Nursing Elites

1. When obtaining a urine specimen for a culture and sensitivity from an indwelling catheter, the nurse should:

• A. Cleanse the entry port prior to withdrawing urine.
• B. Use a sterile syringe to collect urine from the collection bag.
• C. Obtain the specimen from the drainage tubing.
• D. Replace the catheter before obtaining the specimen.

Correct answer: A

Rationale: The correct procedure when obtaining a urine specimen from an indwelling catheter for culture and sensitivity is to cleanse the entry port before withdrawing urine. This step helps reduce the risk of contamination and ensures the accuracy of the results. Option B is incorrect because using a sterile syringe to collect urine from the collection bag is not the recommended method for obtaining a catheter specimen. Option C is incorrect as obtaining the specimen from the drainage tubing is not the appropriate technique for collecting a urine sample from an indwelling catheter. Option D is incorrect because replacing the catheter before obtaining the specimen is not necessary and may introduce unnecessary complications.

2. A client in a provider’s office tells the nurse that, 'I fast for several days each week to help control my weight.' The client takes several medications for various chronic issues. The nurse should explain to the client that which of the following mechanisms that result from fasting puts her at risk for medication toxicity?

• A. Increasing the metabolism of the medications over time
• B. Increasing the protein-binding response
• C. Increasing medications’ transit time through the intestines
• D. Decreasing the excretion of medications

Correct answer: B

Rationale: Fasting can lead to an increased protein-binding response of medications. This can result in a higher concentration of bound medications in the bloodstream, potentially causing toxicity as the medications may not be readily available for metabolism or excretion. Choice A is incorrect because fasting typically doesn't increase medication metabolism. Choice C is incorrect as fasting usually decreases transit time through the intestines. Choice D is incorrect since fasting generally does not decrease medication excretion.

3. A healthcare provider is providing discharge teaching to a client about self-administering heparin.

• A. Administer medication in the abdomen.
• B. Administer medication in the thigh.
• C. Administer medication in the upper arm.
• D. Administer medication in the buttock.

Correct answer: A

Rationale: Heparin is typically administered in the abdomen for self-injection to avoid muscle tissue and for better absorption. The subcutaneous tissue in the abdomen provides a larger area for injection and is usually recommended for heparin administration. Administering heparin in the thigh, upper arm, or buttock may not be as effective or safe as the abdomen due to variations in absorption rates and potential risks associated with muscle injection.

4. When measuring a client's blood pressure, which approach is the priority for a nurse caring for a client with hypertension?

• A. Obtain the blood pressure under the same conditions each time
• B. Use a different arm for each measurement
• C. Measure the blood pressure while the client is standing
• D. Take multiple readings at different times of the day

Correct answer: A

Rationale: The correct approach when measuring a client's blood pressure, especially for a client with hypertension, is to obtain the blood pressure under the same conditions each time. Consistency in measurement conditions helps ensure accurate and comparable blood pressure readings. Using a different arm for each measurement (Choice B) is not ideal as it can lead to variations in readings. Measuring the blood pressure while the client is standing (Choice C) is not the standard practice and may not provide accurate results. Taking multiple readings at different times of the day (Choice D) may be useful for monitoring blood pressure trends but is not the priority when ensuring accurate individual readings.

5. A nurse is caring for a group of clients. How should the nurse prevent the spread of infection?

• A. Place a client with TB in a negative pressure room.
• B. Use standard precautions only.
• C. Place a client with TB in a private room.
• D. Use barrier precautions only.

Correct answer: A

Rationale: The correct answer is to place a client with TB in a negative pressure room. Tuberculosis (TB) is an airborne infectious disease, and placing the client in a negative pressure room helps prevent the spread of the infection by containing and filtering the air within the room. Standard precautions (Choice B) are important for preventing the spread of infection in general, but specific precautions are needed for airborne diseases like TB. Placing the client in a private room (Choice C) may not provide adequate ventilation and containment of airborne pathogens. Using barrier precautions (Choice D) alone is not sufficient for preventing the airborne transmission of TB.
