HESI Fundamentals

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: 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: C

Rationale: An elevated AST level following chest pain and shortness of breath is suggestive of myocardial infarction. AST is released from damaged heart muscle cells during a heart attack, indicating cardiac involvement. This enzyme is not specific to liver disease, gallbladder disease, or skeletal muscle injury in this clinical context.

Correct Answer: C

Rationale: The Good Samaritan Act shields healthcare professionals who act in good faith and offer reasonable care from malpractice claims, irrespective of the client's outcome. In this scenario, the nurse stopping to render aid at the accident scene and applying pressure to the bleeding groin wound would likely be covered by the Good Samaritan Act, protecting the nurse from legal repercussions related to the subsequent leg amputation.

Correct Answer: D

Rationale: When inserting an indwelling catheter, the nurse must observe sterile technique to minimize the risk of infections. Sterile technique involves using sterile equipment and maintaining a sterile field to prevent introducing pathogens into the urinary tract.
