Nursing Elites

1. The client asked about the role of leptin in the body. Which response should the nurse provide?

• A. It increases food intake in clients, thereby promoting obesity.
• B. It assists in the regulation of steroids.
• C. It increases the total fat mass of people who are obese.
• D. It might decrease the total fat mass in the bodies of people who are obese.

Correct answer: D

Rationale: Leptin is a protein hormone expressed in fat cells that regulates fat cell percentage in the body. It is associated with increased energy expenditure and decreased food intake through hypothalamic control. In obese individuals, there may be insensitivity or resistance to leptin's effects. Leptin influences other hormones like insulin and genetic factors related to fat regulation. Therefore, the correct response is that leptin might decrease total fat mass in obese individuals as it is involved in energy balance and fat regulation. Choices A, B, and C are incorrect because leptin does not increase food intake or promote obesity; it does not assist in the regulation of steroids, and it does not increase total fat mass in people who are obese.

2. The nurse is caring for a client who is 28 weeks pregnant and complains of swollen hands and feet. Which symptom below would cause the greatest concern?

• A. Nasal congestion
• B. Hiccups
• C. Blood glucose of 150
• D. Muscle spasms

Correct answer: D

Rationale: The correct answer is muscle spasms because they can be indicative of a severe condition like preeclampsia, which is a serious complication during pregnancy characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys. Nasal congestion and hiccups are common discomforts during pregnancy and do not pose a severe risk to the client or fetus. A blood glucose level of 150, while slightly elevated, may not be alarming in a pregnant individual and can be managed through dietary modifications or medication adjustments. Muscle spasms, especially in the context of pregnancy, should be taken seriously and thoroughly assessed to rule out any underlying serious conditions.

3. What is one characteristic of human immunodeficiency virus (HIV)?

• A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
• B. HIV replication occurs intracellularly.
• C. HIV integrates its genetic material into the host cell's DNA.
• D. DNA replication is irrelevant to HIV.

Correct answer: C

Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.

4. A client with sleep apnea has been ordered a CPAP machine. Which action could the RN delegate to a nursing assistant?

• A. Reminding the client to apply the CPAP at bedtime
• B. Obtaining every three-hour oxygen saturation levels
• C. Teaching the client how to turn on the CPAP machine
• D. Assessing for fatigue or depression caused by poor sleep

Correct answer: A

Rationale: The correct answer is reminding the client to apply the CPAP at bedtime. This task can be safely delegated to a nursing assistant as it involves a simple and routine reminder. Option B, obtaining oxygen saturation levels, requires a higher level of training and interpretation of results, making it more appropriate for an RN. Option C, teaching the client how to turn on the CPAP machine, involves educating the client and ensuring proper use of medical equipment, which is within the RN's scope of practice. Option D, assessing for fatigue or depression, requires a comprehensive evaluation that involves interpreting symptoms and identifying underlying causes, making it more suitable for an RN to address.

5. What skin color does a client with jaundice have?

• A. pale
• B. ruddy
• C. yellow
• D. pink

Correct answer: C

Rationale: The correct answer is C: yellow. Jaundice is a condition characterized by yellowing of the skin due to increased levels of bilirubin in the blood. This excess bilirubin causes the skin and whites of the eyes to appear yellow. Choice A, pale, is not typically associated with jaundice. Choice B, ruddy, describes a reddish skin color and is not indicative of jaundice. Choice D, pink, is a normal skin color and not a symptom of jaundice.
