Nursing Elites

1. One drug can alter the absorption of another drug. One drug increases intestinal motility. Which effect does this have on the second drug?

• A. None; absorption of the second drug is not affected.
• B. The increased gut motility decreases the absorption of the second drug.
• C. The absorption of the second drug cannot be predicted.
• D. Less of the second drug is absorbed.

Correct answer: D

Rationale: When one drug increases intestinal motility, it accelerates the movement of the second drug through the system. Since most oral medications are absorbed in the intestine, the faster transit time decreases the absorption of the second drug. Therefore, less of the second drug is absorbed. Choice A is incorrect because the increased gut motility does affect the absorption of the second drug. Choice C is incorrect as the effect of increased intestinal motility on drug absorption can be predicted based on pharmacokinetic principles. Choice B is incorrect as increased gut motility would not increase but decrease the absorption of the second drug.

2. In alcoholics with anemia:

• A. Pernicious anemia is more common than folic acid deficiency.
• B. Iron deficiency and folic acid deficiency can coexist.
• C. The alcohol interferes with iron absorption.
• D. Oral vitamin replacement is contraindicated.

Correct answer: B

Rationale: In alcoholics with anemia, iron deficiency and folic acid deficiency can coexist due to poor dietary intake and malabsorption issues associated with chronic alcohol consumption. Pernicious anemia, primarily related to vitamin B12 deficiency, is not commonly seen in alcoholics. While alcohol can interfere with iron absorption, it is not the sole factor contributing to anemia in alcoholics. Oral vitamin replacement is not contraindicated in alcoholics with anemia; however, it may be less effective due to absorption issues related to alcohol consumption.

3. A client asks a nurse working in a dental office what type of drug the dentist uses to provide anesthesia during the extraction of the client's wisdom teeth. The dentist uses an anesthetic gas, also known as laughing gas. This agent is:

• A. nitrous oxide.
• B. nitrogen.
• C. nitric oxide.
• D. nitrogen dioxide.

Correct answer: A

Rationale: The correct answer is nitrous oxide. Nitrous oxide is commonly known as laughing gas and is used as an anesthetic gas for procedures like dental extractions. It produces analgesia and mild euphoria without loss of consciousness. Nitrogen is a nonmetallic element found in air, while nitric oxide is a vasodilator produced from L-arginine. Nitrogen dioxide is a poisonous gas found in smog and exhaust fumes and is not used for anesthesia.

4. After an escharotomy of the forearm, what is the priority nursing assessment for the client who has returned to your unit?

• A. Infection
• B. Incision
• C. Pain
• D. Tissue perfusion

Correct answer: D

Rationale: The correct answer is "Tissue perfusion." After an escharotomy, the priority assessment is to ensure adequate tissue perfusion to the affected limb. Escharotomy is performed to relieve circulatory compromise by cutting through the eschar, so monitoring tissue perfusion is crucial to assess the effectiveness of the procedure and prevent complications. Assessing for infection is important but comes after ensuring adequate tissue perfusion. Checking the incision is necessary but assessing tissue perfusion takes precedence. Pain assessment is important but not the priority compared to assessing tissue perfusion to prevent ischemic complications.

5. Which of the following is likely to increase the risk of sexually transmitted disease?

• A. alcohol use
• B. certain types of sexual practices
• C. oral contraception use
• D. all of the above

Correct answer: D

Rationale: All of the above factors are likely to increase the risk of sexually transmitted diseases (STDs). Alcohol use can impair judgment, leading to risky sexual behavior. Certain types of sexual practices, especially unprotected sex or multiple partners, increase the likelihood of contracting STDs. While oral contraception use does not directly increase the risk of STDs, it does not protect against them either. Therefore, all the choices (alcohol use, certain types of sexual practices, and oral contraception use) can contribute to an increased risk of contracting STDs.
