1. Before administering an antibiotic that can cause nephrotoxicity, which lab value is most important for the PN to review?

Correct answer: C

Rationale: Serum creatinine is the most important lab value to review before administering an antibiotic that can cause nephrotoxicity. This is because serum creatinine is a key indicator of kidney function. An elevated serum creatinine level may indicate impaired renal function, and administering nephrotoxic drugs in such situations can further damage the kidneys. Monitoring serum creatinine levels helps healthcare providers assess renal function and make informed decisions regarding drug administration. Choices A, B, and D are not as directly related to kidney function and nephrotoxicity, making them less crucial in this scenario. Hemoglobin and hematocrit levels assess for anemia, serum calcium levels are more related to bone health and nerve function, and WBC count is associated with immune response, none of which directly reflect kidney function or the risk of nephrotoxicity.

2. When caring for a patient with a chest tube, which nursing action is most important?

Correct answer: B

Rationale: The most crucial nursing action when caring for a patient with a chest tube is to keep the drainage system below chest level (choice B). This position helps ensure proper drainage and prevents backflow of fluid or air into the pleural space, promoting optimal functioning of the chest tube. Clamping the chest tube every 2 hours (choice A) is incorrect as it can obstruct the drainage system and lead to complications. Emptying the drainage system every hour (choice C) is unnecessary unless there are specific clinical indications. Removing the chest tube when drainage decreases significantly (choice D) is also incorrect as the decision should be based on overall clinical assessment rather than drainage amount alone.

3. The PN assigns a UAP to assist with the personal care of a client experiencing an acute exacerbation of multiple sclerosis. Which instruction should the PN provide the UAP?

Correct answer: B

Rationale: During an acute exacerbation of multiple sclerosis, it is important to encourage self-care to maintain the client's independence. Allowing rest periods helps prevent fatigue, which is crucial in managing MS exacerbations. Choice A is incorrect as hot baths can exacerbate symptoms in MS. Choice C is about communication techniques and not directly related to client care during an exacerbation. Choice D is not a priority intervention during an MS exacerbation.

4. A client presents to the office with complaints of swelling in the legs, chills, and shortness of breath. During auscultation of the chest, a heart murmur is heard. The client's blood culture reveals a microorganism in the blood. When a microorganism is found in the blood, this condition is called

Correct answer: A

Rationale: When a microorganism is found in the blood, this condition is called bacteremia, which refers to the presence of bacteria in the bloodstream, as indicated by a positive blood culture. If not appropriately treated, bacteremia can progress to septicemia, also known as sepsis. Sepsis is a severe and life-threatening response to an infection, characterized by systemic inflammation and organ dysfunction. Parasitic infections involve pathogens other than bacteria and are not directly related to the scenario described.

5. Which of the following factors increases the risk of developing a pressure ulcer?

Correct answer: C

Rationale: Immobility is a significant risk factor for pressure ulcers because it leads to prolonged pressure on specific areas of the body, reducing blood flow and leading to tissue breakdown. Choices A, B, and D are incorrect. A high-protein diet can actually aid in wound healing and tissue repair. Frequent repositioning helps relieve pressure on bony prominences, reducing the risk of pressure ulcers. Active range of motion exercises can improve circulation and prevent muscle atrophy, thereby reducing the risk of pressure ulcers.
