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 expresses fear of surgery. Which response should the nurse make?

A. Explain the risks of the surgery in detail.
B. Tell the client that many clients feel anxious before surgery.
C. Reassure the client that the surgical team is highly experienced.
D. Acknowledge the client's feelings and ask open-ended questions.

Correct answer: D

Rationale: When a client expresses fear of surgery, it is essential for the nurse to acknowledge their feelings and ask open-ended questions. This response shows empathy, validates the client's emotions, and encourages them to express their concerns further. Explaining the risks of the surgery in detail (Choice A) may increase the client's anxiety. Simply stating that many clients feel anxious before surgery (Choice B) does not address the client's specific fears. While reassuring the client about the surgical team's experience (Choice C) is important, it may not directly alleviate the client's fear.

3. A nurse is providing teaching to an older adult client about methods to promote nighttime sleep. Which of the following instructions should the nurse include?

A. Stay in bed for at least 1 hour if unable to fall asleep.
B. Take a 1-hour nap during the day.
C. Perform exercise before bed.
D. Eat a light snack before bedtime.

Correct answer: D

Rationale: The correct answer is to eat a light snack before bedtime. Consuming a light snack can help promote sleep by preventing discomfort from hunger. Choice A is incorrect because staying in bed for too long when unable to fall asleep can lead to frustration and worsen insomnia. Choice B is incorrect as taking a nap during the day can interfere with nighttime sleep. Choice C is incorrect as exercising before bed can increase alertness and make falling asleep more difficult.

4. A nurse is providing dietary teaching to a client with irritable bowel syndrome (IBS). Which dietary recommendation should be included?

A. Consume food high in bran fiber.
B. Increase intake of milk products.
C. Sweeten foods with fructose corn syrup.
D. Increase foods high in gluten.

Correct answer: A

Rationale: The correct answer is A: Consume food high in bran fiber. Bran fiber helps reduce IBS symptoms by promoting regular bowel movements. Choices B, C, and D are incorrect because increasing milk products can exacerbate symptoms in some individuals with IBS, sweetening foods with fructose corn syrup may worsen symptoms due to its high FODMAP content, and increasing foods high in gluten could be problematic for individuals with gluten sensitivities or celiac disease, which are common in some with IBS.

5. A nurse is performing a gastric lavage for a client who has upper gastrointestinal bleeding. Which of the following actions should the nurse take?

A. Instill 500 ml of solution through the NG tube
B. Insert a large-bore NG tube
C. Use a cold irrigation solution
D. Instruct the client to lie on his right side

Correct answer: B

Rationale: The correct answer is B: 'Insert a large-bore NG tube.' When performing a gastric lavage for a client with upper gastrointestinal bleeding, a large-bore NG tube is used to effectively remove gastric contents and blood. Option A is incorrect because the amount of solution to instill depends on the specific situation and should be guided by the healthcare provider's order. Option C is incorrect because using a cold irrigation solution can lead to hypothermia and is not recommended. Option D is incorrect as there is no need to instruct the client to lie on his right side specifically for gastric lavage.
