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 D

Explanation

A. Provide mouth care: Mouth care is important for overall comfort and hygiene but is not the first step in preparing for chest percussion, vibration, and postural drainage. The priority is to prepare the client for the procedures that will aid in clearing lung secretions.

B. Cup hands and tap on the client's chest repeatedly: This action is part of chest percussion and should be performed after positioning the client correctly. Percussion should be done on the appropriate lung areas based on the positioning.

C. Auscultate lung fields: Auscultation of lung fields is essential for assessing lung sounds and determining the effectiveness of therapy. However, it should be done after positioning the client to ensure that the correct areas are being treated and assessed.

D. Position the client so that the lung area to be drained is above the client's trachea: Proper positioning is crucial for effective postural drainage, as it allows gravity to assist in moving secretions from the lung areas to the central airways. This should be done before performing chest percussion or vibration.

A. Nasal saline irrigation alone B. Oral decongestants alone C. Oral antibiotics D. Intranasal corticosteroids alone

Correct Answer is C

Explanation

In cases of acute bacterial sinusitis that last longer than 10 days, worsen after initial improvement, or present with severe symptoms (such as fever and significant facial pain), oral antibiotics are generally indicated. First-line options typically include amoxicillin-clavulanate.

Other options listed, such as nasal saline irrigation, oral decongestants, or intranasal corticosteroids, may help alleviate symptoms but would not address the bacterial infection, making antibiotics the most appropriate primary treatment in this case.
