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 Levothyroxine. Which of the following instructions should the nurse include?

• A. Take this medication with food.
• B. Take this medication at bedtime.
• C. Take this medication on an empty stomach.
• D. Take this medication with antacids.

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption, affecting the medication's effectiveness.

3. A client with chronic myeloid leukemia is receiving hydroxyurea. Which of the following findings should the nurse monitor?

• A. Hyperkalemia
• B. Hypertension
• C. Neutropenia
• D. Tinnitus

Correct answer: C

Rationale: The nurse should monitor the client for neutropenia when receiving hydroxyurea. Neutropenia is a common adverse effect caused by bone marrow suppression. It is essential to assess the client's white blood cell count regularly to detect neutropenia early and prevent complications such as infections.

4. A nurse is providing teaching to a client who has a new prescription for Metoprolol. Which of the following statements should the nurse include?

• A. This medication may make you feel dizzy at first.
• B. You should avoid foods that are high in fat.
• C. Take the medication in the morning.
• D. You may experience a rapid heart rate while taking this medication.

Correct answer: A

Rationale: Metoprolol, a beta-blocker, can cause dizziness, especially when starting the medication. The nurse should inform the client to change positions slowly to avoid dizziness and falls.

5. A client has a new prescription for radioactive iodine to treat Hyperthyroidism. Which of the following instructions should the nurse include?

• A. Expect a metallic taste in the mouth.
• B. Avoid contact with pregnant women for 1 week.
• C. Administer iodine solution using a straw.
• D. Take thyroid replacement medication for 3 weeks after treatment.

Correct answer: B

Rationale: When a client undergoes radioactive iodine treatment for hyperthyroidism, they can emit radiation for a short time. To prevent radiation exposure to others, especially pregnant women, infants, and small children, clients should avoid close contact for about 1 week following therapy. This precaution is essential to protect vulnerable individuals from potential harm. Choice A is incorrect because a metallic taste in the mouth is not a common side effect of radioactive iodine treatment. Choice C is incorrect because administering iodine solution using a straw is not a standard practice in this treatment. Choice D is incorrect because taking thyroid replacement medication for 3 weeks after treatment is not a typical instruction associated with radioactive iodine therapy for hyperthyroidism.
