A nurse is caring for a 70-year-old male client on a medical-surgical unit.
Which action should the nurse take next?
Administer a blood transfusion.
Monitor the client for signs of infection.
Reassess the insertion site for bleeding.
Notify the provider of the client's vital signs.
The Correct Answer is A
Choice A rationale: An oxygen saturation of 84% indicates severe hypoxemia. Normal oxygen saturation levels are between 95% and 100%. A level this low can impair tissue oxygenation and lead to life-threatening complications like respiratory failure or cardiac arrest.
Choice B rationale: An elevated blood pressure of 168/90 mm Hg, while concerning, does not immediately signify a life-threatening condition. It can be a result of distress or pain and needs management but is not as critical as severe hypoxemia.
Choice C rationale: A respiratory rate of 27/min is elevated but not immediately life-threatening. It indicates the body's effort to compensate for hypoxemia, but the underlying issue of low oxygen saturation is more critical to address.
Choice D rationale: A heart rate of 98/min, although increased, does not indicate a life-threatening condition. The elevation may be due to distress or medication side effects. Managing hypoxemia is more urgent to prevent further complications.

Correct Answer is C
Explanation
Choice A rationale
A carotid bruit is indicative of arterial turbulence, often associated with atherosclerosis or vascular narrowing. This finding does not correlate with the assessment of ineffective cardiac contractions.
Choice B rationale
Heart murmurs result from abnormal valve function or turbulent intracardiac blood flow and are unrelated to the assessment of contraction efficacy in this scenario.
Choice C rationale
Pulse deficit reflects ineffective cardiac contractions where some heartbeats fail to produce adequate stroke volume to generate palpable pulses, highlighting impaired cardiac output and perfusion.
Choice D rationale
A bounding radial pulse demonstrates robust ventricular contractions, often due to sympathetic activation or increased blood volume, and does not signify poor cardiac contraction effectiveness.
Correct Answer is B
Explanation
Choice A rationale: Hypoglycemia typically presents with symptoms such as sweating, shakiness, confusion, and palpitations. The client's severe abdominal pain, nausea, vomiting, and jaundice are not consistent with hypoglycemia.
Choice B rationale: Pancreatitis is characterized by severe abdominal pain, nausea, vomiting, fever, and jaundice. The client's symptoms, including severe abdominal pain, nausea, vomiting, and faint yellow hue to sclera, are consistent with pancreatitis2.
Choice C rationale: Myocardial infarction usually presents with chest pain, shortness of breath, sweating, and nausea. The client's primary symptom is severe abdominal pain, which is not typical for myocardial infarction4.
Choice D rationale: Gastroenteritis typically presents with symptoms such as diarrhea, nausea, vomiting, and abdominal cramps. The client's severe abdominal pain, jaundice, and fever are more indicative of pancreatitis than gastroenteritis6.
