Correct Answer: A

Rationale: The correct answer is A: Orthostatic hypotension. In a patient with congestive heart failure, there is impaired cardiac function leading to decreased cardiac output. This can result in orthostatic hypotension, where blood pressure drops upon standing. Monitoring for orthostatic hypotension is important to prevent falls and other complications. B: Hyperkalemia is not typically associated with congestive heart failure. C: Hypoglycemia may occur in patients with diabetes, but it is not a common complication of congestive heart failure. D: Severe dehydration is not directly related to congestive heart failure unless the patient has concurrent issues such as diarrhea or excessive diuresis.

Correct Answer: A

Rationale: The correct answer is A: Immobilize the client. This is crucial to prevent further damage to the spinal cord. Moving a client with a suspected spinal cord injury can worsen the injury and lead to permanent damage. Immobilizing the client helps maintain spinal alignment and reduces the risk of paralysis. Providing pain relief (B) and loosening clothing (D) are important but secondary actions. Applying pressure to the chest (C) is not recommended for a suspected spinal cord injury as it can also exacerbate the injury.

Correct Answer: D

Rationale: The correct answer is D: All of the above. This is the best choice because reducing the risk of another stroke requires a holistic approach. A: Limiting sodium and cholesterol intake helps manage blood pressure and cholesterol levels, reducing the risk of stroke. B: Increasing physical activity and managing weight can improve cardiovascular health and overall well-being, reducing the risk of stroke. C: Taking prescribed medications regularly, such as blood thinners or antihypertensives, is crucial in preventing another stroke. In summary, all three choices address key risk factors for stroke prevention, making them essential components of a comprehensive stroke prevention plan.

Correct Answer: D

Rationale: The correct answer is D: Administer corticosteroids. In a client with chest pain and a history of myocardial infarction, the first priority is to address potential inflammation in the myocardium. Corticosteroids help reduce inflammation and stabilize the myocardium, which is crucial in preventing further damage post-myocardial infarction. Administering nitroglycerin (A) is important for vasodilation, but it is typically used after corticosteroids. Morphine (B) and analgesics (C) may provide pain relief but do not address the underlying inflammation. Administering corticosteroids is the most appropriate first step to manage myocardial inflammation and protect the heart tissue.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators. During an acute asthma attack, bronchodilators are the first-line treatment to quickly relieve bronchospasm and improve airflow. They work by relaxing the muscles around the airways, allowing the client to breathe easier. Administering corticosteroids (choices B and C) is important but typically done after bronchodilators to reduce airway inflammation. Encouraging fluid intake (choice D) is not the priority in an acute asthma attack, as the focus should be on addressing the breathing difficulty promptly.
