A client with a history of heart failure arrives at the emergency department describing an onset of fatigue and weakness.

The client has been taking spironolactone 50 mg tablets PO every day.

The nurse receives a report from the lab that the client has a serum potassium level of 6.2 mEq/L (6.2 mmol/L). Which intervention is most important for the nurse to implement?

Compare muscle strength bilaterally.

Observe color and amount of urine.

Determine apical pulse rate and rhythm.

Assess strength of deep tendon reflexes.

Answer and Explanation

The Correct Answer is C

Choice A rationale
Comparing muscle strength bilaterally is important in assessing overall physical health and detecting any potential neuromuscular disorders. However, in the context of a client with a history of heart failure and elevated potassium levels, this would not be the most critical intervention. High potassium levels can lead to hyperkalemia, which can cause serious heart rhythm disturbances.
Choice B rationale
Observing the color and amount of urine can provide valuable information about the client’s hydration status and kidney function. In the case of heart failure, monitoring urine output can help assess the effectiveness of diuretic therapy and the progression of the disease. However, it is not the most immediate concern given the client’s high potassium levels.
Choice C rationale

Determining the apical pulse rate and rhythm is the most important intervention in this scenario. A serum potassium level of 6.2 mEq/L is higher than the normal range (3.5-5.0 mEq/L) and can cause life-threatening heart rhythm abnormalities. Therefore, the nurse should prioritize assessing the client’s heart rhythm to detect any abnormalities caused by this electrolyte imbalance.
Choice D rationale
Assessing the strength of deep tendon reflexes can help identify changes in neuromuscular function and is often used in neurological assessments. However, it is not the most critical intervention in the context of elevated potassium levels and heart failure.

Correct Answer is A

Explanation

Choice A rationale

Restricted activity can help reduce intestinal activity, thereby decreasing inflammation and allowing for tissue healing within the gastrointestinal tract.
Choice B rationale
While controlling diarrhea episodes is an important aspect of managing Crohn’s disease, it is not the primary purpose of activity restriction.
Choice C rationale
Promoting the healing process is a crucial aspect of managing Crohn’s disease. However, the primary purpose of activity restriction is to reduce intestinal activity, which in turn can promote healing.
Choice D rationale
Decreasing abdominal pain is an important aspect of managing Crohn’s disease, but it is not the primary purpose of activity restriction.

A. Obtain equipment for gastric lavage. B. Determine the type of chemical exposure. C. Assess the child for altered sensorium. D. Call the poison control emergency number.

Correct Answer is B

Explanation

Choice A rationale
Gastric lavage is a procedure that involves the insertion of a tube into the stomach to remove its contents and is typically used in cases of poisoning or drug overdose. However, it should not be the first action taken. The type of chemical exposure needs to be determined first to guide appropriate treatment.
Choice B rationale
Determining the type of chemical exposure is crucial as it guides the subsequent steps in management. Different chemicals can have different effects on the body and require different treatments.
Choice C rationale
While assessing for altered sensorium is important in a child exposed to chemicals, it is not the first action. The nurse needs to identify the type of chemical the child was exposed to in order to anticipate potential complications and guide treatment.
Choice D rationale

Calling the poison control emergency number is an important step in managing a case of chemical exposure. However, having information about the type of chemical the child was exposed to can make this call more effective.
