Practice ATI B Exam Pharmacology Questions
Question 1 of 5
When teaching a patient who is beginning antilipemic therapy about possible drug-food interactions, the nurse will discuss which food?
Correct Answer: B
Rationale: Grapefruit juice can interact with antilipemic medications, specifically statins, causing increased drug levels in the bloodstream. This can lead to a higher risk of side effects and adverse reactions. Therefore, patients on antilipemic therapy should be cautious about consuming grapefruit juice to prevent potential drug interactions.
Question 2 of 5
Mannitol (Osmitrol), an osmotic diuretic, is contraindicated to which conditions? Select all that apply.
Correct Answer: B
Rationale: Mannitol (Osmitrol), an osmotic diuretic, is contraindicated in narrow-angle glaucoma. This is because mannitol can increase intraocular pressure, exacerbating the condition and potentially leading to vision complications. Options A, C, and D are incorrect because mannitol is actually indicated for these conditions. Pulmonary edema can be managed with mannitol to reduce intracranial pressure. In heart failure, mannitol can help reduce edema by increasing urine output. In chemotherapy, mannitol is used to prevent kidney damage by promoting diuresis. In an educational context, understanding contraindications of medications is crucial for safe and effective patient care. Pharmacological knowledge helps nurses and healthcare professionals make informed decisions to prevent adverse reactions and ensure optimal patient outcomes. Learning about contraindications also involves understanding the underlying mechanisms and effects of medications on different body systems.
Question 3 of 5
If a patient is taking an ACE inhibitor, the nurse should monitor for signs of angioedema which include?
Correct Answer: B
Rationale: Angioedema is a potential adverse effect of ACE inhibitors. It is a serious condition involving swelling of the deeper layers of the skin and subcutaneous tissue, including the mucous membranes. Signs of angioedema can include swelling of the face, lips, tongue, or throat, which can lead to difficulty breathing (dyspnea) due to airway obstruction. It is important for the nurse to monitor for these signs and symptoms, as angioedema can be life-threatening and requires immediate medical attention. Vomiting, constipation, and epistaxis are not typical signs of angioedema associated with ACE inhibitors.
Question 4 of 5
When administering the drug lithium, name one important side effect to watch for:
Correct Answer: B
Rationale: One important side effect to watch for when administering the drug lithium is seizures. Lithium is commonly used to treat bipolar disorder, but it can lower the seizure threshold and increase the risk of seizures in some patients. It is crucial to monitor individuals taking lithium for any signs of seizures or seizure activity and to promptly address any such occurrences. Regular monitoring of lithium levels and adjusting the dosage as necessary can help minimize the risk of seizures in patients receiving this medication.
Question 5 of 5
What's the normal range for therapeutic serum digoxin levels?
Correct Answer: A
Rationale: The normal range for therapeutic serum digoxin levels is typically considered to be 0.5-2 ng/mL. This range is where the drug digoxin effectively treats heart conditions such as atrial fibrillation and heart failure without causing toxicity. Levels below 0.5 ng/mL may be subtherapeutic, while levels above 2 ng/mL can lead to digoxin toxicity, characterized by symptoms like nausea, vomiting, visual disturbances, and cardiac arrhythmias. Regular monitoring of serum digoxin levels is essential to ensure the drug is being used safely and effectively.
