The nurse is caring for a client receiving morphine through a Patient Controlled Analgesia Pump (PCA Pump). The nurse knows that important considerations for this treatment include: SELECT ALL THAT APPLY

Choice A reason: This statement is true. This client may have a high tolerance to opioids and require a higher dose for pain control, as tolerance is a condition where the body becomes less responsive to the effects of a drug over time, and needs more of the drug to achieve the same effect. Tolerance can develop from chronic or repeated use of opioids, and can vary from person to person. The nurse should assess the client's pain level, history of opioid use, and response to the medication, and adjust the dose accordingly.

Choice B reason: This statement is false. Clients with a history of opioid abuse should not be denied an opioid analgesic, as opioids are effective and appropriate medications for acute pain management, especially after surgery. The nurse should not discriminate or stigmatize the client based on their history of opioid abuse, but rather provide compassionate and evidence-based care. The nurse should also use a multimodal approach to pain management, which involves using non-opioid analgesics, adjuvant medications, and non-pharmacological interventions, such as ice, heat, massage, or relaxation techniques.

Choice C reason: This statement is false. This client should not wait until their pain is severe, 10/10 before taking a high dose opioid, as this can result in poor pain control, increased stress, and delayed recovery. The nurse should encourage the client to take the medication as prescribed, and to report their pain level regularly. The nurse should also educate the client about the benefits of preventive analgesia, which involves taking the medication before the pain becomes severe, and maintaining a steady blood level of the drug.

Choice D reason: This statement is false. The client's self-report of pain may not be disregarded if they have a history of opioid abuse, as pain is a subjective and personal experience, and the client is the best judge of their own pain. The nurse should not assume that the client is exaggerating, lying, or drug-seeking, but rather respect and validate the client's pain report. The nurse should also use objective indicators of pain, such as vital signs, facial expressions, body movements, and behavioral changes, to support the client's pain assessment.

Choice A reason: This statement is true. Kayexalate is a medication that binds to potassium in the colon and exchanges it for sodium, thereby lowering the blood potassium level. It also has a laxative effect, which helps to eliminate the excess potassium in the stool.

Choice B reason: This statement is false. Kayexalate does not have a diuretic effect, which means it does not increase urine output or fluid loss. Diuretics are medications that act on the kidneys and help to remove excess fluid and sodium from the body.

Choice C reason: This statement is false. Kayexalate does not lower the blood sodium level, but rather increases it. This is because it exchanges potassium for sodium in the colon, which adds more sodium to the bloodstream.

Choice D reason: This statement is false. Kayexalate does not cause diarrhea, but rather a laxative effect, which means it stimulates bowel movements and softens the stool. Diarrhea is a condition where the stool is watery and frequent, and can cause dehydration and electrolyte imbalance.
