Morphine acts as an agonist on the mu and kappa receptors.

Morphine is only used to prevent fevers.
The Correct Answer is B
Choice A rationale
Morphine has a high potential for abuse due to its euphoric effects and the risk of developing physical dependence and addiction with prolonged use.
Choice B rationale
Morphine acts as an agonist on the mu and kappa receptors in the central nervous system, providing analgesic effects by altering the perception of and response to pain.
Choice C rationale
Morphine is a potent analgesic that is more effective than butorphanol, which is a mixed agonist-antagonist with less potency and a ceiling effect on pain relief.

Morphine is primarily used for pain management and is not indicated for preventing fevers.

Correct Answer is D
Explanation
Choice A rationale
Aspiration is not recommended for subcutaneous injections because it can increase tissue damage and pain. Enoxaparin should be administered without aspiration.
Choice B rationale
Prefilled syringes of enoxaparin contain an air bubble to ensure the entire dose is administered. Expelling the air bubble before injection is not recommended.
Choice C rationale
Enoxaparin should be administered in the abdomen, at least 2 inches away from the umbilicus, to ensure proper absorption and effectiveness.
Choice D rationale
Enoxaparin should be administered subcutaneously, and the needle should be inserted completely to ensure the medication is delivered into the subcutaneous tissue.
Correct Answer is D
Explanation
Choice A rationale
Tumor enhancer genes are not typically a recognized category in cancer genetics. Proto-oncogenes and DNA repair genes are relevant to cancer development.
Choice B rationale
This choice is incorrect as there are genes like proto-oncogenes, tumor suppressor genes, and DNA repair genes that play roles in cancer.
Choice C rationale
This choice is partially correct but incomplete without including DNA repair genes, which are also crucial in cancer prevention.
Choice D rationale
This choice is correct as proto-oncogenes can become oncogenes, tumor suppressor genes prevent uncontrolled cell growth, and DNA repair genes fix DNA mutations that can lead to cancer.
