Nursing Elites

1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. Mrs. O is seen for follow-up after an episode of acute pancreatitis. Her physician orders a serum amylase level and the result is 200 U/L. Which of the following is a potential cause of this result?

• A. The client is pregnant
• B. The client has hypertension
• C. The client is in renal failure
• D. The client has pancreatitis

Correct answer: D

Rationale: An elevated serum amylase level after pancreatitis may indicate another attack of the condition. It is common to order serum amylase as part of routine follow-up after pancreatitis. Elevated levels can also be seen in related gastrointestinal conditions like cholecystitis or an intestinal blockage. Therefore, in this case, the most likely cause of the elevated serum amylase level is a recurrence or ongoing pancreatitis. The other options, including pregnancy, hypertension, and renal failure, are not typically associated with an elevated serum amylase level in the context of follow-up after acute pancreatitis.

3. Mrs. M has had diabetes for seven years. She has worked hard to control her blood glucose levels and watch her dietary intake. Her physician orders a hemoglobin A1C test. Which of the following best describes the action of this test?

• A. The test determines if the client is anemic and needs iron supplements
• B. The test determines if there is excess glucose building up in the urine
• C. The test determines the amount of hemoglobin reaching the liver to support gluconeogenesis
• D. The test determines the amount of hemoglobin that is coated with glucose

Correct answer: D

Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.

4. A nurse is assigned to care for a deaf client. During her lunch hour, she visits the hospital library and reads more about deaf culture in order to better provide appropriate care for her client. This action is an example of:

• A. Cultural knowledge
• B. Cultural noise
• C. Cultural diversity
• D. Cultural divide

Correct answer: A

Rationale: Cultural knowledge involves seeking information and educating oneself about different cultural groups. In this scenario, the nurse is demonstrating cultural knowledge by learning more about deaf culture to improve the care provided to the deaf client. This proactive approach helps in understanding the client's background, beliefs, and communication preferences, leading to better outcomes. 'Cultural noise' and 'Cultural divide' are incorrect as they do not reflect the nurse's positive action of seeking knowledge to enhance care. 'Cultural diversity' is also incorrect as it does not accurately describe the nurse's specific action of acquiring knowledge about a particular culture.

5. What would a healthcare professional expect to observe while assessing the growth of children during their school-age years?

• A. Decreasing amounts of body fat and muscle mass
• B. Little change in body appearance from year to year
• C. Progressive height increase of 4 inches each year
• D. Yearly weight gain of about 5.5 pounds per year

Correct answer: D

Rationale: During school-age years, children typically gain about 5.5 pounds per year and increase in height by about 2 inches annually. This steady growth pattern is expected between ages 2 to 10 years. Choice A is incorrect as children at this stage are expected to gain weight and grow in height. Choice B is incorrect as there should be noticeable changes in body appearance due to growth. Choice C is incorrect as a progressive height increase of 4 inches each year is not typical during the school-age years.
