Nursing Elites

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 receiving chemotherapy reports nausea and vomiting. Which of the following medications should the nurse anticipate administering?

• A. Ondansetron
• B. Metoclopramide
• C. Promethazine
• D. Lorazepam

Correct answer: A

Rationale: The correct answer is A: Ondansetron. Ondansetron is a commonly used antiemetic for managing nausea and vomiting in clients undergoing chemotherapy. It works by blocking serotonin to reduce these symptoms effectively. Metoclopramide (choice B) is another antiemetic but is more commonly used for gastric motility disorders. Promethazine (choice C) is an antihistamine with antiemetic properties, but ondansetron is often preferred for chemotherapy-induced nausea and vomiting due to its efficacy and fewer side effects. Lorazepam (choice D) is a benzodiazepine used for anxiety and insomnia, not typically for managing nausea and vomiting in this context.

3. A client has a new prescription for Metformin. Which of the following instructions should be included?

• A. Take this medication with food.
• B. Avoid eating foods high in potassium.
• C. Take this medication at bedtime.
• D. Take this medication every other day.

Correct answer: A

Rationale: The correct instruction for taking Metformin is to take it with food. This helps reduce gastrointestinal side effects and ensures better absorption of the medication. Choice B is incorrect as there is no specific need to avoid foods high in potassium when taking Metformin. Choice C is incorrect because Metformin is usually taken with meals, not at bedtime. Choice D is incorrect as Metformin is typically taken daily, not every other day.

4. A client has a new prescription for Lisinopril. Which of the following laboratory values should be monitored?

• A. Serum potassium
• B. Serum sodium
• C. Serum calcium
• D. Serum magnesium

Correct answer: A

Rationale: Corrected Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing potassium excretion through the kidneys. Monitoring serum potassium levels is crucial to detect hyperkalemia early and prevent adverse effects such as cardiac arrhythmias. Choices B, C, and D are incorrect because Lisinopril is not known to significantly impact sodium, calcium, or magnesium levels in the same way it affects potassium levels.

5. A client is reviewing a new prescription for Terbutaline with a history of preterm labor. Which of the following client statements indicates understanding of the teaching?

• A. I can increase my activity now that I've started on this medication.
• B. I will increase my daily fluid intake to 3 quarts.
• C. I will report increasing intensity of contractions to my doctor.
• D. I am glad this will prevent preterm labor.

Correct answer: C

Rationale: The correct answer is C. The client should report increasing intensity, frequency, or duration of contractions to the provider as these are signs of preterm labor. Monitoring contractions is crucial for the management of preterm labor and the safety of both the client and the fetus. Choices A, B, and D are incorrect because increasing activity, fluid intake, or assuming the medication will prevent preterm labor do not address the essential need to report changes in contractions, which are a vital sign of potential complications in preterm labor.
