Nursing Elites

1. A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?

• A. Decreased cardiac output can cause hypoxia to the brain
• B. Mental status changes may be a side effect of the patient's medication
• C. Mitral regurgitation is a complication associated with some neurological disorders
• D. The patient may be confused about his diagnosis

Correct answer: A

Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.

2. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

3. Which finding indicates to the nurse that a patient's transjugular intrahepatic portosystemic shunt (TIPS) placed 3 months ago has been effective?

• A. Increased serum albumin level
• B. Decreased indirect bilirubin level
• C. Improved alertness and orientation
• D. Fewer episodes of bleeding varices

Correct answer: D

Rationale: The correct answer is 'Fewer episodes of bleeding varices.' A transjugular intrahepatic portosystemic shunt (TIPS) is used to reduce pressure in the portal venous system, thus decreasing the risk of bleeding from esophageal varices. This outcome would indicate the effectiveness of the TIPS procedure. The other choices are incorrect because: Increased serum albumin level and decreased indirect bilirubin level are not direct indicators of TIPS effectiveness. Improved alertness and orientation could be influenced by various factors and may not directly correlate with the effectiveness of the TIPS procedure. Additionally, TIPS can actually increase the risk of hepatic encephalopathy, which contradicts the choice of improved alertness and orientation.

4. A client had a closed reduction of a fractured right wrist followed by the application of a fiberglass cast 12 hours ago. Which finding requires immediate attention?

• A. Capillary refill of fingers on right hand is 3 seconds
• B. Skin warm to touch and normally colored
• C. Client reports prickling sensation in the right hand
• D. Slight swelling of fingers of right hand

Correct answer: C

Rationale: A prickling sensation in the right hand is indicative of compartment syndrome, a serious condition that can lead to tissue damage and impaired circulation. Immediate attention is required to prevent complications. Capillary refill of 3 seconds, warm and normally colored skin, and slight swelling of fingers are expected findings after a closed reduction and casting. These findings do not typically indicate a critical issue and can be managed with routine monitoring.

5. Based on Mr. C's assessment, which of the following nursing interventions is most appropriate?

• A. Elevate the lower extremities to 45 degrees to promote venous return
• B. Place Mr. C in the Trendelenburg position
• C. Administer total parenteral nutrition
• D. Monitor urine output

Correct answer: D

Rationale: In the context of Mr. C's assessment, the most appropriate nursing intervention is to monitor urine output. A client in hypovolemic shock may experience decreased urine output due to poor kidney perfusion. By monitoring urine output, the nurse can assess renal function and fluid status. Administering total parenteral nutrition (Choice C) is not indicated based on the information provided, as the priority is to stabilize the client's condition. Elevating the lower extremities (Choice A) may be helpful in some cases but is not the priority in this situation. Placing Mr. C in the Trendelenburg position (Choice B) is contraindicated in hypovolemic shock as it can worsen venous return and compromise cardiac output.
