Question 1 of 5
Sodium bisulfite is a component of local anesthetic solution whose function is
Correct Answer: B
Rationale: Sodium bisulfite is commonly added to local anesthetic solutions as a vasoconstrictor. Vasoconstrictors work by constricting blood vessels at the site of injection. This helps to reduce blood flow to the area, which in turn decreases bleeding, prolongs the anesthetic effect, and reduces the risk of systemic toxicity by slowing the absorption of the anesthetic into the bloodstream. Sodium bisulfite specifically acts as a vasoconstrictor in local anesthetics to enhance the overall effectiveness of the numbing agent.
Question 2 of 5
With regard to non-depolarising neuromuscular blocking drugs:
Correct Answer: A
Rationale: Pancuronium is primarily renally eliminated, a true statement, prolonged in kidney failure. Rocuronium, a steroidal agent, not isoquinolone (like atracurium), is false. Rocuronium is hepatically metabolized, not via Hofmann elimination (atracurium does), so that's false. Vecuronium is mostly biliary excreted, not renal, making that false. Atracurium uses plasma esterases and Hofmann elimination, not pseudocholinesterases alone. Pancuronium's renal clearance is critical for surgical planning, especially in renal patients.
Question 3 of 5
A patient on diuretic therapy calls the clinic because he™s had the flu, with terrible vomiting and
Correct Answer: A
Rationale: The correct statement by the nurse is to instruct the patient to "stop taking the diuretic for a few days, and then restart it when you feel better." This is because the patient has been experiencing vomiting due to influenza, which can cause dehydration. Continuing the diuretic while experiencing such significant fluid loss can lead to further dehydration and electrolyte imbalances. It is important for the patient to pause the diuretic temporarily to allow the body to recover and then resume once the vomiting has subsided and hydration has improved. It's always best for patients to follow specific instructions given by healthcare providers in such situations.
Question 4 of 5
When teaching a patient about antihypertensive drug therapy, which statements by the nurse are correct? (Select all that apply.)
Correct Answer: A
Rationale: A. You need to have your blood pressure checked once a week and keep track of the readings. - This statement is correct because monitoring blood pressure regularly is essential when taking antihypertensive medications to ensure they are effectively controlling hypertension.
Question 5 of 5
Which of the following is the priority nursing diagnosis for a client undergoing chemotherapy?
Correct Answer: C
Rationale: When a client is undergoing chemotherapy, the priority nursing diagnosis would be related to potential complications from the treatment. Decreased cardiac output is a critical concern because certain chemotherapy drugs can have cardiotoxic effects, leading to reduced heart function. Monitoring and addressing any changes in cardiac output are vital for the overall well-being of the client during chemotherapy. While the other options may also be relevant, such as managing fear, anxiety, and altered nutrition, decreased cardiac output takes precedence due to its immediate impact on the client's cardiovascular health.
