Correct Answer: A

Rationale: The priority nursing intervention for a child with cystic fibrosis is administering pancreatic enzymes. This is crucial for managing the condition as it helps in proper digestion of nutrients. Providing respiratory therapy and encouraging physical activity are important aspects of care for cystic fibrosis, but administering pancreatic enzymes takes precedence due to its direct impact on the child's ability to digest and absorb essential nutrients. Encouraging frequent handwashing is a good practice for infection control but is not the priority intervention in this scenario.

Correct Answer: C

Rationale: In a child diagnosed with acute glomerulonephritis, monitoring urine output is a crucial assessment. Acute glomerulonephritis affects the kidneys, leading to decreased urine output due to impaired kidney function. Monitoring urine output helps assess renal perfusion, fluid status, and kidney function. This assessment is essential in determining the effectiveness of treatment and identifying complications. Monitoring blood glucose levels (Choice A) is not directly related to acute glomerulonephritis. Respiratory rate (Choice B) may be important in other conditions but is not a key assessment for acute glomerulonephritis. Monitoring for signs of infection (Choice D) is important in general, but it is not specific to the primary issue of impaired kidney function in acute glomerulonephritis.

Correct Answer: A

Rationale: For a 4-year-old child scheduled for a myringotomy, explaining the procedure in simple terms is essential in helping the child understand what will happen during the surgery and reducing anxiety. Encouraging fluid intake, allowing the child to play with medical equipment, and using play therapy are not directly related to preparing the child for the myringotomy procedure. Therefore, these options are incorrect and not as beneficial as explaining the procedure in simple terms.

Correct Answer: D

Rationale: The correct answer is D: DTaP, IPV, MMR. Before starting kindergarten, the child should receive boosters of DTaP, IPV, and MMR to ensure ongoing protection against diphtheria, tetanus, pertussis, polio, measles, mumps, and rubella. Choice A is incorrect because it includes HepB instead of MMR. Choice B is incorrect as it includes HepB instead of MMR and DTaP instead of IPV. Choice C is incorrect as it includes Hib instead of IPV.

Correct Answer: A

Rationale: Explaining the procedure in simple terms is essential preoperative teaching for a 4-year-old child scheduled for a myringotomy. This approach helps the child understand what will happen during the procedure, reducing anxiety and fear. Encouraging fluid intake is a good general health practice but not directly related to preoperative teaching for this procedure. Allowing the child to play with medical equipment may not be safe or appropriate as it can lead to misunderstanding or fear. Using play therapy can be beneficial but explaining the procedure in simple terms is more direct and effective for preoperative teaching in this case.
