As part of primary cancer prevention program, an oncology nurse answers questions from the public at health fair. When someone asks about the laryngeal cancer, the nurse should explain that:

Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. Laryngeal cancer is strongly linked to smoking and alcohol consumption. 2. Both smoking and alcohol use are modifiable risk factors, meaning they can be prevented. 3. By avoiding smoking and excessive alcohol intake, individuals can significantly reduce their risk of developing laryngeal cancer. 4. Therefore, laryngeal cancer is considered one of the most preventable types of cancer. Summary of why the other choices are incorrect: B. Inhaling polluted air can be a risk factor for laryngeal cancer, so this statement is inaccurate. C. Laryngeal cancer occurs more frequently in men than women, so this statement is incorrect. D. Squamous cell carcinoma, not adenocarcinoma, is the most common type of laryngeal cancer, making this statement incorrect.

Correct Answer: C

Rationale: The correct answer is C. Aling Maria is admitted for myxedema, which is severe hypothyroidism. Symptoms of hypothyroidism include lethargy, weight gain, slow speech, and decreased respiratory rate. Bradycardia, weight loss, heart failure, and diarrhea are not typical symptoms of myxedema. Tachycardia, constipation, and exopthalmus are more commonly associated with hyperthyroidism. Hypothermia, weight loss, and increased respiratory rate are not consistent with myxedema. Thus, choice C is the most appropriate initial assessment for Aling Maria.

Correct Answer: D

Rationale: The correct answer is D because it involves collaboration with the client to validate the identified health problem. By asking the client directly if they agree that fatigue is a problem for them, it promotes client-centered care and empowers the client in their own care. Choice A is incorrect as it assumes the nurse's assessment is enough to confirm fatigue. Choice B is incorrect as it focuses on the nurse's analysis rather than the client's experience. Choice C is incorrect because it is a closed-ended question that may not encourage open communication or validation from the client.

Correct Answer: B

Rationale: The correct answer is B. Polymyositis can affect muscles involved in swallowing, leading to aspiration risk. Therefore, it's crucial for the client to exhibit no signs or symptoms of aspiration. Choice A is unrelated to polymyositis. Choice C involves issues with muscle weakness rather than aspiration risk. Choice D relates to cognitive function, not a common issue with polymyositis.

Correct Answer: D

Rationale: The correct answer is D: Involve the son in the plan of care as much as possible. This is important for several reasons. Firstly, involving the son promotes family-centered care, which can improve patient outcomes. Secondly, the son may provide valuable insights into the patient's preferences and needs. Thirdly, it can help reduce the patient's confusion by providing familiar support. Option A is incorrect as it disregards the potential benefits of involving family members. Option B is incorrect as it focuses on the patient's rest without considering the emotional support the son may provide. Option C is incorrect as it assumes the gender of the family member matters more than their relationship to the patient.

Correct Answer: C

Rationale: The correct answer is C: "Divided doses produce greater cytotoxic effects on the diseased cells." Dividing the doses of the antimetabolite allows for more consistent levels of the drug in the bloodstream, ensuring sustained exposure to the cancer cells. This continuous exposure enhances the drug's cytotoxic effects, increasing its efficacy in targeting and destroying the diseased cells. Options A and B provide vague or incorrect information, while option D is misleading as antimetabolites do not prevent cell division, but rather disrupt DNA synthesis.

Correct Answer: B

Rationale: The correct answer is B: Clonidine (Catapres). Clonidine is known to cause headache as a side effect due to its mechanism of action affecting blood pressure regulation in the brain. Furosemide (A) is a diuretic that typically causes electrolyte imbalances, not headaches. Atenolol (C) is a beta-blocker used for hypertension, which can cause fatigue but not typically headaches. Adalat (D) is a calcium channel blocker that usually causes peripheral edema, not headaches.

Correct Answer: A

Rationale: The correct answer is A. Prednisone is a corticosteroid that can cause adverse reactions such as increased weight due to fluid retention, hypertension due to sodium retention, and insomnia due to its stimulating effects. Vaginal bleeding, jaundice, inflammation, stupor, breast lumps, pain, dyspnea, numbness, and headache are not commonly associated with prednisone use. Monitoring for weight changes, blood pressure, and sleep patterns is essential when administering prednisone to a client with rheumatoid arthritis for early detection and management of adverse reactions.

Correct Answer: A

Rationale: The correct answer is A because hyperparathyroidism is not caused by increased levels of thyroxine but by overactivity of the parathyroid glands. This would lead to symptoms of heat intolerance due to increased metabolism and systolic hypertension due to the effects of excess parathyroid hormone on calcium levels. Choice B is incorrect because diastolic hypertension and widened pulse pressure are not typical symptoms of hyperparathyroidism. Choice C is incorrect because weight gain is not a common symptom of hyperparathyroidism. Choice D is incorrect because anorexia and hyper-excitability are not typical symptoms of hyperparathyroidism.
