A nurse is providing teaching to the parent of a newborn who has gastroesophageal reflux (GER). Which of the following instructions should the nurse include?

Choice A reason: The client's creatinine level of 1.0 mg/dL is within the normal range, but it does not indicate that the treatment for benign prostatic hyperplasia has been effective. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys and excreted in urine. It reflects the kidney function, not the prostate condition.

Choice B reason: The client's urine output of 35 mL/hr is below the normal range, which is 40 to 60 mL/hr. This indicates that the client may have dehydration, kidney impairment, or urinary retention, which are complications of benign prostatic hyperplasia. A low urine output does not indicate that the treatment has been effective.

Choice C reason: The client's stool color and consistency are not related to the treatment for benign prostatic hyperplasia. Stool characteristics depend on various factors, such as diet, medication, and bowel function. A soft, brown stool does not indicate that the treatment has been effective.

Choice D reason: The client's ability to urinate without straining is a sign that the treatment for benign prostatic hyperplasia has been effective. Benign prostatic hyperplasia is a condition in which the prostate gland enlarges and compresses the urethra, causing difficulty in urination. A treatment that reduces the size of the prostate or relaxes the bladder neck muscles can improve the urine flow and reduce the straining.

Choice A reason: Potassium 3.5 mEq/L is not a finding that indicates fluid volume deficit because it is within the normal range, which is 3.5 to 5.0 mEq/L. Potassium is an electrolyte that regulates nerve and muscle function, acid-base balance, and fluid balance. Potassium level can be affected by various factors, such as diet, medication, kidney function, and dehydration.

Choice B reason: Sodium 145 mEq/L is not a finding that indicates fluid volume deficit because it is within the normal range, which is 136 to 145 mEq/L. Sodium is an electrolyte that regulates blood pressure, blood volume, and fluid balance. Sodium level can be affected by various factors, such as diet, medication, kidney function, and fluid loss.

Choice C reason: Hematocrit 53% is a finding that indicates fluid volume deficit because it is above the normal range, which is 38 to 50% for men and 34 to 46% for women. Hematocrit is the percentage of red blood cells in the total blood volume. Hematocrit level can increase due to dehydration, which causes hemoconcentration or increased blood viscosity.

Choice D reason: HbA1c 5% is not a finding that indicates fluid volume deficit because it is within the normal range, which is less than 5.7%. HbA1c is the percentage of hemoglobin that is attached to glucose. HbA1c level reflects the average blood glucose level over the past two to three months. HbA1c level can be affected by various factors, such as diabetes, anemia, and medication.
