Correct Answer: A

Rationale: The correct teaching the nurse should provide to a client prescribed an inhaled corticosteroid is to rinse the mouth with water after using the inhaler. This helps prevent oral fungal infections, a common side effect of inhaled corticosteroids. Choice B is incorrect because inhaled corticosteroids are usually used regularly, not just during asthma attacks. Choice C is incorrect as using the inhaler before exercise can actually help prevent exercise-induced bronchospasm. Choice D is incorrect because cleaning the inhaler with hot water after each use is not necessary and may damage the device.

Correct Answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

Correct Answer: D

Rationale: Corrected Rationale: Blurred vision or seeing yellow halos around objects are signs of digoxin toxicity, which can be life-threatening. These symptoms indicate an overdose of digoxin, requiring immediate medical attention. Muscle weakness and fatigue (Choice A) are not typically associated with digoxin toxicity. Increased appetite and weight gain (Choice B) are not indicative of digoxin toxicity either. Nausea and vomiting (Choice C) are common side effects of digoxin but are not specific signs of toxicity. Therefore, the correct answer is to monitor for blurred vision or seeing yellow halos around objects.

Correct Answer: B

Rationale: The correct answer is B. Monitoring the client's compliance with NPO status is the priority assessment. Ensuring the client remains NPO (nothing by mouth) is crucial to reduce the risk of aspiration during surgery. Assessing the client's understanding of the procedure is important but not the priority at this moment. Checking vital signs is also essential but ensuring NPO status takes precedence for patient safety. Ensuring the client's consent form is signed is necessary but not the priority assessment compared to maintaining NPO status.

Correct Answer: B

Rationale: The correct answer is to check the client's blood glucose level. This is the priority action when dealing with a client admitted with hyperglycemia. Checking the blood glucose level helps determine the severity of hyperglycemia and guides further treatment. Administering insulin or fluids or monitoring intake and output are important interventions but should come after assessing the blood glucose level to inform the most appropriate course of action.
