1. Which organelle is responsible for breaking down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks?

• A. Golgi apparatus
• B. Mitochondria
• C. Lysosomes
• D. Endoplasmic reticulum

Correct answer: C

Rationale: Rationale: Lysosomes are membrane-bound organelles containing digestive enzymes that break down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks. These enzymes help in the process of intracellular digestion and recycling of cellular components. The Golgi apparatus is involved in processing and packaging proteins for secretion or for use within the cell. Mitochondria are responsible for producing energy in the form of ATP through cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism.

2. One staff suggests that they review the pattern of nursing care that they are using, which is

• A. job description
• B. system used to deliver care
• C. manual of procedure
• D. rules to be followed

Correct answer: B

Rationale: The correct answer is B: 'system used to deliver care.' When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.

3. A study finds a link between increased screen time and lower academic performance. What additional information would be most helpful in interpreting this finding?

• A. The average socioeconomic status of the study participants.
• B. The specific types of screen activities participants engaged in.
• C. Whether the students had access to healthy meals and snacks.
• D. The participants' ages and grade levels.

Correct answer: B

Rationale: Knowing the specific types of screen activities participants engaged in would provide crucial context for interpreting the link between increased screen time and lower academic performance. For example, if the majority of screen time was spent on educational apps or programs, the impact on academic performance may differ compared to if the screen time was mostly spent on social media or gaming. Understanding the nature of screen activities can help determine the potential mechanisms behind the observed relationship.

4. How many moles of water are produced when 0.5 moles of methane (CH4) react with excess oxygen?

• A. 0.5 moles
• B. 1 mole
• C. 2 moles
• D. 3 moles

Correct answer: c

Rationale: The balanced equation is CH4 + 2O2 → CO2 + 2H2O, indicating a 1:2 ratio between CH4 and H2O.

5. The concept of punctuated equilibrium suggests that:

• A. Evolution occurs gradually through the continuous accumulation of small changes over long periods.
• B. Evolution is characterized by long periods of relative stasis punctuated by rapid bursts of evolutionary change.
• C. The fossil record is a complete and accurate representation of all past life forms.
• D. Natural selection primarily favors extreme phenotypes within a population.

Correct answer: B

Rationale: Rationale: A) Evolution occurs gradually through the continuous accumulation of small changes over long periods - This statement describes the gradualism model of evolution, not punctuated equilibrium. Punctuated equilibrium suggests that evolution is characterized by long periods of little to no change (stasis) followed by relatively rapid bursts of evolutionary change. B) Evolution is characterized by long periods of relative stasis punctuated by rapid bursts of evolutionary change - This statement accurately describes the concept of punctuated equilibrium proposed by Stephen Jay Gould and Niles Eldredge. It suggests that species remain relatively unchanged for long periods of time, interrupted by sudden bursts of rapid evolution. C) The fossil record is a complete and accurate representation of all past life forms - This statement is incorrect as the fossil record is incomplete and biased towards certain types of organisms and environments. It does not provide a complete and accur

6. A nurse administers 150mg of medication every 4 hours. How many milligrams will the patient receive in 24 hours?

• A. 300mg
• B. 600mg
• C. 750mg
• D. 900mg

Correct answer: D

Rationale: Rationale: - The patient receives 150mg of medication every 4 hours. - To calculate how many milligrams the patient will receive in 24 hours, we need to determine how many times the medication is administered in 24 hours. - Since the medication is administered every 4 hours, there are 24 hours in a day, so the medication will be administered 24 / 4 = 6 times in 24 hours. - Therefore, the total amount of medication the patient will receive in 24 hours is 150mg x 6 = 900mg.
