A nurse is providing care for a client who experienced a myocardial infarction prior to a cardiac arrest. Which of the following laboratory tests will identify early injury to the cardiac muscle?

Wound dehiscence can lead to infection, bleeding, and evisceration (protrusion of internal organs through the incision). The nurse should report this finding to the provider immediately and cover the wound with a sterile dressing moistened with sterile saline solution.

Choice A is wrong because mild swelling under the sutures near the incisional line is a normal finding in the early stages of wound healing. It does not indicate infection or dehiscence unless accompanied by other signs such as redness, warmth, pain, or purulent drainage.

Choice B is wrong because crusting of exudate on the incisional line is also a normal finding that indicates the formation of a scab.

A scab protects the wound from infection and helps it heal faster. The nurse should not remove the scab unless instructed by the provider.

Choice D is wrong because pink-tinged coloration on the incisional line is another normal finding that shows healthy granulation tissue.

Granulation tissue is new tissue that fills in the wound and helps it close. It is usually pink or red and moist.

The nurse should follow these general tips for postoperative abdominal incision care:

• Always wash your hands before and after touching your incisions.
• Inspect your incisions and wounds every day for signs your healthcare provider has told you are red flags or concerning.
• Look for any bleeding.

If the incisions start to bleed, apply direct and constant pressure to the incisions.

• Avoid wearing tight clothing that might rub on your incisions.
• Try not to scratch any itchy wounds.
• You can shower starting 48 hours after your operation but no scrubbing or soaking of the abdominal wounds in a tub.
• After the initial dressing from the operating room is removed, you can leave the wound open to air unless there is drainage or you feel more comfortable with soft gauze covering the wound.
• Surgical glue (Indermil) will fall off over a period of up to 2-3 weeks.

Do not put any topical ointments or lotions on the incisions.

• Do not rub over the incisions with a washcloth or towel.
• No tub baths, hot tubs, or swimming until evaluated at your clinic appointment.

Choice A reason:

Eating 1 g/kg of protein per day is the appropriate recommendation. When providing discharge teaching to a client with chronic kidney disease (CKD) who is receiving haemodialysis, the nurse should include the instruction to eat an appropriate amount of protein, which is usually recommended at a specific daily intake based on the client's weight.

Clients with CKD often have dietary restrictions, including limiting protein intake to reduce the workload on the kidneys. However, protein intake is still necessary for maintaining muscle mass and overall health. The recommended protein intake for clients with CKD undergoing haemodialysis is typically around 1 gram of protein per kilogram of body weight per day.

Choice B reason:

Drink at least 3 L of fluid daily. Clients receiving haemodialysis typically have fluid restrictions, as impaired kidney function can lead to fluid retention and electrolyte imbalances. The specific fluid allowance will be determined by the healthcare provider based on the client's individual needs, and it may be significantly less than 3 L per day.

Choice Doption

Take magnesium hydroxide for ingestion. Magnesium hydroxide is a laxative and antacid used to relieve constipation and heartburn. It is not typically prescribed for clients with chronic kidney disease, especially without proper evaluation of their kidney function and overall medical condition.

Choice Coption:

C. Consume foods high in potassium.

Clients with chronic kidney disease, especially that undergoing haemodialysis, often need to restrict potassium intake. Impaired kidney function can lead to the build-up of potassium in the blood, which can be harmful. Therefore, it is essential for clients with CKD to avoid or limit foods high in potassium.
