1. What is the classification of furosemide?

A. Loop diuretic
B. Anticoagulant
C. Iron supplement
D. Anticonvulsant

Correct answer: A

Rationale: Furosemide is classified as a loop diuretic, not an anticoagulant, iron supplement, or anticonvulsant. Loop diuretics, like furosemide, act in the loop of Henle in the kidney to inhibit sodium and chloride reabsorption, leading to increased urine output. This mechanism makes them effective in treating conditions such as edema and hypertension. Therefore, the correct classification for furosemide is a loop diuretic (Choice A).

2. Which statement is true about food and drug precautions?

A. Limiting certain types of food or administering certain types of drugs is necessary.
B. Certain combinations of food and drugs can cause adverse reactions.
C. Precautions may involve limiting certain types of food or administering drugs rather than restricting the drug itself.
D. When one drug alters the way another drug affects the body.

Correct answer: B

Rationale: The correct answer is B. Certain combinations of food and drugs can indeed lead to adverse reactions. It is important to be cautious with the simultaneous intake of food and drugs as interactions between them can affect their efficacy and safety. Choices A, C, and D are incorrect because they do not accurately reflect the potential risks associated with the combination of food and drugs.

3. A client with a urinary tract infection (UTI) is prescribed ciprofloxacin. Which instruction should the nurse provide to the client?

A. If the medication causes an upset stomach, take an antacid at the same time.
B. Increase your daily fluid intake while taking this medication.
C. This medication can cause photophobia, so avoid direct sunlight exposure.
D. You should report any tendon discomfort you experience while taking this medication.

Correct answer: D

Rationale: The correct answer is D. Tendon discomfort is a potential side effect of ciprofloxacin that can lead to tendon rupture and should be reported immediately to prevent serious complications. Monitoring for this adverse effect is crucial for patient safety. Choices A, B, and C are incorrect because: A) Taking an antacid with ciprofloxacin can interfere with its absorption. B) Increasing fluid intake is generally a good recommendation but not specifically related to the side effects of ciprofloxacin. C) Photophobia is not a common side effect of ciprofloxacin; therefore, avoiding direct sunlight exposure is not necessary.

4. A client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the nurse?

A. Perform immediate gastric lavage.
B. Prepare the client for hemodialysis.
C. Administer an additional oral dose of lithium.
D. Request a stat repeat of the laboratory test.

Correct answer: A

Rationale: In a client with a plasma lithium level of 2.1 mEq/L, immediate gastric lavage is appropriate for severe toxicity. Gastric lavage can help lower the client's lithium level by removing the unabsorbed lithium from the stomach.

5. A client is prescribed Amitriptyline for depression. What should the nurse include in the teaching? (Select all that apply.)

A. Expect therapeutic effects in 1-3 weeks.
B. Discontinue the medication gradually under healthcare provider supervision.
C. Change positions slowly to minimize dizziness.
D. Increase dietary fiber intake to prevent constipation.

Correct answer: C

Rationale: The correct answer is C. Changing positions slowly can help prevent orthostatic hypotension, a common adverse effect of tricyclic antidepressants like Amitriptyline. It is essential to educate the client to avoid sudden position changes to minimize the risk of dizziness and falls. Choices A, B, and D are incorrect. The therapeutic effects of Amitriptyline may not be noticeable for 1-3 weeks, so expecting them in 24 to 48 hours (choice A) is unrealistic. Discontinuing the medication abruptly can lead to withdrawal symptoms and should be done gradually under healthcare provider supervision, so choice B is incorrect. Amitriptyline can actually cause constipation, so increasing dietary fiber intake would be recommended to prevent constipation, making choice D incorrect.
