Correct Answer: C

Rationale: The correct answer is C. Offering a variety of foods in small portions is appropriate for a 2-year-old toddler as it helps provide balanced nutrition and allows the child to explore different tastes and textures. Choice A is incorrect because whole milk is recommended up to 2 years old, not until 3 years old. Choice B is incorrect as excessive juice intake can lead to excessive sugar consumption and is not recommended. Choice D is incorrect as popcorn may pose a choking hazard for toddlers and is not a suitable alternative to sweets.

Correct Answer: A

Rationale: An elevated white blood cell count (WBC 15,000/mm�) is a common indicator of infection as the body increases WBC production to fight off pathogens. In conditions like infections, inflammation, or stress, the WBC count can rise. The other options, hemoglobin, platelet count, and sodium levels, are not typically specific indicators of infection. Hemoglobin measures the oxygen-carrying capacity of red blood cells, platelet count assesses clotting ability, and sodium levels indicate electrolyte balance.

Correct Answer: D

Rationale: Encouraging additional oral intake of juices and water is the appropriate intervention in this scenario. Dark amber urine can indicate concentrated urine due to dehydration or other factors. By encouraging more fluids, the LPN/LVN can help dilute the urine, reducing the concentration of pigments causing the dark color. Providing additional coffee (Choice A) would not necessarily increase hydration and could potentially have a diuretic effect. Exchanging grape juice for cranberry juice (Choice B) does not address the core issue of hydration. Bringing additional fruit (Choice C) may provide some fluid, but encouraging specific fluids like juices and water would be more effective in diluting the urine.

Correct Answer: A

Rationale: In paralytic ileus, bowel sounds are typically absent or significantly reduced due to decreased motility of the intestines. This absence of bowel sounds is a key characteristic used in diagnosing paralytic ileus. Hyperactive bowel sounds are not expected in this condition as there is a lack of normal peristalsis. Normal bowel sounds would not be present in paralytic ileus, and hypoactive bowel sounds, which indicate decreased bowel motility, are more commonly associated with conditions like postoperative ileus or constipation, rather than paralytic ileus.

Correct Answer: A

Rationale: The correct answer is to administer insulin as prescribed. When a client with diabetes mellitus presents with a critically high blood glucose level like 600 mg/dL, the priority action is to lower the blood glucose level promptly to prevent complications. Insulin is the appropriate medication to rapidly reduce high blood glucose levels. Administering oral hypoglycemic agents may not act quickly enough in this critical situation. While monitoring blood glucose levels frequently is important, immediate intervention to lower the high blood glucose level takes precedence. Providing a high-calorie diet is contraindicated in this scenario as it would further elevate the blood glucose level.
