Nursing Elites

1. Which of the following indicates a hazard for a client on oxygen therapy?

• A. A 'No Smoking' sign is on the door.
• B. The client is wearing a synthetic gown.
• C. Electrical equipment is grounded.
• D. Matches are removed.

Correct answer: B

Rationale: The correct answer is that the client is wearing a synthetic gown. A synthetic gown might generate sparks of static electricity, which can be a fire hazard, especially in the presence of oxygen. Clients on oxygen therapy should wear cotton gowns to minimize the risk of fire. The other options are not hazards for a client on oxygen therapy: having a 'No Smoking' sign on the door promotes safety by preventing smoking, ensuring electrical equipment is grounded reduces the risk of electrical hazards, and removing matches decreases the risk of fire hazards.

2. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: A

Rationale: The correct answer is high HDL cholesterol. High HDL cholesterol levels are associated with a decreased risk of cardiovascular disease because HDL helps remove LDL cholesterol from the arteries, reducing plaque buildup. Low HDL cholesterol (choice B) is actually associated with an increased risk of cardiovascular disease. Low total cholesterol (choice C) or low triglycerides (choice D) are not indicators of a decreased risk of cardiovascular disease; in fact, extremely low total cholesterol levels may indicate other health issues.

3. What sign might the nurse observe in a client with a high ammonia level?

• A. coma
• B. edema
• C. hypoxia
• D. polyuria

Correct answer: A

Rationale: Coma is a sign that a nurse might observe in a client with a high ammonia level. Elevated ammonia levels can lead to hepatic encephalopathy, a condition characterized by impaired brain function, which can progress to coma. Edema (choice B) is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia (choice C) is a condition of inadequate oxygen supply to tissues and is not directly related to high ammonia levels. Polyuria (choice D) refers to excessive urination and is not a typical sign of high ammonia levels.

4. A client asks a nurse about the procedure for becoming an organ donor. The nurse provides the client with which information?

• A. To speak with the chaplain about the psychosocial aspects of becoming a donor
• B. That this decision must be made by the next of kin at the time of the client's death
• C. That anatomic gifts must be made in writing and signed by the client
• D. To let the health care provider know about the request so that it may be documented in the client's record

Correct answer: C

Rationale: When a person wishes to become an organ donor, they need to understand that anatomic gifts must be made in writing and signed by the individual. The gift must be made by the donor themselves, typically an individual who is at least 18 years old. If the client is unable to sign, the document should be signed by another person and two witnesses. While speaking to a chaplain or informing the healthcare provider may be part of the process, the essential step is to have a written document signed by the client. Choice A is incorrect as it does not address the procedural aspect of becoming an organ donor. Choice B is incorrect as the decision to make an anatomic gift is typically made by the individual themselves, not the next of kin. Choice D is incorrect as simply informing the healthcare provider is not sufficient for the procedure of becoming an organ donor; a written and signed document by the client is necessary.

5. What is the 24-hour day-night cycle known as?

• A. circadian rhythm
• B. infradian rhythm
• C. ultradian rhythm
• D. non-REM rhythm

Correct answer: A

Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.
