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.

Which adverse reaction poses the greatest life-threatening risk when taking Omeprazole?
- A. Chest pain
- B. Constipation
- C. Clostridium difficile-associated diarrhea
- D. Acute interstitial nephritis
Correct Answer: C
Rationale: The most life-threatening adverse reaction associated with Omeprazole is Clostridium difficile-associated diarrhea. This condition can be severe and life-threatening due to the potential for dehydration, electrolyte imbalances, and complications such as toxic megacolon. Chest pain, constipation, and acute interstitial nephritis are potential side effects of Omeprazole but are not considered as life-threatening as Clostridium difficile-associated diarrhea. Monitoring for signs of this adverse reaction is crucial, and immediate medical attention should be sought if symptoms develop.
A client has been prescribed Warfarin for atrial fibrillation. Which of the following instructions should the nurse include in the discharge teaching?
- A. Avoid foods high in vitamin K.
- B. Take this medication with food to prevent nausea.
- C. Monitor your heart rate daily before taking the medication.
- D. Limit your fluid intake to 1 liter per day.
Correct Answer: A
Rationale: The correct instruction for the nurse to include in the discharge teaching for a client prescribed Warfarin is to 'Avoid foods high in vitamin K.' Foods high in vitamin K can decrease the effectiveness of Warfarin by interfering with its anticoagulant effects, potentially leading to blood clotting issues. It is crucial for clients on Warfarin therapy to maintain a consistent intake of vitamin K-containing foods to ensure the stability of the medication's effects. Choices B, C, and D are incorrect because taking Warfarin with food, monitoring heart rate daily, or limiting fluid intake are not directly related to optimizing the effectiveness of Warfarin therapy.
A client has a new prescription for Atenolol. Which of the following client statements indicates an understanding of the teaching?
- A. I should monitor my blood pressure regularly.
- B. I will take this medication at bedtime.
- C. I will take this medication with a high-fat meal.
- D. I should increase my intake of potassium-rich foods.
Correct Answer: A
Rationale: The correct answer is A. Clients taking Atenolol, a beta-blocker, should monitor their blood pressure regularly to ensure the medication is effectively managing their condition. Monitoring blood pressure helps in assessing the drug's effectiveness and identifying any potential side effects that may influence blood pressure levels. Choices B, C, and D are incorrect because taking Atenolol at bedtime, with a high-fat meal, or increasing potassium-rich foods intake are not recommended actions associated with this medication and do not demonstrate an understanding of the teaching.
Advil, Motrin, and Nuprin are examples of
- A. chemical names
- B. combination names
- C. trade names
- D. generic names
Correct Answer: C
Rationale: Advil, Motrin, and Nuprin are trade (brand) names for ibuprofen, marketed by different companies, distinct from its generic name (ibuprofen) or chemical name (e.g., 2-(4-isobutylphenyl)propanoic acid). Combination names aren't a category. Trade names reflect commercial branding, familiar to clients, a key distinction in pharmacology.
A solution for the eyes
- A. effervescent
- B. mucilage
- C. spirits
- D. collyria
Correct Answer: D
Rationale: Collyria refers to eye drops or an eye lotion that is used to treat eye conditions. When the question is asking for a solution for the eyes, collyria is the most appropriate choice among the options given. Effervescent, mucilage, and spirits do not specifically relate to eye treatments. Collodion is a type of liquid adhesive used in medical settings, but it is not primarily intended for eye-related issues. Therefore, collyria is the correct solution for the eyes.
