Nursing Elites

1. A client who is receiving digoxin (Lanoxin) daily has a serum potassium level of 3.0 mEq/L and is complaining of anorexia. A healthcare provider prescribes a digoxin level to rule out digoxin toxicity. A nurse checks the results, knowing that which of the following is the therapeutic serum level (range) for digoxin?

• A. 3 to 5 ng/mL
• B. 0.5 to 2 ng/mL
• C. 1.2 to 2.8 ng/mL
• D. 3.5 to 5.5 ng/mL

Correct answer: B

Rationale: The therapeutic serum level for digoxin ranges from 0.5 to 2 ng/mL. This range is considered optimal for therapeutic effects while minimizing the risk of toxicity. Levels above 2 ng/mL may lead to digoxin toxicity, which can manifest as anorexia among other symptoms. Therefore, the nurse should be vigilant in monitoring the digoxin levels to ensure the client's safety and therapeutic effectiveness of the medication.

2. A client with a prescription to take theophylline (Theo-24) daily has been given medication instructions by the nurse. The nurse determines that the client needs further information about the medication if the client states that he or she will:

• A. Drink at least 2 L of fluid per day.
• B. Take the daily dose at bedtime.
• C. Avoid changing brands of the medication without health care provider (HCP) approval.
• D. Avoid over-the-counter (OTC) cough and cold medications unless approved by the HCP.

Correct answer: B

Rationale: The correct answer is B. Taking theophylline at bedtime is inappropriate because it can cause insomnia. The medication should be taken early in the morning to avoid disrupting sleep patterns. It is important to follow the healthcare provider's instructions regarding the timing of the medication to achieve optimal therapeutic effects.

3. Prednisone is prescribed for a client with diabetes mellitus who is taking Humulin neutral protamine Hagedorn (NPH) insulin daily. Which of the following prescription changes does the nurse anticipate during therapy with prednisone?

• A. An additional dose of prednisone daily
• B. A decreased amount of daily Humulin NPH insulin
• C. An increased amount of daily Humulin NPH insulin
• D. The addition of an oral hypoglycemic medication daily

Correct answer: C

Rationale: When prednisone is prescribed for a client with diabetes mellitus who is taking Humulin NPH insulin daily, the nurse should anticipate an increased amount of daily Humulin NPH insulin. Prednisone, a glucocorticoid, can elevate blood glucose levels, requiring an increase in insulin dosage to maintain optimal blood sugar control.

4. When monitoring a client for acute toxicity associated with bethanechol chloride (Urecholine), what sign should the nurse check for to indicate toxicity?

• A. Dry skin
• B. Dry mouth
• C. Bradycardia
• D. Signs of dehydration

Correct answer: C

Rationale: The correct answer is C: Bradycardia. Toxicity from bethanechol chloride (Urecholine) can lead to excessive muscarinic stimulation, resulting in manifestations like salivation, sweating, involuntary urination and defecation, bradycardia, and severe hypotension. When facing toxicity, treatment involves supportive measures and administering atropine sulfate subcutaneously or intravenously.

5. A client with chronic pain is prescribed transdermal fentanyl (Duragesic) patches. Which instruction should the nurse include in the teaching plan?

• A. Apply the patch to a different site each time.
• B. Avoid using heating pads over the patch.
• C. Change the patch every 72 hours.
• D. Remove the old patch before applying the new one.

Correct answer: B

Rationale: Clients using transdermal fentanyl (Duragesic) patches should avoid using heating pads over the patch as heat can increase the release of the medication, potentially leading to overdose. The patch should be applied to a different site each time, changed every 72 hours, and the old patch should be removed before applying a new one to prevent accidental overdose or excessive drug absorption.
