1. 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).

2. 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.

3. What should be done in order to prevent contamination of the environment when making a bed?

• A. Avoid flinging soiled linens
• B. Strip all linens at the same time
• C. Finish both sides at the same time
• D. Embrace soiled linen

Correct answer: A

Rationale: The correct practice to prevent contamination of the environment when making a bed is to avoid flinging soiled linens. Flinging soiled linens can spread contaminants in the environment, leading to potential health risks. By handling soiled linens properly and avoiding flinging them, the risk of contamination is minimized, ensuring a safer and cleaner environment. Stripping all linens at the same time (choice B) may not necessarily prevent contamination if the soiled linens are flung around. Finishing both sides at the same time (choice C) is unrelated to preventing contamination. Embracing soiled linen (choice D) is not hygienic and can lead to spreading contaminants.

4. Prior to a thoracentesis, which of the following actions should the nurse take?

• A. Position the client in an upright position, leaning over the bedside table.
• B. Explain the procedure.
• C. Obtain ABGs.
• D. Administer benzocaine spray.

Correct answer: A

Rationale: Positioning the client in an upright position, leaning over the bedside table helps to facilitate access to the thoracic cavity during the thoracentesis procedure. This position allows for easier identification and access to the insertion site. Explaining the procedure to the client is important, but positioning is the priority. Obtaining ABGs is not directly related to the thoracentesis procedure. Administering benzocaine spray is not a standard practice before a thoracentesis.

5. During the assessment of a client receiving packed RBCs, which finding indicates fluid overload?

• A. Low back pain.
• B. Dyspnea.
• C. Hypotension.
• D. Thready pulse.

Correct answer: B

Rationale: Dyspnea is a key finding indicating fluid overload in a client receiving packed RBCs. Fluid overload can lead to pulmonary edema, causing difficulty breathing or shortness of breath (dyspnea). Low back pain is not typically associated with fluid overload but can be more related to musculoskeletal issues. Hypotension and thready pulse are more indicative of hypovolemia (low fluid volume), not fluid overload.
