Nursing Elites

1. The nurse is caring for a patient who has recurrent urinary tract infections. The patient’s current infection is not responding to an antibiotic that has been used successfully several times in the past. The nurse understands that this is most likely due to

• A. acquired bacterial resistance.
• B. cross-resistance.
• C. inherent bacterial resistance.
• D. transferred resistance.

Correct answer: A

Rationale: The correct answer is A: acquired bacterial resistance. Acquired resistance happens when an organism has been exposed to the antibacterial drug, making it less effective over time. Cross-resistance (B) occurs when resistance to one drug leads to resistance to another. Inherent resistance (C) happens without prior exposure to the drug, meaning the bacteria are naturally resistant. Transferred resistance (D) involves the transfer of resistant genes from one organism to another, contributing to resistance development.

2. A client tells the nurse that he has been experiencing frequent heartburn and has been 'living on antacids.' For which acid-base disturbance does the nurse recognize a risk?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: B

Rationale: The correct answer is B: Metabolic alkalosis. In this scenario, the client's frequent use of antacids containing alkaline components can lead to an excess of bicarbonate in the body, causing metabolic alkalosis. Oral antacids work by neutralizing stomach acid, potentially leading to an alkaline shift in the body's pH balance. Choices A, C, and D are incorrect. Metabolic acidosis is not typically associated with antacid use. Respiratory acidosis and respiratory alkalosis are related to respiratory system dysfunction rather than antacid ingestion.

3. In a client with heart failure presenting bilateral +4 edema of the right ankle extending up to midcalf while sitting with legs dependent, what is the priority goal?

• A. Decrease venous congestion.
• B. Maintain normal respirations.
• C. Maintain body temperature.
• D. Prevent injury to lower extremities.

Correct answer: A

Rationale: The priority goal in this scenario is to decrease venous congestion. By elevating the legs above the heart level, venous return is improved, reducing congestion in the lower extremities. This intervention helps decrease swelling and prevents complications such as impaired tissue perfusion. Maintaining normal respirations and body temperature are important aspects of care but are secondary to addressing the immediate issue of venous congestion. Preventing injury to lower extremities is also essential but takes precedence after managing the venous congestion to prevent further complications.

4. A client with diabetes mellitus is scheduled to have blood drawn for a fasting blood glucose determination in the morning. What does the nurse tell the client is acceptable to consume on the morning of the test?

• A. Water
• B. Tea without sugar
• C. Coffee without milk
• D. Clear liquids like apple juice

Correct answer: A

Rationale: The correct answer is A: Water. A client scheduled for a fasting blood glucose test should only consume water after midnight to ensure accurate test results. Choosing options B, C, or D, which include tea, coffee, or clear liquids like apple juice, is incorrect as they may contain substances that can affect the blood glucose levels, leading to inaccurate test results.

5. Which of the following lab values would be most concerning in a patient receiving heparin therapy?

• A. Elevated hemoglobin levels.
• B. Low platelet count.
• C. High potassium levels.
• D. Low sodium levels.

Correct answer: B

Rationale: A low platelet count is most concerning in patients receiving heparin therapy due to the risk of heparin-induced thrombocytopenia. Heparin can sometimes cause a drop in platelet count, leading to a potentially serious condition where blood does not clot as it should. This can result in excessive bleeding or clot formation in blood vessels. Elevated hemoglobin levels, high potassium levels, and low sodium levels are not typically associated with heparin therapy and are less likely to cause immediate concerns or complications in this context.
