Which of the following is the humoral immune response?
- A. B cells phagocytise the foreign antigen
- B. T cells are stimulated by B cells and turn into plasma cells, which produce antibodies or memory cells.
- C. B cells are stimulated by T helper cells or macrophages and turn into plasma cells, which produce antibodies or memory cells.
- D. T cells produce antibodies.
Correct Answer: C
Rationale: The humoral immune response involves the activation of B cells, which are stimulated by T helper cells or macrophages. When B cells are activated, they differentiate into plasma cells that produce antibodies specific to the foreign antigen. These antibodies can neutralize pathogens, tag them for destruction by other immune cells, or activate the complement system. In addition to producing antibodies, memory B cells are also generated during this process, providing long-lasting immunity upon re-exposure to the same antigen. This coordinated response is an essential part of the adaptive immune system's defense mechanism against foreign invaders.

The most effective pharmacologic agent for the treatment of Parkinson's disease is:
- A. Levodopa
- B. Selegilene
- C. Permax
- D. Symmetrel
Correct Answer: A
Rationale: Levodopa is considered the most effective pharmacologic agent for the treatment of Parkinson's disease. Levodopa is a precursor of dopamine, a neurotransmitter that is deficient in Parkinson's disease. By increasing dopamine levels in the brain, levodopa helps to alleviate the motor symptoms of Parkinson's disease, such as tremors, stiffness, and slowness of movement. Levodopa is often combined with another medication called carbidopa to enhance its effectiveness and reduce side effects. While other medications like selegiline, pergolide (Permax), and amantadine (Symmetrel) can also be used to manage Parkinson's disease symptoms, levodopa remains the primary and most effective treatment option for many patients.
A 34 year old male client is diagnosed with encephalitis. Medication has been started for him and he is receiving nursing care. Which of the ff nursing interventions are the most critical for such a client? Choose all that apply
- A. Measuring fluid intake and output
- B. Evaluating the clients ventilation capacity and lung sound frequently
- C. Observing closely for signs of respiratory distress
- D. Administering an indwelling urethral catheter
Correct Answer: B
Rationale: B. Evaluating the client's ventilation capacity and lung sounds frequently is crucial in encephalitis because the inflammation of the brain can affect the respiratory center, leading to respiratory compromise. Any changes in ventilation capacity or abnormal lung sounds should be addressed immediately to prevent respiratory distress.
Austin, age 6 months, has six teeth. How should the nurse interpret this finding?
- A. Normal tooth eruption
- B. Delayed tooth eruption
- C. Unusual and dangerous
- D. Earlier-than-normal tooth eruption
Correct Answer: A
Rationale: The eruption of teeth in infants typically begins around 6 months of age, with the lower central incisors being the first to appear. Having six teeth at 6 months old is within the normal range of tooth eruption for infants. The average time frame for infants to have their first teeth is between 4 to 7 months, so Austin's situation falls within that range. There is no cause for concern or interpretation of the finding as unusual or dangerous in this scenario.
A client is admitted for postoperative assessment and recovery after surgery for a kidney tumor. The nurse needs to assess for signs of urinary tract infection. Which of the ff measures can be used to help detect UTI?
- A. Encourage the client to breathe deeply and cough every 2hrs
- B. Monitor temperature every 4hrs
- C. Splint the incision when repositioning the client
- D. Irrigate tubes as ordered CARING FOR CLIENTS WITH DISORDERS OF THE BLADDER AND URETHRA
Correct Answer: B
Rationale: Monitoring temperature every 4 hours is crucial in detecting signs of a urinary tract infection in a postoperative client. An increase in temperature can indicate the presence of an infection, and early identification is essential for prompt treatment. While coughing and deep breathing (Option A) are beneficial for postoperative clients to prevent respiratory complications, they are not directly related to detecting UTI. Splinting the incision (Option C) is important for incisional care but does not specifically help in detecting UTI. Irrigating tubes (Option D) should only be done as ordered by the healthcare provider and is not a routine measure for detecting UTI.
