ATI Pharmacology Assessment 2 Questions
Question 1 of 5
Local vasoconstriction is of short duration and can be prolonged by application of:
Correct Answer: C
Rationale: Thromboxane is a vasoconstrictor that is released by platelets during the process of blood clotting. Local vasoconstriction is a temporary response that occurs to reduce bleeding at the site of injury. Thromboxane plays a role in this process by constricting the blood vessels temporarily to limit blood flow to the injured area. By prolonging the application of thromboxane, vasoconstriction can be prolonged to support the clotting process and minimize bleeding. Adrenaline, steroids, heparin, and thrombin do not have the same vasoconstrictive properties as thromboxane.
Question 2 of 5
A patient is receiving tetracycline. Which advice should the nurse include when teaching this patient about tetracycline?
Correct Answer: A
Rationale: Tetracycline can cause photosensitivity, increasing the risk of severe sunburn. Patients should be advised to use sunscreen and avoid prolonged sun exposure. Taking antacids with tetracycline is contraindicated, as they can bind to the drug and reduce its absorption. Hearing loss and retinal damage are not associated with tetracycline use. Instead, patients should be monitored for gastrointestinal side effects and advised to take the medication with food if tolerated.
Question 3 of 5
The nurse assesses the patient receiving phentolamine (Regitine) and suspects what finding is an adverse effect of the medication?
Correct Answer: C
Rationale: Patients receiving phentolamine often experience extensions of the therapeutic effects, including hypotension, orthostatic hypotension, angina, myocardial infarction, cerebrovascular accident, flushing, tachycardia, and arrhythmia all of which are related to vasodilation and decreased blood pressure. Headache, weakness, and dizziness often occur in response to hypotension. Nausea, vomiting, and diarrhea may also occur. Hypertension, wheezing, and depressed respiration would not be associated with phentolamine. The nurse should monitor for adverse effects and intervene as needed.
Question 4 of 5
The nurse will be administering an antitussive medication containing codeine to a patient. What is the priority assessment?
Correct Answer: C
Rationale: Codeine, an opioid antitussive, can cause respiratory depression as a side effect. The nurse must assess the patient’s respiratory rate before administration to ensure it is within a safe range (typically >12 breaths per minute). While lung sounds (B) and sputum consistency (D) are important, they are not the priority when administering a medication that can suppress respiration. Pulse oximetry (A) is useful but secondary to direct respiratory rate assessment.
Question 5 of 5
Colchicine is prescribed for a client with gout. The nurse reviews the client’s record, knowing that this medication would be used in caution in which of the following medical conditions?
Correct Answer: B
Rationale: Colchicine should be used with caution in patients with aplastic anemia or other blood dyscrasias, as it can exacerbate bone marrow suppression. While colchicine is used to treat conditions like Behcet disease and familial Mediterranean fever, it is not contraindicated in these conditions. Amyloidosis is not a primary concern with colchicine use. Monitoring blood counts is essential in patients with pre-existing hematologic conditions.
