What instructions should the nurse give to a patient with cervical cancer who is planned to receive external-beam radiation to prevent complications from the effects of the radiation?

Correct Answer: C

Rationale: The correct answer is C: Clean the perianal area carefully after every bowel movement. This is important to prevent skin breakdown and infection due to the potential side effect of radiation-induced diarrhea. By maintaining good hygiene in the perianal area, the patient can reduce the risk of complications such as skin irritation and infection. Choice A is incorrect because testing stools for the presence of blood is not directly related to preventing complications from external-beam radiation. Choice B is incorrect because while a high-residue, high-fiber diet may be beneficial for some cancer patients, it is not specifically recommended to prevent complications from radiation therapy in this case. Choice D is incorrect because inspecting the mouth and throat daily for thrush is more relevant for patients receiving chemotherapy or immunosuppressive therapy, not specifically for those undergoing external-beam radiation.

Correct Answer: D

Rationale: The correct answer is D: Encourage fluid intake up to 4000 mL every day. High calcium levels can lead to dehydration, so encouraging fluid intake helps prevent this complication. Increased fluid intake also promotes calcium excretion through urine. Bed rest (A) is not directly related to managing high calcium levels. Auscultating lung sounds (B) every 4 hours is more relevant for respiratory issues. Monitoring for Trousseau's and Chvostek's signs (C) is associated with low calcium levels, not high levels.

Correct Answer: C

Rationale: The correct answer is C: Avoid exposing the treated area to sunlight. This is important because radiation therapy can make the skin more sensitive to sunlight, leading to increased risk of sunburn and skin damage. Sun exposure can worsen skin reactions and delay healing. Choice A is incorrect because heat sources like heating pads can exacerbate skin irritation. Choice B is incorrect as alcohol-based lotions can further irritate the skin. Choice D is incorrect as hot water and strong soap can be too harsh on the sensitive skin. Overall, protecting the treated area from sunlight is crucial for optimal skin care during radiation therapy.

Correct Answer: A

Rationale: The correct answer is A: Administer regular insulin intravenously. In DKA, the priority is to lower blood glucose levels and correct acidosis. Regular insulin intravenously is the fastest way to reduce blood glucose levels. Oral hypoglycemic agents (B) are not effective in DKA. Sodium bicarbonate (C) is not routinely recommended in DKA as it may worsen acidosis. Providing a high-calorie diet (D) is not appropriate as the focus should be on treating the underlying condition first.

Correct Answer: B

Rationale: The correct answer is B: Avoid intramuscular injections. Thrombocytopenia is a condition characterized by low platelet count, which can lead to impaired blood clotting. Intramuscular injections can cause bleeding and bruising due to the decreased ability of blood to clot. Therefore, it is crucial to avoid invasive procedures like intramuscular injections to prevent excessive bleeding in patients with thrombocytopenia. Encouraging light exercise (choice A) can be beneficial for overall health but may not directly address the risk of bleeding. Avoiding aspirin (choice C) is important as it can further increase the risk of bleeding. Using a soft toothbrush for oral care (choice D) is a good practice, but it does not directly address the risk associated with intramuscular injections in patients with thrombocytopenia.
