A nurse is reinforcing teaching with a client who is scheduled for an intravenous pyelogram.

Which of the following statements by the client indicates an understanding of the teaching?

A. Write the information at an 8th-grade reading level: This is a good practice. Writing at an 8th-grade reading level ensures that the brochure is understandable for a wide audience, including those with varying levels of literacy. It helps make the information clear and accessible.

B. Present information from complex to simple: This approach is not ideal. It is generally more effective to present information from simple to complex to build understanding progressively. Starting with basic concepts helps the reader grasp foundational information before moving to more detailed content.

C. Explain medical terminology using basic, one-syllable words: While using simple language is important, basic, one-syllable words might not always be appropriate for explaining medical terminology accurately. It is better to use plain language that conveys the meaning clearly, rather than overly simplifying complex terms.

D. Use a 12-point font size: Using a 12-point font size is generally appropriate and readable for most brochures. However, depending on the audience, a slightly larger font size (e.g., 14-point) may be preferable to enhance readability.

Hyperkalemia refers to an elevated level of potassium in the blood. It can have various manifestations, and one of the critical effects of hyperkalemia is its impact on cardiac function. High levels of potassium can disrupt the normal electrical conduction in the heart, leading to arrhythmias or irregular heart rate. These arrhythmias can range from mild palpitations to more severe and life-threatening conditions like ventricular fibrillation.

Dry mucous membranes are more commonly associated with dehydration or reduced fluid intake. Hyperkalemia does not directly cause dry mucous membranes.

Trousseau's sign is a clinical manifestation of hypocalcemia, not hyperkalemia. It is characterized by carpal spasm induced by inflating a blood pressure cuff above the client's systolic blood pressure for a few minutes.

Hyperactive reflexes are commonly seen in conditions such as hyperthyroidism or certain neurologic disorders. They are not directly related to hyperkalemia.
