During surgery, the nurse makes the following observations about the patient:
- Pulse rises from 68 beats per minute to 110 beats per minute.
- Temperature increases from 36.5 C to 38.50
- Muscles appear rigid.
The circulating nurse anticipates preparation of:
Naloxone (Narcan)
Dantrolene (Dentrum)
Furosemide (Lasix)
Flumazenil (Romazicon)
Flumazenil (Romazicon)
The Correct Answer is B
The given observations suggest the occurrence of malignant hyperthermia (MH), a potentially life-threatening reaction to certain medications used during anesthesia. MH is characterized by an increase in heart rate (tachycardia), elevated body temperature (hyperthermia), and muscle rigidity. The primary treatment for MH is the administration of dantrolene, which is a skeletal muscle relaxant that helps to counteract the effects of the reaction.
Naloxone (Narcan) is an opioid receptor antagonist used to reverse the effects of opioid overdose or excessive opioid sedation.
Furosemide (Lasix) is a diuretic used to treat conditions such as edema and high blood pressure.
Flumazenil (Romazicon) is a benzodiazepine receptor antagonist used to reverse the effects of benzodiazepine overdose or excessive sedation.

Correct Answer is B
Explanation
In a child with acute appendicitis, it is common to observe an elevated white blood cell count (WBC) as a response to the infection or inflammation associated with the condition. The neutrophil count may be within the lower end of the normal range or slightly decreased, as it can be affected by the severity and duration of the appendicitis. The red blood cell count (RBC) appears to be within the normal range. The lactic acid level is normal, indicating no significant metabolic acidosis.
Correct Answer is B
Explanation
Acute adrenal insufficiency, also known as adrenal crisis, is characterized by low levels of adrenal hormones, particularly cortisol. One of the primary manifestations of adrenal insufficiency is electrolyte imbalance, specifically hyponatremia (low sodium) and hyperkalemia (high potassium). Inadequate cortisol levels can lead to impaired sodium reabsorption in the kidneys, resulting in sodium loss and low serum sodium levels.
When the patient receives appropriate therapies for acute adrenal insufficiency, such as administration of glucocorticoids (e.g., hydrocortisone), the cortisol levels begin to normalize. As a result, the impaired sodium reabsorption improves, leading to an increase in serum sodium levels.
