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?

Choice A reason: Donning sterile gloves is an essential step to prevent contamination and infection during the insertion of an indwelling urinary catheter. The nurse should also use aseptic technique and a sterile catheter kit.

Choice B reason: Applying an oil-based lubricant to the indwelling urinary catheter is not recommended, as it can damage the latex material and increase the risk of catheter-associated urinary tract infection (CAUTI). The nurse should use a water-soluble lubricant instead.

Choice C reason: Testing the balloon on the indwelling urinary catheter before insertion is a good practice, as it ensures that the balloon is functioning properly and does not leak or burst. The nurse should inflate and deflate the balloon with sterile water or saline using a syringe.

Choice D reason: Using one cotton swab to clean the client's urinary meatus is not sufficient, as it may not remove all the bacteria and debris. The nurse should use at least three cotton swabs and clean the meatus from front to back in a circular motion. The nurse should also use an antiseptic solution such as chlorhexidine or povidone-iodine.

Choice A reason: Crackles auscultated over the client's lung fields are not a sign of pleural effusion. Crackles are abnormal breath sounds that indicate fluid or secretions in the alveoli. They can be heard in conditions such as pneumonia, heart failure, or pulmonary edema.

Choice B reason: Crepitus palpated on the client's chest is not a sign of pleural effusion. Crepitus is a crackling sensation that occurs when air leaks into the subcutaneous tissue. It can be felt in conditions such as pneumothorax, chest trauma, or chest surgery.

Choice C reason: Substernal retractions noted on the client's chest are not a sign of pleural effusion. Substernal retractions are inward movements of the chest wall below the sternum that indicate increased respiratory effort. They can be seen in conditions such as asthma, bronchiolitis, or croup.

Choice D reason: Dullness percussed over the client's lung fields is a sign of pleural effusion. Dullness is a flat sound that indicates the presence of a solid or liquid mass in the thoracic cavity. It can be detected in conditions such as pleural effusion, atelectasis, or consolidation.
