Correct Answer: D

Rationale: Understaffing of nursing personnel is a critical organizational factor that can contribute to workplace violence directed at nurses. When there are too few nurses on duty due to understaffing, it can lead to delays in care delivery and inadequate attention to clients' needs. This situation can result in heightened frustration, aggression, or violence from clients or their families towards the nursing staff. On the other hand, the presence of security guards (Choice B) may enhance safety in the workplace and deter violence, making it an incorrect choice. Clients who have short hospital stays (Choice A) and restricted client areas (Choice C) are not directly linked to organizational factors that promote workplace violence against nurses, making them incorrect choices.

Correct Answer: B

Rationale: The correct answer is that the weight gain may be due to the urinary drainage bag not being emptied today, while it was emptied on previous days. This scenario is common and can lead to an increase in weight that is not related to food intake. Choice A is incorrect because assuming visitors are sneaking junk food is speculative and not based on facts. Choice C is incorrect as there is no evidence to suggest the scale is broken. Choice D is incorrect because any unexplained weight gain should be investigated further, even if it seems insignificant at first.

Correct Answer: B

Rationale: Sigmoidoscopy is the correct answer because it specifically examines the sigmoid colon located in the descending colon using an endoscope inserted through the rectum. This procedure captures video and images of the large intestine's lining, helping in the diagnosis of conditions like inflammatory bowel disease or colorectal cancer. Colposcopy, on the other hand, is a procedure for examining the cervix and vagina, not the large intestine. Upper GI involves capturing images of the esophagus and stomach, focusing on the upper gastrointestinal tract, not the large intestine. Cardiac catheterization is a procedure that involves threading a thin instrument through the femoral artery to the heart, used for cardiac interventions and not related to examining the large intestine.

Correct Answer: B

Rationale: When a person is standing in anatomical position, their feet are side by side, and they are facing forward with the toes pointing out to the sides to open the hips. This position allows for proper alignment of the body for anatomical reference. Choice A is incorrect because the feet should not be spread open, but rather side by side. Choice C is incorrect as it does not mention the correct positioning of the feet. Choice D is incorrect as the feet should not be pointed inward, but rather facing out to the sides to open the hips.

Correct Answer: B

Rationale: The most accurate method to assess a patient's respiration rate is to count the breaths simultaneously while counting the pulse rate. This approach ensures that the patient is unaware of the specific focus on their breathing, preventing any conscious alteration in breathing patterns. Choice A is incorrect because informing the patient may lead to altered breathing as the patient may consciously change their breathing pattern. Choice C involves counting the pulse rate first, which is not necessary for assessing respiration rate. Choice D is incorrect as it includes unnecessary steps such as taking the patient's temperature before counting respiration rate, which adds no value to accurately assessing the respiration rate.
