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.

Answer and Explanation

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 D

Explanation

The correct answer is choiced. Children usually resume their toileting behaviors when they leave the hospital.

Choice A rationale:

While it is true that hospitalization can be stressful for preschoolers, providing diapers may not be necessary. Regression in toileting is often temporary and related to the stress of the hospital environment.

Choice B rationale:

Initiating a retraining program immediately after returning home may not be necessary. Most children will naturally resume their previous toileting behaviors once they are back in a familiar and less stressful environment.

Choice C rationale:

Bringing a potty chair from home can be helpful in some cases, but it is not always practical or necessary. The child is likely to resume normal toileting behaviors once they are back in their usual environment.

Choice D rationale:

This is the correct answer because children often regress in their toileting behaviors due to the stress and unfamiliarity of the hospital environment.Once they return home, they typically resume their previous toileting habits.

A. Document in the client's record. B. Prepare the client for an echocardiogram. C. Notify the healthcare provider. D. Limit the client's fluids.

Correct Answer is A

Explanation

An S3 heart sound can be a normal finding during pregnancy due to increased blood volume and changes in cardiac output. It is known as a physiological S3 and is considered a benign finding in the absence of other concerning symptoms or signs.

In this case, there is no immediate need for intervention or concern regarding the S3 heart sound. It is not necessary to prepare the client for an echocardiogram or limit the client's fluids based solely on the presence of an S3 heart sound in the absence of other significant symptoms or complications.
