ATI Nursing 100 Day Exam 4 Fundamentals Questions
Extract:
Question 1 of 5
The nurse is performing a dressing change for a patient and notices white skin around the wound edges. The nurse is aware that:
Correct Answer: B
Rationale: White skin around wound edges suggests nonviable tissue (maceration or necrosis) requiring surgical debridement to remove dead tissue and promote healing. Excessive moisture may contribute but is not the primary issue repositioning prevents pressure injuries not white skin and white skin is not a normal healing sign.
Question 2 of 5
The nursing assessment finding that represents the most serious indication of a client's deteriorating oxygenation status is:
Correct Answer: C
Rationale: Cyanosis (bluish skin/mucous membranes) indicates severe oxygenation failure due to inadequate oxygen delivery reflecting critical hypoxia. Pursed-lip breathing is compensatory clubbing is chronic and skin turgor relates to hydration not oxygenation.
Question 3 of 5
A client is diagnosed with chronic constipation. The nurse is given an order by the physician to administer a glycerin suppository. What abbreviation will be written in the physician's order for the administration route for the suppository?
Correct Answer: D
Rationale: PR (per rectum) is the correct abbreviation for rectal administration of a glycerin suppository as it specifies the route. S/P (status post) indicates past events RS is not a standard abbreviation and R is ambiguous.
Question 4 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 5 of 5
The nurse has applied a topical agent to the client's skin and then applies an ice pack to the area. This is done to:
Correct Answer: B
Rationale: An ice pack slows topical drug absorption by causing vasoconstriction which reduces blood flow to the area allowing prolonged local action of the medication. It is not primarily used for comfort as cooling may not always reduce discomfort. Drug excretion is not affected by topical ice and maximizing distribution would require increased blood flow not reduction.
