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 Calcitonin-salmon for Osteoporosis. Which of the following tests should the nurse tell the client to expect before beginning this medication?

• A. Skin test for allergy to the medication
• B. ECG to rule out cardiac dysrhythmias
• C. Mantoux test to rule out exposure to tuberculosis
• D. Liver function tests to assess risk for medication toxicity

Correct answer: A

Rationale: Before starting Calcitonin-salmon, it is important to assess for any potential allergies as anaphylaxis can occur. A skin test is usually conducted to determine if the client is allergic to the medication. The nurse should also inquire about any previous allergies to fish, as Calcitonin-salmon is derived from salmon. Options B, C, and D are not necessary before initiating Calcitonin-salmon therapy. ECG is not directly related to this medication, Mantoux test is used to diagnose tuberculosis, and liver function tests are not specifically required before starting Calcitonin-salmon.

3. A client taking nitroglycerin (Nitrostat) for angina asks the nurse to explain possible side effects. What should NOT be included in client teaching?

• A. Reflex tachycardia
• B. Dizziness
• C. Hyponatremia
• D. Hypotension

Correct answer: C

Rationale: Hyponatremia is not a common side effect associated with nitroglycerin use. Nitroglycerin typically causes side effects such as reflex tachycardia, dizziness, and hypotension due to its vasodilatory effects. Therefore, it is important for the nurse to educate the client about these potential side effects to promote understanding and appropriate management.

4. A healthcare professional is preparing to administer morphine 4 mg IV to a client. Available is morphine 10 mg/mL. How many mL should the healthcare professional administer?

• A. 0.2 mL
• B. 0.4 mL
• C. 0.6 mL
• D. 0.8 mL

Correct answer: B

Rationale: To administer 4 mg from a solution of 10 mg/mL, the healthcare professional should administer 0.4 mL. The calculation is done by dividing the desired dose (4 mg) by the concentration of the solution (10 mg/mL), which equals 0.4 mL. Choice A (0.2 mL) is incorrect because it is half of the correct calculation. Choice C (0.6 mL) is incorrect because it is 50% more than the correct calculation. Choice D (0.8 mL) is incorrect because it exceeds the correct calculation.

5. A client has a new prescription for clonidine to treat hypertension. Which of the following instructions should the nurse include?

• A. Discontinue the medication if a rash develops.
• B. Expect increased salivation during the first few weeks of therapy.
• C. Avoid driving until the client's reaction to the medication is known.
• D. Stop the medication if you experience a dry mouth.

Correct answer: C

Rationale: The correct instruction for a client starting clonidine therapy for hypertension is to avoid driving until their reaction to the medication is known. Clonidine can cause drowsiness, so it is important for the client to refrain from activities that require alertness until they are aware of how the medication affects them. Choice A is incorrect because a rash is not a common side effect of clonidine. Choice B is incorrect as increased salivation is not an expected side effect of clonidine. Choice D is also incorrect as dry mouth is a common side effect of clonidine, but it is not a reason to stop the medication unless severe or bothersome. Therefore, the priority instruction for the nurse to include is to advise the client to avoid driving until their reaction to the medication is known to ensure safety.
