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. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

• A. 0.9% sodium chloride
• B. 5% dextrose in water solution
• C. Sterile water
• D. Heparin sodium

Correct answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, Heparin sodium, is an anticoagulant and is not routinely used to flush an IV device before and after the administration of blood.

3. Which of the following clients should refrain from therapy with the thiazide diuretic hydrochlorothiazide?

• A. a client with renal impairment
• B. a client with hypertension
• C. a client with diabetes mellitus, type II
• D. a client with renal calculi (kidney stones)

Correct answer: C

Rationale: The correct answer is a client with diabetes mellitus, type II. Thiazide diuretics like hydrochlorothiazide can cause metabolic abnormalities, including elevated blood glucose levels. This increase is linked to diuretic-induced potassium deficiency, which reduces insulin secretion, leading to higher plasma glucose levels. Thiazides are commonly used in clients with renal impairment and hypertension. Moreover, thiazides decrease calcium excretion, reducing the risk of renal calculi, so it is not contraindicated for clients with kidney stones. Therefore, clients with diabetes mellitus, type II should avoid therapy with hydrochlorothiazide due to the potential adverse effects on blood glucose levels.

4. Which nurse should be assigned to care for the postpartal client with preeclampsia?

• A. The nurse with 2 weeks of experience on the postpartum unit
• B. The nurse with 3 years of experience in labor and delivery
• C. The nurse with 10 years of experience in surgery
• D. The nurse with 1 year of experience in the neonatal intensive care unit

Correct answer: B

Rationale: The nurse with 3 years of experience in labor and delivery (answer B) should be assigned to care for the postpartal client with preeclampsia. This nurse has the most relevant experience and knowledge of possible complications associated with preeclampsia due to their background in labor and delivery. Assigning a nurse with only 2 weeks of experience on the postpartum unit (answer A) would not be suitable for handling the complexities of caring for a client with preeclampsia. Nurses with experience in surgery (answer C) or the neonatal intensive care unit (answer D) lack the specific expertise needed for managing a postpartal client with preeclampsia, making them unsuitable choices for this assignment.

5. During a school screening, a nurse notices small bruises on the anterior and posterior ribs of an 8-year-old Asian child. The nurse should ask the child:

• A. if the family practices coining
• B. who performs coinings
• C. if the child has fallen
• D. how long the child has been abused

Correct answer: A

Rationale: The correct answer is to ask if the family practices coining. In Asian cultures, coining is a traditional practice believed to draw infections from the body. It involves rubbing a heated coin on the chest and torso, which can cause bruising similar to what the nurse noticed on the child's ribs. This question is important to differentiate between cultural practices and potential child abuse. Choices B, C, and D are incorrect because assuming abuse without considering cultural practices can lead to misinterpretation and inappropriate actions. It's crucial for healthcare providers to be culturally sensitive and gather all relevant information before making conclusions.
