The nurse is caring for a client with acquired immunodeficiency syndrome (AIDS). To adhere to standard precautions, the nurse should:
- A. Maintain strict isolation
- B. Wear gloves when providing mouth care
- C. Keep the client in a private room, if
- D. Wear a gown when delivering the client’s possible food tray
Correct Answer: B
Rationale: The correct answer is B: Wear gloves when providing mouth care. This is because standard precautions for AIDS include wearing gloves when in contact with bodily fluids, such as saliva during mouth care. Maintaining strict isolation (A) is not necessary as AIDS is not transmitted through casual contact. Keeping the client in a private room (C) is not required unless the client has an airborne infection. Wearing a gown when delivering food tray (D) is not necessary for standard precautions unless there is a risk of contamination with bodily fluids.

Why does the nurse instruct the client to avoid Valsalva maneuvers?
- A. Clients BP will decrease momentarily
- B. Client may lose consciousness
- C. Client may suffer from a myocardial
- D. Clients BP will increase momentarily infarction
Correct Answer: B
Rationale: The correct answer is B because performing Valsalva maneuver can lead to a sudden drop in blood pressure, causing the client to lose consciousness. This occurs due to the increased intra-abdominal pressure leading to decreased venous return to the heart. Choices A, C, and D are incorrect as they do not accurately reflect the consequences of Valsalva maneuver. Option A stating that the client's blood pressure will decrease momentarily is incorrect as it actually increases initially. Option C suggesting that the client may suffer from a myocardial infarction is incorrect as Valsalva maneuver does not directly cause heart attacks. Option D implying that the client's blood pressure will increase momentarily is also incorrect as the immediate effect is a rise followed by a significant drop.
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
A client receiving external radiation to the left thorax to treat lung cancer has a nursing diagnosis of Risk for impaired skin integrity. Which intervention should be part of this client’s plan of care?
- A. Avoiding using a soap on the irradiated areas
- B. Applying talcum powder to the irradiated areas daily after bathing
- C. Wearing a lead apron during direct contact with the client
- D. Removing thoracic skin markings after each radiation treatment
Correct Answer: A
Rationale: The correct answer is A: Avoiding using soap on the irradiated areas. This is because soap can irritate the skin, leading to skin breakdown in a client at risk for impaired skin integrity due to radiation therapy. Avoiding soap helps to prevent further damage to the skin.
Choice B is incorrect as talcum powder can further irritate the skin and should be avoided. Choice C is not relevant to preventing skin integrity issues. Choice D is incorrect because thoracic skin markings should not be removed as they are essential for accurate radiation delivery.
The most effective pharmacologic agent for the treatment of Parkinson’s disease is:
- A. Levodopa
- B. Selegilene
- C. Permax
- D. Symmetrel
Correct Answer: A
Rationale: The correct answer is A: Levodopa. Levodopa is the most effective pharmacologic agent for treating Parkinson's disease because it is converted to dopamine in the brain, replenishing the deficient dopamine levels in Parkinson's patients. Selegiline and Symmetrel are also used in treating Parkinson's, but they are typically used as adjunctive therapy rather than the primary treatment. Permax has been withdrawn from the market due to safety concerns, making it an incorrect choice.
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.
