A nurse is contributing to the plan of care for a client during a sickle cell crisis. Which of the following interventions should the nurse recommend?

Ambulate the client every 1 hr.

Apply cold compresses to painful joints.

Withhold opioids until the crisis is resolved.

Administer oxygen via nasal cannula.

Answer and Explanation

The Correct Answer is D

Choice A reason: This is an incorrect intervention, because ambulating the client every 1 hr can increase the oxygen demand and worsen the sickling of the red blood cells.

Choice B reason: This is an incorrect intervention, because applying cold compresses to painful joints can cause vasoconstriction and reduce the blood flow to the affected areas.

Choice C reason: This is an incorrect intervention, because withholding opioids until the crisis is resolved can cause unnecessary suffering and increase the stress response, which can trigger more sickling.

Choice D reason: This is the correct intervention, because administering oxygen via nasal cannula can improve the oxygen saturation and prevent further sickling of the red blood cells.

Correct Answer is D

Explanation

Choice A reason: Having the client gently blow clots from his nose every 5 min is an incorrect action, because it can increase the bleeding and trauma to the nasal mucosa. The client should avoid blowing or picking his nose.

Choice B reason: Instructing the client to sit with his head hyperextended is an incorrect action, because it can cause the blood to drain into the throat and increase the risk of aspiration or vomiting. The client should sit with his head tilted forward.

Choice C reason: Applying ice compresses to the back of the client’s neck is an incorrect action, because it has no effect on the bleeding site. The nurse should apply ice compresses to the bridge of the nose or the cheeks to constrict the blood vessels and reduce the bleeding.

Choice D reason: Pinching the soft portion of the client’s nose for 10 min is a correct action, because it applies direct pressure to the bleeding site and allows clot formation. The nurse should instruct the client to breathe through his mouth and avoid swallowing the blood.

A. Respiratory alkalosis B. Metabolic acidosis C. Respiratory acidosis D. Metabolic alkalosis

Correct Answer is A

Explanation

Choice A reason: This is the correct imbalance, because respiratory alkalosis is a condition that occurs when the blood pH is high, the PaCO2 is low, and the HCO3 is normal or low. Respiratory alkalosis is caused by hyperventilation, which can result from anxiety, fever, pain, or mechanical ventilation.

Choice B reason: This is an incorrect imbalance, because metabolic acidosis is a condition that occurs when the blood pH is low, the PaCO2 is normal or low, and the HCO3 is low. Metabolic acidosis is caused by the accumulation of acids in the blood, which can result from diabetic ketoacidosis, renal failure, or lactic acidosis.

Choice C reason: This is an incorrect imbalance, because respiratory acidosis is a condition that occurs when the blood pH is low, the PaCO2 is high, and the HCO3 is normal or high. Respiratory acidosis is caused by hypoventilation, which can result from airway obstruction, chest injury, or narcotic overdose.

Choice D reason: This is an incorrect imbalance, because metabolic alkalosis is a condition that occurs when the blood pH is high, the PaCO2 is normal or high, and the HCO3 is high. Metabolic alkalosis is caused by the loss of acids from the blood, which can result from vomiting, gastric suction, or diuretic therapy.
