Nursing Elites

1. How many amino acids are essential?

• A. 5
• B. 7
• C. 9
• D. 13

Correct answer: C

Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.

2. Intrinsic factor from the stomach is needed for the absorption of which vitamin?

• A. vitamin B12
• B. folate
• C. niacin
• D. vitamin B6

Correct answer: A

Rationale: The correct answer is A: vitamin B12. Intrinsic factor is a glycoprotein produced by the stomach that is necessary for the absorption of vitamin B12 in the small intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is then absorbed in the ileum. This absorption process is crucial for preventing vitamin B12 deficiency. Choices B, C, and D are incorrect because they do not require intrinsic factor for absorption. Folate is absorbed in the small intestine through a different mechanism, niacin can be absorbed in the small intestine without the need for intrinsic factor, and vitamin B6 does not rely on intrinsic factor for absorption.

3. 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.

4. What is the most appropriate instruction to provide to the parent of a child who does not like a food item?

• A. The child should not be encouraged to try it again.
• B. The child should be offered a reward if they eat most of the food items.
• C. The child should be offered the item at least 8 times on different occasions.
• D. The child should be encouraged to eat at least 5 bites of the food item.

Correct answer: C

Rationale: The correct answer is C. Encouraging repeated exposure to the food item can help the child develop a taste for it. Option A is incorrect as it suggests avoiding encouraging the child to try the food again, which may hinder their ability to develop a liking for it. Option B is incorrect as using rewards for eating may not promote a genuine interest in the food item. Option D is incorrect because setting a specific number of bites may create pressure and negativity around mealtime, rather than fostering a positive association with the food.

5. Salome was fitted a hearing aid. She understood the proper use and wear of this device when she says that the battery should be functional, the device is turned on and adjusted to a:

• A. therapeutic level
• B. comfortable level
• C. prescribed level
• D. audible level

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.
