You are caring for a client in the ED with B/P 254/139 mm Hg. Which of the following actions would you take first?

Elevate the head of the client’s bed

Contact the Rapid Response Team

Tell the client to report vision changes

Insert a peripheral IV

Initiate seizure precautions

Answer and Explanation

The Correct Answer is B

Choice A reason:

Elevating the head of the client’s bed can help reduce blood pressure slightly by promoting venous return and decreasing intracranial pressure. However, this action alone is not sufficient to address the severe hypertension (254/139 mm Hg) the client is experiencing. Immediate medical intervention is required to prevent complications such as stroke, heart attack, or organ damage.

Choice B reason:

Contacting the Rapid Response Team is the highest priority action. The Rapid Response Team is trained to handle critical situations and can provide immediate interventions to stabilize the client’s condition. Severe hypertension at this level requires urgent medical attention to prevent life-threatening complications. The team can administer medications to lower blood pressure quickly and monitor the client closely.

Choice C reason:

Telling the client to report vision changes is important because vision changes can indicate hypertensive retinopathy or increased intracranial pressure. However, this action is not the immediate priority. The client’s blood pressure needs to be controlled urgently to prevent further complications.

Choice D reason:

Inserting a peripheral IV is necessary for administering medications and fluids. While this is an important step, it should follow the immediate action of contacting the Rapid Response Team. The team can then use the IV access to administer antihypertensive medications promptly.

Choice E reason:

Initiating seizure precautions is important because severe hypertension can lead to seizures. However, this action is not the first priority. The primary focus should be on stabilizing the client’s blood pressure through immediate medical intervention.

Correct Answer is B

Explanation

Choice A: Tachycardia

Tachycardia, defined as a heart rate exceeding 100 beats per minute, can affect the accuracy of pulse oximetry readings. When the heart beats too quickly, it may not fill with enough blood between beats, leading to reduced perfusion and oxygen delivery to tissues. However, while tachycardia can influence the readings, it is not the most significant factor compared to hypotension.

Choice B: Hypotension

Hypotension, or low blood pressure, significantly impacts pulse oximetry accuracy. When blood pressure is low, there is reduced perfusion to peripheral tissues, including the extremities where pulse oximeters are typically placed. This reduced perfusion can lead to inaccurate readings, as the device may not detect sufficient blood flow to measure oxygen saturation accurately. Hypotension is a critical factor that can alter pulse oximetry values, making it the most relevant choice.

Choice C: Tachypnea

Tachypnea, or rapid breathing, can affect oxygen levels in the blood but does not directly interfere with the pulse oximeter’s ability to measure oxygen saturation. While it indicates respiratory distress and can lead to hypoxemia, the pulse oximeter can still provide accurate readings unless accompanied by other factors like low perfusion.

Choice D: Fever

Fever can cause peripheral vasodilation, which might theoretically affect pulse oximetry readings by altering blood flow to the extremities. However, this effect is generally minimal compared to the impact of hypotension. Fever alone is unlikely to cause significant inaccuracies in pulse oximetry measurements.

A. He is NPO until the speech-language pathologist performs a swallowing evaluation. B. Be sure to sit him up when you are feeding him to make him feel more natural. C. You may give him a full-liquid diet, but please avoid solid foods until he gets stronger. D. Just be sure to add some thickener in his liquids to prevent choking and aspiration.

Correct Answer is A

Explanation

Choice A: He is NPO until the speech-language pathologist performs a swallowing evaluation.

This is the most appropriate response. NPO stands for “nil per os,” which means nothing by mouth. After a stroke, it is crucial to assess the patient’s ability to swallow safely to prevent aspiration, which can lead to pneumonia and other complications. A speech-language pathologist is trained to evaluate swallowing function and determine the safest diet for the patient. Until this evaluation is completed, the patient should not consume any food or liquids.

Choice B: Be sure to sit him up when you are feeding him to make him feel more natural.

While sitting the patient up during feeding is important to reduce the risk of aspiration, it is not sufficient on its own. Without a proper swallowing evaluation, feeding the patient could still pose significant risks. Therefore, this choice is not the most appropriate response.

Choice C: You may give him a full-liquid diet, but please avoid solid foods until he gets stronger.

A full-liquid diet might seem like a safer option, but without a swallowing evaluation, there is still a risk of aspiration. The patient’s ability to handle even liquids needs to be assessed by a professional before any oral intake is allowed.

Choice D: Just be sure to add some thickener in his liquids to prevent choking and aspiration.

Thickening liquids can help manage dysphagia, but this should only be done after a swallowing evaluation has determined the appropriate consistency. Administering thickened liquids without an evaluation could still result in aspiration if the patient has severe swallowing difficulties.
