In order to effectively provide appropriate patient teaching regarding the effects of psychotropic medications, an advanced practice nurse with prescriptive privileges is required to have a thorough understanding of which drug-related topic?

Correct Answer: A

Rationale: In 2003 the National Organization of Nurse Practitioner Faculties (NONPF) published a comprehensive set of competencies defining the scope and practice of psychiatric mental health nurse practitioners (PMHNPs). An example of a competency specific to medication prescribing for PMHNPs states that the PMHNP “prescribes psychotropic and related medications based on clinical indicators of a patient’s status, including results of diagnostic and lab tests as appropriate, to treat symptoms of psychiatric disorders and improve functional health status.” Knowledge of pharmacology algorithms or of monotherapeutic symptoms is not applicable since they are not required needs. A knowledge of the doses of all “atypical” psychotropic drugs is too specific to one class of psychotropic medications. Nurses need to know information about all psychotropic medications.

Correct Answer: C

Rationale: In this scenario, the correct answer is C) Stimulants. The patient's symptoms align with the effects of stimulant drugs like amphetamines or cocaine. These substances typically cause restlessness, hyperactivity, talkativeness, confusion, euphoria, tachycardia, and fever due to their stimulant properties on the central nervous system. Option A) Opioids are unlikely as opioids typically present with symptoms like respiratory depression, pinpoint pupils, sedation, and constipation, which are not consistent with the patient's symptoms. Option B) Alcohol intoxication would manifest with symptoms such as slurred speech, impaired coordination, sedation, and potentially respiratory depression, which do not match the patient's presentation. Option D) Depressants like benzodiazepines or barbiturates would result in symptoms such as sedation, decreased heart rate, respiratory depression, and impaired coordination, which are contradictory to the patient's hyperactive state. Educationally, understanding the distinct effects of different drug classes is crucial for healthcare professionals to accurately assess and manage patients presenting with substance-related symptoms. Recognizing the signs of stimulant intoxication, as in this case, enables appropriate interventions and ensures patient safety.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Atrial fibrillation. Ibutilide (Corvert) is a class III antiarrhythmic medication commonly used to treat atrial fibrillation. Atrial fibrillation is a common cardiac arrhythmia characterized by rapid and irregular atrial contractions, leading to inefficient blood pumping by the heart. Ibutilide works by prolonging the refractory period of the atria, helping to restore normal sinus rhythm in patients with atrial fibrillation. Option A) Ventricular ectopy is incorrect because ibutilide is not typically used to treat ventricular arrhythmias. Ventricular ectopy refers to premature contractions originating in the ventricles. Option C) Supraventricular tachycardia is incorrect because while ibutilide can be used for certain types of supraventricular arrhythmias, it is more commonly indicated for atrial fibrillation. Option D) Bradycardia is incorrect because ibutilide is not used to treat slow heart rates (bradycardia); it is more commonly used for fast or irregular heart rhythms. Understanding the specific indications for medications like ibutilide is crucial for nurses caring for patients with cardiovascular disorders. Recognizing the appropriate use of medications based on the patient's diagnosis is essential for safe and effective pharmacological management in clinical practice.

Correct Answer: A

Rationale: In this scenario, the nurse's best response is option A) “This is an expected adverse effect. Let me take your pulse.” This response is correct because feeling slightly nervous after receiving a nebulizer treatment with a beta agonist is a common side effect of beta agonists due to their stimulatory effect on the beta receptors. By acknowledging this as an expected adverse effect and checking the patient's pulse, the nurse can assess the patient's response to the medication and determine if any further intervention is necessary. Option B) “The next scheduled nebulizer treatment will be skipped” is incorrect because skipping a scheduled treatment without proper assessment and evaluation can potentially compromise the patient's asthma management and lead to worsening symptoms. Option C) “I will notify the physician about this adverse effect” is not the best initial response because the nurse should first assess the patient's condition and provide immediate care or intervention as needed before escalating the issue to the physician. Option D) “We will hold the treatment for 24 hours” is also incorrect as it does not address the immediate concern of the patient feeling nervous and does not follow standard practice guidelines for managing side effects of beta agonists. Educationally, this question highlights the importance of recognizing common side effects of medications, assessing patient responses, and providing appropriate patient education and support in managing these effects. It emphasizes the role of nurses in monitoring patients, providing reassurance, and taking necessary actions to ensure patient safety and well-being in pharmacological interventions.

Correct Answer: D

Rationale: In pharmacology, the volume of distribution (Vd) is a crucial concept that helps us understand how a drug is distributed throughout the body. The correct answer, D) The amount of a drug in the body to the concentration of a drug in plasma, is the most appropriate choice because Vd is a pharmacokinetic parameter that expresses the relationship between the total amount of drug in the body and the concentration of the drug in the plasma. Option A) Single to a daily dose of an administrated drug is incorrect because Vd is not specifically related to the dosing frequency but rather to the distribution of the drug in the body. Option B) An administrated dose to body weight is incorrect because Vd is not solely based on body weight but considers various factors such as tissue permeability, lipid solubility, and protein binding that affect drug distribution. Option C) An uncharged drug reaching the systemic circulation is incorrect because Vd does not specifically pertain to the charge state of the drug but rather focuses on the relationship between drug concentration in plasma and the total amount of drug in the body. Understanding Vd is essential in pharmacology as it can influence dosing regimens, drug efficacy, and potential for toxicity. By grasping this concept, healthcare professionals can make informed decisions regarding drug administration and monitoring to optimize patient outcomes.
