Nursing Elites

1. When assessing a client with early impairment of oxygen perfusion, such as a pulmonary embolus, the nurse should expect to find restlessness and which of the following symptoms?

• A. cool, clammy skin
• B. bradycardia
• C. tachycardia
• D. eupnea

Correct answer: C

Rationale: When a client has early impairment of oxygen perfusion, such as in a pulmonary embolus, the nurse should expect to find restlessness, diaphoresis, tachycardia, and cool skin. Tachycardia is a compensatory mechanism to increase oxygen delivery to tissues. Cool, clammy skin (choice A) is more indicative of impaired oxygen perfusion compared to warm, dry skin. Bradycardia (choice B) is less likely to occur in the early stages and is more common in severe cases. Eupnea (choice D) refers to normal respirations in rate and depth, which may not be altered in early impairment of oxygen perfusion.

2. A client had a colostomy done one day ago. Which of the following is an abnormal finding when assessing the stoma?

• A. mild edema
• B. minimal bleeding
• C. rose color
• D. dark red color

Correct answer: D

Rationale: A dark red color is an abnormal finding when assessing the stoma as it indicates inadequate blood supply, possibly due to ischemia. Mild edema, minimal bleeding, and a rose color are expected findings one day post colostomy surgery. Mild edema can be present due to tissue trauma and inflammation, minimal bleeding can occur initially, and a healthy stoma typically appears pink to red, known as a rose color, indicating good blood supply and tissue perfusion. Therefore, the dark red color is the abnormal finding in this scenario.

3. Which of the following is not a primary function of the kidneys?

• A. blood pressure control
• B. vitamin D activation
• C. erythropoietin production
• D. reabsorption of waste products

Correct answer: D

Rationale: The correct answer is reabsorption of waste products because the kidneys excrete waste products rather than reabsorbing them. Choices A, B, and C are indeed primary functions of the kidneys. The kidneys play a crucial role in regulating blood pressure, activating vitamin D, and producing erythropoietin, which stimulates red blood cell production. Therefore, the primary role of the kidneys is to filter blood, remove waste products, regulate fluid balance, and maintain electrolyte balance.

4. The LPN is preparing to ambulate a client post total knee replacement. Which of the following actions should the nurse perform prior to ambulating the client?

• A. Assist the client to a sitting position at the edge of the bed
• B. Have the client march in place for 30 seconds
• C. Have the client raise his arms above his head
• D. Ask the client the last time he fell

Correct answer: A

Rationale: The correct action to perform before ambulating a client post total knee replacement is to assist the client to a sitting position at the edge of the bed. This step is crucial to prevent orthostatic hypotension and ensure the client is ready to stand and walk safely. Having the client march in place or raise his arms above his head are not necessary preparations for ambulation. While knowing about the client's fall history is important for safety reasons, it is not the priority action immediately before ambulating the client.

5. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?

• A. PaO2 90 mm Hg
• B. Bicarbonate 15 mEq/L
• C. CO2 47 mm Hg
• D. pH 7.34

Correct answer: B

Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.
