Question 1 of 5
While planning for proportionate distribution of restricted fluid volumes, what is the reason for a nurse to ensure that the client is actively involved during the development of the plan?
Correct Answer: A
Rationale: It is essential for a nurse to ensure that the client is actively involved in the development of the plan for proportionate distribution of restricted fluid volumes because it promotes the client's compliance with therapy. When the client participates in creating the plan, they are more likely to understand the importance of following it and be motivated to adhere to the recommended fluid restrictions. This active involvement fosters a sense of ownership and responsibility, leading to better treatment outcomes and improved overall health.
Question 2 of 5
The most common buffer system in the body is the:
Correct Answer: D
Rationale: The most common buffer system in the body is the bicarbonate-carbonic system. This system plays a crucial role in maintaining the pH balance in the blood. The bicarbonate ion (HCO3-) acts as a weak base, while carbonic acid (H2CO3) acts as a weak acid. The balance between these two components helps to regulate the pH of the blood.
Question 3 of 5
A client with ascites has a paracentesis, and 1500 ml of fluid is removed. Immediately following the procedure it is most important for the nurse to observe for:
Correct Answer: C
Rationale: Following a paracentesis procedure where a large amount of ascitic fluid is removed, there is a risk of developing a fluid shift and a potential complication known as "paracentesis-induced circulatory dysfunction" (PICD). This may cause a sudden increase in central blood volume due to rapid re-distribution of fluid, leading to respiratory congestion, dyspnea, and hypoxemia. Therefore, it is crucial for the nurse to monitor the client closely for signs of respiratory distress or congestion immediately after the procedure to prevent any respiratory complications. A rapid, thready pulse (choice A) may indicate hypovolemia, but it is not the most important immediate concern in this case. Decreased peristalsis (choice B) and an increased temperature (choice D) are not typically associated with the immediate post-paracentesis period and are therefore lower priorities compared to monitoring for signs of respiratory congestion.
Question 4 of 5
A pregnant client with hypertension and cardiac dysrhythmias is admitted to the hospital. Which of the following imbalances should the nurse check for?
Correct Answer: C
Rationale: Hypomagnesemia (low magnesium levels) should be checked for in a pregnant client with hypertension and cardiac dysrhythmias because magnesium plays a critical role in maintaining normal cardiac function and blood pressure regulation. It can worsen both hypertension and dysrhythmias if deficient. Hypomagnesemia can lead to cardiac arrhythmias, particularly in the setting of existing cardiovascular conditions. Monitoring and addressing magnesium levels is important in managing these conditions and ensuring maternal and fetal well-being during pregnancy. Checking for hypomagnesemia allows for timely intervention and correction to help prevent any complications.
Question 5 of 5
The physician orders furosemide (Lasix) 40 mg IV STAT for an acutely fluid-overloaded patient. Why was the IV route likely chosen?
Correct Answer: B
Rationale: The IV route was likely chosen for the administration of furosemide (Lasix) in this acutely fluid-overloaded patient because IV is the route of choice when rapid administration is needed. When given intravenously, the medication is able to produce a quicker and more immediate diuretic effect compared to oral administration, allowing for more rapid relief of fluid overload symptoms. This can be crucial in emergency situations where the patient's condition requires fast intervention.
