1. The nurse is caring for a newborn with a myelomeningocele. Before surgery, what should the nursing interventions include?
- A. Leaving the lesion uncovered and placing the infant supine
- B. Covering the lesion with a sterile, saline-soaked gauze
- C. Applying lotion to the lesion to keep it moist
- D. Covering the lesion with a dry, sterile gauze
Correct answer: B
Rationale: The correct intervention before surgery for a newborn with a myelomeningocele is to cover the lesion with a sterile, saline-soaked gauze. This helps protect the exposed spinal cord and meninges from infection and damage. Choice A is incorrect because leaving the lesion uncovered can increase the risk of infection. Choice C is incorrect because applying lotion can introduce contaminants to the lesion. Choice D is incorrect because covering the lesion with a dry gauze can lead to adherence of the gauze to the wound, causing trauma upon removal and disrupting the healing process.
2. A client is receiving intravenous potassium chloride for hypokalemia. Which action should the nurse take to prevent complications during the infusion?
- A. Administer the infusion rapidly
- B. Monitor the infusion site for signs of infiltration
- C. Use a syringe pump for the infusion
- D. Flush the IV line with normal saline before starting the infusion
Correct answer: B
Rationale: The correct action to prevent complications during the infusion of potassium chloride is to monitor the infusion site for signs of infiltration. Rapid administration can lead to adverse effects, including cardiac arrhythmias. Using a syringe pump is not typically necessary for this infusion. Flushing the IV line with normal saline is a good practice but not directly related to preventing complications specifically during the infusion of potassium chloride.
3. A client with AIDS has impaired gas exchange from a respiratory infection. Which assessment finding warrants immediate intervention by the nurse?
- A. Elevated temperature
- B. Generalized weakness
- C. Diminished lung sounds
- D. Pain when swallowing
Correct answer: D
Rationale: In a client with AIDS and impaired gas exchange from a respiratory infection, pain when swallowing can indicate esophageal involvement, such as esophagitis or an esophageal infection like candidiasis. These conditions can significantly impact the client's ability to take in nutrition and medications, leading to complications like dehydration and malnutrition. Therefore, immediate intervention is required to address the underlying cause and prevent further complications. Elevated temperature (choice A) may indicate infection but does not directly address the impaired gas exchange. Generalized weakness (choice B) and diminished lung sounds (choice C) are concerning but do not directly relate to the immediate need for intervention in the context of esophageal involvement in a client with impaired gas exchange.
4. A client with liver cirrhosis is at risk for developing hepatic encephalopathy. Which clinical manifestation should the nurse monitor for?
- A. Kussmaul respirations
- B. Asterixis (flapping tremor)
- C. Bradycardia
- D. Hypertension
Correct answer: B
Rationale: Corrected Rationale: Asterixis, also known as a flapping tremor, is a common sign of hepatic encephalopathy, indicating neurological dysfunction due to liver failure. Kussmaul respirations (option A) are associated with metabolic acidosis, which is not a typical manifestation of hepatic encephalopathy. Bradycardia (option C) and hypertension (option D) are not typically associated with hepatic encephalopathy; in fact, hepatic encephalopathy is more commonly associated with alterations in mental status, neuromuscular abnormalities, and changes in behavior.
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.
