Correct Answer: B

Rationale: The correct answer is B: Related to impaired balance. The rationale for this is that a cerebellar brain tumor can affect the client's coordination and balance due to its location in the brain responsible for fine motor movements. Impaired balance increases the risk for falls and injuries. Visual field deficits (choice A) may contribute to the risk of injury but not as directly as impaired balance. Difficulty swallowing (choice C) and psychomotor seizures (choice D) are not directly related to the client's risk for injury due to a cerebellar brain tumor.

Correct Answer: B

Rationale: The correct answer is B: L4-L5. This is because the L4-L5 intervertebral disc segment experiences the highest amount of mechanical stress and mobility in the lumbar spine, making it more prone to herniation. Additionally, nerve roots at this level innervate the lower extremities, making it a common site for symptoms such as sciatica. Choices A, C, and D are incorrect because herniations at those levels are less common due to lower mechanical stress and mobility compared to L4-L5.

Correct Answer: C

Rationale: The correct answer is C: Collaborative problem. The nurse needs to revise the collaborative problem part of the diagnostic statement because impaired physical mobility related to tibial fracture is a nursing diagnosis, not a collaborative problem. A collaborative problem involves potential complications that require both nursing and medical interventions. In this case, impaired physical mobility is a nursing diagnosis that requires nursing interventions to address the patient's inability to ambulate. Choices A, B, and D are incorrect because they are all relevant components of a nursing diagnostic statement: A - Etiology identifies the cause of the nursing diagnosis, B - Nursing diagnosis states the health problem, and D - Defining characteristic provides evidence supporting the nursing diagnosis.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen therapy. This is the priority intervention because a high temperature and diaphoresis indicate potential respiratory distress. Oxygen therapy can help improve oxygenation and support respiratory function. Providing frequent linen changes (B) is important for hygiene but not the priority. Fluid intake (C) is essential but not as urgent as addressing respiratory distress. Maintaining complete bed rest (D) may be necessary but addressing oxygenation takes precedence in this case.

Correct Answer: C

Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons, muscles, or glands. Its structure allows for the rapid transmission of electrical signals. Rationale: 1. Dendrites receive signals and transmit them towards the cell body, so A is incorrect. 2. Neurolemma is the outermost layer of a Schwann cell, not a part of the neuron responsible for transmitting impulses, so B is incorrect. 3. The synapse is the junction between two neurons where communication occurs, not a part of the neuron transmitting impulses, so D is incorrect.
