Correct Answer: A

Rationale: The correct answer is to use tracheostomy covers when going outdoors. This instruction is important as it helps protect the airway from dust and other particles, reducing the risk of infection or irritation. Choice B is incorrect because maintaining sterile technique is crucial during tracheostomy care to prevent infections, but it is not the most pertinent instruction in this scenario. Choice C is incorrect as removing the outer cannula is not a routine cleaning procedure and should only be done by healthcare professionals when necessary. Choice D is incorrect because cleaning around the stoma with normal saline is not recommended as it can cause irritation to the skin and stoma site.

Correct Answer: C

Rationale: Fluid-volume deficit causes tachycardia. With correction of the imbalance, the heart rate should return to the expected range. An increase in hematocrit (Choice A) would indicate hemoconcentration, not a successful fluid replacement. An increase in respiratory rate (Choice B) could indicate respiratory distress or hypoxia, not improvement in fluid volume status. A decrease in capillary refill time (Choice D) may indicate improved peripheral perfusion but is not a direct indicator of fluid replacement success.

Correct Answer: D

Rationale: The correct answer is D because maturational loss is related to developmental changes, such as children leaving for college. This type of loss is tied to the normal life transitions of individuals and can lead to feelings of grief and adjustment. Choices A, B, and C represent different types of losses. Choice A involves a traumatic loss of a child due to illness, choice B involves a financial loss impacting the head of household's job, and choice C involves a material loss due to a fire incident. While these losses are significant, they do not specifically relate to maturational loss, which is associated with expected life stage transitions.

Correct Answer: D

Rationale: The correct answer is to change the administration set every 72 to 96 hours. This practice helps reduce the risk of infection by preventing the build-up of bacteria in the tubing. Changing the set too frequently (choices A, B, and C) may increase the chances of contamination and infection without providing additional benefits. Therefore, the LPN should follow the guideline of changing the administration set every 72 to 96 hours to maintain the client's safety during the continuous intravenous normal saline infusion.

Correct Answer: A

Rationale: The correct answer is 'Assessment.' In the nursing process, assessment is the first step, crucial before any intervention. Assessment involves gathering data about the client's condition to establish a baseline for evaluating responses to interventions. In this scenario, the newly licensed nurse missed assessing the client's pain intensity, location, quality, and other relevant factors before administering the pain medication. While the follow-up evaluation with the client is commendable, it cannot replace the initial assessment. Planning involves setting goals and outcomes, intervention is the action taken to achieve these goals, and evaluation assesses the client's response to the intervention.
