A nurse in a provider's office is reviewing the laboratory results of four clients who take digoxin.
Which of the following clients is at risk for developing digoxin toxicity?
A client who takes glyburide for type 2 diabetes mellitus.
A client who takes furosemide for hypertension.
A client who takes cimetidine to reduce gastric acid secretion.
A client who takes azelastine for allergic rhinitis.
The Correct Answer is B
Choice A rationale:
A client who takes glyburide for type 2 diabetes mellitus is not at significant risk for developing digoxin toxicity. Glyburide is an antidiabetic medication and does not interact directly with digoxin.
Choice B rationale: Furosemide, a loop diuretic, can cause electrolyte imbalances such as hypokalemia (normal potassium levels: 3.5 to 5.0 mEq/L) and hypomagnesemia (normal magnesium levels: 1.7 to 2.2 mg/dL). These imbalances increase the sensitivity to digoxin and the risk of toxicity. Digoxin toxicity is associated with symptoms like nausea, vomiting, and arrhythmias. Furosemide's impact on electrolytes makes it a significant risk factor for digoxin toxicity.
Choice C rationale: Cimetidine, a histamine H2 receptor antagonist, can inhibit the metabolism of certain drugs by affecting liver enzymes. However, it does not significantly alter digoxin levels or increase the risk of toxicity. Normal liver enzyme levels include ALT (7 to 56 U/L) and AST (10 to 40 U/L). While cimetidine may interact with other medications, its effect on digoxin is minimal.
Choice D rationale:
A client who takes azelastine for allergic rhinitis is not at significant risk for developing digoxin toxicity. Azelastine is an antihistamine and does not interact directly with digoxin.

Correct Answer is C
Explanation
Choice A rationale:
"Fresh fruits are good to include with meals.”. Including fresh fruits with meals is an excellent choice for a heart-healthy diet. Fresh fruits are rich in essential vitamins, minerals, and fiber, which can help lower blood pressure and reduce the risk of heart disease.
Choice B rationale:
"I will replace table salt with dried herbs.”. This is a good choice for reducing sodium intake. Dried herbs can add flavor to food without the need for table salt, which is high in sodium. Lowering sodium intake is crucial for individuals with hypertension to manage their condition and maintain a heart-healthy diet.
Choice C rationale:
"I can have a cola drink twice a day.”. This choice is incorrect. Consuming cola drinks, which are high in sugar and caffeine, is not advisable for individuals with hypertension. High sugar intake can contribute to weight gain and high blood pressure, while caffeine can temporarily raise blood pressure. Clients with hypertension should limit or avoid soda consumption.
Choice D rationale:
"I can eat frozen juice bars for a snack.”. Frozen juice bars can be a healthier alternative to high-calorie, sugary snacks. However, the specific content of these bars should be considered. If they contain added sugars or high levels of sodium, it may not be the best choice. Clients with hypertension should focus on snacks that are low in added sugars and salt.
Correct Answer is A
Explanation
Choice A rationale:
Hypovolemic shock is characterized by a decrease in blood volume, leading to low blood pressure and compensatory mechanisms such as a high pulse rate. When the body experiences a significant loss of blood or fluid, it attempts to maintain perfusion to vital organs by increasing the heart rate to ensure an adequate blood supply. Low blood pressure and a high pulse rate are classic signs of hypovolemic shock.
Choice B rationale:
A low BP and low pulse rate are not indicative of hypovolemic shock. Hypovolemic shock is associated with a rapid and weak pulse rate as the body tries to compensate for decreased blood volume. A low pulse rate could suggest other conditions, such as bradycardia, rather than hypovolemic shock.
Choice C rationale:
High BP and high pulse rate are not typical findings in hypovolemic shock. Hypovolemic shock is characterized by low blood pressure and a high pulse rate as the body attempts to compensate for the reduced blood volume. High blood pressure is more commonly associated with conditions like hypertension, not hypovolemic shock.
Choice D rationale:
High BP and low pulse rate are not consistent with the characteristics of hypovolemic shock. As mentioned earlier, hypovolemic shock is marked by low blood pressure and a high pulse rate due to the body's efforts to maintain adequate perfusion. High blood pressure and a low pulse rate may suggest other medical conditions unrelated to hypovolemic shock.
