A charge nurse is discussing the phases of community response to disaster with nursing staff. Which of the following statements indicates an understanding of the heroic phase of disaster response?

The correct answer is: The nurse has reviewed the client’s medical record. The client is at risk for developing

Hypotension and Metabolic Acidosis

Choice A: Hyperkalemia

Hyperkalemia refers to an elevated level of potassium in the blood. The normal range for potassium is 3.5 to 5.0 mEq/L. In this case, the client’s potassium level is 5.0 mEq/L, which is at the upper limit of normal. While the client is not currently hyperkalemic, they are at risk due to their condition. However, hyperkalemia is not the most immediate concern based on the provided data. The client’s symptoms and diagnostic results point more directly to other conditions.

Choice B: Hypertension

Hypertension is high blood pressure. The client’s blood pressure is 96/68 mm Hg, which is below the normal range (typically around 120/80 mm Hg). This indicates hypotension rather than hypertension. Given the client’s history of hypertension, the current low blood pressure is concerning and suggests a different issue, such as dehydration or fluid loss from diarrhea.

Choice C: Hypokalemia

Hypokalemia is a condition where potassium levels are below normal. The client’s potassium level is 5.0 mEq/L, which is within the normal range. Therefore, hypokalemia is not a concern in this scenario. The client’s potassium level does not indicate a risk for hypokalemia, and their symptoms do not align with this condition.

Choice D: Hypernatremia

Hypernatremia is an elevated sodium level in the blood. The normal range for sodium is 136 to 145 mEq/L. The client’s sodium level is 149 mEq/L, which is above the normal range, indicating hypernatremia. This condition can result from dehydration, which is consistent with the client’s symptoms of diarrhea and poor skin turgor. However, while hypernatremia is a concern, it is not the most critical issue compared to hypotension and metabolic acidosis.

Choice E: Hypotension

Hypotension is low blood pressure. The client’s blood pressure is 96/68 mm Hg, which is below the normal range. This low blood pressure, combined with symptoms of weakness, dizziness, and poor skin turgor, suggests significant fluid loss and dehydration. Hypotension is a critical concern as it can lead to inadequate perfusion of organs and tissues, potentially causing further complications.

Choice F: Renal Failure

Renal failure refers to the kidneys’ inability to filter waste from the blood effectively. While the client’s urine output is low (30 mL/hr), which could indicate renal impairment, there is no direct evidence from the provided data to confirm renal failure. The client’s basic metabolic profile does not show elevated creatinine or BUN levels, which are typical indicators of renal function.

Choice G: Metabolic Acidosis

Metabolic acidosis is a condition where there is too much acid in the body fluids. The normal range for blood pH is 7.35 to 7.45. The client’s pH is 7.33, which is below the normal range, indicating acidosis. Additionally, the bicarbonate (HCO3) level is 19 mEq/L, which is below the normal range of 21 to 28 mEq/L. These findings confirm metabolic acidosis, likely due to the loss of bicarbonate through diarrhea.

Choice A reason:

Measuring a client’s intake and output (I&O) is a task that can be performed by assistive personnel (AP). This task involves recording the amount of fluids a client consumes and excretes, which does not require the specialized skills of an LPN. Therefore, it is more appropriate to assign this task to the AP.

Choice B reason:

Obtaining a client’s weight is another task that can be delegated to assistive personnel (AP). This task involves using a scale to measure the client’s weight and recording the result. It is a routine task that does not require the advanced training of an LPN.

Choice C reason:

Providing postmortem care for a client can be performed by assistive personnel (AP) under the supervision of an RN or LPN. This task involves preparing the body after death, which includes cleaning and positioning the body. While LPNs can perform this task, it is not exclusive to their scope of practice and can be delegated to AP.

Choice D reason:

Inserting a nasogastric tube for a client is a task that requires the specialized skills and training of an LPN. This procedure involves inserting a tube through the client’s nose into the stomach, which requires knowledge of anatomy, sterile technique, and the ability to assess for complications. Therefore, this task should be assigned to the LPN.
