Nursing Elites

1. 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.

2. A nurse is providing teaching to the parent of a child who is receiving oral nystatin for oral candidiasis. Which of the following statements by the parent indicates an understanding of the teaching?

• A. I will mix the medication with applesauce
• B. I will provide a snack with the medication
• C. I will store the medication in the refrigerator
• D. I will swab the inside of my child's mouth with the medication

Correct answer: D

Rationale: The correct answer is D because swabbing the inside of the child's mouth with the nystatin solution is the correct administration method for treating oral candidiasis. Mixing the medication with applesauce or providing a snack with it is not the recommended method of administration. Storing the medication in the refrigerator is also unnecessary and not part of the proper administration instructions.

3. What is the most appropriate method for preventing catheter-associated urinary tract infections (CAUTIs)?

• A. Insert a urinary catheter using clean gloves.
• B. Limit the duration of catheter use.
• C. Use a smaller size catheter to prevent trauma.
• D. Change the catheter tubing every 24 hours.

Correct answer: B

Rationale: The correct answer is B: Limit the duration of catheter use. Limiting the duration of catheterization is a crucial method for preventing catheter-associated urinary tract infections (CAUTIs). Prolonged catheter use increases the risk of introducing pathogens into the urinary tract, leading to infections. Using clean gloves for insertion (choice A) is important for preventing contamination but does not address the main cause of CAUTIs. Using a smaller size catheter (choice C) may help reduce trauma but does not directly prevent infections. Changing the catheter tubing every 24 hours (choice D) is not necessary unless clinically indicated, and it is not the most effective method for preventing CAUTIs.

4. A patient prescribed warfarin is being taught about dietary restrictions by a healthcare provider. Which of the following foods should the patient be instructed to limit?

• A. Bananas
• B. Spinach
• C. Potatoes
• D. Apples

Correct answer: B

Rationale: The correct answer is B: Spinach. Spinach is high in vitamin K, which can interfere with the effectiveness of warfarin, an anticoagulant medication. Patients taking warfarin should limit foods high in vitamin K to maintain the medication's effectiveness and consistent dosage. Bananas, potatoes, and apples are not high in vitamin K and do not typically interfere with warfarin therapy.

5. A healthcare provider is reviewing the laboratory report of a client who is receiving heparin therapy for a deep vein thrombosis. Which of the following lab values indicates a therapeutic response to the therapy?

• A. PT of 12 seconds
• B. aPTT of 70 seconds
• C. Platelets of 150,000/mm3
• D. INR of 1.5

Correct answer: B

Rationale: An aPTT of 70 seconds is within the therapeutic range for a client receiving heparin therapy. The activated partial thromboplastin time (aPTT) is the most sensitive test to monitor heparin therapy. A therapeutic aPTT range for a client receiving heparin is usually 1.5 to 2.5 times the control value. Choices A, C, and D are not indicators of a therapeutic response to heparin therapy. PT measures the extrinsic pathway of coagulation and is not specific to monitoring heparin therapy. Platelet count is important to monitor for heparin-induced thrombocytopenia, but it does not indicate the therapeutic response to heparin therapy. INR is used to monitor warfarin therapy, not heparin therapy.
