Question 1 of 5

The reason for using Taq polymerase for PCR is that

A. it has regions that are complementary to primers. B. only minute amounts are needed for each cycle of PCR C. it binds more readily than other polymerases to primer. D. it is heat stable and can withstand the temperature changes of the cycler.

Correct Answer: D

Rationale: The correct answer is D because Taq polymerase is heat-stable, allowing it to withstand the high temperatures used in PCR cycles without denaturing. This heat stability is crucial for the repeated heating and cooling cycles in PCR. Choice A is incorrect because Taq polymerase does not need to be complementary to primers. Choice B is incorrect because the amount needed is not the main reason for using Taq polymerase. Choice C is incorrect because binding affinity to primers is not the primary reason for using Taq polymerase.

A. Assess patients’ nutritional needs and individualize diet plans to improve nutrition. B. Collect data about the patients’ response to medications used for pain and anorexia. C. Teach the nursing assistants about how to lower the risk for spreading infections. D. Assist patients with personal hygiene and other activities of daily living as needed.

Correct Answer: B

Rationale: LPNs are trained to collect data and monitor patients’ responses to medications which is within their scope of practice. Assessing nutritional needs and teaching about infection control are more complex tasks that typically require the expertise of an RN. Assisting with personal hygiene is usually delegated to nursing assistants.
