A nurse is unfamiliar with a medication they are preparing to administer to a client. Prior to administering the medication, the nurse should refer to which of the following resources?

A. Remove the tape by pulling from the center of the dressing. Tape should be removed by pulling toward the wound rather than from the center to avoid skin trauma and unnecessary disruption to the healing tissue. Pulling from the center can increase discomfort and damage surrounding skin.
B. Clean the wound from the center to the outer edges. Cleaning from the center outward prevents the introduction of microorganisms from the surrounding skin into the wound, reducing the risk of further infection. This technique follows the principle of working from the cleanest area to the least clean.
C. Moisten the dressing before removal. A wet-to-dry dressing is meant to adhere to necrotic tissue and debris, which is then removed when the dry dressing is taken off. Moistening it before removal defeats this purpose by softening the dressing, reducing its effectiveness in debriding the wound.
D. Wear sterile gloves to remove the dressing. Clean gloves are appropriate for removing a contaminated dressing. Sterile gloves are necessary for applying the new dressing to maintain an aseptic environment. Using sterile gloves for removal is unnecessary and does not improve infection control.

A. Bradycardia is not a common adverse effect of levodopa-carbidopa. Instead, it may sometimes cause tachycardia (increased heart rate) in some patients. Monitoring for cardiovascular changes is essential, but bradycardia is not typically associated with this medication.
B. Hypotension is a documented adverse effect of levodopa-carbidopa. This medication can cause orthostatic hypotension, which is a drop in blood pressure when standing up, leading to dizziness or fainting. This finding should be carefully monitored and documented, as it can increase the risk of falls.
C. Constricted pupils are not typically an adverse effect of levodopa-carbidopa. Instead, this medication may cause dilated pupils (mydriasis) as a result of its effects on the autonomic nervous system, particularly if the patient is taking other medications that can affect pupil size.
D. Urinary frequency can occur with levodopa-carbidopa; however, it is not commonly classified as a significant adverse effect. While changes in urinary habits can happen, they are more often related to Parkinson's disease itself rather than the medication specifically. Therefore, urinary frequency should be monitored but is not a primary concern compared to hypotension.
