Correct Answer: A

Rationale: The correct answer is A. An INR of 1.8 is below the therapeutic range for a client receiving warfarin, indicating a potential risk of blood clots. This value should be reported to the provider for further evaluation and possible adjustment of the warfarin dosage. Choices B, C, and D are within normal ranges and do not directly relate to the effectiveness or safety of warfarin therapy in this scenario, making them less urgent to report.

Correct Answer: A

Rationale: Corrected Rationale: Monitoring skin turgor is a reliable method to assess dehydration in elderly patients. Skin turgor refers to the skin's elasticity or the skin's ability to return to its normal position after being pinched. In dehydration, the skin loses its elasticity, becoming less flexible and slower to return to its original state. Checking for dry mucous membranes (Choice B), monitoring for sunken eyes (Choice C), and checking capillary refill (Choice D) are all relevant assessments in dehydration but are not as specific or sensitive as monitoring skin turgor. Dry mucous membranes and sunken eyes are indicators of dehydration, while capillary refill is more related to circulatory status and less specific to dehydration.

Correct Answer: A

Rationale: The correct way for a healthcare provider to monitor a patient with suspected deep vein thrombosis (DVT) is to check for leg swelling. Leg swelling is a common symptom of DVT and monitoring for this sign is crucial for early detection and intervention. Encouraging ambulation may be beneficial for preventing DVT but is not the recommended method for monitoring an existing condition. Checking for redness may be useful in cases of superficial thrombophlebitis but is not specific to DVT. Monitoring oxygen saturation is more relevant for respiratory or cardiovascular conditions, not for DVT.

Correct Answer: B

Rationale: The correct answer is B: Consume 15 grams of a fast-acting carbohydrate. Consuming 15 grams of a fast-acting carbohydrate, such as glucose tablets or juice, helps raise blood glucose levels quickly in cases of hypoglycemia. Choice A is incorrect because avoiding carbohydrate-rich foods during hypoglycemia can worsen the condition. Choice C is incorrect as drinking water does not effectively raise blood glucose levels. Choice D is incorrect as eating a snack before exercising is more related to preventing exercise-induced hypoglycemia, not managing hypoglycemia.

Correct Answer: D

Rationale: The correct answer is D because a temperature of 37.3°C (99.1°F) is slightly elevated, indicating a possible infection or inflammatory response, which should be reported to the provider for further evaluation. Choices A, B, and C are within normal limits for a client postoperative, so they do not require immediate reporting. Elevated temperature can be a sign of infection or other complications, making it a priority for reporting and further assessment.
