Correct Answer: C

Rationale: The correct answer is C: Obtaining and charting daily weight. Monitoring daily weight is crucial in identifying the onset of dehydration as weight loss can be an early sign. Measuring abdominal girth (choice A) is not the most reliable method for detecting dehydration. Converting ounces to milliliters (choice B) and selecting food items with high water content (choice D) may be important for overall hydration but are not the most critical interventions for identifying the onset of dehydration.

Correct Answer: C

Rationale: Ensuring the safety of a blood transfusion is crucial to prevent potential errors or adverse reactions. Checking the blood identification numbers with the laboratory technician at the Blood Bank when the blood is dispersed helps confirm that the correct blood product is being administered to the right patient, reducing the risk of transfusion reactions. The other choices are incorrect because asking the client to say and spell their full name (Choice A) is a part of the identification process but not specific to ensuring the safety of the blood transfusion. While having another qualified healthcare professional check the unit (Choice B) is a good practice, the direct verification with the Blood Bank technician is a more critical step in ensuring the correct blood product is administered. Choice D is irrelevant to ensuring the safety of the blood transfusion as it addresses infection control measures.

Correct Answer: C

Rationale: The correct answer is to assess the pulse and blood pressure. Distended neck veins can indicate fluid volume overload or heart failure, which can lead to hemodynamic instability. Assessing the pulse and blood pressure will provide immediate information on the client's cardiovascular status. Documenting the observation in the chart (choice A) is important but not the priority when immediate assessment is needed. Measuring urine specific gravity and volume (choice B) is important for assessing renal function but is not the priority in this situation. Assessing the client's deep tendon reflexes (choice D) is not relevant to addressing distended neck veins in a client sitting to eat.

Correct Answer: D

Rationale: The correct action for the nurse to take when a client finds antiembolism stockings uncomfortably tight is to teach the client the purpose of wearing the stockings. This educates the client on the importance of the stockings in preventing blood clots and encourages compliance. Removing the stockings or pulling them down may compromise their effectiveness. Measuring the client's calf size is not necessary in this situation as the discomfort is due to tightness, not incorrect sizing.

Correct Answer: D

Rationale: The correct answer is 'My rings seem to be tighter this week.' This assessment finding indicates possible fluid retention, which can be a sign of fluid or electrolyte imbalance in an older adult. Choices A, B, and C do not specifically point towards fluid or electrolyte imbalance. Feeling cold, increased urination with coffee consumption, and feeling thirsty in the summer are not direct indicators of fluid or electrolyte imbalance in this context.
