Correct Answer: B

Rationale: A bulging posterior fontanelle is a sign of increased intracranial pressure in infants, not a common symptom after a subdural hematoma. In the context of a subdural hematoma, a decreased level of consciousness is more indicative of a complication as it can be a sign of worsening brain function due to increased pressure on the brain from the collection of blood in the subdural space. Increased appetite and high-pitched cry are not typically associated with complications of a subdural hematoma.

Correct Answer: A

Rationale: The correct nursing intervention for a patient receiving anticoagulant therapy is to monitor INR levels and check for signs of bleeding. Monitoring the INR levels helps assess the effectiveness and safety of anticoagulant therapy, while checking for bleeding is essential due to the increased risk associated with anticoagulants. Choice B is incorrect as antiplatelet therapy is not the standard treatment for patients on anticoagulant therapy. Choice C is incorrect as providing additional anticoagulation is not a direct nursing intervention in this scenario. Choice D is incorrect because administering aspirin, an antiplatelet medication, along with anticoagulants can increase the risk of bleeding and is generally avoided.

Correct Answer: B

Rationale: The correct action the nurse should take first when noting excessive lochia discharge in a client who delivered a full-term newborn 16 hours ago is to perform a fundal massage. Fundal massage helps stimulate uterine contractions, which in turn reduces bleeding in postpartum clients. Administering pain medication (Choice A) is not the priority in this situation as addressing the excessive lochia discharge is crucial to prevent complications. Checking the baby's heart rate (Choice C) is important but not the first action to manage the mother's condition. Applying an ice pack (Choice D) is not appropriate for managing excessive lochia discharge; fundal massage is the initial intervention to address this issue effectively.

Correct Answer: A

Rationale: In a hypertensive crisis, the immediate goal is to lower blood pressure to prevent organ damage. Administering antihypertensive medications helps achieve this goal efficiently. Monitoring blood pressure is essential to assess the effectiveness of the treatment and adjust medication as needed. Providing a high-sodium diet and fluid restriction (Choice B) can exacerbate hypertension by increasing blood pressure. Diuretics and oxygen therapy (Choice C) are not the first-line treatment for hypertensive crisis, as the priority is rapid blood pressure reduction. Providing IV fluids and monitoring for kidney failure (Choice D) are not primary interventions for managing hypertensive crisis; the focus is on blood pressure control and organ protection.

Correct Answer: A

Rationale: Hypoglycemia typically presents with sweating and trembling, while hyperglycemia is characterized by frequent urination and thirst. Therefore, the correct key differences between hypoglycemia and hyperglycemia are that hypoglycemia includes symptoms like sweating and trembling, while hyperglycemia involves symptoms such as frequent urination and thirst. Choices B, C, and D are incorrect because they do not accurately represent the characteristic symptoms of hypoglycemia and hyperglycemia, as stated in the question.
