Correct Answer: A

Rationale: The correct answer is A: Maintaining a closed urinary drainage system. This action prevents infection by reducing exposure to external pathogens. Step 1: A closed system minimizes the risk of contamination. Step 2: It prevents entry of bacteria into the urinary tract. Step 3: Regularly emptying the drainage bag helps maintain a closed system. Step 4: This action promotes patient safety and reduces infection risk. Summary: Choice B (strict clean technique) may reduce infection risk during catheter insertion but does not prevent infections post-insertion. Choice C (replacing drainage bag once per shift) increases infection risk due to frequent disconnection. Choice D (fully inflating catheter balloon) is unrelated to infection prevention.

Correct Answer: A

Rationale: The correct answer is A: Tumor lysis syndrome (TLS). In this scenario, the oncology patient has completed treatment for non-Hodgkin lymphoma. TLS is a potential complication post-treatment due to the rapid breakdown of cancer cells, leading to release of intracellular contents like potassium, phosphorus, and uric acid into the bloodstream. This can result in electrolyte imbalances, renal failure, and cardiac arrhythmias. The nurse should assess for signs such as hyperkalemia, hyperphosphatemia, hypocalcemia, and elevated uric acid levels. Monitoring renal function and fluid status is crucial. Summary of other choices: B: Syndrome of inappropriate ADH (SIADH) is characterized by excessive release of antidiuretic hormone leading to water retention and dilutional hyponatremia. Not typically associated with post-treatment complications in oncology patients. C: Disseminated intravascular coagulation (DIC)

Correct Answer: C

Rationale: The correct answer is C. Computer competency does not equate to informatics competency. Informatics involves more than just basic computer skills; it encompasses the ability to use technology to manage and analyze data for improved healthcare outcomes. A: This is a correct statement about informatics proficiency. B: This is also a correct statement about the skills needed for informatics. D: This is a true statement about nursing informatics being a recognized specialty, but it does not indicate a need for follow-up. In summary, choice C is incorrect as it oversimplifies the concept of informatics, while choices A, B, and D provide accurate information related to informatics.

Correct Answer: D

Rationale: Correct Answer: D - Proper hand hygiene techniques Rationale: 1. Clostridium difficile is mainly spread through contact with contaminated surfaces. 2. Proper hand hygiene is the most effective way to prevent the spread of bacteria. 3. Hand hygiene removes bacteria from hands, reducing the risk of transmission. 4. Appropriate disposal (A) is important but doesn't directly prevent spread. Monthly in-services (B) and mandatory cultures (C) are not as effective as hand hygiene in preventing transmission.

Correct Answer: B

Rationale: The correct answer is B: Provide the patient with relevant information about expected recovery. This option addresses the patient's anxiety by providing her with concrete information about what to expect after the procedure. By knowing the expected recovery process, the patient can feel more in control and prepared, which can help alleviate fears. Summary: A: Providing written material on the procedure does not directly address the patient's fears about the upcoming surgery and cancer diagnosis. C: Giving the patient current information on breast cancer survival rates may increase anxiety rather than alleviate it, as it focuses on statistics rather than the individual patient's concerns. D: Offering alternative treatment options may not be appropriate at this stage when the patient is already scheduled for a modified mastectomy. It may add confusion and further anxiety.
