The parents of a child who has been diagnosed with sickle cell anemia ask why their child experiences pain. What is the most likely cause of the pain?
- A. Inflammation of the vessels
- B. Obstructed blood flow
- C. Overhydration
- D. Stress-related headaches
Correct Answer: B
Rationale: The correct answer is B: Obstructed blood flow. In sickle cell anemia, the sickle-shaped red blood cells can clump together, obstructing blood flow in the vessels. This obstruction leads to tissue hypoxia (lack of oxygen) and necrosis, causing pain. Choice A, inflammation of the vessels, is not the primary cause of pain in sickle cell anemia. Choice C, overhydration, is unrelated to the pathophysiology of sickle cell anemia. Choice D, stress-related headaches, is not a characteristic symptom of sickle cell anemia.

What is the most critical initial intervention for a client who is actively seizing?
- A. Restrain the client to prevent injury
- B. Insert an oral airway
- C. Turn the client to the side
- D. Apply soft restraints to the wrists
Correct Answer: C
Rationale: The most critical initial intervention for a client who is actively seizing is to turn the client to the side. This action helps maintain an open airway and prevents aspiration during a seizure. Restrain the client to prevent injury (Choice A) is incorrect because restraining a client during a seizure can lead to injury. Inserting an oral airway (Choice B) is not recommended as it can cause injury and is not necessary during an active seizure. Applying soft restraints to the wrists (Choice D) is also not recommended as it can lead to harm and does not address the immediate airway management needed during a seizure.
The health care provider is treating a child with meningitis with a course of antibiotic therapy. When should the nurse expect the child to be out of isolation?
- A. When the course of antibiotics is complete
- B. When a negative CNS culture is obtained
- C. When the antibiotics have been initiated for 24 hours
- D. When the child has no symptoms of the disease
Correct Answer: C
Rationale: The correct answer is C because a child with bacterial meningitis should be isolated for at least 24 hours until antibiotic therapy has been initiated. This period allows the antibiotics to start working against the infection, reducing the risk of spreading it to others. Choice A is incorrect because isolation is not solely based on completing the course of antibiotics; the initiation is crucial. Choice B is incorrect as waiting for a negative CNS culture may take longer and delay necessary precautions. Choice D is incorrect as symptom resolution does not guarantee the eradication of the infection and may still pose a risk of transmission.
The nurse explains to the parents of a child with developmental hip dysplasia that the application of a Pavlik harness is necessary. In what position will the harness hold the child's femurs?
- A. Abduction
- B. Adduction
- C. Flexion
- D. Extension
Correct Answer: A
Rationale: The correct answer is A: Abduction. The use of the Pavlik harness is to maintain the hips in abduction for 4 to 6 months to treat developmental hip dysplasia. This position helps in stabilizing the hip joint and promoting proper growth and development. Choices B, C, and D are incorrect because the Pavlik harness specifically aims to hold the child's femurs in abduction, not adduction, flexion, or extension.
What is the hallmark sign of intussusception?
- A. Mucus-like stools
- B. Currant jelly-like stools
- C. Tarry, black stools
- D. Green, soft stools
Correct Answer: B
Rationale: The hallmark sign of intussusception is currant jelly-like stools, which result from the mixture of blood and mucus in the stool due to the sloughing of intestinal mucosa. Mucus-like stools (Choice A) are not typically associated with intussusception. Tarry, black stools (Choice C) are characteristic of gastrointestinal bleeding higher up in the gastrointestinal tract, such as from a peptic ulcer. Green, soft stools (Choice D) are more indicative of rapid transit through the intestines, possibly due to dietary factors or infections such as gastroenteritis.
The nurse is teaching a client how to collect a sputum specimen. Which steps should the nurse instruct the client to follow when collecting sputum?
- A. Breathe deeply, followed by swallowing.
- B. Breathe deeply, followed by spitting into a cup.
- C. Breathe deeply, followed by coughing up the sputum.
- D. Breathe deeply, followed by clearing the throat.
Correct Answer: C
Rationale: The correct answer is to instruct the client to breathe deeply followed by coughing up the sputum. This method ensures that the specimen is collected from the lower respiratory tract and is not contaminated by saliva. Choice A (swallowing) does not result in sputum collection, while choice B (spitting into a cup) may lead to saliva contamination. Choice D (clearing the throat) is not an effective way to collect sputum as it may involve getting rid of saliva, not sputum.
