1. When caring for a client prescribed warfarin, which laboratory test should the nurse monitor to evaluate the therapeutic effect of the medication?

• A. aPTT
• B. Platelet count
• C. BUN
• D. PT/INR

Correct answer: D

Rationale: The correct laboratory test to monitor the therapeutic effect of warfarin is the PT/INR. Warfarin affects blood clotting, and the PT/INR levels indicate the effectiveness of the medication in preventing clot formation. Therefore, monitoring PT/INR levels helps ensure that the client is within the therapeutic range and is protected from potential complications related to clotting. Choice A (aPTT) is incorrect because while it measures the clotting time, it is not the preferred test for monitoring warfarin therapy. Choice B (Platelet count) is incorrect as it assesses the number of platelets and not the medication's therapeutic effect. Choice C (BUN) is unrelated to monitoring the effects of warfarin therapy and is primarily used to assess kidney function.

2. A client has been taking Phenylephrine nasal drops for the past 10 days for Sinusitis. The nurse should assess the client for which of the following adverse effects of this medication?

• A. Sedation
• B. Nasal congestion
• C. Productive cough
• D. Constipation

Correct answer: B

Rationale: The correct answer is B: Nasal congestion. After more than 5 days of use, nasal sympathomimetic medications like phenylephrine can lead to rebound nasal congestion. This occurs due to prolonged vasoconstriction of nasal blood vessels, causing worsening nasal congestion. Sedation (choice A) is not a common adverse effect of phenylephrine nasal drops. Productive cough (choice C) and constipation (choice D) are also not typical adverse effects associated with this medication.

3. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?

• A. Taking four medications decreases the risk of a severe allergic reaction.
• B. Taking four medications reduces the chance that the bacteria will become resistant.
• C. Taking four medications reduces the risk of adverse reactions.
• D. Taking four medications decreases the chance of having a positive tuberculin skin test.

Correct answer: B

Rationale: When treating tuberculosis, using a combination of multiple medications is crucial to reduce the risk of bacterial resistance. The use of four medications helps to target the bacteria from different angles, making it harder for them to develop resistance to the treatment. This approach is essential to ensure the effectiveness of the treatment regimen and to prevent the spread of drug-resistant strains of tuberculosis. Choices A, C, and D are incorrect because the primary reason for using multiple medications in tuberculosis treatment is to prevent the development of bacterial resistance, not to decrease the risk of allergic reactions, adverse reactions, or affecting the tuberculin skin test results.

4. When administering IV Amphotericin B to a client with a systemic fungal infection, the nurse should monitor the client for which of the following adverse effects of this medication?

• A. Hypoglycemia
• B. Constipation
• C. Fever
• D. Hyperkalemia

Correct answer: C

Rationale: The correct answer is fever. Amphotericin B is known to cause adverse effects such as fever, chills, and nausea during infusion. Monitoring for fever is essential as it can indicate an adverse reaction. To manage these effects, pretreatment with diphenhydramine and acetaminophen can be administered.

5. 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 infused at high dosages, it can lead to thiocyanate toxicity, causing mental status changes such as delirium. It is crucial to monitor the thiocyanate levels to ensure they remain below 10 mg/dL during therapy to prevent adverse effects. Choices A, B, and D are incorrect because IV Nitroprusside is not commonly associated with intestinal ileus, neutropenia, or hyperthermia. Monitoring for delirium is crucial due to the risk of thiocyanate toxicity.
