ATI Capstone Pharmacology Assessment 1 and 2 Questions
Question 1 of 5
What is the evaluation of medication effectiveness of senna?
Correct Answer: C
Rationale: Senna is a stimulant laxative commonly used to treat constipation. Its effectiveness is primarily evaluated based on the production of soft, well-formed bowel movements. Senna works by stimulating the muscles in the intestines, promoting bowel movements and easing constipation. It is not typically used for reducing GI pain and irritation, healing ulcers, or preventing nausea and vomiting. Therefore, the evaluation of medication effectiveness of senna is primarily based on achieving soft, formed bowel movements in patients with constipation.
Question 2 of 5
Which patient-teaching instructions are appropriate for a patient taking an antidysrhythmic drug? (Select all that apply.)
Correct Answer: A
Rationale: A. Do not chew or crush extended-release forms of medication. - This instruction is important to ensure the medication is delivered in a controlled manner over an extended period.
Question 3 of 5
A patient is in the intensive care unit because of an acute myocardial infarction. He is experiencing severe ventricular dysrhythmias. The nurse will prepare to give which drug of choice for this dysrhythmia?
Correct Answer: C
Rationale: Amiodarone is the drug of choice for treating severe ventricular dysrhythmias, such as those seen in patients with acute myocardial infarction. It is effective in treating both ventricular tachycardia and ventricular fibrillation. Amiodarone works by prolonging the action potential duration and refractory period in cardiac tissues, thereby helping to stabilize the heart's electrical activity. Diltiazem and Verapamil are calcium channel blockers that are not typically used for treating ventricular dysrhythmias. Adenosine is primarily used for treating supraventricular tachycardias.
Question 4 of 5
The nurse practitioner has written a number of stat orders for drugs to treat a patient on the medical-surgical unit who has suffered an acute anaphylactic reaction with hives and bronchospasm during infusion of an IV antibiotic. Which priority drug would the nurse administer first?
Correct Answer: C
Rationale: Epinephrine is the first-line treatment for anaphylaxis due to its rapid action in reversing bronchospasm, vasodilation, and hypotension. It acts on alpha- and beta-adrenergic receptors to constrict blood vessels, relax bronchial smooth muscle, and increase cardiac output. Steroids (A) and diphenhydramine (D) are adjuncts to manage inflammation and histamine release but are not immediate lifesaving measures. Dopamine (B) is used for hypotension but is not the first-line treatment for anaphylaxis.
