Nursing Elites

1. 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.

2. A client has a new prescription for Digoxin. Which of the following instructions should the nurse provide?

• A. Monitor your heart rate before taking the medication.
• B. Increase your intake of high-potassium foods.
• C. Take the medication with a full glass of milk.
• D. Expect your stools to be black and tarry.

Correct answer: A

Rationale: Clients prescribed Digoxin should monitor their heart rate before each dose. This is essential to identify any potential bradycardia, defined as a heart rate below 60 bpm, which can be a side effect of Digoxin. Any significant changes in heart rate should be reported promptly to the healthcare provider for further evaluation and management. Choice B is incorrect because increasing intake of high-potassium foods can lead to hyperkalemia, a condition that can be exacerbated by Digoxin. Choice C is incorrect as taking Digoxin with a full glass of milk is not necessary. Choice D is incorrect as black, tarry stools are not an expected side effect of Digoxin.

3. A client has a prescription for Prednisone for the treatment of Rheumatoid Arthritis. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will increase my intake of potassium-rich foods.
• B. I should take my medication with food.
• C. I will decrease my intake of calcium-rich foods.
• D. I should avoid eating grapefruit while taking this medication.

Correct answer: A

Rationale: The correct answer is A. Prednisone can cause hypokalemia, leading to low potassium levels. Increasing the intake of potassium-rich foods helps prevent this imbalance. Choices B, C, and D are incorrect because taking Prednisone with food, decreasing calcium-rich foods, or avoiding grapefruit are not specifically related to addressing the side effect of hypokalemia associated with Prednisone.

4. A client has a new prescription for Folic Acid. Which of the following client statements indicates an understanding of the teaching?

• A. I will take this medication with food.
• B. I need to monitor for skin rash while taking this medication.
• C. I need to increase my intake of green, leafy vegetables.
• D. I will stop taking this medication if I feel nauseous.

Correct answer: C

Rationale: The correct answer is C. Folic acid is naturally found in green, leafy vegetables such as spinach and broccoli. Increasing the intake of these vegetables can supplement the prescribed folic acid and help maintain adequate levels in the body. It is essential to understand that dietary sources of folic acid can complement the medication and support overall health. Choices A, B, and D are incorrect because taking folic acid with food, monitoring for skin rash, or stopping the medication if feeling nauseous do not directly relate to enhancing the therapeutic effects of folic acid through dietary intake.

5. A client has a prescription for Furosemide. Which of the following instructions should the nurse include?

• A. Take the medication in the morning.
• B. Increase your intake of potassium-rich foods.
• C. Expect your urine to turn orange.
• D. Avoid prolonged sunlight exposure.

Correct answer: B

Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Furosemide is a loop diuretic that can lead to hypokalemia (low potassium levels) due to increased excretion of potassium in the urine. To counteract this effect and maintain electrolyte balance, the client should be advised to increase their intake of potassium-rich foods. This instruction helps prevent potential complications associated with low potassium levels. Choices A, C, and D are incorrect. Taking Furosemide in the morning does not affect its effectiveness; urine turning orange is not an expected side effect of Furosemide; and avoiding prolonged sunlight exposure is not directly related to Furosemide use.
