A nurse is reviewing the medical record for a client who is at 38 weeks of gestation, tested positive for group B streptococcus B-hemolytic, and is allergic to penicillin. The nurse should identify that which of the following medications is contraindicated for this client?

Delegating tasks involves assigning appropriate responsibilities to assistive personnel based on their level of training, competency, and scope of practice. Performing indwelling urinary catheter care is a task that can be safely delegated to an AP who has received proper training and demonstrated competency in this skill. The nurse should ensure that the AP is familiar with the facility's policies and procedures regarding catheter care and can perform the task safely and effectively.

Demonstrating how to use an incentive spirometer requires specialized knowledge and the ability to provide clear instructions. It is typically within the scope of practice of licensed healthcare professionals, such as nurses or respiratory therapists, who have the necessary expertise to properly educate and guide patients in using an incentive spirometer. This task should not be delegated to an AP.

Measuring and assessing the depth of a pressure injury requires clinical judgment and accurate evaluation, which falls within the scope of practice of a licensed nurse. It involves understanding wound assessment, proper technique for measuring depth, and interpreting the findings. This task should be performed by the nurse rather than an AP.

Changing the appliance on a new colostomy involves skills such as assessing the stoma, selecting the appropriate appliance, and ensuring proper application. This task requires specialized knowledge and training in stoma care, and it should be performed by a licensed nurse who has the expertise in managing ostomies. It should not be delegated to an AP.

The nurse should inform the client that they can use an adhesive remover when changing the colostomy skin barrier. Adhesive removers are helpful in gently removing the adhesive residue left behind by the previous ostomy appliance. This can make the process of changing the colostomy skin barrier more comfortable for the client and help prevent skin irritation or damage.

Explanation for the other options:

a. "You should scrub the skin around the colostomy when cleaning." Scrubbing the skin around the colostomy can be harsh and may cause skin irritation or damage. It is recommended to clean the peristomal skin gently using mild soap and water, followed by thorough drying.

c. "You will need a device to suction stool from the colostomy bag." Suctioning stool from the colostomy bag is not a routine procedure for colostomy care. Colostomy bags are designed to collect stool, and emptying the bag as needed is the appropriate method of management.

d. "You should empty the colostomy bag when it is three-fourths full." The timing of emptying the colostomy bag may vary for each individual. It is generally recommended to empty the colostomy bag when it is one-third to one-half full to prevent leakage or discomfort. The client should be educated on monitoring the bag and emptying it as necessary based on their own output and comfort level.
