1. What is pharmacodynamics?
- A. The medical reference summarizing standards of drug purity, strength, and directions for synthesis
- B. The drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions
- C. The maximum response that a drug can produce
- D. Movements of the drugs throughout the body
Correct answer: B
Rationale: Pharmacodynamics refers to the drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions. It involves understanding how drugs interact with the body at the molecular level to produce their effects, including mechanisms of action, receptor binding, and downstream physiological responses. Choice A is incorrect because it describes pharmacopeia, which is a reference book containing standards for drugs. Choice C refers to efficacy, which is the maximum effect a drug can produce. Choice D describes pharmacokinetics, which focuses on the movement of drugs within the body.
2. A client is taking Glipizide to treat Diabetes Mellitus. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of this medication?
- A. Cholesterol level.
- B. Hematocrit.
- C. Blood glucose level.
- D. Calcium level.
Correct answer: C
Rationale: The correct answer is C: Blood glucose level. Monitoring the client's blood glucose level is crucial when taking Glipizide, a medication used to lower blood glucose levels in individuals with Diabetes Mellitus. By monitoring the blood glucose level, the nurse can evaluate the effectiveness of the medication in managing the client's condition. Choices A, B, and D are incorrect as they are not directly related to assessing the effectiveness of Glipizide in treating Diabetes Mellitus. Cholesterol level, hematocrit, and calcium level may be important for other aspects of the client's health but are not the primary indicators of Glipizide's effectiveness.
3. A client has a new prescription for alendronate to treat osteoporosis. Which of the following instructions should be included in the teaching?
- A. Take the medication with a full glass of water after rising in the morning.
- B. Lie down for 30 minutes after taking the medication.
- C. Take the medication with a meal to reduce gastric irritation.
- D. Crush the tablet and mix it with applesauce if difficulty swallowing.
Correct answer: A
Rationale: The correct instruction for taking alendronate is to take it with a full glass of water after rising in the morning to prevent esophageal irritation. It is important to remain upright for at least 30 minutes after taking the medication to reduce the risk of esophageal irritation and ensure proper absorption. Taking the medication with a meal or crushing the tablet are not recommended instructions for alendronate administration. Choice A is the correct answer as it aligns with the proper administration guidelines for alendronate.
4. A client has been prescribed Prednisone for asthma. Which of the following instructions should the nurse include in the teaching?
- A. Take this medication with food to prevent nausea.
- B. Take this medication at bedtime to reduce drowsiness.
- C. Take this medication in the morning to reduce insomnia.
- D. Avoid sudden changes in position.
Correct answer: C
Rationale: Prednisone is best taken in the morning to reduce the risk of insomnia, a common side effect of corticosteroids. Instructing the client to take the medication in the morning aligns with the goal of minimizing the impact of insomnia, which can disrupt sleep patterns and affect overall well-being. Choices A, B, and D are incorrect. Taking Prednisone with food does not primarily focus on preventing nausea; taking it at bedtime does not primarily reduce drowsiness, and avoiding sudden changes in position is not a specific instruction related to Prednisone use for asthma.
5. A client has a prescription for digoxin. The client should be monitored for which of the following findings as an indication of digoxin toxicity?
- A. Visual disturbances
- B. Tachycardia
- C. Increased appetite
- D. Constipation
Correct answer: A
Rationale: Visual disturbances, such as yellow-tinged vision or seeing halos around lights, are common signs of digoxin toxicity. These symptoms should be reported immediately to healthcare providers for further evaluation and management. Tachycardia (Choice B) is not typically associated with digoxin toxicity. Increased appetite (Choice C) and constipation (Choice D) are not common manifestations of digoxin toxicity. Therefore, the correct answer is visual disturbances.
