Question 1 of 5
What is the purpose of “Tunneling†(inserting the catheter 2-4 inches under the skin) when the surgeon inserts a Hickman central catheter device?
Correct Answer: B
Rationale: Tunneling the catheter 2-4 inches under the skin creates a pathway that helps reduce the risk of infection. By placing the catheter deeper under the skin, there is less chance of bacteria entering the catheter exit site, which can lead to infections such as catheter-related bloodstream infections. Tunneling also promotes tissue ingrowth around the catheter, further helping to secure the catheter in place and reduce the risk of infection.
Question 2 of 5
The nurse is preparing for a community education program on hypertension. Which of these parameters determine the regulation of arterial blood pressure?
Correct Answer: A
Rationale: Arterial blood pressure is regulated by two main factors: cardiac output and systemic vascular resistance. Cardiac output refers to the amount of blood pumped by the heart per minute, while systemic vascular resistance refers to the resistance to blood flow in the systemic circulation. The combination of these two parameters determines the pressure within the arteries. If cardiac output or systemic vascular resistance increases, blood pressure will increase, and vice versa.
Therefore, when discussing the regulation of arterial blood pressure, focusing on cardiac output and systemic vascular resistance is crucial for understanding how the body maintains blood pressure within a normal range. The other choices, such as heart rate and peripheral resistance, blood volume and renal blood flow, as well as myocardial contractility and arteriolar constriction, are important factors in cardiovascular physiology but are not the primary determinants of arterial blood pressure regulation.
Question 3 of 5
When monitoring a patient who has diabetes and is receiving a carbonic anhydrase inhibitor for edema, the nurse will monitor for which possible adverse effect?
Correct Answer: B
Rationale: Carbonic anhydrase inhibitors such as acetazolamide are commonly used to treat edema by promoting diuresis. However, one notable adverse effect of carbonic anhydrase inhibitors in patients with diabetes is the potential to elevate blood glucose levels. These medications can lead to an increase in blood glucose due to their effect on renal glucose reabsorption, resulting in hyperglycemia.
Therefore, when monitoring a patient with diabetes who is receiving a carbonic anhydrase inhibitor for edema, it is crucial for the nurse to closely monitor the patient's blood glucose levels to prevent any adverse effects related to hyperglycemia.
Question 4 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 the case of a hypovolemic shock due to significant blood loss, the primary concern is to restore the lost blood volume quickly. Packed Red Blood Cells (PRBCs) contain a high concentration of red blood cells and are used to replenish oxygen-carrying capacity in cases of hemorrhage. PRBCs are the most appropriate blood product in this scenario as they can effectively increase the oxygen-carrying capacity of the blood without overloading the patient with excess fluid volume like whole blood. Whole blood contains not only red blood cells but also plasma and other components, which may not be necessary for immediate volume resuscitation. Cryoprecipitate and Fresh Frozen Plasma (FFP) are usually indicated for specific coagulation factor deficiencies and are not the primary choice for treating hypovolemic shock. Thus, in this case, PRBCs are the most suitable blood product to address the acute blood loss and restore
Question 5 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 start to show an effect on lowering cholesterol levels within 6 to 8 weeks of starting therapy. It may take some time for the medication to reach its maximum effectiveness, but a noticeable change can usually be seen within this time frame. Monitoring cholesterol levels through blood tests is important to assess the effectiveness of the medication and make any necessary adjustments to the treatment plan.
