1. Which one of the following best describes the function of a cell membrane?

• A. It controls the substances entering and leaving the cell.
• B. It maintains the cell's shape.
• C. It controls the substances entering the cell.
• D. It supports the cell's structures.

Correct answer: A

Rationale: The correct answer is A. The function of a cell membrane is to control the substances entering and leaving the cell. The cell membrane is selectively permeable, allowing it to regulate the movement of ions and molecules in and out of the cell to maintain internal balance and proper function. Choice B is incorrect because while the cell membrane does provide some structural support, its primary function is not to maintain the cell's shape. Choice C is incorrect because the cell membrane controls both the substances entering and leaving the cell, not just those entering. Choice D is incorrect as the primary function of the cell membrane is not to support the cell's structures but to regulate the movement of substances.

2. Which word is not spelled correctly in the context of the following sentence? I like the way the bride’s stationery complements her wedding decor.

• A. bride’s
• B. stationery
• C. complements
• D. decor

Correct answer: C

Rationale: The word 'complements' is not spelled correctly in the context of the sentence. The correct spelling should be 'complements,' which means 'enhances or goes well with.' 'Compliments' in this context would refer to expressions of praise or admiration. The other choices ('bride’s,' 'stationery,' 'decor') are correctly spelled and fit the context of the sentence.

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. Which of the following is not a principal organ of the nervous system?

• A. Brain
• B. Thymus
• C. Ganglia
• D. Spinal cord

Correct answer: B

Rationale: The correct answer is B. The thymus is not a principal organ of the nervous system; it is part of the immune system. The brain, spinal cord, and ganglia are principal organs of the nervous system. The brain is responsible for processing information, the spinal cord helps transmit signals between the brain and the rest of the body, and ganglia are clusters of nerve cells that support the nervous system's functions. Therefore, the thymus is the correct answer as it is not directly involved in nervous system functions.

5. Which verb correctly completes the sentence? After throwing their sleeping bags into the backseat of their car, they ___ more than 400 miles to reach their destination.

• A. Driving
• B. Having driven
• C. Drove
• D. Had drove

Correct answer: C

Rationale: In this sentence, the action of driving more than 400 miles is a past action that already took place after they threw their sleeping bags into the backseat. 'Drove' is the correct past tense form of the verb to match this past action. Choice A, 'Driving,' is in the present participle form and does not correctly indicate the completion of the action in the past. Choice B, 'Having driven,' is in the present perfect form and does not fit the sequence of events in the sentence. Choice D, 'Had drove,' is incorrect due to the incorrect use of 'had' with the past form of 'drive.' Therefore, the most appropriate choice is 'Drove.'
