ATI Fluid Electrolyte and Acid-Base Regulation
1. A nurse educator is reviewing peripheral IV insertion with a group of novice nurses. How should these nurses be encouraged to deal with excess hair at the intended site?
- A. Leave the hair intact
- B. Shave the area.
- C. Clip the hair in the area.
- D. Remove the hair with a depilatory.
Correct answer: C
Rationale:
2. A nurse is assessing clients on a medical-surgical unit. Which clients are at increased risk for hypophosphatemia? (Select all that do not apply.)
- A. A 36-year-old who is malnourished
- B. A 42-year-old with uncontrolled diabetes
- C. A 76-year-old who is prescribed antacids
- D. 50-year-old with hyperparathyroidism
Correct answer: C
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. A female patient is discharged from the hospital after having an episode of heart failure. She's prescribed daily oral doses of digoxin (Lanoxin) and furosemide (Lasix). Two days later, she tells her community health nurse that she feels weak and her heart 'flutters' frequently. What action should the nurse take?
- A. Tell the patient to rest more frequently.
- B. Advise the patient to discontinue digoxin and contact the physician.
- C. Contact the physician, report the symptoms, and request a blood sample to determine the patient's potassium level.
- D. Instruct the patient to avoid caffeine-containing foods.
Correct answer: C
Rationale: The correct action for the nurse to take is to contact the physician, report the patient's symptoms, and request a blood sample to determine the patient's potassium level. Furosemide, a potassium-wasting diuretic, can lead to hypokalemia, causing weakness and palpitations. Therefore, checking the potassium level is crucial in this situation. Simply telling the patient to rest more frequently won't address the underlying issue of potassium depletion. While digoxin can cause adverse effects, in this case, the symptoms are more likely related to furosemide-induced potassium loss. Instructing the patient to avoid caffeine-containing foods may be beneficial in general, but it wouldn't directly address the potassium depletion that needs urgent attention.
5. A patient who is being treated for pneumonia starts complaining of sudden shortness of breath. An arterial blood gas (ABG) is drawn. The ABG has the following values: pH 7.21, PaCO2 64 mm Hg, HCO3 = 24 mm Hg. What does the ABG reflect?
- A. Respiratory acidosis
- B. Metabolic alkalosis
- C. Respiratory alkalosis
- D. Metabolic acidosis
Correct answer: A
