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

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. Albert is a patient in the hospital who is scheduled for surgery the following morning. After the pre-operative visit from the anesthesia staff member who has obtained surgical consent, Albert asks for an explanation of what type of surgery he is going to have. He states that he's not sure what he just signed. What is your best response?

Correct answer: C

Rationale: The correct response is to ensure that the patient fully understands the nature of the surgery they are about to undergo. If the patient expresses uncertainty about the procedure they signed consent for, it indicates a lack of informed consent, which is essential before any surgery. By requesting the nurse anesthetist to return and provide a more detailed explanation, the patient can make an informed decision. Choices A, B, and D do not address the issue of the patient's lack of understanding and the need for informed consent, making them incorrect. Option C is the best course of action to rectify the situation and ensure the patient's understanding and consent are properly obtained.

3. When a mother is inquiring about her child's ability to potty train, what is the most critical aspect of toilet training?

Correct answer: C

Rationale: The most critical aspect of toilet training is the overall mental and physical abilities of the child. While age can play a role, it is not the sole determining factor. Understanding instructions is important but may not be the most critical aspect. Consistent attempts with positive reinforcement can be helpful, but without considering the child's abilities, it may not lead to successful potty training.

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

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.

5. A client has a right-sided chest tube with 50 cc of serosanguinous fluid in the collection chamber and air bubbles are collecting in the water seal chamber. What is the most appropriate action for the nurse to take at this time?

Correct answer: C

Rationale: The water seal of a chest tube acts as a one-way valve. Air bubbles in the water seal indicate a leak between the client and the chamber. The nurse should briefly clamp the tube near the client's chest to locate the source of the leak. Once identified, the nurse should unclamp the tubing and notify the physician immediately. Choice A is incorrect because air bubbles in the water seal chamber are not a normal finding and indicate a leak. Choice B is incorrect as stripping the tubing could aggravate the issue and is not the initial appropriate action. Choice D is incorrect as it does not address the immediate need to locate and address the leak.
