Nursing Elites

1. The nurse asked the patient to choose the items from the menu that are his _____.

• A. favorites
• B. selections
• C. preferences
• D. choices

Correct answer: A

Rationale: The correct answer is 'favorites.' In this context, 'favorites' best describes the patient's personal preferences from the menu. The nurse is asking the patient to select the items they like the most. While 'selections' and 'choices' could also work in this context, 'favorites' specifically highlights the items the patient prefers above all others. 'Preferences' is not as fitting as 'favorites' because it generally refers to a broader range of likes and dislikes rather than specific favorite items.

2. If bacteria are placed in a strong solution of salt water, they will shrink as water moves out of the bacteria. What is this process called?

• A. Dehydration synthesis
• B. Hydrolysis
• C. Osmosis
• D. Isotonic transport

Correct answer: C

Rationale: Osmosis is the process by which water molecules move across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this case, when bacteria are placed in a strong solution of salt water, the high concentration of solutes outside the bacteria causes water to move out of the bacteria, leading to shrinkage. This process is known as osmosis. Dehydration synthesis (Choice A) is a process where molecules combine by removing water. Hydrolysis (Choice B) is the breakdown of molecules by the addition of water. Isotonic transport (Choice D) does not accurately describe the specific movement of water in or out of bacterial cells in a hypertonic solution.

3. Add 7/8 + 9/10 + 6/5. Express the result as a mixed number.

• A. 3 & 39/40
• B. 3 & 22/23
• C. 22/23
• D. 2 & 39/40

Correct answer: A

Rationale: To add fractions, find a common denominator, which in this case is 40. Convert each fraction to have the common denominator: 7/8 = 35/40, 9/10 = 36/40, and 6/5 = 48/40. Add these fractions to get 119/40. Simplify this improper fraction to a mixed number, which is 3 & 39/40. Choice B and C are incorrect as they do not represent the sum of the fractions. Choice D is incorrect; the whole number part should be 3, not 2.

4. Select the word or phrase in the sentence that is not used correctly: 'Her teacher asked her what would she do after she graduated from nursing school.'

• A. She
• B. From
• C. Would
• D. Her

Correct answer: C

Rationale: The correct answer is C. The phrase 'what would she do' is incorrect because in English questions, the word order for modal verbs like 'would' should be 'she would do' instead of 'would she do'. The correct structure should be 'her teacher asked her what she would do after she graduated from nursing school.' Choices A, B, and D are used correctly in the sentence and do not contain any errors.

5. Which of the following substances has the highest density?

• A. Mist
• B. Water
• C. Steam
• D. Ice

Correct answer: B

Rationale: Water has the highest density among the options provided. Density is a measure of mass per unit volume. In this case, water in its liquid form is denser than mist, steam, and ice. Ice has a lower density than water because its crystalline structure causes it to be less dense. Mist and steam are forms of water vapor, which are much less dense than liquid water. Therefore, the correct answer is water (choice B).
