Which of the following cell types is primarily responsible for the production of antibodies during the humoral immune response?
- A. Plasma cells
- B. T helper cells (Th cells)
- C. Memory B cells
- D. Macrophages
Correct Answer: A
Rationale: Plasma cells are the primary type of cells responsible for the production of antibodies during the humoral immune response. When activated by antigens, B cells differentiate into plasma cells, which are specialized in producing large quantities of antibodies. These antibodies are essential in fighting off infections by binding to antigens and marking them for destruction by other immune cells. T helper cells assist in activating B cells, but the actual production of antibodies is mainly carried out by plasma cells. Memory B cells are involved in mounting a rapid and specific secondary response upon re-exposure to the same antigen. Macrophages play a role in phagocytosis and antigen presentation, but they are not the primary cells responsible for producing antibodies during the humoral immune response.

Which of the following gives cues to the nurse that the patient may be grieving for loss?
- A. Thoughts, feelings , behavior, and physiologic complaints
- B. Hallucination, panic 1evel of anxiety, sense of impending doom
- C. Sad affect, anger anxiety, and sudden change of mood

Rationale: A grieving individual may show a range of cues across different aspects of their life. Thoughts may include constant preoccupation with the loss, difficulties in concentrating, or intrusive thoughts. Feelings may involve sadness, anger, guilt, confusion, or relief. Behavioral cues may include changes in sleep patterns, appetite, energy levels, social withdrawal, or the use of substances. Physiologic complaints can manifest as headaches, stomach issues, fatigue, or other physical symptoms. Therefore, when a nurse observes cues related to thoughts, feelings, behavior, and physiologic complaints in a patient, it can suggest that the patient is grieving for a loss.
The nurse knows that the diagnosis of contact latex allergy is based on history and ____.
- A. Latex specific IgE
- B. finding IgE in serum
- C. skin patch test
- D. ELISA
Correct Answer: C
Rationale: The diagnosis of contact latex allergy is primarily based on the patient's history of exposure to latex-containing products and the development of symptoms upon contact with latex. To confirm the diagnosis, skin patch testing is performed. Skin patch testing exposes the skin to small amounts of latex allergens to observe for any localized allergic reaction, such as redness, swelling, or itchiness. This test helps determine if the individual has developed a delayed-type hypersensitivity reaction to latex. Latex-specific IgE testing (choice A) and finding IgE in serum (choice B) are methods used in diagnosing immediate-type latex allergy but are not sufficient for confirming contact latex allergy specifically. ELISA (choice D) is a type of laboratory technique used for various purposes, including measuring the levels of specific substances in the blood, but it is not typically used as a diagnostic tool for contact latex allergy.
The patient seems indecisive whether to breastfeed her baby or not. Which is the desired nursing action of Nurse Vera to help the pregnant patient make a decision on breastfeeding?
- A. Give pamphlets and books to read.
- B. Provide ample time for the patient to decide.
- C. Refer the patient to the nutrionist.
- D. Assist to identify breastfeeding goal and plan.
Correct Answer: D
Rationale: The desired nursing action to help the pregnant patient make a decision on breastfeeding is to assist in identifying a breastfeeding goal and plan. When patients are indecisive about breastfeeding, it is essential for the nurse to support them in setting specific goals and creating a plan that aligns with their values and circumstances. This approach can help the patient feel empowered and confident in their decision-making process. Providing pamphlets and books (choice A) may be helpful, but personalized assistance in identifying a breastfeeding goal and plan is more likely to address the patient's individual needs and concerns. Providing ample time for the patient to decide (choice B) is important, but guidance and support in setting a clear goal can facilitate the decision-making process. Referring the patient to a nutritionist (choice C) may be beneficial for dietary concerns but may not directly address the decision-making process regarding breastfeeding.
For the students better understanding about the anatomy of the breast, the CI shares ________.
- A. various pictures of the breast, external and internal Views
- B. pictures of different types of mastectomies
- C. the experiences of breastfeeding mothers
- D. artistic drawings of the breasts
Correct Answer: A
Rationale: To help the students better understand the anatomy of the breast, it is crucial to provide visual aids that display both external and internal views of the breast. By sharing various pictures of the breast, students can visually learn about the structure, shape, location of different components, such as lobes, ducts, glands, and lymph nodes. Visual aids enhance the learning experience by providing a clear representation of the complex anatomical features of the breast, aiding in retention and comprehension. This approach can effectively supplement theoretical knowledge with practical visual references, facilitating a comprehensive understanding of breast anatomy.
Lillian asks the nurse the cause of this ailment. Which of the following would the nurse explain as predisposing factors of mastitis? (Select all that apply) I. Milk stasis II. Nipple trauma III. Using alcohol in cleaning nipples IV. Baby 's sitting position
- A. II and IV
- B. I and II
- C. I and IV
- D. II and III
Correct Answer: B
Rationale: Mastitis is typically caused by bacterial infection, with predisposing factors including milk stasis (I) and nipple trauma (II). Milk stasis occurs when milk is not effectively removed from the breast, leading to a build-up that can block ducts and predispose to infection. Nipple trauma, such as cracks or damage, can provide entry points for bacteria to infect the breast tissue. Factors like using alcohol in cleaning nipples (III) and the baby's sitting position (IV) are not directly associated with the development of mastitis.
