A nurse in an emergency department is caring for a client who has a closed head injury. Which of the following actions should the nurse take first?

The correct answer is choice B. Apply direct pressure to the puncture site.

Choice A rationale:

Applying intermittent pressure 2.5 cm (1 inch) below the percutaneous skin site is not the best approach. This method may not effectively control the bleeding and could potentially dislodge the introducer sheath.

Choice B rationale:

Applying direct pressure to the puncture site is the most effective way to control bleeding. Direct pressure helps to promote clot formation and reduce blood flow to the area, which is crucial in managing postoperative bleeding.

Choice C rationale:

Elevating the affected extremity above the level of the heart is not appropriate in this situation. While elevation can reduce swelling, it does not address the immediate need to control active bleeding.

Choice D rationale:

Leaving the dressing undisturbed and notifying the physician immediately is not advisable. Immediate action to control the bleeding is necessary before notifying the physician. Delaying intervention could lead to significant blood loss.

The correct answer is choice B. Fish. 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.
