A nurse in an urgent care clinic is collecting data from a client who reports having diarrhea for the past 3 days. Which of the following findings indicates hypokalemia?

b. "You can use an adhesive remover when changing the colostomy skin barrier."

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.

Answer: A

Rationale:

A) Ampicillin: Ampicillin is contraindicated for this client because it belongs to the penicillin class of antibiotics. Since the client is allergic to penicillin, administering ampicillin could trigger an allergic reaction, which could range from mild rash to severe anaphylaxis.

B) Erythromycin: Erythromycin is a macrolide antibiotic and can be used as an alternative for clients who are allergic to penicillin. It is often prescribed for group B streptococcus infections in penicillin-allergic clients, making it a suitable option in this case.

C) Cefazolin: Cefazolin is a cephalosporin antibiotic and is generally considered safe for clients with a penicillin allergy, except in cases of severe penicillin allergies. Cross-reactivity is low, and cefazolin can be an appropriate choice for treating group B streptococcus.

D) Clindamycin: Clindamycin is a lincosamide antibiotic and is often used for clients with penicillin allergies. It is effective against group B streptococcus and does not belong to the penicillin or cephalosporin classes, making it a suitable option for this client.
