A nurse is caring for a client who arrives at the emergency department and reports vomiting and diarrhea for the past 3 days. The client's serum potassium level is 2.8 mEq/L. Which of the following interventions should the nurse implement first?
Listen to the client's bowel sounds.
Initiate cardiac monitoring for the client.
Check the client's hand grasps.
Administer an IV potassium drip.
The Correct Answer is B
Choice A reason:
Listening to the client's bowel sounds should not be implemented. It is important for assessing the gastrointestinal status, but the priority in this situation is to address the potential cardiac complications of hypokalaemia.
Choice B reason:
Initiating cardiac monitoring for the client should be implemented. A serum potassium level of 2.8 mEq/L is significantly low (normal range is typically around 3.5-5.0 mEq/L). Low potassium levels, known as hypokalaemia, can lead to serious cardiac arrhythmias and other complications. Therefore, the nurse should prioritize cardiac monitoring to assess for any potential changes or abnormalities in the client's heart rhythm due to the low potassium levels.
Choice C reason:
Checking the client's hand grasps should not be implemented. It is a test for muscle strength and can be indicative of hypokalaemia, but initiating cardiac monitoring is more critical at this point.
Choice D reason:
Administering an IV potassium drip may be necessary, but initiating cardiac monitoring takes precedence as the first action to ensure the client's heart rhythm is stable before addressing the potassium imbalance.

Correct Answer is C
Explanation
Choice A Reason:
Changing the catheter dressing daily - While it's important to maintain the dressing and keep it clean and dry, changing the dressing daily might not be necessary. The dressing should be changed according to facility policy and based on assessment findings.
Choice B Reason:
Cleaning the insertion site using 20 mL of hydrogen peroxide - Hydrogen peroxide is not recommended for cleaning PICC line insertion sites, as it can cause tissue irritation. The insertion site should be cleaned with an appropriate antiseptic solution per facility guidelines.
Choice C Reason:
Use a 10-mL syringe to flush the line. When completing discharge teaching for a client with a peripherally inserted central catheter (PICC) line, the nurse should include instructions regarding the proper care of the line. Using a 10-mL syringe to flush the line is the appropriate practice to prevent excessive pressure within the catheter and minimize the risk of catheter damage or rupture.
Choice D Reason:
Not elevating the arm above the level of the heart - Elevation of the arm above the heart level is generally not contraindicated for a PICC line. However, it's important to avoid activities that could lead to kinking or pulling on the line. The nurse should provide specific instructions regarding arm movement and care to the client.
Correct Answer is C
Explanation
Choice A Reason:
Bradycardia - Bradycardia is not a typical symptom of a haemolytic transfusion reaction.
Choice B Reason;
Hypertension - Hypertension is not a common manifestation of a haemolytic transfusion reaction.
Choice C Reason:
Back pain A haemolytic transfusion reaction is a severe and potentially life-threatening complication that can occur when the immune system reacts against the transfused red blood cells. Back pain is a classic symptom of a haemolytic transfusion reaction. It is often accompanied by other symptoms such as fever, chills, chest pain, dyspnoea, nausea, vomiting, haematuria, and hemoglobinuria (presence of haemoglobin in the urine).
Choice D Reason:
Chills - Chills can occur in various types of transfusion reactions, including haemolytic reactions, but they are not as specific as back pain for indicating a haemolytic transfusion reaction.
