ATI Fluid Electrolyte and Acid-Base Regulation Questions

Question 1 of 5

A nurse is caring for clients with electrolyte imbalances on a medical-surgical unit. Which clinical manifestations are correctly paired with the contributing electrolyte imbalance? (Select all that do not apply.)

Correct Answer: B

Rationale: The correct answer is B because hyperphosphatemia can lead to paresthesia with sensations of tingling and numbness due to its effect on nerve function. A, hypokalemia causes muscle weakness but not flaccid paralysis with respiratory depression. C, hyponatremia typically presents with symptoms such as confusion and seizures, not decreased level of consciousness.

Question 2 of 5

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 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 nurse is planning care for a client who is hyperventilating. The clients arterial blood gas values are pH 7.30, PaO2 94 mm Hg, PaCO2 31 mm Hg, and HCO3 26 mEq/L. Which question should the nurse ask when developing this clients plan of care?

Correct Answer: B

Rationale: The correct answer is B: "You appear anxious. What is causing your distress?" because hyperventilation can be triggered by emotional distress or anxiety. By addressing the underlying cause of the hyperventilation, the nurse can provide appropriate interventions to help the client manage their anxiety and subsequently reduce the hyperventilation episodes. A: "Do you take any over-the-counter medications?" - This question is not directly related to addressing the client's anxiety or distress, which is the primary concern in hyperventilation. C: "Do you have a history of anxiety attacks?" - While relevant to understanding the client's medical history, this question does not address the immediate cause of hyperventilation in this specific situation. D: "You are breathing fast. Is this causing you to feel light-headed?" - This question focuses on the physical symptoms of hyperventilation rather than exploring the emotional or psychological triggers, which are essential in managing hyperventilation caused by anxiety.

Question 5 of 5

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.
