Correct Answer: A

Rationale: The correct answer is A: Monitor gastric residual volume and check for abdominal distension. These assessments are critical to evaluate the patient's tolerance to enteral feeding. Monitoring gastric residual volume helps determine gastric emptying, while checking for abdominal distension can identify complications like bowel obstruction. Choices B, C, and D are important aspects of enteral feeding care but are not the primary assessments. Ensuring the correct placement of the feeding tube is crucial for safety, assessing for signs of dehydration and electrolyte imbalances is essential for overall patient well-being, and elevating the head of the bed is vital to prevent aspiration. However, these are not the key assessments specifically related to enteral feeding.

Correct Answer: A

Rationale: The correct nursing interventions for a patient with neutropenia include monitoring for signs of infection and administering antibiotics. Neutropenia is characterized by a low neutrophil count, which increases the risk of infections. Monitoring for signs of infection allows for early detection and prompt treatment, while administering antibiotics helps prevent or treat any infections that may occur. Isolating the patient and providing a low-microbial diet (Choice B) are not necessary unless the patient develops an active infection. Monitoring vital signs and avoiding unnecessary invasive procedures (Choice C) are important but do not specifically address the increased infection risk in neutropenic patients. Encouraging the patient to engage in social activities (Choice D) is not appropriate for a neutropenic patient due to the risk of exposure to infectious agents.

Correct Answer: B

Rationale: The correct position for a lumbar puncture is the lateral recumbent position. This position allows the spine to curve naturally, widening the spaces between the vertebrae, making it easier and safer to perform the procedure. Supine with head elevated (Choice A) would not provide the proper positioning for a lumbar puncture as it does not allow for proper access to the lumbar area. Prone with arms at sides (Choice C) would not be suitable as it would not facilitate the procedure. Sitting with back rounded (Choice D) is also incorrect as it does not allow for the proper alignment of the spine needed for a lumbar puncture.

Correct Answer: B

Rationale: When a client develops redness and warmth at the IV site, it is indicative of phlebitis, which is inflammation of the vein. The next step for the nurse should be to discontinue the IV and notify the healthcare provider. Applying a cold compress may provide temporary relief but does not address the underlying issue. Monitoring for infection is important, but in this case, the presence of redness and warmth suggests phlebitis, not infection. Increasing the IV flow rate can exacerbate the inflammation and should be avoided.

Correct Answer: B

Rationale: Restlessness and agitation in clients with dementia should be addressed immediately as they can indicate underlying causes such as pain, discomfort, or unmet needs. Addressing these symptoms promptly can help prevent the escalation of behavioral issues and improve the client's quality of life. While frequent episodes of wandering at night, mild confusion during the day, and incontinence are also important issues to address in clients with dementia, restlessness and agitation usually require immediate attention to ensure the safety and well-being of the client.
