A nurse is assisting with the care of a school-age child who has respiratory failure due to pneumonia. Which of the following positions should the nurse encourage to allow maximal lung expansion?
Prone
Side-lying
Supine
Upright
The Correct Answer is D
Choice A reason: Prone is not the best position to allow maximal lung expansion. Prone is a position where the client lies on their stomach, with their head turned to one side. Prone can help to improve oxygenation in some cases of acute respiratory distress syndrome (ARDS), but it can also increase the risk of pressure ulcers, facial edema, and airway obstruction.
Choice B reason: Side-lying is not the best position to allow maximal lung expansion. Side-lying is a position where the client lies on their side, with their head supported by a pillow. Side-lying can help to prevent aspiration and reduce the work of breathing in some clients, but it can also compromise the ventilation of the dependent lung.
Choice C reason: Supine is not the best position to allow maximal lung expansion. Supine is a position where the client lies on their back, with their head and shoulders slightly elevated. Supine can help to maintain a patent airway and facilitate suctioning in some clients, but it can also increase the risk of atelectasis, pneumonia, and hypoxemia.
Choice D reason: Upright is the best position to allow maximal lung expansion. Upright is a position where the client sits or stands with their back straight and their chest expanded. Upright can help to improve lung compliance, reduce airway resistance, and enhance gas exchange in clients with respiratory failure. Upright can also reduce the pressure on the diaphragm and abdominal organs, and promote the drainage of secretions.

Correct Answer is C
Explanation
Choice A reason: Shaking the inhaler well before using it is a correct action for the client to take, as it helps to mix the medication and the propellant. However, it is not the best answer, as it is a general instruction that applies to most inhalers, not a specific one that indicates an understanding of the teaching.
Choice B reason: Holding the breath for 10 seconds after inhaling the medication is a correct action for the client to take, as it helps to keep the medication in the lungs and improve its absorption. However, it is not the best answer, as it is a general instruction that applies to most inhalers, not a specific one that indicates an understanding of the teaching.
Choice C reason: Rinsing the mouth with water after using the inhaler is the best answer, as it indicates an understanding of the teaching. Rinsing the mouth with water helps to prevent oral thrush, a fungal infection that can occur as a side effect of some inhalers, especially those that contain steroids.
Choice D reason: Waiting 30 seconds between each puff of the inhaler is not a correct action for the client to take, as it can reduce the effectiveness of the medication. The client should wait at least one minute between each puff of the inhaler, unless instructed otherwise by the provider.

Choice B reason: Fat is not detected by the stool guaiac test. The stool guaiac test is a chemical test that reacts with hemoglobin, a protein found in red blood cells. Fat is a lipid that does not contain hemoglobin.
Choice C reason: Parasites are not detected by the stool guaiac test. The stool guaiac test is a chemical test that reacts with hemoglobin, a protein found in red blood cells. Parasites are organisms that live in or on another host and do not contain hemoglobin.
Choice D reason: Blood is detected by the stool guaiac test. The stool guaiac test is a chemical test that reacts with hemoglobin, a protein found in red blood cells.
