Nursing Elites

1. The physician orders the antibiotics ampicillin (Omnipen) and gentamicin (Garamycin) for a newly admitted client with an infection. The nurse should:

• A. administer both medications simultaneously.
• B. give the medications sequentially, and flush well between them.
• C. ask the physician or pharmacy which medication to give first and how long to wait before giving the other drug.
• D. start one medication now and begin the other medication in 2-4 hours.

Correct answer: B

Rationale: A client with an infection needs both antibiotics as soon as possible. However, the pH of ampicillin is 8-10, and the pH of gentamicin is 3-5.5, making them incompatible when given together. Flushing well between drugs is necessary to prevent interaction. Choice C is incorrect because the nurse, not the physician or pharmacy, should determine the correct administration sequence. Consulting with the pharmacist is appropriate if uncertain. Choice D is incorrect because delaying the second medication by several hours can slow the treatment of the client's infection, as both antibiotics are needed promptly to address the infection effectively. Therefore, the correct action is to give the medications sequentially and flush well between them to prevent any potential interactions.

2. A client with acute leukemia develops a low white blood cell count. In addition to the institution of isolation, the nurse should:

• A. Request that foods be provided in sealed single-serving packages
• B. Ask the client to wear a mask when visitors are present
• C. Prep IV sites with mild soap and water and alcohol
• D. Provide foods in sealed single-serving packages

Correct answer: D

Rationale: For a client with acute leukemia and a low white blood cell count, preventing exposure to food contaminants is crucial due to immune suppression. Providing foods in sealed single-serving packages helps reduce the risk of contamination. Choice B is incorrect as it introduces the potential of infection from visitors. Choice A, suggesting disposable utensils, is not as effective as sealed containers in preventing food contamination. Choice C, using alcohol for prepping IV sites, is less suitable due to its drying effect and potential for skin breakdown, making sealed packages a better option for food safety.

3. The doctor orders 2% nitroglycerin ointment in a 1-inch dose every 12 hours. Proper application of nitroglycerin ointment includes:

• A. Rotating application sites
• B. Limiting applications to the chest
• C. Rubbing it into the skin
• D. Covering it with a thin paper dressing

Correct answer: A

Rationale: Proper application of nitroglycerin ointment involves rotating application sites to prevent skin irritation. It should be applied to the back and upper arms, not restricted to the chest, making option B incorrect. Rubbing it into the skin, as indicated in option C, is not recommended for nitroglycerin ointment as it can lead to faster absorption and potential side effects. The correct way is to cover it with a thin paper dressing, not gauze as mentioned in option D, to ensure proper absorption and prevent the medication from evaporating too quickly.

4. A client in the cardiac step-down unit requires suctioning for excess mucous secretions. The nurse should be most careful to monitor the client for which dysrhythmia during this procedure?

• A. Bradycardia
• B. Tachycardia
• C. Premature ventricular beats
• D. Heart block

Correct answer: A

Rationale: During suctioning, a vagal response can be triggered leading to bradycardia. It is crucial for the nurse to monitor for this potential dysrhythmia. Tachycardia (Choice B) is less likely during suctioning and is not the priority. Premature ventricular beats (Choice C) and heart block (Choice D) can occur but are less common compared to bradycardia in this situation.

5. Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?

• A. They have a high energy-to-fluid-volume ratio.
• B. Even though hypertonic, they are well tolerated.
• C. They are a basic solution due to the addition of sodium hydroxide (NaOH).
• D. The pH is alkaline, making them compatible with most medications.

Correct answer: A

Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.
