Correct Answer: D

Rationale: The correct answer is to use a moisture barrier ointment. This intervention helps protect the skin and promote healing in clients with stage 3 pressure injuries. Cleansing the wound with povidone-iodine solution daily (Choice A) can be too harsh and may delay healing by damaging the surrounding skin. Irrigating the wound with hydrogen peroxide (Choice B) is not recommended as it can be cytotoxic to healing tissue. While repositioning the client every 4 hours (Choice C) is an essential intervention in preventing pressure injuries, it is not directly related to the care of an existing stage 3 pressure injury.

Correct Answer: D

Rationale: The correct action for the nurse to take when caring for a client with deep vein thrombosis is to withhold heparin IV infusion. Administering heparin is crucial in managing deep vein thrombosis by preventing further clot formation. Positioning the affected extremity higher than the heart (Choice A) promotes venous return and reduces swelling. Acetaminophen (Choice B) can be given for pain relief. Massaging the affected extremity (Choice C) is contraindicated as it can dislodge a clot, leading to serious complications.

Correct Answer: C

Rationale: During radiation therapy for breast cancer, one common side effect is skin irritation due to the impact of radiation on the skin cells. This side effect should be closely monitored by the nurse. Fatigue may also occur as a side effect of radiation therapy, but skin irritation is more specific to the treatment area and is a priority in this case. Nausea and weight gain are not typically associated with radiation therapy for breast cancer, making them incorrect choices.

Correct Answer: B

Rationale: The correct answer is B: Mouth sores. Mouth sores are a common side effect of radiation therapy, especially when the treatment is focused on the head or neck area. Weight gain is not typically associated with radiation therapy; instead, clients may experience weight loss due to side effects like nausea and loss of appetite. Hyperpigmentation is not a common finding related to radiation therapy. Increased saliva production is not a typical side effect of radiation therapy; instead, clients may experience dry mouth.

Correct Answer: B

Rationale: Performing a neurological assessment is the appropriate nursing intervention for a patient experiencing a suspected stroke. This assessment helps determine the severity of the stroke, identify potential deficits, and guide further interventions. Administering thrombolytics (Choice A) should only be done after a CT scan to confirm the type of stroke and rule out hemorrhagic stroke. Performing a CT scan (Choice C) is important but is typically done after stabilizing the patient. Administering oxygen (Choice D) is essential to maintain adequate oxygenation, but performing a neurological assessment takes precedence in the immediate management of a suspected stroke.
