ATI Capstone Pharmacology Assessment 1 and 2 Questions
Question 1 of 5
What is important to monitor when giving the drug Phenytoin?
Correct Answer: D
Rationale: When giving the drug Phenytoin, monitoring urinary pH is important because Phenytoin is known to be excreted by the kidneys. Changes in urinary pH can affect the concentration of Phenytoin in the body. Alkaline urine can increase the excretion of Phenytoin, potentially leading to subtherapeutic levels, while acidic urine can decrease excretion, potentially leading to toxic levels of the drug.
Therefore, monitoring urinary pH helps ensure that Phenytoin levels are within the therapeutic range, minimizing the risk of either subtherapeutic or toxic effects. Monitoring for signs of toxicity, such as ataxia, nystagmus, and confusion, is also essential when administering Phenytoin.
Question 2 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.
Question 3 of 5
A patient in the outpatient oncology clinic has developed mucositis after receiving fluorouracil. Which statement made by the patient indicates the need for additional teaching about mucositis?
Correct Answer: C
Rationale: Mucositis, inflammation of the mucous membranes, is a common side effect of chemotherapy. Using alcohol-based mouthwash can exacerbate mucositis by causing further irritation and dryness. The patient should be taught to use gentle, non-alcoholic mouth rinses, such as saline or baking soda solutions, to soothe the mucosa. Ice pops, ice chips, and a soft toothbrush are appropriate measures to manage mucositis. The nurse should provide additional teaching to correct the misconception about alcohol-based mouthwash and emphasize the importance of gentle oral care.
Question 4 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 5 of 5
A patient is receiving an IV infusion of a thrombolytic drug during treatment for an acute MI. The nurse notices that there is a slight amount of bleeding from the antecubital area where venous lab work was drawn. What will the nurse do first?
Correct Answer: B
Rationale: In this situation, the nurse's first priority should be to apply pressure to the site with a gauze pad. Bleeding from the antecubital area where venous lab work was drawn can be due to the effect of the thrombolytic drug, particularly in a patient who is already at risk for bleeding due to the acute MI. Applying pressure to the site will help control the bleeding and prevent any further complications. Once the bleeding is controlled, the nurse should monitor the site closely for any signs of increased bleeding or other complications. Slowing the rate of infusion or stopping the infusion of the thrombolytic drug may be considered depending on the severity of the bleeding and the patient's overall condition, but the immediate response should be to apply pressure to the site.
