Question 1 of 5
When taking Nitroglycerine (transdermal), you should have how many hours nitrate free each day?
Correct Answer: C
Rationale: When taking Nitroglycerine (transdermal), it is recommended to have a nitrate-free interval of at least 10-12 hours to prevent tolerance from developing. Tolerance can occur if the medication is continuously delivered without a break, leading to reduced effectiveness. Therefore, having a nitrate-free interval of 3-4 hours each day helps to maintain the efficacy of Nitroglycerine therapy and prevent tolerance.
Question 2 of 5
Which of the following is NOT a site for drug metabolism:
Correct Answer: D
Rationale: The placenta is not a site for drug metabolism. Drug metabolism primarily occurs in the liver, gastrointestinal tract (GIT), skin, and kidney. The placenta serves as a barrier between the mother and fetus and is involved in nutrient and waste exchange but does not play a significant role in drug metabolism processes.
Question 3 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 4 of 5
What route is Amlodipine taken?
Correct Answer: A
Rationale: Amlodipine is a medication that is taken orally, usually in the form of tablets. The abbreviation "PO" stands for per os, which means by mouth or orally. Amlodipine is widely prescribed to treat high blood pressure and certain types of chest pain. It works by relaxing the blood vessels, making it easier for the heart to pump blood. Taking amlodipine orally allows it to be absorbed through the digestive system and enter the bloodstream to exert its therapeutic effects.
Question 5 of 5
A 28-year-old woman presents to the emergency department in an acute asthma exacerbation. Her asthma developed in her 20s after she had recurrent upper respiratory infections. She was doing well, but she twisted her ankle yesterday and was taking aspirin to reduce the inflammation. She is diagnosed with aspirin-induced asthma. What is the most appropriate long-term treatment for her condition?
Correct Answer: D
Rationale: Aspirin-induced asthma (AIA) involves leukotriene overproduction. Zafirlukast , a leukotriene receptor blocker-prevents attacks long-term. Albuterol and Ipratropium treat acutely. Cromolyn stabilizes mast cells but is less specific. Theophylline (E) is outdated. Zafirlukast targets AIA's pathophysiology.
