by excessive vomiting, leading to alkalosis rather than acidosis, hyperkalemia, or hypernatremia.

2. A nurse is caring for an infant born with exstrophy of the bladder. What does the nurse determine is the greatest risk for this infant?

• A. Infection
• B. Dehydration
• C. Urinary retention
• D. Intestinal obstruction

Correct answer: A

Rationale: Infection is the greatest risk for an infant with exstrophy of the bladder due to the exposure of the bladder and surrounding tissues. The exposed bladder increases the risk of infection as it lacks the protective covering of the skin. Dehydration (Choice B) may occur but is not the greatest risk compared to infection. Urinary retention (Choice C) is less likely due to the nature of the condition. Intestinal obstruction (Choice D) is not directly associated with exstrophy of the bladder.

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. A nurse is evaluating a 3-year-old child’s developmental progress. The inability to perform which task indicates to the nurse that there is a developmental delay?

• A. Copying a square
• B. Hopping on one foot
• C. Catching a ball reliably
• D. Using a spoon effectively

Correct answer: A

Rationale: The correct answer is A: Copying a square. At 3 years old, children should be able to copy a square as part of their fine motor skill development. The inability to perform this task may indicate a developmental delay in fine motor skills. Choice B, hopping on one foot, typically develops around 4-5 years of age, so it is not a reliable indicator of a delay at 3. Choice C, catching a ball reliably, involves coordination skills that develop later in childhood, making it less relevant for a 3-year-old assessment. Choice D, using a spoon effectively, is more related to self-care and feeding skills rather than fine motor development, so it is not the best indicator of a developmental delay in this context.

5. When teaching the parents of a child with a diagnosis of type 1 diabetes mellitus about insulin administration, what should the nurse emphasize?

• A. Rotate injection sites
• B. Administer insulin before meals
• C. Store insulin in the refrigerator
• D. Administer insulin at bedtime

Correct answer: A

Rationale: The correct answer is to rotate injection sites. This practice helps prevent lipodystrophy, a localized loss of fat tissue that can affect insulin absorption. By rotating sites, the child can avoid developing lumps or indentations in the skin where insulin is repeatedly injected. Administering insulin before meals (choice B) may be necessary for certain types of insulin but is not the priority when teaching about insulin administration. Storing insulin in the refrigerator (choice C) is important for maintaining its potency, but it is not the primary emphasis when teaching about insulin administration. Administering insulin at bedtime (choice D) may be necessary based on the child's insulin regimen but is not the primary consideration for teaching injection techniques and site rotation.
