1. Which drug undergoes extensive first-pass hepatic metabolism?

• A. Heparin
• B. Insulin
• C. Propranolol
• D. Nitroglycerin

Correct answer: C

Rationale: Propranolol undergoes extensive first-pass hepatic metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration. Heparin (Choice A) is not metabolized by the liver but excreted unchanged by the kidneys. Insulin (Choice B) is a peptide hormone that is not subject to significant first-pass metabolism. Nitroglycerin (Choice D) is primarily metabolized in the blood and tissues, bypassing significant first-pass metabolism in the liver.

2. A client has a new prescription for Raltegravir. Which of the following statements should the nurse include in teaching the client?

• A. This medication prevents the virus from entering the cell.
• B. This medication prevents the virus from leaving the cell.
• C. This medication blocks the virus from attaching to the cell.
• D. This medication blocks the virus from replicating in the cell.

Correct answer: D

Rationale: The correct answer is D because Raltegravir works by blocking the integrase enzyme, preventing the virus from integrating its genetic material into the host cell's DNA. By inhibiting this process, viral replication within the host cell is halted. Choices A, B, and C are incorrect because Raltegravir's mechanism of action specifically targets viral replication within the cell, not virus entry, exit, or attachment to the cell.

3. A healthcare provider is planning to administer Ciprofloxacin IV to a client who has cystitis. Which of the following actions should the healthcare provider take?

• A. Administer a concentrated solution.
• B. Infuse the medication over 60 min.
• C. Infuse the solution through the primary IV fluid tubing.
• D. Choose a small peripheral vein for administration.

Correct answer: B

Rationale: Ciprofloxacin should be infused over 60 minutes to minimize vein irritation and reduce the risk of adverse effects. Administering a concentrated solution can lead to vein irritation and potential complications. Infusing the solution through the primary IV fluid tubing can cause incompatibility issues. Choosing a small peripheral vein may not be suitable for administering Ciprofloxacin, which should be infused through a larger vein to prevent vein irritation and ensure a proper dilution of the medication.

4. A client with chronic Neutropenia is receiving Filgrastim. What action should the nurse take to assess for an adverse effect of filgrastim?

• A. Assess for bone pain.
• B. Assess for right lower quadrant pain.
• C. Auscultate for crackles in the bases of the lungs.
• D. Auscultate the chest to listen for a heart murmur.

Correct answer: A

Rationale: Bone pain is a known adverse effect of Filgrastim, which is dose-related. By assessing for bone pain, the nurse can monitor for this common side effect. Acetaminophen and, if necessary, an opioid analgesic can be used to manage the bone pain associated with Filgrastim. Assessing for right lower quadrant pain, crackles in the bases of the lungs, or heart murmurs would not directly relate to the adverse effects of Filgrastim in a client with chronic Neutropenia.

5. When teaching a client with a new prescription for Warfarin, which herbal supplement should the nurse instruct the client to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: The correct answer is St. John's wort. St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism, potentially leading to decreased anticoagulant effects. Therefore, the nurse should instruct the client to avoid using St. John's wort while taking Warfarin to prevent adverse drug interactions. Echinacea, garlic, and ginseng are not the correct answers in this case. While these herbal supplements may also interact with Warfarin and affect its efficacy, St. John's wort has a well-known interaction with Warfarin that can significantly impact its anticoagulant effects. Educating the client about the specific interaction between St. John's wort and Warfarin is crucial to ensure patient safety and the medication's therapeutic benefit.
