Question 1 of 5
The nurse is caring for a client receiving amitriptyline (Elavil) for depression. Which assessment finding requires immediate attention?
Correct Answer: C
Rationale: Amitriptyline, a tricyclic antidepressant, has anticholinergic effects, including urinary retention , a medical emergency risking bladder damage or infection, needing immediate intervention. Dry mouth and constipation are common, manageable side effects. Drowsiness is expected with its sedative action. Urinary retention's severity'potential for acute retention'sets it apart, requiring rapid reporting or catheterization. This aligns with amitriptyline's blockade of muscarinic receptors, where bladder dysfunction can escalate fast, making C the finding demanding urgent attention over chronic annoyances.
Question 2 of 5
The application of drugs for the purpose of treating diseases and treatment of suffering is known as
Correct Answer: B
Rationale: Pharmacotherapeutics applies drugs to treat diseases and alleviate suffering, combining pharmacology and therapeutic intent, a precise term. Biologics are drug types, not application. Alternative therapies use non-drug methods. Therapeutics is broader, but pharmacotherapeutics specifies drug use, aligning with the definition and clinical practice.
Question 3 of 5
In Fried's rule of dosage calculation, it is the number of months a child has reached an age when an adult dose can be tolerated>
Correct Answer: C
Rationale: In Fried's rule for dosage calculation, the formula is to divide the child's age in months by 150 to find the fraction of adult dose that can be tolerated. Generally, a child is considered to tolerate an adult dose when they have reached 12 months of age. This is based on the assumption that a 12-month-old child can typically tolerate a dose similar to that of an adult.
Therefore, the correct answer is 12 months, which is option C.
Question 4 of 5
The 8-year-old patient is receiving methylphenidate (Ritalin). The patient's mother tells the nurse that he won't eat while on his medication. What is the best response by the nurse?
Correct Answer: B
Rationale: Methylphenidate curbs appetite-giving it post-meals and adding snacks offsets weight loss, per practical management. Depression isn't indicated-appetite loss is a known effect. Appetite stimulants aren't standard. Nutritionists help long-term, not acutely. Post-meal dosing balances efficacy and nutrition, per care.
Question 5 of 5
A 27-year-old medical student has recurrent sinusitis and takes an over-the-counter agent. Unfortunately, he fell asleep while taking his final examination of the anatomy course. Which of the following agents is most likely to cause this adverse effect?
Correct Answer: D
Rationale: Sinusitis treatment often involves OTC antihistamines. Diphenhydramine , an H1 antihistamine, causes sedation, explaining the student's sleepiness during the exam. Doxycycline , an antibiotic, doesn't sedate. Doxylamine , another sedating antihistamine, is possible but less commonly linked to sinusitis OTC use. Doxazosin , an α-blocker, isn't for sinusitis. Hydroxyzine (E) sedates but is prescription-based. Diphenhydramine's widespread OTC availability and drowsiness side effect fit the scenario, impacting the student's performance.
