A nurse is preparing to administer mannitol 0.2 g/kg IV bolus over 5 min as a test dose to a client who has severe oliguria. The client weighs 198 lb. What is the amount in grams the nurse should administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale:

A random plasma glucose level of 176 mg/dL indicates high blood sugar at the time of the test. Random glucose levels are not ideal for assessing glycemic control as they can vary based on recent food intake and stressors.

Choice B rationale:

Triglyceride levels are not used to assess glycemic control. They measure the amount of triglycerides in the bloodstream and are related to lipid metabolism, not glucose control.

Choice C rationale:

HbA1c (glycated hemoglobin) is a long-term measure of blood glucose control. An HbA1c level of 6.8% indicates acceptable glycemic control in a person with diabetes. The normal range for HbA1c is typically less than 6.5%. This test reflects the average blood sugar level over the past 2-3 months, giving a better understanding of overall glucose control.

Choice D rationale:

Fasting blood glucose of 120 mg/dL is slightly elevated. While fasting blood glucose levels below 100 mg/dL are generally considered normal, levels between 100-125 mg/dL are considered prediabetic, and levels above 126 mg/dL on two separate occasions indicate diabetes. The result provided falls within the prediabetic range but does not indicate optimal glycemic control.

Administer high-dose antibiotic therapy.

Rationale:

• A. Initiate droplet isolation precautions is incorrect because cystic fibrosis is not transmitted by droplets, but by autosomal recessive inheritance.
• B. Keep the child on NPO status for 12 hr is incorrect because there is no indication for withholding oral intake in this child. The child needs adequate hydration and nutrition to prevent dehydration and malnutrition due to increased metabolic demands and mucus production.
• C. Maintain the child on bed rest for 24 hr is incorrect because bed rest can worsen the child's respiratory status by decreasing lung expansion and increasing mucus retention. The child needs to be encouraged to ambulate and participate in activities as tolerated to promote airway clearance and prevent atelectasis and infection.
• D. Administer high-dose antibiotic therapy is correct because the child has signs of a pulmonary infection, such as wheezing, productive cough, and thick sputum. Antibiotics are indicated to treat the infection and prevent complications such as pneumonia and bronchiectasis.
