A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion.

Available is dopamine hydrochloride in a solution of 800 mg in a 250 mL bag.

The client weighs 80 kg. The nurse should set the IV infusion to deliver how many mL/hr? (Round the answer to the nearest whole number.

Use a leading zero if it applies.)

Choice A rationale:

A heart rate of 140/min is not a specific indicator of desmopressin effectiveness in a child with diabetes insipidus. The effectiveness of desmopressin is primarily evaluated based on the reduction in excessive urination and thirst associated with the condition. Monitoring heart rate is essential in certain situations but is not a direct measure of desmopressin efficacy in managing diabetes insipidus.

Choice B rationale:

Cessation of nocturnal enuresis (bedwetting) is a significant indication that desmopressin, an antidiuretic hormone, is effective. One of the main symptoms of diabetes insipidus is excessive urination, including during the night, leading to bedwetting. When desmopressin effectively reduces urine production, patients often experience improvement in these symptoms, including the cessation of nocturnal enuresis.

Choice C rationale:

Capillary refill of 3 seconds is a measurement used to assess peripheral perfusion and circulatory status. While it is essential to monitor capillary refill in pediatric patients, especially in cases of dehydration or circulatory compromise, it is not a specific indicator of desmopressin effectiveness in managing diabetes insipidus. Capillary refill time is more relevant in the assessment of cardiovascular function and fluid status.

Choice D rationale:

The absence of hypoglycemic episodes is not a direct indicator of desmopressin effectiveness. Diabetes insipidus is unrelated to blood glucose levels, as it involves the dysregulation of water balance due to insufficient antidiuretic hormone. While it is essential to monitor blood glucose levels in patients with diabetes mellitus, it is not relevant to assessing the effectiveness of desmopressin in treating diabetes insipidus.

The correct answer is Choice a.

Choice a rationale: The nurse should obtain the specimen immediately upon the client waking up, as sputum from deep in the lungs is usually more easily collected at this time. Sputum collected upon waking up is more likely to contain secretions from the lower respiratory tract, providing a better sample for tuberculosis diagnosis. This timing maximizes the chance of detecting the bacteria.

Choice b rationale: Choice b is incorrect because the typical volume of sputum needed for testing is about 1 teaspoon (5 mL), not 15 to 20 mL. Collecting such a large volume could be challenging for the client and unnecessary for diagnostic purposes.

Choice c rationale: Choice c is incorrect because while gloves should be worn, they do not need to be sterile, just clean. The use of clean gloves is sufficient to prevent contamination during specimen collection, and sterile gloves are not required for this procedure.

Choice d rationale: Choice d is incorrect because it’s important to try to collect the specimen as soon as possible, not wait a full day. Delaying collection for a day could result in a missed opportunity to diagnose tuberculosis and initiate appropriate treatment promptly. Collecting the specimen promptly maximizes the accuracy of diagnostic testing and facilitates timely intervention for the client's health.
