1. A client is starting a course of Metronidazole to treat an infection. For which of the following adverse effects should the client stop taking Metronidazole and notify the provider?
- A. Metallic taste
- B. Nausea
- C. Ataxia
- D. Dark-colored urine
Correct answer: C
Rationale: The correct answer is C, 'Ataxia.' Ataxia is a sign of central nervous system (CNS) toxicity, which can be a severe adverse effect of Metronidazole. Metallic taste and nausea are common side effects of Metronidazole but do not require stopping the medication unless they persist or worsen. Dark-colored urine is not typically associated with Metronidazole and does not indicate a severe adverse effect.
2. 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.
3. A healthcare professional is preparing to administer Enoxaparin to a client. Which of the following actions should the healthcare professional take?
- A. Administer the medication orally.
- B. Massage the injection site after administration.
- C. Insert the needle at a 45- to 90-degree angle.
- D. Aspirate before injecting the medication.
Correct answer: C
Rationale: Enoxaparin should be administered subcutaneously at a 45- to 90-degree angle. This angle ensures proper delivery of the medication. Massaging the injection site should be avoided to prevent bruising and possible tissue damage. Aspiration is not required for subcutaneous injections like Enoxaparin. Therefore, the correct action for administering Enoxaparin is to insert the needle at a 45- to 90-degree angle.
4. When educating a client with a new prescription for albuterol, which instruction should the nurse include?
- A. Use the inhaler every 4 hours.
- B. Shake the inhaler before use.
- C. Take a deep breath before inhaling the medication.
- D. Use a spacer when using the inhaler.
Correct answer: B
Rationale: Shaking the albuterol inhaler before use is essential to ensure that the medication is evenly mixed and properly delivered when inhaled. This maximizes the effectiveness of the medication in opening the airways and relieving symptoms of bronchospasm.
5. A client has a new prescription for a Nitroglycerin transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch to the same site each day.
- B. Remove the patch at night.
- C. Cover the patch with a heating pad.
- D. Apply the patch to a hairless area of skin.
Correct answer: D
Rationale: The correct instruction is to apply the Nitroglycerin transdermal patch to a hairless area of skin. This ensures proper absorption of the medication. It is important to rotate the application site daily to prevent skin irritation and tolerance development. Applying the patch to the same site each day can lead to decreased efficacy and potential skin reactions. Removing the patch at night is not necessary as the patches are usually worn continuously to provide constant medication delivery. Covering the patch with a heating pad can increase the absorption of the medication and lead to an overdose, which is not recommended.
