A client with a history of chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute via nasal cannula. The client is short of breath and has a pulse oximetry reading of 88%. What action should the LPN take first?

Correct Answer: B

Rationale: Repositioning the client to a high Fowler's position should be the first action taken by the LPN. This position helps improve oxygenation by maximizing lung expansion, making it easier for the client to breathe. Increasing the oxygen flow rate without addressing positioning may not fully optimize oxygen delivery. Notifying the healthcare provider should come after immediate interventions. Encouraging pursed-lip breathing is beneficial but should follow the initial positioning to further assist the client in managing their breathing difficulty.

Correct Answer: B

Rationale: The correct answer is B: Increased urine output. In diabetes insipidus, there is a deficiency of antidiuretic hormone (ADH), leading to the excretion of large amounts of dilute urine. Reporting increased urine output is crucial as it is a hallmark sign of diabetes insipidus. Weight gain (choice A) is not typically associated with diabetes insipidus; instead, clients may experience weight loss due to fluid loss. Low blood pressure (choice C) can be a complication of diabetes insipidus due to dehydration from excessive urination, but the priority finding to report is the increased urine output. Thirst (choice D) is a common symptom of diabetes insipidus due to the body's attempt to compensate for fluid loss, but it is not the most critical finding to report.

Correct Answer: B

Rationale: In a client with septicemia, decreased blood pressure is a critical finding that suggests potential septic shock, a life-threatening condition. Septic shock requires immediate medical intervention to prevent further deterioration and organ dysfunction. Increased urine output (Choice A) may indicate adequate fluid resuscitation, which is a positive response. Increased heart rate (Choice C) and increased respiratory rate (Choice D) are common physiological responses to sepsis and do not necessarily indicate immediate life-threatening complications like decreased blood pressure does in septic shock.

Correct Answer: D

Rationale: The inner forearm is the most appropriate site for administering a tuberculin skin test. This test requires an intradermal injection, which is administered just below the surface of the skin. The inner forearm provides a flat, easily accessible surface for this type of injection. Choices A, B, and C are incorrect because the tuberculin skin test should not be administered into a muscle (deltoid muscle or vastus lateralis muscle) or into the abdomen. The test requires precise placement within the dermal layer of the skin on the inner forearm to accurately assess for a reaction.

Correct Answer: D

Rationale: The correct answer is D: Blood glucose. Monitoring blood glucose levels is crucial for clients receiving total parenteral nutrition (TPN) due to the high glucose content in TPN solutions. TPN delivers essential nutrients, including glucose, directly into the bloodstream. Clients on TPN are at risk of developing hyperglycemia due to the concentrated glucose infusion. Therefore, close monitoring of blood glucose levels is necessary to detect and prevent hyperglycemia-related complications such as osmotic diuresis, hyperosmolarity, and electrolyte imbalances. While serum sodium, serum calcium, and blood urea nitrogen (BUN) levels are important parameters in various clinical scenarios, they are not specifically associated with TPN administration. These values are not the primary indicators to assess for complications in clients receiving TPN.
