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. What is the best position for a client experiencing a nosebleed?

• A. Sitting up and leaning forward
• B. Lying flat with a pillow under the head
• C. Sitting up and leaning back
• D. Lying on the side with the head elevated

Correct answer: A

Rationale: The best position for a client experiencing a nosebleed is sitting up and leaning forward. This position helps prevent blood from flowing down the throat and reduces the risk of aspiration. Choice B is incorrect as lying flat can lead to blood flowing down the throat. Choice C is also incorrect because leaning back may cause blood to flow backward into the throat. Choice D is incorrect as lying on the side with the head elevated is not the optimal position to manage a nosebleed effectively.

3. A client with COPD is receiving home oxygen therapy. Which instruction is most important for the nurse to include in the discharge teaching?

• A. Increase oxygen flow rate during physical activity
• B. Smoke at least 10 feet away from the oxygen source
• C. Use petroleum jelly to prevent nasal dryness
• D. Ensure the oxygen tank is stored in a secure upright position

Correct answer: D

Rationale: The most important instruction for the nurse to include in the discharge teaching for a client with COPD receiving home oxygen therapy is to ensure the oxygen tank is stored in a secure upright position. This is crucial to prevent accidents such as leaks or falls that can lead to serious injury or damage. Choice A is incorrect as increasing the oxygen flow rate during physical activity without a healthcare provider's guidance can be harmful. Choice B is incorrect as smoking near an oxygen source can cause a fire hazard. Choice C is incorrect as petroleum jelly is flammable and should not be used around oxygen due to the risk of combustion.

4. What information should the nurse include in the teaching plan of a client diagnosed with GERD?

• A. Sleep without using pillows
• B. Opt for five small meals throughout the day instead of three full meals with no snacks
• C. Minimize symptoms by wearing loose, comfortable clothing
• D. Engage in low-impact exercises like walking or swimming

Correct answer: C

Rationale: The correct answer is C: 'Minimize symptoms by wearing loose, comfortable clothing.' Wearing loose, comfortable clothing can help reduce pressure on the abdomen, which can alleviate GERD symptoms. Option A is incorrect as sleeping without using pillows is not a recommended practice for managing GERD. Option B is incorrect because it suggests adjusting food intake to five small meals throughout the day instead of three full meals with no snacks, which may not be suitable for everyone with GERD. Option D is incorrect as avoiding participation in any aerobic exercise program is not a standard recommendation for managing GERD; in fact, engaging in low-impact exercises like walking or swimming can be beneficial.

5. What could suddenly occur in a child with acute epiglottitis?

• A. Increased carbon dioxide levels
• B. Airway obstruction
• C. Inability to swallow
• D. Bronchial collapse

Correct answer: B

Rationale: In acute epiglottitis, the infected epiglottis becomes inflamed and can lead to sudden airway obstruction, which is a life-threatening emergency. This can cause difficulty breathing and necessitates immediate intervention to secure the airway. Increased carbon dioxide levels may occur due to inadequate ventilation resulting from airway obstruction, but the primary concern is the obstruction itself, not the carbon dioxide levels. Inability to swallow may be present due to pain and swelling in the throat but is not the immediate life-threatening complication associated with acute epiglottitis. Bronchial collapse is not a typical consequence of acute epiglottitis.
