1. What is the therapeutic classification of Furosemide?

A. Antidiuretics
B. Diuretics
C. Anticonvulsants
D. Antidotes

Correct answer: B

Rationale: Furosemide is classified therapeutically as a diuretic. Diuretics are medications used to promote diuresis, which helps the body get rid of excess salt and water. Furosemide is commonly prescribed to treat conditions such as fluid retention and swelling (edema) associated with congestive heart failure, liver disease, or kidney disorders. Choice A, Antidiuretics, is incorrect as Furosemide acts as a diuretic, promoting the production of urine. Choice C, Anticonvulsants, is also incorrect as Furosemide is not used to treat seizures. Choice D, Antidotes, is incorrect as Furosemide is not an antidote but rather a medication used to treat conditions related to fluid retention.

2. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?

A. Use a blood pressure cuff to distend the veins.
B. Select the antecubital area to insert the IV catheter.
C. Distend the veins by using a blood pressure cuff.
D. Direct the client to lower his arm below his heart.

Correct answer: C

Rationale: The correct answer is C. The healthcare professional should distend the veins using a blood pressure cuff to make the veins more visible and accessible for IV catheter insertion. This technique helps reduce the risk of overfilling the vein, which can lead to complications such as hematoma formation. Choices A, B, and D are incorrect because while selecting the antecubital area is often appropriate for IV insertion in adults, the key action in this scenario is to distend the veins using a blood pressure cuff to facilitate the procedure.

3. Which of the following conditions is not treated with Prednisone?

A. Cushing’s disease
B. Testicular cancer
C. Lymphomas
D. Chronic leukemias

Correct answer: B

Rationale: Prednisone is not a common treatment for testicular cancer. Prednisone is used in conditions like Cushing’s disease, lymphomas, and chronic leukemias due to its anti-inflammatory and immunosuppressive properties. However, testicular cancer treatment typically involves surgery, chemotherapy, and radiation therapy, but not Prednisone.

4. When teaching a client about preventing Otitis Externa, which of the following instructions should the nurse include?

A. Clean the ear with a cotton-tipped swab daily.
B. Place earplugs in the ears when sleeping at night.
C. Use a cool water irrigation solution to remove earwax.
D. Tip the head to the side to remove water from the ears after showering.

Correct answer: D

Rationale: To prevent Otitis Externa, the nurse should instruct the client to tip the head to the side to allow water to drain out after showering or swimming. This helps to prevent moisture buildup in the ear canal, reducing the risk of developing Otitis Externa, commonly known as swimmer's ear.

5. Which medication is a beta blocker?

A. Atenolol (Tenormin)
B. Verapamil (Calan)
C. Captopril (Capoten)
D. Clopidogrel (Plavix)

Correct answer: A

Rationale: Atenolol (Tenormin) is a beta blocker commonly used to treat conditions like hypertension and angina by blocking the action of adrenaline on the heart. Verapamil is a calcium channel blocker, Captopril is an ACE inhibitor, and Clopidogrel is an antiplatelet medication. Therefore, the correct answer is Atenolol (Tenormin) as it belongs to the beta blocker class of medications.
