A nurse is instructing a group of clients regarding nutrition. Which of the following is a good source of omega-3 fatty acids that the nurse should include in the teaching?
Fish
Leafy green vegetables
Corn oil
Dietary supplements
The Correct Answer is A
A) Fish: Fish, especially fatty fish like salmon, mackerel, sardines, and trout, are rich sources of omega-3 fatty acids. Omega-3 fatty acids are essential for heart health, reducing inflammation, and supporting brain function. Including fish in the diet is highly recommended for obtaining these beneficial fats naturally.
B) Leafy green vegetables: While leafy green vegetables provide many essential nutrients, they are not significant sources of omega-3 fatty acids. They are more commonly known for their vitamins, minerals, and fiber content, which are important for overall health but do not provide the omega-3s that fish does.
C) Corn oil: Corn oil is high in omega-6 fatty acids rather than omega-3 fatty acids. While omega-6 fatty acids are also necessary for health, they should be balanced with omega-3s to maintain optimal health. Corn oil does not contribute significantly to omega-3 intake.
D) Dietary supplements: While omega-3 supplements can be a good alternative for those who do not consume enough fish, obtaining nutrients from whole foods is generally preferred for additional health benefits, such as protein and other nutrients found in fish. Supplements should be considered when dietary intake is insufficient.

Correct Answer is C
Explanation
The Body Mass Index (BMI) is calculated using the formula:
BMI = weight(kg) / height(m)2
First, we need to convert the height from feet and inches to meters.
There are approximately 0.3048 meters in a foot and 0.0254 meters in an inch.
So, 5 feet 5 inches is approximately 1.65 meters.
Substituting the given values into the formula:
BMI = 60 / (1.65)2
This gives us a BMI of approximately 22 when rounded to the nearest whole number.
Therefore, the correct answer is 22 BMI.
Correct Answer is D
Explanation
A) Size:
When assessing lymph nodes, noting the size is crucial as enlarged lymph nodes can indicate infection, inflammation, or malignancy. Size helps in determining the extent and severity of the underlying condition.
B) Consistency:
The consistency of lymph nodes (whether they are hard, rubbery, or soft) provides important diagnostic information. For instance, hard lymph nodes may suggest malignancy, while soft nodes might indicate an infection.
C) Shape:
Recording the shape of lymph nodes is essential in the assessment process. Regular, oval, or round shapes can be normal, while irregularly shaped nodes might be concerning and warrant further investigation.
D) Color:
Color is not typically assessed or noted when examining lymph nodes. Lymph nodes are internal structures, and their color cannot be directly observed without invasive procedures. The focus is usually on palpable characteristics like size, consistency, and shape.
