A nurse is reviewing the laboratory results of a client who has bulimia nervosa. The nurse should notify the provider of which of the following results?
WBC 5.200/mm3.
Hgb 14 g/dL.
Potassium 3.2 mEq/L.
Magnesium 1.6 mEq/L.
The Correct Answer is C
Choice A rationale:
A white blood cell (WBC) count of 5,200/mm3 is within the normal range, which typically varies but is approximately 4,500-11,000/mm3. This result indicates a normal immune response and does not require provider notification.
Choice B rationale:
A hemoglobin (Hgb) level of 14 g/dL falls within the normal range for adults, which is generally between 12-16 g/dL for women and 13.5-17.5 g/dL for men. This result is not a cause for concern, and the nurse does not need to notify the provider about it.
Choice C rationale:
A potassium (K+) level of 3.2 mEq/L is considered hypokalemia. The normal range for potassium is around 3.5-5.0 mEq/L. Hypokalemia can lead to cardiac dysrhythmias, muscle weakness, and other serious complications. The nurse should notify the provider to address this electrolyte imbalance promptly.
Choice D rationale:
A magnesium (Mg) level of 1.6 mEq/L is below the normal range of approximately 1.7-2.2 mEq/L. While mild hypomagnesemia might not require immediate intervention, it's important to monitor and potentially address this electrolyte imbalance, especially if the client's symptoms worsen. However, it does not warrant immediate notification of the provider.

Correct Answer is C
Explanation
Choice A rationale:
Peanut oil is a good choice for cooking due to its high smoke point and heart-healthy monounsaturated fats. However, when it comes to decreasing saturated fats, canola oil is a better choice.
Choice B rationale:
Stick margarine often contains trans fats, which are known to increase the risk of heart disease. It is not a recommended option, especially for those trying to decrease saturated fats in their diet.
Choice C rationale:
Canola oil is a suitable choice for cooking, especially for individuals at risk for heart disease. It has a high smoke point, is low in saturated fats, and contains heart-healthy monounsaturated fats.
Choice D rationale:
Palm oil is high in saturated fats and is not recommended for cooking when trying to decrease saturated fat intake. It is associated with raising LDL cholesterol levels, which can contribute to heart disease risk.
Correct Answer is D
Explanation
Choice A rationale:
One large tomato does not have a high calcium content. Tomatoes are generally not considered a significant source of calcium.
Choice B rationale:
Green grapes are not a significant source of calcium. They are primarily composed of water and carbohydrates.
Choice C rationale:
A medium banana also does not provide a substantial amount of calcium. Bananas are known for their potassium content more than calcium.
Choice D rationale:
1 cup of broccoli is a good source of calcium. While dairy products are often considered the primary source of dietary calcium, broccoli is a non-dairy option that contains a decent amount of calcium along with other nutrients beneficial for bone health.
