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. 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.

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. Which of the following is an example of a living will?

• A. A client's son has been appointed to make his healthcare decisions if he becomes incapacitated
• B. A client has designated which of his children will receive his home and property before he dies
• C. A client has instructions that he does not want to be resuscitated through chest compressions if his heart stops beating
• D. A client designates what type of burial or cremation services he would want after his death

Correct answer: C

Rationale: A living will is a type of advanced directive that a client develops to stipulate his preferences for healthcare in the event that he is unable to do so. This includes specific instructions about medical treatments in certain situations. Choice C is the correct answer as it reflects a scenario where the client has clearly outlined their preference regarding resuscitation through chest compressions. Choices A, B, and D do not pertain to a living will. Choice A involves a healthcare proxy or agent, choice B involves a will or estate planning, and choice D involves funeral or burial arrangements, which are not part of a living will.

5. What action by the nurse will be most effective in decreasing the spread of pertussis in a community setting?

• A. Providing supportive care to patients diagnosed with pertussis
• B. Teaching family members about the importance of careful handwashing
• C. Teaching patients about the necessity of adult pertussis immunizations
• D. Encouraging patients to complete the prescribed course of antibiotics

Correct answer: C

Rationale: The most effective action by the nurse to decrease the spread of pertussis in a community setting is to teach patients about the necessity of adult pertussis immunizations. The increased rate of pertussis in adults is often attributed to waning immunity after childhood immunization. Immunization is highly effective in protecting communities from infectious diseases. While teaching about handwashing is important for overall infection control, pertussis is primarily spread through respiratory droplets and contact with secretions. Providing supportive care does not significantly impact the disease course or transmission risk. Encouraging completion of antibiotics may help reduce transmission, but patients likely have already spread the disease by the time the diagnosis is made. Therefore, the emphasis should be on prevention through immunization to reduce the spread of pertussis.
