ATI Pharmacology Proctored Exam
1. A patient is receiving education about a new prescription for Omeprazole to manage heartburn. What information should the nurse include in the teaching?
- A. Take this medication at bedtime.
- B. This medication decreases the production of gastric acid.
- C. Take this medication 2 hours after eating.
- D. This medication can cause hyperkalemia.
Correct answer: B
Rationale: The correct information to include when teaching a patient about Omeprazole is that it decreases the production of gastric acid. Omeprazole works by inhibiting the proton pump in the stomach lining, thereby reducing acid secretion. This mechanism helps in managing heartburn symptoms effectively. Choice A is incorrect because Omeprazole is usually taken before a meal. Choice C is incorrect as Omeprazole is typically taken before meals, not after. Choice D is incorrect because hyperkalemia is not a common side effect of Omeprazole.
2. When providing discharge instructions to a client prescribed Warfarin, which herbal supplement should the nurse instruct the client to avoid?
- A. St. John's wort
- B. Echinacea
- C. Garlic
- D. Ginseng
Correct answer: A
Rationale: St. John's wort should be avoided by clients taking Warfarin as it can reduce the medication's effectiveness by interacting with its metabolism. While garlic and ginseng are also known to interact with Warfarin, the specific supplement the nurse should instruct the client to avoid in this scenario is St. John's wort. Echinacea, although an herbal supplement, is not typically associated with significant interactions with Warfarin and is not the primary concern in this case.
3. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
4. A healthcare provider is assessing a client who takes Desmopressin for Diabetes Insipidus. For which of the following adverse effects should the healthcare provider monitor?
- A. Hypovolemia
- B. Hypercalcemia
- C. Agitation
- D. Headache
Correct answer: D
Rationale: The correct answer is D: Headache. Headache during desmopressin therapy can indicate water intoxication, which is a potential adverse effect. Desmopressin is a medication used to treat Diabetes Insipidus by reducing excessive urination and thirst. Monitoring for headaches is crucial as it can signal decreased sodium levels due to water retention, leading to water intoxication, which is a serious concern. Hypovolemia, hypercalcemia, and agitation are not typically associated with desmopressin therapy for Diabetes Insipidus.
5. A client informs the nurse that she has difficulty swallowing tablets and struggles with liquid or chewable medications due to taste. What medication should the nurse request a prescription for when preparing to administer Penicillin V to treat the client's streptococcal infection?
- A. Fosfomycin
- B. Amoxicillin
- C. Nafcillin
- D. Cefaclor
Correct answer: C
Rationale: Nafcillin is an appropriate alternative within the penicillin class for clients who have difficulty swallowing tablets or struggle with liquid or chewable medications. It is available for intramuscular (IM) or intravenous (IV) administration, offering options beyond oral formulations. Fosfomycin, Amoxicillin, and Cefaclor are not suitable alternatives for Penicillin V in this scenario as they belong to different classes of antibiotics and may not be as effective in treating streptococcal infections.
