ATI Capstone Pharmacology Assessment 2 Quizlet Questions
Question 1 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 (CDA
D), 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 2 of 5
The physician ordered a brand name drug for the client, paroxetine (Paxil). After taking this medication for a year, the client tells the nurse that it is no longer working. What is the best assessment of the nurse at this time?
Correct Answer: B
Rationale: Paroxetine's effectiveness waning after a year suggests possible drug interactions reducing its levels or efficacy, a common issue needing assessment via medication review. Needing a change assumes a conclusion without evidence. Paxil and paroxetine are the same (brand vs. generic), making that question moot. Beck assessment evaluates depression, not drug failure. Interactions align with pharmacokinetic principles, offering a proactive step to identify culprits like enzyme inducers, critical for adjusting therapy.
Question 3 of 5
Which of the following types of insulin is “long-acting�
Correct Answer: D
Rationale: Glargine insulin, commonly known by the brand name Lantus, is a long-acting type of insulin. It is designed to provide a steady level of insulin over an extended period, usually lasting up to 24 hours. This type of insulin is often used as a basal insulin to help control blood sugar levels between meals and overnight. In contrast, Lispro (Humalog) is a rapid-acting insulin used to manage blood sugar spikes after meals, NPH (Humulin N) is an intermediate-acting insulin, and Regular insulin (Humulin R) is a short-acting insulin.
Question 4 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 5 of 5
The physician has prescribed haloperidol (Haldol) for the patient with schizophrenia. What is the priority patient outcome?
Correct Answer: B
Rationale: Haloperidol, a conventional antipsychotic, treats schizophrenia by reducing positive symptoms like hallucinations, but its efficacy depends on adherence. The priority outcome is medication compliance, as relapse is common without consistent use, undermining all other goals. Adequate fluids and fiber mitigate side effects (e.g., constipation) but are secondary to ensuring treatment continuity. Decreased hallucinations is a desired effect, not an outcome ensuring it happens. Restlessness indicates side effects (e.g., akathisia), not a goal. Compliance is foundational, as schizophrenia's chronic nature requires long-term management, making choice B the nurse's primary focus for successful therapy.
