Nursing Elites

1. The health care provider writes an order for bacteriologic testing for a patient who has a positive tuberculosis skin test. Which action should the nurse take?

• A. Teach about the reason for the blood tests.
• B. Schedule an appointment for a chest x-ray.
• C. Teach about the need to get sputum specimens for 2 to 3 consecutive days.
• D. Instruct the patient to expectorate three specimens as soon as possible.

Correct answer: C

Rationale: The correct action for the nurse to take is to teach the patient about the need to collect sputum specimens for 2 to 3 consecutive days for bacteriologic testing for M. tuberculosis. It is important to obtain these specimens on different days rather than all at once. Blood tests are not used for tuberculosis testing, so teaching about blood tests is not relevant. While a chest x-ray is important in tuberculosis diagnosis, it is not a bacteriologic test. The appearance on a chest x-ray alone is not sufficient to diagnose TB as other diseases can have similar findings.

2. A client has just been diagnosed with active tuberculosis. Which of the following nursing interventions should the nurse perform to prevent transmission to others?

• A. Begin drug therapy within 72 hours of diagnosis
• B. Place the client in a positive-pressure room
• C. Initiate standard precautions
• D. Place the client in a negative-pressure room

Correct answer: D

Rationale: A client diagnosed with active tuberculosis should be placed in isolation in a negative-pressure room to prevent transmission of infection to others. Placing the client in a negative-pressure room ensures that air is exhausted to the outside and received from surrounding areas, preventing tuberculin particles from traveling through the ventilation system and infecting others. Initiating standard precautions, as mentioned in choice C, is essential for infection control but is not specific to preventing transmission in the case of tuberculosis. Beginning drug therapy within 72 hours of diagnosis, as in choice A, is crucial for the treatment of tuberculosis but does not directly address preventing transmission. Placing the client in a positive-pressure room, as in choice B, is incorrect as positive-pressure rooms are used for clients with compromised immune systems to prevent outside pathogens from entering the room, which is not suitable for a client with active tuberculosis.

3. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?

• A. Administer 30 Units of Lantus Daily
• B. CT of the spine with contrast
• C. X-ray of the abdomen and chest
• D. Administer heparin subcutaneously 5,000 Units every 12 hours

Correct answer: B

Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.

4. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

5. Rhogam is most often used to treat____ mothers that have a ____ infant.

• A. RH positive, RH positive
• B. RH positive, RH negative
• C. RH negative, RH positive
• D. RH negative, RH negative

Correct answer: C

Rationale: Rhogam is administered to RH-negative mothers who have an RH-positive infant to prevent the development of anti-RH antibodies in the mother's system. Choice A (RH positive, RH positive) is incorrect because Rhogam is not used when both mother and infant are RH positive. Choice B (RH positive, RH negative) is incorrect because Rhogam is used when the mother is RH negative, not RH positive. Choice D (RH negative, RH negative) is incorrect as Rhogam is not typically needed if both mother and infant are RH negative.
