HESI Fundamentals

Correct Answer: C

Rationale: To collect a wound culture, the nurse should first clean the wound to remove skin flora and then insert a sterile swab from a culturette tube into the wound secretions.

Correct Answer: C

Rationale: In this scenario, if no urine is seen in the tubing after inserting the catheter, it is likely that the catheter is in the vagina rather than the bladder. Leaving the first catheter in place will help locate the meatus more easily when attempting the second catheterization. This approach ensures correct placement of the catheter in the bladder and minimizes the risk of causing unnecessary discomfort or trauma to the patient.

Correct Answer: C

Rationale: Keeping the drainage system below the level of the chest (C) is crucial to ensure proper drainage and prevent backflow of air or fluid into the chest cavity. This position helps maintain the integrity of the closed drainage system. Ensuring the chest tube remains unclamped at all times (A) allows for continuous drainage. Emptying the chest tube (B) should be done as needed, not routinely every 2 hours. Assessing for subcutaneous emphysema (D) is important but not the most critical action in this scenario.

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.

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.
