Question 1 of 5
Central venous access devices are beneficial in pediatric therapy because:
Correct Answer: B
Rationale: Central venous access devices are beneficial in pediatric therapy because they provide a reliable and convenient access point for administering medications, fluids, and blood products without restricting the use of a child's arms. This allows children to move freely and participate in activities while receiving necessary treatments, enhancing their comfort and quality of life.
Question 2 of 5
A patient is taken to the trauma unit after a motorcycle accident. It is estimated that he has lost 30% of his blood volume and he is in hypovolemic shock. The nurse anticipates a transfusion with which blood product?
Correct Answer: A
Rationale: In hypovolemic shock due to significant blood loss, the primary goal is to quickly restore the lost volume of red blood cells to improve tissue perfusion and oxygen delivery. Packed Red Blood Cells (PRBCs) are the most appropriate blood product for this situation as they contain a high concentration of red blood cells and minimal plasma, making them the most efficient way to replace lost red blood cells. Whole blood, Cryoprecipitate, and Fresh Frozen Plasma (FFP) contain other blood components which are not the immediate priority in this scenario.
Question 3 of 5
A patient who has recently started therapy on a statin drug asks the nurse how long it will take until he sees an effect on his serum cholesterol. Which statement would be the nurse™s best response?
Correct Answer: B
Rationale: The nurse's best response would be, "It takes 6 to 8 weeks to see a change in cholesterol levels." Statin drugs typically take around 6 to 8 weeks before a noticeable effect on serum cholesterol levels is seen. This timeframe allows the medication to fully take effect and lower the cholesterol levels in the blood. Patients should continue with the prescribed treatment regimen and have their cholesterol levels monitored regularly to assess the effectiveness of the medication.
Question 4 of 5
Two days after admission, the nurse is reviewing laboratory results of the patient. Which is the most common electrolyte finding resulting from the administration of furosemide (Lasix)?
Correct Answer: C
Rationale: The most common electrolyte finding resulting from the administration of furosemide (Lasix) is hypokalemia. Furosemide is a loop diuretic that works by blocking the reabsorption of sodium and chloride in the ascending loop of Henle in the kidneys. This results in increased excretion of water and electrolytes, including potassium. Hypokalemia can lead to various complications such as cardiac arrhythmias, muscle weakness, and fatigue.
Therefore, patients receiving furosemide should be closely monitored for potassium levels, and supplementation may be necessary to prevent and treat hypokalemia.
Question 5 of 5
A patient is concerned about the adverse effects of the fibric acid derivative she is taking to lower her cholesterol level. Which is an adverse effect of this class of medication?
Correct Answer: C
Rationale: Adverse effects of fibric acid derivatives, also known as fibrates, may include joint pain among other side effects such as gastrointestinal symptoms, abnormalities in liver function tests, and myopathy (muscle damage). Joint pain can be a result of musculoskeletal side effects associated with fibrates, so it is important for the patient to report any new or worsening joint pain to their healthcare provider.
