A client is currently receiving an infusion labeled Heparin Sodium 25,000 Units in 5% Dextrose Injection 500 mL at 14 ml/hour. A prescription is received to change the rate of the Infusion to 900 units of heparin per hour. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["18"]

First, we need to find the concentration of Heparin per milliliter in the current infusion. We can do this by dividing the total number of Heparin units by the total volume of the infusion:

Heparin concentration (units/mL) = Total Heparin units / Total volume (mL) Heparin concentration = 25,000 units / 500 mL

Heparin concentration = 50 units/mL

Now, we know the desired rate of Heparin delivery (900 units/hour) and the concentration of Heparin per milliliter (50 units/mL). We can use this information to calculate the required flow rate in milliliters per hour:

Flow rate (mL/hour) = Desired Heparin rate (units/hour) / Heparin concentration (units/mL)

Flow rate = 900 units/hour / 50 units/mL Flow rate = 18 mL/hour

Therefore, the nurse should set the infusion pump to deliver 18 mL/hour.

Correct Answer is C

Explanation

A. Maintaining nasal packing may be important post-hypophysectomy to prevent bleeding or cerebrospinal fluid leaks. However, in the context of Cushing's disease, ensuring oral hygiene is
paramount due to increased risk of infection, especially if the patient is on corticosteroid therapy, which suppresses the immune system.

B. Keeping the head of the bed at 30° helps prevent complications such as cerebral edema and increased intracranial pressure. While this is important post-hypophysectomy, it's not specific to Cushing's disease or a priority over oral care.

C. Providing frequent mouth care is crucial in Cushing's disease due to increased cortisol levels leading to immunosuppression and susceptibility to infections. Additionally, glucocorticoid therapy can cause mucosal dryness and ulceration, necessitating meticulous oral hygiene.

D. Monitoring intake and output is essential postoperatively to assess fluid balance and renal function. While important, it's not the priority in this context compared to oral care, especially considering the risk of dehydration due to increased cortisol levels in Cushing's disease.

A. Begin parenteral antibiotic therapy. B. Administer antiemetic agents. C. Provide a high-calorie, high-protein diet. D. Bivalve the cast for distal compromise.

Correct Answer is A

Explanation

A. Begin parenteral antibiotic therapy.
This is the correct answer. Osteomyelitis is a serious bone infection that requires prompt and aggressive antibiotic therapy to prevent further complications and promote healing.

B. Administer antiemetic agents.
Antiemetic agents may be necessary if the client is experiencing nausea or vomiting, but this is not the priority action.

C. Provide a high-calorie, high-protein diet.
While nutritional support is important for healing, initiating antibiotic therapy to address the infection takes precedence.

D. Bivalve the cast for distal compromise.
Bivalving the cast might be necessary if there is evidence of compartment syndrome or impaired circulation, but there is no indication from the question that such a complication is present at this time.
