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.

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 C: Prothrombin time (PT) of 30 seconds. A low potassium level (choice A) and an elevated INR (choice B) indicate potential bleeding risks during surgery. A positive pregnancy test (choice D) in a female client can lead to complications during surgery. However, a Prothrombin time of 30 seconds is within the normal range and does not contraindicate the client from having surgery as scheduled.

Correct Answer: A

Rationale: The correct answer is 'Airborne.' Varicella (chickenpox) is caused by the varicella-zoster virus, which spreads through the air by respiratory droplets. Therefore, placing the client on airborne precautions is necessary to prevent the transmission of the virus. Choice B, 'Standard precautions,' involve basic infection prevention measures that are used for all client care. Choice C, 'Contact precautions,' are used for diseases that spread by direct or indirect contact. Choice D, 'Droplet precautions,' are implemented for diseases transmitted by respiratory droplets that are larger than 5 microns.

Correct Answer: D

Rationale: For a client with epilepsy, it is essential to avoid restraining them with strict bed rest as it can lead to complications like muscle atrophy, thrombosis, and pressure ulcers. Having suction equipment at the bedside is important in case of seizures to prevent aspiration. Keeping bed rails up can prevent falls during a seizure. Ensuring that the client has IV access is crucial for administering medications such as antiepileptic drugs or emergency medications if needed. Therefore, maintaining the client on strict bed rest is not a recommended precaution for a client with epilepsy.
