Nursing Elites

1. A complication of total parenteral nutrition (TPN) is the development of cholestasis. What is this condition?

• A. an inflammatory process of the extrahepatic bile ducts
• B. an arrest of the normal flow of bile
• C. an inflammation of the gallbladder
• D. the formation of gallstones

Correct answer: B

Rationale: Cholestasis due to TPN administration is an intrahepatic process that interrupts the normal flow of bile. It is characterized by a reduction or stoppage of bile flow. Choice A, an inflammatory process of the extrahepatic bile ducts, refers to cholangitis, not cholestasis. Choice C, an inflammation of the gallbladder, describes cholecystitis, a different condition. Choice D, the formation of gallstones, is not correct as cholestasis is about the flow of bile, not the formation of gallstones.

2. A 5-year-old is admitted to the unit following a tonsillectomy. Which of the following would indicate a complication of the surgery?

• A. Decreased appetite
• B. A low-grade fever
• C. Chest congestion
• D. Constant swallowing

Correct answer: D

Rationale: A complication of a tonsillectomy is bleeding, and constant swallowing may indicate bleeding. Decreased appetite is expected after a tonsillectomy, as is a low-grade fever; thus, answers A and B are incorrect. Chest congestion, as mentioned in answer C, is not typical of tonsillectomy complications, making it an incorrect choice.

3. The nurse is caring for a client scheduled for removal of a pituitary tumor using the transsphenoidal approach. The nurse should be particularly alert for:

• A. Nasal congestion
• B. Abdominal tenderness
• C. Muscle tetany
• D. Oliguria

Correct answer: A

Rationale: During the removal of a pituitary tumor using the transsphenoidal approach, nasal congestion is a significant concern as it can further obstruct the airway. This can be due to mucosal swelling, bleeding, or edema resulting from the surgery. Nasal congestion requires immediate attention to prevent airway compromise. Abdominal tenderness, muscle tetany, and oliguria are not directly associated with the pituitary gland or the transsphenoidal approach, making them incorrect choices. Abdominal tenderness is more common in abdominal or pelvic surgeries due to intra-abdominal issues. Muscle tetany is related to electrolyte imbalances or neuromuscular disorders, not specific to pituitary surgery. Oliguria is a concern in renal-related conditions, not typically in pituitary tumor surgeries.

4. A nurse provides information about feeding to the mother of a 6-month-old infant. Which statement by the mother indicates an understanding of the information?

• A. Meats are really important for iron, and I should start feeding meats to my infant right away.
• B. Egg white should not be given to my infant because of the risk for an allergy.
• C. I can mix the food in my infant's bottle if he won't eat it.
• D. Fluoride supplementation is not necessary until permanent teeth come in.

Correct answer: B

Rationale: The correct answer is B: 'Egg white should not be given to my infant because of the risk for an allergy.' Egg white, even in small quantities, is not recommended for infants until the end of the first year of life due to its common allergenic potential. Choice A is incorrect because while meats are important for iron, they are not typically introduced to infants until around 6-8 months. Choice C is incorrect because food should never be mixed with formula in the bottle as it may lead to feeding difficulties and inaccurate monitoring of intake. Choice D is incorrect because fluoride supplementation may be required around 6 months depending on the infant's fluoride intake from water. Introducing solid foods like rice cereal, fruits, or vegetables is usually done around 5-6 months, following healthcare provider recommendations.

5. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.
