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: Suctioning the patient in a supine position and pulling the bed sheets tightly across their feet can lead to foot drop, which is harmful for a patient with right-sided hemiplegia. This action can exacerbate muscle weakness and impair circulation in the affected limb. It is crucial to avoid actions that may compromise the patient's safety and well-being, such as causing foot drop in this scenario.

Correct Answer: B

Rationale: If a sterile field becomes wet or damp during a procedure, it is considered contaminated as moisture can allow organisms to wick from the surface and compromise the sterility of the field. It is essential to maintain the integrity of the sterile field to prevent infections and ensure patient safety.

Correct Answer: A

Rationale: The priority nursing action is to restore circulation by loosening the restraint (A) because blue fingers (cyanosis) indicate decreased circulation. Comparing hand color bilaterally (C) and palpating the right radial pulse (D) are important assessments to gather more information, but they do not have the priority of addressing the decreased circulation by loosening the restraint. Applying a pulse oximeter (B) is not indicated in this scenario as it measures the saturation of hemoglobin with oxygen, which is not relevant when cyanosis is related to mechanical compression from the restraints.
