Nursing Elites

1. Why might the physician order antibiotics to be given through the central venous access device (CVAD) rather than through a peripheral IV line if the CVAD becomes infected?

• A. To prevent infiltration of the peripheral line
• B. To reduce the pain and discomfort associated with antibiotic administration in a small vein
• C. To lessen the chance of an allergic reaction to the antibiotic
• D. To attempt to eliminate microorganisms in the catheter and prevent having to remove it

Correct answer: D

Rationale: When a patient's central venous access device (CVAD) becomes infected, administering antibiotics through the line is essential to attempt to eliminate microorganisms within the catheter. The goal is to prevent the necessity of removing the catheter, which might be required if the infection persists. Choice A, 'To prevent infiltration of the peripheral line,' is incorrect as the priority is addressing the catheter infection, not preventing issues with a peripheral line. Choice B, 'To reduce the pain and discomfort associated with antibiotic administration in a small vein,' is not relevant to the rationale for choosing the CVAD for antibiotic administration. Choice C, 'To lessen the chance of an allergic reaction to the antibiotic,' is also incorrect as the main focus is managing the catheter-associated infection rather than allergy prevention.

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. While the client is receiving total parenteral nutrition (TPN), which lab test should be evaluated?

• A. Hemoglobin
• B. Creatinine
• C. Blood glucose
• D. White blood cell count

Correct answer: C

Rationale: When a client is receiving total parenteral nutrition (TPN), monitoring blood glucose levels is crucial as TPN solutions contain high amounts of glucose. This monitoring helps prevent hyperglycemia or hypoglycemia. Evaluating hemoglobin (choice A) is not directly related to TPN administration. Creatinine (choice B) is more relevant for assessing kidney function. White blood cell count (choice D) is important for evaluating immune function and infection, but not specifically tied to TPN administration.

4. The new mother asks why her baby has lost weight since he was born. The best explanation of the weight loss is:

• A. The baby is dehydrated due to polyuria.
• B. The baby is hypoglycemic due to lack of glucose.
• C. The baby is allergic to the formula the mother is giving him.
• D. The baby can lose up to 10% of weight due to meconium stool, loss of extracellular fluid, and initiation of breastfeeding.

Correct answer: D

Rationale: After birth, newborns can lose weight due to meconium stool, loss of extracellular fluid, and the initiation of breastfeeding. This weight loss is a normal and expected physiological process, and infants can lose up to 10% of their birth weight during this period. There is no indication of dehydration (polyuria), hypoglycemia (lack of glucose), or allergy to the formula as reasons for weight loss in newborns. Therefore, answers A, B, and C are incorrect. Answer D provides the most accurate explanation for the observed weight loss in the newborn.

5. The nurse is caring for a dying client who has persistently requested that the nurse 'help her to die and be in peace.' According to the Code of Ethics for Nurses, the nurse should:

• A. Ask the client if she has signed an advance directives document.
• B. Tell the client that another nurse will be assigned to care for her.
• C. Instruct the client that only a physician can legally assist in suicide.
• D. Try to make the client as comfortable as possible, but refuse to assist in death.

Correct answer: D

Rationale: According to the Code of Ethics for Nurses, the nurse should try to make the client as comfortable as possible but refuse to assist in death. It is not within the scope of nursing practice to assist in death, even if requested by the client. Choice A is incorrect as advance directives do not directly relate to the client's request for assistance in dying. Choice B is inappropriate as passing the responsibility to another nurse does not address the ethical dilemma at hand. Choice C is incorrect because instructing the client that only a physician can legally assist in suicide does not address the ethical considerations involved in the request. Therefore, the most appropriate action for the nurse is to provide comfort measures while upholding ethical standards and not participating in ending the client's life.
