A patient reports that they experience muscle cramping and pain in both legs when walking for short periods.  Which medical term would the nurse document in the patient’s chart?

A 29-year-old patient is admitted after a motor vehicle collision with a suspected cervical spinal cord injury. The patient is immobilized on a spinal board and has decreased movement and sensation in all four extremities. The patient is awake and speaking but has a weak cough. Spinal imaging has been ordered but has not yet been completed, and the cervical spine has not been cleared. Vital signs: BP: 128/76 mmHg HR: 92 beats/min RR: 24 breaths/min SpO₂: 94% on room air Which actions should the nurse take in providing care for this patient? Select all that apply

Four hours later, despite receiving prescribed antibiotics and supplemental oxygen, the nurse notes a change in R.T.’s condition. 1130 Supplemental oxygen increased from 2 L/min nasal cannula to 4 L/min BP: 96/58 mmHg HR: 118 beats/min RR: 34 breaths/min Temp: 102.2°F (39.0°C) SpO₂: 86% on 4L NC Increasingly restless and anxious Bilateral crackles now present Accessory muscle use noted An arterial blood gas is obtained: pH 7.31 (ref: 7.35 – 7.45) PaCO₂ 48 mmHg (ref: 35 – 45 mmHg) PaO₂ 54 mmHg (ref: 80 – 100 mmHg) HCO₃⁻ 23 mEq/L (22 – 26 mEq/L) Question: The nurse analyzes the new findings. Which findings provide evidence that R.T. is developing acute respiratory failure? Select all that apply

A 67-year-old patient hospitalized with severe COVID-19 pneumonia has progressively worsening respiratory status. The patient initially required 4 L/min oxygen via nasal cannula but is now receiving high-flow nasal oxygen at 60 L/min with an FiO₂ of 100%. The nurse notes: SpO₂: 82% RR: 38 breaths/min HR: 126 beats/min BP: 92/54 mmHg Increasing accessory muscle use Increasing fatigue Difficulty maintaining an upright position Increasing confusion Bilateral coarse crackles The following ABG is obtained: pH: 7.28 (ref: 7.35 – 7.45) PaCO₂: 52 mmHg (ref: 35 – 45 mmHg) HCO₃⁻: 24 mEq/L (ref: 22 – 26 mEq/L) PaO₂: 52 mmHg (ref: 80 – 100 mmHg) Question: Which interpretations of the patient’s current condition are supported by the patient’s assessment and clinical data?

A patient with blunt chest trauma has a chest tube inserted for a hemothorax. One hour later, the nurse notes 400 mL of bright-red drainage in the collection chamber. The patient’s blood pressure has decreased from 118/72 to 94/58 mmHg, and heart rate has increased from 92 to 124 beats per min. What is the nurse’s priority action?

The nurse is caring for a 22-year-old patient who presents with a temperature of 103.4°F (39.7°C), severe headache, nuchal rigidity, photophobia, and new confusion. The provider suspects bacterial meningitis. The patient has no documented medication allergies. For each of the following interventions, indicate whether it is appropriate or requires correction in the care of this patient. Nursing Action Clinical Indication Obtain two sets of blood cultures Initiate prescribed droplet isolation precautions Administer prescribed empiric IV broad-spectrum antimicrobial therapy promptly Prepare for lumbar puncture for cerebrospinal fluid (CSF) analysis, unless contraindicated Perform frequent neurologic assessments, per protocol Reduce unnecessary environmental stimulation Encourage frequent visitors to decrease the patient’s anxiety Monitor for manifestations of increasing intracranial pressure (ICP) Wait for CSF culture results before administering antimicrobial therapy

A patient with bacterial pneumonia is receiving noninvasive positive-pressure ventilation. The nurse reviews the following ABG trends: Value 0800 1200 Reference Range PH 7.29 7.25 7.35 – 7.45 PaCO₂ 62 mmHg 72 mmHg 35 – 45 mmHg PaO₂ 68 mmHg 56 mmHg 80 – 100 mmHg FiO₂ 0.40 0.40   Respiratory rate 28 beats/min 34 beats/min   Level of consciousness (LOC) Alert Increasingly difficult to arouse   Which findings indicate that the patient’s respiratory status is worsening?
