Nursing Elites

1. 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.

2. Due to a high census, it has been necessary for a number of clients to be transferred to other units within the hospital. Which client should be transferred to the postpartum unit?

• A. A 66-year-old female with gastroenteritis
• B. A 40-year-old female with a hysterectomy
• C. A 27-year-old male with severe depression
• D. A 28-year-old male with ulcerative colitis

Correct answer: B

Rationale: The best client to transfer to the postpartum unit is the 40-year-old female with a hysterectomy. The nurses on the postpartum unit will be knowledgeable about postoperative care and can manage any complications related to the surgery. Choices A and D would be more appropriately cared for on a medical-surgical unit due to their conditions. Choice C should be transferred to a psychiatric unit for specialized care related to severe depression.

3. To ensure safety while administering a nitroglycerine patch, what should the nurse do?

• A. Wear gloves
• B. Shave the area where the patch will be applied
• C. Wash the area thoroughly with soap and rinse with hot water
• D. Apply the patch to the buttocks

Correct answer: A

Rationale: To protect herself, the nurse should wear gloves when applying a nitroglycerine patch or cream. Answer B is incorrect because shaving the area where the patch will be applied might abrade the skin, increasing the risk of irritation. Answer C is incorrect because washing with hot water can vasodilate the skin, potentially increasing the absorption of nitroglycerine. Nitroglycerine patches should be applied to areas above the waist, making answer D incorrect as applying it to the buttocks is not recommended.

4. How can medication bound to protein affect drug availability?

• A. enhanced drug availability
• B. rapid distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. increased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.

5. 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.
