Question 1 of 5
Restoration of blood flow results through the dissolution of clot by:
Correct Answer: B
Rationale: Plasmin is an enzyme that is responsible for breaking down fibrin, a protein that forms blood clots. When an area of vessel needs to have its blood flow restored, such as after a clot has formed, plasmin is activated to dissolve the clot. By breaking down the fibrin mesh of the clot, plasmin helps restore normal blood flow in the affected vessel. Therefore, the restoration of blood flow results through the dissolution of clot by plasmin, making option B the correct answer.
Question 2 of 5
Which instruction(s) will the nurse include when teaching patients about gentamicin? (Select all that apply.)
Correct Answer: A
Rationale: Gentamicin is an aminoglycoside antibiotic associated with ototoxicity, which can manifest as hearing loss or tinnitus. Patients should be instructed to report any changes in hearing. Sunscreen is not specifically required for gentamicin, as it does not cause photosensitivity. Intravenous gentamicin is typically infused over 30-60 minutes, not 20 minutes. Monitoring for mouth ulcers and vaginitis is not a priority with gentamicin, but renal function and ototoxicity should be closely monitored.
Question 3 of 5
The nurse is discharging a 35-year-old patient with diabetes who has been prescribed an adrenergic blocking agent. What is the priority teaching point for the nurse to discuss with this patient?
Correct Answer: A
Rationale: It is important for the patient to be instructed to monitor blood sugar levels more frequently because adrenergic blocking agents mask the normal hypo- and hyperglycemic manifestations that normally alert patients such as sweating, feeling tense, increased heart rate, and rapid breathing. There is no need to change the diet or the diabetic medications. There may be no signs and symptoms to record because they are blocked by the adrenergic blocker. The nurse should emphasize the importance of frequent blood glucose monitoring and reporting any instability to the healthcare provider.
Question 4 of 5
A patient in the clinic reports difficulty tolerating the current ACE inhibitor medication, and questions if another medication could be used. The nurse correctly suspects the prescriber will choose which medication, which affects the renin-angiotensin-aldosterone system?
Correct Answer: B
Rationale: Losartan is an angiotensin II receptor blocker (ARB) that affects the renin-angiotensin-aldosterone system (RAAS) and is often used as an alternative to ACE inhibitors. Atenolol (A) is a beta-blocker, spironolactone (C) is a potassium-sparing diuretic, and adenosine (D) is used for arrhythmias. ARBs like losartan are preferred for patients who cannot tolerate ACE inhibitors due to side effects like cough or angioedema.
