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 Morphine to manage post-operative pain. Which of the following assessments should the nurse perform first?

• A. Urine output
• B. Bowel sounds
• C. Pain level
• D. Respiratory rate

Correct answer: D

Rationale: The nurse should prioritize assessing the client's respiratory rate first when administering Morphine due to the risk of respiratory depression, which is a life-threatening adverse effect of this medication. Monitoring the respiratory rate is crucial to detect any signs of respiratory distress early and take prompt action to ensure the client's safety. Assessing urine output, bowel sounds, and pain level are also important but not as critical as monitoring respiratory rate when initiating Morphine therapy.

3. A client has a new prescription for Phenytoin. Which of the following instructions should the nurse include?

• A. Brush and floss your teeth regularly.
• B. Avoid drinking grapefruit juice.
• C. Take this medication with food.
• D. Increase your intake of calcium-rich foods.

Correct answer: A

Rationale: The correct answer is to instruct the client to brush and floss their teeth regularly. Phenytoin can lead to gingival hyperplasia, making oral hygiene crucial to prevent complications. Encouraging good oral care practices helps reduce the risk of adverse effects on the gums and teeth. Avoiding grapefruit juice is not specifically related to Phenytoin. While some medications require intake with food, Phenytoin is usually taken on an empty stomach for better absorption. Increasing calcium-rich foods is not directly associated with Phenytoin therapy.

4. What is the pharmacological class of Lithium?

• A. Antidiabetics, biguanides
• B. Mood stabilizers
• C. Antiarrhythmics, anticonvulsants
• D. Vascular headache suppressants

Correct answer: B

Rationale: Lithium is classified as a mood stabilizer due to its primary use in managing bipolar disorder, where it helps stabilize mood swings and prevent episodes of mania and depression. While it can have other effects on the body, its main therapeutic role lies in its mood-stabilizing properties. Choices A, C, and D are incorrect as lithium is not classified as antidiabetics, biguanides, antiarrhythmics, anticonvulsants, or vascular headache suppressants. Its main pharmacological class is mood stabilizers.

5. A healthcare professional is planning to administer IV Alteplase to a client who is demonstrating manifestations of a massive Pulmonary Embolism. Which of the following interventions should the healthcare professional plan to take?

• A. Administer IM Enoxaparin along with the Alteplase dose.
• B. Hold direct pressure on puncture sites for up to 30 min.
• C. Administer Aminocaproic acid IV prior to alteplase infusion.
• D. Prepare to administer Alteplase within 8 hr of manifestation onset.

Correct answer: B

Rationale: The correct intervention when administering IV Alteplase is to hold direct pressure on puncture sites for 10 to 30 minutes or until oozing of blood stops. This helps prevent bleeding complications associated with thrombolytic therapy. Administering IM Enoxaparin is not indicated with Alteplase, as it is an anticoagulant rather than a thrombolytic agent. Aminocaproic acid is not typically administered prior to alteplase infusion in the context of a massive Pulmonary Embolism. While timely administration of Alteplase is important, the specific timeframe within which it should be administered may vary based on the clinical situation, so a strict 8-hour window is not universally applicable.
