Which is the role of the nurse regarding a malfunctioning IV pump?

Choice A reason: This is incorrect. The PCA will not give additional pain medication whenever the button is pushed. The PCA is programmed to deliver a specific dose of pain medication at a specific interval. If the button is pushed before the interval is over, the PCA will not release any medication. This is to prevent overdose and side effects.

Choice B reason: This is incorrect. The PCA will not deliver medication through the IV until the pain is all gone. The PCA is designed to provide pain relief, not pain elimination. The PCA has a limit on how much medication it can deliver in a certain period of time. The patient may still have some pain even after using the PCA.

Choice C reason: This is correct. You or a designated family member are the only one who gets to push the PCA button-nobody else may do so. The PCA is intended to give the patient control over their pain management. The patient should push the button when they feel pain, not when someone else thinks they need it. Allowing others to push the button can lead to under- or over-medication, which can be harmful.

Choice D reason: This is incorrect. Wait until the pain becomes severe before pushing the PCA button is not a good instruction. The PCA is more effective when the patient pushes the button before the pain becomes too intense. Waiting too long can make the pain harder to control and require more medication. The patient should use the PCA as needed to keep the pain at a tolerable level.

Choice A reason: This is an incorrect choice because perceived constipation related to expectation of daily bowel movements is not an appropriate nursing diagnosis for this patient. Perceived constipation is a subjective problem that occurs when the patient's bowel elimination pattern does not meet their personal expectations. The patient may not have any objective signs of constipation, such as hard stools, straining, or abdominal discomfort. This diagnosis is not applicable to this patient, who has objective signs of constipation and a clear cause of the problem.

Choice B reason: This is an incorrect choice because impaired bowel elimination related to abdominal muscle weakness is not an appropriate nursing diagnosis for this patient. Impaired bowel elimination is a problem that occurs when the patient has difficulty in passing stools or has a change in bowel habits. Abdominal muscle weakness is a possible factor that can affect bowel function, but it is not the cause of the problem for this patient. This diagnosis is not applicable to this patient, who has a normal muscle strength and a clear cause of the problem.

Choice C reason: This is an incorrect choice because risk for constipation related to irregular defecation habits is not an appropriate nursing diagnosis for this patient. Risk for constipation is a potential problem that occurs when the patient is vulnerable to developing constipation due to various factors. Irregular defecation habits are a possible factor that can increase the risk of constipation, but they are not the cause of the problem for this patient. This diagnosis is not applicable to this patient, who already has constipation and a clear cause of the problem.

Choice D reason: This is the correct choice because constipation related to side effects of pain medication is an appropriate nursing diagnosis for this patient. Constipation is a problem that occurs when the patient has infrequent, difficult, or incomplete bowel movements. Pain medication, especially opioids, are a common cause of constipation, as they can slow down the gastrointestinal motility and reduce the stool volume and water content. This diagnosis is applicable to this patient, who has objective signs of constipation and a clear cause of the problem..
