Pleural friction rub is characterized by all the following EXCEPT:

Correct Answer: A

Rationale: In this question, the correct answer is A) It is audible during inspiratory phase of breathing. A pleural friction rub is a specific lung sound characterized by a grating, rubbing, or squeaking noise that occurs during both inspiration and expiration, not just during the inspiratory phase. This sound is typically heard when the inflamed visceral and parietal pleura rub against each other during respiration. Option B) It may be associated with pain is incorrect because pleural friction rubs are typically not associated with pain. They are primarily a noise heard during auscultation. Option C) It is unaltered by coughing is incorrect because coughing can sometimes temporarily change or diminish the sounds heard during auscultation, including pleural friction rubs. Option D) Better heard with chest piece of stethoscope tightly placed over chest wall is incorrect because pleural friction rubs are best heard with the diaphragm of the stethoscope, not the chest piece, placed lightly on the chest wall to avoid amplifying extraneous noises. Educationally, understanding lung sounds like pleural friction rubs is crucial for nurses and healthcare providers to accurately assess and diagnose respiratory conditions in pediatric patients. Differentiating between various lung sounds can help in determining the underlying pathology and providing appropriate interventions for the patient. Mastering this skill is essential for pediatric nurses to provide high-quality care to their young patients with respiratory issues.

Correct Answer: A

Rationale: In pediatric nursing, understanding the different types of shock is crucial for providing effective care. In the context of obstructive shock, the correct answer is A) Mechanical obstruction to ventricular outflow. This type of shock occurs when there is an obstruction to blood flow out of the heart, leading to decreased cardiac output and inadequate tissue perfusion. Examples include conditions like cardiac tamponade or pulmonary embolism. Option B) Airway obstruction is incorrect as it pertains to respiratory issues rather than obstructive shock related to cardiac output. Option C) Generalized vasoconstriction is more indicative of distributive shock, not obstructive shock. Option D) Hypovolemia refers to a decrease in blood volume, which can lead to hypovolemic shock but is not specific to obstructive shock. Educationally, it is important for nursing students preparing for the NCLEX to differentiate between the types of shock, understand their unique characteristics, and recognize the appropriate interventions for each. By grasping these concepts, nurses can effectively assess and manage pediatric patients experiencing various types of shock, ultimately improving patient outcomes.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) 10. The Glasgow Coma Scale (GCS) assesses the level of consciousness in a patient with a head injury. A GCS score of 10 indicates that the patient is opening their eyes to pain stimulus, confused in their responses, and withdrawing from pain, which aligns with the patient's presentation in the question. Option A) 8 is incorrect because a GCS score of 8 would indicate a more severe level of neurological compromise, such as not opening eyes to pain or having a more limited response to stimuli compared to the patient described in the question. Option C) 11 is incorrect because a GCS score of 11 would typically involve a higher level of consciousness and more appropriate responses than what the patient in the question is exhibiting. Option D) 13 is incorrect as it would suggest a near-normal level of consciousness and responsiveness, which is not consistent with the patient's presentation of being confused and withdrawing from pain. Educationally, understanding the GCS is crucial for nurses caring for pediatric patients, especially in emergency and critical care settings. It helps in assessing the severity of head injuries, guiding treatment decisions, and monitoring changes in neurological status over time. Nurses must be able to accurately interpret GCS scores to provide appropriate care and communicate effectively with the healthcare team.

Correct Answer: A

Rationale: In the context of pediatric patients, understanding the characteristics of obstructive shock is crucial for nurses preparing for the NCLEX. The correct answer is A) Mechanical obstruction of ventricular outflow. Obstructive shock occurs when there is a physical obstruction to blood flow, leading to impaired cardiac function. This can result from conditions such as cardiac tamponade, tension pneumothorax, or pulmonary embolism, which physically impede the heart's ability to pump effectively. Option B) Airway obstruction is incorrect because it refers to a blockage in the air passages, which can lead to respiratory distress but is not specific to obstructive shock. Option C) Generalized vasoconstriction is more characteristic of distributive shock, such as septic shock, where there is widespread vasodilation rather than obstruction. Option D) Hypovolemia is associated with hypovolemic shock due to a decrease in circulating blood volume, not mechanical obstruction. Educationally, nurses need to differentiate the types of shock to provide appropriate and timely interventions for pediatric patients. Understanding the distinct features of each type of shock is essential for effective patient assessment and management. By grasping the specific characteristics of obstructive shock, nurses can promptly recognize the condition and initiate appropriate interventions to improve patient outcomes.

Correct Answer: B

Rationale: In pediatric nursing, it is crucial to understand the signs and symptoms of circulatory failure to provide prompt and effective care to children. In this question, option B, "Marked tachypnea with recessions," is the correct answer as it is a sign of respiratory distress rather than circulatory failure. Tachypnea with retractions typically indicates increased work of breathing and points towards a respiratory issue rather than a circulatory problem. Option A, "Cyanosis despite supplied O2," is indicative of poor oxygenation despite oxygen therapy, which is a sign of circulatory compromise. Cyanosis results from inadequate oxygen delivery to tissues and can be a manifestation of circulatory failure. Option C, "Gallop rhythm/murmur," and Option D, "Enlarged tender liver," are also signs of circulatory compromise. A gallop rhythm or murmur can indicate cardiac dysfunction, while an enlarged tender liver can be a sign of congestive heart failure or hepatic congestion due to circulatory issues. Educationally, understanding these distinctions is vital for nurses caring for pediatric patients. Recognizing the specific signs of circulatory failure versus respiratory distress can guide appropriate interventions and help prevent further deterioration in a child's condition. It is essential to differentiate between these clinical manifestations to provide targeted and effective care in a pediatric healthcare setting.
