Nursing Elites

1. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

• A. BP 142/88 mmHg
• B. 2+ edema of fingers and hands
• C. Radial pulse volume is +3
• D. Capillary refill time is 2 seconds

Correct answer: B

Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.

2. The healthcare professional is monitoring a client receiving IV potassium chloride. Which assessment finding should prompt the healthcare professional to immediately stop the infusion?

• A. The client reports pain at the IV site
• B. The client’s heart rate is irregular
• C. The client has swelling at the IV site
• D. The client’s blood pressure is elevated

Correct answer: B

Rationale: An irregular heart rate is a critical sign of hyperkalemia, a serious condition that can lead to life-threatening cardiac arrhythmias. Stopping the infusion promptly is crucial to prevent further complications. The healthcare professional should inform the healthcare provider immediately for further evaluation and management. Choice A is incorrect because pain at the IV site is common and may not necessitate stopping the infusion. Choice C is incorrect as swelling at the IV site may indicate a local reaction but is not a reason to stop the infusion. Choice D is incorrect as an elevated blood pressure alone is not a direct indication to stop the infusion of IV potassium chloride.

3. A CVA (stroke) patient goes into respiratory distress and is placed on a ventilator. The client’s daughter arrives with a durable power of attorney and a living will that indicates there should be no extraordinary life-saving measures. What action should the nurse take?

• A. Refer to the risk manager
• B. Notify the healthcare provider
• C. Discontinue the ventilator
• D. Review the medical record

Correct answer: B

Rationale: In this situation, the nurse should notify the healthcare provider. The healthcare provider needs to be informed to review the legal documents provided by the patient's daughter, such as the durable power of attorney and living will, which specify the patient's wishes regarding life-saving measures. The healthcare provider will be responsible for making the appropriate decision based on the legal documents and the patient's current condition. Referring to the risk manager (choice A) is not necessary as the issue at hand pertains to the patient's medical care. Discontinuing the ventilator (choice C) without healthcare provider input could go against the patient's wishes and legal documents. Reviewing the medical record (choice D) may not provide immediate guidance on the current situation and the patient's preferences regarding life-saving measures.

4. The healthcare professional counts an adult's apical heartbeat at 110 beats per minute. The healthcare professional describes this as:

• A. Asystole
• B. Bigeminy
• C. Tachycardia
• D. Bradycardia

Correct answer: C

Rationale: Tachycardia is a heart rate greater than 100 beats per minute. In this case, an adult's heart rate of 110 beats per minute falls within the range of tachycardia. Tachycardia can be a common physiological response to various stresses on the body, leading to an increased heart rate. Asystole refers to the absence of cardiac activity, bigeminy is a specific heart rhythm pattern, and bradycardia is a heart rate below 60 beats per minute in adults.

5. The nurse is providing discharge teaching to a client with a new diagnosis of osteoporosis. Which instruction should the nurse include?

• A. Increase dietary intake of calcium-rich foods.
• B. Avoid activities that increase the risk of falls.
• C. Avoid prolonged exposure to sunlight.
• D. Increase intake of vitamin D supplements.

Correct answer: B

Rationale: Avoiding activities that increase the risk of falls (B) is the most crucial instruction for a client with osteoporosis to prevent fractures. Osteoporosis weakens bones, making them more susceptible to fractures from falls. While increasing calcium intake (A) is important for bone health, avoiding falls takes precedence to prevent immediate harm. Avoiding prolonged exposure to sunlight (C) is not directly related to osteoporosis management. Increasing vitamin D supplements (D) is beneficial for bone health, but fall prevention is more critical in this scenario.
