Question 1 of 5

A researcher wants to conduct qualitative research. Which method should they use?

Correct Answer: A

Rationale: The correct answer is A: Collecting patient narratives. Qualitative research aims to understand individuals' experiences and perceptions in-depth. Collecting patient narratives allows for capturing subjective insights, emotions, and personal perspectives. This method helps uncover themes, patterns, and nuances in participants' stories, providing rich data for analysis. B: Tracking drug dosage and blood levels is quantitative research, focusing on numerical data. C: Observing physical changes is more suitable for quantitative or observational research. D: Writing journal notes about the research experience is reflective and may provide insights but does not capture the essence of qualitative research, which is to explore subjective experiences.

Question 2 of 5

What is the best tool to measure the volume of a solid?

Correct Answer: C

Rationale: The correct answer is C: Graduated cylinder. To measure the volume of a solid accurately, we need to use a container with volume markings like a graduated cylinder. Step 1: Fill the graduated cylinder with a known amount of water. Step 2: Drop the solid into the water and measure the new water level. Step 3: Subtract the initial water level from the final level to find the volume displaced, which is the volume of the solid. The other choices are incorrect because a triple beam balance measures mass, a measuring wheel is for linear measurements, and using a measuring wheel and formula may not provide accurate volume measurements.

Question 3 of 5

Which of the following is a function of the large intestine?

Correct Answer: D

Rationale: The correct answer is D: All of the above. The large intestine plays a crucial role in absorbing water to form solid waste (A). It also houses beneficial bacteria that produce vitamin K, essential for blood clotting and bone health (B). Additionally, the large intestine is involved in the absorption of some vitamin B compounds produced by gut bacteria (C). Thus, all the functions listed (A, B, C) are carried out by the large intestine. Other choices are incorrect because they do not encompass all the functions performed by the large intestine.

Question 4 of 5

What does the P-wave in an ECG correspond to?

Correct Answer: B

Rationale: The correct answer is B: Depolarization of the SA node. The P-wave in an ECG represents atrial depolarization, which is initiated by the SA node. This electrical signal spreads through the atria causing them to contract. Choice A is incorrect because the P-wave corresponds to atrial depolarization, not repolarization. Choice C is incorrect as the QRS complex represents ventricular depolarization. Choice D is incorrect as the T-wave represents ventricular repolarization. Therefore, the SA node depolarization is accurately represented by the P-wave in an ECG.

Question 5 of 5

What is the name of the long bone found in the upper arm?

Correct Answer: C

Rationale: The correct answer is C: Humerus. The humerus is the long bone found in the upper arm. It connects the shoulder to the elbow joint. The femur (A) is the long bone found in the thigh, the tibia (B) is the larger of the two lower leg bones, and the radius (D) is one of the two lower arm bones. The humerus is the only bone among the choices that is specifically located in the upper arm, making it the correct answer.
