1. Which food provides a 1-ounce serving of grains for a preschool child?

A. 1 cup of ready-to-eat cereal flakes
B. 1⁄2 slice of whole wheat bread
C. 1⁄2 of a 6-inch flour tortilla
D. 1 cup of cooked rice

Correct answer: A

Rationale: The correct answer is A: 1 cup of ready-to-eat cereal flakes. For a preschool child, 1 cup of ready-to-eat cereal flakes provides a 1-ounce serving of grains, meeting the requirement. Choice B, 1⁄2 slice of whole wheat bread, is not the correct answer as it does not constitute a 1-ounce serving of grains. Similarly, choice C, 1⁄2 of a 6-inch flour tortilla, does not offer a 1-ounce serving of grains. Choice D, 1 cup of cooked rice, also does not provide a 1-ounce serving of grains for a preschool child, making it an incorrect choice.

2. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?

A. Vitamin A
B. Vitamin B12
C. Vitamin C
D. Vitamin E

Correct answer: D

Rationale: Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.

3. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

A. Both statements are true.
B. Both statements are false.
C. The first statement is true; the second is false.
D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

4. Which of the following is reflected in an ECG due to hypokalemia?

A. Tall T waves and Pathologic Q wave
B. Widening QRS Complex and U wave
C. None of the above
D. Both A and B

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

5. The lobe of the brain that contains the auditory receptive areas is the ____________ lobe.

A. temporal
B. frontal
C. parietal
D. occipital

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
