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. During a well-baby check of a 6-month-old infant, the nurse notes abrasions and petechiae of the palate. The nurse should:

• A. inquire about the possibility of sexual abuse.
• B. ask about the types of foods the child is eating.
• C. request to see the type of bottle used for feedings.
• D. question the parent about objects the child plays with.

Correct answer: A

Rationale: The correct answer is to inquire about the possibility of sexual abuse. Injuries to the soft palate such as bruising, abrasions, and petechiae can be signs of sexual abuse in infants. While oral sex may not leave significant physical evidence, these findings should raise suspicion. Option A is correct as it focuses on addressing potential abuse. Options B, C, and D are incorrect because the child's diet, the type of bottle used for feedings, and play objects are not likely related to the observed injuries. The presence of oral injuries suggests considering sexual abuse rather than other factors.

3. The client is receiving heparin for thrombophlebitis of the left lower extremity. Which of the following drugs reverses the effects of heparin?

• A. Cyanocobalamin
• B. Protamine sulfate
• C. Streptokinase
• D. Sodium warfarin

Correct answer: B

Rationale: The correct answer is Protamine sulfate. Protamine sulfate is the antidote for heparin, as it reverses its effects. Cyanocobalamin is a form of Vitamin B12 and is not used to reverse heparin effects. Streptokinase is a thrombolytic agent that is used to dissolve blood clots, not to reverse heparin effects. Sodium warfarin is an anticoagulant, but it is not the antidote for heparin. Therefore, answers A, C, and D are incorrect as they do not reverse the effects of heparin.

4. A client with cancer is to undergo an intravenous pyelogram. The nurse should:

• A. Ensure adequate fluid intake 24 hours before the procedure
• B. Ask the client to void immediately before the study
• C. Administer medication that affects the central nervous system as prescribed
• D. Position the client appropriately for the procedure

Correct answer: B

Rationale: The correct answer is to ask the client to void immediately before the study. For an intravenous pyelogram, the client may have orders for laxatives or enemas, so ensuring the client voids before the test is important to prevent obscuring visualization of the kidney, ureters, and bladder. Choice A is incorrect because there is no need to force fluids before the procedure. Choice C is incorrect as medications affecting the central nervous system should not be held unless specified by the healthcare provider. Choice D is incorrect as covering the reproductive organs with an x-ray shield is not necessary for an intravenous pyelogram.

5. A 6-year-old with cerebral palsy functions at the level of an 18-month-old. Which finding would support that assessment?

• A. She dresses herself
• B. She pulls a toy behind her
• C. She can build a tower of eight blocks
• D. She can copy a horizontal or vertical line

Correct answer: B

Rationale: The correct answer is 'She pulls a toy behind her.' This behavior is consistent with the developmental stage of an 18-month-old who enjoys push-pull toys. Dressing oneself usually begins around 3 years old, building a tower of eight blocks at approximately 3 years old, and copying a horizontal or vertical line at about 4 years old. Choices A, C, and D are incorrect as they represent skills that are typically observed in older children.
