The nurse is aware that the major health complication associated with anorexia nervosa is:

Cardiac dysrhythmia resulting in cardiac arrest

Endocrine imbalance causing amenorrhea

Decreased metabolism causing cold intolerance

Glucose intolerance resulting in hypoglycemia

Answer and Explanation

The Correct Answer is A

a. Cardiac dysrhythmia resulting in cardiac arrest

Explanation of Choices

Choice A Reason: Cardiac Dysrhythmia Resulting in Cardiac Arrest

Cardiac dysrhythmias, or irregular heartbeats, are a significant health complication associated with anorexia nervosa. These dysrhythmias can result from electrolyte imbalances, particularly low potassium levels (hypokalemia), which are common in individuals with anorexia due to malnutrition and purging behaviors. Severe dysrhythmias can lead to cardiac arrest, making this one of the most critical and potentially fatal complications of anorexia nervosa. The heart muscle can weaken due to prolonged malnutrition, leading to a condition known as myocardial atrophy, which further increases the risk of cardiac complications.

Choice B Reason: Endocrine Imbalance Causing Amenorrhea

Amenorrhea, or the absence of menstruation, is a common endocrine complication in females with anorexia nervosa. This condition occurs due to the body’s response to severe weight loss and malnutrition, which disrupts the normal production of reproductive hormones. While amenorrhea is a significant health issue, it is not as immediately life-threatening as cardiac dysrhythmias. Amenorrhea can lead to long-term complications such as infertility and osteoporosis but does not typically result in acute medical emergencies.

Choice C Reason: Decreased Metabolism Causing Cold Intolerance

Decreased metabolism and cold intolerance are common symptoms in individuals with anorexia nervosa. The body reduces its metabolic rate in response to prolonged starvation to conserve energy. This can lead to a lower body temperature and increased sensitivity to cold. While uncomfortable and indicative of severe malnutrition, decreased metabolism and cold intolerance are not as immediately dangerous as cardiac dysrhythmias. These symptoms reflect the body’s adaptation to a state of energy deficiency but do not pose an immediate threat to life.

Choice D Reason: Glucose Intolerance Resulting in Hypoglycemia

Hypoglycemia, or low blood sugar, can occur in individuals with anorexia nervosa due to inadequate food intake. However, glucose intolerance and hypoglycemia are less common and less severe complications compared to cardiac dysrhythmias. Hypoglycemia can cause symptoms such as dizziness, confusion, and fainting, but it is typically manageable with appropriate nutritional support. It does not carry the same immediate risk of fatality as cardiac dysrhythmias.

Correct Answer is C

Explanation

The correct answer is c. Pepperoni pizza and red wine.

Choice A Reason:

Apple pie and coffee are generally safe to consume while taking MAOIs. These foods do not contain high levels of tyramine, which is the substance that can cause dangerous interactions with MAOIs. Tyramine is found in aged, fermented, or cured foods, and neither apple pie nor coffee falls into these categories.

Choice B Reason:

A bagel with cream cheese and tea is also considered safe for individuals taking MAOIs. Cream cheese is a fresh cheese and does not contain high levels of tyramine. Tea, while containing caffeine, does not pose a significant risk of tyramine interaction.

Choice C Reason:

Pepperoni pizza and red wine are high in tyramine and should be avoided by individuals taking MAOIs. Pepperoni is a cured meat, and red wine is a fermented beverage, both of which can lead to a hypertensive crisis when consumed with MAOIs. This combination can cause a dangerous spike in blood pressure, making it the correct answer to the question.

Choice D Reason:

Potato chips and diet cola do not contain high levels of tyramine and are generally safe to consume while taking MAOIs. Potato chips are not aged or fermented, and diet cola, although containing caffeine, does not pose a significant risk of tyramine interaction.

Correct Answer is ["10.5"]

Explanation

Step 1: Determine the concentration of insulin in the IV bag. 100 units of insulin are added to 150 mL of normal saline.

100 units ÷ 150 mL = (100 ÷ 150) = 0.6667 units per mL Result: 0.6667 units per mL

Step 2: Calculate the rate in mL per hour needed to deliver 7 units per hour. 7 units per hour ÷ 0.6667 units per mL = (7 ÷ 0.6667) = 10.5 mL per hour Result: 10.5 mL per hour

The correct rate for the nurse to set the IV pump is 10.5 mL per hour.
