Nursing Process 1 Test Questions

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: 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: 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: A

Rationale: The correct answer is A: Rice and lean chicken. A low residue diet aims to reduce fiber intake to ease digestion. Rice and lean chicken are low in fiber and easy to digest. Pasta with vegetables (B) contains high-fiber vegetables. Strawberry pie (C) is high in fiber due to fruit and crust. Tuna casserole (D) may contain high-fiber ingredients like noodles and vegetables. Therefore, A is the best choice for a low residue diet.

Correct Answer: B

Rationale: The correct answer is B: Focused assessment. In this scenario, the nurse is continuously monitoring specific aspects such as vital signs, pupils, and orientation at regular intervals, which is characteristic of a focused assessment. This type of assessment allows the nurse to gather specific data related to the client's condition and respond promptly to any changes. A: Initial assessment is conducted upon admission to establish baseline data. C: Time-lapsed reassessment involves comparing current data to previous assessments over a longer period. D: Emergency assessment is performed in urgent situations to quickly identify life-threatening issues. By systematically assessing the client's vital signs, pupils, and orientation at frequent intervals, the nurse can provide timely and appropriate care in the intensive care unit setting.
