Correct Answer: D

Rationale: Fever in a client with rheumatoid arthritis can indicate an underlying infection or a more serious systemic involvement, such as vasculitis or inflammation of internal organs. These conditions can lead to serious complications and require immediate medical attention. Joint deformities and morning stiffness are common manifestations of rheumatoid arthritis itself and may not be indicative of an acute issue. Weight loss can be seen in chronic inflammatory conditions like rheumatoid arthritis but is not as concerning as fever, which suggests an acute process requiring prompt evaluation and intervention.

Correct Answer: B

Rationale: The correct answer is B, which is low-molecular-weight heparin doses. After hip replacement surgery, patients are at risk of developing deep vein thrombosis (DVT) due to immobility. Heparin and low-molecular-weight heparin are commonly used for prophylaxis against DVT. Monitoring for hemorrhage is crucial when administering anticoagulants. Choices A, C, and D are not directly related to monitoring for hemorrhage in this scenario. Thick, tenacious pulmonary secretions (Choice A) may indicate respiratory issues, SCDs (Choice C) help prevent DVT but do not directly relate to hemorrhage monitoring, and elastic stockings (TED hose) (Choice D) are used for DVT prophylaxis but do not alert to hemorrhage.

Correct Answer: C

Rationale: The Romberg test is a neurological test that assesses proprioception and balance. To perform this test, the client is asked to stand with their feet together and arms at their sides while closing their eyes. By removing visual input, the test challenges the vestibular and proprioceptive systems. Choices A, B, and D are incorrect because they do not align with the proper procedure for conducting the Romberg test. Extending arms in front, walking heel to toe, or placing hands on hips are not part of the Romberg test protocol and may introduce variables that could affect the assessment of balance.

Correct Answer: A

Rationale: When a client is receiving 100% oxygen via a partial rebreathing mask, there is a higher risk for oxygen toxicity due to the higher concentration of oxygen delivered. This client should be assessed most frequently for manifestations of oxygen toxicity. Choices B, C, and D are less likely to result in oxygen toxicity compared to 100% oxygen delivery via a partial rebreathing mask.

Correct Answer: B

Rationale: The correct response is 'It is very upsetting to see an adult client regress.' In this situation, the nurse should acknowledge the emotional impact of caregiving on the assistive personnel and address it professionally. Choice A is incorrect because reporting to the supervisor may not directly address the emotional concerns raised. Choice C is incorrect because immediately resorting to diapers without further assessment or intervention is not the most appropriate solution. Choice D is incorrect as the client's well-being and care are a shared responsibility among healthcare team members.
