A patient is ordered a phenothiazine antiemetic for treatment of nausea and vomiting associated with chemotherapy. The nurse will be evaluating for a positive effect. At what time should the nurse administer the drug?
as requested by the patient.
1 hour after chemotherapy administration.
The night before the treatment, the day of the treatment, and for 24 hours after the treatment.
the day of treatment.
The Correct Answer is C
A. As requested by the patient.
Administering the drug only when requested by the patient may not provide adequate prophylaxis against chemotherapy-induced nausea and vomiting. These medications are often prescribed on a schedule to prevent symptoms rather than treating them reactively.
B. 1 hour after chemotherapy administration.
Waiting until 1 hour after chemotherapy administration may not cover the full period during which nausea and vomiting are likely to occur. The administration schedule for antiemetics is often more extended to provide better coverage.
C. The night before the treatment, the day of the treatment, and for 24 hours after the treatment.
This is the correct choice. Administering phenothiazine antiemetics according to this schedule helps ensure continuous coverage during the critical period when chemotherapy-induced nausea and vomiting are most likely to occur.
D. The day of treatment.
Administering the drug only on the day of treatment may not provide sufficient coverage for the entire duration when chemotherapy-induced nausea and vomiting can occur. Again, the schedule mentioned in option C is more comprehensive for prevention.

Correct Answer is A
Explanation
A. Aspirin and warfarin
The combination of aspirin and warfarin poses a potential risk of increased bleeding and bruising. Both aspirin and warfarin are anticoagulants, and when used together, they can potentiate each other's effects, leading to a higher risk of bleeding events, including easy bruising.
B. Sulfasalazine and acetaminophen
Sulfasalazine is often used in the treatment of arthritis and inflammatory bowel disease, while acetaminophen is a commonly used pain reliever. There is no significant interaction between these two medications leading to increased bleeding or bruising.
C. Tolmetin and propranolol
Tolmetin is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief, and propranolol is a beta-blocker used for conditions such as hypertension. While both medications have their own potential side effects, there is no specific interaction between them that significantly increases the risk of bleeding or bruising.
D. Meloxicam and amlodipine
Meloxicam is an NSAID, and amlodipine is a calcium channel blocker used for hypertension. Similar to option C, there is no known significant interaction between these two medications that would lead to increased bleeding or bruising.
Correct Answer is B
Explanation
A. Give the child fluids and proceed to the emergency department.
While giving the child fluids is generally important, proceeding to the emergency department without consulting poison control may not be the most appropriate initial action. Poison control can provide specific guidance based on the substance ingested.
B. Call the poison control center and follow directions.
The safest advice for a toddler who has ingested a small amount of household cleaning fluid is to call the poison control center and follow their directions. Poison control centers are staffed with professionals who can provide specific guidance based on the type and amount of the ingested substance. They can advise on the appropriate steps to take, such as whether immediate medical attention is needed or if monitoring at home is sufficient.
C. Administer syrup of ipecac and monitor for vomiting.
The use of syrup of ipecac is no longer recommended as a routine measure for ingested substances. It can have adverse effects and may not be effective for all substances. Consulting poison control for guidance is considered a more appropriate approach.
D. Have the toddler eat bread to absorb the substance.
The ingestion of certain substances may not be effectively addressed by having the toddler eat bread. The specific advice for management should come from poison control, which can provide evidence-based guidance.
