1. Sputum examination is the major screening tool for pulmonary tuberculosis. Clients may sometimes receive false negative results in this exam. This means that the test is not perfect in terms of which characteristic of a diagnostic examination?

Correct answer: D

Rationale: Sensitivity is the ability of a diagnostic test to correctly identify individuals with the disease. A test with high sensitivity will rarely give false negative results, as it will detect almost all positive cases. In the context of the given scenario, false negative results indicate that the test is lacking in sensitivity to pick up all cases of pulmonary tuberculosis, leading to some cases being missed.

2. During a home visit, the PHN bag is a crucial tool for providing nursing care. The most important principle in bag technique states that it:

Correct answer: B

Rationale: The bag technique is a vital practice to prevent the transmission of infections to and from the client during home visits. By following proper bag technique procedures, nurses can minimize, if not entirely prevent, the spread of infections between themselves and their clients, ensuring a safe care environment.

3. What is the primary method of transmission for tuberculosis?

Correct answer: B

Rationale: The correct answer is 'Airborne.' Tuberculosis is mainly transmitted through the air via respiratory droplets when an infected person coughs or sneezes. This allows the bacteria to be inhaled by others and infect their lungs. It is important to implement infection control measures to prevent the spread of tuberculosis in healthcare settings and the community.

4. Which of the following is a contraindication for the administration of live vaccines?

Correct answer: B

Rationale: A previous allergic reaction to the vaccine is a contraindication for the administration of live vaccines. This is because individuals who have had a previous allergic reaction to a vaccine are at higher risk of developing a severe allergic reaction with subsequent doses. It is crucial to identify and avoid administering live vaccines to individuals with a history of allergic reactions to prevent potential adverse events.

5. When educating a mother about the benefits of breastfeeding, what should be included?

Correct answer: B

Rationale: Breastfeeding provides passive immunity to the infant by transferring antibodies from the mother to protect the infant from infections and illnesses. This is one of the key benefits of breastfeeding, as it helps boost the baby's immune system during the early stages of life.
