A nurse admitting a patient with a history of emphysema reviews her past lab reports and notes that the patient's PaCO2 has been 56 to 64 mmHg. The nurse will be cautious administering oxygen because:
- A. The patient's calcium will rise dramatically due to pituitary stimulation.
- B. The oxygen will increase the patient's intracranial pressure and create confusion.
- C. The oxygen may cause the patient to hyperventilate and become acidotic.
- D. Using oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.
Correct Answer: D

When selecting a site on the hand or arm for insertion of an IV catheter, the nurse should:
- A. Choose a proximal site.
- B. Choose a distal site.
- C. Have the patient hold his arm over his head.
- D. Leave the tourniquet on for at least 5 minutes.
Correct Answer: B
Rationale: When selecting a site for insertion of an IV catheter, the nurse should choose a distal site, not a proximal site. Selection of a distal site leaves the upper veins available for subsequent cannulations. Instruct the patient to hold his arm in a dependent position to increase blood flow. Never leave a tourniquet in place longer than 2 minutes.

A 65-year-old male patient was admitted to a medical-surgical unit 72 hours ago with pyloric stenosis; a nasogastric tube was inserted upon admission and has been on low intermittent suction since then. The nurse taking care of the patient notices that his potassium is very low and becomes concerned that the patient may be at risk for:
- A. Hypercalcemia
- B. Metabolic acidosis
- C. Metabolic alkalosis
- D. Respiratory acidosis
Correct Answer: C
Rationale: Probably the most common cause of metabolic alkalosis is vomiting or gastric suction with loss of hydrogen and chloride ions. The disorder also occurs in pyloric stenosis in which only gastric fluid is lost. Vomiting, gastric suction, and pyloric stenosis all remove potassium and can cause hypokalemia.
