A nurse is caring for a school-age child who is 2 hr postoperative following cardiac catheterization.

The nurse observes blood on the child’s dressing.

Which of the following actions should the nurse take?

The client has signs of dehydration and oliguria, which are low urine output and dark yellow urine. A fluid bolus can help restore the fluid balance and improve the renal perfusion. The normal urine output for an adult is 0.5-1.5 mL/kg/hr, and the client’s urine output is only 25 mL/hr, which is below the minimum acceptable level. Dark yellow urine can indicate a high concentration of waste products and a low intake of fluids.

Choice B is wrong because continuous bladder irrigation is used to prevent or treat blood clots in the bladder after surgery or injury, not to increase urine output.

Choice C is wrong because a urine specimen for culture and sensitivity is used to diagnose a urinary tract infection, which is not the most likely cause of the client’s low urine output.

The client does not have other symptoms of infection, such as fever, pain, or cloudy urine.

Choice D is wrong because clamping the catheter tubing for 30 min can cause urinary retention, bladder distension, and increased risk of infection.

It can also interfere with the accurate measurement of urine output.

Fish is a good source of protein and omega-3 fatty acids, which can help lower blood pressure, reduce inflammation, and prevent blood clots. Fish is also low in sodium, which is important for people with hypertension, as excess sodium can raise blood pressure by retaining fluid in the body. Fish is part of the DASH diet, which stands for Dietary Approaches to Stop Hypertension, and is a healthy eating plan that emphasizes fruits, vegetables, whole grains, low-fat dairy, nuts, seeds, legumes, and lean meats.

Choice A. Cheese is wrong because cheese is high in sodium and saturated fat, which can increase blood pressure and cholesterol levels.
Cheese should be limited or avoided by people with hypertension.

Choice C. Red meat is wrong because red meat is also high in sodium and saturated fat, as well as cholesterol, which can contribute to hypertension and heart disease.
Red meat should be eaten sparingly or replaced by leaner sources of protein like fish, poultry, or beans.

Choice D. Canned black beans are wrong because canned black beans are high in sodium, as most canned foods are preserved with salt. Canned black beans should be rinsed well before eating or replaced by dried or cooked black beans, which are lower in sodium and high in fiber, potassium, magnesium, and calcium, which are beneficial for blood pressure control.
