Nursing Elites

1. Which of the following statements is a fact?

• A. Nurses should watch for jaundice in newborns.
• B. Untreated jaundice may cause brain damage.
• C. Phototherapy blankets are a valuable invention.
• D. Avoid neonatal units that lack phototherapy.

Correct answer: B

Rationale: The correct answer is B: 'Untreated jaundice may cause brain damage.' This statement is a fact supported by the passage. Neonatal jaundice, if left untreated, can lead to brain damage due to excess bilirubin levels in the blood. Choice A is not a fact but a general guideline for nurses. Choice C is an opinion as it describes phototherapy blankets as valuable without citing a specific fact. Choice D is not a fact but a recommendation, advising to avoid neonatal units lacking phototherapy.

2. If the quotient is 4 and the dividend is 12, what is the divisor?

• A. 3
• B. 6
• C. 4
• D. 9

Correct answer: C

Rationale: To find the divisor, you need to divide the dividend by the quotient. In this case, the dividend is 12 and the quotient is 4. Dividing 12 by 4 gives you the divisor, which is 3. Therefore, the correct answer is 4. Choices A, B, and D are incorrect because they do not result from dividing the dividend by the quotient in this scenario.

3. What is the correct name of AgNO₃?

• A. Argent nitrous
• B. Argent oxide
• C. Silver nitrite
• D. Silver nitrate

Correct answer: D

Rationale: The correct name for AgNO₃ is silver nitrate. In chemical nomenclature, the element symbol Ag represents silver, and the polyatomic ion NO₃ is known as nitrate. Therefore, when the silver ion (Ag⁺) combines with the nitrate ion (NO₃⁻), the resulting compound is named silver nitrate (AgNO₃). Choices A, B, and C are incorrect because they do not accurately represent the composition of AgNO₃. Argent nitrous (Choice A) and Argent oxide (Choice B) do not reflect the correct anion, and Silver nitrite (Choice C) uses a different anion altogether.

4. Select the word or phrase that is misplaced in the following sentence. In the apartment house, the car with the white roof and new tires belongs to our friends.

• A. In the apartment house
• B. with the white roof
• C. and new tires
• D. to our friends

Correct answer: C

Rationale: The phrase 'and new tires' is misplaced in the sentence as it disrupts the flow of information. It introduces unnecessary detail that does not directly contribute to the main point of the sentence, which is identifying the ownership of the car. Choices A, B, and D are all essential parts of the sentence that help convey the location of the car and its ownership, making them correctly placed within the sentence.

5. Which type of radiation emits helium ions and can be stopped by a piece of paper?

• A. Beta radiation
• B. Alpha radiation
• C. Gamma radiation
• D. X-ray radiation

Correct answer: B

Rationale: Alpha radiation emits helium ions, which are helium nuclei without electrons, making them positively charged. These ions are relatively large and heavy compared to beta and gamma radiation. Due to their size and charge, alpha particles interact strongly with matter and are easily stopped. A piece of paper or even human skin can effectively block alpha radiation. Therefore, alpha radiation is the type of radiation that can be stopped by a piece of paper. Beta radiation consists of fast-moving electrons and can penetrate further into materials than alpha radiation, thus not stopped by a piece of paper. Gamma radiation is highly penetrating and requires dense materials like lead or concrete to block it effectively. X-ray radiation, similar to gamma radiation, is also highly penetrating and cannot be stopped by a piece of paper.
