1. A nurse is planning care for a client who is hyperventilating. The clients arterial blood gas values are pH 7.30, PaO2 94 mm Hg, PaCO2 31 mm Hg, and HCO3 26 mEq/L. Which question should the nurse ask when developing this clients plan of care?

A. Do you take any over-the-counter medications?
B. You appear anxious. What is causing your distress?
C. Do you have a history of anxiety attacks?
D. You are breathing fast. Is this causing you to feel light-headed?

Correct answer: B

Rationale:

2. You are caring for a patient admitted with a diagnosis of acute kidney injury. When you review your patients most recent laboratory reports, you note that the patients magnesium levels are high. You should prioritize assessment for which of the followin

A. Diminished deep tendon reflexes
B. Tachycardia
C. Cool, clammy skin
D. Acute flank pain

Correct answer: A

Rationale:

3. What is the fluid that surrounds the cells called?

A. plasma
B. interstitial fluid
C. intracellular fluid
D. edema

Correct answer: B

Rationale: The correct answer is interstitial fluid. Interstitial fluid is the fluid that surrounds and fills the spaces between cells, facilitating nutrient and waste exchange. Plasma, referred to in choice A, is the liquid part of blood. Choice C, intracellular fluid, is the fluid inside cells. Choice D, edema, is an abnormal accumulation of fluid in interstitial spaces, causing swelling.

4. The baroreceptors, located in the left atrium and in the carotid and aortic arches, respond to changes in the circulating blood volume and regulate sympathetic and parasympathetic neural activity as well as endocrine activities. Sympathetic stimulation constricts renal arterioles, causing what effect?

A. Decrease in the release of aldosterone
B. Increase of filtration in the Loop of Henle
C. Decrease in the reabsorption of sodium
D. Decrease in glomerular filtration

Correct answer: D

Rationale:

5. The healthcare professional working in the PACU is aware that which of the following procedures may contribute to extracellular losses?

A. Removal of an ingrown toenail
B. Tooth extraction
C. Abdominal surgery
D. Cataract surgery

Correct answer: C

Rationale: Fluid loss from the extracellular compartment can be caused by abdominal surgery as it involves opening the abdominal cavity, potentially leading to significant fluid losses. Choices A, B, and D do not typically result in substantial extracellular losses compared to abdominal surgery.
