Which instruction by the nurse will be included when teaching an adult patient about digoxin (Lanoxin) for management of heart failure?
Report nausea and vomiting to your health care provider.
Auditory hallucinations are common adverse effects.
Decrease the amount of high-potassium foods you eat.
Omit your dose of digoxin if your pulse is 70.
The Correct Answer is A
Choice A reason: This is the correct instruction by the nurse. Nausea and vomiting are signs of digoxin toxicity, which can be life-threatening. The patient should report these symptoms to their health care provider as soon as possible and have their digoxin level checked.
Choice B reason: This is not a correct instruction by the nurse. Auditory hallucinations are not common adverse effects of digoxin. They are more likely to occur with other drugs, such as antipsychotics or opioids.
Choice C reason: This is not a correct instruction by the nurse. Decreasing the amount of high-potassium foods can increase the risk of digoxin toxicity, as potassium competes with digoxin for binding sites on the cardiac cells. The patient should maintain a normal potassium intake and avoid sudden changes in their diet.
Choice D reason: This is not a correct instruction by the nurse. Omitting the dose of digoxin if the pulse is 70 can lead to underdosing and ineffective treatment of heart failure. The patient should only omit the dose of digoxin if their pulse is below 60, as this indicates bradycardia, which is another sign of digoxin toxicity.

Correct Answer is B
Explanation
Choice A reason: This is not the definition of ejection fraction. The percentage of blood that leaves the heart in a minute is related to the cardiac output, which is the product of the heart rate and the stroke volume.
Choice B reason: This is the correct definition of ejection fraction. It is the ratio of the stroke volume (the amount of blood pumped by the left ventricle) to the end-diastolic volume (the amount of blood in the left ventricle at the end of diastole). It is a measure of the efficiency of the heart and reflects the contractility of the cardiac muscle.
Choice C reason: This is not the definition of ejection fraction. The amount of blood that leaves the heart with each beat is the stroke volume, which is one of the factors that determine the ejection fraction.
Choice D reason: This is not the definition of ejection fraction. The amount of blood that leaves the heart in a minute is the cardiac output, which is influenced by the ejection fraction, but not equivalent to it.
Correct Answer is ["A","C","D","E"]
Explanation
Choice A reason: Use of accessory breathing muscles is a sign of respiratory distress and increased work of breathing. Accessory muscles are the muscles of the neck, chest, and abdomen that assist the diaphragm and intercostal muscles in breathing. They are normally not used for breathing, but they are recruited when the airway is obstructed or the lung function is impaired.
Choice B reason: Foul-smelling sputum is not a sign of an acute asthma episode. It is a sign of a bacterial infection or a lung abscess. Sputum is the mucus that is coughed up from the lungs. It can have different colors, textures, and odors depending on the cause and severity of the condition.
Choice C reason: Feeling of chest tightness is a sign of an acute asthma episode. It is caused by the bronchoconstriction, or the narrowing of the airways, that occurs during an asthma attack. It can also be accompanied by pain or pressure in the chest.
Choice D reason: Coughing is a sign of an acute asthma episode. It is a reflex action that tries to clear the airways of mucus, irritants, or foreign particles. It can also be triggered by the inflammation and hypersensitivity of the airways that occur during an asthma attack.
Choice E reason: Expiratory wheezing is a sign of an acute asthma episode. It is a high-pitched whistling sound that is heard when the person exhales. It is caused by the turbulent flow of air through the narrowed airways. It can also be heard on inspiration, but it is more prominent on expiration.
