Correct Answer: C

Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway. Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea. Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea. Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.

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: D

Rationale: The correct answer is 'Never demonstrated.' Despite the patient sleeping a total of 6 hours daily, it is not achieved in one uninterrupted session at night as per the desired outcome. The patient's habit of taking a 2-hour afternoon nap also affects the evaluation. Therefore, the outcome should be evaluated as 'Never demonstrated.' Choice A, 'Consistently demonstrated,' is incorrect because the desired outcome of sleeping for a minimum of 5 hours nightly in one session is not met. Choice B, 'Often demonstrated,' is incorrect as the patient's sleep pattern does not consistently align with the desired outcome. Choice C, 'Sometimes demonstrated,' is also incorrect as the patient's sleep pattern does not meet the specific criteria set in the desired outcome.

Correct Answer: D

Rationale: The statement about hearing evil voices indicates that the patient is experiencing auditory hallucinations, which is a significant symptom that requires immediate attention and intervention. This symptom can be associated with serious mental health conditions like psychosis. Choices A, B, and C are more general statements that do not provide specific information about the patient's mental health status or symptoms, making them less urgent and not as critical for the plan of care compared to the presence of auditory hallucinations.

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.
