Correct Answer: D

Rationale: The correct answer is D: Tachycardia. In clients with hyperthyroidism, tachycardia is a common finding due to the increased metabolic rate. Weight loss and heat intolerance are also expected due to the elevated metabolism. Choices A, B, and C (Weight gain, dry skin, cold intolerance) are not typical findings in hyperthyroidism, as the condition is associated with an overactive thyroid gland leading to an increase in metabolic functions.

Correct Answer: A

Rationale: In a client with chronic kidney disease experiencing fluid volume overload, the nurse should expect a decreased blood pressure. Fluid volume overload can lead to poor cardiac output, which in turn can cause a decrease in blood pressure. Choices B, C, and D are incorrect. Increased urine output is not expected in fluid volume overload; decreased heart rate is not typically associated with fluid volume overload; and an increased heart rate is more commonly seen in response to fluid overload to compensate for the decreased cardiac output.

Correct Answer: B

Rationale: The correct answer is B: Platelet count 50,000/mm³. A platelet count of 50,000/mm³ increases the risk of bleeding, making heparin contraindicated. Platelets are essential for blood clotting, and a low count can lead to excessive bleeding. Choices A, C, and D are not contraindications to heparin administration. Hemoglobin level of 13 g/dL is within the normal range, white blood cell count of 6,000/mm³ is also normal, and an INR of 2.5 is within the therapeutic range for patients receiving heparin therapy.

Correct Answer: B

Rationale: The correct instruction for the nurse to include is to advise the client to monitor for black, tarry stools while taking clopidogrel. This is important because it helps detect gastrointestinal bleeding, a potential side effect of the medication. Choice A is incorrect as there is no specific requirement to avoid foods high in fat while taking clopidogrel. Choice C is incorrect as grapefruit juice interaction is not a concern with clopidogrel. Choice D is incorrect as clopidogrel can be taken with or without food.

Correct Answer: B

Rationale: Administering an intermittent enteral feeding through a gastrostomy tube requires flushing the tube with 10 mL of sterile water before feeding. This action helps ensure patency and prevents clogging. Choice A is incorrect because flushing after feeding does not address the need for pre-feeding tube flushing. Choice C is unrelated to tube feeding administration. Choice D is incorrect as the height of the feeding bag above the abdomen is typically regulated by healthcare facility policies and is not a universal standard.
