What is the most important assessment for the LPN/LVN to perform on a client with a history of chronic obstructive pulmonary disease (COPD) receiving oxygen therapy at 2 liters per minute via nasal cannula?

Correct Answer: B

Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.

Correct Answer: C

Rationale: Having a dental examination every 6 months is crucial for young adult males as it helps in maintaining good oral health and detecting any potential issues early on. Tetanus booster every 10 years is recommended for adults, not every 5 years (Choice A). Herpes zoster immunization is typically recommended for individuals aged 60 and older, not by age 50 (Choice B). While testicular self-examination is important for detecting testicular cancer, routine clinical testicular examinations are not generally needed every 2 years (Choice D). Therefore, the correct answer is to have a dental examination every 6 months.

Correct Answer: B

Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. Kinks in the tubing can lead to urine retention or obstruction, increasing the risk of infection. Changing the catheter every 72 hours is not necessary if there are no signs of infection or other issues. Cleaning the perineal area with antiseptic solution daily is important for hygiene but not the most critical action to prevent infection related to the catheter. Irrigating the catheter with normal saline every shift is not a routine practice and may increase the risk of introducing pathogens into the urinary system.

Correct Answer: D

Rationale: The correct answer is D: 'Clear liquids.' Clients with dysphagia following a stroke are at risk of aspiration, and clear liquids have a higher risk of aspiration compared to thickened liquids or pureed foods. Therefore, the nurse should clarify the prescription for clear liquids to prevent potential harm to the client. Choices A, B, and C are appropriate interventions for a client with dysphagia following a stroke. A dietitian consult can help modify the client's diet for safe swallowing, speech therapy can assist in improving swallowing function, and oral suction at the bedside helps maintain airway patency and prevents aspiration.

Correct Answer: A

Rationale: Performing hand hygiene is essential before any direct patient care procedure to prevent the spread of infection. Proper hand hygiene helps reduce the risk of introducing harmful microorganisms to the client, especially when dealing with a procedure like tracheostomy care. Identifying the client, preparing the sterile field, and donning sterile gloves are all important steps in tracheostomy care, but hand hygiene precedes them to maintain asepsis and ensure patient safety.
