Correct Answer is C
Explanation
A. Lithium is not considered addictive in the traditional sense, and it does not need to be discontinued after six months unless clinically indicated.
B. Diuretics are generally avoided in patients taking lithium due to the risk of lithium toxicity from altered renal clearance, rather than being a routine prescription for difficulty urinating.
C. Close monitoring of lithium levels is crucial to avoid toxicity and ensure therapeutic efficacy, making this statement correct and essential for the patient’s education.
D. While weight gain can occur with lithium therapy, it is not an indicator of lithium toxicity; symptoms of toxicity include nausea, tremors, and confusion rather than weight gain.
Correct Answer is B
Explanation
A. A high first-pass effect means that a significant amount of the drug is metabolized by the liver before reaching systemic circulation, making oral administration less effective.
B. Morphine with a high first-pass effect will be more effective when administered via non-enteral routes, such as IV or subcutaneous, to bypass the liver's initial metabolism.
C. The first-pass effect does not influence the kidney’s rate of excretion but rather the liver’s initial metabolism of the drug.
D. The liver, not the kidneys, is responsible for the first-pass metabolism, which occurs before the drug reaches systemic circulation when taken orally.
