Nursing Elites

1. A healthcare provider is reviewing the health care record of a client who reports urinary incontinence and asks about a prescription for Oxybutynin. The healthcare provider should recognize that Oxybutynin is contraindicated in the presence of which of the following conditions?

• A. Bursitis
• B. Sinusitis
• C. Depression
• D. Glaucoma

Correct answer: D

Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma due to the potential to worsen the condition by further elevating intraocular pressure, leading to harm. Choosing option D, Glaucoma, as the correct answer is crucial for the client's safety and to prevent exacerbation of their eye condition. Options A, B, and C are not contraindications for Oxybutynin use and are unrelated to the pharmacological effects of this medication.

2. A client with Hodgkin's disease is receiving Cyclophosphamide IV. Which medication should be administered concurrently to prevent an adverse effect of Cyclophosphamide?

• A. Uroprotectant agent, such as mesna
• B. Opioid, such as morphine
• C. Loop diuretic, such as furosemide
• D. H1 receptor antagonist, such as diphenhydramine

Correct answer: A

Rationale: Mesna, an uroprotectant agent, is administered with nitrogen mustard chemotherapy drugs like Cyclophosphamide to prevent hemorrhagic cystitis, a common adverse effect. Mesna works by binding to and inactivating the toxic metabolites of Cyclophosphamide in the bladder, thereby reducing the risk of bladder toxicity.

3. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

• A. Spironolactone
• B. Furosemide
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.

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. A nurse is teaching a client who has a new prescription for Atenolol. Which of the following adverse effects should the nurse instruct the client to monitor?

• A. Tachycardia
• B. Hypoglycemia
• C. Bradycardia
• D. Hypertension

Correct answer: C

Rationale: Atenolol is a beta-blocker that can cause bradycardia as an adverse effect. The client should monitor their pulse regularly and report any significant decreases.
