Down and back
Up and back
Down and forward
Straight back
None
None
The Correct Answer is B
A. This option is appropriate for children under the age of 3. Pulling the pinna down and back straightens the ear canal in young children, but it does not align the canal correctly in adults.
B. For an adult, the correct method to straighten the ear canal during examination is to pull the pinna (outer part of the ear) up and back. This maneuver aligns the ear canal for better visualization of the tympanic membrane (eardrum) and inner structures.
C. Pulling the pinna down and forward is incorrect for both adults and children. This action would not provide a clear view of the ear canal and could make examination difficult.
D. Pulling the pinna straight back does not fully straighten the ear canal in adults and may make the examination less effective. The correct technique is up and back for adults to fully straighten the canal and enhance visualization.

Correct Answer is A
Explanation
This is the food selection that has the highest fiber content per cup. According to the web search results, one cup of cooked lentils provides about 15.6 grams of fiber, which is more than half of the minimum daily requirement²³ . Lentils are also rich in protein, iron, and folate, which are important nutrients for pregnant women.
The other food selections have lower fiber content per cup.
b) Asparagus
Asparagus is a green vegetable that is high in vitamin K, folate, and antioxidants. However, it is not very high in fiber. One cup of cooked asparagus provides only about 2.8 grams of fiber².
c) Oatmeal
Oatmeal is a whole grain that is high in beta-glucan, a type of soluble fiber that can lower cholesterol and blood sugar levels. However, it is not the highest in fiber among the food selections. One cup of cooked oatmeal provides about 4 grams of fiber.
d) Cabbage
Cabbage is a cruciferous vegetable that is low in calories and high in vitamin C, vitamin K, and glucosinolates. However, it is not very high in fiber. One cup of cooked cabbage provides only about 2.9 grams of fiber².
Correct Answer is B
Explanation
The nurse is assessing the 6 stages of the cardinal gaze to evaluate the function of the cranial nerves III, IV, and VI for ocular motor movements, which control eye movement and positioning.
Cranial nerve III controls the superior rectus, inferior rectus, and medial rectus muscles, which move the eye up, down, and inward, respectively. Cranial nerve IV controls the superior oblique muscle, which moves the eye downward and laterally. Cranial nerve VI controls the lateral rectus muscle, which moves the eye outward.
Therefore, the nurse will observe the patient's ability to move their eyes smoothly in each of the six cardinal positions of gaze and note any abnormalities that may indicate dysfunction of these cranial nerves. This test is used to diagnose conditions such as strabismus, nystagmus, and palsy of the ocular motor nerves.
Cranial nerve II, on the other hand, is responsible for visual acuity, not eye movement, and is tested separately using a visual acuity chart or other vision tests.
