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. The client asks the nurse about common side effects of calcium channel blockers. What should the nurse include in client teaching?

• A. Headache
• B. Constipation
• C. Epistaxis
• D. Dysuria

Correct answer: A

Rationale: One of the common side effects of calcium channel blockers is a headache. This is important information for the nurse to include in client teaching as it helps the client understand potential adverse effects of the medication. Constipation, epistaxis, and dysuria are not typically associated with calcium channel blockers.

3. When a client is starting long-term oral prednisone for chronic asthma, what adverse effect should the nurse instruct the client to monitor for?

• A. Weight gain
• B. Nervousness
• C. Bradycardia
• D. Constipation

Correct answer: A

Rationale: Weight gain is a common adverse effect of oral prednisone due to sodium and water retention, which can lead to fluid retention. Monitoring weight changes is important as it helps in early identification of this adverse effect, enabling timely interventions to manage it. Choice B, nervousness, is not typically associated with oral prednisone use. Bradycardia (Choice C) is unlikely as prednisone usually causes tachycardia or increased heart rate. Constipation (Choice D) is not a common adverse effect of prednisone compared to weight gain.

4. A patient is receiving IV heparin for a deep-vein thrombosis and begins vomiting blood. After the heparin has been stopped, which of the following medications should the nurse prepare to administer?

• A. Vitamin K1
• B. Atropine
• C. Protamine
• D. Calcium gluconate

Correct answer: C

Rationale: Protamine is the antidote for heparin, as it reverses its anticoagulant effects. In cases of heparin overdose or if there is excessive bleeding, administering protamine can quickly neutralize the effects of heparin, helping to prevent further bleeding complications.

5. A healthcare professional working in an emergency department is caring for a client who has Benzodiazepine toxicity due to an overdose. Which of the following actions is the healthcare professional's priority?

• A. Administer flumazenil.
• B. Identify the client's level of orientation.
• C. Infuse IV fluids.
• D. Prepare the client for gastric lavage.

Correct answer: B

Rationale: When managing a client with Benzodiazepine toxicity, the priority action for the healthcare professional is to assess the client. Identifying the client's level of orientation allows the healthcare professional to understand the client's cognitive status, which is crucial for further interventions and decision-making in the care plan. Administering flumazenil (Choice A) may precipitate withdrawal symptoms and should be done cautiously. Infusing IV fluids (Choice C) can be important but is not the priority over assessing the client. Gastric lavage (Choice D) is not typically recommended due to the risk of complications and its limited effectiveness in cases of Benzodiazepine overdose.
