An adult has a central line in his right subclavian vein. The nurse is to change the tubing. Which of the following should be done?
- A. Use the present solution with the new tubing
- B. Connect the new tubing to the hub prior to running any fluid through the tubing
- C. Close the roller clamp on the new tubing after priming it
- D. Have the client roll to the right side to prevent an air embolus
Correct Answer: C
Rationale: The correct action to be taken when changing the tubing of a central line in the right subclavian vein is to close the roller clamp on the new tubing after priming it. This step is important to prevent air from entering the central line, which can lead to an air embolus. Proper priming and ensuring that the tubing is connected securely are essential steps in maintaining the integrity and safety of the central line system. Therefore, closing the roller clamp after priming the new tubing is crucial to prevent complications.

- A. Hypocalcamia
- B. hypokalemia
- C. Hypercalcemia
- D. Hyperkalemia

The normal range of hemoglobin in the blood of an adult:
- A. 7-11 mg
- B. 14-20 mg
- C. 12-18 mg
- D. 20-26 mg
Correct Answer: C
Rationale: The normal range of hemoglobin in the blood of an adult is typically between 12-18 grams per deciliter (g/dL). Hemoglobin is a protein found in red blood cells that is responsible for carrying oxygen from the lungs to the tissues in the body. Having an adequate level of hemoglobin is essential for proper oxygen delivery throughout the body. Values outside of the normal range may indicate anemia (low hemoglobin levels) or other underlying health conditions. It's important to consult a healthcare provider for interpretation of specific hemoglobin test results.
Which of the following outcomes would indicate successful treatment of diabetes insipidus?
- A. Fluid intake of less than 2,500mL
- B. Blood pressure of 90/50mmHg
- C. Pulse rate of 126 beats/min
- D. Urine output of more than 200mL/hour
Correct Answer: A
Rationale: Successful treatment of diabetes insipidus is indicated when the patient's excessive urination (polyuria) and thirst (polydipsia) are controlled. One of the primary goals of treatment is to achieve fluid balance by reducing urine output and, consequently, decreasing the excessive thirst. When the fluid intake is less than 2,500mL, it suggests that the patient's excessive thirst has decreased, indicating successful management of the condition. Monitoring and managing fluid intake are crucial in the treatment of diabetes insipidus to prevent dehydration and electrolyte imbalances. A lower fluid intake is a positive indicator that the treatment is effectively addressing the increased urine output characteristic of diabetes insipidus.

which of the following blood tests results is the most indicative of an improvement in rheumatic fever child?
- A. WBCS 11,000
- B. decrease ESR
- C. elevated ASOT
- D. hemoglobin 10 gm/dl.
Correct Answer: B
Rationale: Erythrocyte Sedimentation Rate (ESR) is a non-specific marker for inflammation and can be elevated in conditions like rheumatic fever. A decrease in ESR suggests a reduction in the inflammatory response in the body, indicating an improvement in the condition. While the other parameters (WBC count, ASOT, and hemoglobin level) may be affected in rheumatic fever, a decrease in ESR is a more direct indicator of improvement in the inflammatory process associated with the disease.
