ATI Nursing 100 Day Exam 4 Fundamentals Questions
Extract:
Question 1 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 2 of 5
The nurse understands that the major factor affecting oxygenation in a client who has fluid in the lungs is:
Correct Answer: B
Rationale: Fluid in the lungs (e.g. pulmonary edema) impairs oxygen diffusion across the alveolar membrane reducing oxygenation as fluid blocks gas exchange. Poor perfusion lowered hemoglobin or reduced ambient oxygen are secondary or unrelated to lung fluid’s direct effect on diffusion.
Question 3 of 5
The nurse is caring for a client who is at high risk for development of pressure injury. The client is able to move independently but has been placed on bedrest. The client has experienced two episodes of urinary incontinence. Which intervention(s) should the nurse include in the care plan?
Correct Answer: A,D,E
Rationale: Shifting weight every 15 minutes reduces pressure on bony prominences moisture barrier cream protects against incontinence-related skin breakdown and a specialty mattress distributes pressure to prevent ulcers. Raising the bed at 45 degrees increases shear and massaging prominences risks tissue damage.
Question 4 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 5 of 5
The nurse recognizes that the most appropriate reason to suction a client is that:
Correct Answer: D
Rationale: Suctioning is indicated when the client cannot clear secretions effectively as evidenced by gurgling respirations and inability to cough ensuring airway patency. Routine suctioning every eight hours or hourly without clinical need is inappropriate as it may cause trauma or discomfort. Coughing and swallowing sputum indicates effective airway clearance not requiring suctioning.
