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 has a new prescription for Hydralazine. Which of the following adverse effects should the nurse instruct the client to monitor?

• A. Tachycardia
• B. Hyperglycemia
• C. Hyponatremia
• D. Constipation

Correct answer: A

Rationale: Corrected Rationale: Hydralazine is a vasodilator that can cause reflex tachycardia as an adverse effect. The client should monitor their pulse and report any significant increases, as tachycardia can indicate a severe adverse reaction to the medication. Choice B, Hyperglycemia, is not a common adverse effect of Hydralazine. Choice C, Hyponatremia, and Choice D, Constipation, are also not typically associated with Hydralazine use. Therefore, the correct answer is A: Tachycardia.

3. A client has a new prescription for clonidine to treat hypertension. Which of the following instructions should the nurse include?

• A. Discontinue the medication if a rash develops.
• B. Expect increased salivation during the first few weeks of therapy.
• C. Avoid driving until the client's reaction to the medication is known.
• D. Stop the medication if you experience a dry mouth.

Correct answer: C

Rationale: The correct instruction for a client starting clonidine therapy for hypertension is to avoid driving until their reaction to the medication is known. Clonidine can cause drowsiness, so it is important for the client to refrain from activities that require alertness until they are aware of how the medication affects them. Choice A is incorrect because a rash is not a common side effect of clonidine. Choice B is incorrect as increased salivation is not an expected side effect of clonidine. Choice D is also incorrect as dry mouth is a common side effect of clonidine, but it is not a reason to stop the medication unless severe or bothersome. Therefore, the priority instruction for the nurse to include is to advise the client to avoid driving until their reaction to the medication is known to ensure safety.

4. A client has a new prescription for Phenelzine for the treatment of depression. Which of the following indicates that the client has developed an adverse effect of this medication?

• A. Orthostatic hypotension
• B. Hearing loss
• C. Gastrointestinal bleeding
• D. Weight loss

Correct answer: A

Rationale: Orthostatic hypotension is a known adverse effect of MAOIs, such as Phenelzine. It is characterized by a drop in blood pressure upon standing, which can lead to dizziness or fainting. Monitoring for orthostatic hypotension is crucial when administering MAOIs to prevent potential complications. Hearing loss (Choice B) is not a typical adverse effect associated with Phenelzine. Gastrointestinal bleeding (Choice C) is more commonly linked to NSAIDs or anticoagulants. Weight loss (Choice D) is not a typical adverse effect of Phenelzine and is more likely related to other factors such as appetite changes or metabolic issues.

5. A client has a new prescription for Ranitidine to treat peptic ulcer disease. Which of the following instructions should the nurse include?

• A. Take the medication on an empty stomach.
• B. Avoid smoking while taking this medication.
• C. Increase intake of dairy products.
• D. Expect a yellow tinge to the skin.

Correct answer: B

Rationale: The correct instruction that the nurse should include for a client prescribed Ranitidine to treat peptic ulcer disease is to avoid smoking while taking the medication. Smoking can interfere with the effectiveness of ranitidine and worsen ulcer symptoms. Therefore, it is crucial for clients to abstain from smoking to ensure optimal therapeutic outcomes. Choices A, C, and D are incorrect. Taking Ranitidine with or without food does not significantly affect its effectiveness, there is no specific need to increase intake of dairy products, and expecting a yellow tinge to the skin is not a common side effect associated with Ranitidine.
