A nurse is caring for a client who has a sickle cell crisis and is receiving morphine via patient-controlled analgesia (PCA) pump.
Which assessment finding indicates that the PCA pump is effective?
The client reports a pain level of 4 on a scale of 0 to 10.
The client has a respiratory rate of 12 breaths per minute.
The client has a blood pressure of 140/90 mm Hg.
The client has a pulse oximetry reading of 95%.
The Correct Answer is A
The correct answer is choice A. The client reports a pain level of 4 on a scale of 0 to 10. This indicates that the PCA pump is effective in reducing the client’s pain, which is the primary symptom of sickle cell crisis.
Choice B is wrong because a respiratory rate of 12 breaths per minute is normal and does not indicate the effectiveness of the PCA pump.
Choice C is wrong because a blood pressure of 140/90 mm Hg is high and may indicate hypertension, which is a complication of sickle cell disease.
Choice D is wrong because a pulse oximetry reading of 95% is normal and does not indicate the effectiveness of the PCA pump.
Normal ranges for vital signs are:
• Respiratory rate: 12-20 breaths per minute
• Blood pressure: <120/80 mm Hg
• Pulse oximetry: >95%

Correct Answer is B
Explanation
The correct answer is choice B. Administer Percocet every six hours around the clock for two days.
This is because the patient has been receiving a continuous infusion of morphine via a PCA pump, which means that they have a steady level of opioids in their system.
If the PCA pump is discontinued abruptly and the patient is switched to oral analgesics PRN, they may experience withdrawal symptoms and inadequate pain relief.
Therefore, the patient needs to receive a scheduled dose of oral opioids for at least two days to prevent a sudden drop in opioid blood concentration and to maintain adequate analgesia.
After two days, the patient’s pain level and opioid requirement may be reassessed and the oral analgesics may be tapered or given PRN as needed.
Choice A is wrong because a higher dose of Percocet is not necessary if the patient reports satisfactory pain relief with the current PCA settings.The equivalent oral dose of morphine for the patient’s average PCA consumption is about 120 mg per day (20 mg x 6 doses), which is equivalent to about 80 mg of oxycodone per day (1.5 x 120 mg).
The prescribed dose of Percocet is 20 mg of oxycodone per day (5 mg x 4 doses), which is about 25% of the patient’s previous opioid requirement.This reduction is appropriate to account for incomplete cross-tolerance between different opioids.
Choice C is wrong because stopping morphine one hour before giving Percocet will not prevent a gap in analgesia.The half-life of morphine is about 2 to 4 hours, which means that it takes about 10 to 20 hours for morphine to be eliminated from the body.
Therefore, stopping morphine one hour before giving Percocet will not significantly reduce the morphine blood concentration and will not avoid the risk of additive effects or overdose.
Choice D is wrong because giving Percocet only if the patient reports breakthrough pain will not provide adequate pain relief for the patient who has been receiving a continuous infusion of morphine via a PCA pump.
The patient may experience withdrawal symptoms and increased pain sensitivity if the opioid blood concentration drops suddenly.
Therefore, the patient needs to receive a scheduled dose of oral opioids for at least two days to prevent a gap in analgesia and to allow a smooth transition from IV to oral opioids.
Correct Answer is ["A","B","D"]
Explanation
The correct answer is choiceA,B , andD.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can cause gastric irritation and bleeding.Therefore, the nurse should instruct the client to take ibuprofen with food or milk to reduce the risk of stomach ulcers.The nurse should also advise the client to avoid alcohol while taking ibuprofen, as alcohol can increase the risk of gastrointestinal bleeding and liver damage.Additionally, the nurse should tell the client to report any signs of gastrointestinal bleeding, such as black or tarry stools, abdominal pain, or vomiting blood, to the healthcare provider immediately.
ChoiceCis wrong because taking ibuprofen on an empty stomach can increase the risk of gastric irritation and bleeding.
ChoiceEis wrong because taking ibuprofen with antacids can reduce the effectiveness of ibuprofen and interfere with its absorption.Antacids can also cause adverse effects such as diarrhea, constipation, or electrolyte imbalance.
Therefore, the nurse should not recommend taking ibuprofen with antacids.
