Nursing Elites

1. A healthcare provider in a clinic is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?

• A. Calcium 9.2 mg/dL
• B. Calcium 10.3 mg/dL
• C. Potassium 3.4 mEq/L
• D. Potassium 4.8 mEq/L

Correct answer: C

Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Hypokalemia potentiates the effects of Digoxin, making the heart more sensitive to its toxic effects. Monitoring and correcting electrolyte imbalances, especially low potassium levels, are crucial to prevent adverse effects of digoxin therapy. Calcium levels do not directly influence digoxin toxicity, so choices A and B are incorrect. High potassium levels, as in choice D, are less likely to increase the risk of digoxin toxicity compared to low potassium levels.

2. Which of the following is classified as a class IA Sodium Channel blocker?

• A. Quinidine
• B. Disopyramide
• C. Aminodarone
• D. Propafenone

Correct answer: A

Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.

3. A client has a new prescription for Furosemide. What instruction should be included by the nurse during discharge?

• A. Take the medication at bedtime.
• B. Increase intake of foods high in potassium.
• C. Avoid sun exposure.
• D. Limit fluid intake.

Correct answer: B

Rationale: The correct answer is to instruct the client to increase intake of foods high in potassium. Furosemide, a loop diuretic, can lead to potassium depletion. Increasing the intake of foods rich in potassium can help prevent hypokalemia, a potential side effect of Furosemide. Choice A is incorrect as Furosemide is usually recommended to be taken in the morning to avoid disrupting sleep with frequent urination. Choice C is irrelevant to the medication. Choice D is also incorrect as Furosemide is a diuretic and may require increased, not limited, fluid intake to prevent dehydration.

4. A client has a prescription for Desmopressin for the treatment of Diabetes Insipidus. Which of the following instructions should the nurse include in the teaching?

• A. Decrease fluid intake at the start of treatment.
• B. Monitor for nocturia.
• C. Report a weight loss of 0.5 kg (1.1 lb) per week.
• D. Expect permanent polyuria with this medication.

Correct answer: A

Rationale: Desmopressin is a medication used to reduce diuresis in clients with diabetes insipidus. To prevent water intoxication, clients should be advised to decrease fluid intake at the beginning of treatment. This instruction helps to balance fluid levels in the body and prevent potential complications associated with excessive fluid intake while on Desmopressin therapy. Monitoring for signs of fluid retention, such as weight gain, and adjusting fluid intake accordingly are essential components of client education when initiating treatment with Desmopressin.

5. A healthcare professional is preparing to administer Filgrastim for the first time to a client who has just undergone a bone marrow transplant. Which of the following interventions is appropriate?

• A. Administer intravenously to prevent injury.
• B. Ensure that the medication is kept refrigerated until just prior to administration.
• C. Do not shake the vial; gently invert it to mix before withdrawing the dose.
• D. Discard the vial after removing one dose of the medication.

Correct answer: D

Rationale: When administering Filgrastim, only one dose should be withdrawn from the vial, and the vial should then be discarded to prevent any contamination or errors in dosing. It is crucial not to shake the vial but gently invert it to mix the medication before withdrawing the appropriate dose. Refrigeration is not required for Filgrastim; it should be stored at room temperature until just before administration. Choice A is incorrect because Filgrastim is typically administered subcutaneously, not intravenously. Choice B is incorrect as the medication should be stored at room temperature, not refrigerated, until administration. Choice C is incorrect as shaking the vial is not recommended for Filgrastim.
