Nursing Elites

1. A client has a new diagnosis of tuberculosis and has been placed on a multi-medication regimen. Which of the following instructions should the nurse give the client related to ethambutol?

• A. Your urine can turn a dark orange.
• B. Watch for a change in the sclera of your eyes.
• C. Watch for any changes in vision.
• D. Take vitamin B6 daily.

Correct answer: C

Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.

2. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

3. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:

• A. Infection
• B. Hypothermia
• C. Anxiety
• D. Dehydration

Correct answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

4. The healthcare professional is preparing to take vital signs in an alert client admitted to the hospital with dehydration secondary to vomiting and diarrhea. What is the best method used to assess the client’s temperature?

• A. Oral
• B. Axillary
• C. Radial
• D. Heat-sensitive tape

Correct answer: A

Rationale: The most accurate method for assessing temperature in an alert client is the oral method. It provides a more reliable reflection of the body's core temperature compared to axillary or radial methods. In cases of dehydration, it is important to get an accurate temperature reading to monitor the client's condition closely. Axillary temperature may be affected by environmental factors, while radial temperature measurement is not a standard method for assessing core body temperature. Heat-sensitive tape is not a recognized method for assessing body temperature in clinical practice.

5. A client is being cared for by a nurse 2 hours after admission. The client has an SaO2 of 91%, exhibits audible wheezes, and is using accessory muscles when breathing. Which of the following classes of medication should the nurse expect to administer?

• A. Antibiotic
• B. Beta-blocker
• C. Antiviral
• D. Beta2 agonist

Correct answer: D

Rationale: The client's presentation with an SaO2 of 91%, audible wheezes, and use of accessory muscles indicates respiratory distress, likely due to bronchoconstriction. Beta2 agonists are the appropriate class of medications to administer in this situation as they act as bronchodilators, helping to relieve the bronchoconstriction and improve airflow to the lungs. Antibiotics, beta-blockers, and antivirals are not indicated for this client's respiratory distress symptoms.
