Nursing Elites

1. What would be an appropriate nursing response when a mother reports that her 16-month-old toddler has an earache?

• A. Maybe the toddler is just teething.
• B. I will check her ear for an ear infection.
• C. Are you sure the toddler is really in pain?
• D. Please describe what the toddler is doing to indicate she is in pain.

Correct answer: B

Rationale: The appropriate nursing response would be to assess the toddler's ear to determine if there is indeed an ear infection causing the earache. It is crucial to provide timely and suitable care for the child's pain and discomfort. Checking for an ear infection is a necessary step in evaluating the source of the toddler's earache. Choice A is incorrect as it assumes the earache is due to teething without proper assessment. Choice C questions the mother's report rather than focusing on the child's condition. Choice D is not as direct and focused as directly examining the ear for a possible infection.

2. What is the primary function of the heart in the circulatory system?

• A. To filter blood
• B. To pump blood throughout the body
• C. To absorb oxygen
• D. To remove carbon dioxide

Correct answer: B

Rationale: The correct answer is B: 'To pump blood throughout the body.' The primary function of the heart in the circulatory system is to pump blood, which carries oxygen and nutrients, throughout the body. Choice A, 'To filter blood,' is incorrect as the heart does not filter blood; that is primarily done by the kidneys. Choice C, 'To absorb oxygen,' is incorrect as the lungs are responsible for oxygen absorption. Choice D, 'To remove carbon dioxide,' is incorrect as the lungs facilitate the removal of carbon dioxide from the body.

3. A stye is an infection of the ___________.

• A. eyelid
• B. eardrum
• C. nostril
• D. scalp

Correct answer: A

Rationale: A stye is an infection that occurs at the base of an eyelash or on the eyelid. It is typically caused by a bacterial infection, leading to redness, swelling, and sometimes discomfort in the affected area. Choices B, C, and D are incorrect because a stye specifically refers to an infection of the eyelid area, not the eardrum, nostril, or scalp.

4. What is the typical oxidation state of oxygen in most compounds?

• A. -1
• B. -2
• C. 0
• D. -3

Correct answer: B

Rationale: The correct answer is B: "-2". Oxygen usually exhibits an oxidation state of -2 in most compounds. This is due to oxygen's high electronegativity, which causes it to attract electrons, leading to the gain of two electrons in chemical reactions. Choice A (-1) is incorrect because oxygen rarely has an oxidation state of -1 in compounds. Choice C (0) is incorrect as oxygen does not usually have an oxidation state of zero in compounds. Choice D (-3) is incorrect as oxygen does not commonly have an oxidation state of -3 in compounds.

5. Solve for x: x/250 = 3/500

• A. 1.5
• B. 25.5
• C. 1500
• D. 2.5

Correct answer: A

Rationale: To solve for x in the equation x/250 = 3/500, you can cross-multiply: x*500 = 3*250. Therefore, 500x = 750. Now, divide both sides by 500: x = 750/500. Simplifying, x = 1.5. Therefore, the correct answer is A, 1.5. Choice B, 25.5, is incorrect as it does not match the correct calculation. Choice C, 1500, is incorrect as it is not the result of solving the equation given. Choice D, 2.5, is incorrect as well, as it does not align with the correct value of x obtained from the equation.
