A nurse is assessing a client who has heart failure and a new prescription for metoprolol. Which of the following findings should the nurse identify as an adverse effect of the medication?

Choice A reason: Changing the ostomy pouch daily is not necessary and could lead to skin irritation from the frequent removal and application of the adhesive. Ostomy pouches are designed to be worn for several days, and the schedule for changing them can vary based on the type of pouch and individual needs.

Choice B reason: Emptying the ostomy pouch when it is 2/3 full is the correct instruction. This prevents the pouch from becoming too heavy, which could pull on the stoma and cause discomfort or damage. It also reduces the risk of leaks and odors.

Choice C reason: Trimming the opening of the ostomy seal to be 1/2 inch wider than the stoma is incorrect. The opening should be trimmed to match the size of the stoma to provide a secure fit and prevent leakage of the contents onto the skin, which could cause irritation or infection.

Choice D reason: Applying lotion to the peristomal skin when changing the ostomy pouch is not recommended. Lotions or creams can interfere with the adhesive of the ostomy appliance and reduce the effectiveness of the seal. The peristomal skin should be clean and dry to ensure the best adherence of the ostomy appliance.

Choice A reason: Serosanguineous drainage, which is a mixture of blood and a clear yellow liquid known as serum, is generally expected after surgery. While the amount of 150 mL may seem significant, it is not uncommon in the first hour postoperatively, especially after abdominal surgery. The nurse should continue to monitor the drainage and report if the volume increases significantly or if the drainage becomes bright red, indicating active bleeding.

Choice B reason: Greenish-yellow drainage is typically bile, which can be present in NG tube drainage after abdominal surgery. This type of drainage is not unusual and does not necessarily need to be reported unless accompanied by other concerning symptoms or changes in the patient's condition.

Choice C reason: 100 mL of red drainage is concerning and should be reported to the provider immediately. Red drainage suggests active bleeding, and in the context of the first postoperative hour, it could indicate a complication such as hemorrhage. Prompt assessment and intervention are required to address this potential emergency situation.

Choice D reason: Brown drainage may be old blood or could be related to the contents of the gastrointestinal tract. While 200 mL is a larger volume, brown drainage is not typically as concerning as bright red drainage. However, the nurse should monitor for changes in the color and consistency of the drainage, as well as the patient's vital signs and overall status.
