Question 1 of 5
A nurse has been ordered to set up Buck's traction on a patient's lower extremity due to a femur fracture. Which of the following applies to Buck's traction?
Correct Answer: C
Rationale: The correct answer is that the line of pull is straight for Buck's traction. This type of traction is applied to maintain alignment and immobilization of fractures, typically involving the lower extremities. A straight line of pull helps to provide the necessary countertraction to keep the fractured bone in proper alignment. Choices A and D are incorrect because Buck's traction commonly uses a weight range between 5-10 lbs, and using a weight greater than 10 or 20 lbs would not be appropriate or safe. Choice B is incorrect as well since the line of pull for Buck's traction is straight, not upward at an angle.
Question 2 of 5
Metformin (Glucophage) is administered to clients with type II diabetes mellitus. Metformin is an example of:
Correct Answer: A
Rationale: Metformin is classified as an antihyperglycemic agent because it works by reducing hepatic glucose output and decreasing glucose absorption from the gut, thereby preventing hyperglycemia. Choice B, a hypoglycemic agent, is incorrect as hypoglycemic agents stimulate insulin production, which is not the mechanism of action of metformin. Choice C, an insulin analogue, is incorrect as metformin is not a type of insulin but a distinct medication. Choice D, a pancreatic alpha cell stimulant, is incorrect as metformin does not stimulate any pancreatic cells, but rather acts on the liver and gut to lower blood sugar levels.
Question 3 of 5
A patient has experienced a severe third-degree burn to the trunk in the last 36 hours. Which phase of burn management is the patient in?
Correct Answer: A
Rationale: The correct answer is A: Shock phase. The shock phase occurs within the first 24-48 hours of burn management. During this phase, the focus is on stabilization, fluid resuscitation, and monitoring for potential complications. Choice B, the Emergent phase, is incorrect as it refers to the initial phase of burn care immediately after the injury. Choice C, the Healing phase, occurs later in the treatment process when the wound starts to repair itself. Choice D, the Wound proliferation phase, is not a recognized phase in burn management.
Question 4 of 5
A 64-year-old Alzheimer's patient has exhibited excessive cognitive decline resulting in harmful behaviors. The physician orders restraints to be placed on the patient. Which of the following is the appropriate procedure?
Correct Answer: C
Rationale: In cases where restraints are considered necessary for a patient, it is crucial to communicate effectively with both the patient and their family about the reasons for this decision. This helps ensure that all parties involved understand the necessity of restraints and are informed about the potential risks and benefits. Option A, securing restraints to the bed rails on all extremities, is not appropriate as it does not involve proper communication or ethical considerations. Option B, notifying the physician that restraints have been placed properly, overlooks the importance of patient and family involvement in decision-making. Option D, positioning the head of the bed at a 45-degree angle, is unrelated to the use of restraints and does not address the situation at hand.
Question 5 of 5
When caring for a client with a possible diagnosis of placenta previa, which of the following admission procedures should the nurse omit?
Correct Answer: B
Rationale: The correct answer is 'enema.' Administering an enema to a client with placenta previa can dislodge the placenta, leading to an increased risk of bleeding and complications. It is crucial to avoid any interventions that may disrupt the placenta's positioning. Collecting urine and blood specimens are necessary for diagnostic purposes and monitoring, while a perineal shave is a routine procedure that does not pose a risk to the client with placenta previa.
