1. What is the therapeutic use of metformin?

• A. Lower blood pressure
• B. Diminish seizure activity
• C. The maintenance of a person's blood glucose levels
• D. Increase heart rate and decrease gastrointestinal secretions

Correct answer: C

Rationale: Metformin is commonly prescribed to manage and control blood glucose levels in individuals with diabetes. It helps in reducing the amount of glucose produced by the liver and improves the body's response to insulin, thereby aiding in the regulation of blood sugar levels. It is not used to lower blood pressure, diminish seizure activity, increase heart rate, or decrease gastrointestinal secretions.

2. What is the appropriate medication to administer for a suspected opioid overdose in a patient who comes to the hospital?

• A. Exenatide
• B. Naloxone
• C. Heparin
• D. Tolvaptan

Correct answer: B

Rationale: The correct answer is B: Naloxone. Naloxone is the drug of choice for managing opioid overdoses as it competitively antagonizes opioid receptors, reversing the respiratory depression and sedation caused by opioids. It is crucial in the emergency treatment of opioid overdose to prevent fatal outcomes. Choices A, C, and D are incorrect. Exenatide is a medication used to treat diabetes, heparin is an anticoagulant, and tolvaptan is a diuretic. None of these medications are indicated for the management of opioid overdose.

3. A client with chronic kidney disease has a new prescription for epoetin alfa. The nurse should instruct the client to increase dietary intake of which of the following substances?

• A. Iron
• B. Protein
• C. Potassium
• D. Sodium

Correct answer: A

Rationale: Patients with chronic kidney disease are often prescribed epoetin alfa to treat anemia. Epoetin alfa stimulates red blood cell production, increasing the body's demand for iron to support this process. Therefore, clients taking epoetin alfa should be advised to increase their dietary intake of iron-rich foods to meet the increased demand and prevent iron deficiency anemia. Choices B, C, and D are incorrect because while protein is essential for overall health, potassium and sodium intake may need to be restricted in clients with chronic kidney disease to manage electrolyte balance and blood pressure.

4. A healthcare professional is caring for a client who is prescribed Metformin. Which of the following laboratory values should the healthcare professional monitor to assess for potential adverse effects?

• A. Blood glucose
• B. Creatine kinase
• C. Hemoglobin A1c
• D. Serum creatinine

Correct answer: D

Rationale: Corrected Rationale: Metformin can lead to lactic acidosis, especially in individuals with impaired renal function. Monitoring the client's serum creatinine levels is crucial to assess kidney function because Metformin is eliminated by the kidneys, and impaired renal function can increase the risk of adverse effects. Monitoring blood glucose levels is essential for assessing the effectiveness of Metformin in managing diabetes but is not directly related to potential adverse effects of Metformin. Creatine kinase is not typically monitored in relation to Metformin therapy. Hemoglobin A1c is used to assess long-term glucose control in diabetes but is not specific for monitoring Metformin adverse effects.

5. 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.
