Questions on Intravenous fluids (IV) Fluids and their uses

Correct Answer is C

Explanation

Lethargy and irritability can be signs of dehydration, but they are nonspecific and can occur in various pediatric conditions. Sunken eyes and fontanelle, on the other hand, are more specific to dehydration, especially in infants.

Correct Answer is A

Explanation

Certain medical conditions, such as diabetes or kidney disease, can lead to chronic dehydration. However, these conditions are not mentioned in the scenario provided. In the absence of information about underlying medical conditions, gastrointestinal illnesses remain the most likely cause of the child's dehydration.

Correct Answer is ["A","B","C","D"]

Explanation

Increased energy and playfulness are not typical signs of dehydration. Dehydrated children are more likely to be lethargic and irritable due to the physiological stress on their bodies.

Correct Answer is C

Explanation

Assessing the child's history is fundamental in understanding the underlying cause of dehydration. Recent fluid intake and urine output patterns help determine the balance between intake and output. Symptoms such as diarrhea, vomiting, and fever indicate potential causes of fluid loss. Additionally, evaluating the child's overall health and any recent illnesses provides context for the dehydration, guiding appropriate treatment.

Correct Answer is ["A","B","C"]

Explanation

Sunken eyes and fontanelle in infants are physical signs of dehydration, not etiological factors. Sunken eyes are due to decreased tissue turgor, indicating dehydration. Fontanelle, the soft spot on an infant's head, can appear sunken in dehydration. These signs are crucial in assessing the severity of dehydration during physical examination but do not contribute to the causes of dehydration.

Correct Answer is C

Explanation

"The child's vaccination history" is not relevant to the assessment of dehydration. While vaccination history is essential for preventive healthcare, it does not provide any information about the child's current hydration status or fluid balance.

Correct Answer is B

Explanation

Suggesting the child's need for frequent, heavy meals is not an appropriate way to prevent dehydration. In fact, heavy meals can sometimes worsen dehydration as they may be difficult to digest, leading to an increased risk of vomiting and diarrhea, which exacerbate fluid loss.

Correct Answer is ["A","C","E"]

Explanation

Educating the child and caregivers about dehydration is an important nursing intervention. Teaching them about the signs and symptoms of dehydration, the importance of ORS, and how to prevent it in the future is essential for the child's well-being and for preventing future episodes of dehydration.

Correct Answer is A

Explanation

Excessive thirst and urination are common signs of dehydration but are not indicative of electrolyte imbalances. These symptoms occur as the body attempts to compensate for fluid loss by increasing thirst and increasing urine output. Electrolyte imbalances are more likely to manifest as muscle weakness and cardiac arrhythmias.

Correct Answer is B

Explanation

"Shoe size and clothing size.”. Rationale: Shoe size and clothing size are not relevant for assessing dehydration. These measurements are related to a child's growth and body structure but do not provide information about their hydration status.

Correct Answer is D

Explanation

Fluid deficit (in mL) = body weight (in kg) x 0.04. Rationale: This is The correct answer. The appropriate fluid deficit calculation for a child who weighs 12 kg with moderate dehydration is to multiply their body weight by 0.04. For this child, it would be 12 kg x 0.04 = 480 mL. This formula is a commonly used guideline to estimate fluid deficit in cases of dehydration.

Correct Answer is D

Explanation

No explanation

Correct Answer is C

Explanation

No dehydration is defined as less than a 3% loss of body weight. The clinical manifestations observed in the child, as described in the scenario, clearly indicate dehydration. In this case, the child's signs and symptoms align with the classification of severe dehydration, which is characterized by a loss of ≥10% of body weight. These symptoms include dry mucous membranes, decreased urine output, and decreased skin turgor. It's crucial to recognize the severity of dehydration accurately to initiate the appropriate treatment and prevent complications.

Correct Answer is C

Explanation

Collaboration within the healthcare team is important, but this statement doesn't specifically address the understanding of fluid replacement and dehydration management. The correct response is choice C because it highlights the critical aspect of continuous assessment, which is essential to ensure that the child's hydration status is being monitored effectively during treatment.

Correct Answer is ["A","B","D","E"]

Explanation

Communication with physicians, nutritionists, and other healthcare professionals is vital for comprehensive care. Dehydration management often involves a multidisciplinary approach to address the child's overall health and nutritional needs. Selecting all of these options (A, B, D, and E) ensures a comprehensive approach to managing dehydration in a child. It involves assessment, calculation, monitoring, and collaboration with healthcare professionals for the best outcome.

Assess the degree of dehydration based on clinical signs and symptoms. Rationale: While assessing the degree of dehydration is important, it should not be the only action taken. Monitoring the child's response to treatment and adjusting the plan is equally crucial. Dehydration assessment is typicall

All these measures are necessary to prevent dehydration in children. Rationale: This is The correct answer. Preventing dehydration in children involves a combination of measures, including ensuring appropriate fluid intake, monitoring for signs of dehydration, and encouraging electrolyte solutions d

D5W (5% dextrose in water). Rationale: D5W is a hypotonic solution and should not be used for rehydration in a client with hyponatremia. It can exacerbate the electrolyte imbalance and is not suitable for addressing dehydration.

D5W (5% dextrose in water) is a solution that primarily provides dextrose for energy, not suitable for hypovolemia and burns. It can cause dilutional hyponatremia if used as the primary fluid in hypovolemic patients.

<p><strong>Choice D: Decreased appetite</strong> Loss of appetite (anorexia) is a common symptom in children. Acute illness in childhood is often associated with transient loss of appetite. However, decreased appetite is not typically a direct symptom of hypoglycemia.</p>

D5W (5% dextrose in water) is not recommended for cerebral edema because it contains dextrose and may not adequately address the underlying issue of increased intracranial pressure associated with cerebral edema.

Plasma protein fraction (Plasmanate or Plasmasteril) Plasma protein fraction solutions, also known as human albumin, are similar to albumin solutions. However, in this context, albumin solutions are more commonly used. Plasma protein fraction solutions may be indicated in specific situations, but th

“This fluid will help to decrease your potassium levels which are currently too high.”. Normal Saline does not address high potassium levels; it is used to address hyponatremia and dehydration by increasing sodium levels.

“This fluid will help to lower my potassium levels and replace the fluids I lost from sweating.”. Half Normal Saline is not used to lower potassium levels and is not specifically indicated for treating high potassium. Additionally, it is not typically used to address fluid loss from sweating.

Lactated Ringer's solution is not contraindicated in cases of lactic acidosis. In fact, it contains lactate (28 mEq/L), which can be metabolized to bicarbonate and help correct acidosis.

D10W would not help increase blood pressure. While it can provide hydration, it does not contain medications or components specifically intended to increase blood pressure.

Lethargy is a potential sign of dehydration. When a child is dehydrated, they may become lethargic or unusually tired because their body is not receiving the necessary fluids to function properly. Lethargy can be an early sign of dehydration in children.

Approximately 82 mL/hour is not The correct answer. This calculation does not align with the standard method for calculating fluid replacement in pediatric patients.

Skip monitoring the child's response to treatment. Skipping monitoring is not advisable. Monitoring the child's response to treatment is a critical part of dehydration management. It helps ensure that the child is improving, and adjustments can be made to the treatment plan if necessary.
