A client is undergoing a diagnostic workup for suspected thyroid cancer. What is the most common form of thyroid cancer in adults?
- A. Follicular carcinoma
- B. Anaplastic carcinoma
- C. Medullary carcinoma
- D. Papillary carcinoma
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.

Nursing assessment for a patient with metabolic alkalosis includes evaluation of laboratory data for all of the following except:
- A. Hypocalcemia
- B. Hypokalemia
- C. Hypoglycemia
- D. Hypoxemia
Correct Answer: C
Rationale: The correct answer is C: Hypoglycemia. In metabolic alkalosis, the blood pH is elevated due to an excess of bicarbonate. Hypoglycemia is not directly related to metabolic alkalosis but can be seen in other conditions like diabetes or fasting. Evaluating for hypocalcemia (A) is important as alkalosis can lead to decreased ionized calcium levels. Hypokalemia (B) is common in metabolic alkalosis due to potassium loss. Hypoxemia (D) is not directly related to metabolic alkalosis but can occur in severe cases due to respiratory compensation. Therefore, hypoglycemia is the least relevant in assessing metabolic alkalosis.
One of the complications of prolonged bed rest is decubitus ulcer. Which of the following can best prevent its occurrence?
- A. Massage reddened areas with lotion or oils
- B. Use special water mattress
- C. Turn frequently every 2 hours
- D. Keep skin clean and dry
Correct Answer: C
Rationale: The correct answer is C: Turn frequently every 2 hours. This helps redistribute pressure, preventing constant pressure on one area and reducing the risk of developing pressure ulcers. Turning every 2 hours promotes circulation and relieves pressure points.
A: Massaging reddened areas can worsen the condition by increasing friction and pressure.
B: While a special water mattress can help in preventing pressure ulcers, turning frequently is more effective.
D: Keeping the skin clean and dry is important for overall skin health but may not directly prevent pressure ulcers.
A clinical nurse specialist (CNS) is orienting a new graduate registered nurse to an oncology unit where blood product transfusions are frequently administered. In discussing ABO compatibility, the CNS presents several hypothetical scenarios. A well-informed new graduate would know the greatest likelihood of an acute hemolytic reaction would occur when giving:
- A. A-positive blood to an A-negative client
- B. O-positive blood to an A-positive client
- C. O-negative blood to an O-positive client
- D. B-positive blood to an AB-positive client
Correct Answer: A
Rationale: The correct answer is A: A-positive blood to an A-negative client. This is because in ABO blood typing, individuals with blood type A have anti-B antibodies in their plasma. Therefore, if A-positive blood (which contains the A antigen) is given to an A-negative client (who has anti-A antibodies), there is a high risk of an acute hemolytic reaction due to the antibodies attacking the transfused blood cells.
Choices B, C, and D are incorrect because they do not involve a mismatch of ABO blood types that would lead to a significant risk of acute hemolytic reaction. In choice B, O-positive blood can be safely transfused to an A-positive client as O blood is considered the universal donor. In choice C, O-negative blood can be safely given to an O-positive client as O-negative blood is compatible with all blood types. In choice D, B-positive blood can be safely administered to an AB-positive client as the AB blood type can receive both
After reviewing the database, the nurse discovers that the patient’s vital signs have not been recorded by the nursing assistive personnel (NAP). Which clinical decision should the nurse make? Administer scheduled medications assuming that the NAP would have reported
- A. abnormal vital signs. Have the patient transported to the radiology department for a scheduled x-ray, and
- B. review vital signs upon return.
- C. Ask the NAP to record the patient’s vital signs before administering medications.
- D. Omit the vital signs because the patient is presently in no distress.
Correct Answer: C
Rationale: The correct answer is C. The nurse should ask the NAP to record the patient's vital signs before administering medications. This is important for ensuring patient safety and monitoring any potential changes in the patient's condition. By having the NAP record the vital signs, the nurse can assess the patient's current status and make informed decisions regarding medication administration.
Option A is incorrect because administering medications without knowing the patient's vital signs, especially if they are abnormal, can be risky. Option B is not the best choice as it delays addressing the missing vital signs. Option D is incorrect as omitting vital signs assessment is not in line with best practices for patient care.
Many neuromuscular disorders can impair respiratory function. What intervention can a home care nurse recommend to help prevent complications in patients with impaired respiratory function?
- A. Antibiotics as needed
- B. Bedrest
- C. Elevate the head of bed
- D. Suction q4h
Correct Answer: C
Rationale: The correct answer is C: Elevate the head of bed. Elevating the head of the bed helps improve lung expansion and ventilation, making it easier for patients with impaired respiratory function to breathe. This position also helps prevent aspiration and reduces the risk of respiratory complications. Antibiotics (choice A) are not indicated unless specifically prescribed for an infection. Bedrest (choice B) can lead to deconditioning and worsen respiratory function. Suctioning (choice D) every 4 hours is not necessary unless there is excessive secretions present.
