HESI Fundamentals

Correct Answer: B

Rationale: Theophylline should be administered on a regular around-the-clock schedule to provide the best bronchodilating effect and reduce the potential for adverse effects. The correct dosing schedule of 8 a.m., 4 p.m., and midnight ensures that the client receives consistent dosing throughout the day. Other options do not provide the necessary around-the-clock coverage. It's important to note that food may affect the absorption of the medication, which is why the dosing schedule should not be tied to meal times.

Correct Answer: A

Rationale: The correct instruction for preparing a client for a colonoscopy is to drink clear liquids for 24 hours before the procedure. This step helps to ensure the bowel is adequately cleared for the colonoscopy, allowing for better visualization and examination of the colon.

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: C

Rationale: To evaluate the effectiveness of atorvastatin (Lipitor), the nurse should monitor liver function tests (LFTs) (C) because this medication can impact liver function. Complete blood count (CBC) (A), serum potassium level (B), and serum cholesterol level (D) are not directly indicative of the medication's effectiveness in managing coronary artery disease.

Correct Answer: D

Rationale: The priority action for the nurse in this situation is to gently lower the client to the floor. This action helps prevent injury to both the client and the nurse. It is important to ensure a safe environment and protect the client from falling, as well as to maintain the nurse's own safety while providing care.
