Correct Answer: A

Rationale: Serotonin syndrome, caused by an excess of serotonin, typically presents with symptoms such as altered mental status (confusion), neuromuscular abnormalities (tremors), and autonomic dysfunction (fever). Edema, which refers to swelling caused by fluid retention in the body tissues, is not a common symptom associated with serotonin syndrome. Therefore, the correct answer is 'edema.' Choice A, 'edema,' is the correct answer as it is not typically seen in serotonin syndrome. Choice B, 'fever,' is a symptom of serotonin syndrome, as it can cause autonomic dysfunction. Choice C, 'confusion,' is a common symptom due to altered mental status in serotonin syndrome. Choice D, 'tremors,' is also a common symptom due to neuromuscular abnormalities in serotonin syndrome.

Correct Answer: B

Rationale: Vitamin B12 is the primary nutritional deficiency of concern for a strict vegetarian. While all mentioned vitamins are essential for overall health, vitamin B12 is particularly important for vegetarians as it is mainly found in animal products. A strict vegetarian diet may lack sufficient vitamin B12 intake, leading to potential health issues like anemia and neurological problems. Vitamin C deficiency is more commonly associated with scurvy, which is preventable with a diet rich in fruits and vegetables. Vitamin E deficiency is rare and usually only seen in specific medical conditions. Magnesium deficiency is not typically a primary concern for strict vegetarians as magnesium can be obtained from a variety of plant-based sources.

Correct Answer: D

Rationale: The correct answer is the right lower quadrant. The nurse starts auscultating in this quadrant at the ileocecal valve as bowel sounds are normally always present there. Then, the nurse proceeds to listen for bowel sounds in the other quadrants. Choices A, B, and C are incorrect as the initial placement of the stethoscope should be in the right lower quadrant to assess bowel sounds post-surgery.

Correct Answer: C

Rationale: To assess the function of cranial nerve I (olfactory nerve), the nurse uses a wisp of cotton to test the sense of smell in a client who reports loss of smell. The nurse assesses the patency of the client's nostrils by occluding one nostril at a time and asking the client to sniff. Next, with the client's eyes closed, the nurse occludes one nostril and presents a non-noxious aromatic substance such as coffee, toothpaste, orange, vanilla, soap, or peppermint. Choice A, 'Coffee,' is incorrect because it is used to present non-noxious aromatic substances to assess cranial nerve I. Choice B, 'A tuning fork,' is used to assess the function of cranial nerve VIII (acoustic nerve). Choice D, 'An ophthalmoscope,' is used to assess the internal structures of the eye, not cranial nerve I.

Correct Answer: B

Rationale: The correct answer is 'My child has recently taken a few steps but does not seem stable when standing.' By 18 months of age, children should have taken their first steps and stand well. If a child hasn't made progress by this age, a physical therapy evaluation may be necessary. It is normal for an 18-month-old to start using a spoon to eat. However, the use of two-word phrases is not typically expected until 2 years of age. Separation anxiety is a common developmental phase that typically occurs between 6 and 18 months, so it does not require immediate follow-up. Therefore, the statement about the child not being stable when standing raises a red flag and necessitates further evaluation.
