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?
- A. Assess the client's respiratory rate and effort.
- B. Measure the client's oxygen saturation level.
- C. Monitor the client's arterial blood gas levels.
- D. Check the client's blood pressure.
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.

The healthcare professional is caring for a client with a chest tube. What is the most important action for the healthcare professional to take to ensure the chest tube is functioning properly?
- A. Milk the chest tube to ensure patency.
- B. Clamp the chest tube when moving the client.
- C. Ensure the water seal chamber is filled to the appropriate level.
- D. Secure the chest tube to the client's bed.
Correct Answer: C
Rationale: Ensuring the water seal chamber is filled to the appropriate level is crucial to maintain the effectiveness of the chest tube drainage system. This step helps prevent air from entering the pleural space, ensuring proper lung re-expansion. 'Milking' the chest tube is not recommended as it can cause damage to the chest tube and surrounding tissues. Clamping the chest tube is not advisable as it can lead to tension pneumothorax. Securing the chest tube to the bed is important for stability but does not directly impact the functioning of the chest tube.
A healthcare professional is preparing to perform denture care for a client. Which of the following actions should the professional plan to take?
- A. Pull down and out at the back of the upper denture to remove.
- B. Brush the dentures with a toothbrush and denture cleaner.
- C. Rinse the dentures with hot water after cleaning them.
- D. Place the dentures in a clean, dry storage container after cleaning them.
Correct Answer: B
Rationale: The correct answer is to brush the dentures with a toothbrush and denture cleaner. This action ensures effective cleaning of the dentures. Dentures should be rinsed with cool or lukewarm water, not hot water, to prevent damage. Placing the dentures in a clean, dry storage container is not the immediate next step after cleaning; they should be kept moist to prevent warping.
Seconal 0.1 gram PRN at bedtime is prescribed to a client for rest. The scored tablets are labeled 1.5 grains per tablet. How many tablets should the LPN/LVN plan to administer?
- A. 0.5 tablet
- B. 1 tablet
- C. 1.5 tablets
- D. 2 tablets
Correct Answer: B
Rationale: To calculate the number of tablets needed, convert the prescribed dose of Seconal from grams to grains. Since 1 gram is equal to approximately 15.43 grains, 0.1 gram is roughly 1.543 grains. Given that each tablet contains 1.5 grains, administering 1 tablet (which is slightly more than the 1.543 grains needed) provides the correct dose of Seconal. Therefore, the LPN/LVN should plan to administer 1 tablet. Choice A (0.5 tablet) is incorrect as it would provide less than the required dose. Choice C (1.5 tablets) and Choice D (2 tablets) are incorrect as they would exceed the necessary dosage.
The nurse is preparing to assist a newly admitted client with personal hygiene measures. The nurse wants to assess the client's gag reflex. Which action should the nurse include?
- A. Offer small sips of water through a straw
- B. Place tongue blade on back half of tongue
- C. Use a penlight to observe back of the oral cavity
- D. Auscultate breath sounds after the client swallows
Correct Answer: B
Rationale: The correct action for the nurse to include when assessing the client's gag reflex is to place a tongue blade on the back half of the tongue. This method effectively tests the gag reflex without causing discomfort. Choice A is incorrect because offering small sips of water through a straw does not assess the gag reflex. Choice C is incorrect as using a penlight to observe the back of the oral cavity does not directly assess the gag reflex. Choice D is incorrect since auscultating breath sounds after the client swallows does not evaluate the gag reflex.
A client has a prescription for 5 units of regular insulin and 10 units of NPH insulin to mix together and administer subcutaneously. Determine the correct order of steps for this procedure.
- A. Inject 5 units of air into the bottle of regular insulin
- B. Withdraw the correct dose of NPH insulin from the bottle
- C. Inject 10 units of air into the bottle of NPH insulin
- D. Withdraw the correct dose of regular insulin from the bottle
Correct Answer: B
Rationale: The correct order of steps for this procedure is to first inject air into the NPH insulin bottle to prevent vacuum formation. After injecting air into the NPH insulin, the next step is to withdraw the correct dose of regular insulin from its bottle. This sequence ensures that the regular insulin is drawn after the NPH insulin, preventing contamination and ensuring accurate dosing. Therefore, choice B is correct. Choices A, C, and D are incorrect because air should be injected into the NPH insulin first, not the regular insulin, and the doses should be withdrawn in the appropriate order to maintain the integrity and potency of each insulin type.
