Nursing Elites

1. A client has a new prescription for Warfarin. Which of the following herbal supplements should the client be instructed to avoid?

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

Correct answer: A

Rationale: St. John's wort should be avoided by clients taking Warfarin as it can reduce the medication's effectiveness by affecting its metabolism. Echinacea, garlic, and ginseng are also known to interact with Warfarin, either by increasing the risk of bleeding or altering its anticoagulant effects. However, St. John's wort is particularly significant due to its potent enzyme-inducing properties that can lead to subtherapeutic levels of Warfarin, potentially increasing the risk of blood clots.

2. A healthcare professional is preparing to administer clindamycin 200 mg by intermittent IV bolus. The amount available is clindamycin injection 200 mg in 100 mL 0.9% sodium chloride (0.9% NaCl) to infuse over 30 min. The healthcare professional should set the IV pump to deliver how many mL/hr?

• A. 200 mL/hr
• B. 150 mL/hr
• C. 100 mL/hr
• D. 250 mL/hr

Correct answer: A

Rationale: To calculate the flow rate in mL/hr: (Volume in mL / Time in hours) = Flow rate in mL/hr. In this case, (100 mL / 0.5 hr) = 200 mL/hr. The correct calculation is: 100 mL (volume) / 0.5 hr (time) = 200 mL/hr. Therefore, the correct answer is 200 mL/hr. Choice B (150 mL/hr), C (100 mL/hr), and D (250 mL/hr) are incorrect as they do not match the calculated flow rate needed for the administration of clindamycin.

3. A nurse is teaching a client who has a new prescription for Prednisone. Which of the following instructions should the nurse include?

• A. Increase your intake of vitamin
• B. Take this medication on an empty stomach.
• C. Avoid drinking grapefruit juice.
• D. Take this medication every other day.

Correct answer: A

Rationale: Prednisone can lead to bone loss, so clients should increase their intake of vitamin D and calcium to help maintain bone health.

4. A client has a prescription for Nitroglycerin, and a nurse is providing teaching. Which of the following instructions should the nurse include?

• A. Take one tablet every 15 minutes until pain is relieved.
• B. Take one tablet every 5 minutes, up to three doses.
• C. Take one tablet at bedtime.
• D. Take one tablet on an empty stomach.

Correct answer: B

Rationale: The correct instruction for taking Nitroglycerin is to take one tablet at the onset of chest pain, then repeat every 5 minutes for up to three doses. Option A is incorrect because taking a tablet every 15 minutes until pain is relieved may lead to delayed intervention. Option C is incorrect as taking Nitroglycerin at bedtime is not indicated for chest pain. Option D is incorrect as Nitroglycerin should be taken sublingually at the onset of chest pain, not on an empty stomach.

5. A client is prescribed an IM dose of penicillin. The client reports developing a rash after taking penicillin 3 years ago. What should the nurse do?

• A. Administer the prescribed dose.
• B. Withhold the medication.
• C. Ask the provider to change the prescription to an oral form.
• D. Administer an oral antihistamine at the same time.

Correct answer: B

Rationale: The nurse should withhold the medication and inform the provider of the client's previous rash after taking penicillin. This history suggests a potential allergic reaction to penicillin, which can range from mild to severe anaphylaxis. Notifying the provider allows for an alternative antibiotic to be prescribed, considering the client's allergy to penicillin. It is crucial to avoid administering a medication that could potentially lead to a severe allergic reaction in the client. Administering the prescribed dose (Choice A) could be harmful due to the potential for an allergic reaction. Changing the prescription to an oral form (Choice C) does not address the underlying issue of a potential penicillin allergy. Administering an oral antihistamine (Choice D) without consulting the provider may not be sufficient to prevent a severe allergic reaction.
