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: A

Rationale: The best action for the nurse is to determine the client's usual bedtime routine and include these rituals in the plan of care as safety allows. By incorporating familiar bedtime rituals that do not compromise the client's safety, the nurse can help the client fall asleep faster and improve the overall quality of care provided to the client.

Correct Answer: A

Rationale: Administering oxygen via a non-rebreather mask is the priority intervention for a client with pulmonary edema to improve oxygenation and address respiratory distress. Adequate oxygenation is essential to support vital organ function. Administering furosemide intravenously, inserting a Foley catheter to monitor urine output, and positioning the client in a high Fowler's position are important interventions but are secondary to ensuring optimal oxygenation in this client with pulmonary edema.

Correct Answer: C

Rationale: Choosing electronic documentation during an interview may hinder the nurse's ability to observe the client's nonverbal cues. Nonverbal communication, such as body language and facial expressions, plays a crucial role in understanding a client's feelings and needs. Focusing on entering data electronically may lead to missing important nonverbal cues that could provide valuable insights into the client's condition or emotions.
