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).

Correct Answer is C
Explanation
Choice A reason:
The cephalic vein on the back of the right hand is incorrect because it might still involve the same arm as the mastectomy site, and it is important to avoid this side.
Choice B reason:
The radial vein on the left wrist is incorrect because it is not on the opposite side of the mastectomy and could increase the risk of lymphedema.
Choice C reason:
The basilic vein in the right antecubital fossa is the appropriate answer. When inserting an IV catheter for a client who has undergone a right mastectomy, it is generally advisable to avoid the arm on the same side as the mastectomy due to the risk of lymphedema and impaired lymphatic drainage. The basilic vein in the right antecubital fossa (the inner bend of the right elbow) would be a suitable choice in this case, as it is on the opposite side of the mastectomy.
Choice D reason:
The cephalic vein in the left distal forearm is on the same side as the mastectomy and should be avoided to reduce the risk of complications.
Correct Answer is A
Explanation
Choice A reason:
When preparing to insert an IV catheter, placing the tourniquet abovethe proposed insertion site helps facilitate venous distension and makes it easier to locate a suitable vein for the catheter insertion. This technique helps to improve visibility and access to the vein.
Choice B reason:
Placing the extremity in a dependent position (lower than the heart) can increase venous pressure and make it more difficult to insert the catheter.
Choice C reason:
Choosing the most proximal site on the extremity is not always necessary or appropriate. Veins distal to the proposed insertion site should be considered first, as they tend to be smaller and less accessible.
Choice D reason:
Applying a cool compress is not typically done before IV catheter insertion. It might cause vasoconstriction and make it more difficult to access a suitable vein.
