A client has applied a cold pack to their arm to help decrease swelling and inflammation after an injury. Which of the following signs indicates that the cold pack should be removed?

Correct Answer: A

Rationale: When using a cold pack for therapeutic purposes, it is essential to monitor the site to prevent tissue damage. Prolonged use of cold therapy can lead to pale, mottled skin with a bluish appearance. This change in skin color indicates poor circulation, and the cold pack should be removed immediately to prevent tissue injury. Choices B, C, and D are incorrect because the duration of cold pack application, client complaints of nausea, and capillary refill time do not specifically indicate the need for the cold pack to be removed due to potential tissue damage.

Correct Answer: C

Rationale: When caring for a client requiring droplet precautions, it is essential for the nurse to wear a mask when within 3 feet of the client. This practice helps prevent the transmission of droplet particles that may be produced when the client coughs or sneezes. Assigning the client to a negative-pressure room is not typically necessary for droplet precautions unless specifically indicated for airborne precautions. Using sterilized equipment when sharing between clients with pertussis is important for infection control but does not directly relate to droplet precautions. Therefore, the correct action to uphold droplet precautions in this scenario is to wear a mask when coming within close proximity to the client.

Correct Answer: D

Rationale: Parents of newborn infants should use an approved car seat that has been installed facing backward in the back seat of the car. Securing infants in car seats, even from the first ride home from the hospital, promotes safety while transporting. While safety measures at home such as baby gates or outlet covers are important, they are not the priority safety measures until the baby is old enough to be mobile. The car seat is crucial for protecting the newborn during transportation, ensuring proper positioning and restraint in the event of sudden stops or accidents. Turning handles of pans on the stove inward, setting up a baby gate, and covering electrical outlets are important safety measures at home but are not as critical for the immediate safety of a newborn during transportation.

Correct Answer: B

Rationale: The correct answer is 'Nausea, vomiting, seizures.' Carbon monoxide poisoning can present with symptoms such as headache, dizziness, weakness, nausea, vomiting, and confusion. Severe cases can progress to seizures, coma, and even death. It is crucial for healthcare providers to recognize these symptoms promptly to initiate appropriate treatment. Choices A, C, and D are incorrect because a red rash, flushing of the face and neck, and abdominal pain radiating to the back are not typically associated with carbon monoxide poisoning. It is essential to be aware of the common manifestations of carbon monoxide poisoning to ensure timely intervention and prevent adverse outcomes.

Correct Answer: C

Rationale: Feeling a tingling sensation when touching an electrical cord is a warning sign that the device may be malfunctioning. This sensation indicates a potential electrical current leak, which could pose a risk of harm. The correct action is to immediately discontinue the use of the device and send it to the maintenance department for inspection. Continuing to use the device without addressing the issue could lead to electric shock or fire hazards. Trying to plug the device into a different outlet does not address the underlying problem of potential device malfunction. Notifying the supervisor about the risk of an electrical fire is important, but the immediate action should be to stop using the device and have it inspected by maintenance professionals. Therefore, the best course of action is to discontinue the device and ensure it is checked thoroughly before further use.
