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 starting a new prescription for furosemide. Which of the following instructions should the nurse include?

• A. Take the medication with food.
• B. Weigh yourself daily.
• C. Take potassium supplements as needed.
• D. Decrease intake of foods high in sodium.

Correct answer: B

Rationale: When a client is prescribed furosemide, it is important to monitor for fluid loss. Weighing oneself daily helps track changes in weight due to fluid loss, which can indicate the effectiveness of the medication. This monitoring assists in managing fluid balance and adjusting the dosage if necessary to achieve the desired therapeutic effect. Choice A is incorrect because furosemide is usually recommended to be taken on an empty stomach. Choice C is incorrect because potassium supplements should only be taken if prescribed by a healthcare provider due to the risk of hyperkalemia with furosemide. Choice D is incorrect because decreasing sodium intake is generally a good dietary practice but not a specific instruction related to furosemide therapy.

3. A client has a new prescription for Simvastatin. Which of the following client statements indicates an understanding of the teaching?

• A. I will take this medication at bedtime.
• B. I should avoid eating grapefruit while taking this medication.
• C. I will need to monitor my blood sugar closely while taking this medication.
• D. I will stop taking the medication if I develop muscle pain.

Correct answer: B

Rationale: The correct answer is B. Grapefruit can increase the levels of simvastatin in the blood, leading to an increased risk of serious side effects, including muscle pain or damage. Therefore, it is crucial for the client to avoid consuming grapefruit while taking this medication to prevent potential complications.

4. A preschooler weighing 44 lb is to receive Amoxicillin 20 mg/kg/day PO divided equally every 12 hr. The available amoxicillin suspension is 250 mg/5 mL. How many mL should the nurse administer per dose?

• A. 4 mL
• B. 5 mL
• C. 6 mL
• D. 3 mL

Correct answer: A

Rationale: To calculate the dosage per administration: First, convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, calculate the required dosage per dose: (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. To determine the mL per dose, divide the required dosage by the concentration of the amoxicillin suspension: (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the correct answer is 4 mL. Choice B (5 mL) is incorrect because the correct calculation yields 4 mL. Choices C (6 mL) and D (3 mL) are also incorrect as they do not align with the accurate calculation based on the provided information.

5. A client in labor is receiving IV Opioid analgesics. Which of the following actions should the nurse take?

• A. Instruct the client to self-ambulate every 2 hours.
• B. Offer oral hygiene every 2 hours.
• C. Anticipate medication administration 2 hours prior to delivery.
• D. Monitor fetal heart rate every 2 hours.

Correct answer: B

Rationale: Offering oral hygiene every 2 hours is essential for a client receiving opioid analgesics to prevent dry mouth, nausea, and vomiting, which are common adverse effects associated with opioid use. This intervention promotes comfort and enhances the client's well-being during labor. Instructing the client to self-ambulate every 2 hours is not appropriate for a client in labor receiving opioid analgesics, as it may be challenging and unnecessary during this time. Anticipating medication administration 2 hours prior to delivery is not necessary as the timing of medication administration should be based on the client's pain level and the duration of action of the opioid. Monitoring fetal heart rate every 2 hours is important during labor, but the priority in this case is to address the client's comfort and well-being by offering oral hygiene.
