ATI Fluid Electrolyte and Acid-Base Regulation

1. . A 73-year-old man comes into the emergency department (ED) by ambulance after slipping on a small carpet in his home. The patient fell on his hip with a resultant fracture. He is alert and oriented; his pupils are equal and reactive to light and accommodation. His heart rate is elevated, he is anxious and thirsty, a Foley catheter is placed, and 40 mL of urine is present. What is the nurses most likely explanation for the low urine output?

A. The man urinated prior to his arrival to the ED and will probably not need to have the Foley catheter kept in place.
B. The man likely has a traumatic brain injury, lacks antidiuretic hormone (ADH), and needs vasopressin.
C. The man is experiencing symptoms of heart failure and is releasing atrial natriuretic peptide that results in decreased urine output.
D. The man is having a sympathetic reaction, which has stimulated the reninangiotensinaldosterone system that results in diminished urine output.

Correct answer: D

Rationale:

2. 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.

3. A patient's lab results show a slight decrease in potassium. The physician has declined to treat with drug therapy but has suggested increasing the potassium through diet. Which of the following would be a good source of potassium?

A. Apples
B. Asparagus
C. Carrots
D. Bananas

Correct answer: D

Rationale: Bananas are an excellent source of potassium, making them a good choice to increase potassium levels through diet. While apples, asparagus, and carrots are nutritious, they are not particularly high in potassium compared to bananas. Therefore, choosing bananas would be more effective in increasing the patient's potassium intake.

4. When considering overhydration:

A. occurs less often than dehydration.
B. can strain the kidneys.
C. can be caused by giving intravenous fluids too rapidly.
D. less common than dehydration.

Correct answer: C

Rationale: The correct answer is C. Overhydration can occur when intravenous fluids are administered too quickly, overwhelming the body's ability to excrete the excess fluid. Choices A, B, and D are incorrect. Choice A is incorrect because overhydration is less common than dehydration. Choice B is incorrect because while overhydration can strain the kidneys, it is not due to the burden being too heavy. Choice D is incorrect because dehydration is more common than overhydration.
