Correct Answer: B

Rationale: The correct answer is B because the client should take antitubercular medications for a minimum of 6 months to ensure complete eradication of the infection. Choice A is incorrect as stopping the medication early can result in treatment failure and development of drug-resistant TB. Choice C is incorrect as regular TB skin tests are not needed once the client has been diagnosed and treated. Choice D is incorrect as wearing a mask at all times is not necessary for a client with active TB; proper cough etiquette should be followed instead.

Correct Answer: A

Rationale: Using a bed exit alarm system is crucial in minimizing the risk of injury for a client with dementia. This intervention helps alert staff when the client is attempting to leave the bed, reducing the chances of falls. Raising all four side rails while the client is in bed (Choice B) can lead to restraint-related issues and is not recommended unless necessary for safety reasons. Applying a soft wrist restraint (Choice C) is generally not the first choice in managing clients with dementia due to the risk of complications and loss of mobility. Dimming the lights in the client's room (Choice D) may not directly address the risk of injury associated with dementia and may even increase the risk of falls due to poor visibility.

Correct Answer: A

Rationale: The correct answer is to insert a chest tube. This intervention is considered the definitive treatment for a pneumothorax as it helps remove air or fluid from the pleural space, re-expanding the lung. Administering oxygen (Choice B) can be supportive but is not the primary intervention to treat a pneumothorax. Monitoring respiratory rate (Choice C) is important but does not address the underlying issue of air in the pleural space. Administering analgesics (Choice D) may help manage pain but does not treat the pneumothorax itself.

Correct Answer: C

Rationale: The correct answer is C: 'Consume foods high in fiber.' Consuming high-fiber foods helps manage symptoms of ulcerative colitis by promoting regular bowel movements. Choices A, B, and D are incorrect. Avoiding high-fiber foods can worsen symptoms as fiber is beneficial for digestive health. Increasing the intake of spicy foods can exacerbate inflammation in the digestive tract, leading to more discomfort. Eating large, infrequent meals can put more strain on the digestive system, which is not ideal for managing ulcerative colitis.

Correct Answer: A

Rationale: Boiled spinach is an excellent source of iron, making it a top choice for individuals with iron deficiency anemia. Spinach contains non-heme iron, which may not be absorbed as efficiently as heme iron from animal sources but is still beneficial. Raw carrots, boiled chicken, and yogurt are not as rich in iron compared to spinach. Carrots are more known for their beta-carotene content, chicken is a good source of protein but not high in iron, and yogurt does not contain significant amounts of iron.
