1. A study finds a link between increased sugar intake and obesity. Does this confirm sugar causes obesity?

• A. Yes, the study definitively proves causation.
• B. No, correlation does not equal causation, other factors might be involved.
• C. We need more research to isolate the specific role of sugar.
• D. This only applies to people with genetic predispositions to obesity.

Correct answer: C

Rationale: Correlation suggests a link, but other factors might contribute. Further research is needed to establish the direction and strength of any causal relationship.

2. A table shows the average blood pressure readings for different age groups. How do you determine the highest average systolic pressure?

• A. Find the largest number in the "systolic pressure" column.
• B. Compare the means (averages) of each age group.
• C. Add all systolic pressure values and divide by the total number of patients.
• D. Subtract the lowest systolic pressure from the highest.

Correct answer: A

Rationale: Rationale: - To determine the highest average systolic pressure, you need to identify the highest individual systolic pressure reading in the dataset. - Option A instructs you to find the largest number in the "systolic pressure" column, which directly addresses the task of identifying the highest systolic pressure reading. - Comparing means (Option B) would not necessarily give you the highest individual systolic pressure reading, as averages can be influenced by the distribution of values within each age group. - Adding all systolic pressure values and dividing by the total number of patients (Option C) would give you the overall average systolic pressure, not the highest individual reading. - Subtracting the lowest systolic pressure from the highest (Option D) would give you the range of systolic pressures, not specifically the highest individual reading. Therefore, the correct approach to determine the highest average systolic pressure

3. Ms. Valencia prepares the process standards. Which of the following is NOT a process

• A. Initial assessment shall be done to all patients within twenty four hours upon admission.
• B. Informed consent shall be secured prior to any invasive procedure
• C. Patients’ reports 95% satisfaction rate prior to discharge from the hospital.
• D. Patient education about their illness and treatment shall be provided for all patients and their

Correct answer: D

Rationale: In this question, Ms. Valencia is tasked with preparing process standards, which are systematic procedures or steps followed to ensure quality care. Options A, B, and C all refer to specific processes that are essential in healthcare: timely assessment, obtaining informed consent, and assessing patient satisfaction. However, option D about providing patient education is more focused on an outcome (patient education) rather than a specific process standard. While patient education is important, the question is asking for a process standard, making option D the correct answer as it does not directly relate to a specific process standard.

4. Which of the following terms refers to the degeneration of nerve tissue?

• A. Potentiation
• B. Demyelination
• C. Reuptake
• D. Neurogenesis

Correct answer: B

Rationale: The correct answer is B: 'Demyelination.' Demyelination is the term used to describe the degeneration of the myelin sheath, the protective covering of nerve fibers. This process can lead to impaired nerve signal transmission and potential nerve damage. 'Potentiation' refers to the strengthening of neural connections, 'Reuptake' is the reabsorption of neurotransmitters by the presynaptic neuron, and 'Neurogenesis' is the generation of new nerve cells. In this context, demyelination is the most appropriate term related to nerve tissue degeneration.

5. 7 is divisible by which of the following numbers?

• A. 2 only
• B. 3 only
• C. 1 and 7 only
• D. 2, 3, and 7

Correct answer: D

Rationale: Rationale: 1. 7 is divisible by 1 because every number is divisible by 1. 2. 7 is divisible by 7 because any number is divisible by itself. 3. 7 is not divisible by 2 because 7 is an odd number and not divisible by 2. 4. 7 is not divisible by 3 because the sum of the digits of 7 (7) is not divisible by 3. Therefore, 7 is divisible by 1, 7, and itself (7), making the correct answer D) 2, 3, and 7.

6. What is the name of the muscular ring that controls the passage of food from the esophagus to the stomach?

• A. Pyloric sphincter
• B. Cardiac sphincter
• C. Ileocecal valve
• D. Sphincter of Oddi

Correct answer: B

Rationale: The correct answer is B: Cardiac sphincter. The cardiac sphincter, also known as the lower esophageal sphincter, is the muscular ring located at the junction between the esophagus and the stomach. It controls the passage of food from the esophagus into the stomach by opening and closing to prevent reflux of stomach contents back into the esophagus. The other options are incorrect: A) The pyloric sphincter is located at the junction between the stomach and the small intestine, controlling the passage of food from the stomach into the small intestine. C) The ileocecal valve is located between the small intestine and the large intestine. D) The Sphincter of Oddi is located in the duodenum and regulates the flow of bile and pancreatic juice into the small intestine. Therefore, the correct answer is B because it specifically relates to the passage of food from the esophagus to the stomach.
