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. A nurse is required to float to another unit within the hospital where he is asked to care for a client on a ventilator. The nurse is uncomfortable with this assignment, as he has not had a ventilated client since nursing school. What is the nurse's most appropriate response?

• A. Explain to the nursing supervisor the level of discomfort and ask for a different assignment
• B. State that the client's needs are outside the nurse's scope of practice and request a different assignment
• C. Accept the assignment, asking for help when necessary
• D. Request to return to the home unit and send another nurse who can perform the job

Correct answer: A

Rationale: When floating to another unit and asked to take an assignment that falls outside a nurse's comfort zone, the nurse should notify the area supervisor of the level of discomfort and request a different assignment. Caring for ventilated clients typically falls within the scope of nursing practice; however, discomfort with the situation may not necessarily be overcome by accepting the assignment. Alternatively, the effects could be harmful to the client if the nurse is unfamiliar with this type of care. Requesting a different assignment is the most appropriate response in this situation, ensuring patient safety and the nurse's comfort level. Stating that the client's needs are outside the nurse's scope of practice (Choice B) may not be accurate, as caring for ventilated clients usually falls within the scope of nursing practice. Accepting the assignment (Choice C) without addressing the discomfort may compromise patient safety. Requesting to return to the home unit (Choice D) does not address the immediate need of caring for the ventilated client and may delay appropriate care.

4. A nurse is caring for a 3-day old infant who needs an exchange transfusion. Which of the following statements is appropriate for teaching the child's parents about this procedure?

• A. The registered nurse will be performing the procedure
• B. The procedure takes approximately 1 ? hours.
• C. The nurse will draw out 250cc of blood and then immediately replace it with 250cc
• D. The infant will continue to receive phototherapy during the procedure.

Correct answer: B

Rationale: : An exchange transfusion is a method of controlling high bilirubin levels in infants when traditional phototherapy is unsuccessful. During an exchange transfusion, the physician removes 5-10 cc of blood and then replaces it with donor blood. The parents of this infant should know that the procedure is always performed by a physician and will take approximately 1 � hours to complete.

5. When teaching a client with coronary artery disease about nutrition, what should the nurse emphasize?

• A. Eating three balanced meals a day
• B. Adding complex carbohydrates
• C. Avoiding very heavy meals
• D. Limiting sodium intake to 7 g per day

Correct answer: C

Rationale: The correct answer is to emphasize avoiding very heavy meals. Eating large, heavy meals can divert blood away from the heart for digestion, potentially endangering clients with coronary artery disease. This practice may lead to an increased risk of plaque accumulation in the arteries, potentially obstructing the delivery of blood and oxygen to vital organs. Choices A, B, and D are incorrect. While eating three balanced meals a day, adding complex carbohydrates, and limiting sodium intake are generally good dietary practices, they are not the primary focus when teaching a client with coronary artery disease about nutrition. The emphasis should be on avoiding heavy meals that can strain the cardiovascular system.
