You asked to obtain a measurement of serum sodium level in the hospital lab; you obtain a value of 125 mmol/L by repeating the test 5 times. The reference value of serum sodium at that lab is between 135-155 mmol/L. Your measurement is termed
- A. accurate but not precise
- B. precise but not accurate
- C. neither accurate nor precise
- D. both accurate and precise
Correct Answer: C
Rationale: The measurement is consistently low, indicating it is neither close to the true value (inaccurate) nor consistent with the reference range.

To provide safe care for Mrs. Zeno, it is important for the nurse to check the bedside for the presence of:
- A. A tracheostomy set
- B. A hypothermia blanket
- C. An intravenous set-up
- D. A syringe and edrophonium HCl(Tensilon)
Correct Answer: B
Rationale: Checking the bedside for the presence of a hypothermia blanket is crucial for providing safe care for Mrs. Zeno. Hypothermia blankets are used to prevent or treat hypothermia, which is a condition where the body temperature drops below normal levels. Maintaining normothermia (normal body temperature) is important for the overall well-being of patients, especially those who are at risk of developing complications due to temperature fluctuations. Therefore, having a hypothermia blanket readily available at the bedside ensures that the nurse can promptly address any temperature-related issues to optimize Mrs. Zeno's care and safety.
You are discussing the risk of radiotherapy with the parents of a child with medulloblastoma; the mother has a concern about the late neurological complications post radiotherapy. The statement that should be included in the discussion that late neurological sequelae post radiotherapy is more severe with
- A. focal radiotherapy rather than craniospinal irradiation
- B. children with an age of less than 3 year
- C. concomitant chemo-radiotherapy
- D. low grade tumors rather than high grade tumors
Correct Answer: B
Rationale: Younger children (<3 years) are more susceptible to long-term neurotoxic effects of radiotherapy.
A 1-year-old child develops right eye ptosis, miosis, and loss of sweating; you suspect neuroblastoma. The MOST valuable investigation to confirm the diagnosis is
- A. CT scan of the neck and chest
- B. CT scan of the abdomen
- C. CT scan of the brain
- D. magnetic resonance imaging (MRI) of the brain
Correct Answer: A
Rationale: CT scan of the neck and chest can help identify a primary neuroblastoma mass in the adrenal gland or sympathetic chain.
The baby with birth brachial plexus palsy (BBPP) will start with occupational or physical therapy at approximately
- A. 1 wk of age
- B. 2 wk of age
- C. 3 wk of age

Rationale: Early intervention is critical for optimal recovery in BBPP. Therapy typically begins within the first week of life to prevent contractures and promote nerve regeneration.
Clients 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 is preparing Mr. Sy for surgery. Which of the following statements by the client would indicate he is well-informed about his imminent surgery?
- A. " Right after the operation, I will wear the pneumatic compression device while sitting on the chair."
- B. "I will not eat anything after 12 pm the night befire my operation, but I sure can drink."
- C. "The skin preparation site is longer and wider than the actual incision site."
- D. "I will need to sign the consent from after I get to the operating table."
Correct Answer: B
Rationale: Option B, "I will not eat anything after 12 pm the night before my operation, but I sure can drink," indicates that the client understands and is knowledgeable about the pre-operative fasting guidelines. It is crucial for patients to have an empty stomach before surgery to prevent complications related to anesthesia, such as aspiration pneumonia. This statement shows that Mr. Sy is well-informed and compliant with this important pre-operative instruction. Options A, C, and D do not directly demonstrate specific knowledge regarding the surgery preparations.
