A nurse is collecting data from a client prior to administering metoprolol. For which of the following findings should the nurse withhold the medication?

A. A patient with coronary artery disease (CAD) who reports chest pain radiating to the jaw: This patient should be evaluated first. Chest pain radiating to the jaw can be a sign of a heart attack, which is a life-threatening condition. Immediate medical attention is required to prevent further damage to the heart muscle.

B. A patient with venous insufficiency with 2+ pitting edema: While this patient’s condition needs to be addressed, it is not as immediately life-threatening as a potential heart attack. Venous insufficiency and edema can lead to discomfort and complications if left untreated, but these complications are typically not immediate.

C. A patient receiving enoxaparin (Lovenox) for experiencing an MI 3 days ago: This patient is already receiving treatment for their condition. While they should be monitored for side effects of the medication and signs of further cardiac issues, they are not the highest priority based on the information given.

D. A patient with peripheral artery disease (PAD) with a diminished pulse: While a diminished pulse can indicate poor blood flow, which can lead to complications such as tissue damage and non-healing wounds, it is not as immediately life-threatening as a potential heart attack. This patient should be evaluated, but they are not the highest priority based on the information given.

(A) Diarrhea: Diarrhea is typically associated with gastrointestinal disorders. It involves frequent loose or watery stools, which is not a symptom of respiratory alkalosis. Respiratory alkalosis is a condition that affects the respiratory system, causing an increase in the rate or depth of respiration, leading to a decrease in the concentration of carbon dioxide in the blood.

(B) Hyperventilation: Hyperventilation is indeed a common finding in respiratory alkalosis. When a person hyperventilates, they breathe out more carbon dioxide than their body produces. This lowers the level of carbon dioxide in the blood, leading to a rise in blood pH and causing the blood to become more alkaline - a state known as alkalosis.

(C) Dry skin: Dry skin is not typically associated with respiratory alkalosis. It’s more common in conditions like dehydration or skin disorders. Respiratory alkalosis is a condition that affects the respiratory system and the balance of acids and bases in the blood, not the skin.

(D) Abdominal pain: Abdominal pain is not typically associated with respiratory alkalosis. It’s more common in gastrointestinal disorders. Respiratory alkalosis is a condition that affects the respiratory system and the balance of acids and bases in the blood, not the digestive system.
