Question 1 of 5
A nurse received a client who has had multiple episodes of pneumonia in the past year. What intervention is a PRIORITY for this client before starting treatment?
Correct Answer: A
Rationale: Sputum culture and sensitivity testing is crucial in identifying the causative organism of pneumonia. It helps determine the most effective antibiotic treatment.
Question 2 of 5
A home health nurse is assessing an older adult client in the home who has decreased vision due to a history of glaucoma. Which of the following findings should the nurse identify as a safety risk?
Correct Answer: D
Rationale: Scatter rugs pose a major fall risk, especially for visually impaired clients. Removing or securing them enhances safety and reduces accident risk.
Question 3 of 5
A nurse is caring for a client with an elevated serum potassium level of 6.0 mEq/L (3.5-5.0 mEq/L). Which scheduled medication should the nurse plan to administer?
Correct Answer: D
Rationale: Sodium polystyrene sulfonate is a cation-exchange resin that is specifically used to treat hyperkalemia. It works by binding to potassium in the gastrointestinal tract, which is then excreted through the feces. This process effectively lowers serum potassium levels. Given its mechanism of action and its specific indication for treating hyperkalemia, sodium polystyrene sulfonate is the appropriate choice for a patient with an elevated potassium level of 6.0 mEq/L.
Question 4 of 5
A nurse is caring for a client who is postoperative following abdominal surgery. The nurse discovers a loop of bowel protruding through an opening in the surgical incision. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: Applying moistened sterile gauze to the site is the correct action. This keeps the exposed bowel moist and protected until surgical intervention can be performed.
Question 5 of 5
A registered nurse interprets that a scribbled medication order reads 25 mg. The nurse administers 25 mg of the medication to a patient and then discovers that the dose was incorrectly interpreted and should have been 15 mg. Who is ultimately responsible for the error?
Correct Answer: A
Rationale: The nurse is ultimately responsible for the error. Nurses are accountable for verifying medication orders and ensuring accurate administration. Misinterpreting a scribbled order indicates a failure to clarify the prescription, which is within the nurse's responsibility.
