Nursing Elites

1. A nurse assesses a client who has a radial artery catheter. Which assessment should the nurse complete first?

• A. . Amount of pressure in fluid container
• B. Date of catheter tubing change
• C. Percent of heparin in infusion container
• D. . Presence of an ulnar pulse

Correct answer: D

Rationale:

2. When does dehydration begin to occur?

• A. the body reduces fluid output to zero.
• B. the body increases the release of ANH.
• C. the salivary secretions decrease.
• D. the salivary secretions increase.

Correct answer: C

Rationale: Dehydration leads to a decrease in the body's fluid levels, causing the salivary glands to produce less saliva, resulting in a dry mouth. Therefore, when dehydration begins to occur, salivary secretions decrease. Choice A is incorrect because the body does not reduce fluid output to zero during dehydration; it tries to conserve fluids. Choice B is incorrect as dehydration does not directly increase the release of ANH (Atrial Natriuretic Hormone). Choice D is incorrect because salivary secretions do not increase but decrease during dehydration.

3. A nurse assesses a client who was started on intraperitoneal therapy 5 days ago. The client reports abdominal pain and feeling warm. For which complication of this therapy should the nurse assess this client?

• A. Allergic reaction
• B. Bowel obstruction
• C. Catheter lumen occlusion
• D. Infection

Correct answer: D

Rationale:

4. Electrolytes:

• A. do not form when glucose is added to water.
• B. dissociate in water solutions, but do not form ions.
• C. form ions in water solutions, but do not necessarily dissociate.
• D. dissociate in water solutions and form ions in water solutions.

Correct answer: D

Rationale: The correct answer is D. Electrolytes are substances that dissociate into ions when dissolved in water, allowing the solution to conduct electricity. Choice A is incorrect because glucose does not form electrolytes when added to water. Choice B is incorrect as it states that electrolytes dissociate but do not form ions, which is inaccurate as electrolytes do form ions in water solutions. Choice C is also incorrect as it states that electrolytes form ions but may not necessarily dissociate, which goes against the definition of electrolytes that must dissociate into ions for conductivity. Therefore, choice D is the most accurate as it correctly describes that electrolytes dissociate in water solutions and form ions, highlighting the essential characteristics of electrolytes.

5. A nurse assesses a client who is admitted with an acid-base imbalance. The clients arterial blood gas values are pH 7.32, PaO2 85 mm Hg, PaCO2 34 mm Hg, and HCO3 16 mEq/L. What action should the nurse take next?

• A. Assess clients rate, rhythm, and depth of respiration.
• B. Measure the clients pulse and blood pressure.
• C. Document the findings and continue to monitor.
• D. Notify the physician as soon as possible.

Correct answer: A
