Correct Answer is A
Explanation
A. Reflect on how she's feeling, and encourage her to express other fears that she has about his injury – Acknowledging emotions and encouraging open expression helps the mother process her grief and begin adjusting to the reality of the injury.
B. Explain that you aren't sure, but you will ask the physician to talk to her right away – Deferring to the physician misses an opportunity for emotional support.
C. Advise her that it isn’t in his best interest for her to be so upset, and explain the importance of moral support – This dismisses her emotions rather than addressing them.
D. Reassure her that given time and motivation he will return to normal function – Providing false reassurance is inappropriate, as a C5 spinal cord injury results in permanent loss of function.
Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"A"}
Explanation
Answer: The nurse should first address the patient’s oxygen saturation followed by the patient’s hypotension.
Rationale:
1st Priority: Oxygen Saturation → The client’s oxygen saturation has dropped to 88% on room air, which is below the expected range (typically ≥95% in healthy individuals). Hypoxia must be addressed immediately to prevent further complications. The nurse should apply supplemental oxygen and reassess respiratory status.
2nd Priority: Hypotension → The client’s blood pressure has dropped to 94/59 mmHg, which is significantly lower than the earlier reading of 102/76 mmHg. This may contribute to dizziness and syncope. The nurse should monitor for signs of hemodynamic instability, assess for ongoing blood loss (related to heavy menstrual bleeding), and anticipate interventions such as IV fluids or further evaluation for anemia-related hypotension.
