HESI Fundamentals

Correct Answer: D

Rationale: The symptoms of fatigue, muscle weakness, leg cramps, and cardiac dysrhythmias are classic manifestations of hypokalemia. Potassium plays a vital role in muscle function and cardiac conduction, so a deficiency can lead to these symptoms. Checking the client's laboratory values for potassium levels will help confirm the presence of hypokalemia.

Correct Answer: D

Rationale: A temperature of 100.4�F (38�C) (D) is the most concerning finding for a client receiving total parenteral nutrition (TPN) as it may indicate an infection, which poses a significant risk. Monitoring blood glucose level (A), blood pressure (B), and serum albumin (C) are also important, but an elevated temperature suggests a potential serious complication that requires immediate attention.

Correct Answer: B

Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.

Correct Answer: C

Rationale: Pinching the skin before inserting the needle is essential in elevating the subcutaneous tissue away from the muscle. This technique ensures that the medication is administered into the correct tissue layer, promoting proper absorption and decreasing the risk of injecting into muscle tissue.

Correct Answer: D

Rationale: When caring for patients from diverse cultural backgrounds, it is essential to respect and consider their cultural norms and practices while providing healthcare. Understanding and incorporating cultural beliefs and values can enhance the quality of care and improve patient outcomes.
