1. How should a healthcare professional monitor a patient with a central line for infection?

A. Monitor the dressing site daily
B. Check for redness and swelling
C. Monitor for fever
D. Flush the central line

Correct answer: A

Rationale: Monitoring the dressing site daily is crucial for detecting early signs of infection in patients with central lines. Checking for redness and swelling (choice B) is important but may indicate a more advanced stage of infection. Monitoring for fever (choice C) can also be a sign of infection, but it is a later manifestation. Flushing the central line (choice D) is necessary for maintaining patency but does not directly monitor for infection.

2. What is the best method to manage fluid overload in a patient with heart failure?

A. Administer diuretics
B. Provide oral fluids
C. Increase fluid intake
D. Provide chest physiotherapy

Correct answer: A

Rationale: Administering diuretics is the best method to manage fluid overload in a patient with heart failure. Diuretics help to remove excess fluid from the body by increasing urine output, thus reducing the fluid volume in the bloodstream and tissues. Providing oral fluids (choice B) or increasing fluid intake (choice C) would exacerbate the fluid overload rather than managing it. Chest physiotherapy (choice D) is not indicated for managing fluid overload in heart failure; it is more commonly used for conditions affecting the lungs or airways.

3. A healthcare professional is assessing a client who has chronic kidney disease. Which of the following findings is an indication for hemodialysis?

A. BUN 16 mg/dL
B. Serum magnesium 1.8 mg/dL
C. Serum phosphorus 4.0 mg/dL
D. Glomerular filtration rate of 14 mL/min

Correct answer: D

Rationale: A glomerular filtration rate of 14 mL/min indicates severe kidney impairment and the need for hemodialysis. The other choices, such as BUN 16 mg/dL, serum magnesium 1.8 mg/dL, and serum phosphorus 4.0 mg/dL, are within normal ranges and do not directly indicate the need for hemodialysis in chronic kidney disease.

4. Which lab test is used to assess renal function?

A. Check blood glucose levels
B. Monitor serum creatinine
C. Monitor BUN
D. Check electrolyte levels

Correct answer: B

Rationale: The correct answer is B: Monitor serum creatinine. Serum creatinine is a key indicator of renal function as it reflects the glomerular filtration rate. An increase in serum creatinine levels indicates impaired kidney function. Checking blood glucose levels (choice A) is not specific to assessing renal function but is used to diagnose diabetes. Monitoring BUN (choice C) is important but not as specific as serum creatinine in assessing renal function. Checking electrolyte levels (choice D) is essential in assessing kidney function but is not as specific as monitoring serum creatinine.

5. How should a healthcare professional administer a subcutaneous injection?

A. Insert the needle at a 45-degree angle
B. Insert the needle at a 90-degree angle
C. Use a Z-track method
D. Insert the needle at a 15-degree angle

Correct answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.
