Nursing Elites

1. A child has been admitted to the pediatric unit with a severe asthma attack. What type of acid-base imbalance should the nurse expect the child to develop?

• A. metabolic alkalosis due to insufficient production of acid metabolites
• B. respiratory alkalosis due to depressed respirations and retention of carbon dioxide
• C. respiratory acidosis due to impaired respirations and increased formation of carbonic acid
• D. metabolic acidosis due to the kidneys' inability to compensate for decreased carbonic acid formation

Correct answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis. This occurs due to impaired respirations, leading to the retention of carbon dioxide and the formation of carbonic acid. Choice A is incorrect as metabolic alkalosis is not expected in this situation. Choice B is incorrect as respiratory alkalosis does not align with the scenario of impaired respirations in severe asthma attacks. Choice D is also incorrect as it describes metabolic acidosis, which is not typically associated with severe asthma attacks.

2. Following delivery of a newborn, the 21-year-old mother is experiencing mild vaginal bleeding. You note that her heart rate has increased from 90 to 120 beats/min and she is diaphoretic. Management should include

• A. Oxygen, uterine massage, and transport
• B. Oxygen, placement on the left side, and transport
• C. Oxygen, treatment for shock, and uterine massage during transport
• D. Oxygen, internal vaginal pads, and treatment for shock during transport

Correct answer: C

Rationale: In this scenario, the 21-year-old mother is showing signs of hemorrhagic shock with increased heart rate, diaphoresis, and vaginal bleeding. The appropriate management includes providing oxygen to support tissue perfusion, treating for shock to restore adequate circulation, and performing uterine massage to help control bleeding during transport. Options A, B, and D do not address the comprehensive management needed for postpartum hemorrhage in this situation.

3. A child with a diagnosis of leukemia is receiving chemotherapy. What is the priority nursing intervention?

• A. Monitoring for signs of infection
• B. Providing nutritional support
• C. Monitoring for signs of bleeding
• D. Monitoring for signs of pain

Correct answer: A

Rationale: The priority nursing intervention for a child with leukemia receiving chemotherapy is monitoring for signs of infection. Chemotherapy can suppress the immune system, putting the child at a higher risk of developing infections. Early detection of signs of infection is crucial to prevent serious complications and initiate timely treatment. Providing nutritional support is important for overall health but is not the priority when the child is at risk of infection. Monitoring for signs of bleeding is essential, but infection surveillance takes precedence due to the immediate threat it poses to the child's health. Monitoring for signs of pain is important for comfort but is not the priority over infection prevention and management.

4. 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.

5. A parent asks the nurse what they can do to help their child who is experiencing night terrors. What should the nurse suggest?

• A. Encourage the child to talk about the dream
• B. Establish a bedtime routine
• C. Allow the child to sleep with the parents
• D. Wake the child during the night

Correct answer: B

Rationale: Establishing a bedtime routine is the most appropriate suggestion for a child experiencing night terrors. Consistent bedtime routines help create a sense of security and predictability, reducing the likelihood of night terrors. Encouraging the child to talk about the dream (Choice A) may not be effective as night terrors occur during non-REM sleep, and the child may not remember the dreams. Allowing the child to sleep with the parents (Choice C) can reinforce dependency and may not address the underlying causes of night terrors. Waking the child during the night (Choice D) can disrupt their sleep cycle and worsen the occurrence of night terrors.
