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. What is the antidote for copper toxicity?

A. Glucagon
B. Aminocaproic acid
C. Atropine
D. Penicillamine

Correct answer: D

Rationale: Penicillamine is the specific chelating agent used for copper toxicity. It forms stable complexes with copper, which are then excreted in the urine. Glucagon is used for treating hypoglycemia, aminocaproic acid is used to treat bleeding disorders, and atropine is used as an antidote for certain types of poisoning, such as organophosphate toxicity.

3. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?

A. Taking four medications decreases the risk of a severe allergic reaction.
B. Taking four medications reduces the chance that the bacteria will become resistant.
C. Taking four medications reduces the risk of adverse reactions.
D. Taking four medications decreases the chance of having a positive tuberculin skin test.

Correct answer: B

Rationale: When treating tuberculosis, using a combination of multiple medications is crucial to reduce the risk of bacterial resistance. The use of four medications helps to target the bacteria from different angles, making it harder for them to develop resistance to the treatment. This approach is essential to ensure the effectiveness of the treatment regimen and to prevent the spread of drug-resistant strains of tuberculosis. Choices A, C, and D are incorrect because the primary reason for using multiple medications in tuberculosis treatment is to prevent the development of bacterial resistance, not to decrease the risk of allergic reactions, adverse reactions, or affecting the tuberculin skin test results.

4. A client has a new prescription for Iron supplements. Which of the following instructions should be included?

A. Take the medication with a glass of milk.
B. Avoid taking the medication with orange juice.
C. Increase fiber intake to prevent constipation.
D. Expect stools to be bright red.

Correct answer: C

Rationale: The correct answer is C: 'Increase fiber intake to prevent constipation.' Iron supplements commonly cause constipation as a side effect. Increasing fiber intake can help alleviate this issue by promoting regular bowel movements and preventing constipation. Choice A is incorrect as iron absorption is hindered when taken with milk. Choice B is not directly related to iron supplements. Choice D is incorrect as iron supplements do not typically cause bright red stools.

5. A healthcare professional is preparing to administer Haloperidol 2 mg PO every 12 hr. The available medication is haloperidol 1 mg/tablet. How many tablets should the healthcare professional administer?

A. 1 tablet
B. 2 tablets
C. 3 tablets
D. 4 tablets

Correct answer: B

Rationale: To calculate the number of tablets needed, divide the desired dose by the dose per tablet. In this case, (2 mg / 1 mg/tablet) = 2 tablets required to administer the correct dosage of Haloperidol.
