NCLEX RN Exam Review Answers
1. A client who has undergone radiation therapy presents with itching, redness, burning pain, and skin sloughing on the chest and abdomen. Which nursing intervention is most appropriate for this client?
- A. Apply ointment to the skin to avoid moisture
- B. Wash the area gently with water and pat dry
- C. Use a mild antiseptic soap to wash the area and pat dry
- D. Apply talcum powder to keep the skin dry
Correct answer: B
Rationale: For a client experiencing skin symptoms like redness, itching, burning pain, and sloughing after radiation therapy, it is crucial to maintain proper skin care. Applying ointments, lotions, or powders can worsen the condition by trapping moisture and leading to further skin irritation. The most appropriate intervention is to wash the affected area gently with water to cleanse it without further irritating the skin. Using mild antiseptic soap or talcum powder can also be harsh on the compromised skin. Patting the skin dry helps prevent friction and trauma to the affected area, promoting healing and comfort.
2. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?
- A. Administer bicarbonate.
- B. Complete a head-to-toe assessment.
- C. Place the patient on high-flow oxygen.
- D. Obtain repeat arterial blood gases (ABGs).
Correct answer: C
Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.
3. A patient with leukemia is receiving chemotherapy that is known to depress bone marrow. A CBC (complete blood count) reveals a platelet count of 25,000/microliter. Which of the following actions related specifically to the platelet count should be included in the nursing care plan?
- A. Monitor for fever every 4 hours.
- B. Require visitors to wear respiratory masks and protective clothing.
- C. Consider transfusion of packed red blood cells.
- D. Check for signs of bleeding, including examination of urine and stool for blood.
Correct answer: D
Rationale: A platelet count of 25,000/microliter indicates severe thrombocytopenia, which increases the risk of bleeding. It is crucial to initiate bleeding precautions, including regularly checking for signs of bleeding such as examining urine and stool for blood. Monitoring for fever every 4 hours (Choice A) should be included for neutropenic precautions, not specifically related to platelet count. Requiring visitors to wear respiratory masks and protective clothing (Choice B) is more relevant for patients with airborne precautions. Considering transfusion of packed red blood cells (Choice C) is not indicated for low platelet count but is more appropriate for managing anemia or low hemoglobin levels.
4. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?
- A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
- B. It helps your intestines absorb calcium, which is important for bone formation.
- C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
- D. Vitamin D supplements should not be taken by someone of your age.
Correct answer: B
Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.
5. Which of the following can cause coup-contrecoup injuries?
- A. Rotational forces
- B. Deformation forces
- C. Deceleration forces
- D. Acceleration forces
Correct answer: C
Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.
