Nursing Process 1 Test Questions

Correct Answer: D

Rationale: The correct answer is D: leukocytosis. Carbamazepine can cause bone marrow suppression, leading to leukocytosis. Monitoring for elevated white blood cell count is essential to detect this potential complication early. A: Adult respiratory distress syndrome is not a common complication of carbamazepine. B: Elevated levels of phenytoin is not a direct complication of carbamazepine use. C: Diplopia is a common side effect of carbamazepine, not a potential complication like leukocytosis.

Correct Answer: B

Rationale: The correct answer is B because decorticate posturing is characterized by the flexion of elbows, wrists, and fingers, extension of elbows and knees, plantar flexion of feet. This pattern indicates damage to the cerebral hemispheres or internal structures of the brain. In contrast, option A describes decerebrate posturing, which indicates more severe brain damage. Option C is incorrect as it describes a mixed pattern of posturing. Option D is also incorrect as it describes a different type of posturing called decerebrate posturing.

Correct Answer: C

Rationale: The correct answer is C: Bone marrow. Blood cells are primarily formed in the bone marrow through a process called hematopoiesis. The bone marrow contains stem cells that differentiate into various types of blood cells, including red blood cells, white blood cells, and platelets. Arterioles are small blood vessels that carry blood away from the heart, not involved in blood cell formation. Lymphoid tissue plays a role in immune function but not in blood cell production. Muscle tissue is primarily responsible for movement and does not have a role in blood cell formation. Therefore, the bone marrow is the correct answer as it is the main site of blood cell production in the body.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Digoxin toxicity can be potentiated by hypokalemia due to the risk of enhanced cardiac toxicity. 2. Hypokalemia can lead to increased sensitivity of cardiac cells to digoxin. 3. Low potassium levels can disrupt the sodium-potassium ATPase pump, enhancing digoxin's effects. 4. The nurse should recognize hypokalemia as a predisposing factor for digoxin toxicity. Summary: A: Hypokalemia is the correct answer as it enhances digoxin toxicity by affecting cardiac function. B: Hyponatremia does not directly predispose to digoxin toxicity. C: Hyperkalemia is not a predisposing factor and can actually counteract digoxin's effects. D: Hypernatremia is not directly related to digoxin toxicity.

Correct Answer: A

Rationale: The correct answer is A: Vision changes. This is crucial to report immediately because tamoxifen can cause serious eye problems such as retinopathy. Vision changes could indicate a potentially serious adverse reaction that requires prompt medical attention to prevent permanent damage. Headache, hearing loss, and anorexia are not typically associated with tamoxifen use and are less urgent in nature. Reporting vision changes promptly can help prevent irreversible harm and ensure timely intervention.
