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. What would be the most appropriate follow-up by the home care nurse for a 57-year-old male client with a hemoglobin of 10 g/dl and a hematocrit of 32%?

• A. Ask the client if he has noticed any bleeding or dark stools
• B. Tell the client to call 911 and go to the emergency department immediately
• C. Schedule a repeat Hemoglobin and Hematocrit in 1 month
• D. Tell the client to schedule an appointment with a hematologist

Correct answer: A

Rationale: The correct answer is to ask the client if he has noticed any bleeding or dark stools. Normal hemoglobin for males is 13.0 - 18 g/dl, and normal hematocrit for males is 42 - 52%. The values of hemoglobin and hematocrit provided for the client are below normal, indicating mild anemia. The first step for the nurse is to inquire about any signs of bleeding or changes in stools that could suggest bleeding from the gastrointestinal tract. This helps in assessing the possible cause of the low hemoglobin and hematocrit levels. The other options are not appropriate as calling 911 and going to the emergency department immediately is not warranted for mild anemia, scheduling a repeat test in 1 month delays addressing the current concern, and referring the client to a hematologist may be premature without investigating the cause of the low levels first.

3. A client with asthma has low-pitched wheezes present in the final half of exhalation. One hour later, the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client:

• A. Has increased airway obstruction.
• B. Has improved airway obstruction.
• C. Needs to be suctioned.
• D. Exhibits hyperventilation.

Correct answer: B

Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.

4. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

5. The healthcare professional calculates the IV flow rate for a patient receiving an antibiotic. The patient is to receive 100mL of the antibiotic over 30 minutes. The IV infusion set has a drop factor of 10 drops per milliliter. How many drops per minute should the healthcare professional set the IV to deliver?

• A. 11
• B. 19
• C. 26
• D. 33

Correct answer: D

Rationale: To determine the drops per minute for the IV flow rate, you can use the formula: Drops Per Minute = (Milliliters to be infused x Drop Factor) / Time in Minutes. Substituting the given values, you get 100 mL x 10 drops/mL / 30 minutes = 33 drops per minute. Therefore, the correct answer is 33, as the healthcare professional should set the IV to deliver 33 drops per minute to infuse the antibiotic correctly. Choices A, B, and C are incorrect as they do not match the calculated drops per minute based on the provided values.
