ATI Fluid Electrolyte and Acid-Base Regulation Questions
Question 1 of 9
A client at risk for developing hyperkalemia states, 'I love fruit and usually eat it every day, but now I can't because of my high potassium level.' How should the nurse respond?
Correct Answer: C
Rationale: Rationale: Option C is correct because berries, cherries, apples, and peaches are indeed low in potassium compared to other fruits. This response acknowledges the client's love for fruits while providing suitable alternatives to manage potassium levels. By choosing these low-potassium fruits, the client can continue enjoying fruits without exacerbating hyperkalemia. Incorrect options: A: Potatoes and avocados are high in potassium, so they are not suitable substitutes. B: Cooking fruit does not significantly reduce its potassium content. D: This option lacks guidance and does not offer a solution to the client's concern about high potassium levels.
Question 2 of 9
. A nurse is planning care for a nephrology patient with a new nursing graduate. The nurse states, A patient in renal failure partially loses the ability to regulate changes in pH. What is the cause of this partial inability?
Correct Answer: C
Rationale: Rationale: C is correct because in renal failure, the kidneys lose the ability to regenerate and reabsorb bicarbonate, which is essential for maintaining a stable pH level in the body. B is incorrect because the kidneys primarily regulate pH by controlling bicarbonate levels, not through electrolyte changes. A is incorrect because the kidneys do not regulate carbonic acid in the same way. D is incorrect as it does not accurately describe the process of pH regulation in the kidneys.
Question 3 of 9
The nurse caring for a patient post colon resection is assessing the patient on the second postoperative day. The nasogastric tube (NG) remains patent and continues at low intermittent wall suction. The IV is patent and infusing at 125 mL/hr. The patient reports pain at the incision site rated at a 3 on a 0-to-10 rating scale. During your initial shift assessment, the patient complains of cramps in her legs and a tingling sensation in her feet. Your assessment indicates decreased deep tendon reflexes (DTRs) and you suspect the patient has hypokalemia. What other sign or symptom would you expect this patient to exhibit
Correct Answer: B
Rationale: The correct answer is B: Dilute urine. Hypokalemia can lead to kidney dysfunction, causing the kidneys to excrete more water along with electrolytes, resulting in dilute urine. This is a manifestation of the body's attempt to compensate for low potassium levels by excreting excess water. The other choices are incorrect because: A) Diarrhea is more commonly associated with hyperkalemia, not hypokalemia. C) Increased muscle tone is not a typical sign of hypokalemia; rather, hypokalemia can lead to muscle weakness or paralysis due to impaired muscle function. D) Joint pain is not a typical symptom of hypokalemia; joint pain is more commonly associated with other conditions such as arthritis or inflammation.
Question 4 of 9
A client at risk for developing hyperkalemia states, 'I love fruit and usually eat it every day, but now I can't because of my high potassium level.' How should the nurse respond?
Correct Answer: C
Rationale: Rationale: Option C is correct because berries, cherries, apples, and peaches are indeed low in potassium compared to other fruits. This response acknowledges the client's love for fruits while providing suitable alternatives to manage potassium levels. By choosing these low-potassium fruits, the client can continue enjoying fruits without exacerbating hyperkalemia. Incorrect options: A: Potatoes and avocados are high in potassium, so they are not suitable substitutes. B: Cooking fruit does not significantly reduce its potassium content. D: This option lacks guidance and does not offer a solution to the client's concern about high potassium levels.
Question 5 of 9
A medical-surgical nurse is concerned about the incidence of complications related to IV therapy, including bloodstream infection. Which intervention should the nurse suggest to the management team to make the biggest impact on decreasing complications
Correct Answer: A
Rationale: The correct answer is A: Initiate a dedicated team to insert access devices. This intervention is the most effective in decreasing complications related to IV therapy because having a dedicated team specialized in inserting access devices ensures that the procedure is done correctly each time, reducing the risk of complications such as bloodstream infections. Choice B is not as effective because additional education for all nurses may not guarantee consistent skill levels in IV insertion. Choice C may limit access but does not address the root cause of complications. Choice D focuses on skin preparation, which is important but not as impactful as having a specialized team for IV insertion.
Question 6 of 9
A nurse is caring for a client who has just experienced a 90-second tonic-clonic seizure. The clients arterial blood gas values are pH 6.88, PaO2 50 mm Hg, PaCO2 60 mm Hg, and HCO3 22 mEq/L. Which action should the nurse take first?
Correct Answer: A
Rationale: The correct answer is A: Apply oxygen by mask or nasal cannula. The client is experiencing respiratory acidosis due to inadequate ventilation and oxygenation during the seizure. Providing oxygen will help improve oxygenation and correct the respiratory acidosis. This is the priority to address the immediate physiological need. Choice B is incorrect as applying a paper bag can lead to rebreathing of carbon dioxide, worsening the respiratory acidosis. Choice C is incorrect as sodium bicarbonate is not indicated in this situation and can potentially worsen the acid-base imbalance. Choice D is incorrect as administering glucose and insulin is not relevant to correcting the respiratory acidosis.
Question 7 of 9
A nurse is assessing a client who has an electrolyte imbalance related to renal failure. For which potential complications of this electrolyte imbalance should the nurse assess? (Select all that do mot apply.)
Correct Answer: B
Rationale: Correct Answer: B - Slow, shallow respirations Rationale: 1. Electrolyte imbalance in renal failure often leads to respiratory alkalosis, causing rapid and deep respirations, not slow and shallow. 2. Electrocardiogram changes (A) are common with electrolyte imbalances, particularly potassium and calcium. 3. Paralytic ileus (C) is a complication of electrolyte imbalances, affecting gastrointestinal motility. 4. Skeletal muscle weakness (D) is a common manifestation of electrolyte imbalances, especially potassium and magnesium deficiencies. Summary: Choice B is incorrect because slow, shallow respirations are not typically associated with electrolyte imbalances related to renal failure. Choices A, C, and D are commonly seen complications of electrolyte imbalances and should be assessed by the nurse.
Question 8 of 9
A home care nurse prepares to administer intravenous medication to a client. The nurse assesses the site and reviews the clients chart prior to administering the medication: Client: Thomas Jackson DOB: 5/3/1936 Gender: Male January 23 (Today): Right uppe
Correct Answer: B
Rationale: The correct answer is B: Administer the prescribed medication. The nurse has assessed the client's site and reviewed the chart, indicating readiness to administer the medication. It is crucial to follow the healthcare provider's order and administer the prescribed medication as planned. Notifying the provider (A) is unnecessary if all assessments are normal. Discontinuing the PICC line (C) without a valid reason can lead to complications. Switching to oral route (D) should only be considered if there are specific contraindications for the intravenous route. It's important to prioritize safe and effective medication administration based on the client's condition and healthcare provider's orders.
Question 9 of 9
You are caring for a patient with a secondary diagnosis of hypermagnesemia. What assessment finding would be most consistent with this diagnosis?
Correct Answer: D
Rationale: The correct answer is D: Shallow respirations. Hypermagnesemia can lead to respiratory depression due to its inhibitory effect on the central nervous system. Shallow respirations are a common respiratory manifestation of hypermagnesemia. Hypertension (choice A) is not typically associated with hypermagnesemia. Kussmaul respirations (choice B) are deep, rapid breathing patterns seen in metabolic acidosis, not hypermagnesemia. Increased deep tendon reflexes (DTRs) (choice C) are more indicative of hypomagnesemia, as magnesium deficiency can lead to hyperexcitability of nerves and muscles, resulting in increased DTRs.
