Question 1 of 5
The nurse must know that the most accurate oxygen delivery system available is
Correct Answer: A
Rationale: The most accurate way to deliver oxygen to the client is through a Venturi system such as the Venti Mask. The Venti Mask is a high flow device that entrains room air into a reservoir device on the mask and mixes the room air with 100% oxygen. The size of the opening to the reservoir determines the concentration of oxygen. The client's respiratory rate and respiratory pattern do not affect the concentration of oxygen delivered. The maximum amount of oxygen that can be delivered by this system is 53%.
Question 2 of 5
The nurse should visit which of the following clients first?
Correct Answer: C
Rationale: Chest pain in a client with a history of angina suggests possible acute coronary syndrome, requiring immediate assessment to rule out myocardial infarction.
Question 3 of 5
A 70 year-old woman is evaluated in the emergency department for a wrist fracture of unknown causes. During the process of taking client history, which of these items should the nurse identify as related to the client's greatest risk factors for osteoporosis?
Correct Answer: B
Rationale: Taking high doses of steroids for arthritis for many years. The use of steroids, especially at high doses over time, increases the risk for osteoporosis. The other options also predispose to osteoporosis, as do low bone mass, poor calcium absorption and moderate to high alcohol ingestion. Long-term steroid treatment is the most significant risk factor, however.

Correct Answer: D
Rationale: Hydrochlorothiazide causes potassium loss; eating potassium-rich apricots indicates understanding. Options A, B, and C are incorrect.

Question 5 of 5
Which of the following nursing actions is BEST?
Correct Answer: C
Rationale: Strategy: All answers are implementations. Determine the outcome of each answer choice. Is it desired? (1) Aldactone is potassium-sparing diuretic and is an oral medication, patient is NPO for procedure (2) is not feasible prior to the cardiac cath because the client is NPO (3) correct-signs and symptoms are indicative of hypokalemia; stat serum K⺠level is needed to confirm the K⺠level prior to going for cardiac catheterization (4) is unnecessary at this time
