Question 1 of 5
A nurse is caring for a client receiving oxygen therapy via a Venturi mask. What is an important nursing intervention for this client?
Correct Answer: B
Rationale: Adjusting the oxygen flow rate as prescribed (B) is essential for a Venturi mask, ensuring the exact FiO2 (24-50%) matches the order for precise delivery. Continuous SpO2 (A) may be excessive. Lung sounds q-shift (C) are routine. Loose fit (D) reduces accuracy. Prescription adherence, per respiratory standards, optimizes therapy.
Question 2 of 5
Which of the following conditions is most likely related to the development of renal calculi?
Correct Answer: A
Rationale: Gout increases renal calculi risk due to elevated uric acid levels forming stones, a metabolic link well-documented in nephrology unlike pancreatitis (calcium stones rarely), fractures, or disc disease, which lack direct renal impact. Nurses connect this condition to stone formation for prevention teaching, like hydration and dietary purine reduction, addressing a client's predisposition to this painful urologic issue.

Question 5 of 5
A client is being discharged home following a heart catheterization. Which instruction should be included in the discharge teaching?
