A diabetic patient who has had vomiting and diarrhea for the past 3 days is admitted to the hospital with a blood glucose of 748 mg/ml (41.5 mmol/L) and a urinary output of 120 ml in the first hour.
The vital signs are blood pressure (BP) 72/62; pulse 128, irregular and thready; respirations 38; and temperature 97° F (36.1° C). The patient is disoriented and lethargic with cold, clammy skin and cyanosis in the hands and feet.

The nurse recognizes that the patient is experiencing the:

Choice A rationale

While reducing environmental stimuli like light and noise can help decrease agitation in some patients, it does not address the potentially life-threatening physiological causes of restlessness. Restlessness in a mechanically ventilated patient is a primary clinical indicator of hypoxemia or hypercapnia. Failing to assess the patient's oxygenation status first could lead to a delay in recognizing respiratory failure or ventilator malfunction, which could result in permanent organ damage or cardiac arrest.

Choice B rationale

Documentation is a vital part of nursing care, but it must follow a thorough assessment and appropriate intervention. Restlessness is a significant change in clinical status for a ventilated patient and should never be the only action taken. Ignoring the underlying cause of the behavior and simply recording it in the medical record is a failure of nursing judgment that puts the patient at risk for undetected respiratory distress or unplanned self-extubation.

Choice C rationale

Pulse oximetry provides a non-invasive, rapid assessment of the patient's arterial oxygen saturation, with a normal range typically being 95 to 100 percent. Restlessness is often the very first sign of hypoxia as the brain responds to decreased oxygen levels. By checking the saturation immediately, the nurse can determine if the restlessness is due to a physiological need for more oxygen, a dislodged tube, or a need for suctioning before considering psychological or environmental factors.

Choice D rationale

Administering sedation or analgesics to a restless patient without first assessing their respiratory status is dangerous. If the restlessness is caused by hypoxia, adding a sedative will further depress the respiratory drive and mask the clinical signs of distress, leading to a rapid decline in the patient's condition. While comfort is important, the nurse must prioritize the "Airway, Breathing, and Circulation" (ABC) framework and confirm adequate gas exchange before providing any pharmacological chemical restraints.

Choice A rationale

Requesting that family members prepare the body is inappropriate and culturally insensitive in most hospital settings. While some cultures may wish to participate in the washing or dressing of the deceased, the nurse should never assume this or place the burden of postmortem care entirely on grieving relatives. The nurse is responsible for the dignified handling of the body, and the priority is first addressing the emotional needs of the family present.

Choice B rationale

Ensuring the death certificate is completed is a necessary legal and administrative step in postmortem care, but it is not the immediate priority for the nurse at the bedside. The primary focus immediately following the death should be on the psychosocial and emotional support of the family members who are currently experiencing the loss. Administrative tasks can be managed once the family has been initially supported and offered time with their loved one.

Choice C rationale

Calling for emergency assistance to begin resuscitation is inappropriate because the patient is described as terminally ill and has already died. If the patient has a Do Not Resuscitate order or is in the end stages of a terminal disease, performing CPR would be contrary to their wishes and ethically unsound. The nurse's role in this moment is to provide a peaceful environment and support the survivors, rather than initiating futile medical interventions.

Choice D rationale

The priority intervention after a death is to provide compassionate, family-centered care. Offering the family time alone with the deceased allows them to begin the grieving process and say their final goodbyes in a private, respectful environment. This supports the emotional well-being of the survivors and honors the dignity of the patient. Once the family has had this opportunity, the nurse can then proceed with the technical aspects of postmortem body care.
