HESI Fundamentals Test Bank

Correct Answer: C

Rationale: Ensuring the water seal chamber is filled to the appropriate level is crucial to maintain the effectiveness of the chest tube drainage system. This step helps prevent air from entering the pleural space, ensuring proper lung re-expansion. 'Milking' the chest tube is not recommended as it can cause damage to the chest tube and surrounding tissues. Clamping the chest tube is not advisable as it can lead to tension pneumothorax. Securing the chest tube to the bed is important for stability but does not directly impact the functioning of the chest tube.

Correct Answer: C

Rationale: The correct answer is 'C: Sore throat.' Oxygen toxicity can manifest with symptoms like a sore throat, cough, chest pain, difficulty breathing, and fatigue. However, a sore throat can be an early indicator of oxygen toxicity and should prompt immediate attention. Nasal congestion, cough, and fatigue are not specific indicators of oxygen toxicity but could be related to other factors in a client with COPD receiving oxygen therapy.

Correct Answer: D

Rationale: Encouraging additional oral intake of juices and water is the appropriate intervention in this scenario. Dark amber urine can indicate concentrated urine due to dehydration or other factors. By encouraging more fluids, the LPN/LVN can help dilute the urine, reducing the concentration of pigments causing the dark color. Providing additional coffee (Choice A) would not necessarily increase hydration and could potentially have a diuretic effect. Exchanging grape juice for cranberry juice (Choice B) does not address the core issue of hydration. Bringing additional fruit (Choice C) may provide some fluid, but encouraging specific fluids like juices and water would be more effective in diluting the urine.

Correct Answer: D

Rationale: The correct answer is D, Nonmaleficence. Nonmaleficence refers to the principle of 'do no harm.' In this scenario, questioning a potentially harmful prescription for a client with advanced age and unstable status aligns with the principle of nonmaleficence, as the nurse is advocating for the client's safety and well-being. Choice A, Fidelity, refers to being faithful and keeping promises, which is not directly related to the situation described. Choice B, Autonomy, pertains to respecting a patient's right to make their own decisions, which is not the focus of the nurse questioning the prescription. Choice C, Justice, involves fairness and equal treatment, which is not the primary ethical principle at play in this situation.

Correct Answer: A

Rationale: The correct technique for nasotracheal suctioning is to apply intermittent suction when withdrawing the catheter. This method helps prevent damage to the mucosa and is the recommended approach. Continuous suction during insertion (choice B) can cause trauma to the airway lining. Applying suction only during insertion (choice C) is not sufficient for effective removal of secretions. Inserting the catheter while the client is exhaling (choice D) does not follow the standard procedure for nasotracheal suctioning.
