1. Which of the following statements is true of sickle-cell anemia?
- A. It is typically managed with treatments such as pain relief medications.
- B. It is caused by a mutation in the beta-globin gene.
- C. It leads to the obstruction of small blood vessels and decreased oxygen delivery.
- D. It is more prevalent in individuals of African, Mediterranean, Middle Eastern, and Indian descent.
Correct answer: C
Rationale: The correct answer is C. Sickle-cell anemia results from a mutation in the beta-globin gene, causing red blood cells to become sickle-shaped. These misshapen cells can obstruct small blood vessels, leading to reduced oxygen delivery to tissues. Choices A, B, and D are incorrect because sickle-cell anemia is typically managed with treatments such as pain relief medications, hydration, and in severe cases, blood transfusions. It is caused by a specific mutation in the beta-globin gene, not by the inability to metabolize phenylalanine. Additionally, sickle-cell anemia is more prevalent in individuals of African, Mediterranean, Middle Eastern, and Indian descent, not exclusive to any specific gender.
2. A client is receiving a blood transfusion. The client reports flank pain, and the nurse notes reddish-brown urine in the client's urinary catheter bag. The nurse recognizes these manifestations as which of the following types of transfusion reactions?
- A. Hemolytic
- B. Allergic
- C. Febrile
- D. Transfusion-related acute lung injury (TRALI)
Correct answer: A
Rationale: The correct answer is A: Hemolytic. Hemolytic reactions can lead to flank pain and hemoglobinuria, as the body breaks down the transfused red blood cells. In hemolytic reactions, the immune system attacks and destroys the transfused red blood cells, causing the release of hemoglobin into the bloodstream and urine. This results in reddish-brown urine, indicating hemoglobinuria. Allergic reactions typically present with symptoms like itching, hives, or rash. Febrile reactions are characterized by fever, chills, and rigors. TRALI is a rare but serious transfusion reaction that manifests as acute respiratory distress following a transfusion, not flank pain and hemoglobinuria.
3. The nurse is preparing to provide a complete bed bath to an unconscious patient. The nurse decides to use a bag bath. In which order will the nurse clean the body, starting with the first area?
- A. Neck, shoulders, and chest
- B. Abdomen and groin/perineum
- C. Legs, feet, and web spaces
- D. Back of neck, back, and then buttocks
Correct answer: B
Rationale: In providing a complete bed bath using a bag bath for an unconscious patient, the nurse should follow a specific order. The correct sequence is as follows: Neck, shoulders, and chest; Both arms, both hands, web spaces, and axilla; Abdomen and then groin/perineum; Right leg, right foot, and web spaces; Left leg, left foot, and web spaces; Back of neck, back, and then buttocks. Choice A is incorrect as it does not follow the correct sequence for a bed bath. Choice C is incorrect as it focuses on the lower extremities before addressing the upper body. Choice D is incorrect as it starts with the back of the patient instead of the upper body areas first.
4. During a neurologic examination, which assessment should a nurse perform to test a client's balance?
- A. Romberg test
- B. Heel-to-toe walk
- C. Snellen test
- D. Spinal accessory function
Correct answer: A
Rationale: The Romberg test is used to assess a client's balance by evaluating their ability to maintain a steady posture with eyes closed. The heel-to-toe walk is another assessment that tests balance by assessing gait and coordination. The Snellen test is used to assess visual acuity and is unrelated to balance. Testing spinal accessory function involves assessing the movement of the head and shoulders and is not directly related to balance assessment.
5. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?
- A. Low oxygen levels are present in the blood.
- B. High levels of carbon dioxide have accumulated in the blood.
- C. Increased bicarbonate levels are causing alkalosis.
- D. Respiratory rate is increased, causing hyperventilation.
Correct answer: B
Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.
