Nursing Elites

1. How should a nurse prepare a 15-month-old child diagnosed with hydrocephalus for a computed tomography (CT) scan?

• A. Shaving the child's head
• B. Starting the prescribed IV infusion
• C. Administering the prescribed sedative
• D. Giving the child a simple explanation of the procedure

Correct answer: D

Rationale: Preparing a toddler for a CT scan involves providing a simple explanation of the procedure to help reduce anxiety and fear. Shaving the child's head is unnecessary for a CT scan and may increase distress. Starting an IV infusion or administering sedatives may not be appropriate or necessary for all pediatric patients undergoing CT scans, especially if the child can cooperate without these interventions.

2. A child has been diagnosed with classic hemophilia. A nurse teaches the child’s parents how to administer the plasma component factor VIII through a venous port. It is to be given 3 times a week. What should the nurse tell them about when to administer this therapy?

• A. Whenever a bleed is suspected
• B. In the morning on scheduled days
• C. At bedtime while the child is lying quietly in bed
• D. On a regular schedule at the parents’ convenience

Correct answer: B

Rationale: Administering factor VIII in the morning on scheduled days ensures that there is a consistent level of the plasma component throughout the day, especially when the child is active. This timing helps to maintain adequate levels of factor VIII to prevent bleeding episodes. Choice A is incorrect because administering factor VIII only when a bleed is suspected would not provide the consistent prophylactic coverage needed for children with hemophilia. Choice C is incorrect as bedtime administration may not be practical for ensuring the plasma component is available during the child's active hours. Choice D is incorrect because administering factor VIII on a regular schedule, rather than at specific times of the day, may not optimize its effectiveness in preventing bleeding episodes.

3. Seizures in children most often result from

• A. an abrupt rise in body temperature
• B. an inflammatory process in the brain
• C. a temperature greater than 102°F
• D. a life-threatening infection

Correct answer: A

Rationale: Seizures in children most often result from an abrupt rise in body temperature, leading to febrile seizures. Febrile seizures are common in young children and are typically triggered by a rapid increase in body temperature, often due to infections or other causes. An inflammatory process in the brain (Choice B) is less common as a cause of seizures in children and is usually associated with specific conditions like encephalitis or meningitis. While a temperature greater than 102°F (Choice C) may trigger a febrile seizure, it is the abrupt rise in temperature that is the primary cause. Choice D, a life-threatening infection, is a broad and less specific cause compared to the direct trigger of an abrupt rise in body temperature.

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 receives a note from the school that a student in class has head lice. The parent calls the school nurse to ask how to check for head lice. What instructions should the nurse provide?

• A. Ask the child where it itches.
• B. Check to see if your dog has ear mites.
• C. Look along the scalp line for white dots.
• D. Observe between the fingers for red lines.

Correct answer: C

Rationale: The correct answer is to look along the scalp line for white dots (nits) when checking for head lice. White dots are indicative of head lice infestation. Itching alone, as mentioned in choice A, is not a reliable indicator of head lice. Choice B is irrelevant as it refers to checking for ear mites in a dog, not head lice in a human. Observing between the fingers for red lines, as in choice D, is not a method to check for head lice.
