Extract:
Question 1 of 5
The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?
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.
Question 2 of 5
What condition is mammography used to detect?
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.
Question 3 of 5
A client who is immobilized secondary to traction is complaining of constipation. Which of the following medications should the nurse expect to be ordered?
Correct Answer: D
Rationale: Colace is a stool softener that acts by pulling more water into the bowel lumen, making the stool soft and easier to evacuate. In the given scenario of constipation in an immobilized client, a stool softener like Colace is the appropriate choice to help facilitate bowel movements. Advil and Anasaid are nonsteroidal anti-inflammatory drugs (NSAIDs) used for pain relief, not for constipation. Clinocil is not a recognized medication for constipation relief.
Question 4 of 5
Which of the following lab values is associated with a decreased risk of cardiovascular disease?
Correct Answer: B
Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (
Choice
B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (
Choice
C) and low triglycerides (
Choice
D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.
Question 5 of 5
When a 17-year-old client arrives at the clinic suspecting a sexually transmitted infection, what information does the nurse provide concerning informed consent?
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.
