Prior to administration of the initial dose of the gastrointestinal (GI) agent misoprostol, which information should the nurse obtain from the patient?

Taking an antiemetic medication.

Allergy to aspirin.

Currently pregnant.

History of glaucoma.

Answer and Explanation

The Correct Answer is C

A. Taking an antiemetic medication: This information is not directly relevant before administering misoprostol. Misoprostol does not typically interact with antiemetic medications in a way that would change the administration plan.
B. Allergy to aspirin: While important to know for general medication safety, misoprostol's primary concern is its potential effects on pregnancy rather than an allergy to aspirin.
C. Currently pregnant: Misoprostol is contraindicated in pregnancy due to its potential to induce uterine contractions and cause miscarriage. It is crucial to confirm that the patient is not pregnant before administering this medication.
D. History of glaucoma: While important for other medications, a history of glaucoma is not a primary concern when administering misoprostol.

Correct Answer is C

Explanation

A) Increases contractility: Metoprolol, a beta-blocker, actually decreases contractility. It reduces the force of contraction of the heart muscle, which can help reduce myocardial oxygen demand and improve outcomes after ACS. Increasing contractility would counteract the therapeutic goals of metoprolol in managing ACS.
B) Increases preload: Preload refers to the volume of blood in the ventricles at the end of diastole. Metoprolol does not increase preload; rather, it reduces myocardial workload and oxygen demand, which does not directly affect preload but rather the heart's performance overall.
C) Decreases afterload: Metoprolol reduces afterload indirectly by lowering blood pressure and decreasing heart rate, which helps reduce the workload on the heart. This reduction in afterload supports the therapeutic goals of metoprolol in managing ACS by decreasing the heart's work and improving cardiac efficiency.
D) Decreases diastolic filling time: Metoprolol slows the heart rate, which can lead to increased diastolic filling time, not a decrease. Increased filling time can be beneficial as it allows the heart more time to fill with blood between beats, thereby improving cardiac output.

A. Obtain a platelet count weekly. B. Take the medication during pregnancy. C. Use folic acid to protect the liver. D. Store the medication at room temperature.

Correct Answer is B

Explanation

A. Obtain a platelet count weekly: Regular monitoring of platelet counts is important for clients on methotrexate due to the risk of bone marrow suppression and potential thrombocytopenia. This instruction is appropriate and necessary.
B. Take the medication during pregnancy: Methotrexate is contraindicated during pregnancy due to its teratogenic effects and potential to cause fetal harm. It is crucial for clients to avoid using methotrexate while pregnant or planning to become pregnant.
C. Use folic acid to protect the liver: While folic acid is often used to help reduce the side effects of methotrexate, particularly its gastrointestinal effects and potential for liver toxicity, it is not used to "protect the liver" per se. The correct approach is to use folic acid as directed by a healthcare provider, often to mitigate some of the side effects of methotrexate.
D. Store the medication at room temperature: Methotrexate should be stored according to the manufacturer's instructions, which usually involve keeping it at room temperature. This information is correct and does not require additional instruction.
