The client receives estrogen for prostate cancer. He asks the nurse why he is receiving a female hormone. What is the best response by the nurse?

Correct Answer: C

Rationale: Estrogen suppresses androgen production , starving androgen-dependent prostate cancer. Choice A misstates cell death. Choice B overstates testosterone elimination. Choice D misattributes nutrient blockade. C explains the hormonal mechanism accurately, making it the best response.

Correct Answer: D

Rationale: Acetaminophen is not an opioid or NSAID. While it is commonly used to relieve pain and reduce fever, acetaminophen works differently from opioids and NSAIDs. Acetaminophen is believed to reduce pain by inhibiting the production of prostaglandins in the brain, whereas opioids work by binding to opioid receptors in the central nervous system, and NSAIDs work by inhibiting the production of prostaglandins in the peripheral tissues.

Correct Answer: C

Rationale: Estrogen suppresses androgen production , starving androgen-dependent prostate cancer. Choice A misstates cell death. Choice B overstates testosterone elimination. Choice D misattributes nutrient blockade. C explains the hormonal mechanism accurately, making it the best response.

Correct Answer: B

Rationale: Pharmacodynamics refers to the study of the biochemical, physiological, and behavioral effects of drugs on the body and their mechanisms of action. It specifically focuses on the drugs' actions at the receptor site and how these actions lead to specific responses in the body. This includes understanding how drugs interact with target receptors, enzymes, and other molecular targets within the body to produce their effects. Pharmacodynamics also involves studying the relationship between the drug concentration and the magnitude of the response it elicits, as well as factors influencing the variability in individual responses to a drug. In summary, pharmacodynamics is crucial for understanding how drugs work in the body and how they produce their therapeutic or adverse effects.

Correct Answer: D

Rationale: Drowsiness is a common side effect of oxycodone, an opioid analgesic. Patients should be advised to avoid activities requiring alertness, such as driving, while taking this medication. Paresthesia (A), increased intracranial pressure (B), and occipital headache (C) are not typical side effects of oxycodone.
