The nurse inserts a urinary catheter and obtains a scant amount of dark amber output. Which intervention should the nurse implement first? (Please scroll and view each tab's information in the client's medical record before selecting the answer.)
Initiate continuous dopamine infusion at 2 mcg/kg/minute.
Administer promethazine 25 mg slow intravenous (IV) push every 4 hours.
Begin potassium chloride 10 mEq over 1 hour per secondary infusion.
Give a bolus of 0.9% sodium chloride 1,000 ml over 30 minutes.
The Correct Answer is D
A) Incorrect - Initiating continuous dopamine infusion is not a priority in this situation. The client's low blood pressure and electrolyte imbalances require more immediate attention.
B) Incorrect - Administering promethazine addresses symptoms like nausea and vomiting, but it doesn't address the primary issue of hypovolemia and low blood pressure.
C) Incorrect - Administering potassium chloride without addressing the fluid deficit can be dangerous and may lead to further electrolyte imbalances.
D) Correct- The client's vital signs and laboratory results indicate hypovolemia (low blood pressure, low sodium, and low potassium). The immediate priority is to address the fluid deficit and correct the electrolyte imbalances. Administering a bolus of 0.9% sodium chloride (normal saline) will help increase intravascular volume and improve blood pressure, as well as correct the electrolyte imbalances to some extent.

Correct Answer is A
Explanation
A) Correct- As a nurse, it's important to provide accurate and helpful information to patients and families. In this situation, the parents have brought literature from a genetic counselor and are seeking clarification. The nurse should review the literature to the best of their ability and answer any questions they can. This approach demonstrates support, a willingness to help, and a commitment to providing accurate information.
B) Incorrect- While understanding the parents' reasons for seeking genetic counseling is important, it shouldn't be the first response when they have already brought literature and are seeking clarification. Addressing their questions and concerns is the immediate priority.
C) Incorrect- While it's true that the couple could contact the genetic counselor for further information, as a healthcare professional, the nurse should still offer assistance by reviewing the literature and answering questions to the best of their ability.
D) Incorrect- While support groups can be beneficial for parents of children with Trisomy 21, the immediate concern is addressing the parents' questions about the literature they've brought. Providing accurate information should be the primary focus at this time.
Correct Answer is A
Explanation
A) Correct- Zidovudine is an antiretroviral medication used in the treatment of HIV infection.
One of the potential side effects of zidovudine is hematological toxicity, including anemia (low red blood cell count) and neutropenia (low white blood cell count). The appearance of pinpoint, red, round spots on the skin could be indicative of petechiae, which are small hemorrhages caused by the leakage of blood into the skin. Petechiae can occur due to low platelet counts, a
component of the complete blood count (CBC). Monitoring the complete blood count is important for clients receiving zidovudine to identify any potential adverse effects on blood cell counts. Anemia and neutropenia can increase the risk of infection, bleeding, and other complications. Therefore, any changes in blood cell counts, including the presence of petechiae, should be reported to the healthcare provider for further evaluation and management.
B) Incorrect- This is used to assess allergic reactions and is not specifically related to the appearance of petechiae.
C) Incorrect- A skin biopsy is typically performed to diagnose skin conditions or diseases and is not the primary assessment to evaluate the cause of petechiae.
D) Incorrect- Electromyography is a diagnostic test used to assess muscle and nerve function and is not relevant to the appearance of petechiae associated with zidovudine use.
