The nurse is reviewing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.16 seconds, and the QRS complexes measure 0.06 seconds. The overall heart rate is 64 beats/minute. Which would be a correct interpretation based on these characteristics?

Sinus bradycardia

Sinus arrhythmia

Sinus tachycardia

Normal sinus rhythm

Answer and Explanation

The Correct Answer is D

A. Sinus bradycardia: Sinus bradycardia is characterized by a regular rhythm with a heart rate less than 60 beats per minute. In this case, the heart rate is 64 beats per minute, which falls within the normal range, not consistent with sinus bradycardia.

B. Sinus arrhythmia: Sinus arrhythmia typically presents as a variation in the R-R interval with respiration, often seen as an irregularity in the heart rate. The provided characteristics describe a regular rhythm, so sinus arrhythmia is not the correct interpretation.

C. Sinus tachycardia: Sinus tachycardia is characterized by a regular rhythm with a heart rate greater than 100 beats per minute. The heart rate in this case is 64 beats per minute, which is not indicative of sinus tachycardia.

D. Normal sinus rhythm: Normal sinus rhythm refers to a regular rhythm with a heart rate between 60 and 100 beats per minute, P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and normal QRS complex duration (less than 0.12 seconds). The provided characteristics, including regular P waves, regular QRS complexes, a PR interval of 0.16 seconds, and a heart rate of 64 beats per minute, align with a normal sinus rhythm interpretation.

Correct Answer is ["B","C","D","E"]

Explanation

A. Take the medication with milk to increase absorption:

This statement is incorrect. Taking ferrous sulfate with milk or dairy products is not recommended as they can decrease iron absorption. It's advisable to take iron supplements with water or juice, preferably on an empty stomach or with a small amount of food.

B. Take the medication on an empty stomach:

This statement is partially correct. While taking ferrous sulfate on an empty stomach can enhance absorption, some individuals may experience gastrointestinal discomfort or irritation. Therefore, it's often recommended to take iron supplements with a small amount of food to minimize potential side effects.

C. Eat foods high in fiber while on this medication:

This statement is generally correct. Consuming foods high in fiber can help prevent constipation, which is a common side effect of iron supplements. Including fiber-rich foods in the diet, such as fruits, vegetables, whole grains, and legumes, can promote regular bowel movements.

D. Report stools that are dark in color immediately:

This statement is correct. Dark or black stools can indicate the presence of digested blood, which may occur due to iron supplementation. It's important to report such changes to the healthcare provider promptly for further evaluation.

E. Eating citrus fruit and juices are recommended with meals:

This statement is correct. Citrus fruits and juices, such as oranges, grapefruits, and lemon juice, contain vitamin C, which can enhance iron absorption. Consuming vitamin C-rich foods or drinks along with iron supplements can help improve iron uptake by the body.

A. numbness in extremities B. fatigue C. Shortness of breath D. anorexia E. Chest pain F. Confusion

Correct Answer is ["B","C","D","E","F"]

Explanation

A. Numbness in extremities: Numbness in extremities is not a common adverse effect of digoxin. The focus of digoxin monitoring is primarily on cardiovascular and gastrointestinal effects.

B. Fatigue: Fatigue is a common adverse effect of digoxin and can indicate toxicity or overdose. Clients taking digoxin should be monitored for increased fatigue or weakness.

C. Shortness of breath: Shortness of breath can occur as an adverse effect of digoxin toxicity, particularly if it leads to pulmonary congestion or heart failure exacerbation.

D. Anorexia: Anorexia, or loss of appetite, can be a gastrointestinal adverse effect of digoxin. Clients may experience nausea, vomiting, or anorexia, which can contribute to weight loss and electrolyte imbalances.

E. Chest pain: Chest pain can be a sign of digoxin toxicity, especially if it is associated with other symptoms such as shortness of breath or palpitations. It is essential to evaluate any chest pain in a client taking digoxin.

F. Confusion: Confusion or changes in mental status can occur with digoxin toxicity, particularly in older adults. Clients should be monitored for signs of confusion, delirium, or other cognitive changes.
