Reduces gastric acid secretion

Enhances gastrointestinal motility

Relieves abdominal pain

Acts as an antiemetic by inhibiting serotonin

Answer and Explanation

The Correct Answer is B

A. While metoclopramide may have some effect on gastric acid secretion, its primary role is not to reduce it.

B. Metoclopramide primarily enhances gastrointestinal motility, which helps to facilitate gastric emptying and is especially useful in treating conditions like gastroparesis.

C. Metoclopramide does not specifically relieve abdominal pain; it focuses more on motility and nausea.

D. Although metoclopramide does have antiemetic properties, it primarily acts as a dopamine receptor antagonist rather than directly inhibiting serotonin.

Correct Answer is A

Explanation

A. An INR of 5.0 indicates a significantly increased risk of bleeding, and administering vitamin K is the appropriate antidote for reversing the effects of warfarin. This is a critical intervention to restore coagulation.

B. Increasing the dose of warfarin is inappropriate in this scenario because the INR is already elevated; it would further increase bleeding risk.

C. While heparin can be used for anticoagulation, it is not appropriate to administer it while the INR is dangerously high without reversing the warfarin first.

D. Continuing warfarin is unsafe at this INR level due to the high risk of bleeding; monitoring for symptoms without intervention is not adequate care.

A. History of hypertension B. Presence of a dry cough C. Recent use of antibiotics D. History of seizures

Correct Answer is A

Explanation

A. Pseudoephedrine is a decongestant that can raise blood pressure and cause increased heart rate, so it is essential to assess the patient’s history of hypertension before starting this medication.

B. While a dry cough may be relevant for other medications, it is not a primary concern when assessing for the use of pseudoephedrine.

C. Recent use of antibiotics is not directly related to the safety of using pseudoephedrine and is not a typical concern.

D. A history of seizures is not a specific contraindication for using pseudoephedrine, although it may warrant caution in some cases.
