Correct Answer: A

Rationale: The correct way to assess for pitting edema is to press over a bony area, typically the tibia, for 5 seconds and then release. This allows for the identification of pitting edema, characterized by an indentation that persists for a few seconds. Choice B is incorrect as pitting edema assessment does not involve checking for discoloration. Choice C is incorrect as the presence of a rash is not indicative of pitting edema. Choice D is incorrect as rebound tenderness is a different assessment used for abdominal conditions, not for pitting edema.

Correct Answer: A

Rationale: The correct answer is to insert a chest tube. In managing a patient with a suspected pneumothorax, the priority is to relieve the pressure from the pneumothorax by inserting a chest tube. Monitoring respiratory status (choice B) is important but comes after ensuring proper management of the pneumothorax. Administering oxygen (choice C) can help support oxygenation but does not address the underlying issue of pressure in the thoracic cavity. Calling for assistance (choice D) can be done concurrently with managing the pneumothorax, but the immediate intervention to address the pneumothorax itself is chest tube insertion.

Correct Answer: B

Rationale: The correct answer is to ensure oxygen tanks are kept upright at all times. This is important to prevent the tanks from falling over, which can lead to injuries or tank damage. Choice A is incorrect because oxygen tanks should not be stored in a closet when not in use, as this can lead to poor ventilation and potential hazards. Choice C is incorrect because smoking near oxygen tanks poses a significant fire risk. Choice D is incorrect because while it is important to keep oxygen equipment away from heat sources, ensuring the tanks are kept upright is a more critical safety measure.

Correct Answer: B

Rationale: The correct instruction the nurse should reinforce with the client undergoing radiation therapy is to avoid using perfumed lotions. This is essential to reduce the risk of skin irritation, as perfumed lotions can exacerbate skin reactions during radiation therapy. Applying sunscreen before going outside is generally a good practice but not specifically related to radiation therapy. Massaging the area daily is contraindicated during radiation therapy as it can further irritate the skin. Taking vitamin supplements with food is important for overall health but is not a specific instruction related to radiation therapy.

Correct Answer: A

Rationale: The correct answer is A: Inspection, Palpation, Percussion, Auscultation. A focused respiratory assessment involves inspecting the chest for any abnormalities, palpating to assess tenderness and chest expansion, percussion to evaluate underlying structures, and auscultation to listen to lung sounds. Choice B is incorrect because observation is generally part of inspection, not a separate component. Choice C is incorrect as auscultation should come before percussion in a respiratory assessment. Choice D is incorrect because inspection should precede palpation in a structured assessment.
