Question 1 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 2 of 5
A patient who has been diagnosed with social anxiety disorder will begin taking venlafaxine(Effexor). The nurse who performs a medication and dietary history will be concerned about ingestion of which substance or drug?
Correct Answer: D
Rationale: St. John's wort is an herbal supplement that can interact with many medications, including venlafaxine (Effexor). When taken together, it can decrease the effectiveness of venlafaxine by increasing its metabolism, potentially leading to reduced therapeutic effects. This interaction can also increase the risk of side effects or adverse reactions. Therefore, the nurse should be concerned about the ingestion of St. John's wort when a patient is taking venlafaxine to ensure proper medication management and effectiveness. It is important for patients to inform healthcare providers about all supplements they are taking to prevent harmful interactions.
Question 3 of 5
The primary function of luteinizing hormone (LH) in men is to
Correct Answer: D
Rationale: Luteinizing hormone (LH), from the pituitary, stimulates Leydig cells in the testes to produce testosterone, the primary male sex hormone, making its regulation LH's chief role in men. Sperm production is driven by follicle-stimulating hormone (FSH), not LH, though both support fertility. Secondary sex characteristics, like body hair, depend on testosterone, which LH indirectly influences by controlling its synthesis, not directly regulating the traits. Growth of male sex organs relies on androgens, again tied to testosterone, not LH's direct action. Testosterone regulation is LH's specific function, as it triggers the steroidogenesis pathway, critical for male physiology, distinguishing it from FSH's gamete focus and underscoring its hormonal primacy in this context.
Question 4 of 5
The nurse notes in the patient™s medication orders that the patient will be starting anticoagulant therapy. What is the primary goal of anticoagulant therapy?
Correct Answer: C
Rationale: The primary goal of anticoagulant therapy is to prevent the formation of blood clots or thrombi. Anticoagulants work by inhibiting the clotting process in the blood, thereby reducing the risk of clot formation in the blood vessels. This helps to prevent conditions such as deep vein thrombosis, pulmonary embolism, stroke, and other thromboembolic events. Anticoagulants do not dissolve existing clots (thrombus), they work to prevent new clots from forming. So, the main objective of starting anticoagulant therapy in a patient is to prevent the development of thrombi.
Question 5 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.
