ATI Fluid Electrolyte and Acid-Base Regulation
1. You are the surgical nurse caring for a 65-year-old female patient who is postoperative day 1 following a thyroidectomy. During your shift assessment, the patient complains of tingling in her lips and fingers. She tells you that she has an intermittent spasm in her wrist and hand and she exhibits increased muscle tone. What electrolyte imbalance should you first suspect?
- A. Hypophosphatemia
- B. Hypocalcemia
- C. Hypermagnesemia
- D. Hyperkalemia
Correct answer: B
Rationale:
2. The chief mechanism for maintaining fluid balance is to:
- A. adjust fluid intake so it equals fluid output.
- B. adjust fluid intake so it is slightly above fluid output.
- C. adjust fluid output so it equals fluid input.
- D. adjust fluid intake so it is slightly below fluid output.
Correct answer: C
Rationale: The correct answer is C: 'adjust fluid output so it equals fluid input.' Maintaining fluid balance involves ensuring that the amount of fluid lost through processes like urination, sweating, and respiration equals the amount of fluid taken in. This ensures that the body stays properly hydrated. Choices A, B, and D are incorrect because they do not focus on the balance between fluid input and output, which is crucial for maintaining proper fluid balance. By adjusting fluid output to equal fluid input, the body can regulate hydration levels effectively, preventing dehydration or overhydration.
3. 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:
4. Which hormone is made in the pituitary gland and increases water absorption in the kidney?
- A. Intracellular fluid
- B. Interstitial fluid
- C. Plasma
- D. ADH
Correct answer: D
Rationale: The correct answer is D, ADH (Antidiuretic hormone). ADH is produced by the pituitary gland and functions to increase water reabsorption in the kidneys. Choices A, B, and C are incorrect as they do not refer to a hormone responsible for increasing water absorption in the kidney.
5. A nurse teaches a client who is prescribed a central vascular access device. Which statement should the nurse include in this clients teaching?
- A. You will need to wear a sling on your arm while the device is in place
- B. There is no risk of infection because sterile technique will be used during insertion.
- C. . Ask all providers to vigorously clean the connections prior to accessing the device.
- D. You will not be able to take a bath with this vascular access device.
