Nursing Process NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B: Obesity. Obesity is a known risk factor for colon cancer as excess body fat, especially around the waist, can lead to inflammation and insulin resistance, increasing the likelihood of cancerous cell growth in the colon. Smoking (choice A) is more strongly associated with lung and other types of cancer, not specifically colon cancer. Heavy alcohol consumption (choice C) is linked to other types of cancer, such as liver and esophageal cancer, but not as strongly to colon cancer. Saccharin consumption (choice D) has not been definitively linked to an increased risk of colon cancer.

Correct Answer: C

Rationale: Rationale for Answer C: Antibodies are produced by the B-cells. B-cells are a type of lymphocyte that differentiate into plasma cells, which are responsible for producing antibodies in response to antigens. This process is a key component of the humoral immune response. Therefore, the statement that antibodies are produced by the B-cells is true. Summary of Incorrect Choices: A: Antibody-mediated defense occurs through the B-cell system, not the T-cell system. T-cells are involved in cell-mediated immunity. B: Cellular immunity is mediated by T-cells, not antibodies produced by B-cells. D: Lymphocytes increasing with an allergic response is not directly related to the production of antibodies by B-cells. Allergic responses involve a different mechanism.

Correct Answer: B

Rationale: The correct answer is B because it acknowledges the patient's behavior is likely due to the stroke affecting his inhibitions. Finding a male assistant respects both the patient's dignity and the nursing assistant's comfort. Choice A is inappropriate as physical violence is never an acceptable response. Choice C lacks empathy and understanding of the situation. Choice D minimizes the seriousness of the behavior and fails to address the issue. B is the best option for promoting a safe and respectful environment for both the patient and staff.

Correct Answer: D

Rationale: The correct answer is D. First, the nurse should put the implant back in place using forceps and a shield for self-protection. This is important to limit the exposure to radiation for both the client and the nurse. Second, the nurse should call for help to ensure proper handling and further assistance. Standing away from the implant (choice A) does not address the immediate need to secure the implant. Picking up the implant with long-handled forceps and placing it in a lead-lined container (choice B) should only be done by trained personnel to prevent further exposure. Leaving the room and notifying the radiation therapy department immediately (choice C) delays the immediate action needed to prevent unnecessary radiation exposure.

Correct Answer: B

Rationale: The correct answer is B: Decreased cardiac output. Fatigue in heart failure is primarily due to decreased cardiac output, leading to reduced oxygen and nutrient delivery to tissues, causing fatigue. Dyspnea (A) is shortness of breath, not fatigue. Dry cough (C) is more associated with conditions like pulmonary issues, not fatigue. Orthopnea (D) is difficulty breathing while lying down, not specifically related to fatigue. Hence, decreased cardiac output is the most likely cause of fatigue in this patient.
