Nursing Elites

1. A client with tuberculosis is starting medication therapy with isoniazid, rifampin, and pyrazinamide. Which of the following instructions should the nurse include?

• A. Take isoniazid with an antacid.
• B. Provide a sputum specimen every 2 weeks to the clinic for testing.
• C. Expect your sputum cultures to be negative after 6 months of therapy.
• D. Drink at least 8 ounces of water when you take the pyrazinamide tablet.

Correct answer: D

Rationale: Pyrazinamide can cause gastrointestinal upset and is best taken with a full glass of water to minimize irritation to the stomach lining. This instruction helps reduce the risk of adverse effects associated with pyrazinamide. Options A and C are not directly related to the medication regimen for tuberculosis. While sputum testing is important, the frequency mentioned in option B is not required every two weeks.

2. How does the pain of a myocardial infarction (MI) differ from stable angina?

• A. Accompanied by shortness of breath
• B. Feelings of fear or anxiety
• C. Lasts less than 15 minutes
• D. No relief from taking nitroglycerin

Correct answer: C

Rationale: The pain of a myocardial infarction (MI) is often accompanied by shortness of breath and feelings of fear or anxiety. Unlike stable angina, the pain of an MI typically lasts longer than 15 minutes and is not relieved by nitroglycerin. Additionally, it can occur without a known cause, unlike stable angina which often has a trigger such as exertion.

3. A healthcare professional is assessing a client who has a fracture of the femur. Vital signs are obtained on admission and again in 2 hours. Which of the following changes in assessment should indicate to the healthcare professional that the client could be developing a serious complication?

• A. Increased respiratory rate from 18 to 44/min
• B. Increased oral temperature from 36.6� C (97.8� F) to 37� C (98.6� F)
• C. Increased blood pressure from 112/68 to 120/72 mm Hg
• D. Increased heart rate from 68 to 72/min

Correct answer: A

Rationale: An increased respiratory rate from 18 to 44/min is a significant change that should alert the healthcare professional to a potential serious complication. Such a drastic increase in respiratory rate may indicate respiratory distress or hypoxia, which are critical conditions requiring immediate attention. The other options show minor changes in vital signs that are within normal limits and are less likely to indicate a serious complication.

4. A client is on intravenous heparin to treat a pulmonary embolism. The client's most recent partial thromboplastin time (PTT) was 25 seconds. What action should the nurse anticipate?

• A. Decrease the heparin rate.
• B. Increase the heparin rate.
• C. No change to the heparin rate.
• D. Stop the heparin; start warfarin (Coumadin).

Correct answer: B

Rationale: For clients on heparin therapy, a PTT value of 1.5 to 2.5 times the normal range is required to ensure therapeutic anticoagulation. The normal PTT range is 25 to 35 seconds. In this case, the client's PTT of 25 seconds falls below the therapeutic range, indicating that the heparin dose is insufficient. Therefore, the nurse should anticipate increasing the heparin rate to achieve the desired therapeutic effect.

5. A client is postoperative with shallow respirations at 9/min. Which acid-base imbalance should the nurse identify the client as being at risk for developing initially?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: A

Rationale: The client's shallow respirations at 9/min indicate hypoventilation, leading to an accumulation of carbon dioxide in the blood, causing respiratory acidosis. In this scenario, the client is at risk for developing respiratory acidosis due to inadequate ventilation and subsequent CO2 retention.
