Nursing Elites

1. 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.

2. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

• A. 60 microdrops/minute
• B. 20 microdrops/minute
• C. 30 microdrops/minute
• D. 40 microdrops/minute

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

3. A man is prescribed lithium to treat bipolar disorder. The nurse is most concerned about lithium toxicity when he notices which of these assessment findings?

• A. The patient states he had a manic episode a week ago
• B. The patient states he has been having diarrhea every day
• C. The patient presents as severely depressed
• D. The patient has a rash and pruritus on his arms and legs

Correct answer: B

Rationale: The correct answer is when the patient states he has been having diarrhea every day. Persistent diarrhea can lead to dehydration, which can increase the risk of lithium toxicity. The other options, such as a manic episode, severe depression, or rash and pruritus, are not directly associated with an increased risk of lithium toxicity.

4. Which of the following complaints is characteristic of a patient with Bell's Palsy?

• A. Paralysis of the right or left arm
• B. Malfunction of a certain cranial nerve
• C. A sub-condition of Cerebral Palsy
• D. A side effect of a stroke

Correct answer: B

Rationale: Bell's Palsy is characterized by the dysfunction of the Facial nerve, which is cranial nerve VII. This dysfunction leads to facial muscle weakness or paralysis, not affecting the arms. Choice A is incorrect as Bell's Palsy specifically involves facial muscles, not the arms. Choice C is incorrect as it incorrectly associates Bell's Palsy with a different condition, Cerebral Palsy. Choice D is incorrect as Bell's Palsy is not a side effect of a stroke but rather a distinct condition with its own etiology.

5. A patient with right lower-lobe pneumonia has been treated with IV antibiotics for 3 days. Which assessment data obtained by the nurse indicates that the treatment has been effective?

• A. Bronchial breath sounds are heard at the right base.
• B. The patient coughs up small amounts of green mucus.
• C. The patients white blood cell (WBC) count is 9000/L
• D. Increased tactile fremitus is palpable over the right chest

Correct answer: C

Rationale: The normal WBC count indicates that the antibiotics have been effective. All the other data suggest that a change in treatment is needed.
