Correct Answer: A

Rationale: The correct answer is A: Hepatotoxicity. Isoniazid (INH) can lead to hepatotoxicity, necessitating the monitoring of liver function tests. This adverse effect is characterized by liver damage and dysfunction. Choices B, C, and D are incorrect because isoniazid is not typically associated with hyperglycemia, hypotension, or hypokalemia. Therefore, the nurse should focus on assessing for signs and symptoms of hepatotoxicity in a client receiving isoniazid.

Correct Answer: B

Rationale: After a segmental lung resection, the priority nursing action should be to suction excessive tracheobronchial secretions. This helps in preventing airway obstruction from secretions, ensuring the patency of the airway and optimizing respiratory function. Administering pain medication can be important but addressing airway clearance takes precedence. Assisting the client to turn, deep breathe, and cough is essential for respiratory hygiene but not the first action immediately post-op. Monitoring oxygen saturation is crucial, but ensuring airway clearance is the priority to prevent complications.

Correct Answer: B

Rationale: The correct answer is to select the best strategy for health action for people to implement because it empowers the community to take ownership of their health. Listening to people's problems (Choice A) is important, but the effectiveness lies in empowering them to implement solutions. Directing people's efforts (Choice C) can be directive and may not foster community ownership. Just telling clients what to do (Choice D) does not promote active participation and empowerment.

Correct Answer: C

Rationale: Tertiary care is the correct answer because it involves specialized care provided by medical centers and regional or provincial hospitals. Primary care (Choice B) refers to basic healthcare services usually delivered by general practitioners, nurses, and other healthcare professionals. Secondary care (Choice A) involves specialized services provided by medical specialists and other health professionals who generally do not have first contact with patients. Intermediate care (Choice D) is not a recognized level of care in the typical healthcare system hierarchy; it may cause confusion as it's not a standard term used to describe levels of care.

Correct Answer: B

Rationale: The most effective strategy in promoting breastfeeding in a community is offering breastfeeding education and support. This helps mothers learn about the benefits of breastfeeding, gain confidence in their ability to breastfeed, and receive necessary support to overcome challenges. Providing formula samples (Choice A) can undermine breastfeeding efforts by promoting formula feeding over breastfeeding. Encouraging early weaning (Choice C) goes against the recommendation of exclusive breastfeeding for the first six months of life. Promoting bottle feeding (Choice D) can deter mothers from initiating or continuing breastfeeding, leading to decreased breastfeeding rates.
