Nursing Elites

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. When assessing a child with suspected nephrotic syndrome, what clinical manifestation is the nurse likely to observe?

• A. Jaundice
• B. Edema
• C. Hypertension
• D. Polyuria

Correct answer: B

Rationale: Edema is a hallmark clinical manifestation of nephrotic syndrome. In nephrotic syndrome, there is increased glomerular permeability leading to the loss of proteins, particularly albumin, in the urine. This results in decreased oncotic pressure, leading to fluid shifting into the interstitial spaces and causing edema. Jaundice (Choice A) is not a typical clinical manifestation of nephrotic syndrome. Hypertension (Choice C) is more commonly associated with conditions like glomerulonephritis. Polyuria (Choice D) is not a primary symptom of nephrotic syndrome; instead, patients may have reduced urine output due to fluid retention from edema.

3. When discussing the side effects of the Haemophilus influenzae (Hib) vaccine with parents, which sign should the nurse mention for an infant receiving the vaccine?

• A. Lethargy
• B. Urticaria
• C. Generalized rash
• D. Low-grade fever

Correct answer: D

Rationale: The correct answer is 'Low-grade fever.' A low-grade fever is a typical, mild side effect that can occur after the Hib vaccine is administered. It is a sign that the body's immune system is responding to the vaccine and is generally not a cause for concern. Lethargy, urticaria, and generalized rash are not commonly associated side effects of the Hib vaccine. Lethargy may be a sign of other issues, while urticaria and generalized rash are more indicative of allergic reactions rather than typical responses to the Hib vaccine.

4. What is the priority nursing intervention for a child with a diagnosis of acute lymphoblastic leukemia (ALL) receiving chemotherapy?

• A. Preventing infection
• B. Administering chemotherapy
• C. Providing nutritional support
• D. Monitoring fluid intake

Correct answer: A

Rationale: The correct answer is A: Preventing infection. When caring for a child with acute lymphoblastic leukemia (ALL) undergoing chemotherapy, the top priority is to prevent infection. Chemotherapy suppresses the immune system, making the child more susceptible to infections. By implementing infection control measures such as hand hygiene, aseptic techniques, and environmental cleanliness, the nurse can help protect the child from potentially life-threatening infections. Administering chemotherapy (choice B) is important but not the priority over preventing infection. Providing nutritional support (choice C) and monitoring fluid intake (choice D) are essential aspects of care but take a back seat to preventing infection in this scenario.

5. The parents of a 2-year-old child tell the nurse that they are having difficulty disciplining their child. What is the nurse’s most appropriate response?

• A. “This is a challenging age for your child right now.”
• B. “Could you elaborate on your challenges? I’m not clear on what you mean.”
• C. “It’s important to be consistent with toddlers when they need discipline.”
• D. “I understand your concern. This phase is often referred to as the 'terrible twos'.”

Correct answer: C

Rationale: The most appropriate response for the nurse is to emphasize the importance of consistency in discipline when dealing with toddlers. Toddlers are at a stage where they are exploring boundaries and learning what behaviors are acceptable. By being consistent, parents can help reinforce these boundaries and teach appropriate behaviors effectively. Choices A, B, and D do not provide specific guidance on how to address the discipline issue effectively. While acknowledging the challenges of this age (Choice A) and empathizing with the parents (Choice D) are important, the key point in this scenario is to highlight the significance of consistency in discipline (Choice C).
