In the operating room, personnel should be responsible for ensuring cleanliness, proper temperature, humidity, and lighting. Who carries those responsibilities?

Correct Answer: A

Rationale: The circulating nurse is responsible for ensuring the cleanliness, proper temperature, humidity, and lighting in the operating room. The circulating nurse plays a crucial role in maintaining the overall environment and ensuring that it meets the necessary standards for the safety and well-being of the patient and the surgical team. They are in charge of coordinating and overseeing all aspects of the operating room environment, including maintaining a sterile field, assisting with instrument setup, and ensuring that all equipment is functioning properly. Additionally, the circulating nurse manages communication within the operating room and ensures that all necessary supplies are available during the surgical procedure. It is within the circulating nurse's scope of practice to take charge of these responsibilities to create an optimal operating room environment.

Correct Answer: C

Rationale: Diabetes insipidus is a condition characterized by excessive thirst and excretion of large amounts of dilute urine, resulting in fluid volume deficit. The posterior pituitary tumor in this case is likely causing decreased secretion of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine and retain water. This imbalance results in the loss of fluid, leading to dehydration and electrolyte imbalances. Therefore, the most appropriate nursing diagnosis for this client is fluid volume deficit, as the priority is to address the dehydration and restore fluid balance to prevent further complications.

Correct Answer: A

Rationale: Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. If a client with SIADH does not comply with the recommended treatment of diuretic therapy and fluid/sodium restriction, there will be continued water retention, resulting in further dilution of sodium levels in the blood (hyponatremia). Severe hyponatremia can lead to cerebral edema, which is a life-threatening complication associated with neurological symptoms such as headache, confusion, seizures, and potentially coma. Therefore, it is important for the client to follow the prescribed treatment to prevent the development of cerebral edema and other serious complications.

Correct Answer: C

Rationale: Regular follow-up care is crucial after a thyroidectomy for Grave's disease to monitor the patient's thyroid hormone levels, assess for signs of complications such as hypothyroidism or hypoparathyroidism, and ensure appropriate management of any related conditions. Routine follow-up visits with healthcare providers allow for ongoing assessment and adjustment of medications, as well as addressing any concerns the patient may have post-surgery. By emphasizing the importance of regular follow-up care, the healthcare team can provide necessary support and guidance to the patient throughout their recovery process.

Correct Answer: A

Rationale: Hypoglycemia is defined as a blood glucose level below 70mg/dl. When a client is experiencing hypoglycemia, it means their blood sugar is lower than the normal range and can lead to symptoms such as sweating, tremors, confusion, and even loss of consciousness. It is important for nurses to recognize and treat hypoglycemia promptly to prevent serious complications.
