Which is the name of the suture separating the parietal bones at the top center of a newborn's head?
- A. Frontal
- B. Coronal
- C. Sagittal
- D. Occipital
Correct Answer: C
Rationale: The suture separating the parietal bones at the top center of a newborn's head is called the sagittal suture. This suture runs along the top of the skull from front to back, connecting the two parietal bones. It is one of the major cranial sutures that allows for the flexibility and growth of the skull during infancy and childhood.

A client is hospitalized with oat cell carcinoma of the lung. To manage severe pain, the physician prescribes a continuous I.V. infusion of morphine. Which formula should the nurse use to check that the morphine dose is appropriate for the client?
- A. 1 mg/kg of body weight
- B. 5 mg/70kg of body weight
- C. 5 mg/kg of body weight
- D. 10mg/70kg of body weight
Correct Answer: C
Rationale: When calculating the appropriate dose of morphine for a client, the nurse should consider the client's body weight. The most commonly used formula for calculating the appropriate dose of morphine is 0.1 to 0.2 mg/kg of body weight for hourly dosing or 2.5 to 10 mg/kg/day for continuous infusions.

Which of the following is the appropriate nursing diagnosis?
- A. Fluid volume deficit R/T furrow tongue
- B. Fluid volume deficit R/T uncontrolled vomiting
- C. Dehydration R/T subnormal body temperature
- D. Dehydration R/T incessant vomiting
Correct Answer: B
Rationale: The appropriate nursing diagnosis is Fluid volume deficit R/T uncontrolled vomiting. This diagnosis is the most specific and directly related to the issue of vomiting causing a loss of fluids, leading to a deficit in fluid volume. Uncontrolled vomiting can result in a significant loss of fluids and electrolytes, which can lead to dehydration. It is important to address the root cause of the fluid volume deficit, which in this case is the uncontrolled vomiting. The other options may not directly address the primary issue of fluid loss due to vomiting.
What is an advantage of peritoneal dialysis?
- A. Treatments are done in hospitals.
- B. Protein loss is less extensive.
- C. Dietary limitations are not necessary.
- D. Parents and older children can perform treatments.
Correct Answer: B
Rationale: An advantage of peritoneal dialysis is that protein loss is less extensive compared to hemodialysis. Peritoneal dialysis operates by using the peritoneal membrane in the abdomen to act as a natural filter, helping to remove waste products and excess fluids from the body. The process of peritoneal dialysis allows for a slower, more continuous removal of waste substances, which results in reduced protein loss as compared to hemodialysis. This can be beneficial for maintaining overall nutritional status and preventing complications related to protein deficiencies in patients undergoing dialysis treatment.
How many liters per minute of oxygen should be administered to the patient with emphysema?
- A. 2 L/min
- B. 10 L/min
- C. 6 L/min
- D. 95 L/min
Correct Answer: C
Rationale: Oxygen therapy for patients with emphysema aims to maintain adequate oxygen levels in the blood while avoiding toxic levels of oxygen. The recommended flow rate for oxygen administration in patients with emphysema is typically 1-3 liters per minute. Increasing the flow rate above this range may lead to oxygen toxicity in these patients. Therefore, a safe and appropriate oxygen flow rate for a patient with emphysema would be around 6 L/min, making option C, 6 L/min, the correct choice from the provided options.
