Question 1 of 5
Which class of targeted therapy would cause the nurse the most concern in regard to a possible infusion reaction?
Correct Answer: C
Rationale: Monoclonal antibodies, such as trastuzumab and rituximab, are more likely to cause infusion reactions compared to other classes of targeted therapy. These reactions can range from mild symptoms like fever and chills to severe anaphylaxis. Tyrosine kinase inhibitors, multikinase inhibitors, and proteasome inhibitors are less commonly associated with infusion reactions. The nurse should closely monitor patients receiving monoclonal antibodies during infusion and be prepared to manage any adverse reactions promptly.
Question 2 of 5
What type of diuretic is furosemide?
Correct Answer: A
Rationale: Furosemide is a loop diuretic. Loop diuretics act on the thick ascending limb of the loop of Henle in the kidney to inhibit sodium and chloride reabsorption, leading to increased excretion of water and electrolytes such as potassium and calcium. Loop diuretics are potent and are often used to treat conditions like edema, heart failure, and hypertension. Furosemide is commonly utilized to manage conditions such as congestive heart failure, high blood pressure, and edema associated with certain medical conditions.
Question 3 of 5
What is the most important patient/family teaching for patients that are taking Digoxin
Correct Answer: D
Rationale: The most important patient teaching for patients taking Digoxin is to regularly monitor and take their pulse. Digoxin is a medication used to treat certain heart conditions by helping the heart beat stronger and more regularly. Monitoring the pulse is important because Digoxin can affect the heart rate, and if the pulse is too slow or irregular, it may indicate an adverse reaction to the medication. Patients should be taught how to check their pulse and to contact their healthcare provider if they notice any significant changes in their heart rate while taking Digoxin. Taking the pulse is crucial in ensuring the medication is being tolerated well and is working effectively.
Question 4 of 5
The nurse is caring for a client receiving isoniazid (INH) for tuberculosis. Which instruction should the nurse include?
Correct Answer: C
Rationale: Isoniazid treats TB but risks hepatotoxicity, causing jaundice (yellowing skin, choice C), a serious sign needing immediate reporting to prevent liver failure. Food is optional'INH can be taken either way. Tyramine relates to MAOIs, not INH. Bedtime isn't specific'dosing is flexible. Reporting jaundice aligns with INH's side effect profile, critical in TB therapy where long-term use is common, making C the essential instruction for early detection and safety.
Question 5 of 5
Group of drugs which acts on amixed group of receptors:
Correct Answer: A
Rationale: Mixed agonist-antagonist drugs exhibit both agonistic and antagonistic properties at different receptor sites. These drugs can act as agonists at certain receptors while acting as antagonists at other receptors. This classification of drugs is distinct from pure agonists, pure antagonists, or partial agonists, as mixed agonist-antagonist drugs have a more complex mechanism of action. An example of a mixed agonist-antagonist drug is buprenorphine, which acts as a partial agonist at the mu opioid receptor and an antagonist at the kappa opioid receptor.
