Nursing Elites

1. A client with hyperkalemia is being treated in the emergency department. Which medication should the nurse prepare to administer?

• A. Potassium chloride
• B. Calcium gluconate
• C. Magnesium sulfate
• D. Sodium bicarbonate

Correct answer: B

Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.

2. Which statement correctly explains the etiology of Down syndrome?

• A. There is an extra chromosome on the 21st pair.
• B. There is a missing chromosome on the 21st pair.
• C. There are two pairs of the 21st chromosome.
• D. The 21st chromosome pair is missing.

Correct answer: A

Rationale: The correct answer is A: 'There is an extra chromosome on the 21st pair.' Down syndrome is caused by the presence of an extra copy of chromosome 21, known as trisomy 21. This additional genetic material leads to the characteristics associated with Down syndrome. Choices B, C, and D are incorrect because Down syndrome is not due to a missing chromosome or having two pairs of the 21st chromosome; it results from the presence of an extra chromosome on the 21st pair.

3. The cognitive impairment is classified into four levels based on the intelligence quotient (IQ). How is a child with an IQ of 45 classified?

• A. Within the normal low range
• B. Educable
• C. Trainable
• D. Severe

Correct answer: C

Rationale: A child with an IQ of 45 is classified as 'Trainable' in the context of cognitive impairment levels. This category is determined by an IQ range of 35 to 55. Choice A ('Within the normal low range') is incorrect as an IQ of 45 falls within the range associated with the 'Trainable' level, not the 'Normal low range.' Choice B ('Educable') is incorrect because this classification typically corresponds to individuals with slightly higher IQs that allow for academic progress with support. Choice D ('Severe') is incorrect as it does not align with the IQ level of 45, which falls within the 'Trainable' category.

4. What are priority nursing interventions designed to do for a 4-year-old child with cerebral palsy?

• A. Assist with referral to specialized education.
• B. Support the child with independent toileting.
• C. Assist the child to develop effective communication.
• D. Encourage the child to ambulate independently.

Correct answer: C

Rationale: The correct answer is C: 'Assist the child to develop effective communication.' Children with cerebral palsy often face challenges with communication skills. Therefore, priority nursing interventions aim to help them improve their communication abilities. Choice A is incorrect because while education is important, the priority for a child with cerebral palsy is to address immediate needs. Choice B is incorrect as toileting, although important, is not the priority in this case. Choice D is incorrect as ambulation may not be feasible or the most critical concern for a child with cerebral palsy.

5. Which is a long-term complication of cleft lip and palate?

• A. Cognitive impairment
• B. Altered growth and development
• C. Faulty dentition
• D. Physical abilities

Correct answer: C

Rationale: The correct answer is C, 'Faulty dentition.' The older child with cleft lip and palate may experience psychological difficulties due to the cosmetic appearance of the defect, issues with impaired speech, and faulty dentition. This can lead to problems with dental alignment, crowding, missing or malformed teeth, and other dental issues. Choices A, B, and D are incorrect as cognitive impairment, altered growth and development, and physical abilities are not typically considered long-term complications of cleft lip and palate.
