Nursing Elites

1. 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.

2. A male client with muscular dystrophy fell in his home and is admitted with a right hip fracture. His right foot is cool, with palpable pedal pulses. Lungs are coarse with diminished bibasilar breath sounds. Vital signs are temperature 101 degrees F, heart rate 128 beats/minute, respirations 28 breaths/minute, and blood pressure 122/82. Which intervention is most important for the nurse to implement first?

• A. Obtain oxygen saturation level.
• B. Encourage incentive spirometry.
• C. Assess lower extremity circulation
• D. Administer PRN oral antipyretic.

Correct answer: D

Rationale: Administering an antipyretic is the most important intervention. The client presents with an elevated temperature, tachycardia, and tachypnea, indicating a fever. Lowering the temperature with an antipyretic is crucial to prevent complications like dehydration, altered mental status, and increased oxygen demand. While assessing lower extremity circulation and oxygen saturation are important, addressing the elevated temperature takes priority in this scenario. Incentive spirometry may be beneficial but is not the priority compared to managing the fever.

3. The nurse is assessing a client who reports sudden onset of severe eye pain and blurred vision. What is the priority nursing intervention?

• A. Administer prescribed pain medication.
• B. Notify the healthcare provider immediately.
• C. Place an eye patch over the affected eye.
• D. Prepare the client for a CT scan.

Correct answer: B

Rationale: The correct answer is to notify the healthcare provider immediately (Choice B). Sudden severe eye pain and blurred vision can indicate acute angle-closure glaucoma, which is a medical emergency requiring prompt evaluation and treatment to prevent vision loss. Administering pain medication (Choice A) may provide temporary relief but does not address the underlying cause. Placing an eye patch (Choice C) may not be appropriate without knowing the exact cause of the symptoms. Preparing for a CT scan (Choice D) is not the immediate priority in this situation where urgent medical attention is needed.

4. What assessment findings should lead the nurse to suspect Down syndrome in a newborn?

• A. Hypertonia and dark skin
• B. Low-set ears and a simian crease
• C. Inner epicanthal folds and a high, domed forehead
• D. Long, thin fingers and excessive hair

Correct answer: B

Rationale: The correct answer is B: 'Low-set ears and a simian crease.' These are key physical characteristics commonly seen in newborns with Down syndrome. Low-set ears, along with a simian crease (a single palmar crease), are indicative of Down syndrome. Choices A, C, and D are incorrect because hypertonia, dark skin, inner epicanthal folds, a high, domed forehead, long, thin fingers, and excessive hair are not specific features associated with Down syndrome in newborns. Therefore, the presence of low-set ears and a simian crease should raise suspicion for Down syndrome and prompt further evaluation.

5. Which individual has the highest risk for developing skin cancer?

• A. A 16-year-old dark-skinned female who tans in tanning beds once a week.
• B. A 65-year-old fair-skinned male who is a construction worker
• C. A 25-year-old dark-skinned male whose mother had skin cancer.
• D. A 70-year-old fair-skinned female who works as a secretary.

Correct answer: B

Rationale: The correct answer is B, a 65-year-old fair-skinned male who is a construction worker. Fair-skinned individuals are at higher risk of developing skin cancer due to prolonged sun exposure. Construction workers are often exposed to the sun for long periods, further increasing the risk. Choices A, C, and D are less likely to develop skin cancer compared to choice B due to factors such as age, frequency of tanning bed use, and occupation.
