Drugs Affecting the Female Reproductive System Quizlet Exam Questions
Question 1 of 5
The drug Zolpidem is classified as a
Correct Answer: A
Rationale: The correct answer is A: Sedative-hypnotic. Zolpidem is used to treat insomnia by promoting sleep onset and improving sleep maintenance. It acts on the central nervous system to enhance the inhibitory neurotransmitter GABA. This classification is based on its pharmacological effects and mechanism of action. B: Anti-anxiety drug - Zolpidem is not primarily indicated for anxiety disorders but for insomnia. C: Anti-convulsant - Zolpidem is not used to prevent or control seizures, so it is not classified as an anti-convulsant. D: Muscle relaxant - Zolpidem does not have a direct effect on muscle relaxation, so it is not classified as a muscle relaxant.
Question 2 of 5
Half-life (t1/2) is the time required to:
Correct Answer: A
Rationale: The correct answer is A because half-life is the time taken for the concentration of a drug in the plasma to decrease by 50%. This is a measure of the rate of elimination of a drug from the body. Choice B is incorrect because half-life does not specifically refer to metabolism. Choice C is incorrect because absorption is not related to half-life. Choice D is incorrect because half-life is not about binding to plasma proteins but about elimination from the body.
Question 3 of 5
All of the following statements related to the binding of drugs by plasma proteins are correct EXCEPT:
Correct Answer: D
Rationale: The correct answer is D because bound drug is not the pharmacologically active part of the drug. The active form of a drug is the unbound fraction that can exert its pharmacological effects. When a drug is bound to plasma proteins, it is unable to exert its pharmacological action until it becomes unbound. Choice A is true because bound drug cannot diffuse into tissues. Choice B is correct because binding to plasma proteins decreases the apparent volume of distribution. Choice C is also true as displacement of bound drug can lead to increased effects of the drug due to increased free drug concentration.
Question 4 of 5
If a drug is eliminated by first-order kinetics, what remains constant?
Correct Answer: B
Rationale: First-order kinetics means the rate of drug elimination is proportional to the drug concentration. Clearance (choice B) represents the volume of plasma cleared of the drug per unit time, which remains constant in first-order kinetics. The other choices are incorrect because: A: In first-order kinetics, the amount of drug eliminated per unit time decreases as drug concentration decreases. C: The elimination half-life is independent of dose in first-order kinetics. D: Complete elimination within two half-lives is a general rule but not specific to first-order kinetics.
Question 5 of 5
The nurse is teaching a pregnant client how to decrease the gastrointestinal distress she experiences with prenatal vitamins. Which instruction would the nurse provide?
Correct Answer: B
Rationale: The correct answer is B: Eat when she takes her vitamins. This is because taking prenatal vitamins on an empty stomach can lead to gastrointestinal distress. Eating food along with the vitamins can help reduce the chances of nausea and other digestive issues. Choice A is incorrect as taking vitamins between meals may worsen gastrointestinal distress. Choice C, drinking orange juice, is incorrect as the acidity of the juice may exacerbate the stomach issues. Choice D, drinking milk, is also incorrect as dairy products can sometimes aggravate gastrointestinal problems. Eating a small snack or meal when taking prenatal vitamins is the most effective way to reduce discomfort.
