A nurse is reviewing the list of current medications for a client who is to start a new prescription for carbamazepine. The nurse should identify which of the following medications interacts with carbamazepine.
Estrogen-progestin combination
Nicotine transdermal system
Diphenhydramine
Beclomethasone
The Correct Answer is A
A. Estrogen-progestin combination:
Correct Answer: This medication interacts with carbamazepine.
Explanation: Carbamazepine is known to induce certain liver enzymes, including cytochrome P450 enzymes. These enzymes play a role in the metabolism of various medications, including estrogen-containing oral contraceptives (estrogen-progestin combinations). Carbamazepine can increase the metabolism of estrogen-progestin combinations, potentially reducing their effectiveness and increasing the risk of contraceptive failure. Therefore, this interaction can lead to decreased contraceptive efficacy and the potential for unintended pregnancy.
B. Nicotine transdermal system:
Incorrect Explanation: This medication does not interact with carbamazepine.
Explanation: Nicotine replacement therapies, such as nicotine transdermal systems, are not known to have significant interactions with carbamazepine. These therapies are primarily used to aid in smoking cessation and do not share metabolic pathways with carbamazepine.
C. Diphenhydramine:
Incorrect Explanation: This medication does not interact with carbamazepine.
Explanation: Diphenhydramine is an antihistamine used for allergies and as a sleep aid. It does not have a well-established interaction with carbamazepine. However, it's important to note that carbamazepine can have central nervous system (CNS) effects, so caution should be exercised when combining it with other medications that also have CNS effects.
D. Beclomethasone:
Incorrect Explanation: This medication does not interact with carbamazepine.
Explanation: Beclomethasone is a corticosteroid used to manage inflammation associated with conditions like asthma and allergic rhinitis. It is not known to interact with carbamazepine. These two medications have different mechanisms of action and do not share significant metabolic pathways.

Correct Answer is D
Explanation
A. "I should stay upright for at least 15 minutes after taking this medication.": This advice is usually given with medications like bisphosphonates to prevent esophageal irritation. It is not necessary for ferrous gluconate.
B. "I should take this medication with 8 ounces of milk.": Iron supplements should not be taken with milk or other dairy products because they can interfere with iron absorption.
C. "I should take an antacid with this medication to prevent stomach upset.": Antacids can also interfere with iron absorption and should be taken separately from iron supplements.
D. "I should notify my provider if my stools turn black."
Ferrous gluconate is an iron supplement used to treat iron deficiency anemia. One common side effect of iron supplementation is the darkening of stools, often to a black color. This is not harmful but is important for the client to be aware of. It is due to the reaction of iron with the acids and enzymes in the gastrointestinal tract.
Correct Answer is A
Explanation
A. Drowsiness:
Correct Answer: This adverse effect is important for the client to monitor for when taking paroxetine.
Explanation: Paroxetine is an antidepressant medication classified as a selective serotonin reuptake inhibitor (SSRI). Drowsiness or sedation can be a common side effect of paroxetine and other SSRIs. The client should be advised to monitor their response to the medication and report excessive drowsiness to their healthcare provider.
B. Peripheral edema:
Incorrect Explanation: Peripheral edema is not a typical adverse effect of paroxetine.
Explanation: Peripheral edema is not a common side effect associated with paroxetine use. It's important to monitor for adverse effects, but this specific symptom is not usually associated with this medication.
C. Tinnitus:
Incorrect Explanation: Tinnitus (ringing in the ears) is not commonly associated with paroxetine use.
Explanation: Tinnitus is not a typical side effect of paroxetine. It's important for the client to report any new or unusual symptoms, but tinnitus is not one of the more common adverse effects of this medication.
D. Alopecia:
Incorrect Explanation: Alopecia (hair loss) is not commonly associated with paroxetine use.
Explanation: Alopecia is not a typical side effect of paroxetine. While hair loss can occur with certain medications, it is not a common concern with paroxetine.
