Correct Answer: D

Rationale: In this scenario, the most important intervention for a male client with schizophrenia who is diaphoretic and pacing the hallway is to carefully observe the client throughout the shift. Diaphoresis and pacing can be indicators of agitation or distress in clients with schizophrenia. Careful observation is crucial to monitor the client's safety, assess for any potential escalation of symptoms, and provide timely intervention if needed. Taking the client's temperature and blood pressure (Choice A) may not address the immediate need for safety and observation. Encouraging the client to rest (Choice B) may not be effective if the client is agitated. Planning an activity involving physical exercise (Choice C) could potentially exacerbate the situation rather than addressing the immediate need for observation and safety.

Correct Answer: C

Rationale: The correct answer is C: 'Decreased edema and improved peripheral pulses.' In a client with heart failure, furosemide is a diuretic that helps reduce fluid overload. Therefore, a decrease in edema (swelling due to fluid retention) and improved peripheral pulses (indicating better circulation) are signs that the medication is effective. Choices A, B, and D are incorrect. Increased urine output and weight loss (Choice A) may indicate the diuretic effect of furosemide but do not specifically reflect its effectiveness in heart failure. Increased heart rate and blood pressure (Choice B) are not desired effects of furosemide and may suggest adverse reactions. Decreased shortness of breath and clear lung sounds (Choice D) are related to improved respiratory status and may not directly reflect the effectiveness of furosemide in addressing fluid overload.

Correct Answer: B

Rationale: Using an abduction pillow between the client's legs is the most appropriate nursing action to prevent dislocation after hip replacement surgery. An abduction pillow helps maintain proper alignment and prevents the hip from dislocating. Placing the client in a high Fowler's position (Choice A) or encouraging them to sit upright for long periods (Choice D) may not provide the necessary support and stability needed to prevent hip dislocation. Encouraging the client to cross their legs while sitting (Choice C) can increase the risk of hip dislocation and should be avoided.

Correct Answer: A

Rationale: The nurse's signature on a surgical consent form signifies that the client voluntarily grants permission for the procedure to be done. This is the correct answer because the nurse's signature does not imply the client's competence, understanding of risks and benefits, or that the client signed the form freely and voluntarily. The nurse's role is to verify that the client has made an informed decision and is providing consent for the procedure.

Correct Answer: B

Rationale: The correct teaching for a client with lupus erythematosus prescribed prednisone is to avoid crowded places to reduce the risk of infection. Prednisone suppresses the immune system, making individuals more susceptible to infections. Taking the medication with food may help reduce stomach upset but is not the priority teaching. Taking prednisone in the morning may help reduce insomnia, but infection prevention is more critical. While prednisone can lead to osteoporosis, advising extra calcium supplements is not the most immediate concern when starting the medication.
