A nurse is teaching a class about dietary guidelines to promote cardiovascular health. Which of the following recommendations should the nurse include in the teaching?
Increase intake of whole grains.
Increase intake of refined carbohydrates.
Decrease intake of potassium.
Decrease intake of omega-3 fatty acids.
The Correct Answer is A
In teaching about dietary guidelines to promote cardiovascular health, the nurse should include the recommendation to increase the intake of whole grains. Whole grains, such as whole wheat, brown rice, oats, and quinoa, are rich in fiber, vitamins, minerals, and phytochemicals that are beneficial for cardiovascular health. They can help lower cholesterol levels, improve blood sugar control, and reduce the risk of heart disease.
The other choices are incorrect:
Increasing the intake of refined carbohydrates is not a recommended recommendation for promoting cardiovascular health. Refined carbohydrates, such as white bread, white rice, and sugary snacks, have been associated with an increased risk of heart disease. They are often low in fiber and can cause spikes in blood sugar levels, leading to poor cardiovascular health outcomes.
Decreasing the intake of potassium is also not a recommended recommendation. Potassium is an essential mineral that plays a vital role in maintaining heart health and blood pressure regulation. Adequate intake of potassium-rich foods, such as bananas, avocados, spinach, and sweet potatoes, can help lower blood pressure and reduce the risk of cardiovascular diseases.
Decreasing intake of omega-3 fatty acids is incorrect as well. Omega-3 fatty acids, found in fatty fish (such as salmon, mackerel, and sardines), flaxseeds, chia seeds, and walnuts, have been shown to have numerous cardiovascular benefits. They can help reduce inflammation, lower triglyceride levels, improve heart rhythm, and decrease the risk of heart disease. Therefore, it is important to include omega-3 fatty acids in the diet for optimal cardiovascular health.

Correct Answer is B
Explanation
Wipe dentures before storing them in a dry container at night: This is a correct instruction. Before storing dentures overnight, it is important to remove debris and rinse them with water. Wiping the dentures helps to remove any remaining residue or particles and keeps them relatively clean until the next use. Storing dentures in a dry container helps prevent the growth of microorganisms and maintains the shape of the dentures.
Wrap gloved fingers with gauze to remove dentures: This is not the recommended technique for removing dentures. Instead, it is recommended to use a denture brush or a soft-bristled toothbrush with a non-abrasive denture cleaner or mild soap to clean the dentures. The use of gauze may not provide adequate cleaning and may cause damage to the denture surface.
Use a washcloth to clean the denture surfaces: A washcloth is not the ideal tool for cleaning dentures. Instead, a denture brush or a soft-bristled toothbrush should be used. These tools are specifically designed to clean denture surfaces effectively without causing damage.
Floss dentures as part of daily cleaning: Flossing is not necessary for denture cleaning since dentures do not have natural teeth or spaces between them. However, it is important to clean all surfaces of the dentures using a denture brush or a soft-bristled toothbrush to remove plaque, debris, and stains.
Correct Answer is C
Explanation
Iron-deficiency anemia is characterized by a deficiency of iron, which is necessary for the production of hemoglobin in red blood cells. Ferritin is a protein that stores iron in the body, and a low ferritin level is an indicator of depleted iron stores.
Ferritin: The normal range for ferritin varies depending on the laboratory, but typically it is around 12 to 300 ng/mL for females and 12 to 500 ng/mL for males. A client with a ferritin level of 8 ng/mL has a significantly low level, suggesting iron-deficiency anemia due to depleted iron stores.
Hematocrit: The normal range for hematocrit is around 36% to 46% for females and 38% to 50% for males. A client with a hematocrit of 42% falls within the normal range and does not suggest iron-deficiency anemia.
Hemoglobin: The normal range for hemoglobin is approximately 12 to 16 g/dL for females and
13.5 to 17.5 g/dL for males. A client with a hemoglobin level of 15 g/dL is within the normal range and does not indicate iron-deficiency anemia.
RBC count: The normal range for red blood cell (RBC) count is roughly 4.2 to 5.4 million/mm3 for females and 4.7 to 6.1 million/mm3 for males. A client with an RBC count of 5.2 million/mm3 falls within the normal range and does not indicate iron-deficiency anemia.
