ATI Capstone Pharmacology Assessment 2 Questions
Question 1 of 5
A client is prescribed fluoxetine (Prozac) for depression. Which statement by the client indicates a need for further teaching?
Correct Answer: B
Rationale: Fluoxetine, an SSRI, treats depression but interacts with alcohol, worsening sedation or mood , indicating a teaching gap'clients must avoid it. Feeling better in weeks aligns with SSRI onset. Reporting suicidal thoughts is critical due to early risk. Morning dosing prevents insomnia. Drinking wine risks treatment failure or safety issues, critical in depression where stability is fragile. Further teaching must clarify this interaction, ensuring fluoxetine's efficacy and client well-being, making B the statement needing correction.
Question 2 of 5
Which assessment finding, by the nurse, is a priority concern when a client receives pseudoephedrine (Sudafed)?
Correct Answer: C
Rationale: Pseudoephedrine, an oral decongestant, stimulates alpha-adrenergic receptors, potentially causing cardiovascular effects like dysrhythmias due to its sympathomimetic action. An irregular heart rate of 82 is a priority concern, signaling possible arrhythmia, which could escalate to serious cardiac events, requiring immediate reporting. A mild fever or elevated respiratory rate could relate to the underlying condition (e.g., infection) rather than the drug. Dry mouth is a common, benign side effect. The nurse focuses on the irregular pulse as it aligns with pseudoephedrine's known risk of dysrhythmias, especially in susceptible patients, making choice C the most urgent finding to address.
Question 3 of 5
Heparin:
Correct Answer: D
Rationale: Heparin is an anticoagulant that enhances the activity of antithrombin III, a natural inhibitor of thrombin and factor Xa, to prevent clotting. The statement that it inhibits clotting by decreasing antithrombin III effects is false, as heparin actually potentiates antithrombin III, making this the incorrect option. Its oral bioavailability is negligible (not 20-30%), as it's a large polysaccharide requiring parenteral administration (e.g., IV or subcutaneous), so this is false. Heparin is highly plasma protein-bound, not low, contradicting that option. The correct statement, replaced in the fourth slot, is that heparin binds to antithrombin III, causing a conformational change that accelerates its anticoagulant effect. This mechanism is fundamental to its clinical use in thrombosis prevention, distinguishing it from oral anticoagulants like warfarin.
Question 4 of 5
For the patient who is taking nalbuphine, what should the nurse do? (Select all that apply.)
Correct Answer: D
Rationale: Nalbuphine is an opioid agonist-antagonist used for pain management. Like other opioids, it can cause respiratory depression, so monitoring respirations is critical. Bradycardia is another potential side effect that patients should report. Administering nalbuphine undiluted is not standard practice, as it can increase the risk of adverse reactions. Excessive urine output is not associated with nalbuphine use. Therefore, the nurse should focus on monitoring respirations and educating the patient to report bradycardia.
Question 5 of 5
Upon preparing to administer activated charcoal by mouth to treat a patient who took an overdose of aspirin and several unknown drugs, the nurse notes that the patient has become very somnolent and eyes open only to a noxious stimulus. Which action by the nurse is most appropriate at this point?
Correct Answer: A
Rationale: The patient's decreased level of consciousness (somnolence and only responding to noxious stimuli) indicates a potential deterioration in their condition, possibly due to the overdose. Activated charcoal is contraindicated in patients with an altered mental status due to the risk of aspiration. The nurse should immediately consult the nurse practitioner to reassess the patient's condition and determine the appropriate intervention, such as securing the airway or considering alternative treatments.
