Question 1 of 5

What is the most important postoperative instruction the nurse must give a client who has just returned from the operating room after receiving a subarachnoid block?

Correct Answer: D

Rationale: The correct answer is D: “Remain supine for the time specified by the physician.” After a subarachnoid block, the client must remain lying down to prevent complications like spinal headaches due to cerebrospinal fluid leakage. This position helps maintain adequate spinal fluid pressure. Choice A is incorrect as fluid intake is important postoperatively. Choice B is not relevant to a subarachnoid block. Choice C is important but not the most crucial instruction compared to maintaining the supine position.

Question 2 of 5

A client is undergoing a diagnostic workup for suspected thyroid cancer. What is the most common form of thyroid cancer in adults?

Correct Answer: D

Rationale: The correct answer is D: Papillary carcinoma. This is the most common form of thyroid cancer in adults, accounting for about 80% of cases. It is typically slow-growing and has a good prognosis. Papillary carcinoma arises from the follicular cells of the thyroid gland. Follicular carcinoma (choice A) is less common than papillary carcinoma and arises from the follicular cells as well. Anaplastic carcinoma (choice B) is a highly aggressive and rare form of thyroid cancer. Medullary carcinoma (choice C) originates from the parafollicular C cells of the thyroid gland and is not as common as papillary carcinoma. Therefore, the most appropriate choice is D, papillary carcinoma, due to its high prevalence and relatively favorable prognosis.

Question 3 of 5

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: The correct answer is A: Laryngeal cancer is one of the most preventable types of cancer. This is because the primary risk factors for laryngeal cancer are largely related to lifestyle choices such as smoking, excessive alcohol consumption, and exposure to certain occupational hazards. By avoiding these risk factors, individuals can significantly reduce their chances of developing laryngeal cancer. Choices B, C, and D are incorrect: B: Inhaling polluted air isn’t a risk factor for laryngeal cancer - This is incorrect as exposure to polluted air can contribute to the development of laryngeal cancer. C: Laryngeal cancer occurs primarily in women - This is incorrect as laryngeal cancer occurs more frequently in men than in women. D: Adenocarcinoma accounts for most cases of laryngeal cancer - This is incorrect as squamous cell carcinoma is the most common type of laryngeal cancer, not adenocarcin

Question 4 of 5

To combat the most common adverse effects of chemotherapy, the nurse would administer an:

Correct Answer: A

Rationale: The correct answer is A: Antiemetic. Chemotherapy commonly causes nausea and vomiting as adverse effects. Antiemetics are medications specifically designed to prevent or alleviate nausea and vomiting. Administering an antiemetic helps manage these side effects and improve the patient's quality of life during chemotherapy. Antibiotics (B) are used to treat bacterial infections, not chemotherapy side effects. Antimetabolites (C) are a type of chemotherapy drug, not used to combat its side effects. Anticoagulants (D) are used to prevent blood clots and are not indicated for managing chemotherapy side effects like nausea and vomiting.

Question 5 of 5

A client is undergoing a diagnostic work-up for suspected testicular cancer. When obtaining the client’s history, the nurse checks for known risk factors for this type of cancer. Testicular cancer has been linked to:

Correct Answer: D

Rationale: The correct answer is D: Cryptorchidism. Cryptorchidism, also known as undescended testicle, is a known risk factor for testicular cancer as the testicle does not descend into the scrotum during fetal development, increasing the risk of cancer development. Testosterone therapy during childhood (A) and early onset of puberty (B) are not directly linked to testicular cancer. Sexually transmitted diseases (C) typically do not increase the risk of testicular cancer. Therefore, choice D is the most relevant risk factor for testicular cancer in this scenario.
