Correct Answer: A

Rationale: Continuous bubbling in the water seal chamber should be reported to the healthcare provider immediately. This finding may indicate an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Absence of drainage in the collection chamber (choice B) may signify that the chest tube is blocked, but it does not pose an immediate threat to the client's condition. Tidaling in the water seal chamber (choice C) is an expected finding and indicates proper functioning of the chest tube system. Presence of subcutaneous emphysema around the insertion site (choice D) suggests air leakage but is not as urgent as continuous bubbling in the water seal chamber.

Correct Answer: B

Rationale: The correct answer is B because cleaning the perineal area is a task within the scope of practice for unlicensed assistive personnel (UAPs) and is crucial for preventing infections. Choice A involves a more complex task that requires a healthcare provider's assessment. Choice C involves a sterile procedure that should be performed by licensed staff. Choice D involves specific care for a client with a catheter that exceeds the UAP's scope of practice.

Correct Answer: B

Rationale: The correct answer is B: Position the client in a high-Fowler's position during meals. Placing the client in a high-Fowler's position (sitting upright at a 90-degree angle) helps reduce the risk of aspiration by ensuring that the airway is protected during swallowing. This position facilitates easier swallowing and decreases the likelihood of food or liquids entering the respiratory tract. Encouraging the client to drink water between meals (choice A) does not directly address the risk of aspiration during meals. Providing thickened liquids (choice C) may be necessary for some patients with dysphagia but is not the most important intervention to prevent aspiration. Allowing the client to eat quickly (choice D) without proper positioning and precautions can increase the risk of aspiration.

Correct Answer: B

Rationale: Providing frequent oral care is crucial when a client is NPO to ensure comfort and prevent drying of the oral mucosa. In this situation, the priority is maintaining oral hygiene to prevent complications such as oral mucosa breakdown. Monitoring bowel sounds may be important in assessing bowel activity, but it is not the priority when the client is NPO due to a small bowel obstruction. Encouraging ambulation can be beneficial for other conditions, but in this case, oral care takes precedence. Measuring abdominal girth is more relevant for assessing abdominal distention, which is not the priority when the client is NPO. Therefore, the most important nursing intervention is to provide frequent oral care.

Correct Answer: A

Rationale: The correct action for the nurse to take is to contact the pharmacy and request the prescribed form of aspirin. Enteric-coated medications are designed to dissolve in the intestine, not the stomach, to avoid irritation. Therefore, it is essential to ensure the client receives the correct form of aspirin as prescribed. Instructing the client about the effects of the medication (choice B) is not necessary at this point as the issue is related to the form of the aspirin. Administering the aspirin with a full glass of water or a small snack (choice C) is not appropriate as it does not address the need for the correct form of the medication. Withholding the aspirin (choice D) without consulting the healthcare provider is not advisable as it may lead to a delay in the client receiving the necessary medication.
