A client is receiving methotrexate (Mexate), 12g/m2 IV to treat osteogenic carcinoma. During methotrexate therapy, the nurse expects the client to receive which other drug to protect normal cells?
- A. Probenecid (Benemid)
- B. Cytarabine (ara-C, cystosine arabinoside [Cytosar-U])
- C. Thioguanine (6-thioguanine, 6-TG)
- D. Leucovorin (Citrovorum factor or folinic acid [wellcovirin])
Correct Answer: D
Rationale: The correct answer is D: Leucovorin. Leucovorin is given during methotrexate therapy to protect normal cells by acting as a rescue agent that helps to reduce the toxic effects of methotrexate. It works by enhancing the efficacy of methotrexate in cancer cells while reducing its toxicity in normal cells. Probenecid (A) is not used to protect normal cells during methotrexate therapy. Cytarabine (B) and Thioguanine (C) are other chemotherapeutic agents and are not typically given to protect normal cells during methotrexate therapy.

Tic douloureux is a (n) ___ cranial nerve disorder characterized by paroxysms of pain and burning sensations.
- A. 1st
- B. 7th
- C. 5th
- D. 8th
Correct Answer: C
Rationale: The correct answer is C: 5th cranial nerve. Tic douloureux, also known as trigeminal neuralgia, is characterized by severe facial pain. The trigeminal nerve, the 5th cranial nerve, is responsible for sensory input from the face. This nerve is commonly affected in cases of tic douloureux, leading to sharp, shooting pain in the face. Choices A, B, and D are incorrect because the 1st cranial nerve (olfactory nerve), 7th cranial nerve (facial nerve), and 8th cranial nerve (vestibulocochlear nerve) are not typically associated with the symptoms of tic douloureux.
Which method of data collection will the nurse use to establish a patient’s database?
- A. Reviewing the current literature to determine evidence-based nursing actions
- B. Checking orders for diagnostic and laboratory tests
- C. Performing a physical examination
- D. Ordering medications
Correct Answer: C
Rationale: The correct answer is C: Performing a physical examination. This method allows the nurse to collect objective data directly from the patient, which is crucial in establishing a comprehensive patient database. By assessing the patient's physical condition, the nurse can gather vital information such as vital signs, overall health status, and potential areas of concern. Reviewing literature (A) and checking orders for tests (B) may provide additional insights but are not direct data collection methods. Ordering medications (D) is a treatment intervention, not a data collection method.
The nurse is performing an assessment of a client who has a small wound on the knee, collecting cues about the client’s health status. Which of the following would the nurse identify as a subjective cue?
- A. Sharp pain in the knee
- B. Small bloody drainage on dressing
- C. Temperature of 102 degrees F
- D. Pulse rate of 90 beats per minute
Correct Answer: A
Rationale: The correct answer is A because sharp pain is a subjective cue as it is based on the client's personal experience and perception. The client is the only one who can report the presence and intensity of pain.
B: Small bloody drainage is an objective cue that can be observed and measured by the nurse.
C: Temperature of 102 degrees F is an objective cue that can be measured using a thermometer.
D: Pulse rate of 90 beats per minute is an objective cue that can be measured using a pulse oximeter.
In summary, subjective cues are based on the client's feelings and perceptions, while objective cues are observable and measurable by the healthcare provider.
Clients who will go through operations and who have undergone surgery need the proper observation, treatment and care. Implementing the nursing process to these patients will help reduce complications. Nurse Maria checks on Mr. Alberto who had abdominal surgery, and finds that the edges of the incision have separated. Also, a small portion of the bowel is sticking out through the incision. Nurse Maria would:
- A. cover wound with moist sterile dressing
- B. find out how this happened
- C. place sterile dry gauze on the wound
- D. pour sterile water into the wound
Correct Answer: A
Rationale: Correct Answer: A: Cover wound with moist sterile dressing
Rationale:
1. Covering the wound with a moist sterile dressing helps maintain a clean and moist environment, promoting wound healing.
2. Moist dressing prevents the wound from drying out and minimizes the risk of infection.
3. The moist environment supports healing by promoting cell growth and preventing tissue damage.
4. It protects the exposed bowel from further injury and contamination.
Summary:
B: Finding out how this happened is important but not an immediate priority for patient care.
C: Placing sterile dry gauze can lead to the wound drying out and hinder healing.
D: Pouring sterile water into the wound is not recommended as it can introduce contaminants and is not considered standard care for this situation.
The nurse will monitor J.E. for the following signs and symptoms:
- A. Change in the levei of consciousness, tachypnea, tachycardia, petechiae
- B. Onset of chest pain, tachycardia, diaphoresis, nausea and vomiting
- C. Loss of consciousness, bradycardia, petechiae, and severe leg pain
- D. Change in leve! of consciousness, bradycardia, chest pain and oliguria
Correct Answer: A
Rationale: The correct answer is A.
1. Change in level of consciousness is crucial in assessing neurological status.
2. Tachypnea indicates possible respiratory distress or oxygenation issues.
3. Tachycardia may suggest a cardiovascular problem or inadequate perfusion.
4. Petechiae can be a sign of bleeding disorders or sepsis.
Option B is incorrect because chest pain, diaphoresis, and nausea/vomiting are more indicative of a cardiac event rather than monitoring for J.E.'s signs and symptoms.
Option C is incorrect because loss of consciousness, bradycardia, and leg pain do not align with the signs and symptoms to monitor for J.E.
Option D is incorrect because bradycardia, chest pain, and oliguria are not as comprehensive as the signs and symptoms listed in option A for monitoring J.E.
