A patient admitted with acute renal failure asks for pain medication for a headache described as five out of ten on the pain scale. The nurse checks the MAR and sees that the only pain medication ordered is Ibuprofen. Which of the following actions should the nurse take first to ensure patient safety?

Choice A reason: Type 2 diabetes mellitus, while a serious chronic condition, does not directly predispose patients to delirium. Diabetes primarily impacts the body's ability to regulate blood glucose levels, leading to complications such as cardiovascular disease, neuropathy, and nephropathy. However, it is not directly linked to the acute cognitive disturbances seen in delirium unless it leads to severe metabolic derangements, which is less common.

Choice B reason: Alcohol abuse is a significant risk factor for the development of delirium, especially in ICU patients. Chronic alcohol use can lead to a condition known as delirium tremens (DTs) during withdrawal, characterized by severe agitation, confusion, hallucinations, and autonomic hyperactivity. Patients with a history of alcohol abuse may have altered brain chemistry and neurotransmitter imbalances that predispose them to delirium when stressed by illness or surgery. Moreover, alcohol abuse can lead to liver dysfunction, nutritional deficiencies (particularly thiamine), and other systemic issues that further exacerbate the risk.

Choice C reason: Anxiety can exacerbate stress and discomfort in a patient but is not a primary causative factor for delirium. Anxiety may contribute to an increased sense of fear or confusion, especially in an ICU setting. However, it does not cause the profound disruption in cognitive function, attention, and awareness that characterizes delirium.

Choice D reason: Impaired communication might be a consequence or symptom seen in patients with delirium, but it is not a root cause. Patients with pre-existing communication difficulties might struggle more to express symptoms or needs, which could complicate care, but it does not inherently lead to the onset of delirium. Effective communication strategies and aids can help manage these challenges but do not address the underlying neurological changes seen in delirium.

Choice A reason: A blood pressure of 128/76 mm Hg is within the target range for a patient with hypertension, indicating that the current therapy is effectively managing the condition. This reading is below the generally accepted threshold for hypertension, which is 140/90 mm Hg.

Choice B reason: A blood pressure of 148/78 mm Hg is above the target range for hypertension management. This reading suggests that the patient may need an adjustment in their therapy to better control their blood pressure and reduce the risk of cardiovascular complications.

Choice C reason: A blood pressure of 98/56 mm Hg is too low and may indicate hypotension, which can be a concern, especially if the patient experiences symptoms like dizziness or fainting. This reading suggests that the patient's therapy may need to be adjusted to avoid excessively lowering blood pressure.

Choice D reason: A blood pressure of 128/92 mm Hg shows an elevated diastolic pressure, which is above the target range. This indicates that the patient's hypertension is not fully controlled, and adjustments in therapy may be needed to bring both systolic and diastolic pressures within the desired range.
