ATI Fluid Electrolyte and Acid-Base Regulation Questions

Question 1 of 5

The community health nurse is performing a home visit to an 84-year-old woman recovering from hip surgery. The nurse notes that the woman seems uncharacteristically confused and has dry mucous membranes. When asked about her fluid intake, the patient states, I stop drinking water early in the day because it is just too difficult to get up during the night to go to the bathroom. What would be the nurses best response?

Correct Answer: B

Rationale: The correct answer is B because limiting fluids can lead to dehydration, which can cause confusion and dry mucous membranes. Adjusting the timing of fluids can help maintain hydration without causing frequent nighttime bathroom trips. Choice A is incorrect because hospital readmission is not necessary at this point. Choice C is incorrect as it normalizes confusion post-surgery and dangerous practice of avoiding urination at night. Choice D is incorrect because urine accumulation in the bladder does not directly cause confusion; dehydration is the primary concern.

Question 2 of 5

After providing discharge teaching, a nurse assesses the clients understanding regarding increased risk for metabolic alkalosis. Which statement indicates the client needs additional teaching?

Correct Answer: C

Rationale: The correct answer is C because taking sodium bicarbonate after every meal can actually increase the risk of metabolic alkalosis due to its alkaline nature. Sodium bicarbonate can lead to an excessive build-up of bicarbonate in the bloodstream, causing alkalosis. Choice A is not directly related to metabolic alkalosis. Choice B, taking digoxin, is unrelated to metabolic alkalosis as well. Choice D, drinking six glasses of water due to sweating, does not contribute to metabolic alkalosis as it helps maintain hydration and electrolyte balance.

Question 3 of 5

A nurse assesses a client who is prescribed furosemide (Lasix) for hypertension. For which acid-base imbalance should the nurse assess to prevent complications of this therapy?

Correct Answer: D

Rationale: The correct answer is D: Metabolic alkalosis. Furosemide, a loop diuretic, can lead to potassium depletion and metabolic alkalosis due to excessive loss of chloride and hydrogen ions. The nurse should assess for signs of metabolic alkalosis such as confusion, muscle weakness, and dysrhythmias to prevent complications. Respiratory acidosis and alkalosis are not directly related to furosemide therapy. Metabolic acidosis is less likely due to furosemide's mechanism of action.

Question 4 of 5

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?

Correct Answer: C

Rationale: The correct answer is C: Clip the hair in the area. Clipping the hair is the most appropriate option as it reduces the risk of infection during IV insertion by minimizing the presence of bacteria that may be trapped in the hair. Shaving (B) can cause micro-abrasions leading to increased infection risk. Leaving the hair intact (A) can also trap bacteria. Using a depilatory (D) can cause skin irritation and should be avoided. In summary, clipping the hair is the best option to maintain a clean and safe environment for IV insertion.

Question 5 of 5

. A nurse assesses a client who had an intraosseous catheter placed in the left leg. Which assessment finding is of greatest concern?

Correct Answer: D

Rationale: The correct answer is D. A cool lower extremity can indicate impaired circulation due to the intraosseous catheter placement, leading to compartment syndrome or tissue necrosis. This finding requires immediate intervention to prevent serious complications. Choices A, B, and C are incorrect because the duration of catheter placement, poor vascular access, and the specific location of the catheter do not directly impact circulation and tissue perfusion as significantly as a cool lower extremity.
