1. LABILE also means .

• A. Extremely changing
• B. Suicidal
• C. Rapidly changing
• D. With a high fever

Correct answer: A

Rationale: The word 'labile' is used to describe something that is constantly changing or easily altered. Therefore, the best synonym for 'labile' is 'extremely changing.' Choice B, 'suicidal,' is incorrect as it does not relate to the meaning of 'labile.' Choice C, 'rapidly changing,' is close but not as precise as 'extremely changing.' Choice D, 'with a high fever,' is completely unrelated to the meaning of 'labile.'

2. What does the term 'bilingual' mean in the sentence: 'Being bilingual is an advantage for a nurse'?

• A. Able to speak more than one language
• B. Able to use either hand
• C. Not squeamish about blood
• D. Can remember everything

Correct answer: A

Rationale: The correct answer is A: 'Able to speak more than one language.' In the context provided, 'bilingual' refers to the ability to speak two languages. This is advantageous for a nurse who may need to communicate with patients from diverse linguistic backgrounds. Choices B, C, and D are incorrect because they do not align with the meaning of 'bilingual' as the ability to speak multiple languages.

3. Which hormone is produced by the pineal gland?

• A. Corticosteroid
• B. Oxytocin
• C. Prolactin
• D. Melatonin

Correct answer: D

Rationale: Melatonin is the hormone produced by the pineal gland. It plays a crucial role in regulating the sleep-wake cycle and is instrumental in maintaining the body's circadian rhythm. Melatonin production is triggered by darkness and inhibited by light, aiding in signaling the body when it is time to sleep. Corticosteroid, oxytocin, and prolactin are hormones produced by other glands in the body and are not associated with the pineal gland. Therefore, they are incorrect choices for this question.

4. The lateral side of the right knee would be ___________.

• A. the kneecap
• B. closest to the left knee
• C. farthest from the left knee
• D. on the underside of the knee

Correct answer: C

Rationale: The lateral side of the right knee is the side that is farthest from the left knee when looking at the knee joint from the front. The term 'lateral' refers to the side of the body that is farther away from the midline or center of the body. In this case, the lateral side of the right knee is on the outer side of the knee joint, away from the other knee. Choice A is incorrect as the kneecap is located at the front of the knee. Choice B is incorrect as it describes the medial side, not the lateral side. Choice D is incorrect as it refers to the underside, which is not related to the lateral aspect of the knee.

5. What form of radiation is composed of electrons traveling at around 16,000 km/sec?

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

Correct answer: B

Rationale: Beta radiation is composed of high-energy electrons (β- particles) or positrons (β+ particles) traveling at considerable speeds. In this case, the electrons traveling at around 16,000 km/sec align with the characteristics of beta radiation, making it the correct choice. Alpha radiation consists of helium nuclei, gamma radiation is electromagnetic radiation of high frequency, and delta radiation is not a recognized form of radiation, making them all incorrect choices.
