Correct Answer: A

Rationale: The correct answer is to administer the feeding over 30 minutes. This slow administration helps prevent complications like nausea. Placing the child in a supine position after the feeding can increase the risk of aspiration, making choice B incorrect. Changing the feeding bag and tubing every 3 days is important for infection control and hygiene but is not directly related to the administration process, making choice C incorrect. Warming the formula in the microwave is not recommended as it can create hot spots that may burn the child's mouth or esophagus, so choice D is incorrect.

Correct Answer: D

Rationale: The correct answer is D: 'Hct 40%'. An abnormal hematocrit (Hct) level can indicate various conditions such as dehydration, overhydration, or blood disorders, and requires immediate attention from the healthcare provider. Choices A, B, and C are within normal ranges and do not typically warrant immediate provider notification. Hgb 12.5 g/dL (Choice A) is a normal hemoglobin level, Platelets 250,000/mm3 (Choice B) is a normal platelet count, and WBC 14,000/mm3 (Choice C) is slightly elevated but not significantly high to require urgent reporting.

Correct Answer: D

Rationale: The correct answer is to instruct the client to perform the peak flow test before using any bronchodilators. This is important because it provides the most accurate baseline measurement of lung function. Choice A is not necessarily crucial for the accuracy of the test. Choice B describes the technique for spirometry, not peak flow meter use. Choice C, while important for tracking trends, is not directly related to the accuracy of the initial measurement.

Correct Answer: C

Rationale: Enuresis is the correct finding to expect in a school-age child with a urinary tract infection. Enuresis, or involuntary urination, is a common symptom of UTIs in children. Periorbital edema (Choice A) is not typically associated with UTIs. Decreased frequency of urination (Choice B) is less likely in UTIs as there is often an increased urge to urinate. Diarrhea (Choice D) is not a common symptom of UTIs and is more indicative of gastrointestinal issues.

Correct Answer: B

Rationale: Fresh vegetables are an excellent choice for clients on a low-sodium diet as they are naturally low in sodium. Pickles, canned soup, and smoked salmon are high in sodium and should be avoided by clients following a low-sodium diet. Pickles are pickled in a brine solution high in sodium, canned soup usually contains added salt for preservation, and smoked salmon is a processed food that typically has a high sodium content.
