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 Nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. Take one tablet every 15 minutes until pain is relieved.
• B. Take one tablet every 5 minutes, up to three doses.
• C. Take one tablet at bedtime.
• D. Take one tablet on an empty stomach.

Correct answer: B

Rationale: The correct administration of Nitroglycerin sublingual tablets involves taking one tablet at the onset of chest pain and repeating every 5 minutes for up to three doses. This protocol helps in managing angina episodes effectively. Choice A suggests taking a tablet every 15 minutes until pain relief, which may delay appropriate intervention. Choice C, taking a tablet at bedtime, is not suitable for immediate relief during angina attacks. Choice D, taking a tablet on an empty stomach, is unrelated to the correct administration of Nitroglycerin sublingual tablets.

3. A healthcare professional reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the professional take?

• A. Obtain a blood specimen immediately prior to administering the next dose of medication.
• B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
• C. Ask the client to provide a urine specimen after the next dose of medication.
• D. Administer the medication, and obtain a blood specimen 30 minutes later.

Correct answer: A

Rationale: To verify trough levels of a medication, the healthcare professional should obtain a blood specimen immediately before administering the next dose of medication. This timing ensures an accurate representation of the medication's lowest concentration in the bloodstream, which is crucial for therapeutic monitoring and dose adjustments. Choice B is incorrect because waiting 24 hours after taking the medication would not provide an accurate trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect because obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level, as it is the lowest concentration before the next dose.

4. What is pharmacodynamics?

• A. The medical reference summarizing standards of drug purity, strength, and directions for synthesis
• B. The drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions
• C. The maximum response that a drug can produce
• D. Movements of the drugs throughout the body

Correct answer: B

Rationale: Pharmacodynamics refers to the drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions. It involves understanding how drugs interact with the body at the molecular level to produce their effects, including mechanisms of action, receptor binding, and downstream physiological responses. Choice A is incorrect because it describes pharmacopeia, which is a reference book containing standards for drugs. Choice C refers to efficacy, which is the maximum effect a drug can produce. Choice D describes pharmacokinetics, which focuses on the movement of drugs within the body.

5. A nurse is teaching a client who has a new prescription for Prednisone. Which of the following instructions should the nurse include?

• A. Increase your intake of vitamin
• B. Take this medication on an empty stomach.
• C. Avoid drinking grapefruit juice.
• D. Take this medication every other day.

Correct answer: A

Rationale: Prednisone can lead to bone loss, so clients should increase their intake of vitamin D and calcium to help maintain bone health.
