Classify Aneurysms.

Correct Answer: A

Rationale: The correct answer is A: Arterial aneurysm. Aneurysms are abnormal bulges or ballooning in the walls of arteries. They can occur in any artery in the body. Arterial aneurysms are the most common type and can be further classified based on their shape and location. Venous aneurysms (B) occur in veins, not arteries. Dissecting aneurysms (C) involve a tear in the inner layer of the artery wall, causing blood to flow between the layers. Fusiform aneurysms (D) are a type of arterial aneurysm characterized by a uniform dilation of the entire circumference of the artery.

Correct Answer: D

Rationale: The correct answer is D: bed rest. Bed rest is crucial for managing thrombophlebitis to prevent further clot formation and reduce the risk of complications. Movement can dislodge blood clots, leading to embolism. Analgesics (A) may help with pain but do not address the underlying issue. Anticoagulants (B) are used to prevent clot formation but do not directly manage pain. Exercise (C) can worsen thrombophlebitis by increasing the risk of clot dislodgment. Thus, bed rest is the most appropriate option for pain management in thrombophlebitis.

Correct Answer: A

Rationale: The correct answer is A: Mr. Baker's blood pressure remains uncontrolled because he is not taking his medicine as ordered. Medication adherence is crucial for managing blood pressure. If Mr. Baker is not taking his medicine as prescribed, it can lead to uncontrolled blood pressure. Choices B, C, and D may also contribute to high blood pressure, but not taking medication as ordered is the most likely reason based on the information provided. Choice B focuses on diet, which is important but not the most likely reason in this scenario. Choice C mentions sedentary behavior, which can impact blood pressure but is not as critical as medication adherence. Choice D addresses smoking, which is a risk factor for high blood pressure but not the primary reason in this case.

Correct Answer: C

Rationale: Step-by-step rationale for why the correct answer is C: a diuretic. 1. Diuretics promote the excretion of excess water and salt from the body, reducing fluid volume in the bloodstream. 2. Administering a diuretic can help manage conditions like hypertension and heart failure by decreasing blood pressure and relieving edema. 3. Diuretics are commonly used to treat conditions where fluid retention is a concern. 4. In the given scenario, anticipating administering a diuretic would be appropriate to address potential fluid overload or edema. Summary: A: Analgesics are used for pain relief, not for addressing fluid retention or volume overload. B: Catecholamines are hormones involved in the body's fight-or-flight response and are not typically used to manage fluid balance. D: Nitroglycerin is a vasodilator used to treat angina and heart-related chest pain, not fluid retention issues.

Correct Answer: B

Rationale: The correct answer is B. Increased heart rate and shallow painful respirations are indicative of pulmonary embolism. Increased heart rate is a common response to decreased oxygen levels due to impaired blood flow from a clot in the pulmonary arteries. Shallow, painful respirations can occur due to chest pain and difficulty breathing associated with pulmonary embolism. Decreased urine output and elevated central venous pressure (Choice A) are more indicative of heart failure or renal issues. Elevated temperature and decreased skin turgor (Choice C) are signs of dehydration or infection. Abdominal tenderness and decreased capillary refill (Choice D) are more suggestive of intra-abdominal issues like appendicitis or bowel obstruction.
