1. Which electrolyte imbalance is most concerning in a patient taking digoxin?

A. Monitor potassium levels
B. Monitor calcium levels
C. Monitor sodium levels
D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

2. What is the best intervention for a patient experiencing respiratory distress?

A. Administer oxygen
B. Administer bronchodilators
C. Administer IV fluids
D. Provide chest physiotherapy

Correct answer: A

Rationale: Administering oxygen is the best intervention for a patient experiencing respiratory distress because it helps improve oxygenation and alleviate respiratory distress. Oxygen therapy is crucial in ensuring that the patient receives an adequate supply of oxygen to meet the body's demands. Administering bronchodilators (Choice B) may be beneficial in specific respiratory conditions like asthma or COPD but may not be the primary intervention in all cases of respiratory distress. Administering IV fluids (Choice C) may be necessary in cases of dehydration or shock but would not directly address respiratory distress. Providing chest physiotherapy (Choice D) can help mobilize secretions in conditions like cystic fibrosis but is not the first-line intervention for respiratory distress.

3. A nurse is caring for a client who has cirrhosis. Which of the following laboratory findings should the nurse expect?

A. Increased bilirubin levels
B. Decreased albumin levels
C. Increased prothrombin time
D. Decreased serum glucose levels

Correct answer: A

Rationale: Corrected Rationale: Increased bilirubin levels are expected in clients with cirrhosis due to impaired liver function. Elevated bilirubin levels are commonly seen in cirrhosis as the liver's ability to process bilirubin is compromised. Decreased albumin levels and increased prothrombin time are also associated with cirrhosis, but the most specific finding related to liver dysfunction among the choices provided is increased bilirubin levels. Decreased serum glucose levels are not typically associated with cirrhosis.

4. A nurse is providing discharge teaching to a client who is recovering from a myocardial infarction. Which of the following client statements indicates a need for further teaching?

A. I will take a daily aspirin to prevent another heart attack.
B. I should expect to experience chest pain when I exercise.
C. I will increase my intake of saturated fats.
D. I will participate in a cardiac rehabilitation program.

Correct answer: C

Rationale: The correct answer is C. Increasing the intake of saturated fats can raise cholesterol levels, which is not recommended after a myocardial infarction. Choices A, B, and D are all appropriate statements indicating a good understanding of post-myocardial infarction care. Taking a daily aspirin can help prevent another heart attack, experiencing chest pain with exercise is a common expectation post-myocardial infarction, and participating in a cardiac rehabilitation program is important for recovery and improving heart health.

5. What is the best intervention for a patient with dehydration?

A. Administer IV fluids
B. Provide oral fluids
C. Encourage fluid intake
D. Administer electrolytes

Correct answer: A

Rationale: Administering IV fluids is the best intervention for a patient with dehydration because it is the fastest and most effective way to rehydrate the body. IV fluids can quickly restore fluid volume and electrolyte balance in severe cases of dehydration. Providing oral fluids or encouraging fluid intake may not be sufficient for patients with moderate to severe dehydration, as they may have impaired gastrointestinal absorption. While electrolytes are essential for rehydration, administering them alone without fluid replacement may not address the primary issue of fluid loss in dehydration.
