When assessing a client with a serum potassium level of 2.5 mEq/L (2.5 mmol/L), which intervention is most important for the nurse to implement?
Reference Range:
Potassium (K+) 3.5 to 5 mEq/L (3.5 to 5 mmol/L)
Observe color and amount of urine.
Determine apical pulse rate and rhythm.
Compare muscle strength bilaterally.
Assess strength of deep tendon reflexes.
The Correct Answer is B
Choice A reason: Observing the color and amount of urine is important for assessing kidney function and hydration status but is not the most critical intervention for hypokalemia, which can have immediate life-threatening cardiac effects.
Choice B reason: Determining the apical pulse rate and rhythm is the most important intervention. Hypokalemia can lead to serious cardiac arrhythmias, and the apical pulse is the most accurate non-invasive way to assess cardiac rhythm and rate.
Choice C reason: Comparing muscle strength bilaterally is important for assessing the impact of hypokalemia on muscle function, but it is not as immediately life-threatening as cardiac effects.
Choice D reason: Assessing the strength of deep tendon reflexes can help evaluate neuromuscular involvement in hypokalemia but is less critical than monitoring for cardiac arrhythmias.

Correct Answer is D
Explanation
Choice A reason: While the client's medical history and admission assessment provide valuable information, they do not directly measure the current pain experience.
Choice B reason: Vital signs can indicate pain but are not a definitive measure of pain severity as they can be influenced by other factors.
Choice C reason: The frequency of analgesic administration may suggest the level of pain control but does not measure the current pain intensity experienced by the client.
Choice D reason: Asking the client to describe the intensity of the pain is the most direct and effective way to assess pain severity. Pain is subjective, and the client's self-report is considered the gold standard for pain assessment.
Correct Answer is []
Explanation
Choice A reason:
There is no mention of an open wound that requires cleansing and dressing, so this action is not applicable based on the provided patient data.
Choice B reason:
The patient has blanchable redness on both heels and the coccyx, which are signs of pressure injury risk. Ofloading these areas is essential to prevent the development of pressure ulcers.
Choice C reason:
There is no indication of elder abuse in the provided scenario, so contacting adult protective services would not be appropriate.
Choice D reason:
Given the patient's difficulty with mobility and the reported occasional accidents, a bowel training program could help manage his bowel incontinence and improve his quality of life.
Choice E reason:
An enema is not indicated as there is no evidence of constipation or bowel obstruction in the patient's history or nurse's notes.
Condition F reason:
The patient is most likely experiencing pressure injuries, as indicated by the redness on his heels and coccyx, which are common sites for pressure ulcers due to immobility.
Condition G reason:
There is no evidence of elder abuse in the patient's history or nurse's notes. Condition H reason:
Altered nutrition may be a concern due to the patient's reported difficulty eating full meals and less than optimal intake, but it is not the primary condition indicated by the nurse's assessment.
Condition I reason:
There is no evidence of bowel obstruction; the patient's main issue seems to be related to pressure injury and incontinence.
Parameter J reason:
Monitoring wound status is crucial for managing and tracking the healing process of any existing or potential pressure injuries.
Parameter K reason:
While documentation of skin prevention measures is important, it is not as immediate as monitoring wound status and incontinence episodes.
Parameter L reason:
Monitoring incontinence episodes will help evaluate the effectiveness of the bowel training program and any other interventions put in place to manage the patient's incontinence.
Parameter M reason:
Vital signs should always be monitored, but they are not specific to assessing the progress of pressure injury management or bowel training program effectiveness.
Parameter N reason:
Family dynamics are not relevant in this case as the patient lives alone and there is no indication of family involvement in his care.
