Nursing Elites

1. Which of the following parameters is the LEAST reliable when assessing the perfusion status of a 2-year-old child?

• A. Capillary refill time
• B. Presence of peripheral pulses
• C. Skin color and temperature
• D. Systolic blood pressure

Correct answer: D

Rationale: Systolic blood pressure is the least reliable parameter when assessing perfusion status in a 2-year-old child. In young children, blood pressure measurements can be variable, affected by factors like anxiety or crying. Capillary refill time, presence of peripheral pulses, and skin color and temperature are more reliable indicators of perfusion status in this age group.

2. The parents of a child hospitalized with asthma who is recovering and is being prepared for discharge are receiving home care instructions from the nurse. Which statement by a parent indicates a need for further instruction?

• A. Coughing spells may be triggered by dust or smoke
• B. Vomiting may occur when our child has coughing episodes
• C. We need to encourage our child to drink fluids
• D. We need to maintain droplet precautions and a quiet environment for at least 2 weeks

Correct answer: D

Rationale: The statement 'We need to maintain droplet precautions and a quiet environment for at least 2 weeks' indicates a need for further instruction. Asthma management does not typically require maintaining droplet precautions. The focus should be on environmental control, medication adherence, and monitoring symptoms rather than droplet precautions, which are more relevant for contagious respiratory infections.

3. Which of the following is a more reliable indicator of perfusion in children than in adults?

• A. Blood pressure
• B. Heart rate
• C. Respiratory rate
• D. Capillary refill

Correct answer: D

Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.

4. How will a ventricular septal defect affect blood flow?

• A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
• B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
• C. No shunting occurs due to high pressure in the left ventricle.
• D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.

Correct answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

5. When inserting an oropharyngeal airway in a small child, what is the preferred method?

• A. Insert the airway with the curvature towards the roof of the mouth and then rotate it 180 degrees.
• B. Insert the airway as you would in an adult, but use an airway that is one size smaller than usual.
• C. Depress the tongue with a tongue blade and insert the airway with the downward curve facing the tongue.
• D. Open the airway with the tongue-jaw lift maneuver and insert the airway until slight resistance is met.

Correct answer: C

Rationale: When inserting an oropharyngeal airway in a small child, it is crucial to depress the tongue with a tongue blade and insert the airway with the downward curve facing the tongue. This technique helps in maintaining an open airway and preventing obstruction by the tongue. Placing the airway with the curve facing the roof of the mouth or using a smaller size is not recommended for small children, as it may not effectively keep the airway patent. The tongue-jaw lift maneuver is not the preferred method for inserting an oropharyngeal airway in small children.
