LPN Nutrition Practice Test

Correct Answer: B

Rationale: Rapid breathing is a common sign of a respiratory infection in infants. When infants have a respiratory infection, their breathing may become rapid as their body tries to get more oxygen. This symptom is often seen alongside cough and fever. Increased appetite (Choice A) is not typically associated with respiratory infections but can be seen in other conditions. Decreased urine output (Choice C) is more indicative of dehydration or kidney issues rather than a respiratory infection. Lethargy (Choice D) can be a symptom of various illnesses but is not as specific to respiratory infections as rapid breathing.

Correct Answer: B

Rationale: The correct answer is monitoring blood cell counts. During chemotherapy, it is crucial to monitor blood cell counts to detect potential side effects such as neutropenia (low white blood cell count) and anemia (low red blood cell count). These conditions can increase the risk of infections and fatigue. Monitoring blood glucose levels (Choice A) is not typically a primary concern in children receiving chemotherapy unless they have pre-existing conditions like diabetes. Weight gain (Choice C) and skin elasticity (Choice D) are not directly related to monitoring the effects of chemotherapy in children. Therefore, the most important parameter to monitor in a child receiving chemotherapy is blood cell counts.

Correct Answer: B

Rationale: A low-phenylalanine diet is crucial for managing PKU to prevent neurological damage and maintain normal development. Phenylalanine is an amino acid found in protein-containing foods, and individuals with PKU have difficulty metabolizing it. Consuming foods low in phenylalanine helps prevent the buildup of toxic byproducts in the body. Choices A, C, and D are incorrect. A high-fiber diet, increased dairy intake, and high-sodium diet are not specific dietary considerations for PKU management. In fact, dairy products are a source of protein and phenylalanine, which should be limited in PKU.

Correct Answer: B

Rationale: When a parent expresses concerns about their child's frequent ear infections, suggesting an ENT specialist evaluation is the most appropriate response. This specialist can conduct a thorough examination to identify the underlying cause of the recurrent infections and recommend the most suitable treatment. Recommending over-the-counter ear drops (Choice A) may not address the root cause of the issue and could potentially lead to inappropriate treatment. Advising on increasing fluid intake (Choice C) and encouraging more physical exercise (Choice D) are unrelated to addressing the specific concern of frequent ear infections.
