Correct Answer: D

Rationale: The correct answer is D. An HbA1c level less than 7% indicates good long-term glucose control for clients with diabetes. This goal reflects optimal glycemic control and reduces the risk of long-term complications. Choices A, B, and C are incorrect because they do not represent appropriate goals for managing type 1 diabetes in an adolescent. An HbA1c level greater than 8% (choice A) signifies poor glucose control, while a blood glucose level greater than 200 mg/dL at bedtime (choice B) and a blood glucose level less than 60 mg/dL before breakfast (choice C) are not within the target ranges for safe and effective diabetes management.

Correct Answer: A

Rationale: The correct answer is A: Pulmonary embolism and stroke. Untreated DVT can result in these serious complications, emphasizing the importance of timely intervention. Choices B, C, and D are incorrect because they do not represent common complications associated with untreated deep vein thrombosis. Infection and kidney failure, hypertension and vision loss, as well as dehydration and electrolyte imbalance are not typically direct consequences of untreated DVT.

Correct Answer: A

Rationale: Creatinine is the correct answer. In acute kidney injury, creatinine levels are expected to be elevated due to impaired renal function. Magnesium, hemoglobin, and white blood cell count are not typically elevated in acute kidney injury. Magnesium levels may be affected in kidney disease, but elevation is not a common finding in acute kidney injury.

Correct Answer: B

Rationale: The correct intervention for a client with dementia at risk of falls is to use a bed exit alarm to notify staff when the client tries to leave the bed. This intervention helps prevent falls while still allowing some freedom of movement. Choice A is incorrect because using restraints can lead to complications and is considered a form of restraint which should be avoided. Choice C is not suitable for a client at high risk of falls due to dementia as it may increase the risk of falls. Choice D is not recommended as raising all four side rails can be considered a form of physical restraint and may not be the best approach to prevent falls in a client with dementia.

Correct Answer: A

Rationale: The correct answer is A: Chest pain, shortness of breath, and tachycardia. These are classic early signs of a pulmonary embolism. Chest pain may be sudden and sharp, worsened by deep breathing or coughing. Shortness of breath can be sudden and severe. Tachycardia (rapid heart rate) is another common symptom. Choices B, C, and D are incorrect as they do not represent typical early signs of a pulmonary embolism.
