Nursing Elites

1. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?

• A. serotonin
• B. cortisol
• C. alcohol
• D. narcotics

Correct answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

2. An LPN is caring for a primarily bedridden client. Which finding should be of least concern?

• A. swollen feet
• B. brown discoloration above the ankles
• C. leg pain
• D. capillary refill time of 3 seconds on the big toe

Correct answer: D

Rationale: The correct answer is the capillary refill time of 3 seconds on the big toe. A capillary refill time longer than three seconds may indicate inadequate blood flow. Swollen feet, brown discoloration above the ankles, and leg pain are all signs of venous insufficiency to the lower extremities. These findings can suggest circulation issues and require further assessment and intervention. Therefore, they should be of more concern compared to the capillary refill time of 3 seconds on the big toe, which is within the normal range of 2-3 seconds.

3. When a 17-year-old client arrives at the clinic suspecting a sexually transmitted infection, what information does the nurse provide concerning informed consent?

• A. She will need to sign an informed consent form.
• B. Her mother or father will need to be contacted for permission to treat her.
• C. A consent form is not needed if the problem is a sexually transmitted infection.
• D. Anyone over the age of 18 years may sign a consent form for her treatment.

Correct answer: A

Rationale: Informed consent is a person's agreement to allow something, such as a treatment, to be performed. A consent form is required even if the problem is a sexually transmitted infection. If the client is a minor, the minor may sign the informed consent form in specific situations, including seeking treatment for a sexually transmitted infection. In this case, the 17-year-old client is seeking examination and treatment for a sexually transmitted infection, so she will need to sign the informed consent form. Contacting her parents for permission is not required in this situation. Choice C is incorrect because a consent form is necessary regardless of the medical issue. Choice D is incorrect because the individual's age is not the determining factor; rather, it is the nature of the medical service being sought that dictates the need for informed consent.

4. Which of the following ethnic groups is at highest risk in the United States for pesticide-related injuries?

• A. Native American
• B. Asian-Pacific
• C. Norwegian
• D. Hispanic

Correct answer: D

Rationale: The correct answer is 'Hispanic.' Hispanic individuals in the United States are at a higher risk for pesticide-related injuries due to their representation among migrant workers in agricultural settings. This exposure to pesticides in their work environments increases their risk compared to other ethnic groups. Choice A, 'Native American,' although indigenous populations may face environmental health disparities, the higher risk in this context is among Hispanic individuals. Choice B, 'Asian-Pacific,' and Choice C, 'Norwegian,' do not have the same level of exposure to pesticides as Hispanic migrant workers, making them less susceptible to pesticide-related injuries.

5. What condition is mammography used to detect?

• A. pain
• B. tumor
• C. edema
• D. epilepsy

Correct answer: B

Rationale: Mammography is specifically used to detect tumors or abnormal growths, especially in breast tissue. It is not a tool for identifying pain, edema, or epilepsy. Therefore, the correct answer is 'tumor.' Pain is a symptom, edema is swelling, and epilepsy is a neurological disorder; none of these are conditions typically detected through mammography.
