Nursing Elites

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. Which of the following post-operative diets is most appropriate for the client who has had a hemorrhoidectomy?

• A. High-fiber
• B. Low-residue
• C. Bland
• D. Clear-liquid

Correct answer: D

Rationale: The correct answer is 'Clear-liquid.' After a hemorrhoidectomy, the client is usually started on a clear-liquid diet to allow the intestines to rest and promote healing. This diet helps prevent straining during bowel movements, which is crucial for recovery. Stool softeners are often included in the plan to avoid constipation. Once the client tolerates the clear liquids well, they can progress to a regular diet. High-fiber diet (choice A) is beneficial in the later stages of recovery to prevent constipation but is not typically the initial post-operative diet. Low-residue diet (choice B) and bland diet (choice C) are not appropriate for this type of surgery as they may not provide the necessary post-operative care and support needed for healing.

3. 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.

4. A client reports hearing voices. What should the nurse do next?

• A. Touch the client to help him return to reality.
• B. Leave the client alone until reality returns.
• C. Ask the client to describe what is happening.
• D. Tell the client there are no voices.

Correct answer: C

Rationale: When a client reports hearing voices, it might indicate hallucinations. It is essential for the nurse to ask the client to describe what is happening to gain a better understanding of the hallucinations. This approach helps in assessing the severity and content of the hallucinations, which can guide further interventions. Touching the client without consent can be intrusive and may escalate the situation, violating the client's personal space. Leaving the client alone may not address the underlying issue of hallucinations and can lead to potential risks if the client is distressed. Telling the client there are no voices denies their experience, invalidates their feelings, and can result in mistrust between the client and the nurse.

5. A 25-year-old male is brought to the emergency room with a piece of metal in his eye. Which action by the nurse is correct?

• A. Use a magnet to remove the object.
• B. Rinse the eye thoroughly with saline.
• C. Cover both eyes with paper cups.
• D. Administer eye drops immediately.

Correct answer: C

Rationale: Covering both eyes with paper cups is the correct action as it helps prevent consensual movement of the affected eye. Attempting to remove the object with a magnet might cause trauma, making choice A incorrect. While rinsing the eye with saline may be necessary, it should be ordered by a doctor and is not the initial action for the nurse, making choice B incorrect. Administering eye drops immediately, as in choice D, is not appropriate in this scenario and does not address the primary concern of preventing further damage by limiting eye movement.
