A nurse is preparing to administer a medication and learns that it is a nonselective agonist. What does the nurse understand about this drug?

It directly activates receptors to affect a specific physiologic process.

It prevents receptor activation to affect a specific physiologic process.

It directly activates receptors to affect many physiologic processes.

It prevents receptor activation to affect many physiologic processes.

Answer and Explanation

The Correct Answer is C

Choice A reason: Nonselective agonists activate multiple receptors, not specific ones, leading to widespread effects. Specific processes are targeted by selective agonists, so this is incorrect for nonselective drugs.

Choice B reason: Nonselective agonists activate, not prevent, receptors. Prevention is the role of antagonists, so this is incorrect for a nonselective agonist’s mechanism of action.

Choice C reason: Nonselective agonists activate multiple receptor types, affecting many physiologic processes (e.g., epinephrine). This broad action is their hallmark, making it the correct choice for the drug’s effect.

Choice D reason: Preventing receptor activation describes antagonists, not agonists. Nonselective agonists stimulate multiple processes, so this is incorrect for the drug’s pharmacological action.

Correct Answer is C

Explanation

Choice A reason: Pentazocine is less effective for severe, chronic pain and has mixed agonist-antagonist effects. Fentanyl is stronger for opioid-tolerant patients, so this is incorrect.

Choice B reason: Hydrocodone is weaker than oxycodone and inadequate for severe, resistant pain. Fentanyl’s potency suits chronic cancer pain, so this is incorrect.

Choice C reason: Fentanyl transdermal is potent, long-acting, and ideal for severe, chronic cancer pain in opioid-tolerant patients. It’s appropriate here, making it the correct choice.

Choice D reason: Meperidine is not recommended for chronic pain due to neurotoxic metabolites. Fentanyl is safer and more effective, so this is incorrect.

A. Respiratory Acidosis B. Metabolic Acidosis C. Metabolic Alkalosis D. Respiratory Alkalosis

Correct Answer is D

Explanation

Choice A reason: Respiratory acidosis has low pH and high PaCO2. High pH (7.47) and low PaCO2 (32) indicate alkalosis, not acidosis, so this incorrect.

Choice B reason: Metabolic acidosis has low pH and HCO3-. High pH and normal HCO3- (23) rule this out, pointing to respiratory alkalosis, so this is incorrect.

Choice C reason: Metabolic alkalosis has high pH and high HCO3-.. Normal HCO3- and low PaCO2 indicate respiratory alkalosis, so this is incorrect.

Choice D reason: High pH (7.47) and low PaCO2 (32) with normal CO2 HCO3- confirm respiratory alkalosis due to hyperventilation. This is matches, so it’s correct.
