ATI Capstone Pharmacology Assessment 2 Quizlet Questions
Question 1 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.
Question 2 of 5
Graded dose-response curves are most useful for determining
Correct Answer: A
Rationale: Graded dose-response curves plot individual response intensity to dose increases (e.g., pain relief), a pharmacodynamic tool. Population curves (e.g., ED50) suit groups, not individuals. Large or small groups aggregate data, missing individual nuance. Individual focus defines graded curves, key for tailoring therapy.
Question 3 of 5
A 74-year-old professional golfer has chest pain that occurs toward the end of his golfing games. He says the pain usually goes away after one or two sublingual nitroglycerin tablets and rest. What type of angina is he experiencing?
Correct Answer: D
Rationale: The 74-year-old professional golfer is likely experiencing Prinzmetal™s angina, also known as variant angina. This type of angina is characterized by episodes of chest pain that occur at rest or during minimal physical exertion. It is caused by a spasm in the coronary arteries, leading to a temporary reduction or cessation of blood flow to the heart muscle. The chest pain associated with Prinzmetal™s angina can be severe and is often relieved by sublingual nitroglycerin, as described by the golfer. Additionally, the fact that the pain occurs towards the end of his golfing games suggests that it may be triggered by stress or exertion, common triggers for coronary artery spasm in Prinzmetal's angina.
Question 4 of 5
Albuterol can be given in all but which of these forms:
Correct Answer: C
Rationale: Albuterol is a bronchodilator medication commonly used to treat bronchospasm in conditions such as asthma and chronic obstructive pulmonary disease (COPD). Albuterol can be given in various forms, including extended-release tablets for oral use, inhalation solutions for nebulization, and oral syrups. However, albuterol is not typically administered intravenously because it can cause severe cardiovascular side effects, such as tachycardia and arrhythmias, when given directly into the bloodstream. For this reason, intravenous administration of albuterol is contraindicated in most cases and is not a common route of administration for this medication.
Question 5 of 5
A 48-year-old woman with 2-year history of rheumatoid arthritis has not had sufficient relief with methotrexate alone. Her physician prescribes a biologic TNF-α inhibitor that consists of a recombinant human IgG fused to TNF-α receptor. Which of the following drugs is this?
Correct Answer: C
Rationale: Rheumatoid arthritis (RA) progression despite methotrexate warrants a TNF-α inhibitor. The description-recombinant human IgG fused to TNF-α receptor-points to Etanercept . Adalimumab and Golimumab are monoclonal antibodies against TNF-α, not receptor fusions. Certolizumab is a PEGylated Fab fragment, not IgG-based. Etanercept , a fusion protein, binds TNF-α, neutralizing it, and matches the question's structure. Infliximab (E) is a chimeric antibody. Etanercept's unique receptor-IgG design distinguishes it, effectively reducing RA inflammation by sequestering TNF-α, a key cytokine, making it the precise answer here.
