Question 1 of 5
Atropine:
Correct Answer: A
Rationale: Atropine, a muscarinic antagonist, causes bronchodilation by relaxing bronchial smooth muscle, a true statement used in asthma or COPD. It produces mydriasis (pupil dilation), not miosis (constriction), making that false, as it blocks parasympathetic tone. It's highly lipid-soluble, crossing the blood-brain barrier, so that's false. It doesn't block acetylcholine (ACh) reuptake (there's no such mechanism) but competitively inhibits muscarinic receptors, so that's incorrect. It reduces, not increases, salivary secretions. Bronchodilation is a primary therapeutic effect, reflecting atropine's anticholinergic action, critical for respiratory applications and distinguishing it from sympathomimetics.
Question 2 of 5
The nursing mother asks the nurse if it is all right to take St. John's wort for mild depression. What is the best response by the nurse?
Correct Answer: C
Rationale: St. John's wort, an herbal antidepressant, passes into breast milk, potentially affecting the baby-e.g., sedation or colic-making it unsafe without medical advice. Allergies lack evidence as a concern. Milk production isn't a known issue. Taste changes are unproven. Excretion risk is the primary concern, supported by pharmacokinetics, prioritizing infant safety.
Question 3 of 5
Which method would the nurse use to administer medications to school-age children?
Correct Answer: B
Rationale: School-age kids (6-12) grasp brief explanations-e.g., 'This helps your cough'-fitting their cognitive level, easing administration. Full decision-making exceeds maturity. Holding down distresses, not needed. Lengthy talks lose attention. Brief explanation leverages development, ensuring cooperation.
Question 4 of 5
The client receives hydroxychloroquine sulfate (Plaquenil). Which test does the nurse tell the client should be done on a regular basis?
Correct Answer: B
Rationale: The correct answer is B) Eye exams. Hydroxychloroquine sulfate (Plaquenil) is known to have potential adverse effects on the eyes, particularly the retina, which can lead to serious vision problems. Therefore, regular eye exams are crucial to monitor for any signs of retinal damage and ensure early detection and intervention if necessary. Option A) Serum potassium is not directly related to the use of hydroxychloroquine sulfate. While electrolyte imbalances can be a concern with some medications, it is not a specific monitoring requirement for this drug. Option C) Serum glucose is also not specifically associated with hydroxychloroquine sulfate use. Monitoring blood glucose levels is more relevant for medications that can affect blood sugar levels, such as certain diabetes medications. Option D) Blood pressure is not the primary focus of monitoring for a client taking hydroxychloroquine sulfate. While monitoring blood pressure is important for overall health, it is not the most critical assessment related to this medication. In an educational context, it is essential for nurses to understand the specific monitoring requirements for medications to ensure patient safety and optimal outcomes. By emphasizing the importance of regular eye exams for clients on hydroxychloroquine sulfate, nurses can help prevent or minimize potential vision-related complications and provide comprehensive care for their patients.
Question 5 of 5
A 63-year-old woman with a history of cardiac arrhythmia maintained on quinidine presents to her primary care physician complaining of frequency, urgency, and dysuria. Urine culture reveals >100,000 CFU/mL of Escherichia coli. She is given a prescription for ciprofloxacin 500 mg to be taken twice daily for 7 days. Which of the following sequelae could be problematic for this patient?
Correct Answer: D
Rationale: Quinidine and ciprofloxacin both prolong the QT interval, risking torsades de pointes. Option , QT prolongation, is correct-combined use heightens arrhythmia risk in this patient. Asystole , MI , pulmonary edema , and embolism (E) aren't directly linked. This drug interaction demands monitoring, critical given her cardiac history.
