Question 1 of 5
A side e昀昀ect given o昀昀 by omeprazole is:
Correct Answer: B
Rationale: Omeprazole is a proton pump inhibitor commonly used to reduce stomach acid production. One of the side effects of omeprazole is a change in stomach pH. By inhibiting the proton pumps in the stomach lining, omeprazole reduces the production of acid, leading to an increase in the pH level of the stomach. This change in stomach pH can affect the overall balance of acidity in the stomach and may result in various gastrointestinal symptoms such as bloating, gas, or changes in digestion. It is important for individuals taking omeprazole to be aware of this potential side effect and consult their healthcare provider if they experience any unusual symptoms.
Question 2 of 5
When administering the anticoagulant drug Warfarin, what is one of the two lab tests you should monitor to distinguish the effectiveness of the drug?
Correct Answer: B
Rationale: When administering the anticoagulant drug Warfarin, one of the two lab tests you should monitor to distinguish the effectiveness of the drug is the International Normalized Ratio (INR). INR measures the time it takes for blood to clot and is used to monitor the effects of Warfarin therapy. The target INR range for patients on Warfarin therapy varies depending on the indication for treatment, but in general, a higher INR indicates that the blood is taking longer to clot, which means the Warfarin is working effectively to prevent blood clots. Regular monitoring of the INR levels is essential to ensure that patients are receiving an appropriate dose of Warfarin to prevent both clotting and bleeding complications.
Question 3 of 5
Action of anticholinergic drugs:
Correct Answer: A
Rationale: Atropine sulfate is an anticholinergic drug that antagonizes the action of acetylcholine at muscarinic receptors. By blocking the parasympathetic nervous system, atropine produces various effects including decreased salivation, increased heart rate, bronchodilation, and mydriasis (pupillary dilation). These properties make atropine useful in treating conditions such as bradycardia, poisoning with certain toxins, and for dilation of the pupil during eye exams.
Question 4 of 5
This describes the relationship of the blood concentration attained with initial dosing and the dose of drug given:
Correct Answer: D
Rationale: The volume of distribution (Vd) is a pharmacokinetic parameter that describes the relationship of the blood concentration attained with initial dosing and the dose of drug given. It is a theoretical volume that indicates the extent of drug distribution in the body relative to its concentration in the bloodstream. A high volume of distribution suggests that the drug is extensively distributed throughout the tissues of the body, while a low volume of distribution indicates that the drug is largely confined to the bloodstream. Therefore, Vd is the correct answer in this scenario.
Question 5 of 5
The nurse enters a patient’s room to find that his heart rate is 120, his blood pressure is 70/50, and he has red blotching of his face and neck. Vancomycin is running intravenous piggyback. The nurse believes that this patient is experiencing a severe adverse effect called red man syndrome. What action will the nurse take?
Correct Answer: A
Rationale: Red man syndrome is a hypersensitivity reaction to vancomycin, characterized by flushing, rash, hypotension, and tachycardia. The nurse should immediately stop the infusion to prevent further reaction and call the health care provider for further instructions. Reducing the infusion rate may help in mild cases, but in this severe case, stopping the infusion is the priority. Encouraging fluids is not appropriate for managing this acute reaction. Stevens-Johnson syndrome is a different, more severe condition and is not indicated by these symptoms.
