Nursing Elites

1. A nurse reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the nurse take?

• A. Obtain a blood specimen immediately prior to administering the next dose of medication.
• B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
• C. Ask the client to provide a urine specimen after the next dose of medication.
• D. Administer the medication and obtain a blood specimen 30 minutes later.

Correct answer: A

Rationale: To verify the trough levels of a medication accurately, the nurse should obtain a blood specimen immediately before administering the next dose of the medication. The trough level represents the lowest concentration of the medication in the bloodstream, typically right before the next dose is due. This timing ensures an accurate assessment of the drug's concentration in the body at its lowest point, aiding in determining the drug's effectiveness and potential toxicity levels. Choice B is incorrect because waiting for 24 hours would not provide the trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect as obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level.

2. A client in an acute care facility is receiving IV Nitroprusside for hypertensive crisis. The nurse should monitor the client for which of the following adverse reactions to this medication?

• A. Intestinal ileus
• B. Neutropenia
• C. Delirium
• D. Hyperthermia

Correct answer: C

Rationale: The correct answer is C: Delirium. When IV nitroprusside is administered at high dosages, it can lead to thiocyanate toxicity, resulting in mental status changes such as delirium. Monitoring thiocyanate levels during therapy is crucial to ensure they remain below 10 mg/dL to prevent this adverse reaction. Choices A, B, and D are incorrect because nitroprusside does not typically cause intestinal ileus, neutropenia, or hyperthermia as adverse reactions.

3. To which pharmacologic classification does the drug propranolol belong?

• A. Beta Blockers
• B. Cholinergics
• C. Immune globulins
• D. Barbiturates

Correct answer: A

Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.

4. A healthcare professional is preparing to administer Filgrastim for the first time to a client who has just undergone a bone marrow transplant. Which of the following interventions is appropriate?

• A. Administer intravenously to prevent injury.
• B. Ensure that the medication is kept refrigerated until just prior to administration.
• C. Do not shake the vial; gently invert it to mix before withdrawing the dose.
• D. Discard the vial after removing one dose of the medication.

Correct answer: D

Rationale: When administering Filgrastim, only one dose should be withdrawn from the vial, and the vial should then be discarded to prevent any contamination or errors in dosing. It is crucial not to shake the vial but gently invert it to mix the medication before withdrawing the appropriate dose. Refrigeration is not required for Filgrastim; it should be stored at room temperature until just before administration. Choice A is incorrect because Filgrastim is typically administered subcutaneously, not intravenously. Choice B is incorrect as the medication should be stored at room temperature, not refrigerated, until administration. Choice C is incorrect as shaking the vial is not recommended for Filgrastim.

5. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.
