Extract:
Question 1 of 5
The nurse is to start oxygen therapy via nasal cannula. Which action is correct?
Correct Answer: D
Rationale: Inserting the cannula 1 cm into the nostrils ensures proper oxygen delivery. High flow rates, petrolatum, or mask pre-oxygenation are incorrect.
Question 2 of 5
The nurse is caring for a client with a history of heart failure who is receiving torsemide (Demadex) 20 mg PO daily. Which of the following laboratory results should the nurse report immediately?
Correct Answer: A
Rationale: Hypokalemia (3.0 mEq/L) is a serious torsemide side effect, risking arrhythmias in heart failure. Options B, C, and D are normal.
Question 3 of 5
The nurse is caring for a neonate with an infection. The nurse would be MOST concerned if which of the following was observed?
Correct Answer: D
Rationale: A respiratory rate of 65 at rest (normal 30–50) indicates tachypnea, suggesting sepsis or hypoxia. Options A, B, and C are less concerning.
Question 4 of 5
The nurse is to insert an indwelling catheter in a male. Which action is appropriate?
Correct Answer: B
Rationale: Washing hands before catheter insertion is critical to maintain a sterile field and prevent infection. Cleansing the meatus occurs after hand washing, a 45-degree angle is incorrect (90 degrees is typical), and the balloon is inflated post-insertion.
Question 5 of 5
The nurse is caring for a client with a history of bipolar disorder.
Correct Answer: C
Rationale: Stating that the medication can be stopped when feeling better indicates a misunderstanding, as lithium requires consistent use to maintain therapeutic levels and prevent mood swings. Hydration, blood monitoring, and sodium awareness are correct.
