Grapefruit juice
Green tea
Vitamin C
Calcium supplements
The Correct Answer is A
Correct answer: a) Grapefruit juice
Rationale: Grapefruit juice can increase the blood levels of alprazolam and other benzodiazepines by inhibiting their metabolism in the liver. This can result in increased sedation, drowsiness, and risk of adverse effects.
Incorrect choices:
b) Green tea: Green tea does not interact with alprazolam or other benzodiazepines.
c) Vitamin C: Vitamin C does not interact with alprazolam or other benzodiazepines.

Correct Answer is A
Explanation
Correct answer: a) Ibuprofen (Advil)
Rationale: Ibuprofen and other nonsteroidal anti-inflammatory drugs (NSAIDs) can increase the blood levels of lithium by reducing its renal excretion. This can result in lithium toxicity, which can cause nausea, vomiting, tremors, confusion, and seizures.
Incorrect choices:
b) Levothyroxine (Synthroid): Levothyroxine and other thyroid hormones do not interact with lithium.
c) Omeprazole (Prilosec): Omeprazole and other proton pump inhibitors (PPIs) do not interact with lithium.
d) Metformin (Glucophage): Metformin and other antidiabetic drugs do not interact with lithium.
Correct Answer is B
Explanation
Correct answer: b) Drowsiness and respiratory depression
Rationale: Drowsiness and respiratory depression are signs of opioid overdose and indicate that the client is taking more than the prescribed dose or combining oxycodone with other depressants. The nurse should monitor the client's vital signs, administer naloxone if indicated, and report the situation to the prescriber.
Incorrect choices:
a) Constipation and dry mouth: These are common side effects of opioids and do not necessarily indicate abuse.
c) Nausea and vomiting: These are also common side effects of opioids and can be managed with antiemetics.
d) Pupillary constriction and itching: These are also common side effects of opioids and do not necessarily indicate abuse.
