ATI Fluid Electrolyte and Acid-Base Regulation
1. You are called to your patients room by a family member who voices concern about the patients status. On assessment, you find the patient tachypnic, lethargic, weak, and exhibiting a diminished cognitive ability. You also find 3+ pitting edema. What electrolyte imbalance is the most plausible cause of this patients signs and symptoms?
- A. Hypocalcemia
- B. Hyponatremia
- C. Hyperchloremia
- D. Hypophosphatemia
Correct answer: Hyperchloremia
Rationale:
2. The patient experienced a surgical procedure, and Betadine was utilized as the surgical prep. Two days postoperatively, the nurse's assessment indicates that the incision is red and has a small amount of purulent drainage. The patient reports tenderness at the incision site. The patient's temperature is 100.5°F, and the WBC is 10,500/mm³. Which action should the nurse take first?
- A. Reevaluate the temperature and white blood cell count in 4 hours.
- B. Check which solution was used for skin preparation in surgery.
- C. Plan to change the surgical dressing during the shift.
- D. Utilize SBAR to notify the primary health care provider.
Correct answer: D
Rationale: The patient is showing signs of a possible surgical site infection, including redness, purulent drainage, tenderness, elevated temperature, and increased white blood cell count. These symptoms suggest the need for immediate action to address a potential complication. Utilizing SBAR to notify the primary health care provider is crucial as it allows for effective communication of the patient's condition and the need for further assessment and intervention. Reevaluating the temperature and white blood cell count later, checking the solution used for skin preparation, or planning to change the dressing do not address the urgent need for intervention and communication with the healthcare provider.
3. The surgical mask the perioperative nurse is wearing becomes moist. Which action will the perioperative nurse take next?
- A. Do not change the mask if the nurse is comfortable.
- B. Change the mask when relieved by the next shift.
- C. Apply a new mask.
- D. Reapply the mask after it air-dries.
Correct answer: C
Rationale: When a surgical mask becomes moist, it loses its effectiveness as a barrier against microorganisms. Therefore, the perioperative nurse should apply a new mask. Choice A is incorrect because a moist mask should not be continued to be worn even if the nurse is comfortable. Choice B is not the best course of action as the mask should be changed immediately when it becomes moist. Choice D is also incorrect as waiting for the mask to air-dry is not recommended due to the loss of barrier effectiveness.
4. Are M6 practical nurses utilized in field units with patient holding capabilities?
- A. Yes
- B. No
- C. -
- D. -
Correct answer: A
Rationale: Yes, M6 practical nurses are utilized in field units with patient holding capabilities. These nurses play a crucial role in providing care and support in various healthcare settings. Given this context, the correct answer is 'Yes.' Choice B, 'No,' is incorrect because M6 practical nurses can indeed work in field units with patient holding capabilities, as stated in the extract. Choices C and D are not applicable in this question.
5. When selecting a site on the hand or arm for insertion of an IV catheter, the nurse should:
- A. Choose a proximal site.
- B. Choose a distal site.
- C. Have the patient hold their arm in a dependent position.
- D. Leave the tourniquet on for no longer than 2 minutes.
Correct answer: B
Rationale: When selecting a site for insertion of an IV catheter, the nurse should choose a distal site, not a proximal site. Opting for a distal site ensures that upper veins remain available for future cannulations. Instructing the patient to hold their arm in a dependent position can enhance blood flow, aiding in the procedure. It is crucial never to leave a tourniquet on for more than 2 minutes as prolonged restriction can lead to complications. Choice A is incorrect because a proximal site is not preferred for IV insertion. Choice C is incorrect as having the patient hold their arm over their head is not necessary and may impede proper blood flow. Choice D is incorrect as leaving the tourniquet on for at least 5 minutes is excessive and can be harmful.
