A nurse is reviewing the medical record for a newly admitted client. Which of the following laboratory values should the nurse report to the provider?
Sodium 140 mEq/L
Potassium 5.8 mEq/L
Calcium 9.6 mg/dL
Magnesium 1.9 mEq/L
The Correct Answer is B
Choice A reason:
Sodium 140 mEq/L is incorrect because it falls within the normal range (135-145 mEq/L).
Choice B reason:
A potassium level of 5.8 mEq/L is appropriate because it is above the normal range (typically around 3.5-5.0 mEq/L). Elevated potassium levels, known as hyperkalaemia, can lead to serious cardiac disturbances, including arrhythmias or even cardiac arrest. It is important to notify the healthcare provider promptly so that appropriate interventions can be initiated to address the high potassium level.
Choice C reason:
Calcium 9.6 mg/dL is incorrect because it is within the normal range (8.5-10.5 mg/dL).
Choice D reason:
Magnesium 1.9 mEq/L is incorrect because it is within the normal range (1.5-2.5 mEq/L).

Lung sounds are diminished in posterior lobes,
pain as 8 on a scale of 0 to 10,
Blood pressure 168/84 mm Hg
Correct Answer is B
Explanation
Choice A reason:
Performing percussion over the lower back: While percussion is part of the postural drainage technique, the specific areas to be percussed depend on the client's individualized care plan, which is based on the location of lung segments affected by cystic fibrosis. The nurse should follow the care plan and target the appropriate lung segments for percussion.
Choice B reason:
Covering the area of percussion with a towel is correct. When performing postural drainage with percussion and vibration for a client with cystic fibrosis, it is important to cover the area of percussion with a towel. This helps protect the client's skin and prevent discomfort or injury during the procedure. The towel acts as a barrier between the nurse's hand and the client's skin, allowing for effective percussion while minimizing friction and pressure
Choice Creason:
Scheduling postural drainage after meals: Postural drainage is ideally performed before meals or at least 1-2 hours after meals to avoid potential discomfort or vomiting due to the positioning and movement during the procedure.
Choice Dreason:
Instructing the client to exhale quickly during vibration: Vibration is typically performed during the client's exhalation phase, but the instruction should focus on slow, controlled exhalation rather than quick exhalation.
