ATI Nursing 100 Day Exam 4 Fundamentals Questions
Extract:
Question 1 of 5
The nurse knows that which form of medication delivery results in the most predictable onset and most bioavailability to the client?
Correct Answer: A
Rationale: Intravenous delivery provides immediate onset and 100% bioavailability by directly entering the bloodstream bypassing barriers like the gastrointestinal tract or skin. Oral routes face first pass metabolism subcutaneous absorption varies with tissue and transdermal has slow onset due to skin diffusion.
Question 2 of 5
It is most critical for the nurse to use a filtered needle when preparing a parenteral medication that:
Correct Answer: A
Rationale: A filtered needle prevents glass particles from an ampule (broken to access medication) entering the syringe reducing risks of tissue damage or embolism. Mixing medications reconstitution or clear solutions do not inherently produce particles requiring filtration.
Question 3 of 5
A client has a serum potassium level of 6.3 mEq/L. The nurse recognizes that the highest priority intervention(s) for this client are to:
Correct Answer: C,E
Rationale: Hyperkalemia (6.3 mEq/L above normal 3.5-5.0 mEq/L) risks cardiac dysrhythmias and neuromuscular issues requiring immediate assessment for muscle weakness/flaccid paralysis and cardiac monitoring to detect life-threatening arrhythmias. Diluting potassium or encouraging potassium-rich foods worsens hyperkalemia and intake/output monitoring is secondary.
Question 4 of 5
A nurse is caring for a client being treated for hypernatremia. Which of the following are appropriate nursing interventions? (Select all that apply)
Correct Answer: B,D,E
Rationale: Restricting sodium reduces hypernatremia by lowering sodium intake monitoring vital signs detects fluid balance changes such as blood pressure or pulse alterations and tracking intake/output assesses fluid status to ensure proper hydration. Encouraging potassium-rich foods is unrelated to sodium levels and decreasing water intake worsens hypernatremia by concentrating sodium further risking dehydration and complications like seizures.
Question 5 of 5
Which one of the following blood levels would provide the nurse with the most information about the ability of the client's blood to transport oxygen? The:
Correct Answer: D
Rationale: Hemoglobin carries oxygen in the blood binding it in red blood cells making its level the best indicator of oxygen transport capacity. Carbon dioxide is exhaled surfactant aids lung compliance and bicarbonate regulates pH none directly affect oxygen transport.
