ATI Fluid Electrolyte and Acid-Base Regulation
1. 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:
2. A patient's most recent laboratory results show a slight decrease in potassium. The physician has opted to forego drug therapy but has suggested increasing the patient's dietary intake of potassium. 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. They are a popular choice for increasing dietary potassium intake due to their rich potassium content. Apples, asparagus, and carrots do not contain as high levels of potassium as bananas. While these fruits and vegetables are nutritious, they are not as effective in addressing a potassium deficiency as bananas.
3. A nurse is assessing clients for fluid and electrolyte imbalances. Which client should the nurse assess first for potential hyponatremia?
- A. A 34-year-old on NPO status who is receiving intravenous D5W
- B. A 50-year-old with an infection who is prescribed a sulfonamide antibiotic
- C. A 67-year-old who is experiencing pain and is prescribed ibuprofen (Motrin)
- D. A 73-year-old with tachycardia who is receiving digoxin (Lanoxin)
Correct answer: A
Rationale: The correct answer is the 34-year-old on NPO status receiving intravenous D5W because D5W is a hypotonic solution that can dilute the blood's sodium levels, leading to hyponatremia. Patients on NPO status rely solely on intravenous fluids for hydration, making them more susceptible to electrolyte imbalances. Choices B, C, and D are less likely to cause hyponatremia. Choice B, the 50-year-old with an infection on a sulfonamide antibiotic, is at risk for allergic reactions or renal issues. Choice C, the 67-year-old taking ibuprofen, is at risk for gastrointestinal bleeding or kidney problems. Choice D, the 73-year-old on digoxin with tachycardia, is more likely to experience digoxin toxicity, affecting the heart's rhythm.
4. What can cause dehydration?
- A. Prolonged vomiting.
- B. Prolonged diarrhea.
- C. Too little fluid intake.
- D. Prolonged vomiting, diarrhea, and too little fluid intake.
Correct answer: D
Rationale: Dehydration can result from significant fluid loss due to vomiting, diarrhea, or inadequate fluid intake. Prolonged vomiting and diarrhea lead to excessive fluid loss from the body, contributing to dehydration. Similarly, not consuming enough fluids can also result in dehydration. Choice A and B are too specific as they only mention one cause each, while choice C is also correct but does not encompass all the potential causes of dehydration as mentioned in choice D.
5. The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?
- A. Choose a hairless site if available.
- B. Consider potential effects on the patients mobility when selecting a site.
- C. Have the patient briefly hold his arm over his head before insertion
- D. Leave the tourniquet on for at least 3 minutes.
Correct answer: B
