You are responsible for reviewing the nursing unit's refrigerator. Which of the following drugs, if found inside the fridge, should be removed?
- A. Nadolol (Corgard)
- B. Opened (in-use) Humulin N injection
- C. Urokinase (Kinlytic)
- D. Epoetin alfa IV (Epogen)
Correct Answer: A
Rationale: Nadolol (Corgard) should be removed if found inside the fridge because it is supposed to be stored at room temperature between 59 to 86 ºF (15 and 30 ºC) away from heat, moisture, and light. Storing it in the refrigerator can alter its effectiveness and stability.
Option B, the opened Humulin N injection, should not be stored in the refrigerator as it is an in-use product and can remain at room temperature for a certain period as per manufacturer guidelines. Option C, Urokinase (Kinlytic), and Option D, Epoetin alfa IV (Epogen), do not require refrigeration and can be stored at room temperature. Therefore, Nadolol (Corgard) is the drug that should be removed from the fridge.

What preparation should be made for a client undergoing a KUB (Kidney, Ureter, Bladder) radiography test?
- A. Client must be NPO before the examination
- B. Enema should be administered before the examination
- C. Medicate the client with furosemide 20 mg IV 30 minutes before the examination
- D. No special orders are necessary for this examination
Correct Answer: D
Rationale: The correct answer is that no special orders are necessary for a KUB radiography test. It is important to inform the client to remove any clothing, jewelry, or objects that may interfere with the test. Option A is incorrect because there is no need for the client to be NPO before this examination. Option B is incorrect as enemas are not routinely administered prior to a KUB radiography test. Option C is incorrect as there is no need to medicate the client with furosemide before this examination.
The nurse is caring for a 27-year-old female client with a venous stasis ulcer. Which nursing intervention would be most effective in promoting healing?
- A. Apply dressing using sterile technique
- B. Improve the client's nutrition status
- C. Initiate limb compression therapy
- D. Begin proteolytic debridement
Correct Answer: B
Rationale: Venous stasis occurs when venous blood collects and stagnates in the lower leg due to incompetent venous valves. This leads to inadequate oxygen and nutrient supply to the cells in the lower extremities, resulting in cell death or necrosis. Venous stasis ulcers, characterized by shallow brown wounds with irregular margins, typically develop on the lower leg or ankle. The primary goal in managing clients with venous stasis ulcers is to promote healing. Proper nutrition plays a crucial role in wound healing. Nutritional deficiencies are common causes of venous ulcers, and a diet rich in protein, iron, zinc, and vitamins C and A is recommended to enhance wound healing. Applying dressings with sterile technique, initiating limb compression therapy, and beginning proteolytic debridement are important interventions in wound care but may not directly address the underlying issue of poor nutrition that is essential for healing venous stasis ulcers.
A healthcare professional is reviewing a patient's chart and notices that the patient suffers from conjunctivitis. Which of the following microorganisms is related to this condition?
- A. Yersinia pestis
- B. Helicobacter pylori
- C. Vibrio cholerae
- D. Haemophilus aegyptius
Correct Answer: D
Rationale: The correct answer is Haemophilus aegyptius. Haemophilus influenzae biogroup aegyptius (Hae) is a causative agent of acute and often purulent conjunctivitis, more commonly known as pink eye. Yersinia pestis, Helicobacter pylori, and Vibrio cholerae are not associated with conjunctivitis. Yersinia pestis causes the plague, Helicobacter pylori is associated with gastric ulcers, and Vibrio cholerae causes cholera.
The client is being prepared for insertion of a pulmonary artery catheter (Swan-Ganz catheter). What information does the client need to know about the purpose of this catheter insertion?
- A. Stroke volume
- B. Cardiac output
- C. Venous pressure
- D. Left ventricular functioning
Correct Answer: D
Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.
A client with a new colostomy is being taught how to care for the colostomy bag. Which statement from the client indicates the need for more education?
- A. I can clean the skin around the ostomy site with soap and water when I change the bag.
- B. I should irrigate the stoma regularly to avoid buildup of gas and odor.
- C. I need to wait 30 minutes after I irrigate to replace the colostomy bag.
- D. I should change the bag when it is one-third to one-fourth full.
Correct Answer: C
Rationale: A client with a new colostomy requires education on proper colostomy care. Waiting 30 minutes after irrigating to replace the colostomy bag is unnecessary. The client may reapply the bag once the skin is dry. Cleaning the skin around the ostomy site with soap and water, irrigating the stoma regularly to prevent gas and odor buildup, and changing the bag when it is one-third to one-fourth full are appropriate actions. Therefore, the statement indicating the need for more education is the one suggesting a specific time interval for bag replacement after irrigation.
