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 healthcare professional is planning to administer subcutaneous enoxaparin 40 mg using a prefilled syringe of Enoxaparin 40 mg/0.4 mL to an adult client following hip arthroplasty. Which of the following actions should the healthcare professional plan to take?

• A. Expel the air bubble from the prefilled syringe before injecting.
• B. Insert the needle completely into the client's tissue.
• C. Administer the injection in the client's thigh.
• D. Aspirate carefully after inserting the needle into the client's skin.

Correct answer: B

Rationale: Correct Answer: B. When administering enoxaparin, it is essential to insert the needle completely into the client's tissue to ensure a deep subcutaneous injection. This method helps in the appropriate delivery of the medication. Choice A is incorrect because expelling air bubbles is not necessary with subcutaneous injections and may lead to medication loss. Choice C is incorrect as enoxaparin is usually administered in the abdomen, not the thigh. Choice D is incorrect as aspiration is not recommended for subcutaneous injections to avoid trauma or bleeding.

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

• A. Discontinue the medication if you experience dry mouth.
• B. Take the medication at the same time each day.
• C. Double the dose if you miss a dose.
• D. Avoid drinking orange juice while taking this medication.

Correct answer: B

Rationale: Correct Answer: Taking Clonidine at the same time each day is crucial to ensure consistent blood levels and effectively manage blood pressure. Consistency in timing helps optimize the medication's effectiveness in controlling hypertension.

4. A client is receiving treatment with vincristine. Which of the following findings should the nurse monitor?

• A. Hyperkalemia
• B. Neurotoxicity
• C. Neutropenia
• D. Bradycardia

Correct answer: B

Rationale: The correct answer is B: Neurotoxicity. Vincristine is known to cause neurotoxicity as an adverse effect due to its impact on the nervous system. Monitoring for neurotoxicity is crucial to detect any signs early. Choices A, C, and D are incorrect. Hyperkalemia is not a typical finding associated with vincristine. Neutropenia is a common side effect of chemotherapy but is not directly related to vincristine. Bradycardia is not a common adverse effect of vincristine.

5. What is one therapeutic use for nitroglycerin?

• A. Relief or prevention of anginal attacks
• B. Diuresis and mobilization of excess fluid
• C. Decreasing nausea and vomiting
• D. Relief of anxiety

Correct answer: A

Rationale: Nitroglycerin is primarily used for the relief or prevention of anginal attacks. It works by dilating blood vessels, increasing blood flow and oxygen to the heart muscle, thereby relieving chest pain caused by angina. The medication is not indicated for diuresis, antiemetic effects, or anxiety relief. Therefore, choices B, C, and D are incorrect as they do not reflect the therapeutic use of nitroglycerin.
