Extract:
Question 1 of 5
The nurse is transcribing a medication order and schedules dosing for 10:00 AM 2:00 PM and 6:00 PM. Which medication order is consistent with this schedule?
Correct Answer: B
Rationale: Diazepam three times daily fits the 10:00 AM 2:00 PM and 6:00 PM schedule for three doses within a day. Twice daily (Propranolol) requires wider intervals q4 hours (Cephalexin Morphine) implies every 4 hours not specific times and Morphine is PRN not scheduled.

Question 3 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 4 of 5
On admission to the hospital the nurse notes that the client has a sacral wound that is yellow in color. What wound treatment would the nurse expect the health care provider to order?
Correct Answer: B
Rationale: A yellow wound indicates slough (nonviable tissue) requiring debridement to remove dead tissue and moist dressings to promote healing by maintaining a moist environment conducive to tissue regeneration. Oxygenation does not address slough barrier creams are for prevention and no treatment risks infection and delayed healing.
Question 5 of 5
The nurse understands that the rationale(s) for clients receiving intravenous (IV) therapy is/are to:
Correct Answer: A,D,E
Rationale: IV therapy compensates for fluid/electrolyte losses (e.g. vomiting) corrects imbalances (e.g. hyponatremia) and expands volume in dehydration or hypovolemia. Increasing urine specific gravity indicates concentrated urine not an IV goal and moving fluid to unavailable areas (e.g. cerebrospinal fluid) is not achieved by IV therapy.
