Correct Answer: C

Rationale: The correct answer is 'Cranberry juice stops pathogens' adherence to the bladder.' Cranberry juice maintains urinary tract health by reducing the adherence of Escherichia coli bacteria to cells within the bladder. This helps prevent UTIs. Options A, B, and D are incorrect because orange juice with vitamin C, apple juice for urine acidification, and grapefruit juice for antibiotic absorption do not have the same proven effectiveness in preventing UTIs as cranberry juice does.

Correct Answer: B

Rationale: The correct answer is taking anticoagulants for the past year. Anticoagulants increase the risk of bleeding during surgery, which can lead to complications. It is crucial for the healthcare provider to be aware of this medication. While clients taking birth control pills (option A) may be more prone to developing blood clots, these issues typically arise after surgery. Clients who recently completed antibiotic therapy (option C) or have taken laxatives PRN for the last 6 months (option D) are at lower risk compared to those taking anticoagulants (option B) during surgery.

Correct Answer: D

Rationale: The nurse's first concern should be for the client's safety, so an immediate assessment of the client's situation is needed. Option D is the correct choice as it involves directly addressing the client's emotional state and attempting to understand the reason for the distress. In a vulnerable situation like this, the nurse should take the lead in assessing and communicating with the client. Option A is incorrect as it would delegate the responsibility to someone else when the nurse should be the one to initiate the assessment. Option B is inappropriate as it does not actively address the client's emotional needs or safety. Option C is also incorrect because leaving the client alone without further assessment could potentially endanger the client's well-being.

Correct Answer: A

Rationale: The correct intervention for a nursing diagnosis of risk for infection in an older incontinent client is to maintain standard precautions. The best way to reduce the risk of infection in vulnerable clients is through proper handwashing and adherence to standard precautions. Option B, initiating contact isolation measures, is excessive unless the client has a confirmed infection requiring isolation. Option C, inserting an indwelling urinary catheter, actually increases the risk of infection due to the introduction of a foreign body. Option D, instructing the client in the use of adult diapers, does not directly address the risk of infection and is not as effective as maintaining standard precautions in preventing infection transmission.

Correct Answer: C

Rationale: Water should be instilled into the feeding tube between administering the two medications to maintain the patency of the feeding tube and ensure that the total dose of medication enters the stomach and does not remain in the tube. These liquid medications do not need to be diluted when administered via a feeding tube. Mixing the medications in one syringe can lead to interactions or alterations in the medications' properties. Withdrawing any fluid from the tube before instilling each medication can cause inaccurate dosing and incomplete administration. Therefore, the correct action is to administer water between the doses of the two liquid medications to ensure proper delivery and avoid any complications.
