Nursing Elites

1. The client is receiving total parenteral nutrition (TPN). Which laboratory value should the LPN/LVN monitor closely to assess for complications?

• A. Serum potassium
• B. Blood glucose
• C. Serum sodium
• D. Serum calcium

Correct answer: B

Rationale: The correct answer is B: Blood glucose. When caring for a client receiving total parenteral nutrition (TPN), monitoring blood glucose levels is essential due to the risk of hyperglycemia. TPN solutions are high in glucose, and clients may be at risk of developing hyperglycemia if the infusion rate is too high or if there are underlying issues such as insulin resistance. Monitoring serum potassium (choice A) is important but not the most crucial value to monitor in clients receiving TPN. Serum sodium (choice C) and serum calcium (choice D) are not directly impacted by TPN administration and are less likely to be affected compared to blood glucose levels.

2. The client is being discharged and has been prescribed furosemide (Lasix). Which statement by the client indicates an understanding of the medication?

• A. I will take this medication on an empty stomach for optimal absorption.
• B. I will weigh myself daily and report any significant weight loss.
• C. I will include potassium-rich foods in my diet while taking this medication.
• D. I will take this medication in the morning to prevent nocturia.

Correct answer: B

Rationale: The correct answer is B. Weighing daily and reporting significant weight loss is crucial when taking furosemide to monitor for potential fluid and electrolyte imbalances. Choice A is incorrect because furosemide is typically taken on an empty stomach for optimal absorption. Choice C is incorrect as furosemide can lead to potassium loss, so potassium-rich foods should be consumed. Choice D is incorrect because furosemide is usually taken earlier in the day to prevent nocturia, not at bedtime.

3. The nurse is caring for a 17-month-old child with acetaminophen poisoning. Which laboratory reports should the nurse review first?

• A. Prothrombin time (PT) and partial thromboplastin time (PTT)
• B. Red blood cell and white blood cell counts
• C. Blood urea nitrogen and creatinine levels
• D. Liver enzymes (AST and ALT)

Correct answer: D

Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the drug's metabolism in the liver. Monitoring liver enzymes such as AST and ALT is crucial as they indicate liver function and damage. Prothrombin time (PT) and partial thromboplastin time (PTT) (Choice A) are coagulation studies and are not the priority in acetaminophen poisoning. Red blood cell and white blood cell counts (Choice B) are not directly related to acetaminophen poisoning. Blood urea nitrogen and creatinine levels (Choice C) assess kidney function, but liver enzymes are more specific for evaluating liver damage in acetaminophen poisoning.

4. In planning care for a premature infant with respiratory distress syndrome, nursing actions are based on the fact that the most likely cause of this problem stems from the infant's inability to

• A. Stabilize alveolar surface tension
• B. Maintain alveolar surface tension
• C. Promote normal pulmonary blood flow
• D. Regulate intra-cardiac pressure

Correct answer: B

Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.

5. While auscultating the anterior chest of a newly admitted patient, what would the nurse expect to hear?

• A. Normal breathing sounds
• B. Wheezing
• C. Crackles
• D. Stridor

Correct answer: A

Rationale: When auscultating the chest, normal breathing sounds are expected in a healthy individual. Wheezing is a high-pitched whistling sound that indicates narrowed airways and is often heard in conditions like asthma. Crackles are fine, crackling sounds heard on inspiration or expiration and are associated with conditions like pneumonia or heart failure. Stridor is a high-pitched, harsh sound heard during inspiration due to upper airway obstruction. Therefore, choices B, C, and D indicate abnormal respiratory findings, while choice A signifies normal breathing sounds.
