Nursing Elites

1. A 6-year-old child comes to the school nurse reporting a sore throat, and the nurse verifies that the child has a fever and a red, inflamed throat. When a parent of the child arrives at school to take the child home, the nurse urges the parent to seek treatment. The nurse is aware that the causative agent may be beta-hemolytic streptococcus, and the illness may progress to inflamed joints and an infection in the heart. What illness is of most concern to the nurse?

• A. Tetanus
• B. Influenza
• C. Scarlet fever
• D. Rheumatic fever

Correct answer: D

Rationale: The correct answer is D, Rheumatic fever. Rheumatic fever can develop as a complication of untreated strep throat caused by beta-hemolytic streptococcus. It is characterized by inflamed joints and can lead to serious complications such as heart infections. Tetanus (choice A) is caused by a bacterial toxin affecting the nervous system, Influenza (choice B) is a viral respiratory illness, and Scarlet fever (choice C) is also caused by streptococcus but is characterized by a sandpaper-like rash and strawberry tongue. However, in the scenario described, the nurse is most concerned about the child developing rheumatic fever due to the potential serious consequences associated with it.

2. What explanation should the nurse give a parent about the purpose of a tetanus toxoid injection for their child?

• A. Passive immunity is conferred temporarily.
• B. Long-lasting active immunity is conferred.
• C. Lifelong active natural immunity is conferred.
• D. Passive natural immunity is conferred temporarily.

Correct answer: B

Rationale: The correct answer is B: Long-lasting active immunity is conferred. Tetanus toxoid injection works by stimulating the child's body to produce its antibodies, providing long-lasting active immunity. Choice A is incorrect because passive immunity is not conferred for life; it is temporary and involves receiving antibodies rather than producing them internally. Choice C is incorrect as the immunity conferred by the tetanus toxoid injection is not lifelong natural immunity but rather active immunity stimulated by the body's immune response. Choice D is also incorrect since passive natural immunity is not conferred by the tetanus toxoid injection, and it is not temporary.

3. A healthcare professional is educating a group of parents on preventing childhood obesity. What should the professional recommend?

• A. Encourage high-calorie snacks
• B. Limit screen time
• C. Encourage fast food as a treat
• D. Allow the child to eat freely

Correct answer: B

Rationale: The correct answer is to limit screen time when preventing childhood obesity. Excessive screen time is associated with a sedentary lifestyle and can lead to increased consumption of unhealthy foods. Encouraging high-calorie snacks (choice A) contradicts the goal of preventing obesity. While fast food as an occasional treat (choice C) can be acceptable in moderation, it should not be encouraged as a preventive measure against obesity. Allowing the child to eat freely (choice D) without guidance can lead to overconsumption of unhealthy foods and contribute to obesity risk.

4. A healthcare professional is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the professional identify as the cause of the polycythemia?

• A. Low tissue oxygen needs
• B. Tissue oxygen needs
• C. Diminished iron level
• D. Hypertrophic cardiac muscle

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs as the body's response to chronic hypoxia by increasing RBC production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect, the heart's structure causes reduced oxygen levels in the blood. This chronic hypoxia stimulates the bone marrow to produce more red blood cells, leading to an elevated RBC count. Choice A is incorrect as low blood pressure is not directly related to polycythemia in this context. Choice C, diminished iron level, is not the cause of polycythemia in tetralogy of Fallot. Choice D, hypertrophic cardiac muscle, is not the primary cause of the elevated RBC count in this case.

5. A parent asks a nurse how to tell the difference between measles (rubeola) and German measles (rubella). What should the nurse tell the parent about rubeola that is different from rubella?

• A. High fever and Koplik spots
• B. Rash on the trunk with pruritus
• C. Nausea, vomiting, and abdominal cramps
• D. Characteristics of a cold, followed by a rash

Correct answer: A

Rationale: Rubeola (measles) is characterized by a high fever and the presence of Koplik spots, which are not seen in rubella (German measles). Therefore, the correct answer is A. Choice B, rash on the trunk with pruritus, is more indicative of rubella rather than rubeola. Choice C, nausea, vomiting, and abdominal cramps, are not specific differentiating symptoms between rubeola and rubella. Choice D, characteristics of a cold followed by a rash, does not specifically distinguish between rubeola and rubella.
