Correct Answer: A

Rationale: The correct answer is A: Client with pancreatitis who has continuous nasogastric suctioning. Pancreatitis can lead to gastrointestinal losses of potassium, and continuous nasogastric suctioning can further exacerbate this potassium loss, putting the client at risk for hypokalemia. The other choices are incorrect because: B: ACE inhibitors can cause hyperkalemia, not hypokalemia. C: Blood transfusions can lead to hyperkalemia due to the potassium content in blood products. D: Uncontrolled diabetes and a serum pH level of 7.33 are not directly associated with hypokalemia.

Correct Answer: B

Rationale: The correct answer is B. Straining all urine output and assessing for urinary stones is important for a client with hypocalcemia as they are at risk for developing kidney stones due to increased calcium excretion. By straining urine, the nurse can monitor for the presence of stones. A, using a draw sheet to reposition the client, is not directly related to hypocalcemia. C, providing nonslip footwear, is important for fall prevention but not specific to hypocalcemia. D, since it is not provided, cannot be evaluated.

Correct Answer: B

Rationale: The correct answer is B: Anxiety-induced hyperventilation. The arterial blood gas values show a pH of 7.48 (alkalosis) with low PaCO2 (respiratory alkalosis), which is consistent with hyperventilation due to anxiety. HCO3 is within normal range, ruling out metabolic causes. A: Diarrhea and vomiting would lead to metabolic acidosis with low pH and decreased HCO3. C: COPD would typically present with respiratory acidosis (high PaCO2) and normal to high HCO3. D: Diabetic ketoacidosis and emphysema would show metabolic acidosis with low pH and low HCO3.

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.

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.
