A patient admitted with gastrointestinal tract bleeding has a hemoglobin level of 6 g/dL. She asks the nurse why she feels SOB. Which response is best?
- A. “Anemia prevents your lungs from absorbing oxygen effectively.”
- B. “You do not have enough hemoglobin to carry oxygen to your tissues.”
- C. “”You don’t have enough blood to feed your cells.”
- D. “You have lost a lot of blood, and that has damaged your lungs.”
Correct Answer: B
Rationale: The correct answer is B because hemoglobin carries oxygen to the tissues, and with a low hemoglobin level of 6 g/dL, there is insufficient oxygen-carrying capacity to meet the body's needs, leading to shortness of breath (SOB). Choice A is incorrect as anemia affects oxygen transport, not absorption. Choice C is incorrect as anemia affects oxygen delivery, not nutrient delivery. Choice D is incorrect as the primary reason for SOB in this scenario is the lack of oxygen-carrying capacity due to low hemoglobin levels, not lung damage from blood loss.

The client with trigeminal neuralgia tells the nurse that acetaminophen (Tylenol) is taken daily for the relief of generalized discomfort. Which laboratory value would indicate toxicity associated with the medication?
- A. Sodium level of 140 mEq/l.
- B. Direct bilirubin level of 2 mg/dl
- C. Prothrombin time of 12 seconds
- D. Platelet count of 400,000/mm3
Correct Answer: B
Rationale: The correct answer is B: Direct bilirubin level of 2 mg/dl. Acetaminophen toxicity can lead to liver damage, causing an increase in bilirubin levels. Direct bilirubin specifically indicates liver function. A: Sodium level is not related to acetaminophen toxicity. C: Prothrombin time is a measure of blood clotting, not indicative of acetaminophen toxicity. D: Platelet count is not affected by acetaminophen toxicity.
The nurse is teaching a group of women to perform breast self-examination. The nurse should explain that the purpose of performing the examination is to discover:
- A. Cancerous lumps.
- B. Changes from previous self-examinations.
- C. Areas of thickness or fullness.
- D. Fibrocystic masses.
Correct Answer: A
Rationale: The correct answer is A: Cancerous lumps. Breast self-examination aims to detect any abnormal changes in the breasts, including potential cancerous lumps. Detecting cancerous lumps early increases the chances of successful treatment and improved outcomes. Choices B, C, and D are incorrect because while changes from previous self-examinations, areas of thickness or fullness, and fibrocystic masses can be important to note, the primary goal of breast self-examination is to identify any signs of breast cancer, such as cancerous lumps.
After reviewing the database, the nurse discovers that the patient’s vital signs have not been recorded by the nursing assistive personnel (NAP). Which clinical decision should the nurse make? Administer scheduled medications assuming that the NAP would have reported
- A. abnormal vital signs. Have the patient transported to the radiology department for a scheduled x-ray, and
- B. review vital signs upon return.
- C. Ask the NAP to record the patient’s vital signs before administering medications.
- D. Omit the vital signs because the patient is presently in no distress.
Correct Answer: C
Rationale: Rationale for Choice C:
1. Safety First: Recording vital signs is crucial for patient safety. Asking the NAP to record vital signs ensures the patient's condition is monitored before administering medications.
2. Accountability: Nurses are responsible for ensuring accurate documentation of vital signs. Asking the NAP to record them maintains accountability within the healthcare team.
3. Communication: By requesting the NAP to record vital signs, the nurse fosters effective communication and collaboration in patient care.
Summary of Other Choices:
A: Administering medications without reviewing vital signs could lead to adverse effects if there are abnormalities.
B: Reviewing vital signs upon return delays immediate action and could jeopardize patient safety.
D: Omitting vital signs neglects the essential monitoring required for patient care and could result in missed opportunities for early intervention.
One of the complications of prolonged bed rest is decubitus ulcer. Which of the following can best prevent its occurrence?
- A. Massage reddened areas with lotion or oils
- B. Use special water mattress
- C. Turn frequently every 2 hours
- D. Keep skin clean and dry
Correct Answer: C
Rationale: The correct answer is C: Turn frequently every 2 hours. This helps redistribute pressure, preventing constant pressure on one area and reducing the risk of developing pressure ulcers. Turning every 2 hours promotes circulation and relieves pressure points.
A: Massaging reddened areas can worsen the condition by increasing friction and pressure.
B: While a special water mattress can help in preventing pressure ulcers, turning frequently is more effective.
D: Keeping the skin clean and dry is important for overall skin health but may not directly prevent pressure ulcers.
A clinical nurse specialist (CNS) is orienting a new graduate registered nurse to an oncology unit where blood product transfusions are frequently administered. In discussing ABO compatibility, the CNS presents several hypothetical scenarios. A well-informed new graduate would know the greatest likelihood of an acute hemolytic reaction would occur when giving:
- A. A-positive blood to an A-negative client
- B. O-positive blood to an A-positive client
- C. O-negative blood to an O-positive client
- D. B-positive blood to an AB-positive client
Correct Answer: A
Rationale: The correct answer is A: A-positive blood to an A-negative client. This is because in ABO blood typing, individuals with blood type A have anti-B antibodies in their plasma. Therefore, if A-positive blood (which contains the A antigen) is given to an A-negative client (who has anti-A antibodies), there is a high risk of an acute hemolytic reaction due to the antibodies attacking the transfused blood cells.
Choices B, C, and D are incorrect because they do not involve a mismatch of ABO blood types that would lead to a significant risk of acute hemolytic reaction. In choice B, O-positive blood can be safely transfused to an A-positive client as O blood is considered the universal donor. In choice C, O-negative blood can be safely given to an O-positive client as O-negative blood is compatible with all blood types. In choice D, B-positive blood can be safely administered to an AB-positive client as the AB blood type can receive both
