Nursing Elites

1. What is the hallmark sign of intussusception?

• A. Mucus-like stools
• B. Currant jelly-like stools
• C. Tarry, black stools
• D. Green, soft stools

Correct answer: B

Rationale: The hallmark sign of intussusception is currant jelly-like stools, which result from the mixture of blood and mucus in the stool due to the sloughing of intestinal mucosa. Mucus-like stools (Choice A) are not typically associated with intussusception. Tarry, black stools (Choice C) are characteristic of gastrointestinal bleeding higher up in the gastrointestinal tract, such as from a peptic ulcer. Green, soft stools (Choice D) are more indicative of rapid transit through the intestines, possibly due to dietary factors or infections such as gastroenteritis.

2. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?

• A. 100 mL/hour.
• B. 125 mL/hour.
• C. 133 mL/hour.
• D. 150 mL/hour.

Correct answer: C

Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.

3. What pathophysiologic process is producing the symptoms of gout in a client with sudden onset of big toe joint pain and swelling?

• A. Deposition of crystals in the synovial space of the joints produces inflammation and irritation.
• B. Degeneration of joint cartilage causing inflammation.
• C. Infection of the joint space leading to inflammation.
• D. Increased synovial fluid causing joint swelling and pain.

Correct answer: A

Rationale: The correct answer is A. Gout is characterized by the deposition of uric acid crystals in the synovial fluid of joints, which triggers inflammation and pain. This process is known as crystal-induced arthritis. Choice B is incorrect as gout does not involve degeneration of joint cartilage. Choice C is incorrect as gout is not caused by an infection of the joint space. Choice D is incorrect as gout does not result from increased synovial fluid but rather from the deposition of uric acid crystals.

4. In planning nursing care for a bedfast client, which factor is most likely to contribute to the development of deep vein thrombosis (DVT) in an immobile client?

• A. Atherosclerotic plaque formation.
• B. Stasis of blood flow.
• C. Endothelial damage.
• D. Atherosclerotic vessel changes.

Correct answer: B

Rationale: The correct answer is B: Stasis of blood flow. Stasis of blood flow in immobile clients increases the risk of DVT, as lack of movement can cause blood to pool and clot. Atherosclerotic plaque formation (choice A) and atherosclerotic vessel changes (choice D) are more related to arterial diseases rather than DVT. Endothelial damage (choice C) can contribute to the development of DVT, but in an immobile client, stasis of blood flow is the most significant factor.

5. 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.
