Nursing Elites

1. What does 'Excess' mean?

• A. Less than what is needed or usual
• B. More than what is needed or usual
• C. Equal to the amount needed
• D. Below average

Correct answer: B

Rationale: The correct answer is B: 'More than what is needed or usual.' Excess refers to an amount that surpasses what is required or typical. Choice A is incorrect because 'less than what is needed or usual' is the opposite of excess. Choice C is incorrect as 'equal to the amount needed' does not imply excess. Choice D is incorrect as 'below average' does not capture the essence of excess.

2. Which type of radiation involves the emission of helium ions?

• A. Beta
• B. Alpha
• C. Gamma
• D. Delta

Correct answer: B

Rationale: Alpha radiation involves the emission of helium ions. Helium ions are composed of two protons and two neutrons, which is the same as the nucleus of a helium atom. This type of radiation has low penetration power and can be stopped by a piece of paper or human skin, making it less harmful compared to other forms of radiation like beta or gamma radiation. Beta radiation involves the emission of high-speed electrons, while gamma radiation involves electromagnetic waves with high energy. Delta radiation is not a recognized form of radiation in this context, making it an incorrect choice.

3. Select the meaning of the word 'PRN' in the sentence: 'The nurse gave the patient a PRN medication.'

• A. Pinpoint
• B. Relocate
• C. Eradicate
• D. Reduce

Correct answer: D

Rationale: 'PRN' is a medical abbreviation that stands for 'pro re nata,' meaning 'as needed.' In this context, the medication is given to reduce symptoms as they arise. Choice A, 'Pinpoint,' does not align with the meaning of 'PRN.' Choices B and C, 'Relocate' and 'Eradicate,' are unrelated to the concept of 'as needed' medications.

4. How many liters are in 8,000 milliliters?

• A. 0.8 liters
• B. 8 liters
• C. 0.8 liters
• D. 0.08 liters

Correct answer: B

Rationale: There are 1,000 milliliters in a liter. To convert milliliters to liters, you divide by 1,000. Therefore, 8,000 milliliters ÷ 1,000 = 8 liters. This makes option B the correct answer. Option A, 0.8 liters, is incorrect as it is 1/10th of the correct answer. Option C, 0.8 liters (repeated), is also incorrect. Option D, 0.08 liters, is incorrect as it is 1/100th of the correct answer.

5. How many protons does Potassium have?

• A. 18
• B. 19
• C. 20
• D. 21

Correct answer: B

Rationale: Potassium, with the atomic symbol K, has 19 protons, which is equal to its atomic number. The number of protons determines the element's identity, and in the case of Potassium, it is 19. Choice A (18) is incorrect as it does not correspond to Potassium's proton number. Choice C (20) and Choice D (21) are also incorrect as they do not match the actual number of protons in Potassium.
