A client taking atorvastatin develops an increased serum creatine phosphokinase (CK) level. The nurse should assess the client for the onset of which problem?

Choice A reason: This is not the first action for the nurse to implement. Determining when the last dose was administered is important to prevent overdose and adverse effects of pain medication, but it is not the most immediate intervention. The nurse should first assess the client's pain level and intensity using a pain scale, such as a numeric or a visual analog scale, to determine the appropriate dose and frequency of pain medication.

Choice B reason: This is not the first action for the nurse to implement. Encouraging the client to use diversional thoughts to manage pain is a nonpharmacological strategy that may help reduce the perception of pain and enhance coping, but it is not the most effective intervention. The nurse should first assess the client's pain level and intensity using a pain scale, and then provide pharmacological and nonpharmacological interventions as needed.

Choice C reason: This is not the first action for the nurse to implement. Reviewing the history for a past use of recreational drugs is relevant to identify the risk of addiction, tolerance, or withdrawal from pain medication, but it is not the most urgent intervention. The nurse should first assess the client's pain level and intensity using a pain scale, and then consider the client's history and preferences when selecting the type and dose of pain medication.

Choice D reason: This is the first action for the nurse to implement. Asking the client to rate the current level of pain using a pain scale is the most appropriate and accurate way to assess the client's pain and its impact on the client's recovery and quality of life. The nurse should use a pain scale that is suitable for the client's age, cognitive ability, and language, and ask the client to rate the pain at rest and with movement. The nurse should also ask the client about the location, quality, duration, and aggravating or relieving factors of the pain. The nurse should use the pain assessment as the basis for planning and implementing pharmacological and nonpharmacological interventions for pain management.

Choice A reason: A yellow skin color may indicate jaundice, which is a sign of liver damage. Acetaminophen can cause liver toxicity, especially in high doses or with chronic use. The nurse should report this finding to the healthcare provider as soon as possible, as it may require further evaluation and treatment.

Choice B reason: Checking the client's capillary glucose level is not relevant to the finding of yellow skin color. Although diabetes can cause skin changes, such as dryness or infections, it does not cause jaundice. The nurse should focus on the potential liver problem rather than the blood sugar level.

Choice C reason: Using a pulse oximeter to assess oxygen saturation is not helpful in this situation. A low oxygen saturation may indicate hypoxia, which can affect various organs, but it does not cause jaundice. The nurse should monitor the client's respiratory status, but it is not the priority action in response to the yellow skin color.

Choice D reason: Advising the client to reduce the medication dose is not appropriate without consulting the healthcare provider. The client may need acetaminophen for pain relief, and reducing the dose may not be enough to prevent liver damage. The nurse should not make any changes to the medication regimen without the provider's order.
