A nurse is caring for a hospitalized patientwith a urinary catheter. Which nursing actionbestprevents the patient from acquiring an infection?

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: C

Rationale: The correct answer is C because it includes fiber-rich whole wheat bread, grapes, and walnuts which promote healthy bowel elimination. Whole wheat bread and fruits provide dietary fiber that aids in digestion and prevents constipation. Walnuts are high in omega-3 fatty acids which can also help with bowel regularity. Option A (Broccoli and cheese soup with potato bread) lacks fiber and may cause constipation due to the low fiber content. Option B (Turkey and mashed potatoes with brown gravy) may be low in fiber and high in fat, which can slow down digestion. Option D (Dinner salad topped with hard-boiled eggs, cheese, and fat-free dressing) is a healthier choice but may lack sufficient fiber for promoting healthy bowel elimination compared to option C.

Correct Answer: D

Rationale: Correct Answer: D - Removing all of the patient’s metallic jewelry. Rationale: 1. Safety: Metallic objects can be attracted by the MRI magnet, causing harm to the patient and disrupting the imaging process. 2. Artifact Prevention: Metallic objects can produce artifacts on the MRI images, affecting the diagnostic quality. 3. Patient Comfort: Removing jewelry ensures the patient's comfort during the scan, avoiding discomfort or injury. Summary of Incorrect Choices: A: Not eating or drinking before an MRI is important, but it is not the most crucial action compared to patient safety and image quality. B: Colon cleansing may be necessary for certain types of MRI scans, but it is not universally required and is not the most important action. C: Pain medication may be important for patient comfort, but it is not essential for the actual MRI procedure and does not impact safety or image quality.

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: There is an increased incidence of disease. Low-income immigrants often face barriers to healthcare access, leading to higher rates of undiagnosed and untreated health conditions. This information is crucial for the nurse to plan appropriate care interventions. Incorrect choices: A: Decreased frequency of morbidity is not accurate as low-income immigrants may experience higher rates of illness due to lack of resources. C: Increased level of health is unlikely in this population due to socioeconomic factors affecting health outcomes. D: Decreased mortality rate is not supported as low-income immigrants may have higher mortality rates due to limited access to healthcare.
