1. A nurse evaluates the following arterial blood gas values in a client: pH 7.48, PaO2 98 mm Hg, PaCO2 28 mm Hg, and HCO3 22 mEq/L. Which client condition should the nurse correlate with these results?

A. Diarrhea and vomiting for 36 hours
B. . Anxiety-induced hyperventilation
C. Chronic obstructive pulmonary disease (COPD)
D. Diabetic ketoacidosis and emphysema

Correct answer: B

Rationale:

2. A nurse is assessing a client who has acute pancreatitis and is at risk for an acid-base imbalance. For which manifestation of this acid-base imbalance should the nurse assess?

A. Agitation
B. Kussmaul respirations
C. Seizures
D. Positive Chvosteks sign

Correct answer: B

Rationale:

3. What is the main force that pushes fluid in blood capillaries?

A. Blood pressure.
B. Sodium in the blood plasma.
C. Sodium in the interstitial fluid.
D. Protein in the blood plasma.

Correct answer: A

Rationale: The correct answer is A, blood pressure. Blood pressure is the primary force that pushes fluid out of the capillaries into the surrounding tissues. This pressure difference is essential for the exchange of nutrients, gases, and waste products between the blood and tissues. Choices B, C, and D are incorrect as they do not represent the primary force responsible for pushing fluid in blood capillaries.

4. . You are caring for a patient who has a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Your patients plan of care includes assessment of specific gravity every 4 hours. The results of this test will allow the nurse to as

A. Nutritional status
B. Potassium balance
C. Calcium balance
D. Fluid volume status

Correct answer: D

Rationale:

5. Where is the largest volume of water in the body located?

A. Plasma
B. The fluid inside the cells
C. Interstitial fluid
D. Lymph

Correct answer: B

Rationale: The correct answer is B. The largest volume of water in the body is found inside the cells, known as intracellular fluid. This fluid makes up the majority of the body's total water content. Choices A, C, and D are incorrect because while plasma, interstitial fluid, and lymph are important components of the body's fluid compartments, they do not contain the largest volume of water in the body.
