A nurse is assessing a client 15 minutes after administering morphine sulfate 2 mg via IV push. The nurse should identify which of the following findings as an adverse effect of the medication?

Choice A reason: Palpate the client’s pedal pulses

Palpating the client’s pedal pulses assesses the blood flow to the lower extremities but does not provide information about the client’s muscle strength. This action is important for evaluating circulation but is not relevant for determining strength.

Choice B reason: Ask the client how strong she feels today

Asking the client how strong she feels today provides subjective information about the client’s perception of her strength. While this can be useful, it does not offer an objective measure of muscle strength. Objective assessments are more reliable for determining the client’s actual strength.

Choice C reason: Ask the client to touch her finger to her nose

Asking the client to touch her finger to her nose assesses coordination and fine motor skills rather than muscle strength. This test is often used to evaluate neurological function but does not provide information about the strength of the muscles needed for ambulation.

Choice D reason: Ask the client to push her feet against the nurse’s palms

Asking the client to push her feet against the nurse’s palms is an effective way to assess the strength of the lower extremities. This action provides an objective measure of the client’s muscle strength, which is crucial for determining her ability to ambulate safely. This test helps the nurse evaluate whether the client has sufficient strength to stand and walk.

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.
