A nurse cares for a patient who has a serum potassium of 7.5 mEq/L and is exhibiting cardiovascular changes. Which should the nurse implement first?

Provide a heart healthy low potassium diet

Prepare to administer sodium polystyrene sulfate 15g by mouth

Prepare the patient for hemodialysis treatment

Prepare to administer dextrose 20% and 10 units of regular insulin IV push

Answer and Explanation

The Correct Answer is D

A. Provide a heart-healthy low-potassium diet:

While a heart-healthy low-potassium diet is essential for managing chronic hyperkalemia and preventing future occurrences, it is not the first intervention to implement in a patient with a serum potassium level of 7.5 mEq/L and exhibiting cardiovascular changes. The effects of dietary changes on serum potassium levels are gradual and may take days to have a significant impact. In an acute situation like this, immediate interventions are needed to rapidly lower potassium levels and address the associated cardiovascular risks.

B. Prepare to administer sodium polystyrene sulfate 15g by mouth:

Sodium polystyrene sulfate is a medication used to exchange sodium for potassium in the gastrointestinal tract, effectively lowering serum potassium levels over hours to days. While it is a valid treatment for hyperkalemia, its onset of action is not immediate enough to address the urgent cardiovascular changes seen in severe hyperkalemia. Therefore, it is not the first-line intervention in this scenario.

C. Prepare the patient for hemodialysis treatment:

Hemodialysis is an effective method for rapidly lowering serum potassium levels in cases of severe hyperkalemia. However, it is a more invasive and time-consuming procedure that requires preparation, including vascular access and dialysis setup. It is typically reserved for situations where other interventions have failed or in patients with severe or refractory hyperkalemia. In the context of this scenario, where the patient has a serum potassium level of 7.5 mEq/L and is exhibiting cardiovascular changes, hemodialysis may be considered if initial interventions are not successful, but it is not the first action to implement.

Correct Answer is ["E"]

Explanation

A. Increased pulse rate:

This is a common manifestation of fluid overload. Excess fluid volume can lead to an increase in cardiac output, causing the heart to pump faster and resulting in an increased pulse rate.

B. Decreased blood pressure:

Fluid overload typically leads to increased blood volume, which can initially cause an increase in blood pressure. However, as fluid overload progresses, it can lead to fluid redistribution, venous congestion, and decreased systemic vascular resistance, ultimately resulting in decreased blood pressure.

C. Skeletal muscle weakness:

Skeletal muscle weakness is not a direct manifestation of fluid overload. It is more commonly associated with electrolyte imbalances, such as hypokalemia or hypomagnesemia, which can occur as a consequence of fluid shifts but are not specific to fluid overload itself.

D. Warm and pink skin:

Warm and pink skin is not typically associated with fluid overload. Instead, it is more indicative of adequate tissue perfusion and oxygenation. In fluid overload, skin changes may include edema, cool and clammy skin due to venous congestion, or signs of skin breakdown in areas of pressure.

E. Distended neck veins:

Distended neck veins, specifically jugular venous distention (JVD), are commonly seen in patients with fluid overload, especially if there is right-sided heart failure or increased central venous pressure. JVD is a result of increased venous return to the heart due to fluid accumulation.

A. “All preoperative patients get this medication." B. “The physician prescribed this medication for you." C. "It helps present ulcers from the stress of the surgery." D. “Since you don't have ulcers, I will have to ask."

Correct Answer is C

Explanation

A. “All preoperative patients get this medication.” This statement is too broad and not entirely accurate. While many preoperative patients do receive famotidine (Pepcid), it’s not a standard for all. Medications are prescribed based on individual patient needs and medical history.

B. “The physician prescribed this medication for you.” While this is technically true, it doesn’t provide the patient with an understanding of why the medication is necessary. As a nurse, part of your role is to educate patients about their medications.

C. “It helps prevent ulcers from the stress of the surgery.” This is the correct answer. Famotidine (Pepcid) is given to decrease the amount of acid produced in the stomach, which can help prevent stress ulcers that can occur due to the physical stress of surgery.

D. “Since you don’t have ulcers, I will have to ask.” This statement suggests uncertainty and a lack of knowledge about the medication’s purpose. It’s important for healthcare professionals to understand the medications they administer and be able to explain them to patients.
