Question 1 of 5
Route of drug administration where the drug is placed directly into the GIT from where absorption occurs.
Correct Answer: A
Rationale: Enteral route of drug administration involves placing the drug directly into the gastrointestinal tract (such as oral or rectal routes) for absorption into the systemic circulation. This route requires the drug to pass through the digestive system before being absorbed, allowing for slower and more sustained release of the medication compared to other routes. Examples of enteral drug administration include oral tablets, capsules, and liquids as well as rectal suppositories.
Question 2 of 5
Which route should lithium be administered by?
Correct Answer: A
Rationale: Lithium is typically administered orally (PO) for long-term treatment of bipolar disorder. However, in emergency situations or cases of lithium toxicity where rapid control of symptoms is required, lithium can be administered via the intravenous (IV) route for faster absorption and effectiveness. IV administration allows for quick delivery of the medication directly into the bloodstream to achieve therapeutic levels promptly. It is essential to closely monitor lithium levels and kidney function when administering it intravenously to prevent potential complications.
Question 3 of 5
A patient is admitted to the hospital with multidrug-resistant urinary tract infection. Laboratory tests show Pseudomonas aeruginosa. Colistimethate sodium is ordered by intramuscular injection. The nurse understands that which of the following is the purpose for this drug?
Correct Answer: B
Rationale: Colistimethate sodium is a polymyxin antibiotic used to treat multidrug-resistant Gram-negative infections, including Pseudomonas aeruginosa. It is not safe for patients with renal impairments and does not prevent antibiotic resistance. Its primary purpose is to treat infections caused by resistant Gram-negative bacteria.
Question 4 of 5
Route of drug administration where the drug is placed directly into the GIT from where absorption occurs.
Correct Answer: A
Rationale: Enteral route of drug administration involves placing the drug directly into the gastrointestinal tract (such as oral or rectal routes) for absorption into the systemic circulation. This route requires the drug to pass through the digestive system before being absorbed, allowing for slower and more sustained release of the medication compared to other routes. Examples of enteral drug administration include oral tablets, capsules, and liquids as well as rectal suppositories.
Question 5 of 5
The nurse is reviewing discharge teaching for a patient who will be taking digoxin (Lanoxin) therapy. The nurse will teach the patient to avoid which foods when taking the digoxin?
Correct Answer: A
Rationale: Consuming high amounts of foods rich in potassium, such as leafy green vegetables, can potentially decrease the effectiveness of digoxin. Digoxin works by helping the heart beat more strongly and regularly, but too much potassium in the body can interfere with its action. Therefore, patients taking digoxin are usually advised to avoid consuming excessive amounts of foods high in potassium, such as leafy green vegetables. It is recommended for patients on digoxin therapy to maintain a consistent level of potassium in their diet and follow their healthcare provider's guidance on dietary restrictions.
