The patient receives metaproterenol (Alupent), an adrenergic drug. A consulting physician orders carteolol (Cartrol), a beta blocker. What best describes the nurse's assessment?
1. The patient is at risk for a hypertensive crisis.
2. The effects of metaproterenol (Alupent) will be decreased.
3. The drugs are compatible; there will not be any adverse effects.
4. The effects of metaproterenol (Alupent) will be increased.
Correct Answer: 2
Rationale: Beta-adrenergic blockers block the receptors that are stimulated by adrenergic drugs; the effects of metaproterenol (Alupent) would be decreased, not increased. The drugs are not compatible; the effects of metaproterenol (Alupent) would be decreased. A hypertensive crisis is unlikely.
