Which of the following fluid compartments is not a partner in immune function?

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. JV is a 16-year-old male with cystic fibrosis. He has been admitted several times to your pulmonary inpatient unit with multiple microorganism infections, including Pseudomonas and H. influenza. Because of the thickness of his mucous secretions, his cilia become immobile and unable to clear his lungs of bacteria harboring mucus. He is supposed to perform vigorous airway mucous clearance at home with a vibrating vest and IPV (intrapulmonary percussive ventilation) device. However, he says that it takes hours and he does not always feel sick. Therefore, he often refuses to do his therapies at home. -JV asks you,as his bedside nurse,to explain to him why he keeps getting sick from the same bacteria.What is an appropriate response?

Monocytes and lymphocytes are agranular leukocytes.

Each of the following are granulocytes except

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. The mother of 6-year-old Mary has brought her daughter into the pediatrician’s office where you work, complaining Mary has had a sore throat for several days and a fever. She has had a fever up to 104F that seems worse at night, but seems to respond to treatment with acetaminophen. Mary has not been eating or drinking as much either because she says “it hurts to swallow.” She is ill-appearing, and does not seem interested in playing with the toys or reading the books that are in the examination room. The doctor noted a thick, white exudate coating on both of Mary’s tonsils, which also seem enlarged. The doctor ordered a throat culture swab, as well as a complete blood count with differentials. -You initially examine Mary for yourself,and discover that lymph nodes at the posterior cervical chain of her neck seem warm,tender,and slightly enlarged.However,the other lymph nodes are either nonpalpable or small,nontender,rubbery,and less than 2 mm in size.What is your interpretation of this finding?

Components of the first line of defense include all the following except

Which white blood cells comprise 3% to 7% of circulating WBCs,are phagocytic,and can migrate out into body tissues to differentiate into macrophages?

Therefore, he often refuses to do his therapies at home. -JV is very intelligent and realizes that he needs to be more diligent with his mucus clearing exercises.He asks you if it is okay if he only does his exercises when he is not feeling well,even though the doctor tells him he must do them every day.What is a correct response?

During inflammation,a high neutrophil count is a common sign of bacterial infection.
