Question 1 of 5
A postoperative patient who had surgery for a perforated gastric ulcer has been receiving nasogastric suction for 3 days. The patient now has a serum sodium level of 127 mEq/L (127 mmol/L). Which prescribed therapy should the nurse question?
Correct Answer: A
Rationale: The nurse should question the prescription to infuse 5% dextrose in water at 125 mL/hr because the patient's gastric suction has been depleting electrolytes, leading to hyponatremia. Therefore, the IV solution should include electrolyte replacement. Solutions like lactated Ringer's solution would usually be ordered. The other choices (B, C, and D) are appropriate for a postoperative patient with gastric suction, addressing pain management, nausea control, and correcting hyponatremia if it drops below a certain level.
Question 2 of 5
A patient who is lethargic and exhibits deep, rapid respirations has the following arterial blood gas (ABG) results: pH 7.32, PaO2 88 mm Hg, PaCO2 37 mm Hg, and HCO3 16 mEq/L. How should the nurse interpret these results?
Correct Answer: A
Rationale: The patient's pH is below the normal range (7.35-7.45), and the HCO3 is also below the normal range (22-26 mEq/L), indicating an acidic environment, which is consistent with metabolic acidosis. The ABGs provided do not support respiratory acidosis or alkalosis, as the PaCO2 is within the normal range (35-45 mm Hg) despite the patient's deep, rapid respirations. Therefore, the correct interpretation is metabolic acidosis.
Question 3 of 5
A nurse in the outpatient clinic is caring for a patient who has a magnesium level of 1.3 mg/dL. Which assessment would be most important for the nurse to make?
Correct Answer: A
Rationale: The correct answer is A: Daily alcohol intake. Hypomagnesemia is often associated with alcoholism, making it crucial for the nurse to assess the patient's alcohol consumption. Protein intake is not directly related to magnesium levels. The use of over-the-counter laxatives and multivitamin/mineral supplements would typically increase magnesium levels, which are not the focus when dealing with hypomagnesemia.
Question 4 of 5
The nurse is caring for a patient who has a central venous access device (CVAD). Which action by the nurse is appropriate?
Correct Answer: B
Rationale: The correct answer is B because using the push-pause method to flush the CVAD after giving medications helps remove debris from the CVAD lumen and decreases the risk for clotting. Choice A is incorrect because friction should be used when cleaning the CVAD insertion site to decrease infection risk. Choice C is incorrect because obtaining an order from the healthcare provider to change the CVAD dressing is not necessary; the dressing should be changed when damp, loose, or visibly soiled. Choice D is incorrect because the patient should face away from the CVAD during cap changes to minimize the risk of contamination.
Question 5 of 5
The nurse assesses a patient who has been hospitalized for 2 days. The patient has been receiving normal saline IV at 100 mL/hr, has a nasogastric tube to low suction, and is NPO. Which assessment finding would be a priority for the nurse to report to the health care provider?
Correct Answer: C
Rationale: The priority assessment finding for the nurse to report to the healthcare provider is a gradually decreasing level of consciousness (LOC). This change in LOC could indicate fluid and electrolyte disturbances, which require immediate attention to prevent complications. While the other options such as an elevated temperature, serum sodium level, and weight gain are important to note and report, they do not indicate an urgent need for intervention compared to changes in LOC which could signify serious issues that need prompt evaluation and management.
