A nurse is caring for a client who has hypokalemia. Which of the following findings should the nurse associate with hypokalemia?

Hyperventilation

Bradypnea

Syncope

U waves on electrocardiogram

Answer and Explanation

The Correct Answer is D

A. Hyperventilation: Hyperventilation is more commonly associated with respiratory alkalosis or anxiety rather than hypokalemia. Hypokalemia does not typically cause hyperventilation.

B. Bradypnea: Bradypnea (slow breathing) is not a common finding in hypokalemia. Hypokalemia can affect muscle function, including respiratory muscles, but bradypnea is not a characteristic sign.

C. Syncope: While syncope (fainting) can occur due to various conditions, it is not a specific or common finding directly associated with hypokalemia. Hypokalemia mainly affects the heart and muscles.

D. U waves on electrocardiogram: U waves are a classic electrocardiogram (ECG) finding associated with hypokalemia. These waves appear after the T wave and are indicative of the electrolyte imbalance affecting cardiac repolarization.

Correct Answer is B

Explanation

A. Reposition the client every 4 hr.: Repositioning should be done more frequently, typically every 2 hours, to prevent complications such as pressure ulcers.

B. Place the head of the client's bed at 40° when supine: Elevating the head of the bed to 30-45° helps reduce the risk of ventilator-associated pneumonia (VAP) by preventing aspiration.

C. Turn off the ventilator alarms before suctioning the client's airway: Ventilator alarms should never be turned off as they are critical for monitoring the client's status. Alarms can be temporarily silenced, but only for the duration of the procedure.

D. Provide mouth care every 10 to 12 hr with hydrogen peroxide: Mouth care should be provided more frequently, typically every 4 hours, to reduce the risk of infection. Hydrogen peroxide is not commonly used due to its potential to cause irritation and harm to oral tissues.

A. Repeating the same question over and over B. Awareness of COPD manifestations C. Anxiety and restlessness D. Motivation and engagement of the client

Correct Answer is B

Explanation

A. Repeating the same question over and over: This behavior might indicate confusion or lack of understanding but is not a typical anticipated outcome of education. Effective education should lead to better understanding rather than repeated questions.

B. Awareness of COPD manifestations: An anticipated outcome of education for a client with COPD is increased awareness of their condition and its manifestations. This knowledge helps the client manage their symptoms and recognize exacerbations early.

C. Anxiety and restlessness: While some anxiety might be present, effective education aims to reduce anxiety by providing information and strategies for managing COPD. The goal is to increase confidence and knowledge, which can help mitigate anxiety.

D. Motivation and engagement of the client: While motivation and engagement are positive outcomes, they are not the primary focus of initial educational interventions. The primary goal is to ensure that the client is aware of their condition and understands how to manage it effectively.
