The patient takes insulin for diabetes mellitus. The physician orders metoprolol (Lopressor) for hypertension. After medication teaching, the nurse determines that learning has occurred when the patient makes which statement?
1. "I might not need to check my blood sugars as often with metoprolol (Lopressor)."
2. "I might be able to change from insulin to a pill with metoprolol (Lopressor)."
3. "I might need less insulin when I take metoprolol (Lopressor)."
4. "I might need more insulin when I take metoprolol (Lopressor)."

Rationale 1: The patient will most likely need more frequent blood glucose assessments, as metoprolol (Lopressor) may enhance the hypoglycemic effects of insulin.
Rationale 2: Metoprolol (Lopressor) will not change a diabetic patient's need for insulin; the patient might just require less insulin.
Rationale 3: Metoprolol (Lopressor) may enhance the hypoglycemic effects of insulin and oral hypoglycemic agents, so the patient might require less insulin.
Rationale 4: Metoprolol (Lopressor) may enhance the hypoglycemic effects of insulin and oral hypoglycemic agents, so the patient might require less, not more, insulin.
Global Rationale: Metoprolol (Lopressor) may enhance the hypoglycemic effects of insulin and oral hypoglycemic agents, so the patient might require less insulin.

The nurse is providing care for a patient whose recent stroke has necessitated the use of a nasogastric tube for feeding while a longer-term solution is explored with the patient's family
In an effort to prevent aspiration, the nurse recognizes the need to accurately assess the tube's placement. How should this best be done? A) Mark the tube's exit point from the patient's nares after an X-ray. B) Aspirate 3 to 5 mL of fluid from the nasogastric tube and test the fluid's pH. C) Inject 5 to 10 mL of air into the nasogastric tube while auscultating the patient's abdomen. D) Aspirate some fluid from the tube and test the fluid for glucose using a testing strip.
