A nurse is planning teaching for a client and their family about home oxygen therapy. Which of the following information should the nurse plan to include in the teaching?

Answer and explanation.

The correct answer is choice A. A nontender, protruding abdomen is a normal finding for a 2year-old toddler. This is due to the immature development of the abdominal muscles and the relatively large size of the liver and kidneys in relation to the rest of the body.

Choice B is wrong because the head circumference should be equal to or less than the chest circumference by age 2. A head circumference that exceeds the chest circumference could indicate hydrocephalus or other neurological problems.

Choice C is wrong because the fontanels, or soft spots on the skull, should be closed by age 18 months. Palpable fontanels could indicate dehydration, malnutrition, or congenital disorders.

Choice D is wrong because the natural loss of deciduous teeth, or baby teeth, usually begins around age 6. Premature loss of teeth could indicate dental caries, trauma, or endocrine disorders.

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.
