Correct Answer: D

Rationale: When introducing solid foods to infants, iron-fortified cereal is usually recommended as the first food due to its high nutritional value and the importance of iron for the baby's development. Strained fruits (choice A) are often introduced later due to their higher sugar content. Pureed meats (choice B) and cooked egg whites (choice C) are usually introduced after iron-fortified cereal to provide additional sources of protein and other nutrients.

Correct Answer: C

Rationale: Repositioning every two hours is the most effective measure in preventing skin breakdown for a client with a CVA. This practice helps to relieve pressure on the skin, reducing the risk of pressure ulcers. Placing the client in a wheelchair for extended periods (Choice A) can increase pressure on specific areas, leading to skin breakdown. Padding bony prominences (Choice B) can provide some protection but may not address the root cause of pressure ulcers. Massaging reddened bony prominences (Choice D) can potentially worsen the condition by causing further damage to already compromised skin.

Correct Answer: D

Rationale: Shaking the NPH insulin bottle hard can cause air bubbles and affect dosing accuracy; it should be rolled gently instead.

Correct Answer: A

Rationale: The correct answer is A: S3 ventricular gallop. An S3 sound is a common finding in congestive heart failure due to fluid overload in the heart. It is associated with decreased ventricular compliance. Choices B, C, and D are incorrect. An apical click is not typically associated with congestive heart failure. A systolic murmur may be heard in conditions like mitral regurgitation but is not specific to congestive heart failure. A split S2 is associated with conditions like pulmonary hypertension, not congestive heart failure.

Correct Answer: B

Rationale: The correct answer is B because baked chicken and potato chips are gluten-free options suitable for a client with celiac disease. Choice A, a hamburger on a wheat bun, contains gluten, which is harmful to individuals with celiac disease. Choice C, a bacon, lettuce, and tomato sandwich on rye toast, also contains gluten. Choice D, beef and barley soup with crackers, includes gluten from the barley and crackers, making it unsuitable for someone with celiac disease.
