Correct Answer: A

Rationale: The correct answer is A because the LPN can care for stable clients with complex needs, such as managing an NGT set to continuous suction. Choices B, C, and D involve clients with more acute conditions that require a higher level of assessment and intervention, making them unsuitable for delegation to an LPN. Choice B requires prompt evaluation of the shortness of breath in a client with a recent femur fracture, which is beyond the LPN's scope. Choice C involves a head injury and unequal pupils, indicating the need for neurological assessment and close monitoring. Choice D relates to a critically low hemoglobin level and the need for blood transfusion, requiring careful monitoring and potential intervention beyond the LPN's role.

Correct Answer: B

Rationale: The correct manifestation to expect when collecting data from a client with PTSD is hypervigilance. Hypervigilance refers to increased alertness, which is a common symptom of PTSD. This heightened state of awareness is characterized by an exaggerated startle response, being easily startled, and constantly scanning the environment for potential threats. Amnesia (choice A) is not typically a primary manifestation of PTSD; it is more commonly associated with dissociative disorders. Hallucinations (choice C) involve perceiving things that are not present and are not typically a hallmark symptom of PTSD. Severe agitation (choice D) may occur in individuals with PTSD, but hypervigilance is a more specific and common manifestation associated with this disorder.

Correct Answer: A

Rationale: The correct answer is A: Maintain sterility during dressing changes. It is crucial to maintain sterility during dressing changes for patients with central venous catheters to prevent infections. Changing the dressing weekly (Choice B) is not frequent enough to prevent infections effectively. Monitoring blood pressure and fluid balance (Choice C) is important for overall patient care but not specific to central venous catheter management. While monitoring the catheter site for infection (Choice D) is important, the key consideration is to prevent infections through proper sterile techniques during dressing changes.

Correct Answer: A

Rationale: The correct answer is a low-protein diet for a patient with chronic kidney disease. In chronic kidney disease, the kidneys may have difficulty filtering waste products from protein metabolism, leading to a buildup of toxins in the body. Therefore, reducing protein intake can help lessen the workload on the kidneys. Choices B, C, and D are incorrect. A high-protein diet would increase the workload on the kidneys, while a low-sodium diet is beneficial for conditions like hypertension or heart failure but not specifically targeted for chronic kidney disease. A high-sodium diet can worsen fluid retention and hypertension in patients with kidney disease.

Correct Answer: B

Rationale: Using a bed exit alarm is the best intervention to prevent injury in a client with dementia at risk of falling. This device alerts staff when the client attempts to leave the bed, allowing for timely assistance and reducing the risk of falls. Placing the client in a room close to the nurses' station may help with supervision but does not provide immediate alerts like a bed exit alarm. Encouraging family members to stay with the client at all times may not be feasible, and raising all four side rails can lead to restraint issues and is not recommended unless necessary for the client's safety.
