Which medication order will provide the most consistent control of the patient's chronic pain?

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 the correct choice because the patient’s lung sounds are diminished bilaterally with expiratory wheezes is an example of objective data. Objective data is observable and measurable information that can be verified by the nurse or other health care professionals. The nurse can use a stethoscope to listen to the patient’s lung sounds and document the findings.

Choice B reason: This is an incorrect choice because the patient worries that the insurance company will not pay the hospital bill is an example of subjective data. Subjective data is what the patient tells the nurse about their symptoms, feelings, perceptions, and concerns. The nurse cannot observe or measure the patient’s worry, but can only rely on the patient’s verbal report.

Choice C reason: This is an incorrect choice because the patient wonders if supplemental oxygen at home would be beneficial is an example of subjective data. Subjective data is what the patient tells the nurse about their symptoms, feelings, perceptions, and concerns. The nurse cannot observe or measure the patient’s wonder, but can only rely on the patient’s verbal report.

Choice D reason: This is an incorrect choice because the patient felt less short of breath after receiving a nebulizer treatment is an example of subjective data. Subjective data is what the patient tells the nurse about their symptoms, feelings, perceptions, and concerns. The nurse cannot observe or measure the patient’s feeling, but can only rely on the patient’s verbal report.
