1. A nurse is caring for a patient who requires measurement of specific gravity every 4 hours. What does this test detect?

• A. Nutritional deficit
• B. Hyperkalemia
• C. Hypercalcemia
• D. Fluid volume status

Correct answer: D

Rationale: Specific gravity is a test used to determine the concentration of solutes in the urine, reflecting the kidney's ability to concentrate urine. Changes in specific gravity can indicate fluid volume status, such as dehydration (fluid volume deficit) or overhydration (fluid volume excess). Options A, B, and C are incorrect as specific gravity does not directly detect nutritional deficits, hyperkalemia, or hypercalcemia.

2. After administering 40 mEq of potassium chloride, a nurse evaluates the clients response. Which manifestations indicate that treatment is improving the clients hypokalemia? (Select all tha do not t apply.)

• A. Strong productive cough
• B. Active bowel sounds
• C. U waves present on the electrocardiogram (ECG)
• D.

Correct answer: C

Rationale:

3. You are the nurse evaluating a newly admitted patients laboratory results, which include several values that are outside of reference ranges. Which of the following would cause the release of antidiuretic hormone (ADH)?

• A. Increased serum sodium
• B. Decreased serum potassium
• C. Decreased hemoglobin
• D. Increased platelets

Correct answer: A

Rationale:

4. The nurse who assesses the patient's peripheral IV site and notes edema around the insertion site will document which complication related to IV therapy?

• A. Air emboli
• B. Phlebitis
• C. Infiltration
• D. Fluid overload

Correct answer: C

Rationale: Infiltration is the administration of non-vesicant solution or medication into the surrounding tissue. This can occur when the IV cannula dislodges or perforates the vein's wall. Infiltration is characterized by edema around the insertion site, leakage of IV fluid from the insertion site, discomfort, and coolness in the area of infiltration, and a significant decrease in the flow rate. Air emboli (Choice A) involves air entering the bloodstream. Phlebitis (Choice B) is inflammation of a vein. Fluid overload (Choice D) is an excessive volume of fluid in the circulatory system.

5. Which condition can result from prolonged vomiting or diarrhea?

• A. Intracellular fluid
• B. Interstitial fluid
• C. Dehydration
• D. Electrolyte

Correct answer: C

Rationale: The correct answer is C: Dehydration. Prolonged vomiting or diarrhea can lead to significant fluid loss, causing dehydration. Intracellular fluid (choice A) and interstitial fluid (choice B) refer to specific compartments of body fluid and are not conditions resulting from vomiting or diarrhea. Electrolytes (choice D) are minerals that help maintain fluid balance in the body but are not the condition directly resulting from prolonged vomiting or diarrhea.
