1. Hormonal agents are used to treat some cancers. An example is:

A. thyroxine to treat thyroid cancer.
B. ACTH to treat adrenal carcinoma.
C. estrogen antagonists to treat breast cancer.
D. glucagon to treat pancreatic carcinoma.

Correct answer: C

Rationale: Estrogen antagonists are commonly used to treat estrogen hormone-dependent cancers such as breast carcinoma. One well-known estrogen antagonist used in breast cancer therapy is Tamoxifen (Nolvadex). This drug, in combination with surgery and other chemotherapeutic drugs, reduces breast cancer recurrence by 30%. Estrogen antagonists can also be administered to prevent breast cancer in women who have a strong family history. Thyroxine is a thyroid hormone used to treat hypothyroidism, not thyroid cancer. ACTH is an anterior pituitary hormone that stimulates the adrenal glands to release glucocorticoids; it does not treat adrenal cancer. Glucagon is a pancreatic alpha cell hormone that stimulates glycogenolysis and gluconeogenesis; it does not treat pancreatic cancer.

2. Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?

A. They have a high energy-to-fluid-volume ratio.
B. Even though hypertonic, they are well tolerated.
C. They are a basic solution due to the addition of sodium hydroxide (NaOH).
D. The pH is alkaline, making them compatible with most medications.

Correct answer: A

Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.

3. A 26-year-old single woman is knocked down and robbed while walking her dog one evening. Three months later, she presents at the crisis clinic, stating that she cannot put this experience out of her mind. She complains of nightmares, extreme fear of being outside or alone, and difficulty eating and sleeping. What is the best response by the nurse?

A. "I will ask the physician to prescribe medication for you."?
B. "That must have been a very difficult and frightening experience. It might be helpful to talk about it."?
C. "In the future, you might walk your dog in a more populated area or hire someone else to take over this task."?
D. "Have you thought of moving to a safer neighborhood?"?

Correct answer: B

Rationale: Choice B is the best response as it provides empathy and encourages the client to talk about her experience, which can be therapeutic. This approach validates the client's feelings and offers support. By acknowledging the difficulty and fear experienced by the client, the nurse opens the door for the client to express her emotions and begin the process of coping with the trauma. Choices A, C, and D do not address the emotional impact of the traumatic event or provide an opportunity for the client to express her feelings and concerns. Choice A immediately jumps to medication without exploring other supportive interventions. Choice C focuses on practical solutions without addressing the client's emotional needs. Choice D suggests a drastic solution without considering the client's emotional state or preferences.

4. The nurse is preparing a client for surgery. Which item is most important to remove before sending the client to surgery?

A. Hearing aid
B. Contact lenses
C. Wedding ring
D. Artificial eye

Correct answer: B

Rationale: The correct answer is B: Contact lenses. It is crucial to remove contact lenses before surgery to prevent corneal drying, especially with non-extended wear lenses. Leaving the hearing aid or artificial eye in place does not pose harm to the client during surgery. While wedding rings are typically covered with tape, leaving them on is acceptable. Therefore, choices A, C, and D are incorrect in this scenario.

5. A twenty-one-year-old man suffered a concussion, and the MD ordered an MRI. The patient asks, 'Will they allow me to sit up during the MRI?' The correct response by the nurse should be:

A. "I will have to talk to the doctor about letting you sit upright during the test."?
B. "You will be positioned in the reverse Trendelenburg position to maximize the view of the brain."?
C. "The radiologist will let you know."?
D. "You will have to lie down on your back during the test."?

Correct answer: D

Rationale: The correct answer is to inform the patient that they will have to lie down on their back during the MRI. This positioning is necessary for the scan to obtain accurate images of the brain. Choice A is incorrect because the decision on the positioning during the MRI is typically determined by the imaging protocol and not subject to negotiation during the test. Choice B is incorrect as the reverse Trendelenburg position is not commonly used during MRI scans. Choice C is incorrect because the radiologist does not usually make decisions on patient positioning during the MRI; it is predetermined by the imaging requirements.
