Nursing Elites

1. A healthcare professional is reviewing the medication list of a client who has a new prescription for Digoxin to treat heart failure. Which of the following medications places the client at risk for Digoxin toxicity?

• A. Spironolactone
• B. Calcium channel blockers
• C. Loop diuretics
• D. ACE inhibitors

Correct answer: C

Rationale: Loop diuretics, such as Furosemide, can increase the risk of Digoxin toxicity by causing hypokalemia. Hypokalemia enhances the toxic effects of Digoxin on the heart, leading to an increased risk of Digoxin toxicity. Spironolactone (Choice A) is less likely to cause hypokalemia and does not significantly increase the risk of Digoxin toxicity. Calcium channel blockers (Choice B) and ACE inhibitors (Choice D) do not directly increase the risk of Digoxin toxicity through hypokalemia; therefore, they are not the medications that place the client at risk for Digoxin toxicity.

2. A client has a new prescription for hydrochlorothiazide to treat hypertension. Which of the following instructions should be included?

• A. Take the medication in the morning.
• B. Increase intake of potassium-rich foods.
• C. Avoid sun exposure while taking this medication.
• D. Limit fluid intake to 1 liter per day.

Correct answer: B

Rationale: The correct instruction that should be included for a client prescribed hydrochlorothiazide is to increase the intake of potassium-rich foods. Hydrochlorothiazide, being a diuretic, can lead to hypokalemia by enhancing potassium excretion. Increasing consumption of potassium-rich foods like bananas or oranges can help prevent hypokalemia and maintain electrolyte balance. Choices A, C, and D are incorrect. Taking the medication in the morning is not a specific instruction related to hydrochlorothiazide. Avoiding sun exposure is more relevant for photosensitive medications, not hydrochlorothiazide. Limiting fluid intake to 1 liter per day is not necessary unless specifically advised by a healthcare provider.

3. In reviewing a client's health record, which condition would be a contraindication for using Propranolol to treat hypertension?

• A. Asthma
• B. Glaucoma
• C. Hypertension
• D. Tachycardia

Correct answer: A

Rationale: Propranolol is a nonselective beta-adrenergic blocker that blocks both beta1 and beta2 receptors. Blocking beta2 receptors in the lungs can lead to bronchoconstriction, making it unsuitable for clients with asthma. Therefore, asthma is a contraindication for taking Propranolol. Glaucoma, hypertension, and tachycardia are not contraindications for using Propranolol to treat hypertension.

4. When administering medications to a 4-month-old infant, which of the following pharmacokinetic principles should be considered? (Select all that apply.)

• A. Infants have a more rapid gastric emptying time.
• B. Infants have immature liver function.
• C. Infants' blood-brain barrier is poorly developed.
• D. Infants have an increased ability to absorb topical medications.

Correct answer: B

Rationale: When administering medications to a 4-month-old infant, the pharmacokinetic principle to consider is that infants have immature liver function until 1 year of age. This requires medications metabolized by the liver to be administered in smaller dosages. While infants do have a more rapid gastric emptying time, immature liver function is a more critical pharmacokinetic consideration in this context. Additionally, although infants have a poorly developed blood-brain barrier, this relates more to pharmacodynamic effects rather than pharmacokinetic principles. The statement about infants having an increased ability to absorb topical medications is not directly related to pharmacokinetic principles, making choice B the correct answer.

5. A client is being assessed by a healthcare provider while taking Digoxin to manage heart failure. Which of the following findings is a manifestation of digoxin toxicity?

• A. Bruising
• B. Report of metallic taste
• C. Muscle pain
• D. Report of anorexia

Correct answer: D

Rationale: The correct manifestation of digoxin toxicity is anorexia, not bruising, metallic taste, or muscle pain. Other symptoms of digoxin toxicity include blurred vision, stomach pain, and diarrhea. It is crucial for healthcare providers to promptly identify these signs to prevent severe complications.
