Choice A rationale: Increased weight-bearing ability on the affected leg is typically an expected finding, especially as the client begins to recover postoperatively. Enhanced weight-bearing suggests improving strength, mobility, and healing in the affected limb. It does not usually indicate complications. As such, this finding does not necessitate reporting unless accompanied by other concerning symptoms, such as significant pain or changes in circulation.

Choice B rationale: Warmth extending from the left calf to the knee could indicate localized inflammation or infection. However, warmth alone is not definitive for conditions like deep vein thrombosis (DVT) or cellulitis. Without additional findings such as swelling, redness, or pain, it may not be immediately concerning. Nevertheless, it warrants monitoring as a precaution, particularly in postsurgical clients at risk for complications like DVT.

Choice C rationale: A temperature of 38.8° C (101.8° F) is above the normal range of 36.1° C to 37.2° C (97.0° F to 99.0° F) and suggests the possibility of a systemic infection, such as a postoperative wound infection. This finding is significant and must be reported promptly to the healthcare provider for further evaluation and intervention. Early detection and treatment of infections are crucial to prevent complications like sepsis.

Choice D rationale: Itching in bilateral antecubital spaces is a nonspecific symptom that may be attributed to a mild allergic reaction, irritation, or dryness of the skin. While it could indicate a reaction to medications or adhesives used during surgery, it is generally not an urgent concern unless accompanied by additional symptoms like rash, swelling, or respiratory distress. Close monitoring is recommended rather than immediate reporting.

Choice A rationale

Stridor is a high-pitched sound often caused by airway obstruction or inflammation. It is a hallmark of acute laryngotracheobronchitis. The narrowed airways produce turbulent airflow, leading to this characteristic noise during inspiration.

Choice B rationale

The cough type, while clinically relevant, lacks specificity. It does not help differentiate between laryngotracheobronchitis and pneumonia since both conditions may present with cough.

Choice C rationale

Fever commonly accompanies infection but does not distinguish laryngotracheobronchitis from pneumonia. Both conditions are often associated with elevated body temperature due to immune response.

Choice D rationale

Irritability may occur due to hypoxia or fever in various respiratory conditions. However, it is nonspecific and does not directly confirm laryngotracheobronchitis or pneumonia.

Choice A rationale: Stridor during inspiration is a high-pitched, harsh sound caused by an upper airway obstruction. This is a critical finding that requires immediate attention, as it indicates compromised airflow potentially due to conditions like croup, epiglottitis, or foreign body aspiration. Left untreated, the obstruction can worsen, leading to severe hypoxia or respiratory failure. Prompt evaluation and intervention, such as securing the airway, are essential to ensure the child's safety and prevent life-threatening complications.

Choice B rationale: A wet, productive cough is typically associated with lower respiratory tract infections, such as bronchitis or pneumonia. While it warrants medical attention and treatment, it is not an immediate threat to the airway or oxygenation compared to stridor. Management often includes supportive care, hydration, and possibly antibiotics. However, this finding does not pose the acute risk that stridor represents in terms of respiratory distress and airway compromise.

Choice C rationale: A fever of 38.5°C (101.3°F) is a common finding in pediatric clients with infections. It indicates an inflammatory response to illness but is not immediately life-threatening. Fever management involves antipyretics, hydration, and monitoring for signs of more severe infection or sepsis. While elevated temperature requires attention, it does not carry the same urgency as stridor, which signals potential airway obstruction.

Choice D rationale: Irritability reported by the caregiver is a nonspecific symptom that may result from various causes, including pain, discomfort, or fever. While it suggests the child may be unwell, it does not directly indicate a critical condition or imminent danger. Monitoring and addressing the underlying cause of irritability are important, but this finding does not necessitate the same immediate response as stridor, which directly affects airway patency and oxygenation.

Choice A rationale: An oxygen saturation of 95% on 1 L oxygen via nasal cannula is within acceptable ranges, indicating adequate oxygenation for most patients. Normal oxygen saturation values typically range between 95-100%. While slight adjustments might be needed for patients with chronic conditions like COPD, this value does not suggest a critical issue requiring immediate reporting. Monitoring for any declines in oxygen saturation is recommended.

Choice B rationale: The presence of barrel chest often indicates chronic conditions like obstructive pulmonary disease or asthma, linked to air trapping in the lungs over time. While it warrants medical evaluation, it is typically a long-term structural change rather than an acute finding. This symptom does not necessitate immediate reporting unless accompanied by severe respiratory distress or other critical changes in the client’s condition.

Choice C rationale: A respiratory rate of 32/min is above the normal range for adolescents, which is usually 12-20/min. This indicates tachypnea, suggesting respiratory compromise potentially due to hypoxia, acidosis, or infection. While concerning and requiring prompt evaluation, it does not demand immediate reporting compared to hemoptysis, which is more critical due to the risk of airway compromise or hemorrhage.

Choice D rationale: Hemoptysis of 300 mL is a severe and critical finding, indicating significant bleeding within the respiratory tract. This can result from conditions like tuberculosis, pulmonary embolism, or lung malignancies. Immediate reporting is necessary due to the risk of airway obstruction, hypovolemic shock, or respiratory failure. Swift intervention is crucial to manage the bleeding and prevent life-threatening complications.

Choice A rationale

A sunken anterior fontanel suggests reduced intracranial pressure from dehydration. Loss of extracellular fluid volume diminishes intracranial compensation mechanisms, making this a critical dehydration indicator.

Choice B rationale

An increased pulse rate compensates for reduced circulating volume due to dehydration. Tachycardia signals sympathetic nervous system activation to maintain cardiac output.

Choice C rationale

Dry mucous membranes result from reduced salivary gland activity caused by extracellular fluid depletion. Lack of moisture directly indicates dehydration severity.

Choice D rationale

Irritability in children occurs from electrolyte imbalance and reduced perfusion during dehydration. CNS irritability often signals hypovolemia effects on neural function.

Choice A rationale: Steatorrhea during stool analysis, characterized by greasy, foul-smelling stools due to excess fat, is typically associated with malabsorption syndromes such as cystic fibrosis or chronic pancreatitis. While this warrants further evaluation, it is not directly linked to acute respiratory symptoms such as difficulty breathing or coughing up blood. Thus, this finding does not necessitate immediate intervention compared to the urgent risks posed by hemoptysis.

Choice B rationale: Barrel chest, often associated with chronic obstructive pulmonary disease (COPD), reflects long-term structural changes due to chronic air trapping. While it is an important finding requiring ongoing management, it is not an acute issue demanding urgent intervention. It does not directly explain symptoms like hemoptysis or respiratory distress, which indicate more critical underlying conditions requiring immediate attention.

Choice C rationale: An oxygen saturation of 95% on 1 L oxygen via nasal cannula is within the acceptable range for most individuals, with normal oxygen saturation values typically between 95% and 100%. This finding does not indicate severe hypoxemia or a deteriorating respiratory status. As such, it does not require urgent intervention compared to significant bleeding in the respiratory tract.

Choice D rationale: Hemoptysis of 300 mL is a critical finding requiring urgent intervention. This volume of blood indicates severe hemorrhage in the respiratory tract, which can compromise the airway, lead to hypovolemic shock, and cause respiratory failure if not addressed promptly. Immediate evaluation is necessary to identify the source of bleeding and initiate lifesaving treatments such as airway stabilization and hemorrhage control.

Choice A rationale

Minimizing physical contact respects the sensory sensitivities common in children with autism. Overstimulation from touch may exacerbate distress or anxiety, particularly in unfamiliar settings.

Choice B rationale

Semiprivate rooms introduce unpredictable stimuli, which may overwhelm children with autism. Individual spaces ensure reduced sensory overload.

Choice C rationale

Direct eye contact during agitation may provoke anxiety in children with autism, as they often perceive it as intense or threatening.

Choice D rationale

Leaving the television on during the night may increase sensory overload and disrupt sleep patterns. Autism-sensitive environments aim to minimize distractions and provide structure. .

Choice A rationale

Erythema infectiosum does not typically present first on the arms. This viral infection, caused by parvovirus B19, characteristically begins with a bright red rash on the face. It can later spread to the extremities, including arms, but this is a secondary feature.

Choice B rationale

The legs are not the initial site for the rash. Fifth disease progresses from the face to the trunk and limbs. The legs are involved in the later stages, particularly during the rash's spreading phase.

Choice C rationale

The rash in erythema infectiosum first appears on the face, often described as a "slapped cheek" appearance. This hallmark feature is due to parvovirus B19's predilection for vascular endothelial cells in facial capillaries, leading to the characteristic erythema.

Choice D rationale

The abdomen is not the primary location for the rash. While the rash may extend to the trunk and abdomen as it progresses, the initial site is the face. Secondary spread occurs via hematogenous dissemination.

Choice A rationale

The dorsogluteal muscle is not recommended for vaccine administration in toddlers due to its proximity to the sciatic nerve and potential for injury. The anterolateral thigh is the preferred site due to the presence of thicker muscle layers in younger children.

Choice B rationale

Massaging the injection site is not necessary and may lead to irritation or increased discomfort. Vaccine administration guidelines emphasize minimizing trauma to the site rather than stimulating the area post-injection.

Choice C rationale

Obtaining informed consent is essential before administering any vaccine. This step ensures legal and ethical compliance, allowing guardians to understand the risks and benefits associated with the immunization.

Choice D rationale

Aspiration is no longer recommended in vaccine administration according to updated guidelines. Aspiration increases injection time and patient discomfort without evidence of enhancing safety.

Choice A rationale

Daily weights are primarily used for fluid balance monitoring, especially in cases like heart failure or renal conditions. It is not a standard intervention unless specifically indicated for the child’s clinical condition.

Choice B rationale

Routine blood pressure checks every 8 hours are not typically necessary for pediatric patients unless there is a concern for hypertension or critical illness. This intervention is not universally applicable.

Choice C rationale

Seizure precautions are crucial for ensuring patient safety in children with a history or risk of seizures. They include measures such as padded side rails, oxygen availability, and maintaining a safe environment.

Choice D rationale

Sodium-restricted diets are not routinely prescribed for children unless there is an underlying condition like kidney or cardiac disease. This intervention does not apply broadly to pediatric care.
