1. A patient who is hospitalized with a possible electrolyte imbalance is disoriented and weak, has an irregular pulse, and takes hydrochlorothiazide. He most likely suffers from:

Correct answer: D

Rationale: The patient is displaying symptoms of hypokalemia, including weakness, disorientation, irregular pulse, which can lead to cardiac disturbances. Hydrochlorothiazide is a potassium-wasting diuretic that can cause hypokalemia if not accompanied by potassium replacement therapy. Hypernatremia (choice A) is characterized by high sodium levels, not potassium. Hyponatremia (choice B) is low sodium levels. Hyperkalemia (choice C) is high potassium levels, which is not consistent with the symptoms described in the question.

2. The healthcare professional working in the PACU is aware that which of the following procedures may contribute to extracellular losses?

Correct answer: C

Rationale: Fluid loss from the extracellular compartment can be caused by abdominal surgery as it involves opening the abdominal cavity, potentially leading to significant fluid losses. Choices A, B, and D do not typically result in substantial extracellular losses compared to abdominal surgery.

3. You are caring for a patient admitted with a diagnosis of acute kidney injury. When you review your patient's most recent laboratory reports, you note that the patient's magnesium levels are high. You should prioritize assessment for which of the following health problems?

Correct answer: A

Rationale: Corrected Rationale: To assess a patient's magnesium status, the nurse should check deep tendon reflexes. Diminished deep tendon reflexes may indicate high serum magnesium levels, as hypermagnesemia can lead to neuromuscular effects. Tachycardia, cool clammy skin, and acute flank pain are not typically associated with high magnesium levels and are not priority assessments in this situation.

4. A nurse in the neurologic ICU has orders to infuse a hypertonic solution into a patient with increased intracranial pressure. This solution will increase the number of dissolved particles in the patients blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. This process is best described as which of the following?

Correct answer: B

Rationale:

5. . A 73-year-old man comes into the emergency department (ED) by ambulance after slipping on a small carpet in his home. The patient fell on his hip with a resultant fracture. He is alert and oriented; his pupils are equal and reactive to light and accommodation. His heart rate is elevated, he is anxious and thirsty, a Foley catheter is placed, and 40 mL of urine is present. What is the nurses most likely explanation for the low urine output?

Correct answer: D

Rationale:
