Mrs. Kalen is a 70-year-old female who has arrived at the ER due to persistent vomiting for two days now. She appears to be lethargic and weak and has myalgia. She is noted to have dry mucus membranes and her capillary refill takes >4 seconds. She is diagnosed as having gastroenteritis and dehydration. Measurement of arterial blood gas shows pH 7.5, PaO2 85 mm Hg, PaCO2 40 mm Hg, and HCO3 34 mmol/L. Based on the acid-base interruption from Mrs. Kalen, what can the nurse anticipate the treatment will be for correcting this imbalance?
administration of antiemetics
administration of diuretics
Possible Electrolyte replacement if warranted
Administration of IV 0.9 Saline Solution infusion
Have the patient go home and rest. It will resolve itself shortly.
The Correct Answer is D
Mrs. Kalen is diagnosed with gastroenteritis and dehydration, and the arterial blood gas results indicate metabolic alkalosis (elevated pH and HCO3-). This suggests that there is an excessive loss of gastric acid and chloride ions from vomiting, leading to an imbalance of electrolytes and an increase in bicarbonate levels.
To correct the imbalance and treat dehydration, the primary intervention is fluid replacement. Administration of IV 0.9 Saline Solution, also known as normal saline, is commonly used for fluid resuscitation and rehydration. This isotonic solution helps restore fluid balance and electrolyte levels in the body.
Administration of antiemetics may help control vomiting, but the primary treatment focus in this case is fluid and electrolyte replacement to correct dehydration and the associated metabolic alkalosis.
Administration of diuretics, which increase urine output, would not be appropriate in this case as the patient is already experiencing dehydration.
Electrolyte replacement may be necessary if there are specific electrolyte imbalances identified, but the primary treatment is fluid replacement with IV saline solution.
Having the patient go home and rest without addressing the underlying dehydration and metabolic alkalosis would not be appropriate as it can lead to further complications.

Explanation
Muscle rigidity is a hallmark sign of malignant hyperthermia. It commonly affects the muscles of the jaw and upper chest.
Malignant hyperthermia can lead to rapid and shallow breathing, resulting in tachypnea. Malignant hyperthermia is characterized by a significant increase in body temperature, often exceeding 38.8°C (101.8°F).
Malignant hyperthermia can cause irregular heart rhythms or dysrhythmias, including tachycardia or arrhythmias.
The manifestations of hypertension and skin mottling are not typically associated with malignant hyperthermia. Hypertension (high blood pressure) is more commonly seen in conditions such as hypertensive emergencies or certain cardiovascular disorders. Skin mottling, which refers to irregular or patchy skin coloration, is not a specific manifestation of malignant hyperthermia.

Explanation
Ensure the client receives adequate amounts of fluids: This is important to maintain hydration and thin respiratory secretions, making it easier for the client to cough and clear the airways. Check the client's mouth for stomatitis: Methylprednisolone can increase the risk of developing oral candidiasis (thrush) or stomatitis, which can cause discomfort and interfere with oral intake. Regular mouth checks can help identify these conditions early for appropriate management. Assess the client's mental status: Pneumonia, particularly in individuals with pre-existing lung disease like COPD, can lead to hypoxemia, which may affect mental status. It is important to monitor the client's mental status, as changes in cognition or confusion can be indicators of hypoxia and require prompt intervention.
Monitor for signs of hypokalemia: Methylprednisolone, like other corticosteroids, can cause electrolyte imbalances, including hypokalemia (low potassium levels). Hypokalemia can have various effects on the body, including muscle weakness and cardiac dysrhythmias. Regular monitoring of potassium levels and signs of hypokalemia is important for timely management. Monitor the client's blood glucose levels: Methylprednisolone can increase blood glucose levels, particularly in individuals with pre-existing diabetes or impaired glucose tolerance. Regular monitoring of blood glucose levels is necessary to ensure proper glycemic control and prevent hyperglycemia-related complications.
Monitor the client's blood pressure for hypotension: Corticosteroids like methylprednisolone can cause fluid retention, leading to an increase in blood pressure. However, sudden withdrawal of corticosteroids can result in adrenal insufficiency and hypotension. Close monitoring of blood pressure is necessary to identify any significant changes and adjust the medication regimen accordingly.
