1. 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.
2. Which signs/symptoms would be considered classical signs of meningeal irritation?
- A. Positive Kernig sign, diarrhea, and headache
- B. Negative Brudzinski sign, positive Kernig sign, and irritability
- C. Positive Brudzinski sign, positive Kernig sign, and photophobia
- D. Negative Kernig sign, vomiting, and fever
Correct answer: C
Rationale: The correct answer is C: Positive Brudzinski sign, positive Kernig sign, and photophobia are considered classical signs of meningeal irritation. The Kernig sign is positive when the leg is extended at the knee and then raised, resulting in pain and resistance. The Brudzinski sign is positive when flexing the neck causes flexion of the hips and knees due to meningeal irritation. Photophobia, or sensitivity to light, is a common symptom due to meningeal inflammation. Choices A, B, and D are incorrect because they do not include the classic signs associated with meningeal irritation.
3. A new mother asks the clinic nurse if she must continue giving her baby nystatin for thrush since the white lesions on his tongue have disappeared. What response by the nurse is most appropriate?
- A. No. When the lesions have disappeared, you may stop the nystatin.
- B. Yes. You should continue it for the full 7 days.
- C. No. Thrush is a self-limiting disorder, and nystatin is given for complete treatment.
- D. Yes. The medication should be refilled for a second week of therapy.
Correct answer: B
Rationale: The correct answer is B because nystatin should be given for the full 7 days even if the lesions are no longer present. Continuing the treatment for the prescribed duration ensures complete eradication of the fungal infection. Choice A is incorrect as stopping the medication prematurely may lead to the reoccurrence of thrush. Choice C is inaccurate as nystatin is not just for comfort but for effective treatment. Choice D is incorrect as refilling the medication for a second week without medical advice may lead to unnecessary prolonged use and potential side effects.
4. A client who had a radical neck dissection returns to the surgical unit with 2 JP drains in the right side of the incision. One JP tube is open and has minimal drainage. Which action should the nurse take to increase drainage into the JP?
- A. Reinforce the incisional dressings and assess behind the neck for drainage.
- B. Place the client in a right lateral side-lying position and elevate the head of the bed.
- C. Irrigate the JP tubing with 1 ml NSS, then close the opening with its tab.
- D. Compress the bulb with the tab open and then reinsert the tab into its opening.
Correct answer: D
Rationale: Compressing the bulb with the tab open creates suction, which helps increase drainage into the JP drain. This action can aid in removing accumulated fluids from the surgical site. Reinforcing the incisional dressings and assessing behind the neck for drainage (Choice A) is not directly related to increasing drainage into the JP. Placing the client in a right lateral side-lying position and elevating the head of the bed (Choice B) may not directly impact drainage into the JP drain. Irrigating the JP tubing with 1 ml NSS and then closing the opening with its tab (Choice C) is unnecessary and could introduce contaminants into the drain.
5. 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.
