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. A client with chronic kidney disease is receiving dietary teaching from a nurse. Which of the following client statements indicates an understanding of the teaching?

A. I will increase my intake of bananas.
B. I will limit my intake of foods high in potassium.
C. I will increase my intake of protein-rich foods.
D. I will increase my intake of dairy products.

Correct answer: B

Rationale: The correct answer is B. Limiting potassium-rich foods is crucial for clients with chronic kidney disease to prevent hyperkalemia, a common complication. Increasing intake of potassium-rich foods like bananas (choice A), protein-rich foods (choice C), or dairy products (choice D) can exacerbate hyperkalemia in these clients. Bananas, protein-rich foods, and dairy products are all high in potassium, which is detrimental for individuals with chronic kidney disease. Therefore, choices A, C, and D are incorrect.

3. A nurse is providing discharge teaching to a client who has chronic kidney disease and is receiving hemodialysis. What dietary instruction should the nurse provide?

A. Take magnesium hydroxide for indigestion.
B. Drink at least 3L of fluid daily.
C. Eat 1g/kg of protein per day.
D. Consume foods high in potassium.

Correct answer: C

Rationale: For a client with chronic kidney disease receiving hemodialysis, consuming 1g/kg of protein per day is important. This amount helps manage the condition without overburdening the kidneys. Choice A is incorrect because magnesium hydroxide is not specifically recommended for clients with chronic kidney disease. Choice B is not accurate as fluid intake needs to be individualized based on the client's condition and dialysis status. Choice D is incorrect because foods high in potassium should generally be limited for individuals with kidney disease undergoing hemodialysis to prevent hyperkalemia.

4. What is the best intervention for a patient experiencing hypoxia?

A. Administer oxygen
B. Reposition the patient
C. Provide humidified air
D. Provide chest physiotherapy

Correct answer: A

Rationale: The best intervention for a patient experiencing hypoxia is to administer oxygen. Oxygen therapy helps improve oxygenation levels in the blood, addressing the underlying cause of hypoxia. Repositioning the patient, providing humidified air, and chest physiotherapy may be beneficial in certain situations but are not the primary interventions for hypoxia. Administering oxygen is crucial to quickly alleviate hypoxia and support the patient's respiratory function.

5. A nurse is providing teaching to a client who is experiencing preterm contractions and dehydration. Which of the following statements should the nurse make?

A. Dehydration is treated with calcium supplements
B. Dehydration can increase the risk of preterm labor
C. Dehydration can increase gastroesophageal reflux
D. Dehydration is caused by a decreased hemoglobin and hematocrit

Correct answer: B

Rationale: The correct statement the nurse should make is that dehydration can increase the risk of preterm labor. Dehydration reduces amniotic fluid and uterine blood flow, potentially leading to preterm contractions. Choice A is incorrect because dehydration is not treated with calcium supplements but rather with adequate fluid intake. Choice C is incorrect as dehydration does not directly increase gastroesophageal reflux. Choice D is incorrect as dehydration is not caused by decreased hemoglobin and hematocrit levels but rather by insufficient fluid intake or excessive fluid loss.
