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 is being taught about a new prescription for Escitalopram to treat generalized anxiety disorder. Which statement by the client indicates understanding of the teaching?

• A. I should take the medication with food.
• B. I will monitor my blood sugar levels while taking this medication.
• C. I need to discontinue this medication slowly.
• D. I can crush this medication before swallowing.

Correct answer: C

Rationale: The correct answer is C. When discontinuing Escitalopram, the client should taper the medication slowly according to a prescribed dosing schedule to reduce the risk of withdrawal syndrome. Abruptly stopping the medication can lead to withdrawal symptoms, so it is important to follow the healthcare provider's instructions for gradual discontinuation. Choices A, B, and D are incorrect because Escitalopram should not necessarily be taken with food, there is no direct correlation with blood sugar levels, and the medication should not be crushed before swallowing.

3. A client has a new prescription for Albuterol and Beclomethasone inhalers for the control of asthma. Which of the following instructions should the nurse include in the teaching?

• A. Take the albuterol at the same time each day.
• B. Administer the albuterol inhaler prior to using the beclomethasone inhaler.
• C. Use beclomethasone if experiencing an acute episode.
• D. Avoid shaking the beclomethasone before use.

Correct answer: B

Rationale: When a client is prescribed an inhaled beta2-agonist, such as albuterol, and an inhaled glucocorticoid, such as beclomethasone, for asthma control, the beta2-agonist should be administered first. This sequence is important because the beta2-agonist promotes bronchodilation, which enhances the absorption and effectiveness of the glucocorticoid. Instructing the client to administer the albuterol inhaler before using the beclomethasone inhaler ensures optimal therapeutic benefit. Therefore, option B is the correct choice. Option A is incorrect because the timing of albuterol administration may vary based on the prescribed regimen. Option C is incorrect because beclomethasone is a controller medication, not a rescue medication, and should not be used during acute episodes. Option D is incorrect because beclomethasone should be shaken before use to ensure proper dispersion of the medication.

4. The client with angina is being discharged to home. The nurse is instructing the client on dietary changes. What should be included in this teaching?

• A. Decrease salt and fat intake and limit alcohol intake.
• B. There are no dietary restrictions for a person diagnosed with angina.
• C. Limit smoking and increase protein and sugar intake.
• D. Increase fruits, vegetables, and foods high in cholesterol.

Correct answer: A

Rationale: The correct answer is to decrease salt and fat intake and limit alcohol intake. These dietary changes can help manage angina by reducing the workload on the heart and preventing further plaque buildup in the arteries. Choices B, C, and D are incorrect as dietary restrictions for angina typically involve reducing salt, fat, and alcohol intake, rather than increasing sugar or cholesterol intake.

5. A client with heart failure is being instructed on laxative use. Which of the following laxatives should the client avoid?

• A. Sodium phosphate
• B. Psyllium
• C. Bisacodyl
• D. Polyethylene glycol

Correct answer: A

Rationale: The correct answer is A: Sodium phosphate. Clients with heart failure often follow a sodium-restricted diet. Sodium phosphate laxatives can lead to sodium absorption, causing fluid retention, which is contraindicated in heart failure. It is crucial to avoid sodium phosphate laxatives in these clients to prevent exacerbation of fluid overload and heart failure symptoms. Psyllium (choice B), Bisacodyl (choice C), and Polyethylene glycol (choice D) are not contraindicated in clients with heart failure and can be used safely for bowel management.
