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. A child is seen in the emergency department for scarlet fever. Which of the following descriptions of scarlet fever is not correct?

• A. Scarlet fever is caused by infection with group A Streptococcus bacteria.
• B. "Strawberry tongue"? is a characteristic sign.
• C. Petechiae occur on the soft palate.
• D. The pharynx is red and swollen.

Correct answer: C

Rationale: Petechiae on the soft palate are not a typical finding in scarlet fever. Scarlet fever is caused by group A Streptococcus bacteria, often presenting with a strawberry tongue, red and swollen pharynx, and a sandpaper-like rash. The presence of petechiae on the soft palate is more commonly associated with conditions like rubella rather than scarlet fever. Therefore, this description is not correct in the context of scarlet fever.

3. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?

• A. Administer bicarbonate.
• B. Complete a head-to-toe assessment.
• C. Place the patient on high-flow oxygen.
• D. Obtain repeat arterial blood gases (ABGs).

Correct answer: C

Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.

4. A patient's chart indicates a history of hyperkalemia. Which of the following would you not expect to see with this patient if this condition were acute?

• A. Decreased HR
• B. Paresthesias
• C. Muscle weakness of the extremities
• D. Migraines

Correct answer: D

Rationale: The correct answer is 'Migraines.' Migraines are not a symptom typically associated with hyperkalemia. In acute hyperkalemia, one would not expect to see migraines. Symptoms of hyperkalemia often include muscle weakness, paresthesias, and cardiac manifestations such as bradycardia or even cardiac arrest. Therefore, choices A, B, and C are more commonly associated with acute hyperkalemia compared to migraines, making it the correct choice.

5. To prepare a 56-year-old male patient with ascites for paracentesis, the nurse should?

• A. place the patient on NPO status.
• B. assist the patient to lie flat in bed.
• C. ask the patient to empty the bladder.
• D. position the patient on the right side.

Correct answer: C

Rationale: To prepare a patient with ascites for paracentesis, the nurse should ask the patient to empty the bladder. This is important to decrease the risk of bladder perforation during the procedure. The patient should be positioned in Fowler's position to facilitate the procedure, not lie flat in bed, which can compromise breathing. Placing the patient on NPO status is unnecessary as sedation is not typically required for paracentesis. Positioning the patient on the right side is not a standard preparatory measure for paracentesis.
