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. During discharge teaching, a client informs the nurse about a new prescription for prednisone for asthma. Which of the following client statements indicates an understanding in teaching?

• A. I will decrease my fluid intake while taking this medication.
• B. I will expect to have black, tarry stools.
• C. I will take my medication with meals.
• D. I will monitor for weight loss while on this medication.

Correct answer: C

Rationale: Taking prednisone with meals can help reduce the risk of gastrointestinal upset and irritation. It is important for the client to understand how to take the medication correctly to maximize its effectiveness and minimize potential side effects. Monitoring for weight loss or changes in stools may be important but does not directly relate to the administration of the medication with meals.

3. Which of the following patients is at greater risk for contracting an infection?

• A. A patient with leukopenia
• B. A patient receiving broad-spectrum antibiotics
• C. A postoperative patient who has undergone orthopedic surgery
• D. A newly diagnosed diabetic patient

Correct answer: A

Rationale: Leukopenia, characterized by low white blood cell count, significantly reduces the body's ability to fight infections. Patients with leukopenia are at a higher risk of contracting infections due to compromised immune defenses.

4. When discussing hair loss with Mrs. Lim, who begins to cry, the best response would be:

• A. Don’t worry. It’s only temporary
• B. Why are you crying? I didn’t get to the bad news yet
• C. Your hair is really pretty
• D. I know this will be difficult for you, but your hair will grow back after the completion of chemotherapy

Correct answer: D

Rationale: When a patient is emotionally affected, it is essential to acknowledge their feelings while providing reassurance and information. Option D demonstrates empathy by acknowledging the difficulty Mrs. Lim is facing and offers hope by reassuring her that her hair will grow back after chemotherapy, which can provide comfort and support during a challenging time.

5. After 1 week of hospitalization, Mr. Gray develops hypokalemia. Which of the following is the most significant symptom of his disorder?

• A. Lethargy
• B. Increased pulse rate and blood pressure
• C. Muscle weakness
• D. Muscle irritability

Correct answer: C

Rationale: Muscle weakness is a hallmark symptom of hypokalemia. Hypokalemia refers to low levels of potassium in the blood, which can affect muscle function. The decreased potassium levels can lead to muscle weakness, cramping, and even paralysis. These symptoms can impact various muscle groups in the body, making muscle weakness the most significant symptom to monitor and address in patients with hypokalemia.
