Correct Answer: A

Rationale: Hyperoxygenating the client before suctioning is crucial to prevent hypoxia during the procedure. By using a manual resuscitation bag with 100% oxygen, the nurse should provide several breaths to the client to ensure sufficient oxygenation before starting suctioning. This approach helps maintain oxygen levels and decreases the risk of hypoxia, which may arise when suctioning interrupts the normal respiratory process. Choices B, C, and D are incorrect because inserting the catheter during exhalation, applying suction while inserting the catheter, and limiting suctioning to 15 seconds do not address the priority of hyperoxygenating the client to prevent hypoxia.

Correct Answer: B

Rationale: Monitoring weight daily is crucial when taking furosemide to detect fluid retention or loss. Furosemide is a diuretic that helps the body get rid of excess water and salt through urine. Changes in weight can indicate fluid shifts, which could be a sign of inadequate response to the medication or worsening condition. Therefore, monitoring weight daily is essential to assess the effectiveness of furosemide therapy and detect any potential issues early on. Choices A, C, and D are incorrect. Avoiding foods high in potassium is more relevant for clients taking potassium-sparing diuretics, not furosemide. Taking furosemide with food is not necessary, as it can be taken with or without food. Increasing salt intake is contradictory to the purpose of furosemide, which aims to eliminate excess salt from the body.

Correct Answer: B

Rationale: The priority finding is the clear fluid leaking from the nose, which could indicate a cerebrospinal fluid leak and potential brain injury. This requires immediate attention to assess for possible cerebrospinal fluid leak, which is a serious complication of head trauma and needs prompt intervention to prevent further complications. While a Glasgow Coma Scale score of 13 may indicate a mild alteration in consciousness, it is not as urgent as assessing for a cerebrospinal fluid leak. Nausea and vomiting are common symptoms after head injuries but do not take precedence over assessing for a potential cerebrospinal fluid leak. Anisocoria (unequal pupils) is also important to note but is not as urgent as identifying a possible cerebrospinal fluid leak in this scenario.

Correct Answer: B

Rationale: The correct answer is B because reducing dairy product intake can help manage symptoms of ulcerative colitis. Dairy products can exacerbate symptoms in some individuals due to their lactose content and may need to be limited or avoided based on individual tolerance levels. Choice A is incorrect because increasing dairy products can worsen symptoms for some ulcerative colitis patients. Choice C is incorrect as while high-fiber foods are generally beneficial, they may exacerbate symptoms during a flare-up. Choice D is also incorrect as while reducing high-fat foods can be beneficial, dairy products are a more specific concern for ulcerative colitis.

Correct Answer: C

Rationale: Assisting the client with early ambulation is crucial in preventing respiratory complications after abdominal surgery. Early ambulation helps to prevent conditions like atelectasis and pneumonia by promoting lung expansion and preventing pooling of respiratory secretions. It also aids in improving circulation, reducing the risk of deep vein thrombosis, and enhancing overall recovery. Instructing the client to exhale into an incentive spirometer (Choice A) is beneficial for lung expansion but is more focused on respiratory therapy rather than preventing complications. Repositioning the client every 8 hours (Choice B) is important for preventing pressure ulcers but is not directly related to preventing respiratory complications. Maintaining the client on bed rest for the first 48 hours (Choice D) can lead to complications such as atelectasis, pneumonia, and deep vein thrombosis due to decreased lung expansion and mobility.
