Question 1 of 5
When preparing to apply dressing to a stage 2 pressure injury, which type of dressing should the nurse use?
Correct Answer: A
Rationale: The correct answer is A: Hydrocolloid. Hydrocolloid dressings are recommended for stage 2 pressure injuries as they help maintain a moist wound environment, which supports the healing process. Gauze (choice B) is not ideal for stage 2 pressure injuries as it can stick to the wound bed and disrupt the healing process. Transparent film dressings (choice C) are more suitable for superficial wounds or as a secondary dressing. Alginate dressings (choice D) are typically used for wounds with heavy exudate, which is not typically seen in stage 2 pressure injuries.
Question 2 of 5
A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?
Correct Answer: A
Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) Volume. In this case, it would be (800 units/hr / 25,000 units) 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.
Question 3 of 5
During an assessment, a healthcare professional is evaluating a client who has been on bed rest for the past month. Which of the following findings should the healthcare professional identify as an indication that the client has developed thrombophlebitis?
Correct Answer: C
Rationale: Calf swelling, redness, and tenderness are classic signs of thrombophlebitis. The swelling occurs due to the formation of a blood clot in the deep veins of the calf, leading to inflammation and potential obstruction of blood flow. Bladder distention (Choice A) is more indicative of urinary retention, decreased blood pressure (Choice B) can be seen in conditions like shock, and diminished bowel sounds (Choice D) may suggest gastrointestinal issues, none of which are directly related to thrombophlebitis.
Question 4 of 5
During a peripheral vascular assessment, a healthcare professional places the bell of the stethoscope on a client's neck and hears an audible vascular sound associated with turbulent blood flow. This sound indicates which of the following?
Correct Answer: A
Rationale: The correct answer is A: Narrowed arterial lumen. Arterial bruits are abnormal sounds caused by turbulent blood flow through narrowed or occluded arteries. This turbulent flow creates a blowing sound, which is heard as an arterial bruit. Distended jugular veins (choice B) are typically associated with venous issues, not arterial abnormalities. Impaired ventricular contraction (choice C) and asynchronous closure of the aortic and pulmonic valve (choice D) are not directly related to the audible vascular sound described in the scenario.
Question 5 of 5
While auscultating the anterior chest of a client newly admitted to a medical-surgical unit, a nurse listens to the audio clip of breath sounds through her stethoscope. What type of breath sounds does the nurse hear?
Correct Answer: D
Rationale: The correct answer is D: Normal breath sounds. In the scenario described, the nurse hears normal bronchovesicular breath sounds, which are moderate in intensity and resemble blowing as air moves through the larger airways during inspiration and expiration. Crackles (choice A) are typically heard in conditions like heart failure or pneumonia and are not present in this case. Rhonchi (choice B) are low-pitched, continuous sounds often associated with conditions like chronic bronchitis or bronchiectasis. Friction rub (choice C) is a grating sound usually heard in conditions like pleurisy or pericarditis, which is not the case here where normal breath sounds are heard.
