Correct Answer: D

Rationale: In cases of magnesium sulfate toxicity, calcium gluconate is the antidote that should be administered promptly. Positioning the client supine (Choice A) is not the priority in this scenario. Administering dextrose 5% in water (Choice B) is not indicated for magnesium sulfate toxicity. Methylergonovine IM (Choice C) is used for postpartum hemorrhage, not for magnesium sulfate toxicity.

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: A

Rationale: Acknowledging the client's feelings and allowing them space demonstrates understanding and respect for their emotions.

Correct Answer: B

Rationale: The correct answer is to consult with a dietitian to create a high-protein diet. A serum albumin level of 3 g/dL indicates hypoalbuminemia, which can impair wound healing. Consulting with a dietitian to optimize the client's protein intake is crucial in promoting wound healing for pressure ulcers. Increasing the protein intake in the diet (Choice A) may not be sufficient without proper guidance from a dietitian. Increasing the IV fluid infusion rate (Choice C) is not directly related to addressing the protein deficiency. Administering a protein supplement (Choice D) should be guided by a healthcare professional's recommendation after consulting with a dietitian.

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.
