Question 1 of 5
What is the administration route of Ondansetron?
Correct Answer: D
Rationale: Ondansetron is typically administered orally, commonly in the form of tablets, orally disintegrating tablets, or liquid solution. The medication is absorbed through the gastrointestinal tract when taken orally, making it an effective route of administration for managing nausea and vomiting. SubQ (subcutaneous), sublingual, and buccal routes are not typical routes of administration for ondansetron.
Question 2 of 5
Drugs may be excreted by any route in the body, except:
Correct Answer: D
Rationale: Saliva is not a common route for drug excretion. Drugs are primarily excreted from the body through various routes such as the kidneys (urine), lungs (exhaled air), gastrointestinal tract (feces), and tears (through the eyes). Saliva does not play a major role in drug excretion, as most drugs are not significantly eliminated through saliva.
Question 3 of 5
For which serious adverse effect should the nurse closely monitor a patient who is taking lincosamides?
Correct Answer: D
Rationale: Lincosamides, such as clindamycin, are associated with a high risk of Clostridium difficile-associated diarrhea (CDAD), a potentially life-threatening condition. CDAD occurs due to the disruption of normal gut flora, allowing C. difficile to overgrow and produce toxins. Symptoms include severe diarrhea, abdominal pain, and fever. While lincosamides can rarely cause hepatotoxicity or ototoxicity, CDAD is the most common and serious adverse effect. Seizures are not typically associated with lincosamides. Early identification and treatment of CDAD are crucial to prevent complications like toxic megacolon or sepsis.
Question 4 of 5
A 5-year-old African American patient has been admitted to the pediatric intensive care unit with pheochromocytoma. The physician has ordered phentolamine. The nurse knows that the other indication for phentolamine is what?
Correct Answer: B
Rationale: Phentolamine (Regitine) is used for the prevention of cell death and tissue sloughing after extravasation of intravenous norepinephrine or dopamine, and severe hypertension reactions caused by manipulation of the pheochromocytoma before and during surgery; diagnosis of pheochromocytoma. Phentolamine would not be indicated for treatment of migraine headaches, life-threatening arrhythmias, or heart failure. The nurse should understand the indications for phentolamine to ensure safe and effective administration.
Question 5 of 5
As you are preparing morning medications, the patient says, 'I have had loose stools all night long.' Your patient has scheduled docusate at 0900. What is the priority action?
Correct Answer: A
Rationale: Docusate is a stool softener used to prevent constipation. If the patient is already experiencing loose stools, administering docusate could exacerbate the condition, leading to diarrhea or dehydration. The nurse should hold the medication and inform the healthcare provider to reassess the need for docusate. Increasing the IV flow rate (C) or the dose (D) is inappropriate in this situation.
