Which of the following types of cancer affects the colon and rectum the most?

Correct! Wrong!

Explanation:
Adenocarcinoma, which develops in the epithelial lining of the gut, accounts for the majority (about 95%) of cases of cancer of the colon and rectum. A precancerous polyp frequently gives rise to adenocarcinomas. Because colorectal cancers may not manifest symptoms until they are advanced and changes in bowel habits or rectal bleeding start to develop, early diagnosis through screening is crucial. If the tumor invades blood arteries, hemorrhage may happen, and blockage may happen as the mass grows.

Which of the following time frames should multi-use vials that have been accessed and used be thrown away within, unless otherwise specified by the manufacturer?

Correct! Wrong!

Explanation:
Multi-use vials should be thrown away within 28 days after being accessed and used unless the manufacturer specifies otherwise. Multi-use vials include preservatives but are susceptible to bacterial contamination and offer no virus protection. Multi-used vials should, whenever feasible, be kept for only one patient and kept away from the treatment area to avoid accidental contamination. Each time the vial is accessed, a new needle and syringe should be used.

A metoclopramide-using patient has been given a haloperidol prescription. Which of the following conditions does this medication combination put the patient at higher risk for?

Correct! Wrong!

Explanation:
Metoclopramide has been prescribed for a patient who is taking haloperidol; this medication combination increases the patient's risk of developing dyskinesia. The combination of the two medications increases their potential for causing uncontrollable movement abnormalities and increases the risk of neuroleptic malignant syndrome, a potentially fatal condition. Metoclopramide medication that lasts longer than 12 weeks increases the incidence of tardive dyskinesia. Numerous other medications, including phenothiazines and other antipsychotics, may also interact with metoclopramide.

The BVMGR (beliefs, values, meanings, goals, and relationships) rubric is being used by the nurse to implement spiritual care. These aspects apply to which of the following?

Correct! Wrong!

Explanation:
These elements relate to the patient evaluation if the nurse is utilizing the BVMGR (beliefs, values, meaning, goals, and relationships) rubric to provide spiritual care. To put it another way, the nurse should make an effort to comprehend the patient's BVMGR, refrain from interjecting personal BVMGR, and refrain from preaching if her BVMGR differs from the patient's. Even though the nurse may not share the patient's beliefs, she or he should always make an effort to comprehend and respect them.

For those who are lactose intolerant, which of the following dairy products is MOST LIKELY to have the least amount of lactose?

Correct! Wrong!

Explanation:
People who are lactose intolerant are more likely to tolerate Greek yogurt than other dairy products because it is thicker than conventional whole-fat yogurt, more of the whey is eliminated, and the lactose is part of the whey. Due to a lack of the enzyme required to digest lactose, those who are lactose intolerant experience stomach pain, gas, distention, and diarrhea after consuming dairy products. Now that some dairy products are lactose-free, Lactaid can be used to make up for the lost enzyme.

Which of the following should be done if the patient has a nose stud and an enclosed lip ring and is due for a colonoscopy?

Correct! Wrong!

Explanation:
A nose stud and an enclosed lip ring should both be removed from patients who are scheduled for colonoscopies before the surgery because they increase the risk of trauma and aspiration if they should become dislodged. Nose studs are removed by gently pressing down while pulling outward. Applying pressure within the ring to drive the ends apart will allow you to remove enclosed lip rings.

Which of the following is evaluated primarily using doppler ultrasound?

Correct! Wrong!

Explanation:
Doppler ultrasound is mostly used to evaluate blood flow (direction, speed). within the context of an abdominal ultrasound. Doppler ultrasound may be used to spot tumor-related alterations in blood flow as well as organs with poor organ circulation. Doppler imaging distinguishes between antegrade blood flow, which moves forward as expected, and retrograde blood flow, which moves backward as unexpected. Due to the diverse changes in blood flow caused by various processes, doppler imaging is frequently used to evaluate hepatic blood flow.
