Which is the best option for washing the patient’s hair who has just undergone shoulder replacement surgery?

Choice A reason: This is the correct choice because assessment is the step of the nursing process that involves collecting and organizing data about the patient's health status and needs. The nurse who carefully enters a new patient’s medical history and current medication list into the agency’s electronic health record (EHR) is performing an assessment by gathering relevant information from the patient and other sources.

Choice B reason: This is an incorrect choice because implementation is the step of the nursing process that involves carrying out the planned nursing interventions to achieve the patient's goals and outcomes. The nurse who carefully enters a new patient’s medical history and current medication list into the agency’s electronic health record (EHR) is not performing an implementation by executing any actions or treatments for the patient.

Choice C reason: This is an incorrect choice because diagnosis is the step of the nursing process that involves analyzing and interpreting the data to identify the patient's actual or potential health problems. The nurse who carefully enters a new patient’s medical history and current medication list into the agency’s electronic health record (EHR) is not performing a diagnosis by making any judgments or conclusions about the patient's condition.

Choice D reason: This is an incorrect choice because evaluation is the step of the nursing process that involves measuring and comparing the patient's progress and outcomes with the expected goals and outcomes. The nurse who carefully enters a new patient’s medical history and current medication list into the agency’s electronic health record (EHR) is not performing an evaluation by assessing any changes or improvements in the patient's status.

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..
