When using a client with a serum potassium level of 7.5 mEq/L (7.5 mmol/L), which intervention is most important for the nurse to implement?
Compare muscle strength bilaterally.
Determine apical pulse rate and rhythm.
Measure color and amount of urine.
Assess strength of deep tendon reflexes.
The Correct Answer is B
Hyperkalemia is a condition where there is an elevated level of potassium in the blood.
It can occur in patients with renal disease due to the kidneys’ reduced ability to excrete potassium.
Treatment-related side effects, such as certain medications or chemotherapy, can also contribute to hyperkalemia by altering potassium levels in the body1.
Hyperkalemia can lead to life-threatening cardiac conduction disturbances2.
Therefore, it is important for the nurse to determine the apical pulse rate and rhythm.
Choice A is not correct because comparing muscle strength bilaterally is not the most important intervention for a client with a serum potassium level of 7.5 mEq/L (7.5 mmol/L).
Choice C is not correct because measuring color and amount of urine is not the most important intervention for a client with a serum potassium level of 7.5 mEq/L (7.5 mmol/L).
Choice D is not correct because assessing strength of deep tendon reflexes is not the most important intervention for a client with a serum potassium level of 7.5 mEq/L (7.5 mmol/L).

Correct Answer is B
Explanation
A. Placing food on the unaffected side of the mouth is appropriate for a client who has had a CVA and may have unilateral weakness. This technique helps the client chew and swallow effectively, reducing the risk of aspiration.
B. Raising the head of the bed to 80 degrees is too high and can increase the risk of choking or aspiration by making it harder for the client to control the food bolus during swallowing. A more appropriate position is raising the head of the bed to 45–60 degrees, which facilitates safe swallowing while maintaining comfort. This action requires additional teaching.
C. Positioning the head with the chin tilted slightly downward, known as the chin-tuck position, is a recommended strategy to prevent aspiration. This position helps close the airway during swallowing, reducing the risk of food or liquid entering the trachea.
D. Allowing 30 minutes of rest before feeding is appropriate because it ensures the client is not fatigued, which can compromise swallowing ability and increase the risk of aspiration.
Correct Answer is ["16"]
Explanation
The healthcare provider prescribed 800,000 units of penicillin and the vial available is labeled 50,000 units/mL.
To calculate the number of mL to administer, you need to divide the total number of units prescribed (800,000) by the number of units per mL (50,000).
This gives you a result of 16 mL.
Therefore, the nurse should administer 16 mL of penicillin to the patient.
