Nursing Elites

1. A nurse is assessing a client who has asthma. Which of the following areas should the nurse evaluate as the most reliable indicator of central cyanosis?

• A. Oral mucosa
• B. Conjunctivae
• C. Soles of the feet
• D. Ear lobes

Correct answer: A

Rationale: Central cyanosis is best assessed by examining the oral mucosa, as it is a more reliable indicator compared to other areas like the conjunctivae, soles of the feet, and ear lobes. The oral mucosa reflects the oxygen saturation levels of the blood more accurately. Conjunctivae and ear lobes may show cyanosis, but they are not as reliable as the oral mucosa. The soles of the feet are not typically used to assess central cyanosis.

2. A nurse is providing home care for a client who is receiving tube feedings and medication through a gastrostomy tube. The family member providing the feedings reports that the client has begun to have diarrhea. For which of the following practices should the nurse intervene?

• A. Cleanse the bag every 24 hours
• B. Cleanse the bag every 48 hours
• C. Use tap water
• D. Flush the tube every 4 hours

Correct answer: A

Rationale: The correct answer is A. Cleansing the bag every 24 hours can lead to contamination, increasing the risk of infection and diarrhea. Using tap water (choice C) is not recommended for cleaning the gastrostomy tube due to the risk of introducing harmful microorganisms. Cleansing the bag every 48 hours (choice B) is not frequent enough and may also contribute to infection. Flushing the tube every 4 hours (choice D) is a standard practice to ensure patency and should not be intervened by the nurse.

3. A client is prescribed 1g of potassium phosphate IV to be infused continuously over 6 hr. Available is 1 g in 250 ml of dextrose 5%. What rate should the nurse set the IV pump to run at?

• A. 40 ml/hr
• B. 42 ml/hr
• C. 44 ml/hr
• D. 46 ml/hr

Correct answer: B

Rationale: To calculate the IV rate, divide the total volume by the total time in hours. In this case, 1 g in 250 ml is to be infused over 6 hours. Therefore, 250 ml / 6 hr = 42 ml/hr. This means the IV pump should be set to run at 42 ml/hr. Choices A, C, and D are incorrect as they do not accurately calculate the infusion rate based on the provided information.

4. A nurse is planning care for a client who has dehydration and is receiving a continuous IV infusion of 0.9% sodium chloride. Which of the following interventions should the nurse include in the plan of care?

• A. Monitor the client's intake and output every 6 hours
• B. Administer furosemide to the client
• C. Check the client's IV infusion every 8 hours
• D. Offer the client 240 ml (8 oz) of oral fluids every 4 hours

Correct answer: D

Rationale: Offering the client 240 ml (8 oz) of oral fluids every 4 hours is essential to maintain hydration in a client with dehydration who is receiving continuous IV infusion. This intervention helps ensure an adequate fluid balance. Monitoring the client's intake and output every 6 hours is necessary to assess hydration status and response to treatment. Administering furosemide to the client, choice B, is contraindicated in dehydration as it can further deplete fluid volume. Checking the IV infusion every 8 hours, as in choice C, is important but not as critical as ensuring oral fluid intake to promote hydration.

5. A nurse is monitoring an older adult female client who had a myocardial infarction (MI) for the development of an acute kidney injury (AKI). Which of the following findings should the nurse identify as indicating an increased risk of AKI?

• A. Magnesium 2.0 mEq/L
• B. Blood urea nitrogen (BUN) 20 mg/dL
• C. Serum Osmolality 290 mOsm/kg H2O
• D. Serum creatinine 1.8 mg/dL

Correct answer: D

Rationale: An elevated serum creatinine level (1.8 mg/dL) is a significant indicator of potential kidney impairment. In acute kidney injury (AKI), serum creatinine levels rise due to decreased kidney function, reflecting the kidneys' inability to effectively filter waste from the blood. Magnesium level, BUN, and serum osmolality are not direct indicators of kidney function or risk of AKI. Magnesium levels are more related to electrolyte balance, BUN can be affected by factors other than kidney function, and serum osmolality reflects the concentration of solutes in the blood, not specifically kidney function.
