Correct Answer: A

Rationale: During illness, individuals with type 1 diabetes mellitus may experience increased insulin requirements due to factors such as stress and the release of counterregulatory hormones. Increasing the frequency of self-monitoring, as stated in choice A, is crucial to closely monitor and adjust insulin doses as needed. Choice B, reducing food intake to alleviate nausea, is incorrect as it may lead to hypoglycemia and does not address the increased insulin needs during illness. Choice C, discontinuing the insulin dose if unable to eat, is dangerous as it can result in uncontrolled hyperglycemia. Choice D, taking the normal dose of insulin, may not be sufficient during illness when insulin requirements are likely elevated.

Correct Answer: D

Rationale: The correct answer is D: Stroke. Hypertension can lead to stroke due to the increased pressure on blood vessels in the brain, which can result in reduced blood flow and oxygen to the brain tissue. While choices B (Heart failure) and C (Kidney failure) can be complications of hypertension, they are not as directly associated as stroke. Choice A, Diabetes, is not a direct complication of hypertension but rather a separate condition that can be influenced by various factors. However, stroke is more commonly linked to the increased pressure on blood vessels in the brain in individuals with hypertension.

Correct Answer: A

Rationale: The most important nursing action when administering a blood transfusion is monitoring the patient's blood pressure. This is crucial because monitoring blood pressure allows for the prompt identification of any signs of adverse transfusion reactions, such as transfusion reactions or fluid overload. Immediate intervention can be initiated if any complications arise. While monitoring temperature, heart rate, and oxygen saturation are also essential aspects of patient care, they are not as critical as blood pressure monitoring during a blood transfusion. Therefore, the correct answer is to monitor the patient's blood pressure.

Correct Answer: A

Rationale: Escherichia coli is the most common cause of urinary tract infections (UTIs). It is responsible for the majority of UTIs, especially in women. E. coli is a normal inhabitant of the bowel and can enter the urinary tract through the urethra, leading to infection. Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae are less common causes of UTIs compared to E. coli. Staphylococcus aureus typically causes skin and soft tissue infections, Pseudomonas aeruginosa is more commonly associated with healthcare-associated infections, and Klebsiella pneumoniae is known for causing pneumonia and other respiratory infections.

Correct Answer: A

Rationale: Elevating the head of the bed to 30 degrees is crucial for a patient with increased intracranial pressure (ICP) because it helps promote venous drainage from the brain, thereby reducing ICP. Keeping the head of the bed elevated helps facilitate cerebral perfusion and can prevent a further increase in ICP. Administering diuretics (Choice B) may be considered in some cases to reduce fluid volume, but it is not the most critical intervention for immediate ICP management. Administering corticosteroids (Choice C) is not typically indicated for managing increased ICP unless there is a specific underlying condition requiring their use. Keeping the patient in a supine position (Choice D) can actually worsen ICP by impeding venous outflow from the brain, making it an incorrect choice for this scenario.
