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

A nurse assesses a client who is prescribed a medication that inhibits aldosterone secretion and release. For which potential complications should the nurse assess? (Select all that apply.)

Correct Answer: A

Rationale: Step-by-step rationale for why option A is correct: 1. Inhibition of aldosterone secretion leads to decreased sodium reabsorption and increased water excretion. 2. Decreased aldosterone can result in decreased blood volume and BP, leading to decreased urine output. 3. Monitoring urine output is crucial to assess renal function and fluid balance. 4. A urine output of 25 mL/hr is considered inadequate and can indicate renal impairment or dehydration. Summary: Option A is correct as it directly relates to the mechanism of action of inhibiting aldosterone secretion. Options B, C, and D are incorrect as they do not align with the expected complications of aldosterone inhibition.

Question 3 of 5

A client at risk for mild hypernatremia is being taught by a nurse. Which statement should the nurse include in this client's teaching?

Correct Answer: C

Rationale: The correct answer is C. Reading food labels to determine sodium content is important in managing mild hypernatremia. This allows the client to monitor and control their sodium intake, which can help prevent further elevation of sodium levels. Weighing oneself or checking the pulse does not directly address sodium intake. Choosing cooking methods like baking or grilling is more about reducing fat intake, not sodium.

Question 4 of 5

A gerontologic nurse is teaching students about the high incidence and prevalence of dehydration in older adults. What factors contribute to this phenomenon? Select all that do not apply.

Correct Answer: D

Rationale: The correct answer is D: Increased conservation of sodium. Older adults tend to have an increased conservation of sodium, leading to fluid retention and decreased fluid intake, which can contribute to dehydration. A: Decreased kidney mass is incorrect because it is a factor that can contribute to decreased kidney function but not directly linked to dehydration. B: Decreased renal blood flow can impact kidney function but is not a direct cause of dehydration in older adults. C: Decreased excretion of potassium is not a factor that directly contributes to dehydration in older adults.

Question 5 of 5

A nurse teaches a client who is being discharged home with a peripherally inserted central catheter (PICC). Which statement should the nurse include in this clients teaching?

Correct Answer: A

Rationale: The correct answer is A: "Avoid carrying your grandchild with the arm that has the central catheter." This is important because carrying a child can put strain on the arm where the catheter is inserted, increasing the risk of dislodging or damaging the catheter. It is crucial to protect the integrity of the catheter site to prevent complications such as infection or bleeding. Choice B is incorrect because placing the arm with the central catheter in a sling during the day is unnecessary and could restrict the client's mobility and lead to discomfort. Choice C is incorrect because flushing the PICC line with normal saline should be done by a healthcare professional and not the client themselves. Choice D is incorrect because using the arm with the central catheter for most activities of daily living can increase the risk of accidental dislodgment or damage to the catheter. It is important to be cautious and limit certain activities to protect the catheter and maintain its function.
