Mrs. Go a 75-year old female suffered a fdall and is diagnosed with a herniated nucleus pulposus at the C4-C5 interspace, and a second st the C5-C6 interspace.Which of the following findings would the nurse expect to discover during the assessment?
- A. constant, throbbing headaches
- B. clonus in the lower extremities
- C. Numbness of the face
- D. pain in the scapular region
Correct Answer: D
Rationale: The correct answer is D: pain in the scapular region. This is because a herniated nucleus pulposus at the C4-C5 and C5-C6 interspaces typically results in pain radiating from the neck to the scapular region due to nerve compression at those levels. The other choices are incorrect as constant, throbbing headaches are not typically associated with this specific diagnosis, clonus in the lower extremities is more indicative of lower spinal cord involvement, and numbness of the face is not a common symptom of herniated discs at these levels.

A client is brought to the emergency department in an unconscious condition. The client’s wife hands over the previous medical files and points out that the client had suddenly fallen unconscious after trying to get out of bed. Which of the following is a primary source of information?
- A. Client’s wife
- B. Medical documents
- C. Test results
- D. Assessment data
Correct Answer: A
Rationale: The correct answer is A: Client’s wife. She is the primary source of information as she witnessed the event firsthand and provided relevant details. In this scenario, the wife's account of the event is crucial in understanding the sequence of events leading to the client's unconscious condition. Medical documents (B), test results (C), and assessment data (D) are all secondary sources of information that may provide additional data but do not have the same level of immediacy or firsthand knowledge as the client's wife. In an emergency situation, information from a reliable eyewitness is often the most valuable initial source for healthcare providers to make critical decisions.
The nurse is providing breast cancer education at a community facility. The American Cancer Society recommends that women get with mammograms:
- A. Yearly after age 40
- B. After the birth of the first child and every 2 years thereafter
- C. After the first menstrual period and annually thereafter
- D. Every 3 years between ages 20 and 40 and annually thereafter
Correct Answer: A
Rationale: Step-by-step rationale for why choice A is correct:
1. The American Cancer Society recommends yearly mammograms after age 40 for early breast cancer detection.
2. Mammograms are most effective for women aged 40 and older in detecting breast cancer.
3. Regular mammograms can help detect breast cancer at an early stage, improving treatment outcomes.
Summary of why other choices are incorrect:
B: Mammograms should start at age 40, not after the birth of the first child.
C: Mammograms are not recommended after the first menstrual period; they should start at age 40.
D: Mammograms should be done annually after age 40, not every 3 years between ages 20 and 40.
After cancer chemotherapy, a client experiences nausea and vomiting. The nurse should highest priority to which intervention?
- A. Serving small portions bland food
- B. Encouraging rhythmic breathing exercises
- C. Administering metoclopramide (Reglan) and dexamethasone (Decadron) as prescribed
- D. Withholding fluids for the first 4 to 6 hours after chemotherapy administration
Correct Answer: C
Rationale: The correct answer is C because administering antiemetic medications like metoclopramide and dexamethasone helps control nausea and vomiting post-chemotherapy. Metoclopramide acts on the gut to reduce nausea, while dexamethasone decreases inflammation and suppresses the vomiting reflex. Choice A focuses on dietary interventions but does not address the physiological cause of nausea. Choice B with breathing exercises may help some clients but does not directly address the nausea and vomiting. Choice D is incorrect as withholding fluids can lead to dehydration, which is not recommended after chemotherapy.
The nursing care for the client in addisonian crisis should include which of the following interventions?
- A. Encouraging independence with activities of daily living (ADL)
- B. Allowing ambulation as tolerated
- C. Offering extra blankets and raising the heat in the room to keep the client warm
- D. Placing the client in a private room
Correct Answer: C
Rationale: The correct answer is C because in Addisonian crisis, the client experiences adrenal insufficiency leading to decreased cortisol levels and impaired stress response. Offering extra blankets and raising room temperature helps prevent hypothermia, as clients in crisis are unable to regulate body temperature. Encouraging independence with ADLs (choice A) and ambulation (choice B) are not priorities as the client is in a critical state. Placing the client in a private room (choice D) is not directly related to managing Addisonian crisis.
Which of the following is the most numerous type of white blood cell (WBC)?
- A. Neutrophil
- B. Basophil
- C. Eosinophil
- D. Lymphocyte
Correct Answer: A
Rationale: The correct answer is A: Neutrophil. Neutrophils are the most numerous type of WBC, typically comprising 50-70% of total WBC count. They are key players in the body's immune response, phagocytizing pathogens. Basophils, eosinophils, and lymphocytes are less numerous than neutrophils. Basophils are involved in allergic reactions, eosinophils combat parasitic infections, and lymphocytes play a critical role in adaptive immunity. However, in terms of sheer numbers, neutrophils outnumber the other types of WBC.
