1. A client with cirrhosis is receiving lactulose. What is the desired effect of this medication?
- A. Decrease blood glucose levels
- B. Reduce serum ammonia levels
- C. Increase platelet count
- D. Lower serum bilirubin levels
Correct answer: B
Rationale: The correct answer is B: Reduce serum ammonia levels. Lactulose is used to reduce serum ammonia levels in clients with cirrhosis, helping to prevent hepatic encephalopathy. Lactulose works by acidifying the colon, trapping ammonia for excretion. Decreasing blood glucose levels (choice A) is not the primary effect of lactulose. Increasing platelet count (choice C) and lowering serum bilirubin levels (choice D) are not direct effects of lactulose in the management of cirrhosis.
2. 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.
3. 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.
4. An adolescent female asks the nurse about taking retinoic acid (Accutane). What guidance should be provided by the nurse?
- A. The medication should be used for 10 weeks only.
- B. The medication requires that sexually active females use contraception.
- C. The medication lowers hemoglobin levels very quickly.
- D. The medication has few side effects.
Correct answer: B
Rationale: The correct guidance the nurse should provide is that sexually active females must use contraception while taking Accutane and for 1 month after the 20 weeks it is prescribed. Choice A is incorrect because Accutane is typically taken for a longer duration than 10 weeks. Choice C is incorrect because Accutane does not lower hemoglobin levels quickly. Choice D is incorrect as Accutane is known for having many side effects, including the risk of birth defects.
5. Based on this strip, what is the correct interpretation of this rhythm?
- A. Atrial fibrillation.
- B. Premature atrial fibrillation.
- C. AV block.
- D. Ventricular tachycardia.
Correct answer: A
Rationale: The correct interpretation of the rhythm strip is atrial fibrillation. This arrhythmia is characterized by an irregular heartbeat and the absence of distinct P waves. Choice B, premature atrial fibrillation, is incorrect as there is no indication of premature beats in the strip. Choice C, AV block, is also incorrect as there is no evidence of conduction delays between the atria and ventricles. Choice D, ventricular tachycardia, is not supported by the absence of wide QRS complexes typically seen in this arrhythmia.
