A nurse is caring for a client who is taking digoxin. Which of the following findings should the nurse identify as an indication of digoxin toxicity?

Rash

Dyspnea

Polyuria

Bradycardia

Answer and Explanation

The Correct Answer is D

A. Rash: A rash is not a typical manifestation of digoxin toxicity and is more often linked to allergic reactions or dermatologic conditions. While any new rash should be assessed, it does not specifically signal excessive digoxin levels.

B. Dyspnea: Shortness of breath can occur in many cardiac or pulmonary conditions, especially heart failure, but it is not a primary indicator of digoxin toxicity. Dyspnea alone does not reliably reflect rising digoxin concentrations.

C. Polyuria: Increased urine output is usually associated with diuretic use or endocrine disorders rather than digoxin. Digoxin does not stimulate urine production, so polyuria would not indicate toxicity.

D. Bradycardia: Digoxin slows conduction through the AV node, and excessive levels can significantly depress heart rate. A notable drop in pulse can signal toxicity and requires immediate intervention to prevent dangerous arrhythmias.

Correct Answer is B

Explanation

The first image illustrates decerebrate posturing (also known as extensor posturing). In this more severe posture, the arms are rigidly extended and adducted, the wrists are pronated, the fingers are flexed, and the legs are rigidly extended with plantar flexion. This is caused by damage to the brainstem at or below the red nucleus (midbrain) and indicates a worse prognosis.

The second image illustrates decorticate posturing (also known as flexor posturing). In this posture, the client's arms are rigidly flexed and adducted (bent inward toward the chest), the fists are clenched, and the legs are extended and internally rotated. This is typically caused by damage to the corticospinal tracts above the red nucleus (above the midbrain).

A. Location A B. Location B C. Location C

Correct Answer is B

Explanation

Location A points to the eye area which is where conjunctival pallor (paleness) might be observed in anemia, but not cheilosis.
Cheilosis, or angular cheilitis, is a common clinical manifestation associated with iron-deficiency anemia, as well as deficiencies in B vitamins like riboflavin, pyridoxine and niacin. Location B points to the corners of the mouth (oral commissures). Cheilosis is characterized by the presence of fissures, scaling, and inflammation at these corners, where the lips meet.
Location C points to the nose which is unrelated to cheilosis.
