Nursing Elites

1. Choose the meaning of the word 'contusions' in the following sentence: 'Contusions or scratches may be treated on-site.'

• A. Breaks
• B. Disorientation
• C. Bruises
• D. Abrasions

Correct answer: C

Rationale: The correct answer is C: 'Bruises.' In the context of the sentence provided, 'contusions' refers to injuries that cause discoloration or bruising of the skin without breaking the skin. The word 'contusions' is synonymous with bruises, not breaks (choice A), disorientation (choice B), or abrasions (choice D). Therefore, in the sentence, contusions or scratches are mentioned as potential injuries that may require treatment on-site.

2. Which of the following organelles are responsible for producing cell energy?

• A. Mitochondrion and chloroplast
• B. Mitochondrion and nucleus
• C. Chloroplast and nucleus
• D. Chloroplast and lysosome

Correct answer: A

Rationale: The correct answer is A: Mitochondrion and chloroplast. Mitochondria and chloroplasts are the organelles responsible for producing cell energy through cellular respiration and photosynthesis, respectively. Choice B is incorrect because the nucleus is not involved in energy production. Choice C is incorrect as the nucleus is not an organelle that produces energy. Choice D is incorrect as lysosomes function in digesting waste materials, not in energy production.

3. Three nurses worked 8-hour shifts. Nurse 1 monitored 6 patients during her shift. Nurse 2 monitored 8 patients, and Nurse 3 monitored 12 patients. How many patients were monitored in total?

• A. 26 patients
• B. 24 patients
• C. 20 patients
• D. 23 patients

Correct answer: A

Rationale: To find the total number of patients monitored, add the patients monitored by each nurse: 6 (Nurse 1) + 8 (Nurse 2) + 12 (Nurse 3) = 26 patients. Therefore, the correct answer is 26 patients. Choice B (24 patients), Choice C (20 patients), and Choice D (23 patients) are incorrect as they do not correctly sum up the patients monitored by each nurse.

4. He tried to remember the names of all the people who were there that night.

• A. that
• B. who
• C. which
• D. whom

Correct answer: B

Rationale: In this context, 'who' is the correct relative pronoun to refer to people. 'That' is used for things, 'which' is used for animals or things, and 'whom' is an object pronoun, not needed in this sentence. Therefore, 'who' is the most appropriate choice.

5. What is the correct formula for potassium chloride?

• A. NaCl
• B. KCl
• C. KCl
• D. ClK

Correct answer: B

Rationale: The correct formula for potassium chloride is KCl. In chemical formulas, the symbol for the cation (positive ion) comes first followed by the symbol for the anion (negative ion). Potassium is represented by the symbol K, while chloride is represented by the symbol Cl. Therefore, the formula for potassium chloride is KCl. Choice A (NaCl) is the formula for sodium chloride, not potassium chloride. Choice C is a duplicate of choice B, and choice D (ClK) is an incorrect arrangement of the symbols for potassium and chloride.
