1. What can cause dehydration?

• A. Prolonged vomiting.
• B. Prolonged diarrhea.
• C. Too little fluid intake.
• D. Prolonged vomiting, diarrhea, and too little fluid intake.

Correct answer: D

Rationale: Dehydration can result from significant fluid loss due to vomiting, diarrhea, or inadequate fluid intake. Prolonged vomiting and diarrhea lead to excessive fluid loss from the body, contributing to dehydration. Similarly, not consuming enough fluids can also result in dehydration. Choice A and B are too specific as they only mention one cause each, while choice C is also correct but does not encompass all the potential causes of dehydration as mentioned in choice D.

2. You are caring for a patient admitted with a diagnosis of acute kidney injury. When you review your patients most recent laboratory reports, you note that the patients magnesium levels are high. You should prioritize assessment for which of the followin

• A. Diminished deep tendon reflexes
• B. Tachycardia
• C. Cool, clammy skin
• D. Acute flank pain

Correct answer: A

Rationale:

3. A nurse assesses a client who was started on intraperitoneal therapy 5 days ago. The client reports abdominal pain and feeling warm. For which complication of this therapy should the nurse assess this client?

• A. Allergic reaction
• B. Bowel obstruction
• C. Catheter lumen occlusion
• D. Infection

Correct answer: D

Rationale:

4. You are caring for a patient with a diagnosis of pancreatitis. The patient was admitted from a homeless shelter and is a vague historian. The patient appears malnourished and on day 3 of the patients admission total parenteral nutrition (TPN) has been started. Why would you know to start the infusion of TPN slowly?

• A. Patients receiving TPN are at risk for hypercalcemia if calories are started too rapidly.
• B. Malnourished patients receiving parenteral nutrition are at risk for hypophosphatemia if calories are started too aggressively.
• C. Malnourished patients who receive fluids too rapidly are at risk for hypernatremia.
• D. Patients receiving TPN need a slow initiation of treatment in order to allow digestive enzymes to accumulate

Correct answer: B

Rationale:

5. Your patient has the following arterial blood gas results: pH 7.26, PaCO2 28, HCO3 11 mEq/L. How would the nurse interpret the results?

• A. Respiratory acidosis with no compensation
• B. Metabolic alkalosis with a compensatory alkalosis
• C. Metabolic acidosis with no compensation
• D. Metabolic acidosis with a compensatory respiratory alkalosis

Correct answer: D

Rationale: The given arterial blood gas results show a low pH, indicating acidosis, with normal pH range being 7.35 to 7.45. The low PaCO2 suggests alkalosis, while the low bicarb level indicates acidosis. In this scenario, the primary issue is the metabolic acidosis, as the pH bicarb relationship supports this. The compensatory response to metabolic acidosis is a decrease in PaCO2, leading to a respiratory alkalosis. Therefore, the correct interpretation is 'Metabolic acidosis with a compensatory respiratory alkalosis.' Choices A, B, and C are incorrect as they do not accurately reflect the relationship between the pH, PaCO2, and HCO3 levels in the arterial blood gas results provided.
